  •                                UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    FIRSTHEALTH MOORE REGIONAL
    HOSPITAL,
    Plaintiff,                        Civil Action No. 20-1007 (BAH)
    v.                                Chief Judge Beryl A. Howell
    XAVIER BECERRA,
    Secretary of Health and Human Services,
    Defendant.
    MEMORANDUM OPINION
    Plaintiff FirstHealth Moore Regional Hospital made a deliberate and strategic decision to
    pursue review of a calculation for reimbursement of Medicare uncollectible patient debts by
    asking the U.S. Department of Health and Human Services (“HHS”) contractor administering the
    calculation process to revisit certain issues that plaintiff believed involved errors. This choice of
    review process avoided the higher-overhead and potentially more time-consuming process of
    formal agency review authorized by statute. Ultimately, however, when the contractor reviewed
    plaintiff’s objections, made adjustments to certain calculations, and declined to make
    adjustments to others, this choice of review pathway, effectuated by withdrawal of the initial
    appeal, foreclosed continuing with the formal appeals process before HHS’s Provider
    Reimbursement Review Board (“PRRB”) for the items the contractor reviewed but did not
    adjust.
    Plaintiff now seeks to force HHS to reinstate its formal appeal filed before the PRRB,
    arguing that the PRRB’s rules unlawfully deprived plaintiff of statutory appeal rights, first, by
    forcing withdrawal of its formal appeal to pursue the more informal review process with the
    1
    contractor and then, second, by refusing to allow reinstatement of plaintiff’s formal appeal after
    the informal contractor review failed to produce an entirely satisfactory modification of the
    reimbursement amount that plaintiff claims was erroneously calculated. HHS disputes plaintiff’s
    first assertion and denies that agency rules forced plaintiff’s initial withdrawal of its formal
    appeal, and also defends the agency’s denial of plaintiff’s right to reinstatement of the formal
    appeal after the informal contractor review process was completed. Thus, at issue is not only
    what the agency’s review rules actually provide but also whether those rules are lawful. In the
    agency’s view, plaintiff took two voluntary steps by seeking informal contractor review and
    withdrawing its formal agency appeal, the combination of which extinguished its formal appeal
    rights.
    This case offers a cautionary tale to any provider navigating “the labyrinthine world of
    Medicare,” Adirondack Med. Ctr. v. Sebelius, 
    740 F.3d 692
    , 694 (D.C. Cir. 2014), and HHS’s
    complex system of reimbursements. Plaintiff withdrew its formal agency appeal based on an
    understanding of a rule making the healthcare provider “responsible” for doing so, combined
    with the further understanding that reinstatement of that formal appeal would be possible if
    sought. Plaintiff apparently also believed that the relevant regulations provided a right to
    maintain or revive its appeal as to any issue that the contractor reviewed, regardless of whether
    the contractor modified the outcome as to that issue. Indeed, the governing regulations and
    PRRB rules may allow for misinterpretation. Improving the clarity of the Medicare rules,
    however, is not a task for this Court.
    As explained more fully below, (a) the agency’s interpretation of its rules is reasonable
    and entitled to deference; (b) the rules, as so interpreted, are lawful; and (c) the agency correctly
    applied the rules under its interpretation. Presented with two routes by which it could obtain
    2
    review of Medicare reimbursement calculations with which it disagreed, plaintiff chose one route
    over the other, and must now bear the consequences of that choice. Accordingly, summary
    judgment is granted to defendant HHS and denied to plaintiff.
    I.     BACKGROUND
    The statutory and regulatory scheme underlying the parties’ dispute is described below,
    followed by the factual and procedural history in this case.
    A.      Statutory and Regulatory Background
    “Medicare is a federally funded program that reimburses healthcare providers for
    delivering medical care to qualifying elderly and disabled individuals.” New LifeCare Hosps. of
    N.C., LLC v. Becerra, 
    7 F.4th 1215
    , 1219 (D.C. Cir. 2021) (citing 
    42 U.S.C. § 1395
     et seq.).
    Participating healthcare providers, such as plaintiff, receive reimbursement from the HHS
    Secretary for health care services provided to enrollees. 42 U.S.C. § 1395g. Much of the
    administration of these payments is performed by private Medicare Administrative Contractors
    (“MACs”) acting on behalf of the Secretary. Id. §§ 1395h(a), 1395kk-1(a)(4); 
    42 C.F.R. §§ 421.100
    , 421.400.
    Each fiscal year, a participating hospital files a “cost report” with its MAC to provide the
    basis for calculating reimbursements due the hospital for services provided to beneficiaries over
    the course of the year. 
    42 C.F.R. §§ 413.20
    , 413.24(f); see also New LifeCare Hosps., 7 F.4th at
    1220 (“Healthcare providers file annual cost reports with these contractors, 
    42 C.F.R. § 413.20
    (b), and the contractors issue notices indicating which payments Medicare will cover, 
    id.
    § 405.1803(a).”). The MAC reviews and audits the cost report and thereafter issues a Notice of
    3
    Program Reimbursement (“NPR”) indicating the MAC’s determination of amounts to be paid to,
    or recouped from, the hospital. 
    42 C.F.R. §§ 405.1803
    , 413.60, 413.64(f).1
    “Providers can then appeal reimbursement decisions from the contractors to the Provider
    Reimbursement Review Board ([“PRRB”]), an administrative tribunal within HHS.” New
    LifeCare Hosps., 7 F.4th at 1220 (citing 42 U.S.C. § 1395oo(a)). The provider’s appeal of an
    NPR issued by the MAC must be within 180 days of its issuance if the provider is
    “dissatisfied . . . as to the amount of total program reimbursement due the provider” and “the
    amount in controversy is $10,000 or more.” 42 U.S.C. § 1395oo(a); 
    42 C.F.R. § 405.1835
    . The
    statute vests in the PRRB “full power and authority to make rules and establish procedures” to
    govern the appeals and review process. 42 U.S.C. § 1395oo(e). The PRRB has periodically
    issued such rules, which are not promulgated through a notice-and-comment process. As
    relevant here, one set of rules (the “2015 PRRB Rules”) was effective starting July 1, 2015, and
    another set (the “2018 PRRB Rules”) has been in effect since August 29, 2018. This action
    spans both versions of the PRRB Rules, but they are materially interchangeable in relevant
    respects other than numbering. A provider may seek judicial review, including in this Court, of
    any final PRRB decision within 60 days of its issuance. 42 U.S.C. § 1395oo(f)(1).2
    1
    A provider may receive an “interim” reimbursement in advance based on historical and/or estimated use of
    services. The NPR and subsequent payment (or recoupment, if Medicare had overpaid for the year in question)
    serves to “true-up” reimbursements to actual eligible costs incurred during the fiscal year. See 
    42 C.F.R. §§ 413.60
    ,
    413.64.
    2
    The PRRB’s “decision is final unless the Secretary—acting through the [Centers for Medicare & Medicaid
    Services (“CMS”)] Administrator—‘reverses, affirms, or modifies’ the [PRRB].” New LifeCare Hosps., 7 F.4th at
    1220 (citing 42 U.S.C. § 1395oo(f)(1); 
    42 C.F.R. § 405.1875
    (a)). A request for review of a PRRB decision must be
    submitted to the CMS Administrator within 15 days of receipt of the decision. 
    42 C.F.R. § 405.1875
    (c)(1).
    Whether to conduct such a review is within the sole discretion of the CMS Administrator. 
    Id.
     § 405.1875(c)(3).
    “From there, a provider may seek judicial review by filing a civil action in district court.” New LifeCare Hosps., 7
    F.4th at 1220–21 (citing 42 U.S.C. § 1395oo(f); 
    42 C.F.R. § 405.1877
    (b)). The possibility of the CMS
    Administrator’s discretionary review, however, does not create an additional exhaustion requirement. By regulation,
    “[a] provider is not required to seek Administrator review . . . first in order to seek judicial review of a Board
    decision.” 
    42 C.F.R. § 405.1877
    (a)(3)(ii).
    4
    In addition to the review mechanism available through the PRRB, the Secretary by
    regulation has also made available an alternative review process by which an NPR may be
    “reopened, with respect to specific findings on matters at issue in a determination or decision.”
    
    42 C.F.R. § 405.1885
    (a)(1). Such a process, the Secretary has recognized, may “hasten
    resolution of the case.” Medicare Program; Provider Reimbursement Determinations and
    Appeals, 
    73 Fed. Reg. 30,190
    , 30,232 (May 23, 2008). The MAC may—but is not required to—
    reopen a matter sua sponte or “by granting the request of the provider affected.” 
    42 C.F.R. § 405.1885
    (a)(2). A provider may still appeal revisions made by the MAC in the reopening
    process, but only with respect to “those matters that are specifically revised in a revised
    determination or decision.” 
    Id.
     § 405.1889(b); see also Def.’s Mem. Supp. Opp’n Pl.’s Mot.
    Summ. J. & Cross-Mot. Summ. J. (“Def.’s Opp’n”) at 4, ECF No. 16-1 (noting that “appeals of
    post-reopening revised NPRs are limited to the specific matters at issue that are adjusted by the
    Contractor in the revised NPR” (citing 
    42 C.F.R. § 405.1887
    (d))). A Revised NPR is “‘final and
    binding’ unless it is further revised as a result of an appeal or a later reopening.” Def.’s Opp’n at
    4 (quoting 
    42 C.F.R. § 405.1807
    ).
    MAC reopening and PRRB appeals may proceed simultaneously, since a MAC “may
    reopen . . . [a] determination that is currently pending on appeal before the [PRRB] or
    Administrator.” 
    42 C.F.R. § 405.1885
    (c)(3). Nevertheless, “[a]ny matter that is not specifically
    revised (including any matter that was reopened but not revised) may not be considered in any
    appeal of the revised determination or decision.” 
    Id.
     § 405.1889(b)(2). The PRRB appeal route
    and a reopening request to the MAC are thus distinct, concurrently available methods by which a
    provider may seek review of an NPR, though they become mutually exclusive when the MAC
    declines to revise an original determination on a reopened review.
    5
    The PRRB rules allow a provider to “request to withdraw an issue(s) or case” from
    appeal. 2015 PRRB Rule 48; see also 2018 PRRB Rule 46. This particular rule further states
    that “[i]t is the Provider’s responsibility to withdraw . . . an issue(s) for which the [MAC] has
    agreed to reopen the final determination for that issue(s) and attach a copy of the correspondence
    from the [MAC] where the [MAC] agreed to that reopening.” 2015 PRRB Rule 48. A provider
    “may request reinstatement of an issue(s) . . . within three years” of the PRRB’s receipt of the
    withdrawal request by filing a motion “in writing setting out the reasons for reinstatement.”
    2018 PRRB Rule 47.1. In the instance of issues withdrawn “because the [MAC] agreed to
    reopen/revise the cost report for that issue(s),” reinstatement is available if the MAC “failed to
    reopen the cost report and issue a new final determination (e.g., Revised NPR) for that issue(s) as
    agreed.” Id. R. 47.2.2.3 In other words, if the reopened MAC review is not completed, the
    provider may reinstate the formal appeal to the PRRB, but that reinstatement must be sought
    within three years from the date of withdrawal of the issue.
    Separately, the PRRB rules allow a provider to make a request for abeyance, which if
    granted “suspends action on an appeal until specified events occur or conditions are met.” 2015
    PRRB Rule 39(A); see also 2018 PRRB Rule 39. As relevant here, abeyance may be deemed
    appropriate “where the Provider can demonstrate that the case will be resolved without a hearing
    upon the occurrence of specified conditions or events.” 2015 PRRB Rule 39(A). Grants of
    abeyance are at the discretion of the PRRB. Id.
    3
    The Rule further requires that for such a reinstatement request, “the provider must attach a copy of its
    reopening request and the correspondence from the [MAC] where the [MAC] agreed to reopen the final
    determination for that issue(s).” 2018 PRRB Rule 47.2.2.

    B.       Factual Background
    Plaintiff is a Medicare-participating hospital in North Carolina that provides services to
    Medicare beneficiaries. Compl. ¶ 1, ECF No. 1. On June 9, 2015, Palmetto GBA, the MAC
    administering reimbursements for plaintiff, issued an NPR for the fiscal year ending September
    30, 2011, showing Medicare’s overpayment of $1,458,636 to plaintiff, which consequently owed
    that amount back to Medicare. Admin. Record (“AR”) at 70.4 Dissatisfied with the calculated
    reimbursement amounts, plaintiff filed with the PRRB an appeal, which was received on
    December 1, 2015, within the 180-day window provided by statute, 42 U.S.C. § 1395oo(a)(3).
    AR at 64–68. In its statement of issue attached to the appeal, plaintiff explained the dispute with
    the MAC’s “disallowance of [certain] Medicare bad debts,” such as deductible and coinsurance
    amounts not paid by beneficiaries when due, reimbursable by the Secretary under Medicare
    regulations provided that certain criteria are met. AR at 83–84; see also 
    42 C.F.R. § 413.89
    .
    Plaintiff also elected to pursue relief through the reopening process. When the PRRB
    appeal had been pending for about eight months, plaintiff wrote to the MAC “request[ing] a
    reopening” of the cost report. Def.’s Opp’n, Ex. C, August 19, 2016 Request for Reopening
    Medicare Cost Report at 1, ECF No. 16-4. In its letter, plaintiff identified six issues related to
    bad debt reimbursement in dispute and indicated that it had a pending appeal before the PRRB.
    4
    In compliance with D.D.C. LOCAL CIVIL RULE 7(n)(1), defendant submitted a certified list of the contents
    of the 84-page administrative record, see Certified List of Contents of Admin. Record (“AR Contents”), ECF No.
    13, and the parties separately docketed the portions of the administrative record cited or otherwise relied upon in the
    parties’ briefing, see J.A., ECF No. 22. For clarity, “AR” citations herein are to the full administrative record, rather
    than to the joint appendix. The only documents in the administrative record not filed with the Court are a request by
    plaintiff for PRRB-assisted mediation and an acknowledgment by the PRRB of that request. Compare AR Contents
    at 1, with J.A. at ii; see also 2015 PRRB Rule 43 (setting forth procedures for a mediation process). At the time of
    filing the PRRB appeal, plaintiff indicated that it was requesting mediation, AR at 66, and concurrently filed a
    separate letter containing a mediation request, AR Contents at 1, as required by the rule, 2015 PRRB Rule 43.2. The
    disposition of the mediation request is not in the record, but the chronology of events in the case suggests that the
    request for mediation became moot upon the MAC’s agreement to reopen the cost report with respect to the issues
    disputed by plaintiff.
    7
    
    Id.
     If the MAC agreed to reopen the cost report to examine these issues, plaintiff agreed to
    withdraw its appeal, but “reserve[d] the right to reinstate the appeal, if applicable, as outlined in
    [2015 PRRB] Rule 46.1.” 
    Id.
     The MAC agreed to reopen the cost report to examine the
    disputed issues on August 26, 2016. AR at 38–39. Plaintiff then, on August 29, 2016, wrote to
    the PRRB “request[ing] a withdrawal” of its appeal, “conditioned upon the [MAC’s] action
    through reopening of the September 30, 2011 cost report,” noting that it “reserve[d] the right to
    reinstate the appeal, if applicable.” AR at 34.
    The MAC performed a review and, on September 27, 2017, issued a Revised NPR that
    allowed reimbursement for some previously disallowed bad debts but continued to deny
    reimbursement for others. AR at 19 (indicating revisions to reimbursement amounts); 
    id.
     at 10–
    12, 14–15 (explaining the MAC’s determinations on reopening with respect to various of
    plaintiff’s objections). The effect of the Revised NPR was to increase the total reimbursement
    plaintiff was eligible to receive for the fiscal year by $833,242. AR at 19. Plaintiff did not
    appeal the Revised NPR to the PRRB, Def.’s Opp’n at 6, nor did it otherwise signal any
    objections within the 180-day statutory appeals window. Apparently still dissatisfied, nearly two
    years later, on August 13, 2019, plaintiff wrote to the PRRB “request[ing] reinstatement” of its
    original appeal because, plaintiff asserted, in the Revised NPR “[t]he MAC only partially
    accounted for the issues outlined.” AR at 22. This was within the requisite three years of the
    date plaintiff had withdrawn its PRRB appeal, see 2018 PRRB Rule 47.1, and thus the timeliness
    of this reinstatement request is not at issue here. Plaintiff did not, however, enclose any
    documents with its request nor elaborate on how the Revised NPR “only partially accounted” for
    the bad debt disputes.
    8
    The MAC wrote to the PRRB, on September 12, 2019, opposing reinstatement because,
    in its view, (a) plaintiff did not explain the reasons reinstatement was warranted, (b) the MAC
    did in fact reexamine the issues for which reopening was requested, as demonstrated by
    workpapers documenting such reexamination, (c) the MAC issued a Revised NPR, and (d) the
    MAC otherwise complied with the reopening agreement. AR at 4–5. Accordingly, the MAC
    argued, the condition in 2018 PRRB Rule 47.2.2 for reopening, that the MAC had “failed to
    reopen the cost report and issue a new final determination . . . as agreed,” was not met. Id. at 5.
    On February 19, 2020, the PRRB issued a decision denying reinstatement of plaintiff’s
    appeal. AR at 1–3. The principal reason given for the denial was that the MAC did, “in fact,
    issue[] a [Revised] NPR consistent with the agreed withdrawal.” AR at 2–3. As such, the PRRB
    concluded, plaintiff’s “right to reinstatement was extinguished when the [MAC] issued a new
    determination on September 27, 2017 that specifically dealt with the issues for which the
    Provider is seeking reinstatement.” Id. at 3 (footnote omitted) (emphasis in original).
    C.       Procedural Background
    On April 17, 2020, plaintiff filed the instant complaint challenging the PRRB’s February
    19, 2020 decision to deny reinstatement of its appeal. See Compl. ¶ 5. In a single count, the
    complaint alleges that the denial of reinstatement was “contrary to the Medicare statute,” id.
    ¶ 42, and violated the APA because the denial was arbitrary and capricious, was contrary to
    statute, lacked observance of required procedures, and was unsupported by substantial evidence,
    id. ¶ 43. The parties subsequently filed and briefed cross-motions for summary judgment and
    submitted, on June 17, 2021, a joint appendix containing relevant excerpts of the administrative
    record, J.A., ECF No. 22.5 The pending motions are now ripe for resolution.
    5
    In addition to the administrative record, plaintiff included, with its reply brief in support of its motion for
    summary judgment, Pl.’s Reply Mem. Supp. Mot. Summ. J. & Opp’n Def.’s Cross-Mot. Summ. J. (“Pl.’s Opp’n”) at
    9
    II.      LEGAL STANDARD
    A.       Administrative Procedure Act
    The APA provides for judicial review of any “final agency action for which there is no
    other adequate remedy in a court,” 
    5 U.S.C. § 704
    , and “instructs a reviewing court to set aside
    agency action found to be ‘arbitrary, capricious, an abuse of discretion, or otherwise not in
    accordance with law,’” Cigar Ass’n of Am. v. FDA, 
    964 F.3d 56
    , 61 (D.C. Cir. 2020) (quoting 
    5 U.S.C. § 706
    (2)(A)). This standard “‘requires agencies to engage in reasoned decisionmaking,’
    and . . . to reasonably explain to reviewing courts the bases for the actions they take and the
    conclusions they reach.” Brotherhood of Locomotive Eng’rs & Trainmen v. Fed. R.R. Admin.,
    
    972 F.3d 83
    , 115 (D.C. Cir. 2020) (quoting Dep’t of Homeland Sec. v. Regents of Univ. of Cal.
    (“Regents”), 
    140 S. Ct. 1891
    , 1905 (2020)). Judicial review of agency action is limited to “the
    grounds that the agency invoked when it took the action,” Regents, 140 S. Ct. at 1907 (quoting
    Michigan v. EPA, 
    576 U.S. 743
    , 758 (2015)), and the agency, too, “must defend its actions based
    on the reasons it gave when it acted,” id. at 1909.
    B.       Summary Judgment
    Pursuant to Federal Rule of Civil Procedure 56, “[a] party is entitled to summary
    judgment only if there is no genuine issue of material fact and judgment in the movant’s favor is
    proper as a matter of law.” Soundboard Ass’n v. FTC, 
    888 F.3d 1261
    , 1267 (D.C. Cir. 2018)
    (quoting Ctr. for Auto Safety v. Nat’l Highway Traffic Safety Admin., 
    452 F.3d 798
    , 805 (D.C.
    3–6, ECF No. 18, the following two extra-record statements made in 2021 by certain HHS personnel ostensibly
    interpreting the PRRB’s withdrawal rule at issue here: (1) an email from a “[p]aralegal [s]pecialist” at the Centers
    for Medicare & Medicaid Services (“CMS”), responding to an email inquiry in April 2021 by a consultant for
    plaintiff, advising that a provider “must withdraw an issue/case if the MAC has agreed to reopen the final
    determination for that issue(s),” Pl.’s Opp’n, Ex. 1, Exhibit 1 to Decl. of Josh Steedley, ECF No. 18-1; and (2) slides
    from a March 2021 conference presentation by three representatives of HHS, with a disclaimer that “[p]resenter
    comments do not reflect the views or positions of CMS or HHS,” likewise suggesting that PRRB rules “require[]
    withdrawal of issue if . . . MAC has agreed to reopen issue,” Pl.’s Opp’n, Ex. 2, Exhibit 1 to Decl. of Joseph D.
    Glazer, Esq., ECF No. 18-2.
    10
    Cir. 2006)); see also Fed. R. Civ. P. 56(a). In APA cases such as this one, involving cross-
    motions for summary judgment, “the district judge sits as an appellate tribunal. The ‘entire case’
    on review is a question of law.” Am. Bioscience, Inc. v. Thompson, 
    269 F.3d 1077
    , 1083–84
    (D.C. Cir. 2001) (footnote omitted) (collecting cases). Thus, a court need not and ought not
    engage in fact finding, since “[g]enerally speaking, district courts reviewing agency action under
    the APA’s arbitrary and capricious standard do not resolve factual issues, but operate instead as
    appellate courts resolving legal questions.” James Madison Ltd. by Hecht v. Ludwig, 
    82 F.3d 1085
    , 1096 (D.C. Cir. 1996); see also Lacson v. U.S. Dep’t of Homeland Sec., 
    726 F.3d 170
    , 171
    (D.C. Cir. 2013) (noting, in an APA case, that “determining the facts is generally the agency’s
    responsibility, not [the court’s]”). Judicial review, when available, is typically limited to the
    administrative record, since “[i]t is black-letter administrative law that in an [APA] case, a
    reviewing court should have before it neither more nor less information than did the agency
    when it made its decision.” CTS Corp. v. EPA, 
    759 F.3d 52
    , 64 (D.C. Cir. 2014) (internal
    quotation marks and citation omitted).
    III.   DISCUSSION
    Plaintiff argues that the PRRB’s withdrawal rule is mandatory for providers seeking a
    MAC reopening review and, as such, is unlawful and, in any event, that the PRRB failed
    properly to apply its reinstatement rule here. These assertions do not withstand scrutiny. HHS’s
    interpretation of the PRRB withdrawal rule as non-mandatory is reasonable and entitled to
    deference, and under this interpretation, the rule is unquestionably lawful. Furthermore, the
    plain text of the reinstatement rule demonstrates that plaintiff was not automatically entitled to
    reinstatement in this case. HHS is therefore entitled to summary judgment.
    11
    A.        Plaintiff Has Not Waived Its Challenge to PRRB Appeal Rules
    As an initial matter, HHS argues that plaintiff waived the argument that PRRB’s
    “mandatory withdrawal rule,” as characterized by plaintiff, is unlawful. According to HHS,
    plaintiff “could have argued before the [PRRB]” its grievance with the rule and, by failing to do
    so, is barred from raising the issue here. Def.’s Opp’n at 10. Citing “black-letter administrative
    law principles,” HHS argues that because plaintiff withdrew its PRRB appeal without suggesting
    either that it was required to do so or that such requirement was unlawful, plaintiff “deprived [the
    PRRB] of the opportunity to consider an ‘objection made at the time appropriate under its
    practice.’” 
    Id.
     at 10–11 (quoting United States v. L.A. Tucker Truck Lines, Inc., 
    344 U.S. 33
    , 37
    (1952)).
    The problem with this waiver argument is that plaintiff does not contend that a
    “mandatory withdrawal rule” is unlawful standing alone. Rather, plaintiff takes issue with “[t]he
    PRRB’s Mandatory Withdrawal Rule and subsequent refusal to reinstate the Hospital’s appeal
    after the MAC’s reopening did not fully resolve issues.” Pl.’s Mem. Supp. Mot. Summ. J. (“Pl.’s
    Mem.”) at 12, 15, 17, ECF No. 14. This distinction is essential; if the PRRB had reinstated
    plaintiff’s appeal, the earlier withdrawal, regardless whether deemed mandatory or not, would
    have worked no alleged deprivation of plaintiff’s statutory appeal rights and would not have been
    raised as a basis for review in this Court.
    Although framed as an argument that the mandatory withdrawal rule is in itself unlawful,
    the better description of the concern is that the unlawfulness stems from the combination of the
    purported mandatory withdrawal of issues from appeal with the denial of reinstatement of the
    withdrawn claim after the intermediary finishes its review without changing the calculations at
    issue. That result only became apparent when the PRRB issued its decision to deny
    reinstatement.
    12
    HHS correctly observes that its waiver argument sounds in the “issue exhaustion”
    doctrine. Def.’s Reply Pl.’s Opp’n Def.’s Cross-Mot. Summ. J. (“Def.’s Reply”) at 10, ECF No.
    20. As the Supreme Court has repeatedly noted, when, as here, the relevant statutes or
    regulations do not expressly impose an issue exhaustion requirement, “[t]he desirability of a
    court imposing a requirement of issue exhaustion depends on the degree to which the analogy to
    normal adversarial litigation applies in a particular administrative proceeding.” Carr v. Saul,
    
    141 S. Ct. 1352
    , 1358 (2021) (emphasis added) (quoting Sims v. Apfel, 
    530 U.S. 103
    , 109
    (2000)). Defendant unpersuasively suggests that these authorities should be read as inquiring
    into whether proceedings before a particular body “are generally adversarial in nature” rather
    than looking at “a specific process within the administrative scheme,” Def.’s Reply at 10–11, but
    the plain command of Carr and Sims suggests otherwise.
    Applied here, formal substantive review on the particulars of a Medicare reimbursement
    is unquestionably adversarial. The request for reinstatement, however, is less clearly so. To be
    sure, a “request for reinstatement is a motion” and must “set[] out the reasons for reinstatement,”
    2018 PRRB Rule 47.1, and “an opposing party may send a response,” 
    id.
     R. 44.3; see also 
    id.
     R.
    10.2 (allowing a response if the MAC opposes any type of “request”). At that point, however, a
    challenge to the rules themselves would have been premature given plaintiff’s apparent belief
    that it was entitled to reinstatement under those rules. The MAC’s letter of opposition to
    reinstatement said nothing about the circumstances of withdrawal or the interaction between the
    two rules, see AR at 4–5, and in any event, the PRRB rules do not contemplate a reply to such an
    opposition.
    HHS thus fails to identify precisely when in the administrative process leading up to the
    PRRB decision plaintiff was required to raise its argument that the PRRB withdrawal and
    13
    reinstatement rules are collectively unlawful. Plaintiff’s entitlement to judicial review, under 42
    U.S.C. § 1395oo(f)(1), arose at the same time as plaintiff became aware of the PRRB’s position
    that reinstatement was not available, the condition which in plaintiff’s view rendered the
    mandatory withdrawal rule unlawful. Thus, to the extent HHS’s administrative waiver argument
    is predicated on requiring plaintiff to have somehow raised this complaint before the agency
    earlier, this argument lacks merit.6 Accordingly, plaintiff has not waived this issue and may raise
    its challenge to the PRRB withdrawal rule here.
    B.       PRRB’s Interpretation of Its Own Withdrawal Rule Is Entitled to Deference
    Under the disputed PRRB rule, “[i]t is the provider’s responsibility to withdraw . . . an
    issue(s) for which the [MAC] has agreed to reopen the final determination for that issue(s).”
    2015 PRRB Rule 48. The parties vigorously debate whether the use of the word “responsibility”
    in this disputed rule means that a provider must withdraw its appeal as to an issue that is being
    reopened by agreement with the contractor. On the one hand, plaintiff describes this provision as
    a “Mandatory Withdrawal Rule” whereby “[t]he hospital has no choice regarding that
    withdrawal.” Pl.’s Mem. at 7, 9; see also id. at 12–13; Pl.’s Reply Mem. Supp. Mot. Summ. J. &
    Opp’n Def.’s Cross-Mot. Summ. J. (“Pl.’s Opp’n”) at 1–6, ECF No. 18. HHS, on the other hand,
    argues that the Rules elsewhere “use[] mandatory language like ‘must’ to establish a
    requirement” and “the word ‘responsibility’ is best read as not implying a command.” Def.’s
    Opp’n at 16–17. Both readings appear reasonable and, in this legal context, that ambiguity only
    helps the agency.
    6
    Plaintiff conceivably could have raised the issue by seeking discretionary review by the CMS
    Administrator after PRRB issued its decision denying reinstatement of the appeal, see supra note 2, but the language
    of the regulation governing judicial review expressly forecloses opting-out of Administrator review as a basis for a
    waiver argument, see 
    42 C.F.R. § 405.1877
    (a)(3)(ii) (“A provider is not required to seek Administrator review under
    [42 C.F.R.] § 405.1875(c) first in order to seek judicial review of a [PRRB] decision that is final and subject to
    judicial review under [42 U.S.C. § 1395oo(f)(1)].”).
    14
    When “interpreting a regulation involves a choice between (or among) more than one
    reasonable reading,” courts “should defer to the agency’s construction of its own regulation.”
    Kisor v. Wilkie, 
    139 S. Ct. 2400
    , 2411 (2019) (opinion of Kagan, J.) (recognizing the doctrine of
    deference set forth in Auer v. Robbins, 
    519 U.S. 452
     (1997)). Such deference, however, is not
    unlimited. First, the doctrine only applies “if a regulation is . . . genuinely ambiguous, even after
    a court has resorted to all the standard tools of interpretation.” Id. at 2414 (majority opinion).
    Second, even if genuine ambiguity is established, “the agency’s reading must still be
    ‘reasonable.’ In other words, it must come within the zone of ambiguity the court has identified
    after employing all its interpretive tools.” Id. at 2415–16 (citation omitted) (noting that even
    when the “tools” fail to resolve an ambiguity, they help to “establish the outer bounds of
    permissible interpretation”). HHS’s interpretation of the PRRB’s withdrawal rule as non-
    mandatory survives this analysis.7
    1.      The Disputed Rule Is Ambiguous and HHS’s Interpretation Is
    Reasonable
    HHS rightly concedes that the phrase “it is the responsibility of” in the disputed rule is
    ambiguous. Def.’s Opp’n at 18. As plaintiff suggests, the disputed rule can reasonably be read
    to require that when a provider secures the contractor’s agreement to reopen an issue, the
    provider then bears a duty to withdraw that issue from its PRRB appeal. The rule does not,
    however, use language, such as “shall” or “must,” that makes withdrawal clearly mandatory. To
    be sure, the absence of such “magic words” does not foreclose the possibility that the rule
    nonetheless states a requirement. Cf. In re Grand Jury Investigation, 
    315 F. Supp. 3d 602
    , 633–
    7
    Granting deference to HHS’s interpretation of 2015 PRRB Rule 48 and 2018 PRRB Rule 46—that this rule
    does not mandate withdrawal of an issue upon its reopening—renders moot plaintiff’s argument that the PRRB rules
    are contrary to statute. Plaintiff does not argue any impairment of its statutory appeal rights by a voluntary
    withdrawal rule.
    15
    34 (D.D.C. 2018), aff’d, 
    916 F.3d 1047
     (D.C. Cir. 2019) (noting, while analyzing a regulation
    employing the term “should” instead of “shall,” that “context is the key to determining whether
    the term ‘should’ carries a mandatory or permissive meaning”).
    HHS contends that the rule need not be read as stating a mandatory step, citing, for
    example, instances elsewhere in the Rules where the term “responsibility” is used but, HHS
    argues, does not “imply[] a command,” such as: (a) “It is the responsibility of the Provider to
    maintain record of delivery”; (b) “It is the Provider’s responsibility to maintain evidence of
    timely filing” and (c) “It is the responsibility of the party calling a remote witness to ensure that
    the witness has available both parties’ organized and labeled exhibits.” Def.’s Opp’n at 17.
    These examples simply beg the question, however, since each of HHS’s illustrative provisions
    appears susceptible to the same inquiry as to whether a requirement is established as opposed to
    a mere exhortation. HHS also leans on the Rules’ reference to “[a] provider’s request to
    withdraw an issue(s)” as militating against the provider being mandated to do so. See 
    id.
     at 16–
    17. This is similarly unhelpful, as the mere fact that a provider makes a “request” does not, in
    itself, make clear that the provider was not compelled by a rule to make said request.
    Finally, HHS argues, more persuasively, that “the non-mandatory character” of the rule is
    both evidenced and clarified by “the fact that the [PRRB] Rules gave Plaintiff a choice between
    requesting withdrawal of its appeal under Rule 46 and requesting that the appeal be held in
    abeyance or suspended under Rule 39,” id. at 18, while MAC reopening and review took place.
    Certainly, plaintiff’s exercise of the option of requesting abeyance would have better served its
    interests by putting it in the position of being able to revive its PRRB appeal after the MAC
    reopening and review. For the purpose of interpreting the withdrawal rule, however, this
    16
    argument is circular at best: the general availability of abeyance of an appeal need not have any
    effect on a rule that demands withdrawal of an issue upon reopening by an intermediary.8
    An easier path exists to conclude that the word “responsibility” admits of some
    ambiguity. This word can mean “[t]he quality, state, or condition of being duty-bound,
    answerable, or accountable,” BLACK’S LAW DICTIONARY (11th ed. 2019), which indeed suggests
    that a provider bears a “duty” to withdraw an issue on appeal upon a MAC agreement to reopen.
    The word can also mean “[t]hat for which one is answerable or accountable,” id., suggesting
    perhaps that if withdrawal is to be done, the provider is the person “answerable or accountable”
    for making it happen.
    Here, the relevant event triggering the “responsibility” in question is the “agree[ment]”
    between a provider and the MAC “to reopen the final determination for that issue(s).” 2015
    PRRB Rule 48. Such an agreement could plausibly yield withdrawal of the issue in the PRRB
    appeal in one of various ways: by the provider itself withdrawing the issue, by the MAC
    initiating the withdrawal, or by some automatic operation of law on account of the agreement.
    By stating that it “is the Provider’s responsibility to withdraw” the issue, id., the Rule can be read
    as stating that if the issue is to be withdrawn, the provider must be the one to do so, as opposed
    to the MAC, the PRRB, or some automatic process. Put another way, the Rule indicates who
    must effectuate the withdrawal if such withdrawal is desired, not whether withdrawal is a step
    8
    While not helpful in resolving the ambiguity in the rule, the existence of the abeyance option is nonetheless
    useful in demonstrating how the PRRB rules do not categorically abrogate providers’ statutory review rights. The
    parties agree that, absent a mandatory withdrawal rule, plaintiff had the option to request that its appeal be held in
    abeyance under PRRB Rule 39 while the MAC carried out its review after reopening. Pl.’s Mem. at 17; Def.’s
    Opp’n at 16. The parties appear to agree that the abeyance option, if exercised, would preserve a provider’s right to
    continue its appeal before the PRRB should it be dissatisfied with the Revised NPR—at least with respect to issues
    adjusted in the Revised NPR. Furthermore, it prevents the need for the provider to pursue the issues before the
    PRRB and the MAC simultaneously, thereby not frustrating any efficiency benefits achieved by attempting
    resolution through the reopening route.
    17
    that must be performed at all. In the absence of language clarifying the matter, the plain text of
    the Rule does not convincingly settle it one way or the other.
    The normal canons of interpretation provide little interpretive guidance here. In the
    context of the full Rule, other types of issues or cases are also “the Provider’s responsibility to
    withdraw”: (a) “an issue(s) or case that the Provider no longer intends to pursue,” (b) “an issue(s)
    or case in which an administrative resolution has been executed,” and (c) “a case in which all
    issues have been handled, whether by resolution, transfer, dismissal, or withdrawal.” 2005
    PRRB Rule 48. Under the canon of noscitur a sociis, whereby a word or phrase “is generally
    known by the company it keeps,” Agnew v. Gov’t of D.C., 
    920 F.3d 49
    , 56 (D.C. Cir. 2019), the
    character of these other types of issues for which a provider bears “responsibility” to withdraw
    may inform the character of the withdrawal “responsibility” for a MAC-reopened issue. Signs
    point in both directions, however. Withdrawal of an issue “that the Provider no longer intends to
    pursue” describes a clearly voluntary activity, while, by contrast, withdrawal of a case “in which
    an administrative resolution has been executed” or “in which all issues have been handled” could
    reasonably be read as a required withdrawal as a matter of docket management.
    Given that statutory interpretation “tools” fall short of definitively resolving any
    ambiguity in the construction of the withdrawal rule, the decisive question is whether HHS’s
    interpretation—that withdrawal is voluntary—is reasonable. For an agency’s interpretation of a
    regulation to receive deference, “it must come within the zone of ambiguity the court has
    identified after employing all its interpretive tools.” Kisor, 
    139 S. Ct. at
    2415–16. The above
    analysis identifying the existence of ambiguity has already answered this question:
    “responsibility” need not mean that the provider must withdraw an issue upon reopening.
    18
    2.       Plaintiff Cites No Authoritative Agency Sources for Its Preferred
    Interpretation
    In response to HHS’s assertion that the PRRB rules do not in fact require a provider to
    withdraw an issue or appeal when a MAC agrees to reopen a cost report, plaintiff offers two
    items of extra-record evidence, detailed supra note 5, that certain HHS staff members furnished
    information indicating that withdrawal is mandatory upon a MAC’s agreement to reopen an
    issue. Pl.’s Opp’n at 3–6. Specifically, plaintiff cites: (a) a PRRB staff email stating that a
    provider “must withdraw an issue/case if the MAC agreed to reopen the final determination,” in
    response to an April 2021 query to PRRB made by plaintiff’s consultant, id. at 4; and (b) a slide
    from a presentation by three “senior staff members at the Centers for Medicare and Medicaid
    Services” at an industry conference noting that “Board Rule 46 requires withdrawal of issue
    if . . . MAC has agreed to reopen issue,” id. at 4–6.9
    Assuming that these statements were in fact made by HHS staff reinforces the conclusion
    that the withdrawal rule is ambiguous, a point already conceded by HHS. Surely, the fact that
    various staff at, or associated with, PRRB represented in 2021 that the rule mandated withdrawal
    upon MAC reopening helps confirm that such an interpretation was a reasonable one for plaintiff
    to reach. The probative value of these statements, however, stops there. Not only do the
    statements postdate the February 2020 PRRB decision under review in this case and therefore
    were not before the agency at the time, see Def.’s Reply at 5, but also for the same timing reason,
    plaintiff does not—and cannot—argue that these statements were relied on by plaintiff in
    9
    HHS points out that plaintiff does not address why this extra-record evidence should be considered nor the
    legal standards applicable to such consideration. Def.’s Reply at 3–5. The use of such extra-record evidence in an
    APA case is “limited” and generally “to challenge gross procedural deficiencies—such as where the administrative
    record itself is so deficient as to preclude effective review.” Hill Dermaceuticals, Inc. v. FDA, 
    709 F.3d 44
    , 47
    (D.C. Cir. 2013) (per curiam). Notwithstanding any shortcomings in plaintiff’s legal support for consideration of
    this evidence, the staff statements highlighted by plaintiff do not affect the analysis of what the PRRB rules mean
    and whether HHS’s interpretation is entitled to deference.
    19
    determining how to pursue review of the disputed cost report, if such reliance matters at all.
    Finally, as HHS points out, plaintiff offers no evidence showing that any of the staff members
    making these statements was in a position to offer an authoritative, much less binding,
    interpretation of the withdrawal rule. 
    Id.
     at 6–7; cf. Kisor, 
    139 S. Ct. at 2416
     (noting that Auer
    deference is only afforded to regulatory interpretations that “emanate from those actors . . .
    understood to make authoritative policy in the relevant context”).10 In short, the two extra-record
    statements are not helpful to plaintiff’s position.
    3.       HHS Has Special Expertise Interpreting Medicare Rules
    For Kisor/Auer deference to be warranted, the interpretation of the regulation at issue
    must “in some way implicate [the agency’s] substantive expertise.” Kisor, 
    139 S. Ct. at 2417
    .
    Medicare, a statutory and regulatory scheme that the D.C. Circuit has described as a
    “labyrinthine world,” Adirondack Med. Ctr., 740 F.3d at 694, is prototypical subject matter for
    which specialized expertise is especially valuable. See Via Christi Hosps. Wichita, Inc. v.
    Burwell, 
    820 F.3d 451
    , 456 (D.C. Cir. 2016) (“We owe heightened deference to the Secretary’s
    interpretation of a complex and highly technical regulatory program such as Medicare.”
    (quotation marks and citation omitted)).
    10
    Plaintiff further draws upon its anecdotes of PRRB staff statements in 2021 by suggesting that should
    HHS’s interpretation of the withdrawal rule as non-mandatory be credited, additional discovery should be permitted
    as to “whether that is in fact how the agency read and applied the rule to Plaintiff (and other hospitals).” Pl.’s Opp’n
    at 7–8. This request faces the high hurdle of well-established law that “[d]iscovery typically is not available in APA
    cases.” Air Transp. Ass’n of Am. v. Nat’l Mediation Bd., 
    663 F.3d 476
    , 487 (D.C. Cir. 2011) (citation omitted).
    Rare exceptions may be granted when “a party makes a significant showing . . . that it will find material in the
    agency’s possession indicative of bad faith or an incomplete record,” 
    id.
     at 487–88, but plaintiff makes no such
    showing. Furthermore, plaintiff fails to identify how new evidence about PRRB’s understanding of its withdrawal
    rule would affect this case. While plaintiff queries whether the agency “read and applied the rule to Plaintiff” as
    non-mandatory, Pl.’s Opp’n at 7, it does not acknowledge that the agency at no point had to “appl[y]” the rule at all.
    Plaintiff withdrew its appeal without prompting by PRRB, leaving no reason for PRRB to contemplate whether such
    withdrawal was mandatory.
    20
    To be sure, the narrow question of regulatory interpretation posed here—whether a
    provider must withdraw from its appeal an issue that its MAC has agreed to reopen—does not
    seem enormously “complex” or “technical” in nature. Indeed, a court is eminently capable of
    construing the term “responsibility” when called upon to do so. In the context of a carefully
    calibrated scheme for determining Medicare reimbursements owed providers, however, the
    implications of one construction over another may be wide ranging. Would a mandatory
    withdrawal rule disincentivize providers from using the reopening process and thereby increase
    the overall burden on the PRRB? Would MACs alter their decisions as to whether to reopen
    issues if doing so affected appealability before the PRRB? Would the Secretary have established
    a reopening process if use of that process extinguished statutory appeal rights? These are policy
    judgments best assessed by the agency with the expertise and task of administering a complex
    government program, and in this instance the agency offers a reasonable construction of its own
    rule, rendering further inquiry unnecessary.
    C.      PRRB’s Reinstatement Rule Is Unambiguous and Was Correctly Applied
    While the parties focus primarily on the proper interpretation of the withdrawal rule, the
    PRRB’s decision not to reinstate plaintiff’s appeal requires some examination of the
    reinstatement rule as well. The operative 2018 version of Rule 47.2.2 reads: “Upon written
    motion, [PRRB] will also grant reinstatement of an issue(s)/case if a provider requested to
    withdraw an issue(s) from its case because the [MAC] agreed to reopen/revise the cost report for
    that issue(s) but failed to reopen the cost report and issue a new final determination (e.g.,
    Revised NPR) for that issue(s) as agreed.”
    Plaintiff argues that “[r]einstatement is nondiscretionary when the MAC fails to fully
    resolve the disputed issues that were originally appealed by the hospital” and since the MAC
    allegedly did not do so here, “[t]he PRRB’s refusal to reinstate the appeal thus violated the
    21
    PRRB’s own rules.” Pl.’s Mem. at 21–22. To the contrary, PRRB’s decision to deny
    reinstatement of the issue fits squarely within the parameters of the rule. See AR at 2–3
    (“[S]ince it is clear that the Medicare Contractor, in fact, issued a [Revised NPR] consistent with
    the agreed withdrawal, the Provider’s right to reinstatement was extinguished when the Medicare
    Contractor issued a new determination . . . that specifically dealt with the issues for which the
    Provider is seeking reinstatement.”).
    Plaintiff indisputably “requested to withdraw” its appeal, see AR at 35, and did so on
    account of the MAC’s declaration that same day about “hereby reopening [plaintiff’s] cost
    report” to examine issues including all those cited in the withdrawal letter, AR at 36. The MAC
    thereafter issued an “Amended Notice of Amount of Medicare Program Reimbursement” (the
    “Revised NPR”), AR at 19, which the PRRB found to be based on a review of all of the specific
    issues for which plaintiff had sought reopening, AR at 2–3. Plaintiff asserted that the Revised
    NPR “only partially accounted for the issues,” AR at 6, but dissatisfaction with the result of a
    review is not the same as having no review at all.
    Plaintiff is thus simply incorrect to assert that the MAC’s “cost report reopening and
    review process did not resolve fully the previously appealed issues that were the subject of the
    cost report reopening,” Pl.’s Opp’n at 1. On the contrary, the MAC resolved the issues “fully”
    and, indeed, in plaintiff’s favor—to the tune of $833,242—just not to plaintiff’s liking on each
    and every one of the six issues raised. Nowhere in the record or the briefing does plaintiff claim
    that the MAC, in preparing its Revised NPR, failed to examine any of the six issues prompting
    the reopening, nor that the Revised NPR failed to cover all those issues.
    Furthermore, even if the MAC failed to examine any reopened issue—despite its
    workpapers suggesting otherwise, AR at 2—plaintiff did not include in its reinstatement request,
    22
    which is the sole record evidence available to the agency reflecting plaintiff’s position, any
    information whatsoever about the nature of the purported deficiencies in the Revised NPR, nor
    did it identify what “part[]” of the issues the Revised NPR failed to resolve. AR at 6. On this
    meager record, plaintiff has fallen far short of demonstrating that the PRRB’s decision was in
    any way arbitrary or capricious. “[A] court is not to substitute its judgment for that of the
    agency” when reviewing agency decisions under this standard, Ascension Borgess Hosp. v.
    Becerra, No. 20-cv-139 (BAH), 
    2021 WL 3856621
    , at *4 (D.D.C. Aug. 30, 2021) (quoting
    Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983)), and here
    the “judgment” at issue is merely PRRB’s refusal to act on plaintiff’s conclusory assertion that
    the Revised NPR included some unspecified shortcomings.
    The lack of evidence of any shortcomings in the MAC review and ensuing Revised NPR
    is fatal to plaintiff’s claim that it was entitled to reinstatement under PRRB rules.11
    *    *     *
    The above analysis, examining the matter through the lens of the parties’ arguments, is
    sufficient to resolve the matter. The root cause of plaintiff’s predicament, however, may well be
    far simpler: the language of the governing regulations (not merely the PRRB rules) seems to
    foreclose a provider’s ability to avail itself of both the PRRB review route and the MAC
    reopening route, irrespective of the procedural choices it makes before the PRRB. So long as the
    11
    The result of this necessary conclusion is that plaintiff likely finds itself without any further avenue for
    administrative review of the cost report and reimbursement calculations at issue. HHS points out that “the result of
    a reopening is typically a revised NPR, which can itself be appealed within a 180-day period.” Def.’s Opp’n at 16
    (citing 
    42 C.F.R. § 405.1889
    (a)). Plaintiff made no such appeal—the window to do so has long since lapsed—and
    would not fare much better even if it had. As HHS also observes, “appeals of post-reopening revised NPRs are
    limited to the specific matters at issue that are adjusted by the [MAC] in the revised NPR.” 
    Id.
     at 4 (citing 
    42 C.F.R. § 405.1887
    (d)); see also Pl.’s Mem. at 4. Insofar as plaintiff continued to disagree with the MAC’s calculations on
    any item which the MAC did not adjust in the Revised NPR, plaintiff was foreclosed from filing a new appeal
    before the PRRB as to those items. See 
    42 C.F.R. § 405.1887
    (d).
    23
    MAC issues a Revised NPR as promised, by regulation that issuance appears to be the end of the
    line for those issues the MAC actually reviewed but did not revise. Per the plain text of the
    regulations, “[a]ny matter that is not specifically revised (including any matter that was reopened
    but not revised) may not be considered in any appeal of the revised determination or decision.”
    
    42 C.F.R. § 405.1889
    (b)(2) (emphasis added).12 Even if plaintiff had not withdrawn its appeal
    and had been entitled to resume it after issuance of the Revised NPR, the ensuing review would
    surely constitute “any appeal” of the Revised NPR, given that the original NPR would have been
    superseded.
    Insofar as that critical regulatory bar to further appeal controls the outcome, the
    distinctions raised by the parties—between withdrawal and abeyance, or between mandatory and
    voluntary withdrawal—matter little. HHS has set up a system where a provider can pursue an
    appeal before the PRRB as of right, or, with the MAC’s agreement, review of disputed items
    through the reopening process. So long as a provider receives the promised review through one
    route or the other, as plaintiff did here, it is not deprived of its right to contest the NPR.
    Plaintiff does not argue that 
    42 C.F.R. § 405.1889
    (b)(2) conflicts with the Medicare Act,
    for good reason. While plaintiff makes much of its “statutory appeal rights” of which it was
    12
    When promulgating the currently effective version of 
    42 C.F.R. § 405.1889
    , HHS expressly intended to
    constrain the scope of a post-reopening appeal. In Edgewater Hospital, Inc. v. Bowen, 
    857 F.2d 1123
     (7th Cir.
    1988), amended by 
    866 F.2d 228
     (7th Cir. 1989), the Seventh Circuit rejected HHS’s restrictive interpretation of the
    then-effective regulation, holding that the PRRB could review all items in a Revised NPR, not just those items
    changed on reopening, even where a provider had not timely filed an appeal to the initial NPR. See 
    id.
     at 1135–37
    (“It simply is nonsense to argue that the only matters which the provider can appeal are those actually changed by
    the [MAC].”). HHS maintained that the Edgewater court’s interpretation was incorrect, and in its 2008 rulemaking
    added the parenthetical “including any matter that was reopened but not revised,” 
    42 C.F.R. § 405.1889
    (b)(2), to
    effectively overrule Edgewater. See Medicare Program, 73 Fed. Reg. at 30,230–31. Oddly, the preamble
    accompanying the revised regulation nonetheless suggests that a provider may be able to “preserve” its appeal
    rights, by filing an appeal to the initial NPR, as to issues within the scope of a MAC reopening for which the MAC
    does not ultimately make revisions. See id. at 30,230 (“[T]o the extent that the appeal period has not already run by
    the time that the provider receives the reopening notice, the provider should file an appeal if it wishes to preserve the
    right to appeal matters covered by the notice of reopening.”). It is not clear, however, how such “preserv[ation]”
    squares with the regulation’s textual exclusion of unrevised items from “any appeal.”
    24
    ostensibly deprived, see Pl.’s Mem. at 12, the existence of such a right does not mean that
    plaintiff is entitled to a specific type of hearing, before a specific body, irrespective of its election
    to avail itself of an alternative route for resolution. The very section of the statute that creates
    the PRRB, 42 U.S.C. § 1395oo(a), also vests in the PRRB the “full power and authority to make
    rules and establish procedures . . . which are necessary or appropriate to carry out the provisions
    of this section,” id. § 1395oo(e). The D.C. Circuit has long held that regulations that constrain
    the scope of post-reopening appeals are permissible rules and procedures of this type. See HCA
    Health Servs. of Okla., Inc. v. Shalala, 
    27 F.3d 614
    , 620–21 (D.C. Cir. 1994). As the agency
    points out, rules regarding the appeals process are essential to the effective docket management
    of the PRRB and can include “the possibility of dismissal as a sanction for noncompliance,”
    Def.’s Opp’n at 13–14—a sanction far harsher than what plaintiff experienced here.
    In this case, plaintiff chose to divert its review to the more informal MAC reopening
    process and bore the docket-management consequence that when the MAC’s reopening
    completed with the issuance of a Revised NPR, by regulation “any appeal” of “a matter that was
    reopened but not revised” was thereby foreclosed, 
    42 C.F.R. § 405.1889
    (b)(2). Nobody disputes,
    however, that plaintiff had the option to pursue its appeal at the PRRB from start to finish
    without detouring to MAC reopening. Likewise, nobody disputes that had the MAC failed to
    perform the promised review and issue a Revised NPR, plaintiff could have resumed the PRRB
    appeal. Simply put, at no point was plaintiff forced to give up its “statutory appeal rights.”
    25
    IV.    CONCLUSION
    For the foregoing reasons, the PRRB rules challenged by plaintiff are lawful and were
    correctly applied in this case. Accordingly, plaintiff’s motion for summary judgment is
    DENIED and HHS’s cross-motion for summary judgment is GRANTED.
    An order consistent with this Memorandum Opinion will be entered contemporaneously.
