    Like many diabetics, Linda Smith uses a prescribed continuous glucose
    monitor (CGM) to track and regulate her glucose levels. When Smith purchased
    her CGM and its necessary supplies between 2016 and 2018, she sought
    reimbursement for her expenses through her medical insurance program,
    Medicare Part B. Medicare administrators denied her claims. Relying on a 2017
    ruling issued by the Centers for Medicare and Medicaid Services (CMS),
    Medicare administrators concluded that Smith’s CGM is not “primarily and
    customarily used to serve a medical purpose” and therefore is not covered by
    Medicare Part B. Smith appealed the denial of her reimbursement claims through
    the multistage Medicare claims review process. At each stage, the respective
    adjudicator confirmed the denial of her claims.
    Smith then sued the Secretary of the Department of Health and Human
    Services in federal court, seeking monetary, injunctive, and declaratory relief.
    Contending that her CGM and supplies satisfied the requirements for Medicare
    coverage, Smith requested that the district court (1) order the Secretary to pay her
    claims; (2) declare that CGMs are covered by Medicare; and (3) set aside the
    2017 ruling as unlawful because it did not go through the proper rulemaking
    process.
    Instead of asking the court to uphold the denial of Smith’s claims, the
    Secretary admitted that Smith’s claims should have been covered and that the
    agency erred by denying her claims. The Secretary requested a remand so the
    agency could reimburse Smith’s claims. Rather than accept the Secretary’s
    2
    Appellate Case: 22-4012   Document: 010110723774       Date Filed: 08/12/2022   Page: 3
    admission of error, Smith argued that the Secretary only admitted error to avoid
    judicial review of the legality of the 2017 ruling.
    During Smith’s litigation, CMS changed its Medicare coverage policy for
    CGMs. Prompted by several adverse district court rulings, CMS promulgated a
    formal rule in December 2021 classifying CGMs as durable medical equipment
    covered by Medicare Part B. But the rule applied only to claims for equipment
    received after February 28, 2022, so pending claims for equipment received prior
    to that date were not covered by the new rule.
    Considering the new rule and the Secretary’s confession of error, the
    district court in January 2022 remanded the case to the Secretary with
    instructions to pay Smith’s claims. The district court did not rule on Smith’s
    pending motions regarding her equitable relief claims; instead, the court denied
    them as moot. Smith moved to alter or amend the judgment, contending that her
    equitable claims were still live, but the district court denied the motion.
    Smith appealed, arguing that her equitable claims are justiciable because
    the 2017 ruling has not been formally rescinded and Medicare administrators can
    still rely on the ruling to deny claims for equipment received prior to
    February 28, 2022. But in May 2022—shortly before oral argument in this
    case—the Secretary issued a new ruling. The 2022 ruling expressly rescinded the
    2017 ruling and ordered Medicare administrators to approve CGM claims for
    equipment received prior to February 28, 2022. The Secretary asserted the 2022
    ruling further rendered Smith’s claims moot.

    Appellate Case: 22-4012     Document: 010110723774      Date Filed: 08/12/2022    Page: 4
    We agree with the Secretary that Smith’s claims are moot. Taken together,
    the December 2021 final rule and the 2022 CMS ruling ensure that pending and
    future claims for CGMs, including the equipment owned by Smith, will be
    covered by Medicare. Because the recent regulatory developments moot Smith’s
    equitable claims, we do not have jurisdiction to consider Smith’s appeal. We
    further conclude that although CMS voluntarily changed its CGM coverage policy
    during this litigation, the voluntary cessation doctrine to avoid mootness does not
    apply.
    I. Background
    Diabetes is a disease that affects how the body handles glucose, a sugar
    that is the main source of energy for many cells and tissues. Glucose enters the
    bloodstream through food or after being produced in the liver. Insulin, which is
    produced by the pancreas, helps the body process glucose by moving glucose
    from the bloodstream to cells and tissues. When the body does not produce
    enough insulin, glucose can build up in the bloodstream, causing severe health
    problems, such as heart disease, stroke, kidney failure, or even death.
    To avoid a medical emergency, diabetics must constantly monitor their
    glucose levels. The traditional means of doing so is with a blood glucose test,
    which involves pricking a finger and placing a drop of blood on a test strip to
    determine current glucose levels. Depending on the results of the test, diabetics
    may need to take insulin or ingest glucose to adjust their blood sugar levels.
    While blood glucose tests are accurate, they can be painful and inconvenient for
    4
    Appellate Case: 22-4012   Document: 010110723774     Date Filed: 08/12/2022      Page: 5
    many diabetics, some of whom must wake up several times throughout the night
    to perform a test.
    To address these issues, researchers developed CGMs, which are capable of
    automatically measuring blood glucose levels at short intervals—some monitors
    can take readings as frequently as every five minutes. To use a CGM, diabetics
    insert a disposable sensor underneath their skin. The sensor detects glucose
    levels and sends the data via a transmitter to a display monitor. Some CGM
    devices include insulin pumps, which dispense insulin automatically if there is a
    high glucose reading. Diabetics typically need to replace a sensor once a week, a
    transmitter once every few months, and a monitor after several years. CGMs are
    often preferred because they monitor glucose levels automatically and more
    frequently than blood glucose tests. More frequent readings decrease the risk that
    a sudden onset of symptoms will lead to a medical emergency. They also lead to
    better overall glucose-level control, which can prevent long-term health
    problems.
    Smith’s Medicare Claims
    Linda Smith has suffered from diabetes for over 55 years. Her condition is
    particularly dangerous because she has hypoglycemic unawareness, which means
    she is unable to physically sense when her blood glucose levels are too low.
    Smith is also prone to rapid and unpredictable changes in her glucose levels.
    Because Smith often has few physical warnings of an impending diabetic
    emergency, Smith must be vigilant in monitoring her glucose levels—failing to
    5
    Appellate Case: 22-4012   Document: 010110723774     Date Filed: 08/12/2022   Page: 6
    do so could be catastrophic for her. On at least one occasion, Smith lost
    consciousness and had to be hospitalized.
    To better manage Smith’s diabetes, a doctor prescribed her a Medtronic
    MiniMed 630G CGM with disposable sensors. Smith, who has Medicare Part B
    health insurance, filed Medicare reimbursement claims for the monitor and
    sensors. Specifically, Smith sought reimbursement for a MiniMed monitor
    prescribed to her in December 2016, and disposable glucose sensors she received
    in November 2017 and May 2018.
    Medicare administrators denied Smith’s claims. The administrators
    determined that Smith’s specific monitor and supplies were not “durable medical
    equipment” covered by Medicare. Smith appealed her claims all the way to the
    Medicare Appeals Council, but her claims were rejected. 1
    Medicare administrators denied Smith’s claims based on CMS-1682-R, a
    ruling issued by CMS in January 2017. That ruling—which is binding on
    Medicare administrators and constitutes an “official statement[] of agency policy
    1
    Medicare reimbursement claims must go through the following administrative
    process before a beneficiary may seek judicial review: (1) initial coverage
    determination made by a CMS administrative contractor; (2) redetermination
    decision made by same contractor; (3) reconsideration by a qualified independent
    contractor; (4) review by an administrative law judge (ALJ) (subject to a
    minimum amount-in-controversy requirement); and (5) de novo review by the
    Medicare Appeals Council (MAC), which constitutes a final decision by the
    Secretary.

    Appellate Case: 22-4012   Document: 010110723774        Date Filed: 08/12/2022   Page: 7
    and interpretation”—explains that a CGM will only be covered by Medicare if it
    meets the definition of “durable medical equipment.” App., Vol. 2 at 314. The
    Medicare regulations define “durable medical equipment” as
    [E]quipment, furnished by a supplier or a home health
    agency that meets the following conditions:
    (1) Can withstand repeated use.
    (2) Effective with respect to items classified as [durable
    medical equipment] after January 1, 2012, has an
    expected life of at least 3 years.
    (3) Is primarily and customarily used to serve a medical
    purpose.
    (4) Generally is not useful to an individual in the absence
    of an illness or injury.
    (5) Is appropriate for use in the home.
    
    42 C.F.R. § 414.202
    . In CMS-1682-R, CMS explained that some CGMs require a
    separate blood glucose test to confirm blood sugar levels before corrective
    measures can be taken. Because these CGMs cannot be used independently to
    make diabetes treatment decisions, CMS concluded that such devices—which
    CMS refers to as “non-therapeutic” or “adjunctive” devices—are not “primarily
    and customarily used to serve a medical purpose” and thus do not meet the
    definition of durable medical equipment. App., Vol. 1 at 85–87. CMS reasoned
    that only those CGMs “approved by the [Food and Drug Administration] for use
    in place of a blood glucose monitor for making diabetes treatment decisions” are
    durable medical equipment. 
    Id. at 92
     (emphasis added).
    7
    Appellate Case: 22-4012   Document: 010110723774        Date Filed: 08/12/2022   Page: 8
    Medicare administrators and an administrative law judge determined that
    CMS-1682-R precluded coverage for Smith’s claims because the Food and Drug
    Administration “has not approved the beneficiary’s CGM system . . . as a
    replacement for a blood glucose monitor.” App., Vol. 2 at 320. In a final agency
    decision, the Medicare Appeals Council adopted the reasoning of the
    administrative law judge, ruled that Smith’s claims were not covered by
    Medicare, and deemed Smith financially responsible for the incurred expenses.
    Procedural Background
    Having exhausted her administrative remedies, Smith sued the Secretary of
    the Department of Health and Human Services in federal court. 2 In addition to
    seeking monetary reimbursement for her claims, Smith also sought injunctive and
    declaratory relief. Specifically, she requested that the district court (1) set aside
    CMS-1682-R because it did not go through notice and comment rulemaking as
    required by statute; (2) declare that CGMs are durable medical equipment,
    regardless of whether they replace blood glucose tests; and (3) declare that the
    Secretary’s denials of CGM claims were unsupported by substantial evidence,
    arbitrary and capricious, abuses of discretion, and not in accordance with the law.
    Rather than contest Smith’s claims, the Secretary admitted that Medicare
    administrators erred by denying coverage. The Secretary explained that because
    Smith’s CGM also serves as an insulin pump, it meets the definition of durable
    2
    CMS is part of the Department of Health and Human Services.
    8
    Appellate Case: 22-4012   Document: 010110723774       Date Filed: 08/12/2022    Page: 9
    medical equipment under the Medicare statute and regulations. Based on this
    admission of error, the Secretary requested that the district court enter judgment
    in favor of Smith and remand to the agency for payment of Smith’s claims. 3
    Despite the Secretary’s confession of error, the district court allowed the
    case to proceed. Shortly after the Secretary filed his answer, Smith moved for
    summary judgment. Smith argued that the district court should vacate CMS-
    1682-R because the ruling did not go through the notice and comment process as
    required by 42 U.S.C. § 1395hh. In a separate summary judgment motion, Smith
    argued that the Secretary should be collaterally estopped from litigating the issue
    of whether Smith’s CGM is durable medical equipment because an administrative
    law judge had previously ruled that Smith’s monitor was covered.
    In response, the Secretary contended that the district court does not have
    the power to vacate CMS-1682-R because the Medicare statute does not authorize
    a court to set aside agency actions such as CMS rulings, citing 
    42 U.S.C. §§ 405
    (g), 1395ii. The Secretary also alerted the district court to the fact that in
    November 2020, CMS published a notice of proposed rulemaking stating that the
    agency planned to change its policy regarding coverage of CGMs. Unlike CMS-
    3
    The Secretary initially said that only Smith’s claim for the monitor itself should
    be paid on remand. While the Secretary acknowledged that administrators erred
    in denying Smith’s other two claims for the sensors, the Secretary explained that
    it had yet to be determined “whether the sensors should be covered as reasonable
    and necessary for the operation of the insulin pump.” App., Vol. 1 at 38. The
    Secretary later amended his position based on intervening regulation changes and
    requested that the district court “remand to the Secretary for payment of [all]
    three claims.” 
    Id. at 271
    .
    9
    Appellate Case: 22-4012   Document: 010110723774      Date Filed: 08/12/2022   Page: 10
    1682-R, the new rule would classify CGMs as durable medical equipment
    regardless of whether they can be relied on to make diabetes treatment decisions
    without the use of a separate blood glucose test. See 
    85 Fed. Reg. 70,358
    (Nov. 4, 2020). The Secretary explained to the district court that the “proposed
    rule would supersede [CMS-1682-R], if finalized, and in doing so would moot
    Mrs. Smith’s claim for vacatur.” App., Vol. 1 at 263.
    Following a public comment period, CMS issued a final rule in December
    2021 classifying CGMs, transmitters, and sensors as durable medical equipment
    covered by Medicare Part B. See 
    86 Fed. Reg. 73,860
     (Dec. 28, 2021) (“Final
    Rule”). Based on this regulatory change, the Secretary renewed his request for
    the court to enter judgment in favor of Smith and to remand the case. In January
    2022, the district court entered a judgment remanding the matter to the Secretary
    with instructions to pay Smith’s three claims. In a docket text order, the court
    denied Smith’s pending summary judgment motions regarding CMS-1682-R and
    collateral estoppel as moot.
    Finding the court’s order and judgment inadequate, Smith moved to alter or
    amend the judgment, arguing that her motions were not moot because she sought
    equitable relief and collateral estoppel, both of which the court had not addressed,
    and the Secretary’s concession did not resolve. Smith contended that the Final
    Rule issued by CMS did not moot her claims because the rule only applies to
    claims for CGMs and supplies received after February 28, 2022. Smith informed
    the court that she had other reimbursement claims pending before the agency for
    10
    Appellate Case: 22-4012    Document: 010110723774        Date Filed: 08/12/2022    Page: 11
    CGM sensors she received on July 14, 2021. Since Medicare administrators had
    denied those July 2021 claims even after the Secretary confessed error as to
    Smith’s 2016, 2017, and 2018 claims, Smith asserted there was a reasonable
    probability that the Secretary would continue to deny pending CGM claims based
    on CMS-1682-R. Therefore, Smith argued her equitable relief claims still
    presented a live controversy.
    The district court denied Smith’s motion to alter or amend the judgment. It
    explained that Smith’s pending motions were moot because the court granted
    judgment in Smith’s favor. The court further explained that “while [Smith]
    appears to desire additional relief . . . the court granted [Smith] all of the relief
    authorized by statute.” App., Vol. 1 at 11 (citing 
    42 U.S.C. §§ 405
    (g), 1395ii).
    Subsequent Developments
    After Smith filed her notice of appeal, CMS sent a Technical Direction
    Letter to all Medicare administrative contractors. The Letter explained that
    although the coverage and payment provisions of the Final Rule only apply to
    CGMs and supplies received after February 28, 2022, contractors should approve
    valid reimbursement claims for equipment received before that date. See
    Technical Direction Letter 220257, Docket 20-1, Olsen v. Becerra, No. 21-cv-326
    11
    Appellate Case: 22-4012    Document: 010110723774       Date Filed: 08/12/2022    Page: 12
    (E.D. Wash. Feb. 25, 2022). 4 The Letter said that by applying the coverage
    provisions of the Final Rule retroactively to pending claims, CMS will “avoid
    expending administrative resources on further application of [CMS-1682-R] on
    CGMs and additional appeals challenging application of [CMS-1682-R].” 
    Id. at 2
    . Even though the Letter is not binding on Medicare contractors, the Secretary
    contends on appeal that the Letter serves as further evidence that Smith’s
    remaining claims are moot because “future valid claims for continuous-glucose-
    monitor supplies should be covered regardless of the date of service.” Resp. Br.
    at 26 n.2. Smith insists that because the Letter is not binding and CMS-1682-R
    has not been formally rescinded, there is no guarantee that pending claims for
    CGMs will be approved.
    On May 13, 2022—four days before the parties’ oral argument in this
    case—CMS issued a binding ruling to formally implement its policy of applying
    the Final Rule retroactively to claims for CGM supplies received prior to
    February 28, 2022. See CMS-1738-R, available at https://www.cms.gov/
    regulations-and-guidanceguidancerulingscms-rulings/cms-1738-r. In CMS-1738-
    4
    Because the Letter was issued after the district court’s entry of final judgment,
    it was not before the district court and is not part of the record on appeal.
    Nevertheless, we may take judicial notice of this publicly filed letter for the first
    time on appeal. See Winzler v. Toyota Motor Sales U.S.A., Inc., 
    681 F.3d 1208
    ,
    1213 (10th Cir. 2012).

    Appellate Case: 22-4012    Document: 010110723774        Date Filed: 08/12/2022   Page: 13
    R, CMS expressly rescinded CMS-1682-R and prohibited its further application
    to pending claims. 5
    II. Analysis
    Smith contends the district court erred by denying her equitable claims as
    moot. The Secretary counters that even if Smith’s equitable claims were still live
    when the district court declined to address them, they have since become moot
    due to the recent regulatory changes affecting coverage of CGMs. The Secretary
    also argues that the voluntary cessation doctrine—which obviates mootness—
    does not apply here because there is no indication that the Secretary changed his
    coverage policy in response to this litigation or that he will reverse course once
    this litigation concludes.
    We dismiss the appeal as moot. The Final Rule concerning future claims
    for CGMs, coupled with the recent issuance of Technical Direction Letter 220257
    5
    Specifically, CMS-1738-R states:
    This Ruling provides notice of the CMS Administrator’s
    determination to rescind a January 17, 2017 CMS Ruling
    (CMS-1682-R) . . . the substantive CGM classification,
    coverage, and payment policies established by the
    December 2021 final rule shall be applied to claims for a
    CGM monitor or receiver and/or its necessary supplies
    and accessories where either: (1) a valid CGM claim or
    valid CGM appeal was pending as of February 28, 2022;
    or (2) the right to submit a valid CGM claim or file a valid
    CGM appeal had not expired as of February 28, 2022.
    CMS-1738-R at 1–2.
    13
    Appellate Case: 22-4012    Document: 010110723774       Date Filed: 08/12/2022    Page: 14
    and CMS-1738-R, fully redress Smith’s equitable claims. Vacating CMS-1682-R
    and declaring that CGMs are durable medical equipment covered by Medicare
    would have no effect because CMS has already rescinded CMS-1682-R and
    issued a formal rule classifying CGMs and their supplies as durable medical
    equipment. In short, Smith no longer suffers from an actual or imminent injury
    that can be redressed by this court.
    We also conclude that the voluntary cessation doctrine does not apply.
    Although CMS changed its CGM coverage policy during this litigation, mooting
    Smith’s claims, the Secretary has met his burden of establishing that the policy
    change will not be rescinded after this case concludes.
    A. Mootness
    Article III of the Constitution limits the jurisdiction of federal courts to
    actual “Cases” and “Controversies.” U.S. Const. art. III, § 2; Genesis Healthcare
    Corp. v. Symczyk, 
    569 U.S. 66
    , 71 (2013). The case-or-controversy requirement
    “ensures that the Federal Judiciary confines itself to its constitutionally limited
    role of adjudicating actual and concrete disputes, the resolutions of which have
    direct consequences on the parties involved.” Genesis Healthcare,

    In her complaint, Smith requested that the district court enter an order

    (1) setting aside CMS-1682-R and its determination that
    CGMs that do not completely replace finger prick/test
    strips are not [durable medical equipment] within the
    meaning of 42 U.S.C. § 1395x(n) and 
    42 C.F.R. § 414.202
    ;
    (2) finding that CGMs (whether they completely replace
    finger prick/test strips or not) are [durable medical
    equipment] within the meaning of 42 U.S.C. § 1395x(n)
    and 
    42 C.F.R. § 414.202
    ;
    (3) finding the Secretary’s denials of CGM coverage on
    the grounds that a CGM is not [durable medical
    equipment] is not supported by substantial evidence, are
    16
    Appellate Case: 22-4012   Document: 010110723774      Date Filed: 08/12/2022   Page: 17
    arbitrary and capricious, an abuse of discretion, and not
    in accordance with the law.
    App., Vol. 1 at 35. 6
    The Secretary contends that intervening events during this litigation have
    rendered Smith’s claims moot. We agree. The Final Rule, the Technical
    Direction Letter, and CMS-1738-R already classify CGM systems as durable
    medical equipment and mandate coverage for pending and future Medicare
    reimbursement claims. Thus, granting Smith any of the relief requested above
    would have no real-world effect.
    We begin with Smith’s first request for relief. Smith alleges that CMS-
    1682-R should be set aside because it was issued “without observance of the
    procedure required by law (e.g., notice and comment [rulemaking]).” 
    Id.
     at 32–
    34. Smith argues that because her Medicare reimbursement claims have been
    continuously denied based on CMS-1682-R, invalidating the ruling would
    eliminate any basis for the Secretary to deny her claims for CGM supplies in the
    future.
    Smith’s argument fails because CMS formally rescinded CMS-1682-R and
    replaced it with the Final Rule and CMS-1738-R, both of which mandate
    Medicare coverage for CGMs. The Final Rule, which became effective on
    6
    Smith also requested that the district court order “the Secretary to provide
    coverage for the CGM claims at issue in this case.” App., Vol. 1 at 35. Because
    the district court indisputably ruled in Smith’s favor on that claim, we need not
    address whether the claim is moot.
    17
    Appellate Case: 22-4012   Document: 010110723774       Date Filed: 08/12/2022   Page: 18
    February 28, 2022, ensures coverage for CGM supplies received after that date.
    CMS-1738-R applies the same coverage provisions to CGM claims that were
    pending as of February 28, 2022, or where the right to submit a claim or appeal
    had not expired as of February 28, 2022. Collectively, these changes mean that
    the Secretary no longer has any basis upon which to deny Smith’s pending or
    future claims. 7 Because Smith’s claims for her CGM supplies are now covered by
    Medicare, invalidating CMS-1682-R would provide Smith no further relief. Her
    first claim is therefore moot. See Church of Scientology of Cal. v. United States,
    
    506 U.S. 9
    , 12 (1992) (“[I]f an event occurs while a case is pending on appeal
    that makes it impossible for the court to grant ‘any effectual relief whatever’ to a
    prevailing party, the appeal must be dismissed.” (citation omitted)).
    For similar reasons, Smith’s second claim for declaratory relief is also
    moot. Smith asked the district court to declare that all CGMs are durable medical
    equipment under the Medicare statute and regulations. To begin with, Smith only
    7
    Because Smith’s equitable relief claims did not become moot until CMS issued
    CMS-1738-R in May 2022, the district court should not have found those claims
    moot in January 2022. The district court apparently denied Smith’s pending
    motions as moot in part because the Final Rule rescinded CMS-1682-R. But the
    Final Rule only applies to claims for equipment received after February 28, 2022.
    Claims for equipment received before that date—such as Smith’s July 2021
    claims that were pending before the agency—could still be denied under CMS-
    1682-R. Since Smith still faced a risk that her pending claims would be denied,
    Smith retained a legally cognizable interest in the outcome of the case and her
    equitable claims remained live. It was not until CMS issued CMS-1738-R—
    applying the Final Rule retroactively to claims for equipment supplied prior to
    February 28, 2022, and expressly rescinding CMS-1682-R—that Smith’s claims
    became moot. After that ruling went into effect, Smith no longer faced a risk of
    imminent harm from her claims being denied.
    18
    Appellate Case: 22-4012    Document: 010110723774        Date Filed: 08/12/2022   Page: 19
    has standing to challenge the denial of her specific CGM because a declaration
    that other glucose monitors are covered by Medicare would not redress any injury
    suffered by Smith. See Warth v. Seldin, 
    422 U.S. 490
    , 499 (1975) (“[T]he
    plaintiff generally must assert his own legal rights and interests, and cannot rest
    his claim to relief on the legal rights or interests of third parties.”). Regardless,
    the Final Rule and CMS-1738-R address Smith’s concerns and grant Smith the
    full relief she seeks. The Final Rule recognizes that CGMs—irrespective of
    whether they complement a blood glucose test—are “primarily and customarily
    used to serve a medical purpose” and therefore meet the definition of durable
    medical equipment. 86 Fed. Reg. at 73,899. Similarly, CMS-1738-R adopts the
    Final Rule’s coverage provisions and expressly rescinds CMS-1682-R. See CMS-
    1738-R at 11 (“CMS-1682-R, is hereby rescinded and shall not be applied to any
    additional CGM claims under Part B or Part C, as applicable, or to any further
    administrative appeals of CGM claims.”). These regulatory changes make clear
    that CMS now classifies CGMs as durable medical equipment. Smith’s
    declaratory relief claim is moot.
    Smith’s final request for relief—declaring that the Secretary’s repeated
    denials of CGM claims was wrongful—is also moot. Smith requested that the
    district court declare that “the Secretary’s denials of CGM coverage on the
    grounds that a CGM is not [durable medical equipment] [are] not supported by
    substantial evidence, are arbitrary and capricious, an abuse of discretion, and not
    in accordance with the law.” App., Vol. 1 at 35. Smith asserts that this
    19
    Appellate Case: 22-4012    Document: 010110723774      Date Filed: 08/12/2022   Page: 20
    declaration would prevent the Secretary from denying future CGM claims based
    on an improper interpretation of the regulatory definition of “durable medical
    equipment.” Like Smith’s other requests for relief, this request is moot because
    Smith no longer suffers from an imminent injury that would be redressed by
    declaring that the Secretary’s previous denials of coverage were improper. In
    short, Smith seeks “a retrospective opinion that [s]he was wrongly harmed by the
    defendant.” See Jordan, 
    654 F.3d at 1025
    . Without a redressable injury, such a
    declaration would be nothing more than an advisory opinion. See TransUnion
    LLC v. Ramirez, 
    141 S. Ct. 2190
    , 2203 (2021) (“Under Article III, federal courts
    do not adjudicate hypothetical or abstract disputes.”).
    Smith also requested a separate ruling on the issue of whether the Secretary
    is collaterally estopped from litigating CGM coverage because an administrative
    law judge previously determined that Smith’s CGM and supplies are covered by
    Medicare. As Smith notes, CMS-1738-R and the Final Rule do not address the
    issue of whether prior administrative law judge or district court decisions
    preclude the Secretary from re-litigating the coverage of CGMs. But the “crucial
    question” for mootness is whether “granting a present determination of the issues
    offered . . . will have some effect in the real world.” Davidson, 
    236 F.3d at 1182
    (quotations and citation omitted). Because a ruling on collateral estoppel would
    not redress any actual or imminent injury suffered by Smith, we do not have
    jurisdiction to consider the issue.
    20
    Appellate Case: 22-4012   Document: 010110723774       Date Filed: 08/12/2022    Page: 21
    In sum, Smith has won all the relief she sought when she commenced this
    litigation. The Secretary has agreed to pay Smith’s denied claims, 8 rescinded
    CMS-1682-R, and recognized CGMs as durable medical equipment covered by
    Medicare. Based on Smith’s alleged injuries, there is no further relief that can be
    afforded to Smith.
    B. Voluntary Cessation
    We now turn to the question of whether the voluntary cessation doctrine
    applies.
    Although a live controversy must exist at all stages of litigation, “a
    defendant cannot automatically moot a case simply by ending its unlawful
    conduct once sued.” Already, 
    568 U.S. at 91
    . “Otherwise, a defendant could
    engage in unlawful conduct, stop when sued to have the case declared moot, then
    pick up where he left off, repeating this cycle until he achieves all his unlawful
    ends.” 
    Id.
     To address this concern, the Supreme Court has held that “a defendant
    claiming that its voluntary compliance moots a case bears the formidable burden
    of showing that it is absolutely clear the allegedly wrongful behavior could not
    reasonably be expected to recur.” 
    Id.
     (citation omitted).
    8
    According to the Secretary, Smith’s previously denied CGM claims have all
    been paid, including her claim for disposable sensors received in July 2021 after
    the filing of this case. See Resp. Br. at 24 (“CMS reprocessed and paid plaintiff’s
    claim for disposable sensors received on July 14, 2021); Aple. Supp. Br. at 13
    (“[T]he claims under review have been paid.”).
    21
    Appellate Case: 22-4012   Document: 010110723774       Date Filed: 08/12/2022    Page: 22
    Although the defendant faces a heavy burden in undermining the plaintiff’s
    invocation of the voluntary cessation doctrine, we do not require a defendant to
    show that it would be impossible for him to resume his allegedly wrongful
    conduct. “For the voluntary cessation exception to apply, ‘we must be convinced
    that the allegedly wrongful behavior could not reasonably be expected to recur
    . . . not that there is no possibility.’” Prison Legal News, 944 F.3d at 881 n.20
    (quoting Brown v. Buhman, 
    822 F.3d 1151
    , 1175 (10th Cir. 2016)). For that
    reason, “[a] case ceases to be a live controversy if the possibility of recurrence of
    the challenged conduct is only a speculative contingency.” Rio Grande Silvery
    Minnow, 
    601 F.3d at 1117
     (quotations omitted and alterations incorporated).
    When a plaintiff seeks to set aside the policy of a government agency, the
    rescission or modification of that policy can moot the challenge. 9 
    Id.
     Further,
    the “mere possibility that an agency might rescind amendments to its actions or
    regulations does not enliven a moot controversy.” 
    Id.
     (quotations and citation
    omitted); see also 
    id. at 1116
     (“[E]ven when a legislative body has the power to
    reenact an ordinance or statute, ordinarily an amendment or repeal of it moots a
    case challenging the ordinance or statute.”).
    9
    We have opined in past mootness cases that we may afford a government
    official’s voluntary conduct “more solicitude” than that of private actors. Rio
    Grande Silvery Minnow, 
    601 F.3d at
    1116 n.15 (quoting Ragsdale v. Turnock,
    
    841 F.2d 1358
    , 1365 (7th Cir. 1988)); Prison Legal News, 944 F.3d at 881. But
    as the Supreme Court reminds us, government actors still bear the “heavy” burden
    of making “absolutely clear that the allegedly wrongful behavior could not
    reasonably be expected to recur.” West Virginia, 142 S. Ct. at 2607 (quotations
    and citation omitted).
    22
    Appellate Case: 22-4012   Document: 010110723774       Date Filed: 08/12/2022    Page: 23
    Smith claims (1) the Secretary changed his policy regarding coverage of
    CGMs solely for the purpose of evading judicial review; and (2) it can be
    reasonably expected that the Secretary will resume denying CGM claims once
    this litigation concludes. We disagree for two reasons. First, the timing of the
    Secretary’s policy change toward CGMs suggests that the Secretary did not
    voluntarily change his conduct to moot Smith’s litigation. Second, there is a
    minimal risk that the Secretary will suddenly revert to his rescinded policy of
    denying CGM claims given the wholesale change in policy that has developed
    over the past several years. To undo his policy recognizing CGMs as durable
    medical equipment, the Secretary would need to take the unlikely steps of
    disavowing his previous support for the coverage of CGMs, replacing the Final
    Rule—which can only be done after a notice and comment period, rescinding the
    Technical Direction Letter, and withdrawing CMS-1738-R.
    We begin by examining the timing of the Secretary’s voluntary cessation of
    the challenged conduct. Based on the sequence of events that led to CMS
    changing its CGM coverage policy, we cannot conclude that the Secretary
    voluntarily ceased denying CGM claims as a temporary measure to moot Smith’s
    claims. See Brown, 822 F.3d at 1171 (“[W]e have indicated that mootness is
    more likely if . . . the case in question was the catalyst for the agency’s adoption
    of the new policy.” (quoting Rosebrock v. Mathis, 
    745 F.3d 963
    , 972 (9th Cir.
    2014))). Although CMS did not issue the Final Rule providing Medicare
    coverage for CGMs until after this case commenced, CMS initiated the
    23
    Appellate Case: 22-4012    Document: 010110723774       Date Filed: 08/12/2022     Page: 24
    rulemaking process well before this litigation. In November 2020—several
    months before the Medicare Appeals Council had even denied Smith’s claims—
    CMS published a proposed rule to classify CGMs as durable medical equipment
    under Medicare Part B. See 85 Fed. Reg. at 70,358. CMS explained that the
    proposed change in policy was due in part to several district courts rejecting the
    reasoning of CMS-1682-R that CGMs “are not primarily and customarily used to
    serve a medical purpose.” Id. at 70,401. While the outcome of other cases seems
    to have prompted the proposed rule change, the timing of the proposed rule in
    relation to Smith’s case forecloses the possibility that the Secretary stopped
    denying CGM claims solely to avoid judicial review in Smith’s case.
    While we agree with Smith that the timing of CMS-1738-R—issued four
    days before oral argument—invites greater scrutiny than the timing of the Final
    Rule, we conclude that the timing of CMS-1738-R does not support an
    application of the voluntary cessation doctrine. First of all, Smith’s case is not
    the only case affected by the Final Rule or CMS-1738-R. As Smith repeatedly
    points out in her briefs, the Secretary has denied thousands of other CGM claims,
    forcing other beneficiaries to litigate their claims. We find it unlikely that the
    Secretary would issue CMS-1738-R merely to moot Smith’s claims given the
    abundance of other CGM claims and related litigation. But even if the change in
    policy was prompted by Smith’s litigation, “that does not necessarily make it
    suspect.” See Brown, 822 F.3d at 1171. We have found that a “government
    official’s decision to adopt a policy in the context of litigation may actually make
    24
    Appellate Case: 22-4012    Document: 010110723774       Date Filed: 08/12/2022   Page: 25
    it more likely the policy will be followed, especially with respect to the plaintiffs
    in that particular case.” Id. (emphasis added). CMS stated in CMS-1738-R that
    it decided to change its policy on pending CGM claims “to bring an orderly
    conclusion to pending (and potentially forthcoming) administrative claims and
    appeals relating to the requirements for classification, coverage, and payment of
    CGM claims.” CMS-1738-R at 6. While issuing CMS-1738-R may have mooted
    Smith’s current claims, rescinding the ruling after Smith’s case concludes would
    reopen the floodgates for other beneficiaries to challenge the denial of their CGM
    claims. Such a shift in policy would impede CMS’s stated goal of “avoid[ing] the
    expenditure of administrative resources on further application of [CMS-1682-R].”
    Id.
    Second, we consider whether it can be reasonably expected that the
    Secretary will resume his allegedly wrongful conduct once this litigation ends.
    Smith contends that as soon as the Secretary is no longer under the watchful eye
    of the federal judiciary, the Secretary will revive CMS-1682-R and Medicare
    administrators will resume denying CGM claims.
    We find this argument entirely speculative. While it is true that the
    Secretary long refused to recognize CGMs as durable medical equipment, the
    Secretary has spent the past two years formally revoking that policy. It cannot
    “reasonably be expected” that CMS would suddenly revert to denying CGM
    claims when it has gone through the lengthy rulemaking process and concluded in
    the Final Rule, Technical Direction Letter, and CMS-1738-R that CGMs are
    25
    Appellate Case: 22-4012   Document: 010110723774      Date Filed: 08/12/2022   Page: 26
    durable medical equipment covered by Medicare. Unraveling those regulatory
    changes seems improbable, especially given that CMS has determined it to be
    more cost effective to pay pending CGM claims rather than continue litigating
    them. See Brown, 822 F.3d at 1167 (“Most cases that deny mootness following
    government officials’ voluntary cessation rely on clear showings of reluctant
    submission by governmental actors and a desire to return to the old ways.”
    (cleaned up)).
    To be sure, the Letter and CMS-1738-R could be rescinded with relative
    ease. But we think it unlikely that the Secretary would rescind both and resume
    applying CMS-1682-R when that ruling directly conflicts with the coverage
    provisions of the Final Rule, which could only be replaced after another notice
    and comment period. See id. at 1171 (finding mootness because the risk that the
    county attorney’s office “will revoke or ignore” its new policy is “minimal at
    best”). Although not set in stone, the Final Rule, Technical Direction Letter, and
    CMS-1738-R collectively “foreclose a reasonable chance of recurrence of the
    challenged conduct.” See Prison Legal News, 944 F.3d at 884 (citation omitted).
    Finally, Smith argues the voluntary cessation doctrine should apply
    because the Final Rule and CMS-1738-R have not “completely and irrevocably
    eradicated the effects” of the Secretary’s wrongful conduct. See Rio Grande
    Silvery Minnow, 
    601 F.3d at 1115
     (quoting Davis, 
    440 U.S. at 631
    ). Even if the
    Final Rule and CMS-1738-R provide coverage for pending and future claims,
    Smith contends the rulings provide no relief to the thousands of Medicare
    26
    Appellate Case: 22-4012     Document: 010110723774     Date Filed: 08/12/2022   Page: 27
    beneficiaries whose claims were denied in the past and the thousands more who
    never submitted claims or requested equipment due to the prohibitive coverage
    provisions of CMS-1682-R. But the injuries suffered by other beneficiaries have
    no bearing on whether Smith’s claims are live. Intervening events—which
    include the district court’s order for the Secretary to pay Smith’s claims, the Final
    Rule, the Technical Direction Letter, and CMS-1738-R—have remedied the
    effects of the Secretary’s allegedly wrongful conduct towards Smith, the only
    plaintiff in this case.
    In sum, the Secretary took concrete steps to implement a new policy—
    through formal rulemaking and a binding CMS ruling—that cannot be easily
    reversed. The voluntary cessation doctrine does not apply.
    III. Conclusion
    For the foregoing reasons, we dismiss the appeal as moot.
