    MEMORANDUM OPINION
    I.     INTRODUCTION
    Plaintiff StimLabs, LLC (“StimLabs”) is a biotechnology company that develops and sells
    products for wound care and amniotic fluid allografts. At issue in this case are two of its
    products—Ascent and Corplex P—which are categorized as human cell, tissue, and cellular and
    tissue-based products, or HCT/Ps. StimLabs’ Ascent and Corplex P “are used to cushion and
    protect open wound environments and to cushion, protect, and supplement fluid environments such
    as synovial joints and tendons, and are distinct from drugs and biologicals, which require metabolic
    activity to achieve a therapeutic effect.” Two companies that use those products join as plaintiffs:
    Plaintiff Anesthesia and Pain Consultants, PC (“APC”) is a physician-owned corporation that
    provides medical care, and Plaintiff Wound Institute of America, Inc. (“Wound Institute”) is a
    medical practice focused on surgical and non-surgical wound care.
    Plaintiffs brought this action to challenge purported policies barring reimbursement for the
    use of Ascent and Corplex P under the Medicare program. Plaintiffs allege that the Secretary of
    Health and Human Services (the “Secretary”) and the Administrator of the Center for Medicare
    and Medicaid Services (“CMS”) (together, “Defendants”) unlawfully bypassed the notice-and-
    comment-rulemaking requirement for policies that change a substantive legal standard governing
    Medicare coverage and payment, and that Defendants applied those policy changes retroactively,
    contrary to law. Additionally, Plaintiffs assert that Defendants’ decision to stop covering Ascent
    and Corplex P is arbitrary and capricious under the Administrative Procedure Act (“APA”).
    Before the court are Plaintiffs’ motion for a preliminary injunction and Defendants’ motion
    to dismiss. The court concludes that Plaintiffs failed to exhaust their administrative remedies
    before filing suit.     Therefore, the court lacks subject matter jurisdiction over this action.
    Accordingly, Defendants’ motion to dismiss is granted and Plaintiffs’ motion for a preliminary
    injunction is denied.
    II.    BACKGROUND
    A.      The Medicare Program and Coverage for Use of HCT/Ps
    The Medicare program is a nationwide health insurance program for the aged, blind, and
    disabled. Part B of the program covers hospital-outpatient services, physician services, and other
    services not covered by Part A. Among the covered services under Part B are “drugs and
    biologicals which are not usually self-administered by the patient.” 42 U.S.C. § 1395x(s)(2)(A).
    The Medicare program will not cover any service that is “not reasonable and necessary for the
    diagnosis or treatment of illness or injury or to improve the functioning of a malformed body
    member.” Id. § 1395y(a)(1)(A). The Secretary’s regulations limit Medicare coverage only to drug
    products that have been approved by the U.S. Food and Drug Administration (“FDA”).
    
    42 C.F.R. § 410.29
     (2021). The regulations purportedly do “not require prior FDA approval for
    HCT/Ps,” like Ascent and Corplex P, “that are not regulated as drugs.” Compl. for Inj. and Decl.
    Relief, Mandamus, and Relief Under the All Writs Act, ECF No. 1 [hereinafter Compl.] ¶ 1.
    2
    Further, the Secretary has not published a final rule addressing Medicare coverage for HCT/Ps.
    
    Id.
     ¶ 64
    In November 2017, the FDA published guidance setting out the “FDA’s position for
    manufacturers” on what qualified as “minimal manipulation and homologous use”—a requirement
    for products to be regulated as HCT/Ps. 
    Id. ¶ 49
    . The guidance provided a period of time during
    which the FDA “intended to exercise enforcement discretion while manufacturers determined
    whether their products met the HCT/P criteria, as freshly interpreted by the FDA,” relieving
    manufacturers “of all premarket review and approval requirements” during this period. 
    Id.
     The
    enforcement discretion was set to expire on May 31, 2021. 
    Id. ¶ 50
    .
    On December 6, 2019, in the midst of the enforcement discretion period, the FDA issued
    a Guidance and Public Safety Notification (“FDA Notification”) that declared a specific subset of
    HCT/Ps as “experimental exosome biological products.” 
    Id. ¶ 2
    . The FDA Notification did not
    apply to all HCT/Ps and, in fact, was “entirely silent as to HCT/Ps derived from amniotic cells,
    placental cells, or tissues,” like StimLab’s Ascent and Corplex P, which are not exosomes.
    
    Id. ¶ 59
    .
    Nevertheless, in July 2021, after the FDA’s enforcement discretion period ended, Medicare
    Administrative Contractors (“MACs”) began denying reimbursement claims for Ascent and
    Corplex P based on the FDA Notification. 
    Id. ¶¶ 2
    , 52–53. According to Plaintiffs, this change
    marked a sharp departure from Medicare’s past coverage of Ascent and Corplex P. Before May
    31, 2021, MACs “routinely covered and paid Medicare Part B claims for products composed of
    amniotic tissue, including Ascent and Corplex P, as reasonable and necessary.”          
    Id. ¶ 52
    .
    However, in July 2021, “MACs began retroactively reopening claims” for Ascent and Corplex,
    without providing any notice to providers and suppliers of the change in Medicare coverage for
    3
    HCT/Ps, and without engaging in notice-and-comment rulemaking. 
    Id. ¶ 53
    . In short, MACs
    began refusing to reimburse for the use of Ascent and Corplex P in treatment, despite the fact that
    they are not “experimental exosome biological products” and have not been categorized as such
    by the FDA. 
    Id. ¶ 3
    . One MAC denied claims for services using Corplex P on the grounds that
    “Corplex P was not approved by the FDA,” and another MAC denied claims for Ascent because
    “Ascent was experimental/investigational.” 
    Id. ¶¶ 54, 56
    .
    After a MAC began denying claims for Ascent, StimLabs took the matter up with CMS. It
    “contacted the Director, Coverage and Analysis Group at CMS to discuss the actions
    [and] . . . [o]ver the course of several months, StimLabs engaged in multiple email exchanges and
    several telephone calls to discuss the use of an unpublished policy memorandum, the absence of
    any notice that the coverage criteria had changed, and the use of a rationale that did not reflect the
    legal status of Ascent as an HCT/P.” 
    Id. ¶ 55
    .
    B.      The Technical Direction Letters
    In February 2022, CMS issued two Technical Direction Letters (“TDLs”) regarding
    HCT/Ps.     The TDLs (1) “declared that certain manipulated amniotic and/or placental tissue
    biologics for injections were experimental exosome biologic products and (2) directed the MACs
    to re-open and adjust any paid claims for dates of service December 6, 2019, and later for those
    HCT/Ps identified in the TDLs.” 
    Id. ¶ 61
     (internal quotation marks omitted). The “TDLs also
    directed the MACs to apply automatic claims denials, rather than the claim-by-claim
    determinations that otherwise apply in the absence of [a national coverage determination] or [a
    local coverage determination], specifically identifying . . . Ascent and Corplex P for such
    automatic denial.” 
    Id.
     In addition to failing to adopt the TDLs through notice-and-comment,
    according to Plaintiffs, CMS further sought to obscure its actions. “CMS expressly directed the
    4
    MACs not to reference CMS’s TDLs in any ad hoc provider education regarding the Policies.”
    
    Id.
    On February 23, 2022, “MACs released policies on their websites stating that Medicare
    claims for manipulated, reconstituted, or injectable amniotic, or placental products would no
    longer be covered under Medicare.” 
    Id. ¶ 58
    . The policies further stated that “claims with dates
    of service on or after December 9, 2019, would be reopened and retroactively denied.” 
    Id.
     In
    early March 2022, “StimLabs again contacted CMS as well as the FDA to seek a resolution of the
    matter.” 
    Id. ¶ 60
    . StimLabs met with the director of CMS’s Coverage and Analysis Group and
    had a conference call with an FDA Associate Director for Product Management, but the “contacts
    proved fruitless.” 
    Id.
    The TDLs were short-lived. On March 25, 2022, CMS issued a third TDL that withdrew
    the first two. 
    Id. ¶ 62
    . CMS instructed MACs to “suspend automatic denials of claims for amniotic
    and placental tissue product injections,” to “institute claim-by-claim review to determine whether
    a claim meets the reasonable and necessary criteria,” and “to reopen any claims that had been
    processed under the automatic denials.” 
    Id.
     Despite the withdrawal of the TDLs, Plaintiffs allege
    that MACs “reinstituted their denials of Medicare claims for HCT/P products including Ascent
    and Corplex P . . . on the same rationale articulated in the TDLs, asserting that the claims can be
    denied because neither Ascent nor Corplex P has received premarket approval from the FDA, even
    though FDA approval is not required for HCT/P products.” 
    Id. ¶ 63
    . In other words, Plaintiffs
    claim that, despite the February 2022 TDLs being rescinded, MACs continued to deny coverage
    for Ascent and Corplex P under their reasoning.
    This alleged new unwritten coverage policy threatens the viability of Plaintiffs’ businesses.
    StimLabs says “that a loss of Medicare coverage for Corplex P alone will result in a loss of
    5
    approximately 20% of its current revenue that cannot be compensated through damages.” 
    Id. ¶ 65
    .
    Plaintiff APC has submitted Medicare reimbursement claims for its use of Ascent, and it has
    received overpayment notices totaling approximately $200,000. 
    Id. ¶ 67
    . If forced to repay the
    overpayment demand, APC would have to close its practice. 
    Id. ¶¶ 67, 85
    . The Complaint does
    not allege that Plaintiff Wound Institute has received an overpayment notice but does state that it
    has “lost revenue” and “faces significant damage to its professional reputation and good will.” 
    Id. ¶ 103
    .
    C.     Procedural History
    Plaintiffs filed this action and moved for preliminary injunctive and declaratory relief on
    July 8, 2022. See Compl.; Pls.’ Mot. for Inj. and Decl. Relief, ECF No. 6 [hereinafter Pls.’ Mot.],
    Pls.’ Mem. of P. & A. in Supp. of Pls.’ Mot., ECF No. 6-1 [hereinafter Pls.’ Inj. Mem.]. Plaintiffs
    allege that CMS’s unwritten blanket policy of denying coverage for the use of Ascent and
    Corplex P (1) violates 42 U.S.C. § 1395hh, which “expressly requires that a change in a
    substantive legal standard governing the scope of Medicare benefits or payments be subject to
    notice and comment rulemaking,” (2) is arbitrary and capricious in violation of Section 706 of
    APA, and (3) runs afoul of both 42 U.S.C. § 1395hh(e) and 
    42 C.F.R. § 405.980
     due to the
    retroactive application of the new policy without a finding of good cause. Pls.’ Inj. Mem. at 2.
    Plaintiffs ask the court to declare the Secretary’s actions invalid and unlawful, and to enjoin the
    Secretary from implementing them. 
    Id. at 45
    .
    Defendants filed a motion to dismiss on August 15, 2022. Defs.’ Mem. of P. & A. in Supp.
    of their Mot. and in Opp’n to Pls.’ Mot., ECF No. 17 [hereinafter Defs.’ Mot.]. As grounds for
    dismissal, Defendants argue both that the court lacks subject matter jurisdiction and that Plaintiffs
    6
    have failed to state a claim. See 
    id.
     Because the court dismisses this action on jurisdictional
    grounds, it does not address the sufficiency of Plaintiffs’ pleading.
    III.   DISCUSSION
    A.      Federal Question Jurisdiction: 
    28 U.S.C. § 1331
    The parties’ primary jurisdictional dispute centers on whether the court lacks general
    federal question jurisdiction to hear this action. It is “well established that section 405(h) of the
    Social Security Act (as incorporated into the Medicare Act through 42 U.S.C. § 1395ii) expressly
    limits the availability of general federal question jurisdiction in the Medicare context.” California
    Clinical Lab’y Ass’n v. Sec’y of Health & Hum. Servs., 
    104 F. Supp. 3d 66
    , 80 (D.D.C. 2015); 
    42 U.S.C. § 405
    (h) (“No action . . . shall be brought under section 1331 . . . of Title 28 to recover on
    any claim arising under” the Medicare Act). Section 405(h) “channels most, if not all, Medicare
    claims through [the agency] review system.” Shalala v. Ill. Council on Long Term Care, Inc., 
    529 U.S. 1
    , 8 (2000). Generally speaking, only after exhausting agency review procedures can
    claimants “seek judicial review [in federal court] pursuant to the Medicare Act.” Council for
    Urological Ints. v. Sebelius, 
    668 F.3d 704
    , 706 (D.C. Cir. 2011); see 42 U.S.C. § 1395ff(b)(1)(A)
    (providing for “judicial review of the Secretary’s final decision” following an administrative
    hearing).
    “This nearly absolute channeling requirement assures the agency greater opportunity to
    apply, interpret, or revise policies, regulations, or statutes without possibly premature interference
    by individual courts applying ‘ripeness’ and ‘exhaustion’ exceptions case by case.” Ill. Council,
    
    529 U.S. at 2
    . The Supreme Court has recognized that the “assurance comes at the price of
    occasional individual, delay-related hardship, but paying such a price in the context of a massive,
    complex health and safety program such as Medicare was justified in the judgment of Congress.”
    7
    
    Id.
     Thus, section 405(h) “is intended to postpone judicial review, not totally preclude it.” Council
    for Urological Ints., 668 F.3d at 708.
    In Illinois Council, the Court recognized an exception to the channeling requirement. The
    Court said that “§ 1395ii does not apply § 405(h) where application of § 405(h) would not simply
    channel review through the agency, but would mean no review at all.” Ill. Council, 
    529 U.S. at 19
     (emphasis added). In other words, for claims arising under the Medicare Act, if the channeling
    requirement leads to a “complete preclusion of judicial review,” a party need not present and
    exhaust its claims before coming to federal court. 
    Id. at 23
    . The Illinois Council exception is a
    narrow one, however. It is “not intended to allow section 1331 federal question jurisdiction in
    every case where section 405(h) would prevent a particular individual or entity from seeking
    judicial review.” Council for Urological Ints., 668 F.3d at 711.
    Taken together, these principles require a “three-step analysis” to assess “whether a court
    has subject matter jurisdiction to hear a claim related to Medicare.” Sensory Neurostimulation,
    Inc. v. Azar, 
    977 F.3d 969
    , 976 (9th Cir. 2020). First, the court must determine whether the claim
    “arises under” the Medicare Act. 
    Id.
     If it does, the court next “must decide whether the plaintiff
    has satisfied the channeling requirements by properly presenting the claim and exhausting the
    appropriate administrative channel.” 
    Id.
     Finally, if plaintiff has not satisfied the channeling
    requirement, the court must inquire whether the “no review at all” exception applies. 
    Id.
     “If it
    [does], the plaintiff may proceed in court under 
    28 U.S.C. § 1331
     or some other jurisdictional
    predicate. If not, the plaintiff’s claim cannot proceed and must be dismissed for lack of subject
    matter jurisdiction.” 
    Id.
    Here, the parties agree that Plaintiffs’ claims “arise under” the Medicare Act and that
    Plaintiffs have not satisfied the channeling requirement. Defs.’ Mot. at 10–17; Pls.’ Mem. of L.
    8
    in Opp. to Defs.’ Mot., ECF No. 23 [hereinafter Pls.’ Reply], at 7–12. Their dispute is over whether
    Plaintiffs meet the Illinois Council “no review at all” exception. Defs.’ Mot. at 16–17; Pls.’ Reply
    at 7–12.
    Plaintiffs effectively concede that APC and Wound Institute cannot meet the exception.
    Both are Medicare enrolled providers who are eligible to appeal the denial of coverage and
    overpayment notices for the use of StimLabs’ products. In fact, APC has filed an appeal and it
    remains pending in the administrative process. Pls.’ Mot., Pls.’ Ex. 3, ECF No. 6-4 [hereinafter
    Dooley Decl.], ¶¶ 6, 8. APC and Wound Institute therefore cannot establish that they are
    completely precluded from administrative review.
    Plaintiffs’ jurisdictional hopes thus rest on StimLabs. They contend that “StimLabs falls
    squarely within the exception to the ‘channeling’ requirement’” because “StimLabs is not a
    provider and as such is an affected party that has no avenue for administrative review.” Pls.’ Reply
    at 11. Plaintiffs continue, “StimLabs is not required to, nor is it acting as the assignee of a Medicare
    beneficiary or supplier” and “the resulting decision would only apply to that individual claim and
    would not result in a global resolution.” 
    Id.
     Plaintiffs emphasize that they are challenging “the
    validity of the Policies and actions, not any present or past individual claim for Medicare
    reimbursement,” and that “the relief Plaintiffs seek is entirely procedural because their goal is to
    ensure that any consideration of their claims will be conducted only under valid regulations and
    that any reopenings comply with existing regulations.” Pls. Mem. at 19; Pls. Reply at 14.
    But the fact that, as a non-provider, StimLabs is unable to assert a claim directly, is
    challenging a policy and not an individual claim, and is seeking only procedural relief does not
    excuse it from the channeling requirement. To meet the Illinois Council exception, StimLabs still
    must show that there is not an “adequate proxy” that could raise claims on its behalf. Council for
    9
    Urological Ints., 668 F.3d at 712. It has not done so. Providers of StimLabs’ products, such as
    co-Plaintiffs APC and Wound Institute, are more than adequate proxies. Such providers have an
    obvious incentive to present claims and exhaust administrative remedies: if they do not challenge
    the denial of coverage and overpayment notices, they will be required to repay large sums to CMS
    and will not be reimbursed for future use of the products. APC alone claims to have received over
    $200,000 in overpayment notices. Dooley Decl. ¶ 14. Moreover, these providers will not have to
    pursue administrative remedies on their own. StimLabs will offer a helping hand. According to
    StimLabs, it employs a Director of Reimbursement Support who is “responsible for filing appeals
    on StimLabs’ products including Ascent and Corplex P.” Pls.’ Mot., Pls.’ Ex. 10, ECF No. 6-11,
    ¶ 3. Thus, this is not a case where, because “the only entities able to invoke Medicare Act review
    are highly unlikely to do so, their unwillingness to pursue a Medicare Act claim poses a serious
    ‘practical roadblock’ to judicial review.” Council for Urological Ints., 668 F.3d at 712. The
    providers who use StimLabs’ products are an “adequate proxy” to present claims. See RICU LLC
    v. U.S. Dep’t of Health & Hum. Servs., 
    22 F.4th 1031
    , 1038–39 (D.C. Cir. 2022) (holding that the
    “client hospitals” of a telehealth medicine company were an adequate proxy to seek reimbursement
    for incurred physicians’ costs).
    Plaintiffs’ arguments to the contrary are unpersuasive. Citing Baxter Healthcare Corp. v.
    Weeks, Plaintiffs primarily contend that “StimLabs is not required to recruit parties to bring an
    administrative claim on its behalf.” Pls.’ Reply at 10 (citing Baxter Healthcare Corp. v. Weeks,
    
    643 F. Supp. 2d 111
    , 116 (D.D.C. 2018) (“[American Chiropractic Ass’n v. Leavitt, 
    431 F.3d 812
    (D.C. Cir. 2005)] does not require Baxter to recruit a physician or hospital to act as its proxy in an
    administrative process.”). Defendants respond that the language in Baxter is a “misstatement of
    the law[,] . . . misapplies D.C. Circuit precedent[,] and stands out as an aberration.” Defs.’ Reply
    10
    Mem. in Supp. of Mot. to Dismiss, ECF No. 24 [hereinafter Defs.’ Reply], at 6. The court agrees
    that Baxter does not withstand scrutiny.
    The D.C. Circuit’s recent decision in RICU illustrates why. In that case, the plaintiff was
    an inpatient telehealth company that specialized in remote critical care services and contracted
    with U.S.-trained intensive-care physicians who lived and worked abroad. 
    22 F.4th 1031
    , 1033
    (D.C. Cir. 2022). “[C]lient hospitals” paid the plaintiff for the services provided by these
    physicians. 
    Id. at 1033
    . CMS ruled that “Medicare could not reimburse any telehealth services
    furnished by medical providers outside the United States.” 
    Id. at 1034
    . Not itself a provider, the
    plaintiff attempted to establish jurisdiction to sue under the Medicare Act by invoking the Illinois
    Council exception, but the D.C. Circuit rejected the effort. 
    Id.
     at 1038–39. It held that the “client
    hospitals are adequate proxies to channel [the plaintiff’s] general claim that its services are eligible
    for Medicare reimbursement through a concrete claim for payment.” 
    Id. at 1039
    . In reaching this
    conclusion, the court considered whether the client hospitals’ interests aligned with the plaintiff’s,
    ultimately concluding that they did because “these [hospitals] want the Department [of Health and
    Human Services] to allow reimbursement so they can more readily maintain or even expand their
    contracts with [the plaintiff].” 
    Id.
    The same is true here. Plaintiff StimLabs’ interests directly align with the interests of
    providers such as APC and Wound Institute. A favorable coverage determination will relieve
    providers of overpayment obligations, thus promoting their financial health, and will secure future
    use of the products. Furthermore, even if the court were to follow Baxter’s reasoning, StimLabs
    has already “recruited” a provider that can “seek administrative review of its claims.” Baxter, 643
    F. Supp. 2d at 116 (cleaned up). APC has filed an administrative appeal, presumably with
    StimLabs’ help, Pls.’ Ex. 3 ¶¶ 6–10, and the court is given no reason to think Wound Institute
    11
    cannot do the same. Thus, the court need not speculate whether StimLabs could “recruit” a
    proxy—it already has done so.
    Plaintiffs’ reliance on the out-of-Circuit decision in Akebia Therapeutics v. Becerra also is
    misplaced. Pls.’ Reply 9–11; 
    548 F. Supp. 3d 274
     (D. Mass 2021). There, the plaintiff was a drug
    manufacturer who sought judicial review of a CMS decision eliminating coverage for its drug.
    Akebia, 548 F. Supp. 3d at 276. The court determined the Illinois Council exception applied
    because the plaintiff was “not an association whose members could challenge CMS’s decision
    administratively,” was part of a “category of entities” (drug manufacturers) that are “wholly
    excluded from the Part D administrative review process,” and there was nothing to suggest the
    plaintiff “could act as a Part D participant’s assignee or appointed representative.” Id. at 286–87.
    The court further reasoned that the exception applied because “an individual Part D participant can
    challenge only an individual coverage determination . . . not a generally-applicable decision by the
    Government.” Id. at 297. But Akebia does not move the dial because it rejects the very D.C.
    Circuit precedent to which this court is bound. The court in Akebia described Council for
    Urological Interests as an “outlier and generally at odds with the trend in the case law that the
    applicability of the ‘no review’ exception depends on whether there is something the plaintiff can
    do to facilitate administrative review.” Id. at 286 n.14 (observing that “under the logic of Council
    for Urological Interests, the fact that Akebia cannot bring about administrative review could be
    considered unimportant because Part D participants are incentivized to do so (and have)”). This
    court, of course, is not free to dismiss Council for Urological Interests as an “outlier.”
    In short, because providers of StimLabs’ products are an adequate proxy to channel
    StimLabs’ general claim that its products are eligible for Medicare coverage, the Illinois Council
    exception does not apply, and thus the court lacks federal question jurisdiction over this action.
    12
    B.      Medicare Act Jurisdiction: 
    42 U.S.C. § 405
    (g)
    Alternatively, Plaintiffs contend that they have met the jurisdictional requirements of
    
    42 U.S.C. § 405
    (g). Pls.’ Reply at 12–16. According to Plaintiffs, they both presented their claims
    to the agency and qualify for waiver of the exhaustion requirement because the challenges they
    have raised are “collateral to the claims for benefits.” 
    Id.
     at 12–13 (quoting Bowen v. City of New
    York, 
    476 U.S. 467
    , 483 (1986)). Specifically, Plaintiffs assert that “the ‘exhaustion’ requirement
    should be waived because the Plaintiffs’ arguments are ‘entirely collateral’ to any claims that could
    be raised in an administrative proceeding because those proceedings are limited to reviews of
    individual claims and cannot make a determination that the Secretary failed to comply with
    Section 1395hh(a)(2) or the limits on reopenings of Medicare claims.” Id. at 14.
    Section 405(g) creates two prerequisites for judicial review: (1) “a plaintiff’s claim must
    have been presented to the Secretary,” and (2) “a plaintiff must fully exhaust the administrative
    remedies prescribed by the Secretary.” RICU, 22 F.4th at 1036 (quoting Mathews v. Eldridge, 
    424 U.S. 319
    , 328 (1976)) (cleaned up). The presentment requirement is a “nonwaivable element” of
    jurisdiction. Mathews, 
    424 U.S. at 328
    ; RICU, 22 F.4th at 1036 (“Section[] 405(g) . . . effectively
    preclude[s] the exercise of district court jurisdiction in the absence of presentment of a concrete
    dispute, regardless of the nature of the claim at issue.”). Exhaustion is waivable, and “[w]aiver is
    warranted if the claim is (1) collateral to a substantive claim of entitlement (collaterality);
    (2) colorable in its showing that denial of relief will cause irreparable harm (irreparability);
    and (3) one whose resolution would not serve the purposes of exhaustion (futility).” Sensory
    Neurostimulation, 977 F.3d at 981 (internal quotation marks omitted); see also Bowen, 
    476 U.S. at 483
     (stating that courts can waive § 405(g)’s exhaustion requirement where the claim is “entirely
    13
    collateral to [a] substantive claim of entitlement” and “the claim rest[s] ‘on the proposition that
    full relief cannot be obtained at a postdeprivation hearing’”) (quoting Mathews, 
    424 U.S. at 331
    ).
    At the outset, the court concludes that StimLabs has not met the presentment requirement.
    Plaintiffs insist that StimLabs presented a claim because its representatives “repeatedly contacted
    multiple agencies, including a MAC, CMS, and the FDA in order to explain” its position on
    coverage. Pls.’ Reply at 14 (citing Pls.’ Mot., Pls.’ Ex. 2, ECF No. 6-3, ¶ 9 (StimLabs provided
    coverage criteria to a MAC); 
    id.
     ¶¶ 13–14 (StimLabs expressed “concerns” to CMS through emails
    and phone calls about a MAC’s auditing and denial of Ascent claims); 
    id.
     ¶¶ 20–22 (StimLabs
    advised a MAC that clinical trials were not required for its products); Pls.’ Mot., Pls.’ Ex. 6, ECF
    No. 6-7, ¶¶ 2–3 (describing two telephone communications between counsel for StimLabs and
    representatives of CMS and FDA)). But that is not correct. “Presentment instead demand[s] that
    the Department have ‘an opportunity to rule on a concrete claim for reimbursement.’” RICU, 22
    F.4th at 1036 (quoting Heckler v. Ringer, 
    466 U.S. 602
    , 622 (1984)). Merely raising concerns
    generally about coverage decisions outside of the administrative process for a specific claim, as
    StimLabs did here, is not sufficient. See id. at 1037 (holding that mere request for guidance on
    how to apply an interim rule did not satisfy the presentment requirement).
    Unlike StimLabs, APC is challenging through the Medicare administrative appeals process
    specific adverse decisions with respect to its use of Ascent. Dooley Decl. ¶¶ 6–8 (stating that APC
    has “appealed through the Redetermination phase of the Medicare appeals process” and has further
    appealed to “the qualified independent contractor responsible for the appeal of [the MAC’s]
    decision”). Still, Plaintiffs have not shown that APC has met the presentment requirement.
    “[A]ll aspects” of a claim must be channeled. Heckler, 
    466 U.S. at 614
    . That means a claimant
    cannot bring a challenge in federal court that it has not raised before the agency. See Am. Hosp.
    14
    Ass’n v. Azar, 
    895 F.3d 822
    , 826 (D.C. Cir. 2018) (holding that the plaintiffs had not satisfied the
    presentment requirement where none of them “had challenged the new reimbursement regulation
    in the context of a specific administrative claim for payment”). Plaintiffs have put neither APC’s
    appeal nor the MAC’s determination letter before the court, so the court cannot say for sure on
    what grounds APC contested the overpayment notice. APC’s declarant has described the basis for
    the MAC’s adverse ruling, but that summary makes it seem that APC’s claim was denied because
    the MAC deemed the use of Ascent not to be “reasonable and necessary.” Dooley Decl. ¶ 7 (noting
    that the MAC’s decision rested in part on Ascent being “experimental/investigational”). Thus,
    when Plaintiffs filed this suit, none of them appear to have challenged CMS’s purported unwritten
    policy on the grounds advanced here “in the context of a specific administrative claim for
    payment.” Am. Hosp. Ass’n, 895 F.3d at 826. Accordingly, the court finds that Plaintiffs have
    failed to meet the “presentment” requirement under § 405(g).
    Waiver of the exhaustion requirement also would not be appropriate. Plaintiffs’ challenge
    here is not “collateral to the claims for benefits.” Bowen, 
    476 U.S. at 483
    . It is directly related to
    the reasons for the denials themselves. According to Plaintiffs, Medicare’s policy of covering only
    approved FDA drug products does not apply to HCT/Ps because they “are not regulated as drugs”
    and thus do “not require prior FDA approval.” Compl. ¶¶ 20, 42 (“These HCT/Ps are not regulated
    as drugs, biologics, or medical devices and no premarket submissions are required for FDA review
    or approval.”). Yet, they allege, since the rescission of the TDLs, MACs have continued to reopen
    and wrongly deny coverage for their products, often “on the same rationale articulated in the TDLs,
    asserting that the claims can be denied because neither Ascent nor Corplex P has received
    premarket approval from the FDA, even though FDA approval is not required for HCT/P
    products.” Id. ¶ 63 (emphasis added). Thus, Plaintiffs’ complaint, at bottom, seems to be that
    15
    CMS’s “unwritten policy” of denying coverage for Ascent and Corplex P is based on a basic
    misunderstanding of their products, see id. ¶ 59 (asserting that StimLabs’ products are not exosome
    products that were the subject of the FDA’s December 2019 Public Safety Notification), and a
    mistaken application of its own regulations, which do not require FDA approval for HCT/Ps, id.
    ¶ 20. Such challenges are not “collateral” to the benefits denials. See Bowen, 
    476 U.S. at 483
    .
    They are central to the benefits denials themselves.
    Additionally, waiver of the exhaustion requirement is unwarranted because no Plaintiff has
    plausibly established that it would be irreparably harmed if it were required to channel its claims.
    Plaintiffs maintain that, “[o]n information and belief, StimLabs estimates that a loss of Medicare
    coverage for Corplex P alone will result in a loss of approximately 20% of its current revenue that
    cannot be compensated through damages.” Compl. ¶ 65; Pls. Mot., Ex. 4, ECF No. 6-5 [hereinafter
    Steele Decl.] ¶ 13. But it is settled in this Circuit that “[r]ecoverable monetary loss may constitute
    irreparable harm only where the loss threatens the very existence of the movant’s business.” Wis.
    Gas Co. v. FERC, 
    758 F.2d 669
    , 674 (D.C. Cir. 1985). 1 StimLabs’ claimed revenue loss does not
    meet that stringent standard. APC also contends that it has received approximately $200,000 in
    overpayment demands, “which if fully recouped could result in the shuttering of [the] practice.”
    Dooley Decl. ¶ 14 (emphasis added). That recoupment “could result” in business harm is too thin
    a reed on which to plausibly establish irreparable harm.
    1
    StimLabs also asserts that the downstream effects of CMS’s actions will cause “approximately $23 Million in losses
    associated with the discontinuation of Corplex P products this year alone,” which along with potential repayments to
    customers, threatens StimLabs’ “ability to continue as a going concern.” Steele Decl. ¶¶ 15–16. But this magnitude
    of losses appears speculative. StimLabs does not, for example, explain what percentage of its providers depend on
    Medicare for reimbursement, such that they are likely to discontinue using its products. Moreover, to the extent that
    CMS’s denial of coverage has resulted in providers demanding refunds, that would appear to be a consequence of
    StimLabs’ apparent business decision to indemnify its customers in the event of coverage denials, not any agency
    action.

    C.      Mandamus Act Jurisdiction: 
    28 U.S.C. § 1361
    Plaintiffs also invoke the court’s jurisdiction pursuant to the Mandamus Act, 
    28 U.S.C. § 1361
    . The D.C. Circuit has held that mandamus jurisdiction is not precluded by § 405(h).
    Monmouth Med. Ctr. v. 
    Thompson, 257
     F.3d 807, 813 (D.C. Cir. 2001). Such relief is available
    in the Medicare Act context, however, only “to review otherwise unreviewable procedural issues”
    that are “unrelated to the merits.” Randall D. Wolcott, M.D., P.A. v. Sebelius, 
    635 F.3d 757
    , 765–
    66 (5th Cir. 2011). As discussed already, Plaintiffs’ procedural claims here are not unrelated to
    the merits; on the contrary, they rest on Plaintiffs’ merits contention that CMS in fact has changed
    its coverage policy. For that reason alone, the exercise of mandamus jurisdiction is not appropriate.
    Additionally, mandamus relief is available only if: “(1) the plaintiff has a clear right to
    relief; (2) the defendant has a clear duty to act; and (3) there is no other adequate remedy available
    to the plaintiff.” Council of & for the Blind of Del. Cnty. Valley, Inc. v. Regan, 
    709 F.2d 1521
    ,
    1533 (D.C. Cir. 1983). Even if all jurisdictional requirements are met, “a court may grant relief
    only when it finds compelling equitable grounds.” Am. Hosp. Ass’n v. Burwell, 
    812 F.3d 183
    , 189
    (D.C. Cir. 2016) (internal quotation marks omitted). “The party seeking mandamus has the burden
    of showing that its right to issuance of the writ is clear and indisputable.” 
    Id.
     (internal quotation
    marks omitted).
    Here, Plaintiffs have not met their burden. For starters, Plaintiffs have not shown that the
    administrative appeals process is not an adequate remedy.           This by itself bars mandamus
    jurisdiction. See Monmouth, 257 F.3d at 810 (“[W]e must first examine all other possible avenues
    of relief to ensure that the hospitals have fully exhausted those which were available.”); id. at 813
    (stating that mandamus is available only when the claimant has exhausted administrative
    remedies).
    17
    Moreover, mandamus relief is unavailable because there is no clear, “ministerial” duty to
    act. Plaintiffs argue that “the Secretary has a clear duty to inform the MACs that they may no
    longer follow the policy in question and to instruct them to stop engaging the reopening of claims
    on grounds that are prohibited by statute.” Pls.’ Reply at 19. Similar mandamus requests have
    been rejected by district courts in this Circuit. For example, in California Clinical, the plaintiff
    sought “[a]n order mandating the Secretary and her agents, including MACs, to comply with all
    applicable provisions of the Constitution and the Medicare Act,” similarly over a dispute regarding
    the Secretary’s alleged failure to engage in notice-and-comment rulemaking. 104 F. Supp. 3d at
    83–84. Then-Judge Ketanji Brown Jackson rejected mandamus jurisdiction, because the plaintiff
    had “neither demonstrated that it has any clear right to an order requiring the Secretary to comply
    with these procedural mandates, nor has it shown that the Secretary has any clear, nondiscretionary
    duty to act under the provisions at issue.” Id. at 84. The same is true here.
    Simply put, Plaintiffs have not plausibly established that this is the type of “extraordinary
    case” in which the “drastic remedy” of mandamus would be proper. Id. at 83.
    IV.    CONCLUSION
    For the foregoing reasons, Defendants’ Motion to Dismiss, ECF No. 17, is granted, and
    Plaintiffs’ Motion for Preliminary Injunction, ECF No. 6, is denied. A separate, final order
    accompanies this Memorandum Opinion.
