    Asserting her rights under the Employee Retirement Income Security Act
    (ERISA) of 1974, 29 U.S.C. §§ 1001–1461, plaintiff Mary D. (M.D.) seeks recovery
    of residential-treatment benefits for her son, A.D., from Credit Suisse Securities
    (USA) LLC Group Health Care Plan (the Plan). The district court reviewed the Plan’s
    denial of benefits under an arbitrary-and-capricious standard and granted summary
    judgment in favor of the Plan and its claims administrator, Anthem UM Services, a
    *
    This order and judgment isn’t binding precedent, except under the doctrines
    of law of the case, res judicata, and collateral estoppel. But it may be cited for its
    persuasive value. Fed. R. App. P. 32.1; 10th Cir. R. 32.1.
    subsidiary fully owned by Anthem Blue Cross and Blue Shield (collectively,
    Anthem). For the reasons discussed below, we affirm.
    Background
    Because this case involves the denial of healthcare benefits—specifically, the
    denial of coverage for residential treatment of A.D.’s psychiatric disorder—we begin
    by explaining the terms of the Plan and some of A.D.’s medical history. Further,
    because this case comes to us after several levels of administrative review and
    because the standard of review is at issue, we also detail what occurred during the
    administrative review process and before the district court.
    I.    The Plan
    When the events relevant to this appeal transpired, M.D. worked for Credit
    Suisse Securities. Credit Suisse sponsored the Plan, which is a self-funded employee
    welfare benefits plan. M.D. elected to participate in the Plan and named her
    dependent son, A.D., as a beneficiary.
    The Credit Suisse Benefits Committee (the Benefits Committee) has “sole and
    complete discretionary authority” to administer the Plan. App. vol. 2C, 1264
    (sealed).1 But it delegated part of that authority to Anthem. As a result, Anthem has
    certain administrative responsibilities under the Plan: it determines who is eligible to
    1
    Via our September 14, 2018 and October 30, 2018 orders, we provisionally
    granted M.D.’s September 11, 2018 motion to seal volumes 2 through 2K of the
    appendix. To the extent we quote from these sealed volumes, we have determined the
    quoted material either appears in the parties’ briefs, which the parties did not file
    under seal, or isn’t sensitive. Cf. Fed. R. Civ. P. 5.2(h) (stating party waives privacy
    protection for own information by filing not under seal).
    2
    participate in the Plan, decides whether an individual will receive benefits, and
    interprets the terms of the Plan. Nevertheless, the Benefits Committee has the
    “ultimate responsibility” of administering the Plan. App. vol. 2B, 1056 (sealed).
    As relevant here, the Plan covers certain treatments for psychiatric disorders.
    But to be covered, any treatment—including treatment for such psychiatric
    disorders—must be medically necessary. And the Plan provides distinct
    medical-necessity criteria for different levels of psychiatric care.2 One category of
    medical-necessity criteria considers the severity of the relevant illness, evaluating the
    “condition and circumstances” of the individual seeking coverage. App. vol. 2, 461
    (sealed). And the severity-of-illness criteria for residential treatment requires the
    individual seeking coverage to demonstrate, among other things, the following:
    1. The [individual] is manifesting symptoms and behaviors [that]
    represent a deterioration from [his or her] usual status and include
    either self[-]injurious or risk[-]taking behaviors that risk serious
    harm and cannot be managed outside of a 24[-]hour structured
    setting or other appropriate outpatient setting; AND
    2. The social environment is characterized by temporary stressors or
    limitations that would undermine treatment that could potentially be
    improved with treatment while the [individual] is in the residential
    facility; AND
    3. There should be a reasonable expectation that the illness,
    condition[,] or level of functioning will be stabilized and improved
    2
    The two levels of care relevant to the issues on appeal are residential
    treatment and acute inpatient treatment. Residential treatment is “specialized
    treatment that occurs in a residential[-]treatment center. Residential treatment is 24
    hours per day and requires a minimum of one physician visit per week in a facility[-]
    based setting.” App. vol. 2, 467 (sealed). Acute inpatient treatment, on the other
    hand, is “treatment in a hospital psychiatric unit that includes 24-hour nursing and
    daily active treatment under the direction of a psychiatrist.” 
    Id. (sealed). 3
               and that a short[-]term subacute residential[-]treatment service will
    have a likely benefit on the behaviors/symptoms that required this
    level of care, and that the [individual] will be able to return to
    outpatient treatment.
    
    Id. at 463
    (sealed).
    The Plan also recommends that before receiving any particular treatment, the
    individual should request a pretreatment review from Anthem to “make sure the
    charges are medically necessary.” App. vol. 2C, 1324 (sealed). But the Plan doesn’t
    penalize the individual for failing to request pretreatment review. Indeed, the Plan
    expressly allows the individual to seek medical-necessity review after treatment.
    Nevertheless, the Plan cautions that if the individual seeks a retrospective review, he
    or she “run[s] the risk of reduced or denied benefits if the claims administrator finds
    that the care” received “is not medically necessary.” 
    Id. (sealed). If
    the individual
    disagrees with such a finding, the Plan provides level-one and level-two appeals.
    Anthem conducts level-one appeals. The Benefits Committee conducts level-two
    appeals.
    II.    A.D.’s Medical History and Treatment
    A.D. was first diagnosed with generalized anxiety disorder at age nine. His
    anxiety manifested in various ways: procrastination, perfectionism, rigidity,
    academic difficulty, and isolationism. In elementary school, he received outpatient
    treatment from a psychologist.
    A.D.’s anxiety escalated over time. In 2013, during his freshman year of high
    school, A.D. threatened to harm himself with a knife. As a result, he received two
    4
    weeks of inpatient treatment at a hospital, nearly two weeks of outpatient treatment,
    and then some additional inpatient treatment. After the second round of inpatient
    treatment, the hospital suggested A.D. be placed in residential treatment. Despite this
    recommendation, and with guidance from an education consultant, M.D. enrolled
    A.D. in a wilderness-therapy program called Aspiro.3
    A.D. stayed at Aspiro for nine and a half weeks. During that time, psychologist
    Todd Corelli observed that A.D. had difficulty dealing with his emotions and lacked
    useful coping skills. Corelli reported that A.D. was often angry, particularly toward
    his parents. Corelli’s observations aligned with A.D.’s father’s statement to Corelli
    that it was hard to manage A.D. at home. Corelli also noted that although A.D. had
    experienced suicidal thoughts in the past, A.D. reported he hadn’t been suicidal in
    three to four months.
    At the end of A.D.’s treatment at Aspiro, Corelli reported that A.D. had
    benefited from the program. But he recommended sending A.D. to a residential-
    treatment program, which could provide therapy and support 24 hours a day, so that
    A.D. could further internalize the improvements he’d made. A.D.’s therapist at
    Aspiro, Jamie Kaczmarek, echoed Corelli’s recommendation for residential
    treatment. She suggested that without the structure and support of a residential-
    treatment program, A.D.’s prior difficulties might resurface. Following these
    recommendations, M.D. sent A.D. to a residential-treatment center called Daniels
    3
    The Plan’s terms specify that “[w]ilderness programs” like Aspiro “are not
    considered residential[-]treatment programs.” App. vol. 2, 467 (sealed).
    5
    Academy. She later moved A.D. from Daniels Academy to another residential-
    treatment center called WayPoint Academy (WayPoint).
    WayPoint admitted A.D. based on A.D.’s anxiety disorder and its disruption to
    his daily life. At intake, WayPoint therapist Brett Walker conducted a suicide-risk
    screening. He noted that despite previous suicidal ideation, A.D. wasn’t currently
    suicidal and hadn’t been suicidal for several months. A.D. denied being suicidal at
    least twice more while at WayPoint. He remained at WayPoint for ten months.
    III.   Administrative Review Process
    A.    Initial Denial and Level-One Appeal
    M.D. didn’t request a pretreatment review for medical necessity before
    WayPoint admitted A.D. for treatment; Anthem first processed a claim for benefits
    after A.D. had been at WayPoint for several months. Anthem issued an Explanation
    of Benefits denying benefits because “EITHER NO PRECERT[IFICATION] WAS
    OBTAINED OR ADDITIONAL INFORMATION HAS BEEN REQUESTED.” App.
    vol. 2, 318 (sealed).
    In response, M.D. invoked the administrative review process, submitting a
    request for either a retrospective benefits determination or a level-one appeal. Along
    with the request, M.D. submitted invoices from WayPoint and A.D.’s medical
    records to allow Anthem to “conduct a retrospective review of all of his claims.” 
    Id. at 315
    (sealed). M.D. also asked Anthem to provide her with “specific detailed
    reasons for [any further] denial.” 
    Id. at 316
    (sealed).
    6
    As requested, Anthem conducted a retrospective review, which included a
    review by psychiatrist Narsimha Muddasani. Muddasani noted that after numerous
    failed attempts to contact WayPoint, he completed his medical-necessity review
    based on clinical notes in A.D.’s medical records. He found that A.D. had anxiety
    and poor family interaction; didn’t appear actively homicidal or suicidal; wasn’t
    psychotic or medically unstable; wasn’t placed on strict suicide watch; and could
    have been effectively treated in a lower level of care. Ultimately, after applying the
    medical-necessity criteria for residential treatment, Muddasani concluded that such
    treatment wasn’t medically necessary.
    Based on Muddasani’s review, Anthem denied benefits. Anthem issued an
    initial denial letter, stating in relevant part:
    The information your provider gave us does not show that [residential
    treatment] is medically necessary. You have not caused serious harm to
    anyone. You have not harmed yourself to such a degree that has caused
    serious medical problems. You have not had recent treatment for this in
    a structured outpatient program. You are also likely to benefit from
    structured outpatient treatment. We based this decision on the
    health[-]plan guidelines (Psychiatric Disorder Treatment—Residential
    Treatment Center (RTC) (CG-BEH-03)[)].
    App. vol. 2K, 3502 (sealed). Anthem stated M.D. could “request, free of charge,
    reasonable access to, and copies of all documents, records, and other information,
    including the . . . medical[-]necessity criteria that were used in making this decision.”
    
    Id. at 3503
    (sealed).
    7
    M.D. then sought a level-one appeal.4 In her appeal letter, M.D. provided a
    detailed medical history for A.D. She further provided clinical documentation
    regarding his treatment history and the recommendations for residential treatment
    from Corelli and Kaczmarek. M.D. requested a “full, fair, and thorough” level-one
    review and an explanation from Anthem “regarding the amount of weight [it] gave
    the clinical evidence . . . when making [its] determinations.” App. vol. 2D, 1519
    (sealed).
    As part of the level-one appeal, Anthem had another psychiatrist, Rasik Lal,
    conduct an additional medical-necessity review. Lal reviewed M.D.’s letters,
    Muddasani’s findings, Rudo’s findings, the initial denial letter, and A.D.’s medical
    records. Lal found A.D. wasn’t actively suicidal or homicidal when admitted to
    WayPoint; didn’t behave in a combative or psychotic manner; didn’t require
    continuous monitoring; wasn’t dangerous to himself or others; and didn’t present
    physiological problems or instabilities requiring residential treatment. Thus, like
    Muddasani before him, Lal concluded that the residential treatment wasn’t medically
    necessary.
    4
    WayPoint also filed its own level-one appeal with Anthem. As part of that
    separate appeal, Anthem requested that psychiatrist Andrew Rudo review A.D.’s
    medical records and apply the medical-necessity criteria for residential treatment.
    Rudo determined A.D.’s residential treatment at WayPoint wasn’t medically
    necessary, so Anthem denied WayPoint’s appeal.
    Although the outcome of WayPoint’s separate appeal isn’t before us, we
    mention Rudo’s review because a later reviewer and the district court both relied in
    part on his assessment.
    8
    Relying on Lal’s review, Anthem denied M.D.’s level-one appeal. Anthem
    stated that in resolving the appeal, it considered all the information that it received in
    connection with both the retrospective review and this level-one appeal. It further
    stated:
    Your doctor wanted you to have residential[-]treatment[-]center care.
    The reason we were given for this was that you were at risk for serious
    harm without 24[-]hour care. We understand that you would like us to
    change our first decision. Now we have new information from the
    medical records and appeal letter from your mother. We still do not
    think this was medically necessary for you. We believe our first
    decision was correct for the following reason: You were not at risk for
    serious harm [such] that you needed 24[-]hour care. You could have
    been treated with outpatient services. We based this decision on this
    health[-]plan guideline. (Psychiatric Disorder Treatment—Residential
    Treatment Center (RTC) (CG-BEH-03)).
    
    Id. at 1507
    (sealed). Anthem also offered, upon request, “copies of all documents[,]
    including the actual benefit provision, guideline, protocol, or other similar criterion
    on which this decision was based.” 
    Id. at 1509
    (sealed).
    B.    Level-Two Appeal
    After Anthem denied her level-one appeal, M.D. pursued a level-two appeal
    before the Benefits Committee. In her appeal letter, M.D. lodged a number of
    objections to Anthem’s retrospective review and level-one appeal. M.D. first pointed
    out that despite her request, Anthem didn’t specify the weight it gave to the treating
    physicians’ opinions or the medical records. She further suggested that Anthem and
    its reviewers hadn’t reviewed A.D.’s medical records at all. And she identified
    information in those medical records that, according to her, demonstrated that
    treatment at WayPoint was indeed medically necessary under the Plan’s residential-
    9
    treatment criteria. M.D. next complained that the initial denial letter and level-one
    appeal denial letter only stated “conclusions” and didn’t make “any specific
    references to the medical records.” 
    Id. at 1497
    (sealed). She requested that the
    Benefits Committee base its review on the residential-treatment criteria. M.D. also
    argued that Anthem’s reviewers had denial rates that “demonstrate[d] a lack of
    consideration for what is best for the member.” 
    Id. (sealed). In
    support, she pointed
    to a transcript from a news story that alleged Anthem’s reviewers had denial rates
    from 95 to 100 percent. M.D. asked the Benefits Committee to “tell [her] the denial
    rates of the last three years for [Lal] as well as [Muddasani].” 
    Id. (sealed). As
    part of the level-two appeal, the Benefits Committee requested that a
    physician from the Medical Review Institute of America (MRIoA) analyze whether
    A.D.’s treatment at WayPoint was medically necessary. The MRIoA physician
    reviewed the level-two appeal procedures, the residential-treatment criteria,
    WayPoint’s claims, M.D.’s letters, A.D.’s medical records, the prior medical
    reviewers’ determinations, and Anthem’s letters. The MRIoA physician initially
    addressed whether, “[p]er [the American Medical Association] or another
    professional standard of care,” A.D.’s “inpatient confinement in a [residential-
    treatment center was] supported by” his diagnosis or condition. App. vol. 2K, 3525
    (sealed). In answering that question, the MRIoA physician found there was no
    evidence that A.D. presented an imminent risk of harm to himself or others; he
    demonstrated no psychotic symptoms; and he exhibited no evidence of deteriorating
    function. As such, the MRIoA physician determined that “the available
    10
    documentation [did] not support a severity of symptoms that would require
    residential treatment.” 
    Id. at 3526
    (sealed).
    The MRIoA physician next addressed whether, “[b]ased on medical records,
    . . . the patient was at risk for serious harm that constituted [a need for] 24[-]hour
    care.” 
    Id. (sealed). As
    to that question, the MRIoA physician, consistent with Lal and
    Muddasani, found that A.D. didn’t demonstrate a risk of harm to himself or others
    that warranted 24-hour care. Thus, the MRIoA physician concluded that A.D.’s
    clinical presentation didn’t indicate that residential treatment was medically
    necessary.
    Relying on the MRIoA physician’s report, the information M.D. submitted
    with her appeal letter, the medical records that WayPoint submitted to Anthem, and
    “the relevant [P]lan provisions,” the Benefits Committee denied M.D.’s level-two
    appeal. 
    Id. at 3561
    (sealed). The Benefits Committee stated that its “determination
    was in agreement with Anthem’s view that [A.D.’s] clinical presentation did not
    support the use of residential-treatment care during” his time at WayPoint. 
    Id. (sealed). The
    Benefits Committee also informed M.D. that she had “the right to
    receive, upon request and without charge, reasonable access to or copies of any
    relevant documents, records, or other information relied upon” in the level-two
    appeal. 
    Id. (sealed). IV.
       District-Court Proceedings
    After exhausting the administrative review process, M.D. filed this lawsuit in
    district court seeking recovery of benefits. See § 1132(a)(1)(B). The parties filed
    11
    cross-motions for summary judgment. In ruling on these cross-motions, the district
    court first determined that because the Plan gave Anthem and the Benefits Committee
    discretionary authority and because “there were no procedural deficiencies . . . that
    r[o]se to the level of lessening the standard of review,” the arbitrary-and-capricious
    standard of review applied. App. vol. 1, 223. Second, the district court determined
    that the opinions of the four reviewing physicians supported the denial of benefits
    and that the denial wasn’t arbitrary and capricious. Thus, the district court denied
    M.D.’s motion for summary judgment and granted summary judgment to Anthem and
    the Plan. M.D. now appeals.
    Analysis
    M.D. asserts the district court erred by applying the wrong standard of review
    when it assessed Anthem and the Plan’s decision to deny benefits. Specifically, M.D.
    alleges that rather than deferring to Anthem and the Plan’s decision by asking
    whether it was arbitrary and capricious, the district court should have reviewed
    Anthem and the Plan’s decision de novo.
    For the reasons discussed below, we reject this argument and hold that the
    district court did not err in reviewing Anthem and the Plan’s decision under the
    deferential arbitrary-and-capricious standard. See infra Section I. And we further
    conclude that even assuming the district court did err in applying this more
    deferential standard of review, that error was harmless; Anthem and the Plan’s
    decision to deny benefits survives even de novo review. See infra Section II.
    12
    I.    The Applicable Standard of Review
    M.D. contends that the district court erred in applying a deferential standard of
    review to Anthem and the Plan’s decision to deny benefits. “We review de novo the
    ‘district court’s determination of the proper standard to apply in its review of an
    ERISA plan administrator’s decision . . . .’” Rasenack ex rel. Tribolet v. AIG Life Ins.
    Co., 
    585 F.3d 1311
    , 1315 (10th Cir. 2009) (alteration in original) (quoting DeGrado
    v. Jefferson Pilot Fin. Ins. Co., 
    451 F.3d 1161
    , 1167 (10th Cir. 2006)).
    A district court applies de novo review in a benefits-eligibility case “unless the
    benefit plan gives the administrator or fiduciary discretionary authority to determine
    eligibility for benefits or to construe the terms of the plan.” Firestone Tire & Rubber
    Co. v. Bruch, 
    489 U.S. 101
    , 115 (1989) (emphasis added). Where the plan gives the
    fiduciary or administrator discretionary authority, the district court “employ[s] a
    deferential standard of review, asking only whether the denial of benefits was
    arbitrary and capricious.” Eugene S. v. Horizon Blue Cross Blue Shield of N.J., 
    663 F.3d 1124
    , 1130 (10th Cir. 2011) (quoting LaAsmar v. Phelps Dodge Corp. Life,
    Accidental Death & Dismemberment & Dependent Life Ins. Plan, 
    605 F.3d 789
    , 796
    (10th Cir. 2010)). But even where the plan affords such discretionary authority to the
    fiduciary or administrator, deferential review isn’t guaranteed: in the face of
    procedural irregularities in the administrative review process, a district court will
    instead review the benefits denial de novo. See 
    LaAsmar, 605 F.3d at 797
    ; Gilbertson
    v. Allied Signal, Inc., 
    328 F.3d 625
    , 631 (10th Cir. 2003).
    13
    In this case, M.D. concedes that the Plan’s terms give the Benefits Committee
    and Anthem complete discretion to administer it. Thus, the district court would have
    ordinarily reviewed Anthem and the Benefits Committee’s decision for arbitrariness.
    
    Firestone, 489 U.S. at 115
    . Nevertheless, M.D. argues that four procedural
    irregularities in the administrative review process should have triggered de novo
    review. Specifically, she asserts that (1) Anthem shifted its basis for denying the
    claim; (2) Anthem and the Benefits Committee failed to engage in a meaningful
    dialogue with her; (3) the Benefits Committee failed to respond to her request for
    specific information; and (4) Anthem and the Benefits Committee used the incorrect
    medical-necessity criteria. We address each assertion in turn.
    First, M.D. alleges that Anthem based its denial on “shifting” and
    “inconsistent” reasons. Aplt. Br. 34. In support, she points out that Anthem initially
    indicated in the Explanation of Benefits (EOB) that it denied coverage either because
    M.D. failed to obtain precertification or because Anthem had requested but hadn’t yet
    received certain additional information. Yet Anthem’s later denials, M.D. points out,
    turned on the lack of medical necessity.
    But M.D. doesn’t explain how these two responses are inconsistent. Critically,
    the denial in the EOB didn’t turn solely on the absence of precertification;5 instead, it
    pointed out that in the absence of precertification, Anthem needed additional
    5
    Indeed, precertification couldn’t be the sole basis for the denial in the EOB;
    the Plan’s terms specifically state that there is no penalty for failing to obtain
    precertification.
    14
    information to process the claim. That is, the EOB simply sought additional
    information that would allow Anthem to conduct a retrospective review of whether
    the treatment was medically necessary and therefore covered under the Plan’s terms.
    Once Anthem conducted that retrospective review using the additional information
    that M.D. provided—as M.D. specifically asked it to do—it concluded that
    residential treatment wasn’t medically necessary. And after that review, Anthem
    consistently denied benefits based on medical necessity. Accordingly, Anthem’s
    reasons for denying coverage didn’t shift over time, and we reject M.D.’s first
    procedural-irregularity argument.
    M.D. next argues that Anthem and the Benefits Committee failed to engage in
    a “meaningful dialogue” with her during the administrative process. Aplt. Br. 38. The
    meaningful-dialogue requirement stems from subsections (g) and (h) of 29 C.F.R.
    § 2560.503-1.6 See Metzger v. UNUM Life Ins. Co. of Am., 
    476 F.3d 1161
    , 1168 n.4
    (10th Cir. 2007) (stating that requirements in § 2560.503-1(g) and (h) “enable
    claimants to submit informed responses to the adverse decision and to engage in
    meaningful dialogue with the plan administrator”); 
    Gilbertson, 328 F.3d at 635
    (stating that ERISA and its regulations contemplate “meaningful dialogue” between
    plan administrators and claimants (quoting Booton v. Lockheed Med. Benefit Plan,
    6
    Technically, subsection (g) applies only to notifications of benefits and
    subsection (h) applies only to appeal denials. See Hancock v. Metro. Life Ins. Co.,
    
    590 F.3d 1141
    , 1153 (10th Cir. 2009). But in this case, the Plan’s terms make most of
    the provisions of subsection (g) applicable to notifications of benefits and appeal
    denials, rendering this technical distinction irrelevant.
    15
    
    110 F.3d 1461
    , 1463 (9th Cir. 1997))). Subsection (g), as incorporated by the Plan,
    requires in part that any notice of denial must (1) provide the specific reason for the
    adverse determination, (2) reference the specific provision warranting denial, and
    (3) for medical-necessity denials, explain the scientific or clinical judgment
    supporting the determination. Here, the initial denial letter, the level-one appeal
    denial letter, and the level-two appeal denial letter met these requirements: they cited
    lack of medical necessity as the specific reason for each denial; they referenced the
    residential-treatment criteria that governed the medical-necessity determination; and
    they provided clinical judgment supporting each denial. Thus, none of the letters
    violate the requirements of subsection (g).
    We next turn to subsection (h). That subsection requires every plan to provide
    claimants “a reasonable opportunity to appeal[,] . . . under which there will be a full
    and fair review of the claim and the adverse benefit determination.” § 2560.503-
    1(h)(1). Full and fair reviews must, among other things, “take[] into account all
    comments, documents, records, and other information submitted by the claimant
    relating to the claim,” and provide “reasonable access to, and copies of, all
    documents, records, and other information relevant to the claimant’s claim for
    benefits.” § 2560.503-1(h)(2)(iii), (iv). Additionally, in deciding an appeal based on
    medical necessity, the plan must “consult with a health[]care professional who has
    appropriate training and experience in the field of medicine involved in the medical
    judgment.” § 2560.503-1(h)(3)(iii).
    16
    Here, both the level-one and level-two appeal denial letters show that Anthem
    and the Benefits Committee provided a full and fair review. For instance, Anthem
    consulted Lal during the level-one appeal, and the Benefits Committee consulted an
    MRIoA physician during the level-two appeal. Anthem, the Benefits Committee, and
    the medical reviewers all stated they considered the letters and records that M.D.
    submitted. And although M.D. asserts that she requested responses to the materials
    and arguments she submitted, she doesn’t cite any authority—nor are we aware of
    any—that required Anthem and the Benefits Committee to affirmatively respond to
    these submissions. Instead, subsection (h) merely required Anthem and the Benefits
    Committee to “take[]” these materials and arguments “into account.”7 § 2560.503-
    1(h)(2)(iv). Moreover, Anthem and the Benefits Committee stated in both appeal
    denial letters that M.D. could have access to the records they relied on in making the
    benefits determination free of charge. As such, M.D. hasn’t demonstrated that
    Anthem or the Benefits Committee violated subsections (g) or (h) or failed to engage
    7
    M.D. cites to Gaither v. Aetna Life Insurance Co., 
    394 F.3d 792
    , 802 (10th
    Cir. 2004), for the proposition that the Tenth Circuit requires “more” than what she
    characterizes as a “reassuring pat[] on the head” that the plan administrator
    “considered all of the materials” she submitted. Aplt. Br. 39. But Gaither—a case
    involving the denial of long-term disability benefits, rather than the denial of medical
    benefits—is 
    inapposite. 394 F.3d at 795
    . Compare § 2560.503-1(g)(1)(v) (requiring
    denial of medical benefits to include “explanation of the scientific or clinical
    judgment for the determination”), with § 2560.503-1(g)(1)(vii) (requiring denial of
    disability benefits to include both “explanation of the scientific or clinical judgment
    for the determination” and basis for disagreeing with or not following “views
    presented by the claimant to the plan of health[]care professionals treating the
    claimant and vocational professionals who evaluated the claimant”).
    17
    in a meaningful dialogue at the notification-of-benefits or appeal stages. So we find
    no procedural irregularity on this basis.
    In a related procedural-irregularity argument, M.D. next asserts that the
    Benefits Committee failed to provide her with certain information during her level-
    two appeal—specifically, “the denial rates of the last three years” for Lal and
    Muddasani. App. vol. 2D, 1497 (sealed). In support, M.D. points out that the
    regulations entitle a claimant to “reasonable access to, and copies of, all documents,
    records, and other information relevant to the claimant’s claim for benefits.”
    § 2560.503-1(h)(2)(iii) (emphasis added). Information is relevant to a claim for
    benefits if it “[d]emonstrates [the administrator’s] compliance with the administrative
    processes and safeguards required pursuant to paragraph (b)(5).” § 2560.503-
    1(m)(8)(iii). And paragraph (b)(5), in turn, requires the administrator to put
    procedures in place to ensure both that “benefit claim determinations are made in
    accordance with governing plan documents” and that the plan is “applied consistently
    with respect to similarly situated claimants.” § 2560.503-1(b)(5).
    According to M.D., the denial rates are relevant to her claim for benefits
    because they could demonstrate whether Anthem complied with procedures that
    ensure the Plan is properly and consistently applied. To begin, she offers a
    conditional reason for why the denial rates may show Anthem didn’t properly apply
    the Plan’s terms: they “may” show high denial rates for the reviewers. Aplt. Br. 38.
    In making this argument, M.D. seems to be conflating the broad concept of relevance
    under the Federal Rules of Evidence with the narrow regulatory definition of
    18
    relevance in subsection (m)(8)(iii). But these are distinctly different standards of
    relevance. Compare Fed. R. Evid. 401 (stating that evidence is relevant if “it has any
    tendency to make a fact more or less probable than it would be without the
    evidence”), with § 2560.503-1(m)(8)(iii) (stating that information is relevant if it
    “[d]emonstrates [the administrator’s] compliance with the administrative processes
    and safeguards”). And M.D. provides no authority to support her assertion that the
    denial rates are relevant under the narrower regulatory provision merely because they
    might show Anthem’s lack of compliance with safeguards and procedures. Nor have
    we found any. The regulation states that relevant information is that which in fact
    demonstrates compliance, and M.D. fails to explain how the denial rates meet that
    standard. We therefore reject M.D.’s argument that the denial rates are relevant to
    show proper application of the Plan.
    Next, M.D. argues that if the denial rates for Lal and Muddasani are
    substantially different, the disparity may show inconsistent application of the Plan to
    similarly situated claimants. As an initial matter, this argument suffers from the same
    infirmity as M.D.’s prior point—it relies on an overbroad definition of relevance.
    Further, as Anthem and the Plan point out, Lal’s and Muddasani’s denial rates
    wouldn’t, standing alone, demonstrate that Anthem applied the Plan’s terms
    inconsistently to similarly situated claimants. That’s because the denial rates
    wouldn’t shed any light on whether the denied claimants were in fact similarly
    situated: for instance, denial rates wouldn’t show whether the denied claimants were
    the same age as A.D., whether they were diagnosed with generalized anxiety
    19
    disorder, or whether they were seeking coverage for residential treatment. Thus, we
    also reject M.D.’s assertion that the denial rates are relevant to show inconsistent
    application of the Plan among similarly situated claimants.
    In her fourth and final procedural-irregularity argument, M.D. alleges that the
    medical reviewers for Anthem and the Benefits Committee erroneously used the
    medical-necessity criteria for acute inpatient care rather than the criteria for
    residential treatment. For acute inpatient care—which is a higher degree of care than
    residential treatment—the criteria are more onerous. In particular, the acute-
    inpatient-care criteria require, among other things, “[i]mminent suicidal risk or
    danger to others.” App. vol. 2, 461 (sealed). But for residential treatment, the criteria
    require only “self[-]injurious or risk[-]taking behaviors that risk serious harm.” 
    Id. at 463
    (sealed).
    In support for her position that the reviewers relied on the former rather than
    the latter, M.D. points to the reviewers’ findings on A.D.’s risk for suicide and
    homicide, alleging that those findings mirror the criteria for acute inpatient care, not
    residential treatment.
    As an initial matter, we note that Lal, Muddasani, and Anthem all specified the
    residential-treatment criteria, not the acute-inpatient-care criteria, as the basis for
    their determination. What’s more, none of the reviewers even mentioned the acute-
    inpatient-care criteria. Neither did Anthem or the Benefits Committee. We see no
    reason to think these entities identified one set of criteria but applied another.
    Further, as the district court explained, the criteria for acute inpatient care and
    20
    residential treatment partially overlap. That is, although Lal, Muddasani, and the
    MRIoA reviewer implicitly addressed the acute-inpatient-care criteria by finding that
    A.D. wasn’t suicidal or at imminent risk of self-harm when WayPoint admitted him,
    these findings were also relevant to determining whether, for purposes of applying
    the residential-treatment criteria, he was engaging in self-injurious or risk-taking
    behavior that risked serious harm. For instance, a finding that A.D. had repeatedly
    attempted suicide would necessarily compel the conclusion that he was engaged in
    self-injurious behavior. Likewise, a finding that A.D. had recently attempted
    homicide would necessarily compel the conclusion that he was engaged in behavior
    that risked serious harm to others. Thus, the reviewers’ reliance on their findings
    about the existence or nonexistence of A.D.’s homicidal and suicidal ideations
    doesn’t indicate that they used the incorrect medical-necessity standard.
    Moreover, the issue of whether residential treatment is medically necessary
    turns on more than just risk of harm; it also requires a finding that the individual’s
    disorder can’t be properly “managed outside of a 24[-]hour structured setting or other
    appropriate outpatient setting.” App. vol. 2, 463 (sealed). And Lal, Muddasani, and
    the MRIoA physician found A.D. failed to meet this criterion because he didn’t need
    continuous monitoring and treatment. Likewise, Anthem mentioned A.D.’s failure to
    satisfy this criterion in the initial denial letter and in the level-one appeal denial
    letter. Notably, this consideration—whether the disorder can be managed in
    outpatient care—isn’t part of the acute-inpatient-care criteria. Thus, we reject M.D.’s
    21
    argument that Anthem and the Benefits Committee procedurally erred by applying
    the incorrect medical-necessity criteria.
    In short, M.D. fails to identify any procedural irregularities in the
    administrative review process.8 Accordingly, the district court did not err in applying
    the arbitrary-and-capricious standard of review.
    II.   Denial of Residential-Treatment Benefits
    Alternatively, even assuming we agreed with M.D. and concluded that the
    district court erred in applying the arbitrary-and-capricious standard of review, that
    conclusion wouldn’t necessarily entitle M.D. to relief. Instead, this conclusion would
    only permit us to reverse the district court’s decision outright if M.D. could show that
    the district court’s error prejudiced her—i.e., that it can be reasonably concluded the
    district court would have reversed the denial of benefits had it reviewed the denial
    decision de novo. See Fed. R. Civ. P. 61 (“At every stage of the proceeding, the court
    must disregard all errors and defects that do not affect any party’s substantial
    rights.”); Shinseki v. Sanders, 
    556 U.S. 396
    , 410 (2009) (noting that in civil cases,
    “the party seeking reversal normally must explain why the erroneous ruling caused
    8
    Because we find no procedural irregularities in the administrative review
    process, we need not address M.D.’s argument that the substantial-compliance
    doctrine no longer applies under the 2002 version of the ERISA procedural
    regulations. See 
    Gilbertson, 328 F.3d at 634
    –35 (defining substantial-compliance
    doctrine as court’s willingness to “overlook administrators’ failure to meet certain
    procedural requirements” when administrator “substantially complied with the
    regulations”); 
    Rasensack, 585 F.3d at 1316
    (“The 2002 amendments have . . . called
    into question the continuing validity of the substantial[-]compliance [doctrine]
    . . . .”).
    22
    harm”). For the reasons discussed below, we conclude that M.D. cannot make this
    showing here; even under de novo review, we see no indication that Anthem and the
    Plan wrongly denied benefits. Thus, even assuming the district court erred in failing
    to review Anthem and the Plan’s decision de novo, that error was harmless.
    In performing this prejudice analysis, we review Anthem and the Plan’s
    decision to deny benefits, “as opposed to reviewing the district court’s ruling.”

    578 F.3d 1187
    , 1192 (10th Cir. 2009). In so
    doing, “[o]ur review is ‘limited to the administrative record—the materials compiled
    by the administrator in the course of making [its] decision.’” 
    Id. (quoting Fought
    v.
    UNUM Life Ins. Co. of Am., 
    379 F.3d 997
    , 1003 (10th Cir. 2004)).
    As stated above, A.D.’s residential treatment was only covered if it was
    medically necessary. And under the Plan’s terms, residential treatment for a
    psychiatric disorder is only medically necessary if the individual meets three criteria.
    First, the individual must manifest deterioration from his or her usual status and
    demonstrate self-injurious or risk-taking behaviors that risk serious harm and cannot
    be managed outside of a 24-hour structured setting. We refer to these three
    requirements collectively as the injury-risk criterion and separately as the
    deterioration requirement, the behaviors requirement, and the 24-hour requirement.
    Second, the individual’s social environment must have temporary stressors or
    limitations that could undermine treatment (the social-environment criterion). Third,
    the individual must reasonably be expected to both stabilize and improve from short-
    term residential treatment and then return to outpatient treatment. We refer to these
    23
    two requirements collectively as the reasonable-expectation criterion and separately
    as the stabilization requirement and the return-to-outpatient-care requirement. M.D.
    argues that she can meet her burden to establish that A.D. met these criteria and that
    Anthem and the Plan therefore wrongly denied her claim for benefits. See 
    Rasenack, 585 F.3d at 1324
    .9
    1.     The Injury-Risk Criterion
    In attempting to show A.D. satisfied the behaviors requirement (i.e., that he
    displayed self-injurious or risk-taking behaviors that posed a risk of serious harm),
    M.D. relies exclusively on the opinions of treating medical providers Corelli and
    Kaczmarek. Corelli and Kaczmarek recommended that A.D. obtain residential
    treatment after he completed Aspiro’s wilderness-therapy program. But ERISA
    doesn’t require an administrator to defer to a treating physician’s opinion. See Black
    & Decker Disability Plan v. Nord, 
    538 U.S. 822
    , 825 (2003) (“We hold that [under
    ERISA,] plan administrators are not obliged to accord special deference to the
    opinions of treating physicians.”). Instead, ERISA merely prohibits administrators
    from “arbitrarily refus[ing] to credit . . . the opinions of a treating physician.” 
    Id. at 834.
    Thus, Anthem and the Benefits Committee weren’t required to defer to Corelli
    or Kaczmarek in the face of other credible medical evidence. And they possessed
    9
    M.D. also faults Anthem and the Benefits Committee for failing to discuss all
    three of these criteria. But the residential-treatment criteria are conjunctive. That is,
    the absence of any one criterion would preclude a finding of medical necessity. Thus,
    because Anthem and the Benefits Committee found that A.D. failed to satisfy the
    injury-risk criterion, they were not required to address the social-environment
    criterion or the reasonable-expectation criterion.
    24
    other credible evidence in this case, in the opinions from Lal, Muddasani, and the
    MRIoA reviewer. See Blair v. Alcatel-Lucent Long Term Disability Plan, 688 F.
    App’x 568, 576 (10th Cir. 2017) (unpublished) (finding plan administrator wasn’t
    required to defer to treating physician where credible evidence from file reviewer and
    primary-care physician supported denial of coverage).
    Undeterred, M.D. also argues that because A.D.’s condition involves mental
    health, “[i]t is especially improper to ignore the findings and conclusions of a
    patient’s treating physician.” Aplt. Br. 45. In support, she relies on numerous Sixth
    Circuit cases that question the reliability of file reviews in benefits disputes related to
    the treatment of psychiatric disorders. See, e.g., Okuno v. Reliance Standard Life Ins.
    Co., 
    836 F.3d 600
    , 611–12 (6th Cir. 2016) (“File reviews are particularly
    ‘questionable as a basis’ for an administrator’s determination to deny benefits where
    the claim, as here, involves a mental[-]illness component.” (quoting Javery v. Lucent
    Techs., Inc. Long Term Disability Plan for Mgmt. or LBA Emps., 
    741 F.3d 686
    , 702
    (6th Cir. 2014))); Smith v. Bayer Corp. Long Term Disability Plan, 275 F. App’x
    495, 505–09 (6th Cir. 2008) (unpublished) (“Courts discount the opinions of
    psychiatrists who have never seen the patient for obvious reasons.” (quoting Sheehan
    v. Metro. Life Ins. Co., 
    368 F. Supp. 2d 228
    , 255 (S.D.N.Y. 2005))). But we have
    uncovered no similar caselaw in our circuit, and M.D. points to none. In fact, we
    have expressly rejected the argument that administrators must defer to treating
    physicians in the mental-health context. See Eugene 
    S., 663 F.3d at 1134
    –35
    (rejecting appellant’s argument that opinion of treating physician is entitled to special
    25
    weight in ERISA benefits dispute related to mental-health treatment). Thus, we aren’t
    persuaded that we must depart from the general rule that we need not “accord special
    deference to the opinions of treating physicians.” 
    Nord, 538 U.S. at 825
    ; see also
    Eugene 
    S., 663 F.3d at 1135
    (declining plaintiff’s “invitation to announce a
    ‘treating[-]physician rule’ for ERISA claims relating to mental[-]health care”).
    Further, even if we were to credit the treating medical providers’ opinions,
    those opinions don’t necessarily contradict the conclusion that A.D. wasn’t engaging
    in self-injurious or risk-taking behaviors when WayPoint admitted him. At Aspiro,
    Corelli noted that although A.D. had suicidal thoughts in the past, A.D. hadn’t been
    suicidal in three or four months. Likewise, once A.D. entered WayPoint, Walker
    conducted a suicide-risk screening and determined that A.D. hadn’t thought of
    suicide in the previous few months and wasn’t currently suicidal or threatening self-
    harm. And A.D. denied being suicidal at least twice more while at WayPoint. The
    only real evidence of self-injurious or risk-taking behavior was A.D.’s suicide threat
    in February 2013—but that occurred approximately six months before he entered
    WayPoint. Further, and critically, although Corelli and Kaczmarek recommended
    residential treatment after Aspiro, they did so based on their belief that A.D. needed
    to internalize the improvements he made at Aspiro, not because he was engaged in
    self-injurious or risk-taking behavior. Accordingly, even assuming Anthem and the
    Benefits Committee should have deferred to the treating providers, we see no
    26
    indication that they would have reached a different medical-necessity conclusion had
    they done so.10
    Moreover, contrary to M.D.’s argument that residential treatment was
    medically necessary because A.D. was engaging in self-injurious and risk-taking
    behaviors, considerable credible evidence supports the opposite conclusion.
    Muddasani determined A.D. didn’t appear actively homicidal or suicidal; wasn’t
    psychotic or medically unstable; wasn’t on strict suicide watch; and could have been
    treated with a lower level of care. Lal found A.D. wasn’t actively suicidal or
    homicidal when WayPoint admitted him; didn’t behave in a combative or psychotic
    manner; didn’t require continuous monitoring; wasn’t dangerous to himself or others;
    and didn’t present physiological problems or instabilities requiring residential
    treatment care. And the MRIoA reviewer stated A.D. didn’t demonstrate a risk of
    harm to himself or others warranting 24-hour care. Also, each reviewer
    independently concluded A.D. could have been treated with a lower level of care. In
    turn, based on the reviewers’ findings, Anthem and the Benefits Committee
    concluded that A.D. wasn’t engaging in self-injurious or risk-taking behaviors. In
    10
    In M.D.’s appeal letters, she included additional excerpts from A.D.’s
    medical records that, according to M.D., support a finding that residential treatment
    was medically necessary. She doesn’t explicitly identify many of these excerpts in
    her briefing. But we have reviewed the excerpts in her appeal letters and find nothing
    that would indicate A.D. was displaying self-injurious or risk-taking behaviors that
    couldn’t be managed in an outpatient setting. And even assuming such evidence
    exists elsewhere in the record, “[n]othing in ERISA requires plan administrators”—or
    reviewing courts, for that matter—“to go fishing for evidence” that a claimant
    doesn’t “br[ing] to their attention.” 
    Rasenack, 585 F.3d at 1325
    (quoting 
    Gaither, 394 F.3d at 804
    ).
    27
    sum, then, regardless of whether we credit the treating physicians or the medical
    reviewers, M.D. hasn’t demonstrated that A.D. met this criterion when he entered
    WayPoint.
    Nor has M.D. shown that A.D. met the other part of this criterion—i.e., that he
    “manifest[ed] symptoms and behaviors [that] represent[ed] a deterioration from [his]
    usual status”—prior to entering WayPoint. App. vol. 2, 463 (sealed). On this
    deterioration requirement, M.D. urges us to consider A.D.’s condition not just at the
    time he entered WayPoint, but “from a more broad[-]spectrum perspective.” Reply
    Br. 22. M.D. doesn’t cite any authority for her broad-spectrum point. Nor have we
    found any. Moreover, the record simply doesn’t show that A.D.’s condition was
    deteriorating at the time he entered WayPoint or in the preceding months. Instead, the
    record shows that A.D. had been improving. Prior to attending WayPoint, A.D.
    attended Aspiro and Daniels Academy. Corelli found that A.D. significantly
    benefited from his time at Aspiro. Kaczmarek likewise noted A.D.’s improvements
    after Aspiro. Thus, although A.D.’s condition may have deteriorated before attending
    Aspiro, as M.D. posits, we cannot say that his condition deteriorated before he
    entered WayPoint.
    In sum, we find that the record presents no evidence that A.D. was
    deteriorating or engaging in self-injurious or risk-taking behavior that couldn’t be
    managed except in a 24-hour structured setting. He therefore fails to satisfy the
    injury-risk criterion. And because the three medical-necessity criteria for residential
    treatment are conjunctive, we reject M.D.’s argument that A.D.’s residential
    28
    treatment was medically necessary. But in the interest of completeness, we briefly
    address M.D.’s arguments on the remaining two criteria.
    2.     The Social-Environment Criterion
    M.D. next argues that “it is evident that [A.D.] was subjected to temporary
    stressors or limitations at home that made removal from that social environment
    necessary.” Aplt. Br. 55. Notably, she cites nothing in the record to support this
    assertion. And although our independent review of the record indicates this may have
    been true before A.D. attended Aspiro, we see no indication this was still the case by
    the time WayPoint admitted him. Instead, Corelli indicated that A.D. had benefited
    from Aspiro. Likewise, Kaczmarek noted that upon his discharge from Aspiro, A.D.
    had stabilized. And because A.D. never went home between leaving Aspiro and
    entering WayPoint, there’s simply no way to know whether his home would have
    been a temporary stressor or limitation that would have undermined his treatment.
    Under these circumstances, we conclude that M.D. has failed to demonstrate that
    when A.D. entered WayPoint, his family remained a “temporary stressor or
    limitation[]” that would undermine his treatment. App. vol. 2, 463 (sealed); see also
    
    Rasenack, 585 F.3d at 1324
    .
    3.     The Reasonable-Expectation Criterion
    In addressing this third criterion, M.D. points to an absence in the record of
    any finding that A.D. failed to satisfy this criterion, rather than to the presence of any
    29
    record evidence that might support a contrary finding.11 But the absence of such a
    finding isn’t relevant; it’s M.D.’s burden to show that A.D.’s residential treatment
    was medically necessary, not the administrator’s burden to show they determined it
    wasn’t. See 
    Rasenack, 585 F.3d at 1324
    . And M.D. fails to satisfy that burden here.
    Conclusion
    For the reasons outlined above, we conclude that the district court didn’t err
    when it reviewed the benefits denial for arbitrariness. Alternatively, even assuming
    the district court should have reviewed the denial decision de novo, we conclude that
    the district court’s error in failing to do so was harmless; the denial decision survives
    even de novo review because A.D.’s residential treatment wasn’t medically
    necessary.12 Accordingly, we affirm the district court’s order entering summary
    judgment in favor of Anthem and the Benefits Committee. As a final matter, we grant
    M.D.’s motion to seal.

    M.D. insists she “provided” such “evidence” to Anthem during the review
    process. Rep. Br. 23. But she neither identifies the specific evidence she provided nor
    directs our attention to the location in the record where that evidence appears. Cf.
    Fed. R. App. P. 28(a)(8)(A) (requiring appellant to provide “citations to . . . parts of
    the record” relied on).
    12
    Likewise, because M.D.’s wrongful-denial argument fails even under de
    novo review, we need not separately address whether, as she asserts, the decision to
    deny benefits was arbitrary and capricious. See Nance v. Sun Life Assurance Co. of
    Can.,
