    v.
    WORKERS’ COMPENSATION
    APPEALS BOARD and D.C.,
    Respondents.
    I. INTRODUCTION
    Respondent injured worker, D.C. (Worker),1 was employed by petitioner Applied
    Materials from 1996 until 2008. During that time, she claimed three industrial injuries:
    1
    Since this case involves allegations of sexual abuse, we refer to the injured
    worker by her initials or the status designation “Worker” to protect her privacy. (See e.g.
    Baker v. Workers’ Comp. Appeals Bd. (2011) 
    52 Cal.4th 434
    , 439, fn. 3 [court used
    initials for a fictitious name to protect injured worker’s medical privacy]; Western
    (continued)
    a specific injury to her neck and right upper extremity in 2001, a specific injury to her
    neck and both upper extremities in 2005, and a cumulative trauma injury to her neck,
    both upper extremities, and psyche ending on her last day worked in January 2008.
    Worker claimed her injuries were due to the constant, repeated use of a computer
    keyboard and mouse at work. After the first injury in 2001, Worker returned to work on
    modified duty and continued to perform modified work—punctuated by periods of total
    temporary disability—until 2008. In 2006, Worker developed injuries to her psyche (a
    pain disorder due to her chronic pain, an anxiety disorder, and depression), which she
    claimed were industrial because they were compensable consequences of her physical
    injuries. Worker later claimed that in 2013, she was sexually exploited by Dr. John
    Massey, the physician primarily responsible for the treatment of her industrial injuries.
    She claimed that he touched her inappropriately on multiple occasions at his clinic and
    had sexual intercourse with her five times in her home. As a result of the doctor’s alleged
    misconduct, Worker claimed that she suffered a further injury to her psyche and was
    diagnosed with posttraumatic stress disorder (PTSD). Worker claimed her PTSD was
    industrial as a compensable consequence of the medical treatment her employer provided
    for all three of her industrial injuries.
    Arrowood Indemnity Company (Arrowood)—the workers’ compensation carrier
    for the 2001 specific injury claim—accepted liability for Worker’s 2001 physical injury
    claims, but disputed liability for her psychiatric injuries, including PTSD, on a variety of
    grounds. XL Specialty Insurance Company, as administered by Corvel Corporation
    (hereafter XL Specialty)—the workers’ compensation carrier for both the 2005 specific
    injury and the 2008 cumulative trauma injury claims—denied liability for Worker’s
    physical and psychiatric injuries, arguing among other things that Worker’s injuries were

    155 Cal.App.3d 366
    , 368 [appellate court
    referred to flight attendant who was raped as “claimant” and did not state her name].)
    2
    all due to the 2001 injury. Both insurers contended that Worker’s psychiatric injury
    (PTSD) resulting from her claimed sexual exploitation by Dr. Massey was not industrial
    because it was the result of a consensual sexual relationship and occurred at her home.
    The case went to trial before a workers’ compensation judge (WCJ) in 2017. The
    WCJ found that all of Worker’s injury claims—including her depression, anxiety, and
    PTSD—were industrial; ordered XL Specialty to pay two years’ back temporary
    disability (TD); awarded Worker 100 percent permanent disability (sometimes PD) based
    on her PTSD alone retroactive to October 2010; found no apportionment; and concluded
    that the insurers were jointly and severally liable for the PD award since Dr. Massey
    treated all three of her industrial injuries. All parties (Applied Materials, Arrowood, XL
    Specialty, and Worker) petitioned the Workers’ Compensation Appeals Board (WCAB)
    for reconsideration. The WCAB granted reconsideration. In its June 2019 decision, the
    WCAB amended the amount of the weekly TD and PD rates as recommended by the
    WCJ, made an order regarding attorney fees that is not at issue here, and otherwise
    affirmed the WCJ’s findings and award.
    Arrowood and XL Specialty filed separate petitions for review of the WCAB’s
    decision.2 We granted review in both cases and ordered the two petitions considered
    together for further briefing, oral argument, and disposition.
    II. CONTENTIONS AND CONCLUSIONS ON WRIT REVIEW
    (1) XL Specialty contends that the correct date of injury for the cumulative trauma
    claim was in March 2002 (during Arrowood’s coverage) and that the WCAB erred in
    finding a cumulative trauma injury in 2008 (during XL Specialty’s coverage).
    2
    Arrowood’s petition also names the employer, Applied Materials, as a
    petitioner. XL Specialty’s petition identifies the petitioner as “XL Specialty Insurance
    Company as administered by Corvel,” but does not name the employer as a petitioner.
    For ease of reference, we shall refer to petitioners Applied Materials and Arrowood
    jointly as “Arrowood” and all petitioners jointly as “Petitioners.”
    3
    Reviewing the entire record, we conclude there was substantial evidence of repeated
    exposure to injury causing events and new injuries after 2005 that supported the WCAB’s
    finding of cumulative trauma ending in 2008. We therefore reject XL Specialty’s
    contention that the correct date of injury for the cumulative trauma was in 2002.
    (2) Both petitioners challenge the WCAB’s finding of industrial causation, arguing
    that the sexual activity between Worker and Dr. Massey was not medical treatment, was
    consensual, and broke the chain of industrial causation. We conclude that Worker met
    her burden of proving that her PTSD was a compensable consequence injury that resulted
    from the treatment for her industrial injuries and that her employment was one of the
    contributing causes without which her PTSD would not have occurred. We reject the
    contention that the sexual conduct here was consensual, since as a matter of law a patient
    cannot consent to sexual contact with his or her physician. (Bus. & Prof. Code, § 729,
    subd. (b).) We also reject Petitioners’ contention that Worker’s PTSD is not
    compensable under the rules governing industrial injuries arising out of assaults by third
    parties.
    (3) We reject XL Specialty’s contention that it is not liable for Worker’s
    psychiatric disability since it did not authorize or pay for any of the treatment with
    Dr. Massey or his clinic. Substantial evidence supports the WCAB’s conclusion that
    Dr. Massey treated Worker for all three injuries, including the injuries she sustained
    during XL Specialty’s coverage period.
    (4) We reject XL Specialty’s challenges to the sufficiency of Dr. Steven
    Feinberg’s agreed medical examiner (AME) reports to support the WCAB’s finding of
    orthopedic injuries during XL Specialty’s coverage period. Contrary to XL Specialty’s
    assertions, the AME’s evaluation included an extensive review of Worker’s medical
    records and it was not necessary for the AME to reexamine Worker after 2011 to opine
    regarding industrial causation since her injuries predated 2008.
    4
    (5) We reject Arrowood’s challenges to the sufficiency of the evidence to support
    the WCAB’s findings of psychiatric injury due to the 2001 injury. We conclude that
    substantial evidence supported the WCAB’s finding that Worker’s PTSD was due in part
    to her 2001 injury since Dr. Massey treated Worker for all three injuries and Arrowood
    authorized and paid for the treatment.
    (6) We reject Arrowood’s challenge to the sufficiency of the evidence to support a
    finding of new and further disability within five years of the November 2001 injury.
    We conclude that there was substantial evidence of a new need for medical treatment,
    including psychiatric treatment, before November 2006 that supported the WCAB’s
    implied finding of new and further disability from the November 2001 injury.
    (7) We reject Arrowood’s challenge to the sufficiency of the medical reports from
    Dr. Allan Sidle (the psychiatric qualified medical examiner (QME)) to support the PD
    award, which challenge is based on Arrowood’s contention that the QME relied on the
    wrong PD rating schedule. Arrowood asserts that the 1997 Schedule for Rating
    Permanent Disabilities (1997 Schedule)3 applies to the 2001 injury, that the QME
    described Worker’s PD in accordance with the 2005 Schedule for Rating Permanent
    Disabilities (2005 Schedule)4, and that he failed to describe Worker’s disability in
    accordance with the 1997 Schedule. We will hold that in the circumstances in this case,
    the 2005 Schedule applies to the psychiatric PD claim.
    (8) We conclude that the 100 percent PD award must be annulled because
    Dr. Sidle’s reports that the WCAB relied on do not constitute substantial evidence since
    Dr. Sidle relied on an incorrect legal theory, the alternative path theory, that was
    subsequently rejected in Department of Corrections & Rehabilitation v. Workers’ Comp.
    California Department of Industrial Relations, Division of Workers’
    3
    Compensation, Schedule for Rating Permanent Disabilities (April 1997).

    5
    Appeals Bd. (2018) 
    27 Cal.App.5th 607
     (Fitzpatrick). We also conclude that Worker’s
    evidence was otherwise insufficient to rebut the scheduled rating for her psychiatric
    disability, which was 68 or 70 percent.
    (9) Arrowood challenges the WCAB’s finding of no apportionment on three
    grounds. It contends that Dr. Sidle’s opinions are not substantial evidence because he
    (1) failed to apportion between the three industrial injuries and opined that the three
    injuries were inextricably intertwined; (2) failed to apportion to nonindustrial factors; and
    (3) failed to apportion to the pain disorder and depression that predated her PTSD
    diagnosis. Since we annul the PD award and remand for further proceedings, we do not
    address Arrowood’s contentions, but we do review the rules governing apportionment for
    the guidance of the WCAB and parties on remand.
    (10) Finally, we reject Arrowood’s contentions that the WCAB ordered total PD
    benefits at the wrong weekly rate for the 2001 injury and that the WCAB erred in
    ordering it to administer the joint and several PD award. Since Arrowood failed to raise
    these issues in its petition for reconsideration to the WCAB, these points have been
    waived and are not cognizable in these proceedings.
    In view of our conclusions, we will annul the award and remand to the WCAB for
    further proceedings consistent with our opinion.
    III. FACTUAL AND PROCEDURAL HISTORY
    A. History of Industrial Injuries, Medical Treatment, and Workers’ Compensation
    Claims
    Worker began working for Applied Materials in 1996 as an administrative
    assistant and was eventually promoted to program manager for marketing,
    communications, and international training programs. The history of her industrial
    injuries is complex, with three dates of injury, injuries to multiple body parts, numerous
    6
    diagnoses, compensable consequence injuries, “massive” amounts of treatment over
    16 years (2001 to 2017), and at least 26 medical-legal evaluations.
    In November 2001, Worker developed pain in her neck and her right elbow, wrist,
    and shoulder, with numbness and tingling in the right hand and fingers, which she
    attributed to the constant, repeated use of a computer keyboard and mouse at work. Her
    diagnoses included tendonitis, mild carpal tunnel syndrome, epicondylitis, cervical
    myofascial pain, and mild degenerative changes in her neck. For the first few years, she
    was treated primarily by Dr. Sunita Jayakar. Worker received conservative treatment,
    including cortisone injections in the elbow and neck, physical therapy, chiropractic
    adjustments, medication, biofeedback, acupuncture, splints, and trigger point injections.
    Dr. Jayakar also placed her on modified duties, with her work hours reduced to half-days
    for six months. Her work restrictions included limiting her use of a computer keyboard
    and mouse. Worker returned to work full time on October 1, 2002. She had flare-ups in
    2003 and 2004 and was restricted to working half days for three months in early 2004.
    Dr. Jayakar declared her condition permanent and stationary in November 2002 and
    again in April 2004.
    Arrowood was the workers’ compensation insurer for the 2001 injury. In June
    2005, Worker—who was then self-represented—and Arrowood entered into stipulations
    with request for an award based on Dr. Jayakar’s reports. They stipulated that Worker
    had sustained a specific industrial injury on November 27, 2001, to her neck and right
    arm that resulted in 33 percent PD and that she was entitled to future medical care. A
    WCJ approved the stipulated award.
    In May 2005, Worker began to complain of pain in her left wrist, elbow, and
    shoulder, radiating to her neck and upper back, which resulted in part from overuse of her
    left arm due to the injury to her right arm. She reported this injury to her employer and
    filed a new claim for workers’ compensation benefits. From 2005 until 2008, Applied
    7
    Materials was insured for workers’ compensation by XL Specialty.5 Worker’s diagnoses
    in 2005 and 2006 included left wrist, biceps, and elbow tendonitis; lateral epicondylitis;
    upper extremity overuse/repetitive strain injury; carpal tunnel syndrome; trapezius strain;
    cervical strain with asymptomatic degenerative changes in her neck; cervical myofascial
    pain; and chronic pain syndrome. XL Specialty denied liability for the 2005 injury.
    In February 2006, Worker saw Dr. Ronald Fujimoto, a pain specialist at
    RehabOne, a rehabilitation and pain clinic, regarding a possible transfer of care. He
    noted that she was still working and reported that he had nothing to offer her. A month
    later, Dr. Fujimoto requested authorization to refer her to a psychologist for pain
    management and biofeedback. Worker returned to Dr. Jayakar, who later referred her to
    the Bay Area Pain and Wellness Clinic (BAPWC). In April 2006, Worker complained to
    a consulting orthopedist that she was depressed secondary to her industrial injuries.
    In July 2006, Worker consulted with Dr. Steven Feinberg (an orthopedist at
    BAPWC) and Dr. Greg Garavanian (a BAPWC psychologist) to determine whether she
    might benefit from BAPWC’s multi-disciplinary approach. Dr. Feinberg recommended
    she complete BAPWC’s 200-hour functional restoration program, which included daily
    classes, physical therapy, and psychological counseling. Dr. Garavanian diagnosed a
    chronic pain disorder and a sleep disorder due to chronic pain. He also recommended
    Worker complete the functional restoration program. In August 2006, Worker
    transferred her treatment to Dr. Alpana Gowda, a pain specialist at BAPWC. In addition
    to the physical injuries, Dr. Gowda diagnosed Worker with depression. Worker was off
    work again for 11 months from June 2006 until May 2007.
    5
    It is not clear from the record precisely when XL Specialty provided coverage
    (i.e., when its policies incepted and when they ended), but it is undisputed that XL
    Specialty insured Applied Materials for workers’ compensation liability from May 2005
    through January 2008.
    8
    In October 2006, Worker filed a petition to reopen her workers’ compensation
    case for her 2001 injury due to new and further disability. (At trial, the parties stipulated
    that the petition to reopen was timely filed.)
    In late October 2006, Worker started the functional restoration program at
    BAPWC, but left after four days because of anxiety. Worker continued to treat with
    Dr. Gowda, who recommended psychotherapy and referred her to BAPWC’s psychiatrist,
    Dr. Gordon Walker, to treat her anxiety and depression. Dr. Walker diagnosed Worker
    with major depression, a generalized anxiety disorder, and chronic pain disorder due to
    her industrial injuries. In February 2007, Dr. Gowda reported that Worker’s depression
    and anxiety were “overwhelming.”
    Later in 2007, Dr. John Massey (an anesthesiologist/pain specialist) replaced
    Dr. Gowda as Worker’s primary treating physician at BAPWC. Worker received medical
    treatment from BAPWC for more than seven years: from August 2006 until December
    2013. During that time, Dr. Massey managed her overall treatment, treated her physical
    injuries, and prescribed medication for both her physical and psychiatric injuries. A
    psychiatrist (Dr. Walker and later Dr. James Weiss) prescribed medication for her
    psychiatric injuries, and multiple psychologists provided psychotherapy, including
    cognitive behavioral therapy and pain counseling. Worker’s treatment at BAPWC
    included medication, physical therapy, acupuncture, trigger point injections, a TENS
    (transcutaneous electrical nerve stimulation) unit, and cervical epidural injections. Her
    medications included pain killers, opioids, anti-depressants, anti-neuropathic drugs,
    anti-inflammatory drugs, and anti-anxiety drugs.
    In May 2007, Worker returned to work part-time on modified duty; by October
    2007, she was back to work full time on modified duty. Applied Materials laid Worker
    off in January 2008, after her position was eliminated. She was 44 years old at that time.
    She subsequently claimed a cumulative trauma injury to her neck, upper extremities, and
    9
    psyche through January 15, 2008 (her last day worked). XL Specialty denied that claim,
    too.
    In early 2008, Worker completed the eight-week functional restoration program at
    BAPWC. In May 2008, Dr. Mark Bernhard examined her as a QME in orthopedics. He
    opined that her symptoms were complex with some magnification and somatization in
    excess of what would be expected from her objective findings. He concluded that her
    orthopedic condition was permanent and stationary, described her factors of disability,
    and apportioned 10 percent of her PD to preexisting, nonindustrial degenerative changes
    and apportioned the remaining 90 percent of her PD equally between her 2001 and 2005
    injuries.
    In September 2008, Worker enrolled in graduate school at Golden Gate
    University, where she obtained a master’s degree in human resources management in
    2009.
    In 2009, Dr. Massey concluded that Worker was permanent and stationary from an
    orthopedic standpoint, but still needed psychiatric treatment. He also opined that the
    “combination of her orthopedic issues and her psychiatric comorbidity make her
    unemployable in the open labor market” and that she could never “reliably return to
    work.” In December 2009, Worker had low back surgery on a nonindustrial basis. In
    2010, she fell at home and tore a ligament in her left foot, which required surgery.
    Worker later claimed that her low back and left foot injuries were industrial. The
    medical-legal evaluators disagreed as to whether those injuries were industrial, and the
    WCJ found that they were not. (That finding is not at issue here.)
    In May 2010, Worker’s counsel obtained a medical-legal report from Dr. Massey.
    He reported that her condition was permanent and stationary from an orthopedic
    standpoint, but that he was not qualified to opine regarding her psychiatric condition or
    disability. He nonetheless opined that the combination of her “orthopedic and
    10
    psychologic impairment leaves her unable to compete in the open labor market” and that
    the disabilities to her low back and leg, when combined with her neck and upper
    extremity conditions, result in 100 percent PD.
    In January 2011, Worker and Arrowood entered into a “Stipulation and Award
    and/or Order.” They stipulated that Arrowood would continue to provide medical care
    pursuant to the open award in the 2001 case with Dr. Massey as the treating physician;
    that Arrowood would authorize “[a]ll reasonable care requests by Dr. Massey,” and that
    Dr. Feinberg—who was no longer with BAPWC—would serve as an AME as to all
    medical and medical-legal issues, including the petition to reopen. A WCJ approved that
    stipulation and order.
    When Worker saw Dr. Feinberg for the agreed medical examination in May 2011,
    she complained of constant neck pain that radiated to both shoulders, down her arms and
    into both elbows; prickly, stabbing pains and weakness in both elbows; pain in her hands,
    wrists, and right thumb, with pins and needles sensations in three fingers on her left hand;
    pain in her low back, left leg, and foot; and difficulty sleeping. “Every task flare[d] up
    her pain.” She appeared “very depressed” and “hopeless” and was taking 14
    medications. Dr. Feinberg opined that her condition was not permanent and stationary,
    that her upper body symptoms were partially related to her 2001 injury and partially due
    to cumulative trauma through January 15, 2008; that she remained temporarily disabled
    and needed further diagnostic studies for her neck; that her prognosis for future
    employment was grim; that she was significantly depressed and overmedicated and
    needed to be “detoxified.”
    Dr. Jeffrey Holmes was the orthopedic QME for the 2008 cumulative trauma
    claim. He examined Worker on April 28, 2011, and declared her orthopedic condition
    permanent and stationary as of that date. Dr. Holmes opined that the injuries to her neck
    and upper extremities were due to “a prolonged cumulative trauma” that began in 2001
    11
    and continued through the end of her employment in 2008 and that “[t]he entire period is
    responsible for” the disability in her cervical spine and arms.
    Dr. Sidle was the psychiatric QME for XL Specialty’s 2008 cumulative trauma
    claim. He reported that Worker appeared “significantly overmedicated,” “was not fully
    oriented,” and exhibited problems with memory and concentration when he examined her
    in April 2011. He diagnosed a pain disorder due to the interaction of her underlying
    psychological issues and her musculoskeletal injuries, an anxiety disorder (panic disorder
    with agoraphobia), and a major depressive disorder. He opined that the predominant
    cause of her psychiatric complaints was the cumulative trauma ending on January 15,
    2008, and that her psychiatric injuries were a compensable consequence of her physical
    injuries. He stated that her condition was not yet permanent and stationary, that she was
    temporarily disabled due to her psychiatric injuries, and that she would not stabilize until
    Dr. Weiss found an effective medication regimen for her. Dr. Sidle reported that when
    her condition stabilizes, he would consider apportionment to nonindustrial factors (her
    abusive childhood, alcoholic parents, the failure of her relationship with her daughter’s
    father).
    In 2012, Arrowood implemented a Medical Provider Network (MPN)—a network
    of health care providers approved by the Department of Industrial Relations to treat
    injured workers (Lab. Code,6 § 4616, subd. (a)(1))—and notified Worker of her right to
    select a physician within the MPN. According to Arrowood’s petition, Dr. Massey was
    in its MPN and Arrowood told Worker she could continue seeing him.
    Dr. Sidle saw Worker again in January 2013. She said she had been severely
    depressed and suicidal for months and thought she would benefit from inpatient
    psychiatric care. She was receiving social security disability and long-term disability
    benefits, which were being authorized by Dr. Massey. Dr. Sidle reported that her
    6
    All undesignated statutory references are to the Labor Code.
    12
    depression had become more severe than before. He opined that Worker’s anxiety,
    depression, and pain disorder were compensable consequences of her physical injuries
    from the 2008 cumulative trauma claim; that she was no longer overmedicated; and that
    she was temporarily disabled by her psychiatric injury and “urgently needed” inpatient
    treatment. He recommended an inpatient program because Worker was in a very
    vulnerable state and at a high risk for suicide. This was about the time Dr. Massey
    started making inappropriate comments of a sexual nature to Worker. (Worker never
    received the inpatient treatment.)
    B. Sexual Exploitation by Dr. Massey7
    On five occasions between May 22 and June 25, 2013, Dr. Massey went to
    Worker’s home during the day. Each time, she let him in; they talked and then he led her
    to her bedroom, where they had sexual intercourse. The first time, she told him she did
    not date married men, did not want to have sex with him, and thought it was “weird”
    because he was her doctor. But she did not resist his advances either. She froze. She did
    not know how to deal with the situation and did not feel empowered to tell him to leave.
    He was her doctor and she thought he had her best interest in mind.
    Starting in 2012—long before Dr. Massey began coming to her home—he hugged
    her in suggestive ways and engaged in sexual banter with her in exam rooms at BAPWC
    as a way of grooming her for what happened later. Several times, he asked her if she was
    in a relationship, told her she was “hot,” said she “ ‘should be getting laid,’ ” and
    commented on the size of her breasts. Dr. Massey made a comment about her breasts in
    front of other staff while administering a steroid injection. A few days before their first
    7
    This section of the statement of facts is based on Worker’s testimony both in
    deposition and at the trial before the WCJ. The deposition transcripts were placed in
    evidence at trial and the parties asked the WCJ to consider the deposition testimony we
    rely on.
    13
    sexual encounter, while examining her at BAPWC, he asked her about her sex life again
    and said, “ ‘[W]ell, you know I would do you.’ ”
    On many occasions after they started having sex, Dr. Massey made sexual
    comments, touched her in a sexual way, kissed her, groped her, or had her touch his erect
    penis in exam rooms at BAPWC. On July 31, 2013, Worker had a panic attack in front
    of other patients in the gym at BAPWC after Dr. Massey tried to get her into an exam
    room.
    Dr. Massey continued to go to Worker’s home after their fifth sexual encounter.
    He went there six times between July 14 and October 10, 2013. He asked her for sex, but
    on those occasions, she refused him. Dr. Massey telephoned Worker more than 70 times
    between May and November 2013. Worker testified that Dr. Massey controlled her
    treatment and disability benefits and told her multiple times “that if anyone found out
    about the affair,” he would have to stop being her doctor and would no longer complete
    her disability forms. She was overmedicated and felt stuck because he was her treating
    physician. As things progressed, she felt “threatened” by the role he played in her care.
    Worker testified that she did not enjoy any of their sexual interactions and that it was not
    something she wanted to do.
    In June 2013, Worker told her wellness instructor at BAPWC about the sexual
    conduct with Dr. Massey, and the instructor reported the matter to BAPWC management.
    Shortly thereafter, Dr. Massey asked Worker to deny that anything had happened
    between them; he later told Worker that BAPWC was thinking about suspending him and
    asked her to lie about their sexual relationship. Worker continued to be treated by
    BAPWC and Dr. Massey until December 12, 2013.

    In May 2014, Worker contacted the Medical Board of California (Medical Board).
    The clinic, the police, and the Medical Board investigated her claims.8 Worker told
    Dr. Sidle that the Medical Board and police investigations had been “very stressful” and
    “a little terrifying.” In September 2016, the Medical Board filed a formal accusation
    against Dr. Massey and charged him with multiple causes of action for discipline. The
    first cause of action alleged unprofessional conduct, sexual misconduct, gross negligence,
    repeated acts of negligence, and incompetence in violation of Business and Professions
    Code sections 726, 2234, and 2236 based on his relationship with and care and treatment
    of Worker. It asserted that while sexually exploiting her, Dr. Massey prescribed six
    medications: narcotic and neuropathic pain relievers, a potent opioid, a hypnotic for
    insomnia, an anti-depressant, and a psychotropic for anxiety. The matter went to a
    formal hearing before the Medical Board; after the hearing, the Medical Board revoked
    Dr. Massey’s license.9
    In November 2013, Dr. Paul Michaels did a psychiatric QME evaluation for
    Arrowood. Worker told him she was quite vulnerable and felt manipulated, seduced, and
    betrayed by Dr. Massey. Dr. Michaels diagnosed major depression and chronic pain. He
    opined that there was no evidence of any psychiatric injury from her 2001 industrial
    injury, that her psychiatric injury was “most likely the result of the cumulative trauma
    8
    Worker also alleged that in early 2013, a male psychologist who had treated her
    six times at BAPWC came to her home, made remarks of a sexual nature that made her
    extremely uncomfortable, gave her an art book with sexually suggestive images, and
    asked her out. Worker advised BAPWC that she no longer wished to be treated by the
    psychologist. Although she considered filing a complaint against him with the applicable
    licensing board, she did not do so.
    9
    Arrowood’s petition asserts that the Medical Board revoked Dr. Massey’s
    medical license in 2018. There is no evidence of that in the record. On the court’s own
    motion, we shall take judicial notice of the First District Court of Appeal’s 2019 order in
    case No. A157859 denying Dr. Massey’s request for writ relief from the Medical Board’s
    order revoking his license and the California Supreme Court’s order denying his petition
    for review of that order in case No. S257281.
    15
    through 2008.” He stated that her condition had not been properly treated with either
    appropriate medications or psychotherapy and that she had been temporarily disabled on
    a psychiatric basis since early 2013 due to Dr. Massey’s inappropriate conduct, and not
    her physical injuries.
    C. Medical and Psychiatric Treatment and Evaluations After December 2013
    In December 2013, Worker transferred her treatment to RehabOne, where she
    received treatment from Dr. Melinda Brown (physical medicine), Dr. Janet Kraemer
    (psychologist), and Dr. Ronald Diebel (psychiatrist). Worker testified that Dr. Brown
    took her off most of her medications and that if she had not been overmedicated, she
    would have been able to refuse Dr. Massey’s advances. In December 2013, Dr. Brown
    reported that Worker needed psychiatric treatment to monitor and reduce her reliance on
    medications, a neurosurgical consultation to put the issue of neck surgery to rest, and
    psychotherapy for pain management. Worker received extensive treatment at RehabOne
    and was still treating there when the case went to trial in May 2017. Over the years,
    authorization for much of the treatment Dr. Brown recommended, including medications
    she prescribed, was denied or delayed in the workers’ compensation utilization review
    process.
    In January 2014, Worker returned to Dr. Sidle (XL Specialty’s psychiatric QME).
    She complained of nightmares, a 30-pound weight loss, and difficulty trusting male
    health care workers. Dr. Sidle agreed that she was still temporarily disabled and “not yet
    permanent and stationary psychiatrically.” He noted that the question whether Worker’s
    injuries that were due to Dr. Massey’s inappropriate sexual conduct should be considered
    industrial and compensable is a legal, not a medical question. He nonetheless opined that
    they should be considered compensable because Dr. Massey treated her for her “accepted
    physical injuries.” Dr. Sidle stated that if her allegations were true, Dr. Massey’s conduct
    was “clearly not within the bounds of appropriate ethical behavior.” He again suggested
    16
    that when Worker’s condition becomes permanent and stationary, apportionment to
    nonindustrial stressors would be appropriate.
    Worker started receiving psychotherapy with Dr. Kraemer, the psychologist at
    RehabOne, in May 2014. Dr. Kraemer diagnosed severe major depression and severe
    PTSD with panic attacks. Initially, Dr. Kraemer limited her treatment to Worker’s pain
    disorder because the insurance carriers had denied liability for the PTSD, reasoning that it
    was due to her sexual relationship with Dr. Massey and not her industrial injuries.
    Dr. Sidle reexamined Worker in March 2015. He noted that her psychiatric
    condition was worsening, due in part to the investigations into her allegations against
    Dr. Massey, and that her new psychologist had diagnosed PTSD. Dr. Sidle disagreed
    with that diagnosis. Worker reported being very fearful of running into Dr. Massey or his
    family, who lived near her home. Dr. Sidle opined that cumulative trauma from 2001 to
    2008 was a predominant cause of her psychiatric injury, that her psychiatric conditions
    were a compensable consequence of her accepted physical injuries, that there was
    additional exposure due to what happened with Dr. Massey, and that Worker needed
    additional treatment that should be paid for on an industrial basis.
    Dr. Sidle saw Worker again in January 2016. She disclosed more details about her
    sexual contacts with Dr. Massey and said she still had nightmares about their encounters
    and no longer felt safe in her own home. Dr. Sidle noted that she appeared more anxious
    and depressed than previously. Based on the new information, Dr. Sidle revised his
    diagnosis and agreed that she had PTSD. He said her PTSD encompassed “her anxiety
    and depression rather than diagnosing each of them separately.” He also diagnosed a
    pain disorder. He stated that her PTSD was “100% industrial” because Dr. Massey “had
    been assigned by Worker’s [sic] Comp to treat her Worker’s [sic] Comp injury” and was
    filling out her disability forms. Dr. Sidle opined that she was permanent and stationary
    and assigned a Global Assessment of Function (GAF) score of 45, which he said he
    17
    understood to mean “that she cannot hold a job” and would be “considered totally
    disabled.” He stated that she needed future medical care (counseling, psychiatric
    treatment, and medication). He opined that she was 100 percent permanently disabled
    based on her psychiatric condition alone and was unable to work. The factors that
    impacted her ability to work included her anxiety and depression, difficulty with sleep,
    decreased energy, and decreased concentration. He opined that it was not possible for her
    to meet the demands of an employer on a steady basis eight hours a day, five days a
    week.
    Dr. Kraemer reported in January 2016 that she had seen Worker for 22
    psychotherapy sessions. Because the carriers had denied liability for her PTSD,
    Dr. Kraemer had chosen interventions that would help her depression, anxiety, and
    PTSD, but stated that her mental state would not improve without treating her PTSD
    directly. Dr. Kraemer opined that Worker’s PTSD was industrial. She stated that
    Worker was reluctant to tell Dr. Sidle what actually happened with Dr. Massey and as a
    result gave him “the impression that this was something in the nature of a distressing
    consentual [sic] affair, instead of a series of 5 nonconsensual, sexual violations, each
    more traumatizing, with one being especially painful and traumatic.” She noted that
    Worker’s relationship with Dr. Massey “was inherently unequal,” that she was
    overmedicated and dependent on him for her prescriptions. Dr. Kraemer echoed
    Dr. Sidle’s opinions regarding Worker’s ability to work and compete in an open labor
    market.
    In deposition, Dr. Sidle explained that PTSD may now be diagnosed based on a
    sexual violation. He stated that Dr. Massey was a powerful male authority figure who
    had financial power over Worker, who she relied on to improve her physical condition,
    and that it is below the standard of care for a doctor to have sex with a patient because it
    abuses the power relationship and takes advantage of a vulnerability, especially in a
    18
    patient like Worker, who was medicated and already feeling bad about herself. Despite
    his earlier reports, he testified that there was no apportionment of her psychiatric PD to
    nonindustrial stressors; that the 100 percent PD was due entirely to her PTSD, which was
    due entirely to her sexual relationship with Dr. Massey; and that her pain disorder was
    not responsible for her PD.
    In 2017, Dr. Kraemer began treating Worker’s PTSD. The treatment was initially
    authorized by one of the insurers, then objected to and provided on a self-procured basis.
    In March 2017, Dr. Kraemer reported that Worker was still severely depressed and that
    her untreated PTSD will complicate and delay her recovery from her pain disorder.
    D. Trial Before WCJ; WCJ’s Findings and Award; Opinion on Decision10
    A WCJ held a two-day trial in May and July 2017. The only witness was Worker,
    and her testimony focused on her sexual relationship with Dr. Massey. The evidence
    included more than 1,000 pages of medical, psychological, or medical-legal reports.
    Worker claimed eight years of TD benefits covering the period October 6, 2008, through
    October 19, 2016. XL Specialty denied her claims and provided no benefits, arguing that
    her injuries did not arise out of or in the course of her employment.
    The WCJ found that Worker sustained specific injuries on November 27, 2001,
    and in May 2005, as well as a cumulative trauma through January 15, 2008, to her neck,
    both arms, and psyche. Since there is a two-year cap on TD benefits for injuries
    occurring on or after January 1, 2008 (§ 4656, subd. (c)(2)), the WCJ awarded TD for the
    period October 6, 2008 through October 6, 2010 only, at the rate of $958.01 per week.
    And since the TD occurred more than five years after the 2001 injury, he ordered XL
    Specialty to pay the TD award.
    10
    The WCJ issued an original findings and award, an amended findings and
    award, and a second amended award to correct clerical errors in the first two awards.
    Rather than describe the changes in each award, we describe the WCJ’s ultimate findings
    and award as set forth in his second amended award.
    19
    The WCJ found that Worker was 100 percent permanently disabled for the injury
    to her psyche alone based on Dr. Sidle’s report and awarded PD at the rate of $958.0111
    per week beginning October 7, 2010, for life, subject to statutory cost-of-living
    adjustments. The WCJ awarded future medical care and $219,735.90 in attorney fees to
    Worker’s attorney.
    In his opinion on decision, the WCJ noted that the central issue was whether
    Worker’s psychiatric injury was a compensable consequence of her industrial
    musculoskeletal injuries and that both Dr. Sidle and Dr. Michaels agreed that Worker
    suffered some degree of psychiatric injury due to chronic pain from her work injuries.
    The WCJ reasoned that a significant portion of her PD was due to her improper sexual
    relationship with Dr. Massey. He found that “Dr. Massey was duly and properly
    authorized to provide treatment” and that over the course of that treatment, he “began to
    express himself in terms of sexual attraction, sometimes accompanied by intimate
    touching beyond [what] would be considered appropriate in a medical setting.”
    Dr. Massey went to Worker’s home and “made what is usually called an indecent
    proposal.” The WCJ noted that no one claimed the sexual relationship was part of the
    treatment for Worker’s industrial injuries. Thus, the question presented was whether
    Dr. Massey’s actions, which were plainly misconduct, broke the chain of industrial
    causation. The WCJ did not find any precedent on point. Based on case law regarding
    other forms of misconduct and the rule of liberal construction, he found that the chain of
    causation was not broken. He noted that cases have held that additional injuries caused
    by the negligence of the treating physician are compensable consequences of the
    treatment provided by the employer.
    11
    There was an inconsistency in the second amended findings and award
    regarding the starting weekly rate for total PD payments. In his findings of fact, the WCJ
    found that the weekly rate for permanent total disability was $1,172.57 per week. But in
    the award, he stated the weekly rate for permanent total disability was $958.01 per week.
    20
    In response to defense arguments that the PTSD was not industrial because the
    “illicit” conduct occurred in Worker’s home and not at work, the WCJ reasoned that
    “without the incidents of improper remarks and intimate touching that took place in the
    examining room, the progression from the merely offensive to the truly injurious could
    not have taken place” and held that the events that “took place during treatment were a
    proximate cause of psychiatric injury.” The WCJ found that Dr. Sidle had convincingly
    stated that the PD from the three injuries was “ ‘inextricably intertwined’ ” and “that the
    psychiatric PD was largely caused by treatment events due to all three injuries.” The
    WCJ therefore made the PD award joint and several. To avoid further delay in payments
    to Worker, he ordered Arrowood to pay the award, subject to contribution or
    reimbursement from XL Specialty.
    E. Petitions for Reconsideration by the WCAB
    All three parties petitioned for reconsideration. After the parties petitioned for
    reconsideration, the WCJ rescinded his original and his amended findings and award and
    filed the second amended findings and award that addressed some of the points raised in
    Worker’s petition for reconsideration. The parties then filed petitions for reconsideration
    challenging the second amended findings and award.12
    XL Specialty’s petition challenged the PD award, arguing that under
    section 3208.3, for a psychiatric injury to be compensable, “actual events of employment
    must be the predominant cause” of the disability and that the psychiatric PD was due
    solely to Worker’s nonindustrial relationship with Dr. Massey. It asserted her psychiatric
    injury (PTSD) was not due to any negligent treatment or intentional tort and that the
    chain of causation was broken when Worker had sex with Dr. Massey in her home.
    Alternatively, XL Specialty argued that if industrial, then Arrowood was solely
    12
    The issues raised in Worker’s petition for reconsideration were resolved below
    and are not at issue in these proceedings. We therefore shall not describe them here.
    21
    responsible for the PD, since Arrowood authorized and paid for the treatment with
    Dr. Massey. It also argued that the correct date of injury for any cumulative trauma claim
    was in 2002 (during Arrowood’s coverage) and that Dr. Feinberg’s report was not
    substantial evidence since he had not examined Worker for several years when he
    authored his last report.
    Arrowood argued that Worker’s psychiatric injuries were not related to her 2001
    injury because her psychiatric complaints worsened more than five years after the 2001
    injury and she did not amend her application for adjudication of claim to allege a
    psychiatric injury until 2011. Arrowood relied on the orthopedic experts, who opined
    that there was no new orthopedic injury or PD due to the 2001 injury. It asserted that the
    psychiatric injury that developed in 2013 (PTSD) was not a compensable consequence of
    the 2001 injury, was a separate cause of action under section 5303, and that Arrowood
    was not liable for any injury arising from Worker’s sexual contacts with Dr. Massey
    since they occurred outside the scope of treatment and Worker was never forced to treat
    with Dr. Massey. Arrowood also relied on the reports of the psychiatric experts, who had
    opined that Worker’s original psychiatric diagnoses (pain disorder, anxiety, and
    depression) were due to the cumulative trauma, not the 2001 injury. Arrowood argued
    that if the psychiatric injury was compensable, it was inappropriate to rely on Dr. Sidle’s
    reports because he did not address apportionment, relied on factors used in the 2005
    Schedule—the GAF score—and failed to evaluate the work functions required to rate
    psychiatric PD under the 1997 Rating Schedule. Arrowood asserted that it was improper
    to award 100 percent PD since Worker had not rebutted the rating in the 1997 Schedule
    and that the scheduled rating was prima facie evidence of her PD, which could only be
    rebutted as set forth in LeBoeuf v. Workers’ Comp. Appeals Bd. (1983) 
    34 Cal.3d 234
    (LeBoeuf). It argued that there was no evidence regarding her ability to compete in the
    open labor market, that it was improper for Dr. Sidle to opine on that question since he
    22
    was not a vocational expert, and that the WCJ erred in awarding 100 percent PD without
    vocational evidence. It also argued that there was no basis to order Arrowood to pay TD
    or Worker’s medical-legal expenses and that XL Specialty was responsible for those
    benefits.
    Worker’s answer argued that Dr. Massey’s conduct was both unethical and
    criminal and that the sexual conduct that occurred in his exam room was sufficient to
    subject him to criminal liability for sexual exploitation of a patient under the Business
    and Professions Code. She argued that Dr. Massey, who was treating her for all three
    injuries, made sexual overtures in his office and nurtured a vulnerability in her while she
    was overmedicated, that he controlled both her medications and her disability benefits,
    and that the investigations by BAPWC, the police, and the Medical Board caused her
    major psychological trauma.
    The WCJ’s report and recommendation on reconsideration repeated the analysis in
    his opinion on decision. He noted that Dr. Sidle had opined that Worker’s disability
    arose from Dr. Massey’s treatment for all three industrial injuries. The WCJ said the
    identity of the party authorizing and paying for the treatment and the relative contribution
    of each injury to Worker’s orthopedic PD was irrelevant. He rejected XL Specialty’s
    argument regarding the date of the cumulative trauma injury since both orthopedic
    experts found the date of the cumulative trauma injury was January 15, 2008, and there
    was evidence of further injurious exposure at work in 2006. He explained that Worker’s
    preexisting psychological stressors did not cause her PTSD, concluded that the PTSD
    alone was sufficient to support an award of 100 percent PD, and held that a report from a
    vocational expert is not required under Milpitas Unified School Dist. v. Workers’ Comp.
    Appeals Bd. (2010) 
    187 Cal.App.4th 808
     (Guzman). He recommended the WCAB grant
    reconsideration to correct an error in the amount of the weekly TD rate and to hold that
    XL Specialty alone was responsible for the TD award. Subsequently, in a supplemental
    23
    brief, Worker conceded that the correct starting rate for total PD payments was $916.33
    per week.
    The WCAB granted reconsideration in November 2017 and issued its decision
    after reconsideration in June 2019. The WCAB amended the amounts of the weekly TD
    and total PD rates, made orders regarding the attorney fees that are not at issue here, and
    affirmed the award. Arrowood and XL Specialty filed separate petitions for review
    challenging the WCAB’s decision.13 XL Specialty filed a motion to consolidate the
    petitions. We denied the motion to consolidate but ordered the petitions considered
    together for further briefing, oral argument, and disposition.14
    13
    Four documents that Petitioners submitted as exhibits to their petitions for writ
    of review were not in the certified record filed by the WCAB. The documents were:
    (1) the Stipulations with Request for Award dated June 10, 2005, and the Award filed on
    July 6, 2005; (2) Worker’s Petition to Reopen dated October 17, 2006; (3) the Stipulation
    and Award and/or Order dated January 4, 2011; and (4) the minutes of the hearing and
    summary of evidence for the second day of trial dated July 13, 2017. On our own
    motion, we considered judicially noticing these omitted documents and requested
    supplemental briefing from the parties on the propriety of taking judicial notice and the
    tenor of the matter to be judicially noticed. (Evid. Code, §§ 455, subd. (a), 459,
    subd. (c).) In its response, the WCAB explained that these documents may have been
    omitted from the record because they were filed before the WCAB instituted its
    electronic document management system or due to errors at the district office level. The
    only party to object was the WCAB. And it objected to the court taking judicial notice of
    only the second document listed above on the ground that there was insufficient indicia
    on the exhibit that it was ever filed with the WCAB. In light of this, we shall take
    judicial notice of documents 1, 3, and 4 listed above, but not document 2.
    14
    On September 10, 2020, after we denied the motion to consolidate, XL
    Specialty filed a brief in opposition to Arrowood’s petition for review. Arrowood has
    objected to the filing of this brief. Since we denied consolidation, XL Specialty is not a
    party to the writ proceeding filed by Arrowood. In addition, XL Specialty’s brief is not
    authorized by California Rules of Court, rule 8.720, or this court’s order granting review,
    and XL Specialty did not obtain leave of court to file its September 10, 2020 brief. For
    these reasons, we shall not consider it further.
    24
    IV. DISCUSSION
    A. Standard of Review
    This court is authorized to review WCAB decisions and to issue a writ of review
    but may not exercise “its independent judgment on the evidence.” (§§ 5950, 5952.) The
    WCAB’s findings on questions of fact “are conclusive and final so long as, based on the
    entire record, they are supported by substantial evidence.” (Save Mart Stores v. Workers’
    Comp. Appeals Bd. (1992) 
    3 Cal.App.4th 720
    , 723.) Its conclusions on questions of law
    are reviewed de novo and when the reviewing court is asked to interpret and apply a
    statute to undisputed facts, the review is also de novo. (Benson v. Workers’ Comp.
    Appeals Bd. (2009) 
    170 Cal.App.4th 1535
    , 1543 (Benson).)
    “Whether an industrial injury proximately causes a later injury or death within the
    meaning of section 3600 is a question of fact. [Citations.] ‘Judicial review of the
    Board’s decision on factual matters is limited to determining whether the decision, based
    on the entire record, is supported by substantial evidence.’ [Citations.] In this context,
    judicial review has been expressly limited by statute to whether the award ‘was not
    supported by substantial evidence’ and the factual findings ‘support the . . . award.’
    (§ 5952, subds. (d), (e).) Indeed, section 5952 expressly provides that ‘[n]othing in this
    section shall permit the court . . . to exercise its independent judgment on the evidence.’ ”
    (South Coast Framing, Inc. v. Workers’ Comp. Appeals Bd. (2015) 
    61 Cal.4th 291
    ,
    302-303 (South Coast).) “The WCJ’s findings of fact, and the Board’s adoption of them,
    ‘are final and conclusive and not subject to appellate review if supported by substantial
    evidence in light of the entire record. [Citations.] Substantial evidence must be
    reasonable in nature, credible, and of solid value such that a reasonable mind might
    accept it as adequate to support a conclusion. [Citation.] In examining the entire record,
    this court “may not simply isolate evidence which supports or disapproves the board’s
    25
    conclusions and ignore other relevant facts which rebut or explain the supporting
    evidence . . . .” ’ ” (Id. at p. 303.)
    B. Analysis of Contentions on Writ Review
    1. We reject XL Specialty’s assertion that the proper date of injury for the
    cumulative trauma claim was in March 2002
    XL Specialty contends the WCJ erred in finding a cumulative trauma injury in
    2008 (during its coverage) and that Arrowood is responsible for the cumulative trauma
    claim because the correct date of injury for the cumulative trauma injury was in 2002
    (during Arrowood’s coverage). XL Specialty asserts that substantial evidence supports
    finding that the date of injury for the cumulative trauma claim was in March 2002
    because Worker was temporarily disabled by her cumulative injury at that time.
    An industrial injury may be either “ ‘specific’ ” or “ ‘cumulative.’ ” (§ 3208.1.) A
    specific injury occurs “as the result of one incident or exposure which causes disability or
    need for medical treatment.” (§ 3208.1.) A cumulative injury is due to “repetitive
    mentally or physically traumatic activities extending over a period of time, the combined
    effect of which causes any disability or need for medical treatment.” (§ 3208.1.)
    Regardless of the length of the cumulative exposure—which was arguably from
    November 2001 to January 2008—liability for a cumulative trauma injury is limited by
    statute to the injured worker’s employer or employers during the one year immediately
    “preceding either the date of injury, as determined pursuant to section 5412, or the last
    date on which the employee was employed in an occupation exposing . . . her to the
    hazards of the . . . cumulative injury, whichever occurs first.” (§ 5500.5, subd. (a).)
    Section 5412 provides that the “date of injury” for cumulative trauma injuries is
    the “date upon which the employee first suffered disability therefrom” and the employee
    “either knew, or in the exercise of reasonable diligence should have known, that such
    disability was caused by . . . present or prior employment.” Thus, determining the date of
    injury in a cumulative trauma case requires “the concurrence of the date of first
    26
    compensable disability and the date of the employee’s knowledge of the injury’s
    industrial relationship. [Citation.] These elements present questions of fact to be
    determined by the [WCAB] and the burden of proving them is on the employer.
    [Citation.] In general, an employee is not charged with knowledge that his or her
    disability is job-related without medical advice to that effect.” (Newton v. Workers’
    Comp. Appeals Bd. (1993) 
    17 Cal.App.4th 147
    , 156, fn. 16 (Newton).) Disability as used
    in section 5412 means either compensable TD or PD. Medical treatment alone is not
    disability, but it may be evidence of compensable PD, as may a need for splints and
    modified work. (State Comp. Ins. Fund v. Workers’ Comp. Appeals Bd. (2004) 
    119 Cal.App.4th 998
    , 1005-1006.) The date of injury for a cumulative trauma claim may be
    months or years before the employee’s last day worked or years after the employee stops
    working. (Western Growers Ins. Co. v. Workers’ Comp. Appeals Bd. (1993) 
    16 Cal.App.4th 227
    , 239 (Western Growers) [date of cumulative trauma injury was in 1985
    even though employee continued working until 1987]; 1 Cal. Workers’ Compensation
    Practice (Cont.Ed.Bar 4th ed. 2003) § 11.52 (rev. 3/19) (hereafter Workers’ Comp.
    Practice).)
    “In any given situation, there can be more than one injury, either specific or
    cumulative or a combination of both, arising from the same event or from separate
    events. [Citations.] The number and nature of the injuries suffered are questions of fact
    for the WCJ or the WCAB. [Citations.] For example, if an employee becomes disabled,
    is off work and then returns to work only to again become disabled, there is a question of
    fact as to whether the new disability is due to the old injury or whether it is due to a new
    and separate injury.” (Western Growers, supra, 16 Cal.App.4th at p. 234.)
    The WCJ found that Worker sustained specific injuries on November 27, 2001 and
    in May 2005, and a cumulative trauma injury “during the period ending 1/15/2008,” the
    last day that she worked. XL Specialty contends the date of the cumulative trauma injury
    27
    was not Worker’s last day worked, but much earlier in March 2002, when there was a
    concurrence of disability and knowledge. Since the date of cumulative injury is a
    question of fact for the WCAB, our task is to determine, in light of the entire record,
    whether substantial evidence supports the WCJ’s and WCAB’s finding. (Newton, supra,
    17 Cal.App.4th at p. 156, fn. 16.)
    Worker’s assertion of a specific injury claim in 2001 does not bar a later
    cumulative trauma claim based on evidence of continuing exposure to injury-causing
    events at work. (Western Growers, supra, 16 Cal.App.4th at p. 234; see, e.g., Aerospace
    Corp. v. Workers’ Comp. Appeals Bd. (2016) 81 Cal.Comp.Cases 838 [writ denied;
    injured worker who claimed specific injury in 1998 also suffered cumulative injury
    ending in 2011 where there was evidence that he experienced repeated injurious
    exposures after returning to work following first injury].) The WCAB has held that the
    acceleration or aggravation of a preexisting industrial injury is compensable as a new
    separate injury, if the aggravation is reasonably attributable to the injured worker’s
    subsequent employment. (Ponce v. Barrett Business Services, Inc. (2017) 82
    Cal.Comp.Cases 786, 789 [truck driver with specific injury to shoulder returned to work
    and suffered cumulative injury to his wrist due to repeated injurious exposures after he
    adjusted the way he performed his work tasks following shoulder surgery], citing Smith v.
    Workmen’s Comp.App.Bd. (1969) 
    71 Cal.2d 588
    .)
    Here, there was ample evidence of continued exposure to injury-causing events
    after 2002 that supported the WCJ’s finding of cumulative injury through January 15,
    2008. Notably, when settling her 2001 injury, Worker and Arrowood stipulated that she
    sustained a specific injury to her neck and right arm on November 27, 2001. She did not
    suffer any disability from that injury until March 2002, when Dr. Jayakar reduced her
    work hours to four hours per day. In August 2002, her hours were increased, and in
    October 2002, the doctor released her to return to work full time, but told her to limit her
    28
    keyboard use. In November 2002, Worker was “working 8 hours per day and typically
    keyboarding between 4-6 hours per day on an intermittent basis.” Worker continued
    working. In January 2004, she returned to Dr. Jayakar. Worker said she continued to do
    her regular job but was not always able to limit her keyboarding to four hours per day.
    Since she complained of increased symptoms, Dr. Jayakar placed her back on part-time
    work. In April 2004, Dr. Jayakar released her back to full time work and again told her
    to limit her keyboarding to four hours per day. During these periods of partial temporary
    disability in 2002 and 2004, Worker received salary continuance benefits from her
    employer. Dr. Jayakar declared her injuries to her neck and right arm permanent and
    stationary in 2002 and again in April 2004.
    In May 2005, Worker complained of new symptoms in her left wrist and palm,
    due to “using her left arm more for mousing.” Applied Materials treated this as a new,
    separate injury and referred her to a different physician, Dr. Paul Ware. By that time,
    Applied Materials had changed workers’ compensation carriers and XL Specialty was
    providing the coverage. In August 2005, Worker gave a history of a gradual onset of left
    wrist, left elbow, and left upper back pain due to repeated use of her computer mouse
    over the previous six months. She was still performing her usual duties. Dr. Holmes (the
    orthopedic QME for XL Specialty’s claims) later opined that “there was a very specific
    worsening of her symptoms in 2005.” Dr. Feinberg described her condition as an
    “overuse syndrome” and opined that her condition worsened in 2005.
    In March 2006, Worker started calling in sick because of increased pain in her
    right arm and neck. On April 4, 2006, Dr. Jayakar took her off work for three weeks;
    shortly thereafter she referred her to BAPWC. Worker remained off work until January
    2007, when Dr. Gowda released her to return to work part-time. On September 13, 2007,
    Dr. Massey released her to “full-time” work, and she continued to work full time until
    she was laid off on January 15, 2008.
    29
    In summary, there is evidence that after injuring her right arm and neck in
    November 2001, Worker continued working—on at least a part-time basis and often full
    time—until March 2006, when she was first totally temporarily disabled by her injuries.
    During that over four-year period, Worker was exposed to additional injury-causing
    events, complained of new injuries to her left arm due to repeated use of her left arm for
    computer work in 2005. And except for a nine-month period of total TD in 2006, she
    continued to work and experience such exposure through January 2008. The record does
    not indicate precisely when XL Specialty took over the coverage, but it appears that
    Worker worked for at least 23 months during XL Specialty’s coverage period (from May
    2005 to March 2006 and from January 2007 to January 2008). Dr. Holmes opined that
    her physical injuries were due to prolonged cumulative exposure at work from 2001 until
    2008. Dr. Feinberg opined that any increase in her disability after the 2001 injury was
    due to ongoing cumulative trauma up to her last day of work. Thus, substantial evidence
    supports the WCJ’s finding of cumulative trauma during XL Specialty’s coverage. For
    these reasons, we reject XL Specialty’s assertion that the correct date of injury for the
    cumulative trauma was in March 2002.
    2. Industrial Causation: Worker’s psychiatric disability that arose out of her
    sexual exploitation by Dr. Massey was compensable
    Both Arrowood and XL Specialty argue that Worker’s psychiatric disability is not
    industrial, that Worker broke the chain of industrial causation when she entered into a
    personal relationship with Dr. Massey outside of the medical setting, and that her PTSD
    did not arise out of the employment because the sexual activity between Dr. Massey and
    Worker occurred in Worker’s home, did not involve medical treatment, and was
    consensual. They also argue that it would be inequitable to hold the employer liable in
    this case. Since there is no authority directly on point, the parties analogize to other types
    30
    of cases where industrial causation was at issue, including cases involving medical
    negligence in treating industrial injuries and assaults by third parties.
    Worker responds that her psychiatric disability is industrial because Dr. Massey
    treated her for her industrial injuries, controlled her medications and financial well-being,
    and kept her in an overmedicated state. She contends that the employer directed her to
    Dr. Massey, that Dr. Massey used his superior position in the doctor-patient relationship
    “to create a position of trust,” which he then violated; that both psychiatric QME’s
    opined that his conduct was inappropriate; and that the inappropriate conduct occurred
    not only in Worker’s home, but also in Dr. Massey’s clinic. She argues that the conduct
    was a form of compensable medical negligence, that both case law and statute provide
    that the doctor-patient relationship is inherently unequal, and that a patient cannot
    consent to a sexual relationship with her physician. As noted, the WCJ found the
    psychiatric injury that was due to the sexual exploitation by Dr. Massey was industrial.
    Workers’ compensation liability exists “in lieu of any other liability whatsoever”
    and “without regard to negligence” “against an employer for any injury sustained by [its]
    employees arising out of and in the course of the employment” where specified
    “conditions of compensation concur.” (§ 3600, subd. (a).) There are 10 conditions of
    compensation. At issue here are conditions 2 and 3: “(2) Where, at the time of the
    injury, the employee is performing service growing out of and incidental to his or her
    employment and is acting within the course of his or her employment. [¶] (3) Where the
    injury is proximately caused by the employment, either with or without negligence.”
    (§ 3600, subd. (a)(2), (3)).
    “ ‘ “The requirement of . . . section 3600 is twofold. On the one hand, the injury
    must occur ‘in the course of the employment.’ This concept ‘ordinarily refers to the time,
    place, and circumstances under which the injury occurs.’ [Citation.] . . .” [Citation.] [¶]
    “On the other hand, the statute requires that an injury ‘arise out of’ the employment . . . .
    31
    It has long been settled that for an injury to ‘arise out of the employment’ it must ‘occur
    by reason of a condition or incident of [the] employment. . . .’ [Citation.] That is, the
    employment and the injury must be linked in some causal fashion.” ’ ” (South Coast
    supra, 61 Cal.4th at p. 297.) The applicant for workers’ compensation benefits has the
    burden of establishing the reasonable probability of industrial causation by a
    preponderance of the evidence. (Latourette v. Workers’ Comp. Appeals Bd. (1998) 
    17 Cal.4th 644
    , 650 (Latourette).)
    Tort law and the workers’ compensation law are “significantly different” in their
    “application of causation principles.” (South Coast, supra, 61 Cal.4th at p. 297.) While
    both use the phrase “proximate cause,” “[t]ort liability only attaches if the defendant’s
    negligence was a significant or substantial factor in causing injury.” (Id. at p. 299; italics
    added.) On the other hand, “the workers’ compensation system is not based upon fault.
    ‘It seeks (1) to ensure that the cost of industrial injuries will be part of the cost of goods
    rather than a burden on society, (2) to guarantee prompt, limited compensation for an
    employee’s work injuries, regardless of fault, as an inevitable cost of production, (3) to
    spur increased industrial safety, and (4) in return, to insulate the employer from tort
    liability for [its] employees’ injuries.’ ” (South Coast, at p. 298.) “Proximate cause” in
    workers’ compensation cases has been interpreted as merely elaborating on the
    requirement that the injury arise out of the employment. “ ‘ “ ‘All that is required is that
    the employment be one of the contributing causes without which the injury would not
    have occurred.’ ” ’ ” (Id. at pp. 297-298.) The proximate cause language in section 3600
    is “ ‘less restrictive than that used in tort law, because of the statutory policy . . . favoring
    awards of employee benefits.’ ” (South Coast, at p. 298; Latourette, supra, 17 Cal.4th at
    p. 651 [in applying § 3600, the court must be guided by the “ ‘fundamental principle that
    the requirement is to be liberally construed in favor of awarding benefits’ ”].)
    32
    “[W]orkers’ compensation liability may . . . encompass a subsequent nonindustrial
    injury . . . attributable to the initial industrial accident.” (South Coast, supra, 61 Cal.4th
    at p. 297.) It has long been the rule that “the aggravation of an industrial injury or the
    infliction of a new injury resulting from its treatment or examination are compensable
    under the [Workers’ Compensation Act] and, therefore, within the exclusive cognizance
    of the [WCAB].” (Fitzpatrick v. Fidelity & Casualty Co. (1936) 
    7 Cal.2d 230
    , 232.) As
    the Supreme Court explained in South Coast, “industrial causation has been shown in an
    array of scenarios where a work injury contributes to a subsequent nonindustrial injury.
    An employee is entitled to compensation if a new or aggravated injury results from
    medical or surgical treatment for an industrial injury. ([Citation]; Georgia Casualty Co.
    v. Indus. Acc. Com. (1927) 
    87 Cal.App. 333
    , 334-335 . . . [death from anesthetic]; see
    Maher [v. Workers’ Comp. Appeals Bd. (1983) 
    33 Cal.3d 729
    ,] 735-738 [adverse drug
    reaction when treatment was required for employment]; Ballard v. Workmen’s
    Comp.App.Bd. (1971) 
    3 Cal.3d 832
    , 837-839 . . . [drug addiction to prescribed pain
    medication].) Causation may also be shown if an industrial injury contributes to a later
    nonindustrial accident or injury. (See Lundberg v. Workmen’s Comp.App.Bd. (1968) 
    69 Cal.2d 436
    , 439-441 . . . [industrial back injury contributed to later ruptured disc];
    Ferreira v. Workmen’s Comp. Appeals Bd. (1974) 
    38 Cal.App.3d 120
    , 124-126 . . .
    [hernia suffered at work contributed to later hernia suffered at home]; State Comp. Ins.
    Fund v. Ind. Acc. Com. (1959) 
    176 Cal.App.2d 10
    , 13-21 . . . [carpenter’s industrial eye
    injury contributed to later nonindustrial accident while using a saw at home].) Indeed,
    even a worker’s suicide may be compensable if an industrial injury contributed to it.
    [Citations.]” (South Coast, at p. 300.) In South Coast, the court held that an injured
    worker’s death from respiratory failure at home was industrial because medications he
    took for an industrial injury were a contributing cause of death where the QME testified
    33
    that those medications played a small role in causation: more than 0 percent but less than
    20 percent. (Ibid.)
    An employee is entitled to compensation for a new or aggravated injury that
    results from the medical treatment of an industrial injury, whether the doctor was
    furnished by the employer, the insurance carrier, or was selected by the employee.
    (Hikida v. Workers’ Comp. Appeals Bd. (2017) 
    12 Cal.App.5th 1249
    , 1262 (Hikida)
    citing Fitzpatrick v. Fidelity & Casualty Co., 
    supra,
     7 Cal.2d at p. 232.) “Aggravation of
    the original injury by medical treatment is considered ‘a foreseeable consequence of the
    original compensable injury, compensable within the workers’ compensation proceeding
    and not the proper subject of an independent common law damage proceeding against the
    employer.’ ” (Hikida, at p. 1261.) This rule derived “from (1) the concern that applying
    apportionment principles to medical care would delay and potentially prevent an injured
    employee from getting medical care, and (2) the fundamental proposition that workers’
    compensation should cover all claims between the employee and employer arising from
    work-related injuries, leaving no potential for an independent suit for negligence against
    the employer.” (Id. at p. 1263.) In Hikida, the court concluded that the injured worker’s
    chronic regional pain syndrome (CRPS) that was the result of a failed surgery for her
    industrial carpal tunnel syndrome, was industrial and awarded permanent total disability
    based on the CRPS. (Id. at p. 1262.)
    Petitioners argue that this theory of causation does not apply since it was
    undisputed that the sexual conduct was not medical treatment, the sexual relationship was
    consensual, and the sex acts occurred in Worker’s home. Worker responds that her
    treatment was a contributing cause of her PTSD because Dr. Massey prescribed excessive
    amounts of medication, which made it difficult for her to resist his advances; he was in a
    superior position in the doctor-patient relationship and controlled both her treatment and
    34
    disability benefits; and he made sexual advances in his exam room that groomed her for
    the sexual exploitation that occurred in her home.
    Based on our review of the record, we conclude that Worker met her burden of
    demonstrating that her PTSD was a new injury that resulted from the treatment for her
    industrial injuries and that her employment was one of the contributing causes without
    which the sexual exploitation by Dr. Massey and her PTSD would not have occurred.
    Multiple QME’s reported for years that Worker was overmedicated, which affected her
    ability to function, and Dr. Massey was prescribing five or six drugs at the time of their
    sexual contact. In early 2013, about the time that Dr. Massey started making
    inappropriate sexual comments to Worker, Dr. Sidle reported that she was in a very
    vulnerable state and urgently needed inpatient psychiatric treatment. Dr. Sidle concluded
    that Worker’s PTSD, which was due to her sexual exploitation by Dr. Massey, was
    “100% industrial” because Dr. Massey was treating her physical, accepted industrial
    injuries. Dr. Jayakar referred Worker to BAPWC for treatment of her industrial injuries
    and Dr. Massey took over that treatment in 2007. By the time the sexual exploitation
    occurred, Dr. Massey had been treating her industrial injuries for six years, and
    Arrowood and Worker had stipulated that he would continue to treat her industrial
    injuries and that Arrowood would continue to authorize all reasonable requests for
    medical treatment. Dr. Sidle opined that having a sexual relationship with a patient is
    illegal, unethical, and below the standard of care because it abuses the power relationship
    between doctor and patient and takes advantage of a vulnerability, especially in a patient
    like Worker who was overmedicated and already feeling bad about herself. These facts
    support the conclusion that the medication and treatment provided for Worker’s industrial
    injuries was a contributing cause of Worker’s PTSD and disability.
    XL Specialty argues that Worker’s PTSD is not industrial because, unlike cases
    described in South Coast, it is not the result of negligent medical treatment. To prove
    35
    professional negligence, the patient must demonstrate that the treatment fell below the
    standard of care. (Turpin v. Sortini (1982) 
    31 Cal.3d 220
    , 229 [elements of cause of
    action for professional negligence].) Dr. Sidle testified that it was below the standard of
    care for a physician to have sex with a patient because it abuses the power relationship
    between doctor and patient and takes advantage of a vulnerability. The WCJ reasoned
    that Dr. Massey had a duty of care to Worker as her treating physician and that he
    breached that duty of care by using his position as her physician, together with the
    diminished capacity brought about by her medication, to induce her to engage in
    otherwise unwanted sexual relations. The WCJ reasoned that that breach of duty caused
    harm and that since Worker’s psychiatric disability was caused in part by Dr. Massey’s
    negligence, it was compensable. We conclude the evidence outlined above is substantial
    evidence that supports the WCJ’s conclusions.
    XL Specialty cites Atienza v. Taub (1987) 
    194 Cal.App.3d 388
    , which held that a
    patient could not maintain a civil action for medical malpractice against her doctor based
    on alleged sexual misconduct unless the doctor initiated the sexual relationship under the
    guise of medical treatment. XL Specialty’s reliance on Atienza is misplaced. In 1993—
    after Atienza was decided and long before the conduct at issue here—the Legislature
    enacted Business and Professions Code section 729, which provides that certain health
    care providers, including physicians, who engage in “sexual intercourse . . . or sexual
    contact with a patient” are guilty of the criminal offense of “[s]exual exploitation,” which
    is punishable as a misdemeanor or a felony depending on the number of acts or victims.
    (Bus. & Prof. Code, § 729, subds. (a) & (b).) The patient’s consent is not a defense. (Id.,
    subd. (b).) The statute also provides that a physician “shall not be guilty of sexual
    exploitation for touching any intimate part of a patient . . . unless the touching is outside
    the scope of medical examination and treatment, or . . . is done for sexual gratification.”
    (Ibid.) It was undisputed that the sexual contact here was outside the scope of medical
    36
    treatment and done for Dr. Massey’s sexual gratification. The statute defines “sexual
    contact” as “sexual intercourse or the touching of an intimate part of a patient for the
    purpose of sexual arousal, gratification, or abuse.” (Bus. & Prof. Code, § 729,
    subd. (c)(3).) Under the common law doctrine of negligence per se, Business and
    Professions Code section 729 may be used to establish duties and standards of care in a
    negligence action. (Elsner v. Uveges (2004) 
    34 Cal.4th 915
    , 927.)
    Petitioners argue that Worker’s PTSD was not compensable because it was the
    result of a consensual sexual relationship that occurred in Worker’s home and not at her
    workplace or Dr. Massey’s clinic. Contrary to Petitioners’ arguments, under Business
    and Profession Code section 729, subdivision (b), consent is not a defense. Thus, it is
    irrelevant whether Worker consented. In addition, the sexual exploitation was not limited
    to Worker’s home. Under the statutory definition of “sexual contact,” which includes
    “the touching of an intimate part of a patient for the purpose of sexual arousal,
    gratification, or abuse” (Bus. & Prof. Code, § 729, subd. (c)(3)), the sexual touching that
    occurred at BAPWC while Dr. Massey was treating her is a form of sexual exploitation.15
    XL Specialty’s reliance on Atascadero Unified School District v. Workers’ Comp.
    Appeals Bd. (2002) 
    98 Cal.App.4th 880
     is misplaced. In that case, the court held that
    there was an insufficient causal nexus between an alleged psychiatric injury that arose
    from workplace gossip about the employee’s extramarital affair with a coworker to
    support a finding of industrial causation merely because the gossip occurred at work.
    The court reasoned that “gossip about an employee’s personal life is not part of the
    employee-employer relationship,” that the “off-duty affair had nothing to do with her
    employment,” and that even though the gossip occurred at work, “the nature of her duties
    was not the proximate cause of her injury for it merely provided a stage for the event.”
    15
    Our conclusion is limited to whether Worker has met her burden of
    demonstrating a sufficient causal connection for the purpose of demonstrating causation
    under the workers’ compensation laws.
    37
    (Id. at p. 885.) Thus, the court held that “the employment was not a contributory cause of
    the injury.” (Ibid.) Atascadero is factually distinguishable since it did not involve a
    compensable consequence injury that was the result of medical treatment provided by the
    employer.
    Petitioners argue that the PTSD is not compensable because Dr. Massey’s conduct
    was deliberate and intentional. They analogize to industrial injuries arising out of
    assaults by third parties. “[W]hether an assault at the hands of a third person” arises out
    of the employment “depends upon ‘whether the assault is . . . made by reason of
    circumstances connected with the employment or without any relation thereto.’ ”
    (Western Airlines, supra, 155 Cal.App.3d at p. 369; id. at p. 371 [psychiatric injury
    caused by rape of flight attendant on a layover was nonindustrial because there was no
    evidence her employment contributed in any way to her selection as the victim].) Worker
    presented substantial evidence that her sexual exploitation by Dr. Massey was connected
    to her employment and that her employment was a contributing cause under Western
    Airlines. She was assaulted by the physician who was treating her industrial injuries;
    who was a member of her employer’s MPN; and whose treatment was authorized and
    paid for by Arrowood, subjected to utilization review by the employer, and should have
    been authorized by XL Specialty to treat her industrial injuries.
    Since we conclude that the disability due to Dr. Massey’s sexual exploitation is
    compensable as a consequence of the medical treatment provided by the employer or as
    an employment-related assault by a third party, we shall not address Petitioners’ other
    causation arguments.
    3. XL Specialty is jointly and severally liable for the PD caused by the sexual
    exploitation by Dr. Massey
    XL Specialty argues that if Worker’s disability is compensable, it is due to the
    2001 injury and Arrowood is solely liable because it provided the treatment and XL
    38
    Specialty did not authorize or pay for any treatment at BAPWC. Thus, XL Specialty
    seeks to overturn the WCAB’s finding of joint and several liability.
    XL Specialty cannot escape liability by simply denying the claim and refusing to
    pay benefits. As noted, there is substantial evidence of injury-causing events and new
    injuries during XL Specialty’s coverage. Dr. Sidle, the psychiatric QME for the
    cumulative trauma claim, opined repeatedly (in 2011, 2013, and 2015) that the
    predominant cause of the psychiatric injury for which Worker was treated at BAPWC
    was the cumulative trauma and that her psychiatric injury was a compensable
    consequence of her physical injuries due to the cumulative trauma ending in 2008.
    Dr. Michaels (the psychiatric QME for the 2001 injury) agreed that the psychiatric injury
    was most likely due to cumulative trauma through 2008, and Dr. Holmes (the orthopedic
    QME for the cumulative trauma claim) opined that the injuries to Worker’s neck and
    arms were due to a prolonged cumulative trauma ending in 2008. Worker was treated at
    BAPWC from August 2006 until December 2013, which was after she complained of
    new injuries in 2005, and the majority of the treatment by Dr. Massey occurred after she
    stopped working in 2008. Although Arrowood authorized the treatment, the record
    supports the conclusion that some, if not most, of the treatment at BAPWC was for the
    2005 and 2008 injuries. There is no merit to XL Specialty’s argument that it cannot be
    held jointly and severally liable for Worker’s PD.
    4. XL Specialty’s challenges to Dr. Feinberg’s reports lack merit
    XL Specialty challenges the finding of injury during its policy period, arguing that
    the opinions of orthopedic AME Dr. Feinberg on causation, which the WCJ found
    definitive, are not substantial evidence because although Dr. Feinberg examined Worker
    in 2006 and 2011, he did not reexamine her when he prepared two supplemental reports
    in 2017. XL Specialty also argues that Dr. Feinberg did not have a complete medical file
    in 2017.
    39
    There is no merit to these challenges. When Dr. Feinberg examined Worker in
    2011, he reviewed 10 inches of medical records dating from 1989 to 2011. His summary
    of those records was 22 pages long. In 2011, he opined regarding causation. Initially, he
    said her upper body condition was “partially related to the 2001 injury and partially due
    to cumulative trauma until her last day of work.” He later stated he did not disagree with
    Dr. Holmes (the QME for XL Specialty’s claims), who found that her physical injuries
    were due to cumulative trauma between 2001 and 2008. By 2011, Worker had not
    worked for three years and Dr. Feinberg had all the information he needed to opine
    regarding causation. It is true that Dr. Feinberg did not reexamine Worker when he wrote
    two supplemental reports in 2017, but contrary to XL Specialty’s assertion, Dr. Feinberg
    did review another 2.5 inches of medical records in 2017. Although he rendered new
    opinions regarding PD and apportionment in 2017, he did not render any new opinions
    about the cause of her orthopedic injuries. Thus, the fact that he did not reexamine
    Worker in 2017 did not render his opinions on causation insubstantial.
    5. Substantial evidence supports the WCAB’s finding of psychiatric injury
    due to the 2001 injury
    Arrowood argues that the facts do not support a finding of psychiatric injury due
    to the 2001 injury. We disagree.
    The first mention of any injury to the psyche was in mid-2006 when Worker told
    an orthopedic surgeon she consulted that she was depressed secondary to her physical
    injuries, Dr. Garavanian (a psychologist) diagnosed a pain disorder, and Dr. Gowda
    diagnosed depression. This was months before Worker filed her petition for new and
    further disability due to the 2001 injury. Years later, in 2011—long before the sexual
    exploitation by Dr. Massey—both psychiatric experts agreed that Worker’s pain disorder,
    depression, and anxiety that were consequences of her physical injuries were due to the
    cumulative trauma, not the 2001 injury. At that time, since XL Specialty was the carrier
    40
    for the cumulative trauma claim, the record supported a conclusion that XL Specialty was
    solely responsible for the psychiatric injuries that were a compensable consequence of
    her physical injuries. (§ 5500.5.)
    But the nature of Worker’s psychiatric injury claim changed after Dr. Kraemer
    diagnosed PTSD in 2014. The psychiatric injury changed from being a compensable
    consequence of Worker’s physical injuries to being a compensable consequence of the
    sexual exploitation by her doctor, which we have concluded is compensable. Dr. Sidle
    ultimately opined that her PD was due entirely to the PTSD, which was due entirely to
    her sexual exploitation by Dr. Massey. Since Dr. Massey treated Worker for all three
    injuries, Dr. Sidle opined that the cause of her PD was inextricably intertwined between
    all of her dates of injury so that it would be difficult, if not impossible, to say what
    portion of her psychiatric disability was due to which injury. The record suggests
    Arrowood, not XL Specialty, authorized the treatment with BAPWC starting in 2006. In
    2011, Arrowood stipulated that it would continue to provide medical treatment with
    Dr. Massey as the primary treating physician. Although Arrowood argues that Worker
    could have changed doctors when it established an MPN in 2012, it also admits that
    Dr. Massey was in its MPN. In light of the entire record, these facts constitute substantial
    evidence which support the WCJ’s finding that Worker’s psychiatric PD “was largely
    caused by treatment events due to all three injuries,” which include the treatment
    Arrowood provided for the 2001 injury.
    6. Substantial evidence supports the WCAB’s finding of new and further
    disability within five years of the 2001 injury
    Arrowood argues that Worker did not suffer any new and further disability from
    her 2001 injury, including psychiatric injury, because her alleged new and further
    disability arose more than five years after November 27, 2001, the date of injury for its
    claim. Arrowood’s petition does not distinguish between the depression and anxiety that
    41
    were compensable consequences of Worker’s physical injuries (for which she received
    treatment before November 27, 2006) and the PTSD that was a compensable
    consequence of her sexual exploitation by Dr. Massey (which arose in 2013). It argues
    simply that the WCJ erred in finding that the 2001 injury caused new and further injury,
    including injury to her psyche.16 Arrowood acknowledges that Worker filed a timely
    petition to reopen but argues, correctly, that in addition to filing a timely petition, she
    must have sustained new and further disability within the five-year limitations period.
    (Sarabi v. Workers’ Comp. Appeals Bd. (2007) 
    151 Cal.App.4th 920
    , 925 (Sarabi).)
    Citing the reports of Dr. Feinberg (the orthopedic AME for the 2001 claim) and
    Dr. Holmes (the orthopedic QME for the cumulative trauma claim), Arrowood argues
    that there was no evidence of any new and further disability due to the 2001 injury, and
    that any new orthopedic disability was due to the cumulative trauma covered by XL
    Specialty. Arrowood asserts that Worker was first treated for her depression in 2008 and
    did not “allege a psychiatric injury as a compensable consequence until 2011.”
    Two statutes govern petitions to reopen. First, under section 5410, “an injured
    worker who has previously received workers’ compensation benefits either voluntarily
    paid by the employer or pursuant to an award is entitled to claim benefits for ‘new and
    further disability’ within five years of the date of injury.” (Sarabi, supra, 151
    Cal.App.4th at p. 925, italics added.) Second, “[s]ection 5803 permits the reopening of a
    previously adjudicated case for ‘good cause’ upon a petition filed by [any] party, also
    16
    At oral argument, Arrowood argued for the first time in this proceeding that it
    was not liable for Worker’s PTSD claim, as distinguished from her claim of general
    injury to her psyche, because it arose more than five years after the 2001 injury. “We do
    not consider arguments that are raised for the first time at oral argument.” (Haight
    Ashbury Free Clinics, Inc. v. Happening House Ventures (2010) 
    184 Cal.App.4th 1539
    ,
    1554, fn. 9.) Since Arrowood did not raise this point in its briefing in this court, it has
    been forfeited. (Julian v. Hartford Underwriters Ins. Co. (2005) 
    35 Cal.4th 747
    , 761
    [issues not properly addressed in the opening brief will be disregarded].)
    42
    within five years from the date of injury. If a petition to reopen under either section is
    filed within the five-year period, the [WCAB] has jurisdiction to decide the matter
    beyond the five-year period.” (Ibid., italics added.)
    To recover additional benefits, the injured worker must not only file a timely
    petition to reopen but must also have suffered a “new and further disability” within that
    five-year period, unless there is otherwise “good cause” to reopen the prior award.
    (Sarabi, supra, 151 Cal.App.4th at p. 926.) An injured worker cannot confer jurisdiction
    on the WCAB by filing a petition to reopen before the five-year period has expired for
    anticipated new and further disability that may occur after the five-year limitation period
    has run. (Ibid.) “New and further disability” means disability resulting from some
    demonstrable change in the employee’s condition, including a gradual increase in
    disability, a recurrence of TD, a new need for medical treatment, or the change of a
    temporary disability into a permanent disability. (Ibid.)
    Arrowood’s assertions ignore the timeline and substantial medical evidence that
    supports the WCJ’s finding of new and further disability, including psychiatric disability,
    prior to November 27, 2006 (the five-year anniversary of Worker’s 2001 injury). Worker
    claimed physical injuries in 2005 that overlapped her 2001 injury claim. She saw at least
    eight doctors between May 2005 and November 2006. Contrary to Arrowood’s assertion
    that Worker first treated for her depression in 2008, there was substantial evidence of “a
    new need for medical treatment” before November 27, 2006, including treatment for
    injuries to Worker’s psyche, that satisfied the definition of new and further disability in
    Sarabi, supra, 151 Cal.App.4th at page 926. Dr. Fujimoto referred her to a psychologist
    for pain management in March 2006. In April 2006, Worker complained to a consulting
    orthopedist that she was depressed secondary to her industrial injuries. Dr. Garavanian
    diagnosed a psychological pain disorder and a sleep disorder in July 2006, and
    Dr. Gowda requested authorization to treat her depression in August 2006. In September
    43
    2006, Dr. Gowda prescribed medication for her severe anxiety and referred Worker to
    Dr. Garavanian for psychotherapy follow-up. On November 2, 2006, Worker told
    Dr. Gowda that her anxiety was so high that her medication “was not covering her
    anxiety symptoms” and she could not continue in her first attempt at the functional
    restoration program. Arrowood authorized and voluntarily paid for the treatment
    described above pursuant to the open medical award on the 2001 claim. Based on this
    record, Worker met her burden of demonstrating that she suffered a new need for medical
    treatment, including treatment for injury to her psyche, before November 27, 2006. This
    was substantial evidence that supported the WCJ’s finding of new and further disability
    from the 2001 injury.
    7. The 2005 Schedule applies to PD based on psychiatric injury arising out of
    the 2001 injury claim
    Arrowood contends that Dr. Sidle’s reports are not substantial evidence of PD
    with regard to the 2001 injury because the 1997 Schedule applies to the 2001 injury claim
    and Dr. Sidle evaluated Worker’s PD according to the GAF scale in the 2005 Schedule
    and did not evaluate her impairment of eight work functions as required to rate
    psychiatric PD under the 1997 Schedule.17
    17
    The eight work functions included: “1. Ability to comprehend and follow
    instructions. [¶] 2. Ability to perform simple and repetitive tasks. [¶] 3. Ability to
    maintain a work pace appropriate to a given work load. [¶] 4. Ability to perform
    complex and varied tasks. [¶] 5. Ability to relate to other people beyond giving and
    receiving instructions. [¶] 6. Ability to influence people. [¶] 7. Ability to make
    generalizations, evaluations or decisions without immediate supervision. [¶] 8. Ability
    to accept and carry out responsibility for direction, control and planning.” (1997
    Schedule, p. 2-3.) The 1997 Schedule directed the physician to rate the level of
    impairment for each work function as “Minimal,” “Very Slight,” “Slight,” “Slight to
    Moderate,” “Moderate,” “Moderate to Severe,” or “Severe.” (Ibid.) It also contained a
    chart for converting the impairment ratings to a percentage of disability and instructions
    for rating psychiatric PD depending on the number and type of work function
    impairments. (Ibid.)
    44
    “Section 4660 prescribes the method for determining the percentages of permanent
    disability for workers’ compensation purposes” (Chang v. Workers’ Comp. Appeals Bd.
    (2007) 
    153 Cal.App.4th 750
    , 753 (Chang)) for “injuries occurring before January 1,
    2013” (§ 4660). It currently provides in part: “In determining the percentages of
    permanent disability, account shall be taken of the nature of the physical injury or
    disfigurement, the occupation of the injured employee, and his or her age at the time of
    the injury, consideration being given to an employee’s diminished future earning
    capacity.” (§ 4660, subd. (a).) “A schedule for assessing permanent disability had been
    required since 1937.” (Guzman, supra, 187 Cal.App.4th at p. 818.) The schedule has
    been updated periodically by the administrative director of the Department of Industrial
    Relations, Division of Workers’ Compensation (Administrative Director), most recently
    in 1997 and 2005.
    In 2004, the Legislature enacted comprehensive reforms of the workers’
    compensation laws with the passage of Senate Bill No. 899 (Senate Bill 899). (Stats.
    2004, ch. 34, effective Apr. 19, 2004; Brodie v. Workers’ Comp. Appeals Bd. (2007) 
    40 Cal.4th 1313
    , 1323 (Brodie).) Senate Bill 899 was an urgency measure “designed to
    alleviate a perceived crisis in skyrocketing workers’ compensation costs.” (Brodie, at
    p. 1329.) As part of its 2004 reform package, the Legislature amended section 4660.
    (Stats. 2004, ch. 34, § 32.)
    Among other things, the 2004 amendment made a major change to the system
    used to describe the “nature” of the injured worker’s “physical injury or disfigurement”
    (§ 4660, subd. (a)). The amendment discontinued the use of the systems described in the
    1997 Schedule and previous schedules for evaluating permanent impairments and
    mandated the use of “the descriptions and measurements of physical impairments and the
    corresponding percentages of impairments published in the American Medical
    Association . . . Guides to the Evaluation of Permanent Impairment (5th Edition)”
    45
    (hereafter Guides). (§ 4660, subd. (b)(1).) The Legislature also directed the
    Administrative Director to amend the PD rating schedule and to adopt regulations to
    implement the changes made to section 4660 by Senate Bill 899. (§ 4660, subds. (b)(2),
    (c), (e).) In accordance with that mandate, the Administrative Director promulgated the
    2005 Schedule. As Arrowood notes, the 2005 Schedule also changed the standards used
    to evaluate psychiatric disability. One appellate court has described the 2005 Schedule as
    a “formal administrative rule” implementing the requirements of section 4660.
    (Fitzpatrick, supra, 27 Cal.App.5th at p. 619; see also Cal. Code. Regs., tit. 8, § 9805.)
    Subdivision (d) of section 4660 (hereafter 4660(d)), as amended by Senate Bill
    899, provides that the 2005 Schedule “shall promote consistency, uniformity, and
    objectivity.” It also states that the 2005 Schedule “shall apply prospectively and shall
    apply to and govern only those permanent disabilities that result from compensable
    injuries received or occurring on and after the effective date of the adoption of the
    schedule . . . ,” which was January 1, 2005. (§ 4660(d); Guzman, supra, 187 Cal.App.4th
    at p. 818 [effective date].)
    As for claims that were still pending when the new schedule went into effect, the
    final sentence in section 4660(d) provides that “[f]or compensable claims arising before
    January 1, 2005,” the 2005 Schedule “shall apply to the determination of permanent
    disabilities when there has been either no comprehensive medical-legal report or no
    report by a treating physician indicating the existence of permanent disability, or when
    the employer is not required to provide the notice required by Section 4061 to the injured
    worker.” This language has been interpreted as creating three exceptions to the
    prospective application of the 2005 Schedule: (1) when there has been no comprehensive
    medical-legal report indicating the existence of PD; (2) when there has been no report by
    a treating physician indicating the existence of PD; or (3) when the employer is not
    required to provide the notice required by section 4061. When any of the three
    46
    circumstances described in the final sentence of section 4660(d) have occurred before
    January 1, 2005, “ ‘the percentage of permanent disability will be calculated using the
    earlier schedule that was in effect on the date of the injury.’ ” (Genlyte Group, LLC v.
    Workers’ Comp. Appeals Bd. (2008) 
    158 Cal.App.4th 705
    , 716 (Genlyte); Chang, supra,
    153 Cal.App.4th at p. 753 [2005 Schedule applies to pending matters regardless of date
    of injury unless one of the exceptions in § 4660(d) applies].)
    Arrowood does not contend that the exception for the section 4061 notice18 applies
    here and the record contains no evidence on the question whether such notice was
    required or given in this case. Arrowood relies instead on the other exceptions in
    section 4660(d). It argues that the 1997 Schedule applies because Dr. Jayakar—who was
    the treating physician—prepared reports indicating the existence of PD to Worker’s neck
    and right arm from the 2001 injury in comprehensive medical-legal reports in November
    2002 and April 2004, which were written prior to January 1, 2005.
    Worker does not respond to this argument. The WCJ did not address this
    contention directly. In his report and recommendation on reconsideration, he stated:
    “Since the legal definition of [permanent total disability] remained the same for both
    schedules, the lack of any ‘old schedule’ analysis [in Dr. Sidle’s report] is irrelevant” and
    rejected Arrowood’s sufficiency of the evidence argument. The WCAB adopted and
    incorporated the WCJ’s report as its decision.
    The difficulty with Arrowood’s argument is that the PD award here was based
    solely on the injury to Worker’s psyche, not her orthopedic injuries. Dr. Jayakar’s 2002
    18
    Section 4061, which pertains to the third (notice) exception for pre-January 1,
    2005 claims in section 4660(d), “requires notice by the employer together with the last
    payment of temporary disability indemnity that (i) no permanent disability indemnity is
    payable, (ii) the amount that is payable or (iii) ‘that permanent disability indemnity may
    be or is payable, but that the amount cannot be determined because the employee’s
    medical condition is not yet permanent and stationary.’ ” (Genlyte, supra, 158
    Cal.App.4th at p. 720.)
    47
    and 2004 reports did not report any injury to Worker’s psyche or indicate the existence of
    any psychiatric PD. In fact, there was no psychiatric injury prior to January 1, 2005. As
    we have explained, the first report of any psychiatric injury was in 2006. The first report
    that could possibly be construed as “indicating the existence of permanent disability”
    (§ 4660(d)) to the psyche was Dr. Sidle’s May 2011 report, which was written more than
    six years after the effective date of the 2005 Schedule. In addition, Dr. Sidle reported
    that Worker’s psychiatric PD was due to her PTSD, which was due to her sexual
    exploitation by Dr. Massey in 2013.
    Arrowood does not cite any cases that address the situation presented here. Our
    research has disclosed one WCAB case that addressed the application of the 1997
    Schedule where there have been multiple injuries, only one of which triggers the
    exception in section 4660(d). The injured worker in New United Motor Manufacturing,
    Inc. v. Workers’ Comp. Appeals Bd. (2007) 72 Cal.Comp.Cases 1678 (NUMMI) claimed
    cumulative injuries to his low back and hearing through November 2002. He continued
    working. He later amended his application to add cumulative injuries to both upper
    extremities and shoulders and alleged a new cumulative injury to the same body parts
    through September 2004. In April 2004, his treating physician had found that his low
    back injury alone was permanent and stationary and prepared a comprehensive
    medical-legal report describing the PD to the low back. The parties later agreed to use an
    AME. (Id. at p. 1679.) In 2006, the AME opined that there was only one cumulative
    trauma through the employee’s last day worked in November 2004 and provided a
    comprehensive report describing the PD to all body parts alleged. (Id. at pp. 1679, 1681.)
    The WCJ found that the 1997 Schedule applied, reasoning that the treating physician’s
    comprehensive medical-legal report in April 2004 “ ‘describing the factors of permanent
    disability to one of the body parts . . . was sufficient to trigger’ ” one of the exceptions in
    section 4660(d) “ ‘warranting use of the old schedule.’ ” (NUMMI, at p. 1681.)
    48
    The WCJ also relied on the fact that there was but one cumulative injury claim alleging
    injury to multiple body parts. (Ibid.)
    In our view, this case is distinguishable from NUMMI. The PD awarded here is
    based entirely on a compensable consequence injury that occurred after January 1, 2005.
    Section 4660(d) provides that the 2005 Schedule “shall apply to and govern only those
    permanent disabilities that result from compensable injuries received or occurring on and
    after the effective date of the adoption of the” 2005 Schedule. In this case, Worker’s
    compensable consequence psychiatric injuries occurred after January 1, 2005 and the
    qualifying medical reports indicating the existence of the PD from those injuries were
    made after 2005.
    The reforms in Senate Bill 899 “were enacted as urgency legislation to drastically
    reduce the cost of workers’ compensation insurance, and the Legislature intended that the
    majority of the changes go into effect as soon as possible. [Citations.] The adoption of a
    new permanent disability rating scale was part of this scheme. The purpose of the reform
    package is not served by an interpretation of section 4660, subdivision (d), that delays the
    implementation of the new rating scale based on medical-legal reports that give no
    indication of permanent disability, and indeed, may have nothing to do with that subject.”
    (Costco   Wholesale Corp. v. Workers’ Comp. Appeals Bd. (2007) 
    151 Cal.App.4th 148
    ,
    155.) We conclude that in the unique circumstances of this case, to require use of the
    1997 Schedule based on Dr. Jayakar’s reports from 2002 and 2004, which did not
    indicate the existence of any injury to Worker’s psyche, much less the existence of any
    psychiatric PD, “would violate the Legislature’s intent to bring as many cases as possible
    under the new workers’ compensation law.” (Zenith Ins. Co. v. Workers’ Comp. Appeals
    Bd. (2007) 
    153 Cal.App.4th 461
    , 465.) For these reasons, we reject Arrowood’s
    contention that Dr. Sidle’s report was not substantial evidence because he described her
    49
    psychiatric PD according to the GAF scale in the 2005 Schedule and failed to describe
    her psychiatric PD according to the work functions in the 1997 Schedule.
    8. The WCAB erred in awarding 100 percent PD
    Arrowood argues that the WCAB erred in affirming the WCJ’s award of 100
    percent PD because: (1) Dr. Sidle opined that Worker’s score on the GAF scale used to
    rate psychiatric disabilities under the 2005 Schedule was 45, which translates to a whole
    person impairment (WPI) of 40 percent and a PD rating of 70 percent after adjustment for
    diminished earning capacity, occupation, and age; (2) Dr. Sidle’s testimony was
    insufficient to rebut the scheduled rating; and (3) Dr. Sidle was not qualified to opine that
    Worker could not compete in the labor market since he was not a vocational expert. We
    agree.
    “The panoply of benefits [California’s workers’ compensation system] provides
    includes compensation for permanent disability. ‘[P]ermanent disability is understood as
    “the irreversible residual of an injury.” ’ [Citations.] ‘A permanent disability is one
    “. . . which causes impairment of earning capacity, impairment of the normal use of a
    member, or a competitive handicap in the open labor market.” ’ [Citation.] Thus,
    permanent disability payments are intended to compensate workers for both physical loss
    and the loss of some or all of their future earning capacity.” (Brodie, supra, 40 Cal.4th at
    p. 1320.)
    When Worker was first injured in 2001, former section 4660 provided in relevant
    part: “(a) In determining the percentages of permanent disability, account shall be taken
    of the nature of the physical injury or disfigurement, the occupation of the injured
    employee, and his age at the time of such injury, consideration being given to the
    diminished ability of such injured employee to compete in an open labor market.”
    (Italics added.) As amended in 2004, subdivision (a) of section 4660 provides:
    “(a) In determining the percentages of permanent disability, account shall be taken of the
    50
    nature of the physical injury or disfigurement, the occupation of the injured employee,
    and his or her age at the time of the injury, consideration being given to an employee’s
    diminished future earning capacity.” (Italics added.) In Ogilvie v. Workers’ Comp.
    Appeals Bd. (2011) 
    197 Cal.App.4th 1262
    , 1272 (Ogilvie), the court held that “the terms
    ‘diminished future earning capacity’ and ‘ability to compete in an open labor market’
    suggest . . . no meaningful difference, and nothing in Senate Bill No. 899 suggests that
    the Legislature intended to alter the purpose of an award of permanent disability through
    this change of phrase.”
    The process for calculating a PD rating under section 4660 and the 2005 Schedule
    consists of multiple steps, which are expressed in a rating “formula” that considers each
    of the factors listed in section 4660, subdivision (a). (Fitzpatrick, supra, 27 Cal.App.5th
    at pp. 612-613.) The rating process begins by determining a standard rating for the
    injured worker’s impairment. Generally, a psychiatric impairment is evaluated by a
    physician using the GAF scale, and the resultant GAF score is converted to a WPI rating
    using the conversion table in the 2005 Schedule. The WPI rating is expressed as a
    percentage, which is then adjusted for the other factors listed in section 4660, subdivision
    (a)—diminished future earning capacity, occupation, and age at the time of injury—
    according to other tables in the schedule to obtain a final PD rating. (Fitzpatrick, at
    p. 613, citing 2005 Schedule, pp. 1-2, 1-12.) The schedule is intended to “ ‘ “promote
    consistency, uniformity, and objectivity” ’ ” in the rating process and constitutes
    “ ‘ “prima facie evidence of the percentage of permanent disability to be attributed to
    each injury covered by the schedule . . . .” ’ ” (Fitzpatrick, at p. 612, citing § 4660,
    subds. (c), (d), & Ogilvie, supra, 197 Cal.App.4th at p. 1271.)
    Section 4662, subdivision (a), identifies four instances of “permanent disabilities
    [that] shall be conclusively presumed to be total in character,” thus rating 100 percent
    51
    PD. None of those instances apply here.19 Section 4662, subdivision (b) (hereafter
    4662(b)), provides that “[i]n all other cases, permanent total disability shall be
    determined in accordance with the fact.” (Italics added.)
    One practice guide has stated that the language of section 4662(b) created
    uncertainty regarding its relationship to section 4660, which “ ‘prescribes the method for
    determining the percentages of permanent disability’ ” based on the applicable schedule.
    (Workers’ Comp. Practice, supra, § 5.7 (rev. 3/19), quoting Chang, supra, 153
    Cal.App.4th at p. 753.) A question arose before the WCAB whether section 4662(b)
    created an alternative path to establishing 100 percent PD separate and apart from the
    scheduled rating under section 4660 or attempting to rebut the scheduled rating under the
    case law. (Fitzpatrick, supra, 27 Cal.App.5th at p. 622 [referring to this theory as an
    “independent path”]; id. at p. 610 [a “separate path”]; id. at p. 621, fn. 13 [the WCJ and
    WCAB in Fitzpatrick used the phrase “different paths”]; see also Workers’ Comp.
    Practice, at § 5.7.) Some WCAB panel decisions endorsed the alternative path approach.
    (See, e.g., Anaya v. Bay Area Carbide (2016) 81 Cal.Comp.Cases 1061, 1063 (Anaya)
    [total PD may be shown by presenting evidence of 100 percent PD “in accordance with
    the fact” under section 4662(b) or by rebutting a section 4660 scheduled rating].) In
    2012, a WCAB panel held in Coca-Cola Enterprises, Inc. v. Workers’ Comp. Appeals
    Bd. (2012) 77 Cal.Comp.Cases 445, 447-448 (Jaramillo) that section 4662 applied to
    total PD (100 percent) and that section 4660 applied to partial PD (0 percent to 99.75
    percent).
    19
    Section 4662, subdivision (a) provides: “Any of the following permanent
    disabilities shall be conclusively presumed to be total in character: [¶] (1) Loss of both
    eyes or the sight thereof. [¶] (2) Loss of both hands or the use thereof. [¶] (3) An injury
    resulting in a practically total paralysis. [¶] (4) An injury to the brain resulting in
    permanent mental incapacity.”
    52
    In September 2018—after the WCJ issued his second amended decision and his
    report and recommendation on reconsideration in this case, but before the WCAB filed its
    decision—the Court of Appeal in Fitzpatrick declined to endorse the alternative path
    approach, rejected the WCAB’s interpretation of sections 4660 and 4662(b), and
    disapproved of Jaramillo. (Fitzpatrick, supra, 27 Cal.App.5th at pp. 620-621 & fn. 13.)
    The facts in Fitzpatrick are very similar to the facts here. The injured worker in
    Fitzpatrick claimed injuries to his heart and psyche. The psychiatrist reported that the
    injured worker’s GAF score was 45, which translated to a 40 percent WPI and a
    scheduled rating of 71 percent PD after adjustment for diminished earning capacity,
    occupation, and age. (Id. at p. 614.) The psychiatrist opined that Fitzpatrick “ ‘was . . .
    “on strict psychiatric grounds totally and permanently disabled,” ’ ” stated that he was
    “ ‘ “dubious” ’ ” that he “ ‘ “will return to work in any capacity,” ’ ” and said that “ ‘ “if
    his cardiac condition does not improve, he will not return to work.” ’ ” (Id. at p. 615.)
    The WCJ in Fitzpatrick relied on the construction of section 4662(b) in Jaramillo, found
    100 percent PD based on the psychiatrist’s report alone, and impliedly held that it was not
    necessary for the employee to rebut the scheduled rating under section 4660.
    (Fitzpatrick, at pp. 615-616.) The WCAB panel adopted the WCJ’s decision and denied
    reconsideration. (Id. at p. 615.)
    The appellate court “easily harmonize[d]” sections 4660 and 4662(b) and rejected
    the alternative path approach. (Fitzpatrick, supra, 27 Cal.App.5th at p. 618.) It held that
    in “nonconclusively presumed permanent total disability cases (i.e., those cases not
    enumerated in § 4662, subd. (a)), permanent total disability may be found ‘in accordance
    with the fact.’ This section does not, however, address how such a determination shall be
    made; read plainly, it merely provides that a determination of permanent total disability
    shall be made on the facts of the case.” (Fitzpatrick, at p. 618.) The court stated:
    “[s]ection 4660 addresses how the determination on the facts shall be made in each case
    53
    for injuries occurring before January 1, 2013. Indeed, section 4660 expressly applies to
    the determination of ‘the percentages of permanent disability’ and permanent total
    disability is defined by statute as a percentage of permanent disability, i.e., 100 percent.
    (§§ 4660, subds. (a), (d), 4452.5, subd. (a).) This definition of permanent total disability
    applies to the division in which section 4660 appears and was added in 1973 (predating
    the 2004 amendment to § 4660). (§ 4452.5; Stats. 1973, ch. 1023, § 1, p. 2028.) We
    presume the Legislature, when amending section 4660, was aware of existing related
    laws and intended to maintain a consistent body of statutes on the same subject matter.”
    (Fitzpatrick, at pp. 618-619.) The court noted that the 2005 Schedule also identifies
    permanent total disability as a percentage of disability. In its introduction, the 2005
    Schedule states that “ ‘A permanent disability rating can range from 0% to 100%. Zero
    percent signifies no reduction of earning capacity, while 100% represents permanent total
    disability. A rating between 0% and 100% represents permanent partial disability.’
    (2005 Schedule, p. 1-2.) A ‘final permanent disability rating’ is obtained by going
    through the steps outlined in the 2005 Schedule. (2005 Schedule, pp. 1-2 to 1-16.)”
    (Fitzpatrick, at p. 619.) The schedule is intended to “ ‘ “promote consistency, uniformity,
    and objectivity” ’ ” in the rating process and constitutes “ ‘ “prima facie evidence of the
    percentage of permanent disability to be attributed to each injury covered by the
    schedule . . . .” ’ ” (Id. at p. 612, citing § 4660, subds. (c), (d), & Ogilvie, supra, 197
    Cal.App.4th at p. 1271.)
    The Fitzpatrick court also observed that it is possible to obtain a 100 percent PD
    rating using the 2005 Schedule and that the scheduled rating under section 4660 is
    rebuttable. (Fitzpatrick, supra, 27 Cal.App.5th at pp. 619-620.) The court reasoned that
    the WCAB’s interpretation and approach would “ ‘return us to the ad hoc decisionmaking
    that prevailed prior to 2004’ ” and would allow a WCJ “to make a subjective
    determination that may lead to inconsistent and nonuniform permanent disability ratings
    54
    with respect to the most expensive claims under our workers’ compensation framework.
    Such a result cannot be squared with the Legislature’s intent.” (Id. at p. 622.) Thus, the
    court disapproved of the WCAB’s interpretation of sections 4660 and 4662, which
    permitted a finding of 100 percent PD under section 4662(b) without considering the
    scheduled rating under section 4660 or whether the evidence rebutted the scheduled
    rating. The court therefore annulled the decision and remanded to the WCAB for further
    proceedings. (Fitzpatrick, at pp. 610, 615-616, 624.)
    The instructions in section 1 of the 2005 Schedule describe “Rating Procedures,”
    including the use of the Guides, calculation of a rating, and “Additional Rating
    Procedures,” which contains a subsection entitled “Rating Psychiatric Impairment.”
    (2005 Schedule, p. 1-1.) The subsection on rating psychiatric impairment provides:
    “Psychiatric impairment shall be evaluated by the physician using the Global Assessment
    of Function[20] (GAF) scale shown below. The resultant GAF score shall then be
    converted to a whole person impairment rating using the GAF conversion table below.”
    (2005 Schedule, p. 1-12.) The 2005 Schedule contains instructions to the physician for
    determining a GAF score, followed by the GAF Scale, and the 2005 Schedule instructs
    the physician to “[c]onsider psychological, social, and occupational functioning on a
    hypothetical continuum of mental health-illness. Do not include impairment in
    functioning due to physical (or environmental) limitations.” (Id., p. 1-13.)
    The GAF Scale is divided into 11 sections; each section is assigned numerical
    codes in a 10-point range, with a general description of the psychiatric impairments in
    that range and examples of how the impairment affects function. (2005 Schedule,
    pp. 1-14 to 1-15.) The higher the GAF score, the less severe the psychiatric impairment.
    (Ibid.) Once the physician selects the appropriate 10-point range, the 2005 Schedule
    20
    The 2005 Schedule refers to this as both the “Global Assessment of Function”
    (2005 Schedule, p. 1-12, italics added) scale and the “Global Assessment of Functioning”
    scale (id., p. 1-13, italics added).
    55
    instructs the physician to “consider whether the individual is functioning at the higher or
    lower end of the 10 point range.” (Id. at p. 1-13.) Dr. Sidle assigned a GAF score of 45
    to Worker’s disability. That means she was functioning in the middle of the “41-50”
    range on the GAF Scale, which the 2005 Schedule defines as: “Serious symptoms (e.g.,
    suicidal ideation, severe obsessional rituals, frequent shoplifting) OR any serious
    impairment in social, occupational, or school functioning (e.g., no friends, unable to keep
    a job).” (Id., p. 1-14.) As noted, the schedule instructs the person preparing the rating to
    convert the GAF score to a standard WPI rating using the conversion table at page 1-16
    of the 2005 Schedule.
    Dr. Sidle reported that he understood a GAF score of 45 to mean that Worker
    “cannot hold a job” and is totally disabled. As noted, Arrowood asserts, a GAF score of
    45 converts to 40 percent WPI and adjusts to 70 percent PD under the 2005 Schedule in
    Worker’s case. In our initial review of Arrowood’s petition, we noted that there was no
    rating formula in the exhibits that confirmed the 70 percent figure. Our independent
    review of the 2005 Schedule suggested that the highest possible scheduled rating for a
    GAF score of 45 in Worker’s case was 68 or 70 percent depending on the date of injury,21
    not 100 percent.
    Arrowood argues that the WCAB’s affirmation of the WCJ’s 100 percent PD
    award, without considering the scheduled rating, was improper as the WCJ essentially
    relied on section 4662(b) and Dr. Sidle’s conclusory opinion that Worker was 100
    percent permanently disabled in direct contradiction of the holding in Fitzpatrick. When
    the WCJ issued his award in September 2017, the WCAB was still analyzing
    21
    We noted that a psychiatric disability takes the highest possible future earning
    capacity rank (an 8), which increases the standard rating from 40 percent to 56 percent.
    (2005 Schedule, pp. 2-3, 2-6.) Assuming the highest possible occupational variant (a J),
    the PD rating adjusts to 68 percent. (Id., pp. 4-1, 4-4, 4-5, 5-3.) Applying her age on the
    date of the 2001 injury, the rating remains at 68 percent; based on her age on the date of
    the 2008 injury, the PD rating adjusts to 70 percent. (Id., p. 6-4.)
    56
    nonpresumptive 100 percent PD cases under section 4662(b) and Jaramillo. The WCJ
    did not cite section 4662(b) or Jaramillo in his opinion on decision or his report on
    reconsideration. But according to the WCAB’s pretrial conference statement and
    Worker’s answer to Arrowood’s petition for reconsideration, Worker relied on
    section 4662(b) and Anaya, supra, 81 Cal.Comp.Cases 1061, a WCAB panel decision
    that applied the alternative path theory from Jaramillo to find 100 percent PD. Without
    citation to authority, Worker also argued that “[m]ultiple cases have held that a GAF of
    45 [means the injured worker] ‘cannot hold a job’ ” and that a finding of 100 percent PD
    is “mandated” when a QME psychiatrist finds the employee cannot work. It appears the
    WCJ agreed with Worker.
    Given this record, we asked for supplemental briefing on the following questions:
    “1. What is the scheduled rating under the 2005 schedule for rating permanent disability
    in [Worker’s] case based on her GAF score of 45? Please provide the rating formula. [¶]
    2. What was the statutory basis for the award of 100% permanent disability in this case?
    Did Dr. Sidle or the WCAB rely on an incorrect legal theory in finding 100% permanent
    disability? Was the permanent disability award here authorized under [Fitzpatrick]? [¶]
    3. Was there substantial evidence that rebutted the scheduled rating for [Worker’s]
    psychiatric disability under the standards described in [Fitzpatrick]? Please describe that
    evidence in detail and explain why or why not, with citations to legal authority and the
    record . . . .” We have reviewed the supplemental briefs, as well as amicus curiae briefs
    filed in support of both sides.22
    22
    Amici curiae for Petitioners are the California Workers’ Compensation Institute
    and the California Chamber of Commerce. The California Applicants’ Attorneys
    Association filed an amicus curiae brief in support of Worker and the WCAB.
    57
    In response to our first question, Petitioners contend that the scheduled rating
    based on a GAF score of 45, which converts to 40 percent WPI, was either 68 or 70
    percent pursuant to the following rating formulas:
    For the 2001 and 2005 injuries: 14.01.00 – 40 – [8] 56 – 110J – 68 – 68%
    For the 2008 injury:              14.01.00 – 40 – [8] 56 – 110J – 68 – 70%23
    Rather than provide a rating formula (i.e., rate the PD according to the factors
    described in section 4660 as per the instructions in the 2005 Schedule), Worker responds
    that “the scheduled rating is 100%. . . . The rating formula is simply – 100%,” that a
    “100% rating is not modified for FEC, age or occupation,” and that “[t]here is no ‘rating
    formula’ for 100%.” Worker relies on the description of permanent total disability in the
    introduction to the schedule, which states: “Permanent total disability represents a level
    of disability at which an employee has sustained a total loss of earning capacity.” (2005
    Schedule, pp. 1-2 to 1-3.) She contends that a GAF of 45 means she has no earning
    23
    These rating formulas begin with the number “14.01.00,” which is the
    “impairment number”—basically a code number—for “Psychiatric-Mental and
    Behavioral” impairments. (2005 Schedule, pp. 2-1, 2-3.) The second number (40), refers
    to the WPI percentage assigned to the impairment. As noted, according to the conversion
    table in the schedule, a GAF score of 45 converts to 40 percent WPI. (Id., p. 1-16.) The
    “[8]” refers to the “FEC rank,” an adjustment for diminished future earning capacity. A
    psychiatric disability takes the highest possible FEC rank, an 8. (Id., pp. 1-5 to 1-7, 2-3.)
    The number “56” refers to the adjustment of the standard rating based on her FEC rank;
    according to the Future Earning Capacity (FEC) Adjustment Table, this increased her
    standard rating from 40 percent to 56 percent. (Id., p. 2-6.) The “110J” refers to the
    occupational group and occupational variant. At trial, the parties stipulated that Worker’s
    job fit occupational group number 110, which covers numerous occupations in the
    “Professional, Technical, Clerical” occupation group and takes the highest possible
    occupational variant (a J) for psychiatric disabilities. (Id., pp. 3-15, 3-27, 3-29, 4-1, 4-4.)
    According to the Occupational Adjustment Table, a 56 percent PD rating adjusts to 68
    percent for occupational variant J. (Id., p. 5-3.) The last number in the rating formula
    represents the adjustment for age at the time of injury. Applying Worker’s age on the
    dates of the 2001 and 2005 injuries (38 & 41), her 68 percent PD rating remains at 68
    percent; based on her age on the date of the 2008 injury (44), her scheduled PD rating
    adjusts to 70 percent. (Id., p. 6-4.)
    58
    capacity since the 2005 Schedule describes GAF scores in the 41-50 range as “ ‘Serious
    symptoms . . . any serious impairment in social, occupational, or school functioning (e.g.,
    no friends, unable to keep a job)’ ” and a person who cannot keep a job has no earning
    capacity.
    We are not persuaded that the general language describing permanent total
    disability in the introduction to the schedule is controlling or takes precedence over the
    more specific, detailed instructions for rating psychiatric impairment on pages 1-12
    through 1-16 of the 2005 Schedule or the mandate of section 4660, which requires
    consideration of the four factors listed in section 4660 to determine the percentages of
    PD. Worker would have us ignore the requirement that the GAF score be converted to a
    WPI percentage (2005 Schedule, pp. 1-12, 1-15 to 1-16), as well as the adjustments
    mandated by section 4660, subdivision (a) and the 2005 Schedule “to reflect diminished
    future earning capacity, the occupation and the age at the time of injury” (2005 Schedule,
    p. 1-4).
    As the Fitzpatrick court noted, it is possible to obtain a scheduled rating of 100
    percent PD. (Fitzpatrick, supra, 27 Cal.App.5th at p. 619.)24 As for psychiatric PD, a
    GAF score of 29 or less converts to a WPI of 71 percent or more, which in Worker’s case
    would result in 100 percent PD when adjusted for diminished future earning capacity,
    occupation, and age. (2005 Schedule, pp. 1-16, 2-7, 5-3, 6-5.) Conversely, a GAF score
    of 30 or more (Dr. Sidle assigned a GAF score of 45) results in a rating of less than 100
    percent. For these reasons, we reject Worker’s assertion that the scheduled rating based
    24
    The Fitzpatrick court noted that “ ‘[T]he final overall permanent disability
    rating percentage for a single impairment’ is shown ‘on the age adjustment table,’ which
    contains a 100 percent disability rating. (2005 Schedule, pp. 1-9, 6-5.) For combined
    impairments or disabilities, the Chart also contains over 50 combined ratings of 100
    percent. (2005 Schedule, pp. 8-1, 8-3 to 8-4.)” (Fitzpatrick, supra, 27 Cal.App.5th at
    p. 619.)
    59
    on a GAF score of 45 is 100 percent and conclude that the ratings submitted by
    Petitioners accurately reflect the scheduled PD rating in this case.
    Worker does not respond directly to our question regarding the statutory basis for
    her PD award. She does not acknowledge her citation of section 4662(b) and the Anaya
    case in her briefs below. Instead, she argues that Fitzpatrick was wrongly decided and
    that it judicially repealed section 4662(b). We agree with the statutory analysis in
    Fitzpatrick, which rejected the alternative path interpretation of section 4662(b) in cases
    like Jaramillo and Anaya.
    We also reject Worker’s assertion that Fitzpatrick effectively repealed
    section 4662(b). Consistent with the plain language of section 4662(b) that
    nonpresumptive cases of total PD are to be decided “in accordance with the fact,”
    Fitzpatrick holds that the PD is determined first in accordance with the scheduled rating
    and the factors enumerated in section 4660 and that the language of section 4660 makes
    this step mandatory. (Fitzpatrick, supra, 27 Cal.App.5th at p. 622.) Depending on the
    facts of the case, it is possible to obtain a scheduled rating of 100 percent PD under the
    2005 Schedule. The Fitzpatrick court also acknowledged that the scheduled rating is
    rebuttable pursuant to rules developed in the case law, which gives the injured worker
    “the opportunity to present evidence supporting a 100 percent disability rating when the
    scheduled rating is less.” (Id. at p. 620.) Thus, the injured worker may obtain a 100
    percent PD award by demonstrating that based on the facts, his or her disability is greater
    than that reflected in the scheduled rating. Since Fitzpatrick acknowledged these two
    paths for showing total PD under section 4662(b), it did not effectively repeal that
    section.25
    25
    In support of her contention that Fitzpatrick was wrongly decided, Worker
    asked us to review the WCJ’s report and recommendation on reconsideration (not the
    WCAB panel decision) in Bagobri v. A.C. Transit (2019) 85 Cal.Comp.Cases 61. At oral
    (continued)
    60
    “Factual determinations of the [WCAB] must be upheld if there is substantial
    evidence to support them, and the relevant and considered opinion of one physician, . . .
    normally constitutes substantial evidence.” (Patterson v. Workers’ Comp. Appeals Bd.
    (1975) 
    53 Cal.App.3d 916
    , 921, citing Place v. Workmen’s Comp. App. Bd. (1970) 
    3 Cal.3d 372
    , 378.) But “a medical opinion is not substantial evidence if it is based on
    facts no longer germane, on inadequate medical histories or examinations, on incorrect
    legal theories, or on surmise, speculation, conjecture, or guess.” (E.L. Yeager
    Construction v. Workers’ Comp. App. Bd. (2006) 
    145 Cal.App.4th 922
    , 928, italics
    added, citing Hegglin v. Workmen’s Comp.App.Bd. (1971) 
    4 Cal.3d 162
    , 169.) “A
    factual finding, order, decision or award is not based on substantial evidence if
    unreasonable, illogical, arbitrary, improbable or inequitable considering the entire record
    and statutory scheme.” (Genlyte, supra, 158 Cal.App.4th at p. 723, fn. 18.) A medical
    opinion that is beyond the physician’s expertise is not substantial evidence. (Ibid.)
    Our review of the record supports the conclusion that Worker relied on the
    alternative path theory to support her claim of total PD. As noted, the joint pretrial
    conference statement indicated that she claimed total PD under section 4662(b), and she
    cited both section 4662(b) and Anaya in her answer to the petition for reconsideration.
    Dr. Sidle reported that her GAF score was 45, which he understood to mean “that she
    cannot hold a job” and would be “considered totally disabled.” But a GAF score results
    argument, Worker’s counsel stated that the WCJ’s report in Bagobri is the only decision
    that criticizes Fitzpatrick. The WCJ’s analysis in Bagobri is not binding on any other
    WCJ, the WCAB, or this court. (Gee v. Workers’ Comp. Appeals Bd. (2002) 
    96 Cal.App.4th 1418
    , 1424, fn. 6 [unlike the WCAB’s en banc decisions, WCAB panel
    decisions are not binding on other WCAB panels or WCJ’s].) We have reviewed the
    decision in Bagobri and do not find the WCJ’s criticism of Fitzpatrick persuasive. In
    addition, there was more than sufficient medical, psychiatric, and vocational evidence in
    Bagobri that supported the WCJ’s award of 100 percent PD and the conclusion that the
    injured worker in that case had rebutted his scheduled rating in accordance with
    Fitzpatrick.
    61
    in a PD rating of 68 or 70 percent under the 2005 Schedule, not total disability.
    Dr. Sidle’s opinion is also consistent with the argument Worker makes in this proceeding
    based on the definition of permanent total disability in the introduction to the 2005
    Schedule, a legal argument that we have rejected. For these reasons, we conclude that
    Dr. Sidle relied on an incorrect legal theory (the alternative path theory) when he found
    that Worker was totally disabled. His opinion therefore does not constitute substantial
    evidence that supports the WCAB’s award.
    The WCJ did not cite section 4662(b) or Jaramillo or Anaya in his opinion on
    decision or in his report on reconsideration. But the WCJ clearly agreed with Worker’s
    view of the case. Thus, it appears the WCJ relied on the alternative path theory that was
    later rejected in Fitzpatrick to award 100 percent PD. Fitzpatrick was final in February
    2019. By the time the WCAB issued its decision here in June 2019, the Fitzpatrick court
    had disapproved of Jaramillo. . But nothing in the WCAB’s decision indicates that it
    considered the scheduled rating or Fitzpatrick or whether Worker had presented
    substantial evidence to rebut the scheduled rating when it reviewed this matter.
    Worker’s reliance on Qualcomm, Inc. v. Workers’ Comp. Appeals Bd. (2019) 84
    Cal.Comp.Cases 531 (Qualcomm) is misplaced. In that case, the WCAB adopted the
    reasoning of the WCJ, who found that the injured worker had rebutted the scheduled
    rating in accordance with LeBoeuf, supra, 
    34 Cal.3d 234
    . (Qualcomm, at pp. 533-534.)
    The WCJ in Qualcomm did not rely on section 4662(b) as an alternative path to award
    total PD.26
    26
    Worker relies in part on the unpublished writ denial opinion of the appellate
    court in Qualcomm. Court of Appeal opinions that are not published in the Official
    Reports, even though available in print in the California Compensation Cases, may not be
    cited or relied upon in any court. (Cal. Rules of Court, rule 8.1115.) On the other hand,
    WCAB panel decisions and denials of petitions for writ of review reported in the
    California Compensation Cases, along with WCAB denials of petitions for

    62
    In our request for supplemental briefing we also asked the parties whether there
    was substantial evidence that rebutted the scheduled ratings in this case. Petitioners
    contends that Worker failed to introduce substantial evidence that rebutted the scheduled
    ratings. Petitioners argue that rebutting the scheduled rating required vocational
    evidence, that Dr. Sidle was not a vocational expert, that it is improper for a doctor to
    opine that the employee is unable to compete on the open labor market, and that there
    was no vocational evidence here. They contend that while Dr. Sidle opined that Worker
    could not work eight hours a day, five days a week, he failed to consider a wide range of
    available jobs, part-time work, or at-home work. Moreover, they contend that under
    LeBoeuf, Worker was required to show that she was not amenable to vocational
    rehabilitation. Worker responds that she was not required to rebut the scheduled rating
    because the scheduled rating was 100 percent.
    Section 4660, subdivision (c) provides that “without formal introduction in
    evidence,” the 2005 Schedule “shall be prima facie evidence of the percentage of
    permanent disability to be attributed to each injury covered by the schedule.” As this
    court observed in Guzman, “ ‘A statute providing that a fact or group of facts is prima
    facie evidence of another fact establishes a rebuttable presumption.’ (Evid. Code, § 602.)
    Accordingly, as ‘prima facie evidence’ the Schedule is not ‘absolute, binding and final.
    [Citations.] It is therefore not to be considered all of the evidence on the degree or
    percentage of disability. Being prima facie it establishes only presumptive evidence
    [which] may be controverted and overcome.’ ” (Guzman, supra, 187 Cal.App.4th at
    p. 826; brackets in Guzman.) Thus, the schedule “may be rebutted based on the specific
    reconsideration reported in other sources, are properly citable authority, but only to the
    extent that they point out the contemporaneous interpretation and application of the
    workers compensation laws by the WCAB. (Smith v. Workers’ Comp. Appeals Bd.
    (2000) 
    79 Cal.App.4th 530
    , 537, fn. 2.) “Although we encourage citation of these cases,
    we emphasize that they are of limited precedential value and unquestionably have no
    stare decisis effect in an appellate court.” (Ibid.)
    63
    circumstances of a case.” (Fitzpatrick, supra, 27 Cal.App.5th at p. 614, citing Ogilvie,
    supra, 197 Cal.App.4th at pp. 1266-1276.)
    Worker argues that the award here was due to a failure of proof by Petitioners.
    We disagree. The rebuttable presumption established by section 4660, subdivision (c) is
    a presumption affecting the burden of proof, and the burden of rebutting a scheduled
    rating rests with the party disputing the rating. (Almaraz v. Environmental Recovery
    Services (2009) 74 Cal.Comp.Cases 1084, 1097-1098 [WCAB en banc], citing Evid.
    Code, §§ 601, 605.) Since Worker disputed the scheduled ratings of 68 and 70 percent,
    she had the burden of presenting substantial evidence that rebutted those ratings.
    After the Legislature amended section 4660 in 2004, several cases discussed
    methods for rebutting a scheduled rating. (See, e.g., Guzman, supra, 187 Cal.App.4th at
    pp. 826-829 [rebuttal of impairment standard/WPI rating]; Ogilvie, supra, 197
    Cal.App.4th at pp. 1273-1277 [rebutting FEC component of rating]; Contra Costa County
    v. Workers’ Comp. Appeals Bd. (2015) 
    240 Cal.App.4th 746
    , 751 (Dahl) [rebuttal based
    on alternative calculation of FEC component of rating].) There are three ways to rebut
    the FEC component of a scheduled rating. First, the schedule may be rebutted when a
    party can show a factual error in the application of a formula or the preparation of the
    schedule. Second, when amending section 4660, the Legislature left intact cases,
    including LeBoeuf, supra, 
    34 Cal.3d 234
    , which hold that a scheduled rating has been
    effectively rebutted when the injury impairs the employee’s rehabilitation, and for that
    reason, the employee’s diminished future earning capacity is greater than reflected in the
    scheduled rating. Third, the scheduled rating may be rebutted when the employee can
    demonstrate that the nature or severity of the injury was not captured within the
    sampling of disabled workers that was used to compute the adjustment factor.
    (Fitzpatrick, supra, 27 Cal.App.5th at p. 620, citing Dahl, supra, at p. 751; see also
    Ogilvie, at pp. 1273-1277.) The method that arguably applies here is the second method.
    64
    The employee in LeBoeuf was working as a bus driver when he was attacked and
    beaten by four youths. He sustained multiple contusions and abrasions, and developed an
    anxiety neurosis. A WCJ found that his psychiatric injury caused 60 percent PD and
    awarded benefits based on that rating. (LeBoeuf, supra, 34 Cal.3d at pp. 237-238.) The
    Rehabilitation Bureau of the WCAB later determined, based on evidence from vocational
    rehabilitation experts, that LeBoeuf would not be able to return to suitable gainful
    employment through vocational rehabilitation services. (Id. at pp. 239-240.) The injured
    worker petitioned to reopen his case, arguing that he was entitled to an award of 100
    percent PD since it was not feasible for him to participate in vocational rehabilitation.
    The WCAB denied the petition to reopen. (Id. at p. 240.) Our Supreme Court observed
    that the provision of rehabilitation benefits will have a significant impact on an injured
    worker’s ability to compete and held that “the fact that an injured employee is precluded
    from the option of receiving rehabilitation benefits should also be taken into account” in
    assessing the injured worker’s PD rating. (Id. at p. 243.) The court concluded that the
    finding that LeBoeuf was not qualified for vocational rehabilitation benefits was good
    cause to reopen. (Id. at p. 246 & fn. 12.)
    “The first step in any LeBoeuf analysis is to determine whether a work-related
    injury precludes the claimant from taking advantage of vocational rehabilitation and
    participating in the labor force. This necessarily requires an individualized approach.”
    (Dahl, supra, 240 Cal.App.4th at p. 758.) A scheduled rating is not rebutted by evidence
    that the injured worker cannot be returned to his or her pre-injury earning capacity. (Id.
    at p. 759.) In Dahl, both parties presented evidence from vocational experts on the
    injured worker’s ability to take advantage of retraining opportunities or to find a new job.
    (Id. at pp. 758-759.)
    Dr. Sidle reported that in 2016, Worker was even more anxious and depressed
    than before, and since her symptoms were worse, he reduced her GAF score from 51 to
    65
    45, which he understood to mean “that she cannot hold a job” and is totally disabled. He
    opined “that she is clearly not able to work at this time.” He reported that she had
    “various deficits in self-esteem and self-confidence; also loss of interest in usual
    activities.” The factors that impacted her ability to work included “her anxiety and
    depression; her difficulty with sleep; her decreased energy; her decreased concentration,”
    “the fact that she physically cannot do many of the things that she normally did,” “fatigue
    from not sleeping as fully as possible and from her chronic stress.” He opined that it was
    not possible for her “to meet the demands of an employer on a steady basis eight hours a
    day, five days a week.” In deposition, he agreed that she was 100 percent “disabled from
    working in the open labor market.”
    The WCAB has held that the role of the medical evaluator in workers’
    compensation cases is to assess work restrictions and resulting permanent impairment.
    (Blackledge v. Bank of America (2010) 75 Cal.Comp.Cases 613, 619-621 [WCAB en
    banc].) In LeBoeuf, the evidence regarding the injured worker’s employability included
    conflicting opinions from two psychiatrists and conflicting opinions from two vocational
    experts. (LeBoeuf, supra, 34 Cal.3d at pp. 237, 238.) In Merino v. Workers’ Comp.
    Appeals Bd. (2001) 66 Cal.Comp.Cases 405, 406 (writ denied), the WCAB held that
    while it is proper for a doctor to give an opinion on whether an injured worker can
    perform his or her usual and customary duties, opinions about “ ‘competing in the open
    labor market’ ” are beyond the doctor’s expertise, and must be left to a vocational
    rehabilitation specialist. In Morris v. Workers’ Comp. Appeals Bd. (2014) 79
    Cal.Comp.Cases 1348, 1350 (writ denied), the WCJ found that the record did not support
    a finding of 100 percent PD because the injured worker failed to produce sufficient
    evidence to rebut the scheduled rating. The WCJ stated that to effectively rebut a
    scheduled rating pursuant to LeBoeuf and Ogilvie, “an injured worker must present
    vocational expert evidence, in addition to medical evidence, proving that his or her
    66
    diminished future earning capacity is greater than that reflected in the schedule” and
    found that “[i]t is improper for a doctor to deem an applicant 100% permanently disabled
    based on the doctor’s opinion that the applicant is unable to compete on the open labor
    market.” (Ibid.) A majority of the WCAB panel denied reconsideration and adopted the
    WCJ’s reasoning as its decision. One commissioner “disagreed with the WCJ’s
    suggestion that a physician’s determination that an injured worker is not able to compete
    in the open labor market is inadequate rebuttal evidence.” (Id. at p. 1353.)
    Based on this authority, we agree that Worker did not meet her burden of rebutting
    the FEC component of the scheduled rating in accordance with LeBoeuf. Dr. Sidle did
    not opine on Worker’s ability to participate in vocational rehabilitation, take advantage of
    training opportunities, or find work. While Dr. Sidle was able to opine on these matters
    from a medical or psychiatric standpoint, he was not a vocational expert, he was not
    qualified to opine on these points from a vocational perspective or opine that she was 100
    percent “disabled from working in the open labor market.” As Petitioners note, while
    Dr. Sidle stated that it was not possible for her “to meet the demands of an employer on a
    steady basis eight hours a day, five days a week,” Dr. Sidle did not consider part-time
    work, work at home, other alternative work settings, retraining options, or her ability to
    participate in vocational rehabilitation.
    Another way to rebut the scheduled rating is to challenge the impairment standard
    used in the scheduled rating (40 percent WPI in this case). (Guzman, supra, 187
    Cal.App.4th at pp. 826-829.) Although the WCAB panel decision in Golden Gate
    Bridge, Highway & Transportation Dist. v. Workers’ Comp. Appeals Bd. (2018) 83
    Cal.Comp.Cases 1704 (writ denied) involves rebuttal evidence in cases rated under the
    Guides, not the GAF scale, it provides some guidance for evaluating the rebuttal of an
    impairment standard under the 2005 Schedule. The WCAB explained that to properly
    rebut a PD rating, “a physician is expected to: (1) provide a strict rating per the AMA
    67
    Guides; (2) explain why the strict rating does not accurately reflect the employee’s
    disability; (3) provide an alternative rating within the four corners of the AMA Guides;
    and (4) explain why the alternative rating most accurately reflects the employee’s level of
    disability.” (Id. at p. 1706; see also Guzman, at pp. 828-829.) Dr. Sidle provided a strict
    rating under the schedule’s GAF scale by assigning a score of 45, which converts to 40
    percent WPI. But he erroneously assumed that a GAF of 45 meant she was 100 percent
    disabled. Dr. Sidle described various factors that affect Worker’s ability to work, but did
    not explain why the 40 percent WPI score did not accurately reflect her disability,
    provide an alternative rating within the GAF scale, or explain why that rating more
    accurately reflected the level of her disability. He did not cite any extrinsic resources
    (i.e., standard texts or recent research data) that supported deviating from the WPI
    assigned by the schedule. (Guzman, supra, 187 Cal.App.4th at p. 829.) For these
    reasons, we conclude that Worker did not meet her burden of rebutting the scheduled
    rating.
    Since Dr. Sidle, the WCJ, and the WCAB all relied on an incorrect legal theory,
    the alternative path theory, to find 100 percent PD and Worker’s evidence did not rebut
    the scheduled rating of 68 or 70 percent, we conclude that the award of 100 percent PD is
    not supported by substantial evidence. We shall therefore annul the WCAB’s decision
    and return these cases to the WCAB for further proceedings consistent with the opinions
    stated herein.
    9. Apportionment should be considered on remand
    Arrowood argues that Dr. Sidle’s opinions are not substantial evidence because he
    failed: (1) to apportion between the three industrial injuries and opined instead that the
    three injuries were inextricably intertwined; (2) to apportion to nonindustrial factors
    (stressors in her history); and (3) to apportion to the pain disorder and depression that
    predated her 2013 PTSD diagnosis. Since we annul the WCAB’s decision and remand
    68
    for further proceedings, these issues are moot. We provide the following observations on
    the issue of apportionment for the parties’ and the WCAB’s guidance on remand.
    After the legislative reforms in 2004, “the new approach to apportionment is to
    look at the current disability and parcel out its causative sources—nonindustrial, prior
    industrial, current industrial—and decide the amount directly caused by the current
    industrial source.” (Brodie, supra, 40 Cal.4th at p. 1328.) This requires evaluating
    physicians, the WCJ, and the WCAB to “ ‘ “make an apportionment determination by
    finding what approximate percentage” ’ ” of the PD was a direct result of each industrial
    injury and what approximate percentage of the PD “ ‘ “was caused by other factors both
    before and subsequent to the industrial injury, including prior industrial injuries.” ’ ”
    (Acme Steel v. Workers’ Comp. Appeals Bd. (2013) 
    218 Cal.App.4th 1137
    , 1143.)
    In Benson, supra, 170 Cal.App.4th at page 1560, the Court of Appeal recognized
    that “there may be limited circumstances, . . . when the evaluating physician cannot
    parcel out, with reasonable medical probability, the approximate percentages to which
    each distinct industrial injury causally contributed to the employee’s overall permanent
    disability.” In such limited circumstances, the physicians’ apportionment determination
    “could properly be that the approximate percentages of disability caused by each of the
    successive injuries cannot reasonably be determined. As a result, the employee would be
    entitled to an undivided (i.e., joint and several) award for the combined permanent
    disability, because the respective defendants would have failed in their burdens of proof
    on the issue of apportionment.” (Id. at p. 1541, fn. 3.) The question is whether this case
    presents one of those “limited circumstances.”
    Workers’ compensation law also recognizes that the need for medical care may
    result from the combined effects of more than one injury. In such cases, a joint and
    several award of medical treatment in favor of the employee is permitted, subject to later
    apportionment between the responsible employers or carriers. (§ 3208.2; Zenith
    69
    Insurance Co. v. Workers’ Comp. Appeals Bd. (1981) 
    124 Cal.App.3d 176
    , 189.) The
    employer or its insurer has the burden of proof on apportionment because it is the
    employer who benefits from apportionment. (Benson, supra, 170 Cal.App.4th at p. 1541,
    fn. 3; Kopping v. Workers’ Comp. Appeals Bd. (2006) 
    142 Cal.App.4th 1099
    , 1115.)
    10. Arrowood’s contentions that the WCAB ordered total PD at the wrong
    weekly rate for the 2001 injury and that it erred in directing Arrowood to
    administer the award have been waived
    The WCAB awarded total PD starting on October 7, 2010, at $916.33 per week,
    subject to statutory cost of living adjustments (§ 4659, subd. (c)). Arrowood argues that
    the WCAB awarded total PD at the wrong weekly rate for the 2001 injury and that the
    correct rate was $490 per week. We conclude this issue is not cognizable in this writ
    proceeding, since Arrowood failed to raise it in either of its petitions for reconsideration
    to the WCAB. (§ 5904 [“all objections, irregularities, and illegalities” not raised in the
    petition for reconsideration are deemed to have been “finally waived”]; Bussa v.
    Workers’ Comp. Appeals Board (1968) 
    259 Cal.App.2d 261
     [points not raised in petition
    for reconsideration are deemed finally waived and cannot be considered on review by
    appellate court]; Guerra v. Workers’ Comp. Appeals Bd. (2016) 
    246 Cal.App.4th 1301
    ,
    1305, fn. 3.)
    Arrowood argues that since the WCAB ordered total PD at the 2008 rate, XL
    Specialty “should be the administering party,” since XL Specialty was the carrier for the
    2008 injury. The WCAB’s selection of a certain carrier to administer an award is a
    matter of discretion. The court may disturb the WCAB’s selection only where a clear
    abuse of discretion has been shown as when the rationale behind the WCAB’s selection is
    clearly erroneous. (General Ins. Co. of Am. v. Workers’ Comp. Appeals Bd. (1980) 
    104 Cal.App.3d 278
    , 286-287 [WCAB abused its discretion in selecting carrier who had only
    16 days coverage over carriers with years of coverage when choice was based on
    erroneous legal reasoning].) We conclude that this point cannot be considered on review
    70
    in this writ proceeding because Arrowood failed to raise it before the WCAB. (§ 5904.)
    Moreover, Arrowood has not cited any legal authority that supports this point, has not
    explained how the WCAB abused its discretion in selecting it to administer the award, or
    otherwise demonstrated that the choice was clearly erroneous.
    Accordingly, we conclude that the issues of the weekly rate for permanent total
    disability for the 2001 injury and the choice of defendant to administer the award are
    waived in the writ proceedings before us.
    V. CONCLUSIONS
    The following is a summary of our conclusions and holdings in these cases:
    (1) We reject XL Specialty’s contention that the correct date of injury for the
    cumulative trauma was in March 2002.
    (2) On the issue of industrial causation, we conclude that Worker met her burden
    of proving that her PTSD was a compensable consequence injury that resulted from the
    treatment for her industrial injuries and that her employment was one of the contributing
    causes without which the PTSD would not have occurred. We reject Petitioners’
    contention that the sexual conduct here was consensual, since as a matter of law a patient
    cannot consent to sexual contact with his or her physician (Bus. & Prof. Code, § 729,
    subd. (b)), as well as their contention that the PTSD is not compensable under the rules
    governing industrial injuries arising out of assaults by third parties.
    (3) We reject XL Specialty’s assertion that it is not liable for Worker’s psychiatric
    disability since it did not authorize or pay for any of the treatment with Dr. Massey or his
    clinic. Substantial evidence supports the conclusion that Dr. Massey treated Worker for
    injuries sustained during XL Specialty’s coverage period.
    (4) We reject XL Specialty’s challenges to the sufficiency of Dr. Feinberg’s AME
    reports to support the WCAB’s finding of orthopedic injuries during XL Specialty’s
    coverage period.
    71
    (5) We conclude that substantial evidence supported the WCAB’s finding that
    Worker’s PTSD was due in part to her 2001 injury since Dr. Massey treated Worker for
    all three injuries and Arrowood authorized and paid for the treatment with Dr. Massey.
    (6) We hold that there was substantial evidence of a new need for medical
    treatment, including psychiatric treatment, before November 2006 that supported the
    WCAB’s finding of new and further disability from the November 2001 injury.
    (7) We reject Arrowood’s contention that Dr. Sidle’s report was not substantial
    evidence because he evaluated Worker’s PD under the wrong rating schedule and hold
    that in the circumstances in this case, the 2005 Schedule applies to Worker’s psychiatric
    PD claims.
    (8) We conclude that the 100 percent PD award must be annulled because: (a) the
    psychiatric reports that the WCAB relied on do not constitute substantial evidence since
    Dr. Sidle relied on an incorrect legal theory, the alternative path theory, that was rejected
    in Fitzpatrick, supra, 
    27 Cal.App.5th 607
    ; and (b) Worker’s evidence was otherwise
    insufficient to rebut the scheduled rating for her psychiatric disability.
    (9) Since we are remanding this case for further proceedings on PD, we conclude
    that Arrowood’s assertions regarding apportionment are moot. We nonetheless provide
    some authority on the law of apportionment for guidance on remand.
    (10) We conclude that Arrowood’s contentions that the WCAB ordered total PD
    benefits at the wrong weekly rate for the 2001 injury and that the WCAB erred in
    ordering it to administer the joint and several PD award are not cognizable in these
    proceedings.27
    27
    Since we annul the award and remand the matter for further proceedings before
    the WCAB, we conclude that Arrowood’s request for a stay pending review is moot.
    72
    VI. DISPOSITION
    The WCAB’s decision after reconsideration is annulled and the matter is
    remanded to the WCAB for further proceedings consistent with our opinion. Each
    party shall bear its or her own costs in these proceedings. (Cal. Rules of Court,
    rule 8.493(a)(1)(B).)
