    1
    Under California law, hospitals must provide emergency room services without
    regard for a patient’s ability to pay or who will ultimately bear responsibility for the
    medical bill. (Prospect Medical Group, Inc. v. Northridge Emergency Medical Group
    (2009) 
    45 Cal.4th 497
    , 501-502 (Prospect).) Depending on who pays the bill for
    emergency room services, billing rates for the same treatment can vary substantially.
    (Howell v. Hamilton Meats & Provisions, Inc. (2011) 
    52 Cal.4th 541
    , 552, 560 (Howell).)
    After patients have received their care, hospitals often face the difficult and complex
    task of trying to secure payment for the emergency room services. The final cost and
    identity of the responsible payer of the emergency room services can remain unresolved
    for years.
    Sometimes a patient needs emergency room care due to negligent driving by a
    third party tortfeasor with automobile liability insurance coverage. In such an instance,
    the hospital with the emergency room must determine whether the medical bills are the
    responsibility of the patient, the patient’s health care service plan, the tortfeasor, the
    tortfeasor’s liability insurer, or some combination of these potential payers. (Prospect,
    supra, 45 Cal.4th at pp. 501-502; Parnell v. Adventist Health System/West (2005) 
    35 Cal.4th 595
    , 598 (Parnell); Health & Saf. Code, § 1371.4, subd. (b).) Further
    complicating a hospital’s endeavor to bill for emergency room services are varying
    limits on financial responsibility for the medical services. A patient’s financial
    responsibility may be limited to the copayment amounts specified by the health care
    service plan. (Parnell, at p. 611, fn. 15.) The patient’s health care service plan may be
    limited to paying a negotiated rate that is less than the hospital’s customary billing rate. 1
    1      We refer to the lower billing rates payable by health care service plans having
    contracts with hospitals as “negotiated rates.” Although negotiated rates are lower than
    the “customary rates” charged for emergency room services, they do not necessarily
    constitute “discount” rates. The California Supreme Court has explained that “if it were
    established a medical provider’s full bill generally represents the value of the services
    provided, and the discounted price negotiated with the insurer is an artificially low
    2
    (Id. at p. 609.) Many hospitals enter into contracts with health care service plans to
    ensure sufficient volume for their emergency rooms and in turn pass along the savings
    for “buying in bulk” the emergency room services provided. While many health care
    service plans contract for such negotiated rates, most automobile liability insurers do not.
    The health care service plan in this case, Kaiser Permanente (Kaiser), covered
    three patients who received care at an emergency room operated by Dameron Hospital
    Association (Dameron). The patients were injured due to the negligence of third party
    tortfeasors who had automobile liability insurance with California Automobile
    Association Inter-insurance Bureau (AAA)2 and Allstate Insurance Company (Allstate).
    Unlike Kaiser, neither AAA nor Allstate has contracts with Dameron. In the absence of
    an agreement for negotiated billing rates, Dameron sought to collect from AAA and
    Allstate its customary billing rates by asserting liens filed under the Hospital Lien Act
    (HLA). (Civ. Code, § 3045.1 et seq.) AAA and Allstate, however, ignored Dameron’s
    HLA liens when paying settlements to the three Kaiser patients.
    Upon learning of the settlements, Dameron sued AAA and Allstate to recover on
    its HLA liens. The trial court granted the automobile liability insurers’ motions for
    summary judgment on grounds the patients’ debts had already been fully satisfied by
    their health care service plans. Reasoning the HLA liens were extinguished for lack of
    any underlying debt, the trial court dismissed the case. The trial court further found
    dismissal was warranted because Dameron failed to timely file some of its HLA liens
    against AAA.
    fraction of that true value, one could make a parallel argument that relieving the
    defendant of paying the full bill would result in underdeterrence. The complexities of
    contemporary pricing and reimbursement patterns for medical providers, however, do not
    support such a generalization.” (Howell, supra, 52 Cal.4th at p. 560.)
    2     California Automobile Association Inter-insurance Bureau is now named AAA
    Northern California, Nevada and Utah Insurance Exchange.
    3
    The central question presented in Dameron’s appeal is this: Does a health care
    service plan’s payment of a previously negotiated rate for emergency room services
    insulate the tortfeasor’s automobile liability insurer from having to pay the customary
    rate for medical care rendered? AAA and Allstate contend they are not responsible for
    any amount after Kaiser paid in full the bill for the emergency room services provided by
    Dameron. Dameron responds that it contracted with Kaiser to preserve its rights to
    recover the customary billing rates from tortfeasors and their automobile liability
    insurers. Dameron asserts the tortfeasors and their liability insurers are responsible for
    the entire bill for medical services at the customary rate –- not just the difference between
    the reimbursement received from Kaiser and the customary billing rate.
    In Parnell, 
    supra,
     
    35 Cal.4th 595
    , the California Supreme Court unanimously held
    hospitals may not recover their customary rates for emergency room care when they have
    contractually agreed to accept negotiated rates as payment in full. (Id. at p. 609.) In so
    holding, the Supreme Court acknowledged that “California hospitals face mounting
    financial pressures, and that many, if not all, of these hospitals may ‘face a genuine
    financial crisis that threatens their ability to continue to serve their communities.’ ” (Id.
    at p. 611.) Parnell noted its holding might “result in a significant hardship for many of
    these hospitals.” (Ibid.) To alleviate such hardship, the Supreme Court stated hospitals
    could turn to the Legislature for changes to the HLA. (Id. at p. 611.)
    More importantly for purposes of this case, the Parnell court held that “the
    solution lies in the hands of the hospitals. By precluding the Community Hospital
    from asserting a lien under the HLA in this case, we ‘simply give[] effect to’ its contracts.
    (Lopez v. Morley [(2004)] 817 N.E.2d [592,] 599.) If hospitals wish to preserve their
    right to recover the difference between usual and customary charges and the negotiated
    rate through a lien under the HLA, they are free to contract for this right. Our decision
    today does not preclude hospitals from doing so. (See, e.g., Andrews [v. Samaritan
    Health System (Ct. App. 2001)] 36 P.3d [57,] 61.)” (Parnell, 
    supra,
     35 Cal.4th at p. 611.)
    4
    Although Dameron claims it should benefit from the California Supreme Court’s
    holding that it may avoid extinguishment of its HLA liens upon receiving payments from
    health insurers, the contract in this case preceded Parnell by 10 years. The
    Dameron/Kaiser contract did not seek to avail itself of the Parnell court’s guidance.
    Instead, the Dameron/Kaiser contract is silent as to whether Dameron may collect from
    tortfeasors and their automobile insurers after receiving negotiated rate payments from
    the patients’ health care service plans. Dameron attempts to supply the contract term
    by relying on a history of “uniform conduct” in which Dameron and Kaiser have
    cooperated in seeking payment from third party tortfeasors and their liability insurers.
    We conclude the Dameron/Kaiser contract does not contain the term described by
    the Parnell court as sufficient to preserve the right to recover the customary billing rate
    for emergency room services from third party tortfeasors.3 To paraphrase Parnell, if
    Dameron wishes to preserve its right to recover its customary billing rates through an
    HLA lien, it is free to contract for this right. (Parnell, supra, 35 Cal.4th at p. 611.) But
    Dameron must actually contract for this right. (Ibid.) A history of voluntary cooperation
    with Kaiser does not suffice to avail Dameron of the Parnell court’s guidance on
    reservation of contractual rights under the HLA. Consequently, the trial court properly
    granted summary judgment in favor of AAA and Allstate.
    As to Dameron’s argument that it filed a timely claim relating to patient Rita H.’s
    HLA lien, we affirm the trial court’s dismissal based on the statute of limitations.
    Dameron has not made a sufficient showing of diligence to toll the claim under the
    discovery rule.
    3      In reaching this conclusion, we do not express any opinion on collections carried
    out by a commercial health plan in administering federally funded programs (such as
    Medicare) that may specify who should be deemed the primary payer for treatments
    caused by third-party tortfeasors. (See, e.g., 42 U.S.C. § 1395y(b)(2)(A)(ii).)

    BACKGROUND
    Dameron’s Claims Against AAA and Allstate
    In July 2010, Dameron sued AAA and Allstate for damages as well as injunctive
    and declaratory relief. Dameron’s complaint alleges it gives emergency room care to
    patients regardless of their ability to pay, as required by Health and Safety Code section
    1317. Thus, Dameron provided emergency room services to Denise H.4 and Don P. The
    bill for Denise H. amounted to $1,724 and Don P.’s bill was $3,445. After these patients
    were discharged from the emergency room, Dameron learned each was injured by the
    negligence of a driver insured by Allstate.
    Dameron also provided emergency room services to Rita H., Sara M., and D.S.
    Rita H.’s emergency room bill totaled $33,831.74, Sara M.’s was $1,976, and D.S.’s was
    $2,029.76. After these patients were discharged, Dameron learned they were all injured
    by drivers insured by AAA.
    The record indicates Kaiser provided health insurance for each of these patients
    except Rita H. and D.S. For each of these patient’s emergency room services bills
    Dameron served HLA liens on all entities known to Dameron and who might be liable for
    causing each patient’s injuries. And, for each of these patients, Dameron learned AAA or
    Allstate paid a settlement to the patient without satisfying any part of Dameron’s HLA
    liens. Dameron filed the present action within a year of learning of the settlements and
    judgments.
    Dameron further alleges each of the contracts with health care service plans for the
    patients in this case contains an “applicable rate agreement” that “preserves Dameron’s
    HLA rights, as contemplated by the California Supreme Court in Parnell[, supra, 35
    Cal.4th at p. 611].” Dameron asserts it follows the same procedure in collecting on its
    HLA liens whenever a third party has caused injury to an emergency room patient who
    4      The names of the patients at issue in this case are redacted to protect their privacy.
    6
    has coverage with a health insurer having a rate agreement contract with Dameron.
    Specifically, Dameron bills the full amount of the emergency room costs to the injured
    patient’s health plan per Dameron’s contract with the health plan. Dameron also bills the
    full amount of emergency room costs to the third party tortfeasor and/or tortfeasor’s
    liability insurer by serving an HLA notice under Civil Code section 3045.3.5
    If the tortfeasor, tortfeasor’s liability insurer, or any responsible party pays
    Dameron’s HLA claim before the patient’s health care service plan pays Dameron the
    negotiated rate, Dameron cancels its bill to the patient’s health care service plan.
    However, if the patient’s health plan pays the negotiated rate under the applicable rate
    agreement before any other responsible party pays under the HLA lien, Dameron “holds
    the health plan’s payment in abeyance (as well as any co-payment received from the
    injured patient), pending resolution of Dameron’s HLA claim.” If Dameron recovers
    money on its HLA claim following payment from the patient’s health care service plan,
    Dameron refunds the patient’s copayment and then refunds the health care service plan
    from the proceeds of the HLA lien recovery. If there are any proceeds remaining after
    reimbursements to the patient and patient’s health plans, Dameron keeps the remainder.
    In any event, Dameron does not “attempt to collect or retain more than its reasonable and
    necessary charges in any patient’s account.”
    Dameron’s complaint also alleges payments of settlements and judgments to
    patients while ignoring HLA liens “are not isolated or random events. Rather the HLA
    violations . . . are part of an industry-wide business strategy adopted primarily by
    automobile liability insurers in California . . . and by other similarly situated responsible
    parties under the HLA.” In addition to violating the HLA, Dameron claimed the
    5       In other words, Dameron does not seek to “balance bill” tortfeasors or their
    liability insurers for the difference between the negotiated rates paid by health care
    service plans and the customary rate Dameron would ordinarily charge. Instead,
    Dameron seeks to recover the entirety of its customary rates from the tortfeasors and
    their liability insurers.
    7
    practices also violated the Unfair Competition Law (Bus. & Prof. Code, § 17200 et
    seq.).6
    Motions for Summary Judgment
    AAA and Allstate each moved for summary judgment, arguing Dameron could not
    recover anything under the HLA liens because the underlying debts had been
    extinguished by payments in full by the patients’ health plans. AAA also argued two of
    the three claims asserted by Dameron were time-barred.
    In support of its motion, Allstate introduced the Dameron/Kaiser agreement for the
    provision of hospital services to Kaiser patients. The Dameron/Kaiser contract, effective
    January 1, 1995, provides in pertinent part:
    “3. Member Billing. [¶] (a) Hospital shall look solely to Kaiser Permanente (or
    another responsible payer) for compensation for Hospital Services rendered to Members
    under this Agreement, and, except as expressly provided in this Section, Hospital agrees
    that in no event, including but not limited to non-payment by Kaiser Permanente,
    insolvency or breach of this Agreement, shall Hospital bill, charge, collect a deposit
    from, seek compensation, remuneration or reimbursement from, or have any recourse
    against any Member for Hospital Services provided pursuant to this Agreement. Hospital
    further agrees that this provision shall (i) survive the termination of this Agreement
    regardless of the cause giving rise to termination and shall be construed to be for the
    benefit of the Members, and (ii) supersede any oral or written contrary agreement now
    6       Dameron urges us to consider the judgment entered in an earlier class action
    lawsuit titled Ruacho, et al. v. Dameron Hospital Association (Superior Court
    San Joaquin County (2012) SV231473), not as “controlling authority in any manner” but
    to supply “a historical perspective, because it is part and parcel of the uniform
    performance of the Dameron/Kaiser contract in regard to HLA claims.” We decline to do
    so. As Dameron acknowledges, the trial court’s decision in that case cannot be cited as
    legal authority. (Bolanos v. Superior Court (2008) 
    169 Cal.App.4th 744
    , 761.)
    Moreover, the outcome of the earlier and unrelated case does not constitute evidence in
    this case. (Johnson & Johnson v. Superior Court (2011) 
    192 Cal.App.4th 757
    , 768.)
    8
    existing or hereafter entered into by the parties. [¶] (b) Hospital may assert claims for
    compensation other than claims against Kaiser Permanente, in the following
    circumstances: [¶] (i) Copayments. . . . [¶] (ii) Services After Coverage Exhausted or
    Disallowed. . . . [¶] (iii) No benefit. . . . [¶] (iv) Regular Medicare. . . . [¶] (c)
    Hospital understands and agrees that surcharges against Members are prohibited and
    Kaiser Permanente shall take appropriate action if surcharges are imposed. A surcharge
    is an additional fee which is charged to a Member for a covered Hospital Service but
    which is not approved by the Commissioner of Corporations or provided for under the
    applicable Membership Agreement and disclosed in the Member’s evidence of
    coverage.”
    Dameron opposed summary judgment on grounds the Dameron/Kaiser contract
    allowed collection of the HLA liens against AAA and Allstate. Dameron also asserted its
    claims against AAA were not time-barred because the hospital filed the HLA lien notices
    within a year of discovering the identity of the responsible payers.
    The trial court granted summary judgment in favor of AAA and Allstate. The trial
    court reasoned Kaiser’s payment of an agreed-upon rate for emergency room payments
    extinguished the debt owing to Dameron and had the effect of also extinguishing the
    HLA liens. As to two of the claims against AAA, the trial court found the discovery rule
    did not apply to render the HLA claims timely.
    Dameron timely filed notices of appeal from the judgments of dismissal.
    DISCUSSION
    I
    Standards of Review
    We apply the independent standard of review to the trial court’s order granting
    summary judgment. (Guz v. Bechtel National, Inc. (2000) 
    24 Cal.4th 317
    , 334.) As this
    court has noted, “We review the issues framed by the pleadings to determine the scope of
    the issues tendered and to determine whether the moving party has established facts
    9
    negating the opponent’s claim and justifying a judgment in the moving party’s favor.
    (AARTS Productions, Inc. v. Crocker National Bank (1986) 
    179 Cal.App.3d 1061
    , 1064–
    1065.) In so doing we determine whether the opposition to the motion demonstrates the
    existence of a triable issue of material fact. (Ibid.) We review the evidence in the light
    most favorable to the opposition to the motion, and liberally construe the opposition’s
    evidence, while strictly scrutinizing the successful party’s evidence and resolving any
    evidentiary ambiguities in the opposition’s favor. (Saelzler v. Advanced Group 400
    (2001) 
    25 Cal.4th 763
    , 768.)” (Avidity Partners, LLC v. State of California (2013) 
    221 Cal.App.4th 1180
    , 1192.) We also independently review contractual agreements,
    including the question of whether the language used in a contract is ambiguous.
    (American Alternative Ins. Corp. v. Superior Court (2006) 
    135 Cal.App.4th 1239
    , 1245.)
    Finally, “[w]e are not bound by the trial court’s reasons for granting summary judgment
    because we review the trial court’s ruling, and not its rationale.” (Avidity, supra, at
    p. 1192.)
    II
    The HLA as Interpreted in Parnell
    Dameron’s right to recover its customary rates for emergency room services from
    third party tortfeasors and their liability insurers depends on whether the hospital’s HLA
    liens are extinguished when accepting payments by the emergency room patients’ health
    care service plans. The HLA provides a hospital with a statutory lien against any
    judgment, settlement, or compromise paid by a third party tortfeasor or tortfeasor’s
    liability insurer to a patient who received emergency room care. (Parnell, 
    supra,
     35
    Cal.4th at p. 598; Civ. Code, § 3045.2.) Civil Code section 3045.1 states a hospital that
    “furnishes emergency and ongoing medical or other services to any person injured by
    reason of an accident or negligent or other wrongful act . . . shall, if the person has a
    claim against another for damages on account of his or her injuries, have a lien upon the
    damages recovered, or to be recovered, by the person, or by his or her heirs or personal
    10
    representative in case of his or her death to the extent of the amount of the reasonable and
    necessary charges of the hospital.”
    For the HLA lien to become effective, the hospital must serve written notice of
    “the amount claimed as reasonable and necessary charges” on each person or entity
    “known to the hospital and alleged to be liable to the injured person . . . for the injuries
    sustained prior to the payment of any moneys to the injured person.” (Civ. Code,
    § 3045.3.) The HLA notice must also be served on any known liability insurers
    responsible for the actions of the alleged tortfeasors. (Ibid.) However, the hospital need
    not provide notice of the HLA lien to the emergency room patient. (Parnell, 
    supra,
     35
    Cal.4th at p. 601.)
    Tortfeasors and their liability insurers are required to satisfy the HLA lien at the
    same time as they pay any money to the emergency room patients. As the Parnell court
    explained, “If the tortfeasor pays the injured person ‘after the receipt of the notice as
    provided by [Civil Code] Section 3045.3, without paying to the’ hospital ‘the amount of
    its lien claimed in the notice, or so much thereof as can be satisfied out of 50 percent of
    the moneys due under any final judgment, compromise, or settlement agreement,’ then
    the tortfeasor ‘shall be liable to the’ hospital ‘for the amount of its lien claimed in the
    notice which the hospital was entitled to receive as payment for the medical care and
    services rendered to the injured person.’ ([Civ. Code,] § 3045.4.)” (Parnell, 
    supra,
     35
    Cal.4th at pp. 601-602.) This statutory penalty payment to the hospital does not come
    from recovery of funds paid to the injured patient, but must be paid separately by the
    tortfeasor or tortfeasor’s liability insurer. (Mercy Hospital & Medical Center v. Farmers
    Ins. Group of Companies (1997) 
    15 Cal.4th 213
    , 221.)
    The HLA creates a statutory lien that “is ‘nonconsensual’ and ‘compensates a
    hospital for providing medical services to an injured person by giving the hospital a direct
    right to a certain percentage of specific property, i.e., a judgment, compromise, or
    settlement, otherwise accruing to that person.’ (Ibid.)” (Parnell, supra, 
    35 Cal.4th at
    11
    p. 602.) Parnell further notes that, “[a]s a general rule, ‘[a] lien is a charge imposed in
    some mode other than by a transfer in trust upon specific property by which it is made
    security for the performance of an act.’ ([Civ. Code,] § 2872.) Because ‘[a] security
    interest cannot exist without an underlying obligation’ (Alliance Mortgage Co. v.
    Rothwell (1995) 
    10 Cal.4th 1226
    , 1235), a lien is typically ‘but an incident of the debt
    secured’ (Lewis v. Booth (1935) 
    3 Cal.2d 345
    , 349) and ‘presupposes the existence of a
    debt’ (Dorr v. Sacred Heart Hosp. (1999) 
    228 Wis.2d 425
    , 
    597 N.W.2d 462
    , 470
    (Dorr)).” (Parnell, 
    supra,
     
    35 Cal.4th 595
    , 602-603.)
    The typical dependence of a lien on an underlying debt led the Parnell court to
    conclude payment of the underlying debt –- such as by an injured patient’s health plan –-
    extinguished the hospital’s HLA lien. (Parnell, 
    supra,
     
    35 Cal.4th 595
    , 602-603.) Thus, a
    hospital’s acceptance of “payment in full” from a health care service plan relieved the
    third party tortfeasor and his or her liability insurer from any further payment under the
    HLA. (Ibid.) However, the Parnell court noted hospitals could contractually preserve
    the right to recover their usual and customary rates from tortfeasors and their liability
    insurers. Parnell states that “[i]f hospitals wish to preserve their right to recover the
    difference between usual and customary charges and the negotiated rate through a lien
    under the HLA, they are free to contract for this right.” (Id. at p. 611.) Parnell further
    noted neither the Insurance Code nor the Health and Safety Code “precludes hospitals
    from contractually preserving their right to recover ‘reasonable and necessary charges’
    pursuant to a lien under the HLA.” (Id. at p. 611, fn. 15.)
    The Parnell court’s unanimous conclusion that hospitals can contractually reserve
    the right to recover customary emergency room billing rates from third party tortfeasors
    delineates the extent of its holding that a hospital’s acceptance of payment in full from a
    health care services plan extinguishes any HLA lien premised on the same debt.
    (Parnell, supra, 35 Cal.4th at p. 611 & fn. 16 [noting its “holding relies solely on the
    absence of a debt underlying the lien” and does not extend to resolving issues of whether
    12
    the HLA applies in the Medicaid context, violates due process, is subject to waiver by
    hospitals, or is subject to litigation immunity].) Contrary to respondents’ suggestion,
    Parnell’s statements regarding the availability of contractual remedies for hospitals were
    not mere dicta. The Parnell court’s guidance regarding contractual options “was
    responsive to the issues raised on appeal and was intended to guide the parties” and lower
    courts in addressing HLA issues in the future. (Garfield Medical Center v. Belshé (1998)
    
    68 Cal.App.4th 798
    , 806.) We are bound to follow the Supreme Court’s holdings. (Auto
    Equity Sales, Inc. v. Superior Court (1962) 
    57 Cal.2d 450
    , 455.)
    In holding California hospitals may contractually reserve the right to recover their
    customary billing rates from third party tortfeasors, the Parnell court cited the example of
    Andrews v. Samaritan Health System (Ct.App. 2001) 
    36 P.3d 57
    , 61 (Andrews),
    disapproved on another ground in Blankenbaker v. Jonovich (2003) 
    205 Ariz. 383
    , 385-
    386, 
    71 P.3d 910
    , 912-913.7 (Parnell, 
    supra,
     35 Cal.4th at p. 611.) In Andrews, the
    Arizona Court of Appeals held injured patients could not prevent hospitals from balance
    billing by enforcing statutory medical liens on judgments received from third-party
    tortfeasors. (Andrews, 
    supra, at p. 59
    .) In so holding, the Andrews court provided two
    rationales. (Id. at p. 61.) One rationale was Arizona Revised Statutes, section 33–931,
    automatically created a medical lien providing that “a [hospital] provider ‘is entitled to a
    lien for the customary charges for care and treatment . . . of an injured person’ without
    specifying further action by the hospitals.” (Andrews, supra, at p. 61.)
    The other rationale in Andrews arose from the language of the contracts between
    the defendant hospitals and the patients’ health care services plans. Andrews explained
    that “the instant contracts each contained language stating that the hospitals accepted the
    7     Remarkably, none of the parties nor amici curiae mentions Andrews, supra, 
    36 P.3d 57
     in any of their extensive briefing on the meaning and continuing validity of
    Parnell’s holding hospitals have the ability to contractually retain their right to seek their
    customary rates for emergency room services.
    13
    plaintiffs’ insurer’s payment as ‘payment in full,’ and all . . . expressly reserved the
    right to recapture the difference between any payments made by the insurer and the
    providers’ customary charges. Unlike the contracts in the cases from other jurisdictions,
    this reservation clearly qualifies the ‘payment in full’ language and sets forth the
    hospitals’ expectation to recover their customary charges when possible.” (Andrews,
    
    supra,
     36 P.3d at pp. 60-61, italics added.) As a consequence, “[t]he fact that the
    hospitals have no personal recourse against plaintiffs, by virtue of their insurance
    coverage, does not alter the fact that a debt remains between the hospitals’ customary
    charges and the amounts paid by plaintiffs’ insurers.” (Id. at p. 61.) This contract-based
    rationale for preserving a hospital’s right to recover its customary charges from third-
    party tortfeasors was cited with approval by the California Supreme Court in Parnell,
    
    supra,
     35 Cal.4th at p. 611.
    Notably, the patients in Andrews, 
    supra,
     
    36 P.3d 57
     did not have their recoveries
    from third party tortfeasors reduced by the hospitals’ ability to recover their customary
    charges when the patients’ health plans paid only a negotiated rate because “[i]n their
    various personal injury suits, plaintiffs all quantified their damages by including the
    hospitals’ full charges for medical services, rather than the discounted amount paid by
    their insurers.” (Andrews, supra, 36 P.3d at p. 59.) In other words, plaintiffs in Andrews
    were able to claim damages in the amount of customary rates based on the express
    contracts between the hospitals and the health care service plans. (Ibid.) The Andrews
    plaintiffs nonetheless argued the hospitals’ reservation of rights to customary rates
    constituted an unfair assignment of their personal injury claims against the third party
    tortfeasors. The Andrews court rejected the argument, explaining that “[t]he legislature,
    in limited circumstances, may abrogate the rule against assigning tort claims. [Citation.]
    The medical lien statute represents the legislature’s abrogation of that rule. The
    abrogation effected by the medical lien statute serves to ease the financial burden on
    providers and to encourage hospitals to render emergency care to patients without
    14
    regard to ability to pay. [Citation.] Here, the plaintiffs’ insurers did not assign any
    rights to the hospitals. Rather, the right to the medical liens springs from [Arizona
    Revised Statutes] § 33–931. We see no reason to invalidate the medical lien statute as
    written by the legislature given its obvious value and purpose.” (Andrews, 
    supra, at p. 63
    .)
    Taken together, Parnell, 
    supra,
     
    35 Cal.4th 595
     and Andrews allow for statutory
    medical liens to recover customary billing rates for emergency room services if the
    hospital has an express contract with the health care service plan to that effect.
    III
    Parnell’s Continuing Validity
    AAA and Allstate argue Parnell, 
    supra,
     
    35 Cal.4th 595
     is no longer valid authority
    for the proposition that hospitals can contractually reserve the right to recover their
    customary rates even after being paid the negotiated rate by injured patients’ health plans.
    In so arguing, AAA and Allstate rely on the Knox-Keene Health Care Service Plan Act of
    1975 (Knox-Keene Act) (Health & Saf. Code, § 1340 et seq.) and the California Supreme
    Court’s subsequent decisions in Prospect, 
    supra,
     
    45 Cal.4th 497
     and Howell, 
    supra,
     
    52 Cal.4th 541
    . We conclude these authorities do not undermine Parnell’s holding that
    hospitals may contractually preserve their right to recover their customary rates from
    third party tortfeasors and their liability insurers.
    California hospitals are required to provide emergency care without regard to the
    injured patient’s ability to pay. (Health & Saf. Code, § 1317, subd. (d).) The treating
    hospital may require only that “the patient or his or her legally responsible relative or
    guardian . . . execute an agreement to pay therefor or otherwise supply insurance or credit
    information promptly after the services are rendered.” (Ibid.) The Knox-Keene Act
    requires health plans to reimburse hospitals for emergency care even if the hospital is not
    included in the health care service plan’s network. (Health & Saf. Code, § 1371.4,
    subds. (a) & (d).)
    15
    The Knox-Keene Act also includes the following patient-protection provisions:
    “(a) Every contract between a plan and a provider of health care services shall be in
    writing, and shall set forth that in the event the plan fails to pay for health care services
    as set forth in the subscriber contract, the subscriber or enrollee shall not be liable to
    the provider for any sums owed by the plan. [¶] (b) In the event that the contract has
    not been reduced to writing as required by this chapter or that the contract fails to contain
    the required prohibition, the contracting provider shall not collect or attempt to collect
    from the subscriber or enrollee sums owed by the plan. [¶] (c) No contracting provider,
    or agent, trustee or assignee thereof, may maintain any action at law against a subscriber
    or enrollee to collect sums owed by the plan.” (Health & Saf. Code, § 1379 (Section
    1379).)
    We reject the contentions of AAA and Allstate that section 1379 insulates them
    from balance billing by hospitals. Section 1379 does not mention balance billing,
    third party tortfeasors, or liability insurance companies. Instead, the statute mentions
    only health care service plans, providers of medical care, and patients. The clear
    import of section 1379 is to protect patients with health care service plan coverage
    from any collection attempts by providers of such medical care as emergency room
    services.
    Section 1379’s patient protections were examined by the California Supreme
    Court in Prospect, 
    supra,
     
    45 Cal.4th 497
    . Prospect involved billing disputes between
    health care service plans and emergency room physicians with whom they did not have
    preexisting contractual relationships. (45 Cal.4th at p. 503.) The health care service
    plans argued the Knox-Keene Act (along with other provisions of law) prevented the
    emergency room physicians from billing the patients for the difference between the bill
    submitted and the amount paid by the health care service plans. (Id. at pp. 501, 505.)
    Thus, the question presented for the Supreme Court was whether the lack of contract
    between the health care service plans and the emergency physicians precluded section
    16
    1379’s prohibition on “balance billing” –- i.e., billing for the difference between the usual
    and customary rate and the negotiated rate paid. (Id. at pp. 505-506.)
    The Prospect court concluded the Knox-Keene Act precludes any attempt to bill
    patients for the amount exceeding the negotiated rate paid by health care service plans.
    (Prospect, 
    supra,
     45 Cal.4th at p. 502.) Instead, the health care service plans and
    emergency room physicians are required to resolve their billing disputes without injecting
    their patients into the process. (Ibid.) On this point, the Prospect court noted that “the
    Legislature contemplated there may be disputes over the amounts owed to noncontracting
    providers such as emergency room doctors, and therefore the Knox–Keene Act requires
    that each [health maintenance organization] ‘shall ensure that a dispute resolution
    mechanism is accessible to noncontracting providers for the purpose of resolving billing
    and claims disputes.’ (§ 1367, subd. (h)(2); see also § 1371.38, subd. (a) [directing the
    Dept. of Managed Health Care to adopt regulations ensuring that each HMO adopt a
    dispute resolution mechanism that is ‘fair, fast, and cost-effective for contracting and
    noncontracting providers’].)” (Prospect, 
    supra, at p. 507
    .) Ultimately, however, “[a]
    patient who is a member of an HMO may not be injected into the dispute.” (Id. at
    p. 502.)
    The California Supreme Court’s decision in Prospect does not mention its earlier
    case of Parnell, 
    supra,
     
    35 Cal.4th 595
    . (See Prospect, 
    supra,
     45 Cal.4th at pp. 497-511.)
    This omission is explained by the fact Prospect did not involve any claim of recovery
    against third party tortfeasors or their liability insurers. (Ibid.) “An opinion is not
    authority for a point not raised, considered, or resolved therein.” (Styne v. Stevens (2001)
    
    26 Cal.4th 42
    , 57.) Nothing in Prospect abrogates Parnell’s holding that hospitals may
    contract with health care service plans to preserve rights to recover customary billing
    rates via HLA liens against third party tortfeasors.
    We reject AAA’s argument that the California Supreme Court’s decision in
    Howell, 
    supra,
     
    52 Cal.4th 541
     overruled its earlier statement in Parnell that hospitals
    17
    may contract with health care service plans to preserve the right to balance bill third party
    tortfeasors. Howell involved the question of whether an injured patient could sue a
    tortfeasor for damages that included the customary charges for emergency room care
    billed by the hospital. (Id. at p. 548.) The Howell court concluded that when the hospital
    has accepted a lesser amount as full payment under the terms of a prior agreement with
    the health care service plan, the injured patient could only recover this negotiated rate.
    (Ibid.)
    Howell explains that “[t]he collateral source rule, which precludes deduction of
    compensation the plaintiff has received from sources independent of the tortfeasor from
    damages the plaintiff ‘would otherwise collect from the tortfeasor’ [citation], ensures that
    plaintiff . . . may recover in damages the amounts her [or his] insurer paid for her [or his]
    medical care. The rule, however, has no bearing on amounts that were included in a
    provider’s bill but for which the plaintiff never incurred liability because the provider, by
    prior agreement, accepted a lesser amount as full payment. Such sums are not damages
    the plaintiff would otherwise have collected from the defendant. They are neither paid to
    the providers on the plaintiff’s behalf nor paid to the plaintiff in indemnity of his or her
    expenses. Because they do not represent an economic loss for the plaintiff, they are not
    recoverable in the first instance.” (Howell, supra, 52 Cal.4th at pp. 548-549.)
    Howell addressed whether a patient could recover the customary billing rate from
    a tortfeasor, whereas this case involves a claim by the hospital against tortfeasors and
    their liability insurers. (Howell, 
    supra,
     52 Cal.4th at p. 548.) In every instance in which
    Howell articulated its holding, the Supreme Court noted the hospital in that case agreed
    the negotiated rate constituted payment in full. (Id. at pp. 548 [collateral source did not
    apply because hospital agreed to accept negotiated rate as full payment], 554 [hospital
    accepted negotiated rate of “$3,600 in full payment for its services to the plaintiff”].)
    Rather than overruling Parnell, the Supreme Court in Howell repeatedly cited its
    earlier decision with approval. In each of the four instances in which Howell cited
    18
    Parnell, the California Supreme Court expressly noted Parnell involved a situation in
    which the hospital accepted a negotiated rate as payment in full. (Howell, supra, 52
    Cal.4th at pp. 554, 557, 558, 563.) For example, the Howell court noted it “reached the
    same conclusion in Parnell . . . , holding the hospital could not assert a lien against a
    patient’s tort recovery for its full bill when it had agreed to accept an insurer’s lesser
    reimbursement as full payment.” (Howell, 
    supra,
     52 Cal.4th at p. 554, italics added.)
    Similarly, Howell reiterated its holding that, “[h]aving agreed to accept the negotiated
    amount as full payment, a provider may not recover any difference between that and the
    billed amount through a lien on the tort recovery. (Parnell . . . , supra, 35 Cal.4th at
    p. 598.)” (Howell, 
    supra,
     52 Cal.4th at p. 558.) Based on the hospital’s acceptance of a
    negotiated rate as payment in full, Howell concluded that “[p]laintiff cannot meaningfully
    be said ever to have incurred the full charges. (See Parnell . . . , supra, 35 Cal.4th at
    p. 609 [where hospital had agreed with plaintiff’s health plan to accept discounted
    amounts as payment in full, plaintiff owed hospital nothing beyond those discounted
    payments] . . . .)” (Howell, 
    supra, at p. 557
    .) In short, Howell does not overrule the
    Parnell court’s statement that hospitals have the ability to enter into agreements with
    health care service plans that preserve the right to recover customary rates from
    tortfeasors for emergency room care provided.
    We are also not persuaded by AAA that its interpretation of Howell, supra, 
    52 Cal.4th 541
     was confirmed in Corenbaum v. Lampkin (2013) 
    215 Cal.App.4th 1308
    (Corenbaum). AAA argues Corenbaum stands for the proposition that “the tortfeasor,
    and by extension his [or her] insurer, is not liable for the delta between what the hospital
    ‘charged’ and what it accepted from the health insurer.” AAA overstates the scope of
    decision in Corenbaum. The Corenbaum court expressly noted that: “As in Howell, the
    medical providers who treated plaintiffs . . . accepted, pursuant to prior agreements, less
    than the full amount of their medical billings as payment in full for their services.”
    (Corenbaum, supra, at p. 1318.) Based on the similarity in the hospitals’ acceptance of
    19
    the negotiated rate as payment in full, Corenbaum holds evidence of the customary rate
    for emergency room services may not be introduced at trial to prove medical expenses or
    noneconomic damages when the hospital accepted full payment in a lesser amount. (Id.
    at p. 1318.)
    Also based on the Supreme Court’s guidance in Howell, the Corenbaum court
    reasoned that “[a]n insured plaintiff incurs no liability for the negotiated rate differential
    and suffers no pecuniary loss in that amount.” (Corenbaum, at p. 1325.) Thus,
    “[e]vidence of the full amount billed . . . is not relevant to the amount of damages for past
    medical expenses if the plaintiff never incurred liability for that amount.” (Id. at
    p. 1327.) As in Howell, the decision in Corenbaum did not involve any action by the
    hospital against the third party tortfeasor or tortfeasor’s liability insurer.
    Based on our survey of decisional authority following the Supreme Court’s
    unanimous decision in Parnell, supra, 
    35 Cal.4th 595
    , we conclude no case undermines
    Parnell’s guidance to hospitals that they may preserve the right to recover from a third
    party tortfeasor the differential between the negotiated rate paid by an injured patient’s
    health care service plan and the customary rate billed for the emergency room services.
    Moreover, neither the HLA nor applicable provisions of Knox-Keene has been amended
    by the Legislature since the Supreme Court’s 2005 decision in Parnell. (Civ. Code, §§
    3045.2, 3045.3, 3045.4 [pertinent HLA statutes]; § 1379 [pertinent Knox-Keene statute].)
    Thus, the Legislature has not changed how the HLA statutory lien operates either in
    substance or procedure since the Parnell court examined the HLA statutory scheme. In
    short, Parnell remains valid insofar as it allows hospitals to contract for a reservation of
    rights to recover from tortfeasors the differential between the negotiated and the usual
    and customary rates for emergency room services provided.8
    8      In so concluding, we are not called to determine whether or to what extent a
    hospital is limited in the amount it asserts to be its “customary rates.” (Cf. Howell, supra,
    52 Cal.4th at p. 551 [limiting economic damages to “any reasonable charges for
    20
    IV
    Whether the Dameron/Kaiser Contract Preserved Dameron’s Right to Recover its
    Customary Emergency Room Rates from Third-party Tortfeasors
    Having concluded Dameron had the prerogative under Parnell, 
    supra,
     
    35 Cal.4th 595
     to enter into a contract to preserve its billing rights against third party tortfeasors
    liable for injuries to its emergency room patients, we consider whether the
    Dameron/Kaiser contract actually preserved such rights. Dameron contends its contract
    with Kaiser suffices to allow it to pursue its customary billing rate from third party
    tortfeasors who injure Kaiser-covered patients.
    In evaluating Dameron’s claim, we apply well-established principles governing
    review of contractual agreements. “The ordinary rules of contract interpretation apply
    equally to contracts of insurance. (Palmer v. Truck Ins. Exchange (1999) 
    21 Cal.4th 1109
    , 1115.) The mutual intention of the contracting parties at the time the contract was
    formed governs. (Civ. Code, § 1636; Palmer, 
    supra, at p. 1115
    .) We ascertain that
    intention solely from the written contract if possible, but also consider the circumstances
    under which the contract was made and the matter to which it relates. (Civ. Code,
    §§ 1639, 1647.) We consider the contract as a whole and interpret the language in
    context, rather than interpret a provision in isolation. (Id., § 1641.) We interpret words
    in accordance with their ordinary and popular sense, unless the words are used in a
    technical sense or a special meaning is given to them by usage. (Id., § 1644.) If
    contractual language is clear and explicit and does not involve an absurdity, the plain
    meaning governs. (Id., § 1638.)” (American Alternative Ins. Corp. v. Superior Court
    (2006) 
    135 Cal.App.4th 1239
    , 1245.)
    Here, the Dameron/Kaiser contract was entered into in 1995, a decade before the
    California Supreme Court issued its decision in Parnell, 
    supra,
     
    35 Cal.4th 595
    . The
    treatment the injured person has paid or, having incurred, still owes the medical provider
    are recoverable as economic damages”], italics added.)
    21
    contract does not expressly reserve to Dameron a right to recover its customary billing
    rates for emergency room services from anyone. The Dameron/Kaiser contract does not
    mention HLA liens, third party tortfeasors, or liability insurers for third party tortfeasors.
    Instead, the contract sets forth the reciprocal obligations of Dameron to provide
    emergency medical services and Kaiser to pay negotiated rates for those services.9
    Rather than reserving the right to recover the entirety of the customary charge from third
    party tortfeasors, the Dameron/Kaiser contract states payment of the negotiated rates
    constitutes payment in full. Exhibit A of the Dameron/Kaiser contract provides:
    “[Kaiser] will pay [Dameron] for Covered Services the rates set forth in this
    Exhibit A, reduced by applicable Copayments . . . . [Dameron] will accept such amounts
    as payment in full for Covered Services, irrespective of the cost to [Dameron] of
    providing such services, or of [Dameron]’s customary charges for such services.” (Italics
    added.)
    This contract provision does not reserve to Dameron any right to recover
    additional payments from any other person or entity. Moreover, it imposes on Kaiser no
    obligation to assist or take any other action to help Dameron recover its customary
    charges from any third party tortfeasor or liability insurer. And, there is no mention of
    HLA liens. To escape this express agreement to accept the negotiated rate as “payment
    in full,” Dameron looks to the “Member Billing” section of the contract. Specifically,
    Dameron points to language stating that “Hospital shall look solely to Kaiser Permanente
    (or another responsible payer) for compensation for Hospital Services rendered to
    Members under this Agreement.” (Italics added.)
    9      In the copy of the Dameron/Kaiser contract filed in the trial court, the pages
    specifying the negotiated billing rates are marked “with[h]eld as proprietary trade secret
    info.” Even so, the parties agree the contract supplied Kaiser with negotiated billing rates
    for emergency room services that were less than Dameron’s customary rates for the same
    services.
    22
    Dameron argues the italicized language renders this contract provision sufficiently
    ambiguous to allow extrinsic evidence to prove that “another responsible payer” includes
    tortfeasors and their liability insurers. A contract is ambiguous when it contains language
    that is reasonably susceptible to more than one meaning. (MacKinnon v. Truck Ins.
    Exchange (2003) 
    31 Cal.4th 635
    , 648.) For several reasons, the contract’s reference to
    “another responsible payer” cannot reasonably be construed to refer to third party
    tortfeasors or their liability insurers.
    First, the reference to another responsible payer is qualified by the restriction that
    Dameron is limited to “compensation for Hospital Services rendered to Members under
    this Agreement.” (Italics added.) The purpose of the Dameron/Kaiser contract is to agree
    upon negotiated billing rates and to insulate patients covered by Kaiser from charges
    beyond their individual copayment responsibilities. Under this agreement, there is no
    mention of customary billing rates or HLA liens.
    Second, the paragraphs immediately following language cited by Dameron serve
    to limit Dameron’s “claims for compensation” to copayments, services after coverage is
    exhausted or disallowed by Kaiser, instances in which the patient turns out to have no
    Kaiser coverage at all, and “regular Medicare.” Even if the meaning of “another
    responsible payer” were ambiguous, these paragraphs preclude any interpretation of the
    phrase to include third party tortfeasors or their liability insurers.
    Third, any interpretation of “another responsible payer” as including third party
    tortfeasors would create a conflict with the portion of the Dameron/Kaiser contract in
    which Dameron has agreed to accept the negotiated rates “as payment in full for Covered
    Services, irrespective of the cost to [Dameron] of providing such services.” (Italics
    added.) We reject this interpretation as introducing an unnecessary internal inconsistency
    into the Dameron/Kaiser contract. “It is a cardinal rule of construction that a contract is
    to be construed as a whole, effecting harmony among and giving meaning to all the parts
    23
    thereof. (Civ. Code, § 1641.)” (People ex rel. Dept. of Parks and Recreation v. West-A-
    Rama, Inc. (1973) 
    35 Cal.App.3d 786
    , 793.)
    Fourth, Dameron’s assertion of the ability to collect customary rates from other
    parties would have the effect of imposing new duties on Kaiser that are not otherwise
    spelled out in the contract. In its briefing, Dameron contends we should accept a history
    of cooperation between Dameron and Kaiser in pursuing additional payments from third
    party tortfeasors. In other words, Dameron argues Kaiser has a contractual duty to assist
    in recovering the customary billing rates for its patients from others. Crediting this
    argument would mean Dameron could sue Kaiser for breach of contract if that health care
    service plan did not help pursue Dameron’s HLA liens. The Dameron/Kaiser contract
    spells out no such obligation for Kaiser.
    The Dameron/Kaiser contract’s silence as to any obligation to assist in collection
    from third party tortfeasors does not allow us to graft a new obligation into the
    agreement. Indeed, the contract itself provides that “[a]ny other agreements, promises,
    negotiations, or representations relating to the subject matter of this Agreement . . . not
    expressly set forth herein are of no force and effect.” “Courts will not add a term about
    which a contract is silent. (Moss Dev. Co. v. Geary (1974) 
    41 Cal.App.3d 1
    , 9.)” (Levi
    Strauss & Co. v. Aetna Casualty & Surety Co. (1986) 
    184 Cal.App.3d 1479
    , 1486
    dismissed, remanded and ordered published sub nom. Levi Strauss and Co. v. Aetna
    Cas. and Sur. Co. (1987) [
    237 Cal.Rptr. 455
    ].) Instead, “[a] contract extends only
    to those things which it appears the parties intended to contract. Our function is to
    determine what, in terms and substance, is contained in the contract, not to insert what
    has been omitted. We do not have the power to create for the parties a contract that
    they did not make and cannot insert language that one party now wishes were there.”
    (Vons Companies, Inc. v. United States Fire Ins. Co. (2000) 
    78 Cal.App.4th 52
    , 58-59.)
    Dameron correctly points out that “[n]either law nor equity requires that every
    term and condition be set forth in a contract.” (Frankel v. Board of Dental Examiners
    24
    (1996) 
    46 Cal.App.4th 534
    , 545.) Thus, “usual and reasonable terms found in similar
    contracts may be considered, unexpressed provisions of the contract may be inferred
    from the writing, external facts may be relied upon, and custom and usage may be
    resorted to in an effort to supply a deficiency if it does not alter or vary the terms of the
    agreement.” (Ibid.) However, supplying implied terms to give effect to the expressed
    intent of the contract does not allow us to impose new duties and obligations to which the
    parties never agreed. “[C]ourts cannot make better agreements for parties than they
    themselves have been satisfied to enter into or rewrite contracts because they operate
    harshly or inequitably. It is not enough to say that without the proposed implied
    covenant, the contract would be improvident or unwise or would operate unjustly.
    Parties have the right to make such agreements. The law refuses to read into contracts
    anything by way of implication except upon grounds of obvious necessity.” (Ibid.)
    Although Parnell, supra, 
    35 Cal.4th 595
     allows Dameron to contractually reserve
    the right to recover its customary billing rate for emergency room services for Kaiser
    patients and caused by third party tortfeasors, Dameron has not done so in this case. 10
    10     We note the summary judgments in favor of AAA and Allstate included claims
    pertaining to emergency room patients covered by health care service plans other than
    Kaiser. In the trial court, Dameron argued summary judgment could not be granted in
    favor of AAA and Allstate because their motions did not seek to dispose of all claims.
    The trial court granted summary judgment in favor of AAA and Allstate concluding
    claims involving Kaiser patients failed for lack of a debt underlying Dameron’s lien
    claims. As to the non-Kaiser patients, the trial court found Dameron had not amended
    the complaint to include these claims. In this appeal, Dameron does not contend the trial
    court erred in dismissing the claims for five non-Kaiser patients. Accordingly, we affirm
    also as to the trial court’s dismissal of claims premised on these five patients not covered
    by Kaiser.
    Finally, we do not address whether the billing scheme asserted by Dameron to be
    its contractually reserved right complies with California law by reimbursing Kaiser for
    the entirety of its payments if Dameron recovers the full customary billing rate from a
    third party tortfeasor or tortfeasor’s liability insurer.

    V
    Whether Dameron Timely Asserted HLA Lien Claims for Emergency Room Services
    Provided to Rita H.
    Dameron contends the trial court erred finding the one-year statute of limitations
    rendered untimely Dameron’s claim against AAA for patient Rita H. Specifically,
    Dameron argues the delayed discovery rule applied to render its HLA claim timely. We
    disagree.
    A.
    Trial Court Ruling on the Claims Relating to Rita H.’s Care
    In moving for summary judgment, AAA argued that Dameron’s claims --
    including those relating to Rita H. -- were untimely because they were filed after the
    expiration of the one-year statute of limitations imposed by Civil Code section 3045.5.11
    Dameron opposed the motion and introduced a declaration by its credit and collections
    manager, Craig Haupt. In pertinent part, Haupt declared:
    “Dameron acts diligently to attempt to discover whether a payor (such as AAA)
    has violated the HLA. In doing so, agents of Dameron regularly call entities involved in
    the underlying personal injury claim (auto insurers such as AAA, attorneys for claimants,
    known attorneys for tortfeasors, known tortfeasors, etc.), to attempt to learn, via both
    telephone and written correspondence, whether a payment has been made in violation of
    the HLA. In many instances it is difficult, however, for Dameron, despite its diligence to
    learn of a violation of the HLA. It is only through great determination and persistence
    that Dameron learns of violations of its HLA liens. Accordingly, Dameron often learns
    11     Civil Code section 3045.5 provides: “The person, partnership, association,
    corporation or other institution or body maintaining the hospital may, at any time within
    one year after the date of the payment to the injured person, or to his [or her] heirs,
    attorney, or legal representative, enforce its lien by filing an action at law against the
    person, firm, or corporation making the payment and to whom such notice was given as
    herein provided.” (Italics added.)
    26
    that an HLA lien has been paid around over a year after the payment around the lien has
    been made. When this situation arises, Dameron moves swiftly to enforce its HLA lien
    rights. [¶] . . . With respect to all of the claims discussed by AAA in its motion, and
    indeed, all of the claims at issue in this action against AAA, Dameron has filed suit
    within a year of discovering that AAA violated the HLA by ignoring and paying around
    Dameron’s liens.”
    The trial court dismissed Dameron’s claim relating to Rita H. as untimely and
    explained: “The filing of this Complaint . . . occurred more than one year after the ‘first
    account’ and ‘second accounts’ were resolved by AAA. [¶] . . . [¶] Dameron argues that
    the discovery rule should apply to extend the running of the statute of limitations because
    Dameron is often not aware of insurers’ settlements with tortfeasors and has to pursue
    this information by calling or writing involved insurers, counsel, or claimants.” The trial
    court rejected Dameron’s argument, explaining: “Dameron offers no evidence of any
    fiduciary relationship nor of any specific representations or misrepresentations made to it,
    and that it relied upon, justifying imposition of an estoppel or a delayed discovery rule. It
    admits that it pursued information regarding settlements, but did not always receive that
    information in a timely fashion, but it does not provide evidence specific to the two
    claims alleged to be untimely here. Accordingly, the court declines to apply the delayed
    discovery rule to these facts.”
    B.
    The Discovery Rule
    As the California Supreme Court has explained, “Generally speaking, a cause of
    action accrues at ‘the time when the cause of action is complete with all of its elements.’
    (Norgart [v. Upjohn Co. (1999)] 21 Cal.4th [383,] 397; see Neel v. Magana, Olney, Levy,
    Cathcart & Gelfand (1971) 
    6 Cal.3d 176
    , 187 (Neel).) An important exception to the
    general rule of accrual is the ‘discovery rule,’ which postpones accrual of a cause of
    action until the plaintiff discovers, or has reason to discover, the cause of action.
    27
    (Norgart, supra, 21 Cal.4th at p. 397; Neel, supra, 6 Cal.3d at p. 187.) [¶] A plaintiff has
    reason to discover a cause of action when he or she ‘has reason at least to suspect a
    factual basis for its elements.’ (Norgart, supra, 21 Cal.4th at p. 398, citing Jolly [v. Eli
    Lilly & Co. (1988)] 44 Cal.3d [1103,] 1110.)” (Fox v. Ethicon Endo-Surgery, Inc. (2005)
    
    35 Cal.4th 797
    , 806-807 (Fox), fn. omitted.)
    In Fox, the Supreme Court further explained that, “[i]n assessing the sufficiency of
    the allegations of delayed discovery, the court places the burden on the plaintiff to ‘show
    diligence’; ‘conclusory allegations will not withstand demurrer.’ ” (Fox, 
    supra,
     35
    Cal.4th at p. 808, quoting McKelvey v. Boeing North American, Inc. (1999) 
    74 Cal.App.4th 151
    , 160.) On this point, the Sixth District Court of Appeal recently held
    that “[t]he discovery-related facts should be pleaded in detail to allow the court to
    determine whether the [cause of action] should have been discovered sooner.” (Cansino
    v. Bank of America (2014) 
    224 Cal.App.4th 1462
    , 1472.)
    C.
    Dameron’s Showing
    The trial court properly concluded Dameron had not made a sufficient showing of
    diligence to invoke the discovery rule for its HLA claims relating to Rita H. Although
    Dameron professed to have acted “diligently,” it relied on a declaration that failed to
    mention any efforts made to discover payment on the HLA claims relating to Rita H.’s
    care. Not a single phone call, letter, or effort to inquire about the status of Rita H.’s HLA
    lien is mentioned in the Haupt declaration. Instead, Dameron recounted its general
    practices of “regularly” calling and using “great determination and persistence” in
    following up on its HLA liens. However, Dameron’s characterizations of diligence and
    effort do not describe the frequency or specifics even of its normal practices for HLA
    liens. Because conclusory allegations of diligence fail to warrant application of the
    discovery rule, the trial court correctly dismissed Dameron’s claims relating to Rita H.’s
    care.
    28
