    No. 21-AA-0652
    CHRISTOPHER HONEMOND, PETITIONER,
    v.
    D.C. DEPARTMENT OF EMPLOYMENT SERVICES, RESPONDENT,
    and
    GEORGETOWN UNIVERSITY, et al., INTERVENORS.
    On Petition for Review of a Decision and Order of
    the District of Columbia Department of Employment Services
    Compensation Review Board
    (CRB No. 21-054)
    (Argued October 27, 2022                                     Decided June 15, 2023)
    Krista N. DeSmyter for petitioner.
    Karl A. Racine, Attorney General for the District of Columbia (at the time the
    statement was filed), Caroline S. Van Zile, Solicitor General, and Ashwin P. Phatak,
    Principal Deputy Solicitor General, filed a statement in lieu of brief for respondent.
    Jonathan M. Marlin for intervenors.
    Before BLACKBURNE-RIGSBY, Chief Judge, DEAHL, Associate Judge, and
    FISHER, Senior Judge.
    2
    BLACKBURNE-RIGSBY, Chief Judge: Petitioner Christopher Honemond filed
    a workers’ compensation claim for disability benefits stemming from a work
    incident that occurred on June 30, 2016. Intervenors are Mr. Honemond’s employer,
    Georgetown University, and its insurance carrier, Travelers Insurance Company.
    Previously, this court affirmed a compensation order on remand concluding that Mr.
    Honemond had failed to establish that he has a disabling mental condition causally
    related to the work incident. Honemond v. D.C. Dep’t of Emp. Servs., No. 18-AA-
    635, Mem. Op. & J. (D.C. July 29, 2019).
    Mr. Honemond sought modification of this order, pursuant to 
    D.C. Code § 32
    -
    1524 (“Modification of awards”). In his modification claim, he alleged that he
    suffers from Post-Traumatic Stress Disorder (“PTSD”), Panic Disorder, and
    Generalized Anxiety Disorder. He separately alleged that he has a permanent partial
    physical disability in his arm. The Administrative Law Judge (“ALJ”) denied both
    claims, concluding that Mr. Honemond had neither shown that a change of
    conditions had occurred as to his mental conditions, nor had he proven that he is
    entitled to disability benefits for his arm.   The Compensation Review Board
    (“CRB”) affirmed the denials. Mr. Honemond now petitions for our review. We
    affirm.
    3
    I.    Background
    A. Previous Workers’ Compensation Claims
    Mr. Honemond was a maintenance mechanic for Georgetown University for
    nearly 30 years. On June 30, 2016, he descended into a manhole on a ladder to shut
    off a steam valve. The manhole was very hot because the steam lines were
    uninsulated. Overcome by the heat, Mr. Honemond had to leave the manhole. As
    he ascended, he brushed his left forearm against the ladder and sustained a burn.
    Mr. Honemond went to the emergency room at Medstar Georgetown
    University Hospital that same day. The emergency room nurse reported that she did
    not observe redness or other skin changes on Mr. Honemond’s arm but noted that
    Mr. Honemond reported pain and tingling. The emergency room discharge report
    directed Mr. Honemond to use over-the-counter pain medicine and ointment on the
    site and to follow-up with his primary care doctor.        Shortly thereafter, Mr.
    Honemond visited his primary care doctor and then an orthopedist, who referred him
    to a burn management specialist.
    4
    Mr. Honemond went to outpatient treatment at the Medstar Washington
    Hospital Center Burn Center. Occupational therapist Rebekah Allely assessed Mr.
    Honemond for an occupational therapy evaluation. She reported that she did not see
    any redness, discoloration, or scarring on Mr. Honemond’s arm. Mr. Honemond
    then completed a short course of physical therapy with Ms. Allely. On the last visit,
    Ms. Allely reported that Mr. Honemond “does not appear to have physical
    limitations at this time” and that, while he had some diminished grip strength in his
    left arm, “it is well within functional norms.” She concluded that Mr. Honemond
    did not have further occupational therapy needs. Mr. Honemond did not seek out
    treatment for his arm after this August 2016 visit.
    In December 2016, Dr. Brian Schulman prepared an independent medical
    examination on behalf of intervenors. Dr. Schulman opined, to a reasonable degree
    of medical certainty, that Mr. Honemond had not sustained a psychiatric or mental
    disorder from the June 2016 event. Around this time, Mr. Honemond began
    treatment with psychiatrist Dr. Patrick Sheehan. On April 10, 2017, Dr. Sheehan
    diagnosed Mr. Honemond with PTSD, Depressive Disorder, and Panic Disorder
    causally related to the work incident.
    5
    Mr. Honemond filed a claim for workers’ compensation benefits in May
    2017. 1 He sought temporary total disability benefits, claiming that he had developed
    PTSD, Depressive Disorder, and Panic Disorder as a result of the work incident.
    The ALJ resolved these claims in a January 2018 compensation order on remand.2
    The ALJ did not credit Dr. Sheehan’s diagnoses and instead credited Dr. Schulman,
    who opined that Mr. Honemond did not meet the criteria for the claimed mental
    conditions. The ALJ concluded that Mr. Honemond failed to establish that he has
    PTSD, Panic Disorder, or Depressive Disorder “causally related” to the work
    incident. The CRB affirmed.
    Mr. Honemond then petitioned this court, which affirmed the CRB’s decision
    by memorandum opinion and judgment. 3 The division determined that the ALJ had
    properly weighed the competing evidence to come to a conclusion that Mr.
    1
    Intervenors voluntarily paid temporary total disability benefits from July 5,
    2016 until August 19, 2016.
    2
    The ALJ first denied this claim on August 31, 2017, but the CRB remanded
    so that the ALJ could make explicit credibility findings.
    3
    Honemond v. D.C. Dep’t of Emp. Servs., No. 18-AA-635, Mem. Op. & J.
    (D.C. July 29, 2019).
    6
    Honemond did not suffer from a disabling mental condition causally related to his
    employment.
    B. Workers’ Compensation Claims On Appeal
    Mr. Honemond applied for modification of the compensation order on
    remand, pursuant to 
    D.C. Code § 32-1524
    (a). Mr. Honemond alleged that he had
    experienced a “change of conditions” as to PTSD, Panic Disorder, and Generalized
    Anxiety Disorder. Mr. Honemond also requested benefits for permanent partial
    disability and temporary total disability for his left arm. 4
    At a status conference, the ALJ granted Mr. Honemond 48 hours to decide
    whether he wanted to present live testimony regarding his modification claim. Mr.
    Honemond did not express desire to present live testimony until over a week late.
    Intervenors objected, arguing that they had already begun work on their brief. The
    ALJ determined that the parties would submit on their briefs and allowed Mr.
    Honemond to proffer facts he had expected to elicit through live testimony.
    4
    There was no contest to the timeliness of these claims.
    7
    In his brief to the ALJ on these issues, Mr. Honemond proffered that “his
    condition has worsened” and that his panic attacks “returned and waxed and waned
    over time.” He proffered that he “has an array of different but worse complaints in
    2020 than he had in 2017.” He represented that he had begun treatment with a
    licensed clinical social worker, Penny Zimmerman, and that he had gone to the
    emergency room in August 2019 for “panic symptoms.” He represented that Ms.
    Zimmerman had “noted” that he suffered from PTSD and Panic Disorder, and that
    his symptoms of panic and insomnia were “more intense,” but he did not offer
    corroborating evidence. He also represented that Dr. Sheehan had diagnosed him
    with PTSD, an unspecified Depressive Disorder, Panic Disorder, and an alcohol use
    disorder on September 30, 2019. He did not provide updated medical records from
    Dr. Sheehan. He also represented generally that he had “updated psychiatric
    records” but did not provide them.
    The ALJ denied Mr. Honemond’s modification claim. The ALJ concluded
    that the PTSD and Panic Disorder claims had been previously litigated and that Mr.
    Honemond had shown no “reason to believe” that a change of conditions as to these
    claims had occurred.5 The ALJ also concluded that Mr. Honemond had not shown
    5
    Though he referenced it in his proffer, Mr. Honemond did not raise
    Depressive Disorder as a condition in his modification claim.
    8
    that he has Generalized Anxiety, as he provided no medical records and had not
    proffered that he had been diagnosed with that condition.
    The ALJ then held a hearing regarding the nature and extent of Mr.
    Honemond’s disability in his left arm. Mr. Honemond was the sole witness and
    testified that he was experiencing pain and trouble with strength and functionality.
    Both parties offered records from Mr. Honemond’s 2016 visit to the emergency
    room, follow-up appointments with his primary care doctor and an orthopedist, and
    treatment and occupational therapy at the Burn Center.
    The ALJ admitted the report of Dr. Joel Fechter, who had performed an
    evaluation of Mr. Honemond’s arm on December 5, 2019. In his report, Dr. Fechter
    concluded, to a reasonable degree of medical certainty, that Mr. Honemond had a
    total impairment of 19% of his left arm. Dr. Fechter opined that the reported
    “weakness” in Mr. Honemond’s arm entitled Mr. Honemond to 10% impairment,
    and that Mr. Honemond was also entitled to an additional 2% for each subjective
    factor of reported “pain, loss of endurance, and loss of function.” He erroneously
    added these figures up to a 19% impairment instead of 16%.
    9
    The ALJ also admitted intervenors’ report from Dr. Marc Danziger, who
    performed an independent medical evaluation of Mr. Honemond’s arm on October
    19, 2020. Dr. Danziger scored Mr. Honemond as 0% impaired because he had
    “normal sensory and motor function,” a “full range of motion,” and “completely
    normal skin turgor, function, and no sensory changes, scarring or abnormality[.]”
    Dr. Danziger determined that Mr. Honemond had only a “heat episode to the left
    forearm,” as no treating physician had noted any symptom “that would classify as
    even a first degree burn.”
    The ALJ concluded that Mr. Honemond had not proven, by a preponderance
    of the evidence, that he was entitled to any disability benefits for his arm. The ALJ
    rejected Dr. Fechter’s report as “unreliable.”
    Mr. Honemond appealed both the November 2020 order regarding mental
    conditions and the February 2021 order regarding physical disability to the CRB,
    which partially affirmed and partially remanded.        The CRB agreed that Mr.
    Honemond’s mental condition claims were barred because Mr. Honemond had not
    shown evidence of a new diagnosis or new symptoms. The CRB next determined
    that the compensation order contained insufficient findings of fact and analysis as to
    the claimed physical disability.
    10
    The ALJ then issued a compensation order on remand. The ALJ concluded
    again that Mr. Honemond failed to prove, by a preponderance of the evidence, that
    he is entitled to disability benefits for his arm. The ALJ explained that Dr. Fechter’s
    report was “rejected” for four reasons. First, the ALJ explained that the report was
    “unreliable” because its rating was based on subjective complaints from Mr.
    Honemond, whom the ALJ found unreliable as to the nature and extent of his injury.
    Second, the ALJ explained that Dr. Fechter’s report was unreliable because it lacked
    meaningful explanation. Third, the ALJ explained that basic math errors in Dr.
    Fechter’s report suggested inattentiveness. Finally, the ALJ explained that these
    math errors made it difficult to discern both the actual rating and the components of
    the rating. The ALJ instead credited Dr. Danziger’s report, and his 0% impairment
    rating, as persuasive and reliable because the report was based on objective factors
    and was sufficiently explained.
    Mr. Honemond appealed to the CRB again. The CRB affirmed the denial of
    permanent partial disability. The CRB explained that the ALJ made sufficient
    additional findings of fact to support the conclusion that Dr. Fechter’s report and
    opinions were unreliable. The CRB also found that the ALJ sufficiently explained
    why Dr. Danziger’s report was credited as persuasive.
    11
    Mr. Honemond timely petitioned this court for review. Before us now are the
    April 2021 decision of the CRB, which affirmed the denial of the modification claim,
    and the August 2021 decision of the CRB, which affirmed the denial of the
    permanent partial disability claim.
    II.    Discussion
    Review of a final order of the CRB is limited to determining whether the
    decision is “arbitrary, capricious, an abuse of discretion, or otherwise not in
    accordance with law.” Reyes v. D.C. Dep’t of Emp. Servs., 
    48 A.3d 159
    , 164 (D.C.
    2012) (internal quotation marks omitted). Though the court’s review is of the CRB’s
    decision, we do not “ignore the compensation order which is the subject of the
    Board’s review.” Georgetown Univ. Hosp. v. D.C. Dep’t of Emp. Servs., 
    916 A.2d 149
    , 151 (D.C. 2007). In conducting a review, we first decide “whether the agency
    has made a finding of fact on each material contested issue of fact; second, whether
    the agency’s findings are supported by substantial evidence on the record as a whole;
    and third, whether the [Board’s] conclusions flow rationally from those findings and
    comport with the applicable law.” 
    Id.
     (quoting Mills v. D.C. Dep’t of Emp. Servs.,
    12
    
    838 A.2d 325
    , 328 (D.C. 2003)). A review of the CRB’s legal rulings is de novo.
    Reyes, 
    48 A.3d at 164
    .
    A.     Modification
    Mr. Honemond argues that the CRB erred in affirming the determination that
    he had not demonstrated a reason to believe that there has been a change of condition
    as to claimed mental disabilities. We disagree. Mr. Honemond neither made an
    adequate proffer of facts, nor provided adequate medical evidence, to support his
    assertion that a “change of condition” occurred.
    The principles of res judicata and collateral estoppel apply in administrative
    agency proceedings when “the earlier proceeding is the essential equivalent of a
    judicial proceeding.” Oubre v. D.C. Dep’t of Emp. Servs., 
    630 A.2d 699
    , 703 (D.C.
    1993) (quoting William J. Davis, Inc. v. Young, 
    412 A.2d 1187
    , 1194 (D.C. 1980)).
    “After a valid final adjudication on the merits, the doctrine of res judicata bars
    relitigation of the same claim between the same parties. Collateral estoppel, a related
    doctrine, precludes relitigation of issues of fact or law determined in a prior
    proceeding which were essential to that judgment.” 
    Id.
     (internal quotation marks
    and citations omitted).
    13
    The D.C. Workers’ Compensation Act provides a specific procedure in which
    a claimant may “revisit issues previously decided by a compensation order.” Short
    v. D.C. Dep’t of Emp. Servs., 
    723 A.2d 845
    , 850 (D.C. 1998).
    At any time prior to 1 year after the date of the last
    payment of compensation or at any time prior to 1 year
    after the rejection of a claim, . . . the Mayor may, upon his
    own initiative or upon application of a party in interest,
    order a review of a compensation case pursuant to the
    procedures provided in § 32-1520 where there is reason to
    believe that a change of conditions has occurred which
    raises issues concerning:
    (1) The fact or the degree of disability or the amount of
    compensation payable pursuant thereto; or
    (2) The fact of eligibility or the amount of compensation
    payable pursuant to § 32-1509.
    
    D.C. Code § 32-1524
    (a). Thus, a claimant may pursue modification of a previous
    order if there is a “change as to the ‘fact or the degree of disability[.]’” Short, 
    723 A.2d at 850
     (quoting 
    D.C. Code § 32-1524
    (a)(1)); see also Washington Metro. Area
    Transit Auth. v. D.C. Dep’t of Emp. Servs., 
    770 A.2d 965
    , 972 (D.C. 2001)
    (“Young”). “[T]he relevant change is a change in the condition determined to exist
    by the previous factfinder (here, [the ALJ]), not a change from a [medical estimation]
    of the claimant’s condition.” Bowser v. D.C. Dep’t of Emp. Servs., 
    129 A.3d 253
    ,
    260 (D.C. 2015), as amended (Feb. 25, 2016).
    14
    There is a two-step procedure for when a claimant pursues modification of a
    previous order. First, “the agency must conduct a ‘preliminary examination of
    evidence intended to be submitted at an evidentiary hearing[.]’” Bowser, 129 A.3d
    at 258 (quoting Snipes v. D.C. Dep’t. of Emp. Servs., 
    542 A.2d 832
    , 834 n.4 (D.C.
    1988)). This review “shall be limited solely to new evidence which directly
    addresses the alleged change of conditions.” 
    D.C. Code § 32-1524
    (b). But “it seems
    evident that in this determination a hearing examiner must necessarily take into
    account what came before in determining whether a ‘change’ has occurred.” Snipes,
    
    542 A.2d at 835
    . Second, “if that examination reveals ‘evidence which could
    establish, if credited, changed conditions’ (the ‘threshold test’),” then the agency
    must “conduct an evidentiary hearing on the issue of whether there has been a change
    in conditions.” Bowser, 129 A.3d at 258 (quoting Snipes, 
    542 A.2d at 835
    ). The
    “scope of review on these issues requires [us] to decide whether the agency made
    the threshold determination under the statute and whether its determination is
    supported by substantial evidence in the record.” 
    Id.
     (cleaned up).
    As a preliminary matter, we note that the ALJ gave both parties the
    opportunity to present live testimony as to issues implicated by a Snipes inquiry.
    Mr. Honemond was over a week late in informing the ALJ that he wanted to present
    15
    testimony, but he was allowed to proffer facts that he had expected to elicit. We
    have never suggested that the threshold determination requires live testimony. See
    Bowser, 129 A.3d at 258 (explaining only that an ALJ must conduct a “preliminary
    examination of evidence intended to be submitted at an evidentiary hearing”). Thus,
    contrary to his assertions, Mr. Honemond was given an adequate opportunity to
    support his claim for modification. 6
    At the threshold stage, movant must “meet the modest threshold burden of
    producing minimal evidence to support the ‘reason to believe’ standard.”
    Washington Metro. Area Transit Auth. v. D.C. Dep’t of Emp. Servs., 
    703 A.2d 1225
    ,
    1230 (D.C. 1997) (“Anderson”); see also Snipes, 
    542 A.2d at 835
     (“[A] claimant’s
    right to an evidentiary hearing . . . is triggered only where there is reason to believe
    that a change of conditions has occurred.”) (internal quotation marks omitted). This
    is “short of full proof,” but requires “some affirmative factual showing that a change
    of conditions has occurred.” Anderson, 703 A.2d at 1230; see also Quaranta v. D.C.
    Dep’t of Emp. Servs., 
    284 A.3d 389
    , 393 (D.C. 2022) (“That is not an exacting
    standard, but it does require an applicant to produce evidence or at least a proffer
    6
    We also find no merit to Mr. Honemond’s assertion at oral argument that the
    ALJ prevented him from supplementing his claim with exhibits. There is nothing in
    the order suggesting that Mr. Honemond was barred from providing exhibits or
    otherwise presenting corroborating evidence.
    16
    ‘which could establish, if credited, changed conditions’ that might alter their
    disability award.”) (quoting Bowser, 129 A.3d at 258).
    Mr. Honemond failed to put forth any more than generic and conclusory
    proffers regarding his modification claim. As to Generalized Anxiety Disorder, the
    only condition that was not litigated previously, Mr. Honemond provided no medical
    evidence, nor did he even proffer that he had been diagnosed with that condition.
    The CRB correctly determined that “[m]erely claiming a new diagnosis (generalized
    anxiety), with similar symptoms, does not rise to the level of a reason to believe that
    there has been a change in Claimant’s condition that warrants a modification.”
    As to claims of PTSD and Panic Disorder, Mr. Honemond did not present
    sufficient evidence to support a conclusion that he had developed PTSD or Panic
    Disorder causally related to the work incident since the ALJ’s previous findings on
    these issues. See Bowser, 129 A.3d at 260 (explaining that the “relevant change is a
    change in the condition determined to exist by the previous factfinder”).
    Importantly, Mr. Honemond presented no new medical evidence. Though Mr.
    Honemond represented that Dr. Sheehan diagnosed him with PTSD, an unspecified
    Depressive Disorder, Panic Disorder, and an alcohol abuse disorder in September
    2019, there was no accompanying medical record to support this assertion. Based
    17
    on these general proffers, it is also unclear if Dr. Sheehan newly diagnosed Mr.
    Honemond with these conditions or if Dr. Sheehan was merely reiterating his
    diagnoses from 2017—diagnoses which the ALJ found were too insufficiently
    explained and supported to be credible.
    Mr. Honemond’s other proffers related to PTSD and Panic Disorder were too
    perfunctory and vague to be of value. Mr. Honemond just generally represented that
    he “has an array of different but worse complaints in 2020 than he had in 2017” and
    that “his condition[] has worsened.” There is no specificity in the descriptions of
    symptoms, and there are no supporting medical records to shed light on claimed
    symptoms or treatments. Cf. Walden v. D.C. Dep’t of Emp. Servs., 
    759 A.2d 186
    ,
    191 (D.C. 2000) (concluding that claimant met the threshold test when she offered
    a medical report from her doctor “clearly identif[ying] at least one new symptom
    attributable to . . . previous injury” and a “significant change in the degree of her
    disability”). These conclusory proffers are not enough.7
    7
    We also find no merit to Mr. Honemond’s contention that the ALJ
    incorrectly used a “preponderance of the evidence” standard for this claim. Instead,
    the ALJ properly examined whether Mr. Honemond had demonstrated a “reason to
    believe” that a change had occurred by comparing both the factual determinations in
    the previous compensation order on remand and the new evidence and proffers.
    18
    Mr. Honemond argues that the CRB erred as a matter of law by determining
    that a “worsening” condition would never merit modification.            The statute
    contemplates “worsening” conditions, as well as new conditions. See 
    D.C. Code § 32-1524
    (a)(1) (a claimant may apply for modification if there is a change regarding
    “the fact or the degree of disability”) (emphasis added). But a claimant must still
    show some reason to believe a change has occurred. For example, in Short, 
    723 A.2d at 848
    , in support of modification, Mr. Short presented new medical evidence
    from two different doctors, which showed that he was exhibiting new symptoms and
    had been diagnosed with a new disability attributable to a work injury. Similarly, in
    Young, 
    770 A.2d at 969
    , the initial compensation orders had acknowledged that Mr.
    Young had “some initial work-related disability.”       Mr. Young presented new
    testimony from his treating psychiatrist, as well as evidence of specific new
    symptoms, to show the “subsequent emergence of a work-related injury.” 
    Id. at 967, 970
    . In both cases, though there was some similarity between both the previously
    litigated conditions and the new conditions, the claimant provided adequate evidence
    of a “change” such that the modification provision would apply. Short, 
    723 A.2d at 850
    ; Young, 
    770 A.2d at 970
    .
    19
    Here, however, Mr. Honemond is not arguing that a recognized condition
    “worsened.” He is simply re-litigating the findings and conclusions from the first
    compensation order on remand. We previously affirmed that Mr. Honemond “did
    not suffer from a disabling mental injury that was causally related to his
    employment.”     Mr. Honemond cannot now claim that these conditions have
    “worsened” when he failed to establish that he had PTSD or panic disorder causally
    related to the work incident in the first place. Mr. Honemond is barred by collateral
    estoppel, to the extent he attempts to re-litigate the findings from the first
    compensation order on remand, and res judicata, to the extent that he re-litigates the
    same mental condition claims against intervenors. See Walden, 
    759 A.2d at 189
    .
    Mr. Honemond’s burden was to show that these doctrines do not apply, which he
    did not do.
    Overall, although a claimant has a minimal burden at the threshold stage, he
    must still present some evidence to suggest a “change of conditions” has occurred.
    Mr. Honemond has not. Accordingly, we affirm the judgment of the CRB.

    B.    Permanent Partial Disability
    Mr. Honemond also challenges the CRB’s determination that he is not entitled
    to permanent partial disability benefits because he did not demonstrate that he is
    permanently and partially disabled. We disagree and affirm.
    A claimant has the burden of proving, by the preponderance of the evidence,
    that he is entitled to a disability award. Washington Metro. Area Transit Auth. v.
    D.C. Dep’t of Emp. Servs., 
    926 A.2d 140
    , 149 (D.C. 2007) (“Browne”). A
    “disability” is a “physical or mental incapacity because of injury which results in the
    loss of wages.” Negussie v. D.C. Dep’t of Emp. Servs., 
    915 A.2d 391
    , 396 (D.C.
    2007) (quoting 
    D.C. Code § 32-1501
    (8)) (cleaned up). “An award may be paid for
    permanent partial disability, in which case ‘[c]ompensation for permanent partial
    loss or loss of use of a member may be for proportionate loss or loss of use of the
    member.’”

    “Disability is an economic and not a medical concept.” Washington Post v.
    D.C. Dep’t of Emp. Servs., 
    675 A.2d 37
    , 40 (D.C. 1996). “Disability, as defined in
    our statute, ultimately requires a legal determination.” Negussie, 
    915 A.2d at 397
    .
    A claimant is not entitled to any presumptions on the nature and extent of disability.

    Browne, 926 A.2d at 149. In determining disability, the most recent edition of the
    American Medical Association’s Guides to the Evaluation of Permanent Impairment
    may be utilized, along with factors of pain, weakness, atrophy, loss of endurance,
    and loss of function. Negussie, 
    915 A.2d at
    396 n.2 (citing 
    D.C. Code § 32-1508
    (U-i)). An “ALJ is required by statute to consider all the evidence and to exercise
    independent judgment in determining whether the claimant has a permanent
    disability and, if so, the extent of that disability.” Golding-Alleyne v. D.C. Dep’t of
    Emp. Servs., 
    980 A.2d 1209
    , 1215 (D.C. 2009).
    “The trier of fact is entitled to draw reasonable inferences from the evidence
    presented.” George Hyman Const. Co. v. D.C. Dep’t of Emp. Servs., 
    498 A.2d 563
    ,
    566 (D.C. 1985). The ALJ’s credibility determinations are entitled to great weight.
    Golding-Alleyne, 
    980 A.2d at 1213
    .             Our role in reviewing a credibility
    determination is to see whether it is supported by substantial evidence on
    consideration of the entire record. 
    Id. at 1214
    .
    The only disputed issue is the nature and extent of Mr. Honemond’s alleged
    physical disability. The medical evaluations provided competing opinions: Dr.
    Fechter opined that Mr. Honemond was 19% impaired, and Dr. Danziger opined that
    22
    Mr. Honemond was 0% impaired. 8 Mr. Honemond raises various challenges to the
    ALJ’s determination that Dr. Fechter’s report was unreliable and that he did not
    provide evidence of physical disability. We disagree.
    Substantial evidence supports the determination that Dr. Fechter’s report was
    unreliable and that Dr. Danziger’s report was reliable. The ALJ gave ample
    justification for not crediting Dr. Fechter’s report. The ALJ explained that Dr.
    Fechter’s report was unduly influenced by Mr. Honemond’s subjective complaints,
    which were not credible, as they were often contrary to the observations of treating
    medical personnel.    The ALJ also explained that Dr. Fechter’s report lacked
    meaningful explanation. Dr. Fechter reported that he generally observed “some
    weakness of grip strength” and atrophy in Mr. Honemond’s left arm. Dr. Fechter
    then determined, without explanation for the calculation of this number, that Mr.
    Honemond’s complaints of “weakness” supported an impairment rating of 10%. Dr.
    Fechter then allocated 2% for each “subjective factor[]” of pain, loss of endurance,
    and loss of function, with no further explanation.
    8
    There is a preference for the testimony of treating physicians over doctors
    retained for litigation purposes. Short, 
    723 A.2d at 851
    . Here, neither physician is
    Mr. Honemond’s treating physician.
    23
    The ALJ additionally determined that the basic math errors in Dr. Fechter’s
    report showed inattentiveness and obscured the basis for the impairment rating. Dr.
    Fechter erroneously totaled the impairment rating to 19% instead of 16%, which we
    agree both shows carelessness and also obscures the specifics and the total of the
    rating. It is unclear if Dr. Fechter meant to score Mr. Honemond as 16% impaired
    or if the individual components of the rating are not as reported.    The ALJ thus
    reasonably concluded that these factors weigh against the report’s credibility.
    The ALJ then reasonably credited Dr. Danziger’s report as persuasive. The
    ALJ explained that Dr. Danziger’s report had “objective findings” and that “his
    examination was performed with greater care.” Indeed, Dr. Danziger’s report
    includes notations on bending and rotation, range of motion, sensitivity, and skin
    turgor in Mr. Honemond’s arm.         Dr. Danziger explained that he based his
    impairment rating on the fact that Mr. Honemond has normal motor and sensory
    function, a full range of motion, normal skin and sensory changes, and no
    abnormality. Dr. Danziger further explained that he also reviewed Mr. Honemond’s
    medical records from the date of injury and subsequent treatment, which he took into
    account for his rating.
    24
    The ALJ thus gave ample and reasonable justification for crediting Dr.
    Danziger’s report, and discrediting Dr. Fechter’s report, and the CRB did not err in
    affirming the ALJ’s findings and conclusions. 9 Mr. Honemond failed to meet his
    burden in showing that he is entitled to an award for physical disability.
    Mr. Honemond also argues that there is not enough specificity in the order to
    support a determination that Mr. Honemond was not credible. We disagree.
    In judging Mr. Honemond’s credibility, the ALJ made specific comparisons
    between Mr. Honemond’s testimony and reports from treating nurses and physicians
    around the time of injury. While Mr. Honemond testified that he has diminished
    grip strength, Ms. Allely, his occupational therapist, reported that his grip strength
    was “well within functional norms” and that he “does not appear to have physical
    limitations[.]” Ms. Allely reported that there is “no wound, no discoloration, skin
    fully intact,” with “no reported discomfort or sensitivity.” As of August 2016, Ms.
    Allely concluded that Mr. Honemond had no more physical limitations.
    9
    The ALJ is not required to “choose a disability percentage rating provided
    either by the claimant’s or the employer’s medical examiner.” Negussie, 
    915 A.2d at 399
    . But the ALJ may choose to credit one medical report over another and adopt
    the impairment rating within. See Abebe v. D.C. Dep’t of Emp. Servs., 
    185 A.3d 723
    , 727 (D.C. 2018).
    25
    The ALJ also emphasized that Mr. Honemond was “fully treated” during the
    initial round of diagnosis and treatment in the summer of 2016. As Mr. Honemond
    testified, he did not seek out medical care for his arm after August 2016. While
    evidence of continuing medical care is not required to prove the existence of a
    disabling condition, “the nature and regularity of continuing medical care after the
    injury has stabilized may be useful information in assessing the statutory factors of
    pain, weakness, atrophy, loss of endurance, and loss of function[.]” Dent v. D.C.
    Dep’t of Emp. Servs., 
    158 A.3d 886
    , 904 (D.C. 2017), as amended (May 25, 2017).
    “[A] dearth of evidence of medical analysis and treatment is significant when
    assessing whether a claimant is entitled to a schedule award.” 
    Id.
     (internal quotations
    removed).
    The ALJ also heard Mr. Honemond’s testimony at the hearing and still did not
    credit it. See Washington Metro. Area Transit Auth. v. D.C. Dep’t of Emp. Servs.,
    
    683 A.2d 470
    , 477 (D.C. 1996) (“[T]he hearing examiner is in the best position to
    observe the demeanor of witnesses.”) (internal quotation marks and citations
    omitted). Overall, there was substantial evidence to support the ALJ’s determination
    that Mr. Honemond was not credible.10
    10
    We also find no merit to Mr. Honemond’s argument that the CRB “refus[ed]
    to evaluate” the ALJ’s credibility findings. The CRB explained that, on remand for
    26
    Finally, Mr. Honemond argues that the ALJ was required to arrive at an
    independent impairment percentage. An ALJ need not accept the impairment
    percentage of a medical expert; instead, an ALJ must exercise independent judgment
    in fixing a disability percentage rating. See Abebe v. D.C. Dep’t of Emp. Servs., 
    185 A.3d 723
    , 727 (D.C. 2018). In Abebe, this court explained that because the petitioner
    there had proved, by a preponderance of the evidence, that he had a disability, the
    ALJ was required to assign a percentage—the ALJ’s rejection of the competing
    medical evaluations and the percentages within them notwithstanding. 
    Id.
    Here, however, the ALJ credited Dr. Danziger’s report as “persuasive” and
    “reliable.” The ALJ further noted that “the record does not support a persuasive
    reason . . . to deviate from the zero-percent baseline Dr. Danziger identified.” The
    contrast to Abebe is clear: Mr. Honemond did not prove by a preponderance of the
    evidence that he has a disability, so the ALJ was not required to assign its own
    independent impairment percentage.
    this specific purpose, the ALJ made sufficient findings of fact to support its
    determination that Dr. Fechter’s opinions were unreliable.
    27
    III.   Conclusion
    For the foregoing reasons, we affirm the judgment of the CRB.                  Mr.
    Honemond did not show a “reason to believe” that a change of conditions had
    occurred such that he was entitled to an evidentiary hearing on his modification
    claim, and he also failed to prove that he is entitled to any disability benefits for his
    left arm.
    So ordered.
