    MEMORANDUM OPINION
    Pending before the Court are cross-motions for summary judgment from the plaintiffs,
    several hospitals that offer inpatient and outpatient hospital services to patients entitled to
    benefits under the Medicare program, Pls.’ Mot. Summ. J. (“Pls.’ Mot.”), ECF No. 15, and the
    defendant, the Secretary of Health and Human Services (“HHS”), who is sued in his official
    capacity, Def.’s Cross-Mot. Summ. J. (“Def.’s Mot.”), ECF No. 17. 1 The plaintiffs seek judicial
    review of a final adverse agency decision by HHS and the vacatur of a 2005 final rule that
    allegedly reduced the payments that the plaintiffs should have received from HHS to compensate
    them for the disproportionate number of low-income patients served in their hospitals. See Pls.’
    Mot. at 1. The plaintiffs allege that the final rule at issue violates the Administrative Procedure
    Act (“APA”), 5 U.S.C. § 706, because the rule is procedurally defective and arbitrary and
    capricious. See Compl. ¶¶ 81–88, ECF No. 1; Pls.’ Mem. Supp. Mot. Summ. J. (“Pls.’ Mem.”)
    at 2, ECF No. 15-1. The defendant counters that the final rule was a logical outgrowth of the
    proposed rule and that the adoption of the rule was the result of a reasoned deliberative process.
    See Def.’s Mem. Supp. Cross-Mot. Summ. J. & Opp’n Pls.’ Mot. Summ. J. (“Def.’s Mem.”) at 1,
    ECF No. 17-1. For the reasons set forth below, the plaintiffs’ motions are denied and the
    defendant’s motions are granted.
    I.      BACKGROUND
    Resolving the instant motions requires examining the “labyrinthine world of Medicare
    reimbursements.” Dist. Hosp. Partners, L.P. v. Burwell,

    Also pending before the Court are cross-motions for summary judgment filed in a consolidated case, which
    motions are identical to the cross-motions filed in the above-captioned case. See W. Anaheim Pls.’ Mot. Summ. J.,
    ECF No. 23; Def.’s W. Anaheim Cross-Mot. Summ. J., ECF No. 21. For ease of reference, all citations refer to the

    (internal quotation marks omitted). The relevant portions of the Medicare statute are explained
    first, followed by the rulemaking challenged by the plaintiffs.
    A.       Statutory Framework
    Medicare is a federal program that pays for health-care services furnished to eligible
    beneficiaries, who are generally individuals over the age of sixty-five or individuals with
    disabilities. See 42 U.S.C. § 1395c. The Centers for Medicare and Medicaid Services (“CMS”)
    is the component of HHS that administers the Medicare program. See St. Elizabeth’s Med. Ctr.
    of Bos., Inc. v. Thompson, 
    396 F.3d 1228
    , 1230 (D.C. Cir. 2005). CMS reimburses health-care
    providers for, inter alia, “the reasonable cost” of services provided to Medicare beneficiaries.
    See 42 U.S.C. § 1395f(b)(1). 2
    The Medicare statute has five parts, two of which are relevant to this case. Part A
    “establishes the requirements that individuals must meet to be eligible for Medicare benefits and
    provides such individuals insurance for hospital and hospital-related services.” Catholic Health
    Initiatives Iowa Corp. v. Sebelius, 
    718 F.3d 914
    , 916 (D.C. Cir. 2013) (citing 42 U.S.C.
    § 1395c). Such benefits include coverage for “inpatient hospital services,” including overnight
    stays in a hospital. 42 U.S.C. § 1395d. Part A benefits are limited to a certain number of days,
    however, and after those days have been used, Part A coverage is “exhausted.” Catholic 
    Health, 718 F.3d at 916
    . “Specifically, Medicare beneficiaries are entitled to coverage for the first 90
    days of their stay, and they may then elect to use up to 60 ‘lifetime reserve days’ beyond the first
    90 days.” 
    Id. (quoting 42
    C.F.R. § 409.61(a)); see also 42 U.S.C. § 1395d.
    2
    “Provider of services” is defined as “a hospital, critical access hospital, skilled nursing facility,
    comprehensive outpatient rehabilitation facility, home health care agency, hospice program, or, for purposes of
    [other provisions] of this title, a fund.” 42 U.S.C. § 1395x(u).
    3
    Part E, which sets out “Miscellaneous Provisions,” works in tandem with Part A to
    provide a “prospective payment system for reimbursing hospitals that provide inpatient hospital
    services covered under Part A.” Catholic 
    Health, 718 F.3d at 916
    (citing 42 U.S.C. § 1395ww(d)).
    As relevant to this case, Part E mandates that any hospital serving “a significantly disproportionate
    number of low-income patients” is entitled to a payment adjustment, known as the “disproportionate
    share hospital” (“DSH”) adjustment, which is an upward adjustment to a hospital’s reimbursement
    amount to account for the hospital’s treatment of a disproportionately high number of low-
    income patients. 42 U.S.C. § 1395ww(d)(5)(F)(i)(I); see also 
    id. § 1395ww(d)(2);
    Pls.’ Mem. at 4
    (“The DSH adjustment is an upward adjustment to standard rates to compensate hospitals for the
    generally higher per-patient costs of low-income patients.”). As the D.C. Circuit has recognized,
    the DSH adjustment “is based on Congress’s judgment that low-income patients are often in
    poorer health, and therefore costlier for hospitals to treat.” Catholic 
    Health, 718 F.3d at 916
    (citing Adena Reg’l Med. Ctr. v. Leavitt, 
    527 F.3d 176
    , 177–78 (D.C. Cir. 2008)).
    A hospital’s DSH adjustment is based on its “disproportionate patient percentage”
    (“DPP”). 42 U.S.C. § 1395ww(d)(5)(F)(v). To qualify for a DSH adjustment, a hospital’s DPP
    typically must exceed 15 percent, although the qualifying percentage varies depending on the
    size of the hospital and whether it is located in an urban or a rural area. See 
    id. Generally, “a
    higher DPP means greater reimbursements because the hospital is serving more low-income
    patients.” Catholic 
    Health, 718 F.3d at 916
    . The DPP is a “‘proxy measure’ for the number of
    low-income patients a hospital serves and represents the sum of two fractions, commonly called
    the ‘Medicare fraction’ and the ‘Medicaid fraction.’” Ne. Hosp. Corp. v. Sebelius, 
    657 F.3d 1
    , 3
    (D.C. Cir. 2011) (internal citation omitted) (quoting H.R. REP. NO. 99-241, pt. 1, at 17 (1985)).
    The Medicare fraction is statutorily defined as:
    4
    [T]he fraction (expressed as a percentage), the numerator of which is the number of such
    hospital’s patient days for such period which were made up of patients who (for such
    days) were entitled to benefits under [Medicare] part A . . . and were entitled to
    supplementary security income [(“SSI”)] benefits . . . , and the denominator of which is
    the number of such hospital’s patient days for such fiscal year which were made up of
    patients who (for such days) were entitled to benefits under [Medicare] part A.
    42 U.S.C. § 1395ww(d)(5)(F)(vi)(I). The Medicaid fraction is defined as:
    [T]he fraction (expressed as a percentage), the numerator of which is the number of the
    hospital’s patient days for such period which consist of patients who (for such days) were
    eligible for medical assistance under a State [Medicaid] plan . . . but who were not
    entitled to benefits under [Medicare] part A . . . , and the denominator of which is the
    total number of the hospital’s patient days for such period.
    
    Id. § 1395ww(d)(5)(F)(vi)(II).
    As the D.C. Circuit has noted, “[t]his language is downright byzantine and its meaning
    not easily discernible.” Catholic 
    Health, 718 F.3d at 917
    . In essence, “[t]he Medicare and
    Medicaid fractions represent two distinct and separate measures of low income—SSI (i.e.,
    welfare) and Medicaid, respectively—that when summed together, provide a proxy for the total
    low-income patient percentage.” 
    Id. The D.C.
    Circuit has often used the following visual
    representation to distill these formulas:
    Medicare Fraction                        Medicaid Fraction
    Numerator         Patient days for patients “entitled to   Patient days for patients “eligible for
    benefits under part A” and “entitled     [Medicaid]” but not “entitled to
    to SSI benefits”                         benefits under part A”
    Denominator       Patient days for patients “entitled to   Total number of patient days
    benefits under part A”
    Id.; see also Ne. 
    Hosp., 657 F.3d at 3
    . The denominator of the Medicaid fraction—total number
    of patient days—is larger than the denominator of the Medicare fraction, which contains only
    patient days for those patients “entitled to benefits under part A.” Thus, shifting patient days
    from the numerator of the Medicaid fraction to the numerator of the Medicare fraction will
    generally have a larger impact on a hospital’s DPP and, accordingly, on its DSH adjustment.
    5
    A “fiscal intermediary,” such as a private insurance company that has a contract with
    CMS, is responsible for “[d]etermining the amount of payments to be made to providers for
    covered services furnished to Medicare beneficiaries” and then “[m]aking the payments” to the
    hospitals. 42 C.F.R. § 421.100(a)(1)–(2); see also 
    id. § 421.3.
    If a hospital providing covered
    services “is dissatisfied with a final determination of the organization serving as its fiscal
    intermediary” regarding “the amount of total program reimbursement due the provider,” the
    hospital “may obtain a hearing with respect to such [determination] by a Provider Reimbursement
    Review Board” (“PRRB”). 42 U.S.C. § 1395oo(a)(1)(A)(i). To obtain such review, the hospital
    must “file[ ] a request for a hearing with 180 days after notice of the intermediary’s final
    determination.” 
    Id. § 1395oo(a)(3).
    The PRRB may then “affirm, modify, or reverse a final
    determination of the fiscal intermediary.” 
    Id. § 1395oo(d);
    see also Ne. 
    Hosp., 657 F.3d at 3
    –4.
    PRRB decisions “shall be final unless the Secretary, on his own motion, and within 60
    days after the provider of services is notified of the [PRRB’s] decision, reverses, affirms, or
    modifies” the PRRB’s decision. 42 U.S.C. §1395oo(f)(1). Notably, however, the PRRB lacks
    the authority to declare statutes, regulations, or rules invalid. See Bethesda Hosp. Ass’n v.
    Bowen, 
    485 U.S. 399
    , 406 & n.4 (1988) (citing 42 U.S.C. § 1395oo(d)); 42 C.F.R. § 405.1867
    (instructing that the PRRB “shall afford great weight to interpretive rules, general statements of
    policy, and rules of agency organization, procedure, or practice established by CMS”). Thus,
    when a hospital seeks to challenge the validity of a rule or regulation, the challenger must first
    obtain a determination by the PRRB, either on a petition or sua sponte, that the PRRB “lacks the
    authority to decide the legal question.” 42 C.F.R. § 405.1842(a)(1) (citing 42 C.F.R. § 405.1867).
    The hospital may then “request a [PRRB] decision that the provider is entitled to seek” expedited
    judicial review (“EJR”) of the issue. 
    Id. § 405.1842(a)(2).
    If the PRRB grants EJR, “the
    6
    provider may file a complaint in Federal district court in order to obtain EJR of the legal
    question.” 
    Id. §405.1842(g)(2). B.
         Rulemaking History Leading to the 2005 Final Rule
    At issue in this lawsuit is the treatment of patient days in the Medicare fraction or the
    Medicaid fraction for individuals who were eligible for both programs—“dual eligible”
    individuals—but for whom Medicare did not pay for care, either because the patient had
    exhausted his or her Part A benefits for that period of hospitalization or because an entity other
    than the Medicare Trust Fund paid for that care. See Pls.’ Mem. at 1; Def.’s Mem. at 4.
    Specifically, this dispute centers on whether such “dual-eligible exhausted days” should be
    counted in the Medicare fraction or instead in the Medicaid fraction. If dual-eligible exhausted
    days were included in the Medicare fraction, they would be added to the denominator of the
    Medicaid fraction and, if the patient had been entitled to SSI benefits, also to the numerator. If
    dual-eligible exhausted days were included in the Medicaid fraction, they would be added to the
    numerator of the Medicaid fraction. The denominator of the Medicaid fraction is not at issue,
    because that value includes all patient days regardless of eligibility or exhaustion.
    This distinction matters, because the denominator of the Medicaid fraction (total patient
    days) is greater than the denominator of the Medicare fraction (patient days for patients “entitled
    to benefits under part A”). Thus, including dual-eligible exhausted days in the Medicare fraction
    denominator (and, when appropriate, numerator) rather than in the Medicaid fraction numerator
    will often tend to give those days more of an impact on a hospital’s DPP and, correspondingly,
    on its DSH adjustment. The relevant rulemaking history is described next.
    1.      2004 Proposed Rule
    In 2003, the Secretary issued a proposed rule for the 2004 fiscal year outlining “proposed
    changes to the hospital inpatient prospective payment systems and fiscal year 2004 rates” for the
    7
    Medicare program. Medicare Program; Proposed Changes to the Hospital Inpatient Prospective
    Payment Systems and Fiscal Year 2004 Rates (“2004 Proposed Rule”), 68 Fed. Reg. 27,154,
    27,154 (May 19, 2003) (capitalization omitted). As it relates to this lawsuit, the Secretary
    proposed to revise the manner in which dual-eligible exhausted patient days are counted in the
    Medicare and Medicaid fractions. The 2004 Proposed Rule explained that currently, “[i]f a
    patient is a Medicare beneficiary who is also eligible for Medicaid, the patient is considered
    dual-eligible and the patient days are included in the Medicare fraction of the DSH patient
    percentage but not the Medicaid fraction.” 
    Id. at 27,207.
    Importantly, the 2004 Proposed Rule
    emphasized that:
    This policy currently applies even after the patient’s Medicare coverage is exhausted. In
    other words, if a dual-eligible patient is admitted without any Medicare Part A coverage
    remaining, or exhausts Medicare Part A coverage while an inpatient, his or her patient
    days are counted in the Medicare fraction before and after Medicare coverage is
    exhausted. This is consistent with our inclusion of Medicaid patient days even after the
    patient’s Medicaid coverage is exhausted.
    
    Id. That is,
    under the stated status quo, dual-eligible days were to be counted in the denominator
    of the Medicare fraction (and, if the patient were entitled to SSI benefits, also in the numerator of
    the Medicare fraction), regardless of whether the patient had exhausted his or her available
    Medicare Part A coverage. The Secretary then explained that he was contemplating a change in
    the way dual-eligible exhausted days would be counted:
    We are proposing to change our policy, to begin to count in the Medicaid fraction of the
    DSH patient percentage the patient days of dual-eligible Medicare beneficiaries whose
    Medicare coverage has expired. . . . As noted above, our current policy regarding dual-
    eligible patient days is that they are counted in the Medicare fraction and excluded from
    the Medicaid fraction, even if the patient’s Medicare Part A coverage has been exhausted.
    . . . [I]n order to facilitate consistent handling of these days across all hospitals, we are
    proposing that the days of patients who have exhausted their Medicare Part A coverage
    will no longer be included in the Medicare fraction. Instead, we are proposing these days
    should be included in the Medicaid fraction of the DSH calculation.
    8
    
    Id. at 27,207–08.
    In other words, the Secretary proposed adopting the opposite of the stated
    current policy: rather than continue to count dual-eligible days, regardless of whether Part A
    coverage had been exhausted, in the appropriate parts of the Medicare fraction, the Secretary
    proposed to begin counting only dual-eligible unexhausted days in the Medicare fraction while
    counting dual-eligible exhausted days in the Medicaid fraction.
    2.      Initial Comment Period for the 2004 Proposed Rule
    The comment period on the 2004 Proposed Rule remained open through July 18, 2003.
    
    Id. at 27,154.
    Many commenters supported the policy that the Secretary had described as the
    existing policy—namely, the inclusion of dual-eligible days in the denominator (and, when
    entitled to SSI benefits, also in the numerator) of the Medicare fraction, regardless of whether the
    patient’s Part A coverage had been exhausted—and opposed the proposed change to begin
    including dual-eligible exhausted days in the numerator of the Medicaid fraction. As discussed
    below, this is the policy that the Secretary ultimately adopted in the 2005 Final Rule. The
    American Hospital Association (“AHA”) opposed the proposed change because “CMS
    provide[d] no justified reason for making this change, and there are clear reasons not to make this
    change.” Administrative Record (“AR”) at 754R, ECF No. 30-1 (emphasis in original). The AHA
    noted that “CMS clearly states in the proposed rule that the current formula is consistent with
    statutory intent” and that “the proposed change would place a significant new regulatory and
    administrative burden on hospitals.” 
    Id. In addition,
    the AHA explained that “it is likely that
    this proposed change would result in reduced DSH payments to hospitals” because “[a]ny
    transfer of a particular patient day from the Medicare fraction (based on total Medicare patient
    days) to the Medicaid fraction (based on total patient days) will dilute the value of that day, and
    therefore reduce the overall patient percentage and the resulting DSH adjustment. Thus the
    9
    calculation of dual-eligible days must not be changed.” 
    Id. at 754–55R
    (emphasis in original).
    Other commenters likewise emphasized that the stated current policy was consistent with
    statutory intent and that the change would result in large administrative burdens for hospitals.
    See, e.g., 
    id. at 486R
    (comments of Association of American Medical Colleges that “current
    policy is consistent with statutory intent” and that proposed policy will impose a “new
    administrative burden . . . on hospitals to provide documentation”); 
    id. at 583R
    (comments of
    Healthcare Association of New York State that “it will be difficult for hospitals to provide the
    data required under this proposal”); 
    id. at 718R
    (comments of University of Pittsburgh Medical
    Center Health System opposing the proposal “due to the additional workload that will be applied
    to the providers’ limited resources”); 
    id. at 816R
    (comments of National Association of Public
    Hospitals and Health Systems noting the “significant new regulatory and administrative burden
    on hospitals” imposed by proposed rule).
    Other commenters emphasized the likelihood that DSH payments would decrease under
    the proposed rule. For example, the National Association of Public Hospitals and Health
    Systems noted that the proposed rule would “have the effect of reducing DSH payments across-
    the-board” because “the transfer of any particular patient day from the Medicare to the Medicaid
    fraction will always dilute the value of that day and therefore reduce the overall patient percentage
    and the resulting DSH adjustment.” 
    Id. at 816R;
    see also 
    id. at 683R
    (comments of Mercy Hospital
    that “[t]he result will be a loss ranging from approximately ($500,000) to ($800,000) for each
    1,000 days adjusted based on a varied Medicaid eligibility percentage from 100% to 0%”); 
    id. at 789R
    (comments of Federation of American Hospitals that “the proposed policy would result in
    a reduction of DSH payments when Exhausted Days are removed from the Medicare fraction”).
    10
    In addition, the Federation of American Hospitals alleged that “CMS lacks statutory
    authority to implement the proposed policy regarding Exhausted Days” because “Exhausted
    Days patients remain entitled to” certain Part A benefits even though they have “reached their
    coverage limit for inpatient hospital services.” 
    Id. at 789R.
    The Federation contended that,
    “[u]nder CMS’s proposed interpretation of the DSH statute, it is impossible to reconcile the
    position that these patients are not entitled to Medicare Part A when they can receive other Part
    A services, such as skilled nursing services,” 
    id. at 790R,
    and “strongly urge[d] CMS not to
    finalize this policy,” 
    id. Only one
    commenter, the BlueCross BlueShield Association, wrote in support of the
    proposed rule. BlueCross noted that it “agree[d] with the proposed change to include in the
    Medicaid percentage the patient days of dual eligible Medicare beneficiaries whose Medicare
    coverage has expired,” but the Association nevertheless recommended “eliminating the
    requirement that the hospital submit documentation to the fiscal intermediary that justifies
    including the days in the Medicaid fraction.” 
    Id. at 566R.
    Notably, two commenters wrote to express confusion about the Secretary’s statement of
    the existing policy. The law firm Vinson & Elkins wrote, on its own behalf, in support of the
    proposed rule but “disagree[d] . . . that CMS’ description of its past practice is correct.” 
    Id. at 860R.
    Specifically, Vinson & Elkins noted that the proposed rule was “at odds with the plain
    language of the regulation” governing the DSH adjustment, which stated that the Medicare
    fraction included “‘covered patient days’ only”—in other words, unexhausted days only. 
    Id. at 861R
    (quoting 42 C.F.R. § 412.106(b)(2)(i) (2003)). That is, the Secretary’s stated proposed rule
    was actually the manner in which dual-eligible exhausted days were currently being handled and
    the exact opposite of the policy the Secretary had put forth as the status quo. Vinson & Elkins
    11
    urged CMS to correct its misstatement, arguing that if the agency chose to stand by those
    statements, “it will squander its credibility with the courts and set[ ] itself up not only to lose as
    the issue is litigated but to subject itself to paying attorney fees and other sanctions.” 
    Id. Southwest Consulting
    Associates (“SCA”) also wrote to identify the misstatement, noting
    that “CMS’ statement ‘the days of patients who have exhausted their Medicare Part A coverage
    will no longer be included in the Medicare fraction’ is inconsistent with CMS’ current actual
    practice with respect to the Medicare fraction.” 
    Id. at 405R.
    SCA had obtained a letter from
    HHS’s Office of General Counsel, dated August 14, 2001, “stating that only covered days [that
    is, unexhausted days] are used in the [Medicare] fraction.” Id.; see also 
    id. at 363R
    (letter from
    Linda Banks, CMS, to Christopher Keough, noting that “the Medicare/SSI denominator includes
    only the covered days,” not exhausted days). Thus, SCA noted that “[t]o say that [exhausted]
    days ‘will no longer be included’” in the Medicare fraction “may be a change in ‘policy,’ but it is
    clearly not a change in ‘practice.’ That begs the question—What was the ‘policy’—what CMS
    professed or what it did?” 
    Id. at 405R.
    3.      2004 Final Rule
    On August 1, 2003, the Secretary issued a final rule for fiscal year 2004. Regarding the
    treatment of dual-eligible patient days, the Secretary noted that “[w]e are still reviewing the large
    number of comments received on the proposed provision relating to dual-eligible patient days in
    the May 19, 2003 [sic]. Due to the number and nature of the comments we received on our
    proposed policies, we are addressing the public comments in a separate document.” Medicare
    Program; Changes to the Hospital Inpatient Prospective Payment Systems and Fiscal Year 2004
    Rates (“2004 Final Rule”), 68 Fed. Reg. 45,346, 45,421 (Aug. 1, 2003). The 2004 Final Rule did
    12
    not reference or address the commenters’ concerns that the agency may have misstated its
    current policy by confusing its current practice with its proposed practice.
    4.      2005 Proposed Rule and Second Comment Period
    On May 18, 2004, the Secretary issued a proposed rule offering “changes to the hospital
    inpatient prospective payment systems [“IPPS”] and fiscal year 2005 rates.” Medicare Program;
    Proposed Changes to the Hospital Inpatient Prospective Payment Systems and Fiscal Year 2005
    Rates (“2005 Proposed Rule”), 69 Fed. Reg. 28,196, 28,196 (May 18, 2004) (capitalization
    omitted). As relevant to this case, the Secretary noted that “[i]n our May 19, 2003 IPPS proposed
    rule for FY 2004 (68 FR 27201), we proposed changes to our policy on counting available beds
    and patient days for the purposes of the DSH adjustment.” 
    Id. at 28,286.
    The Secretary
    explained that “[d]ue to the number and nature of the public comments received, we did not
    respond to the public comments on these proposals in the final rule for FY 2004 (68 FR 45415).”
    
    Id. Rather, the
    Secretary noted that the agency planned to address comments regarding the
    proposed new treatment of dual-eligible days “in the IPPS final rule for FY 2005.” 
    Id. The comment
    period for the 2005 Proposed Rule closed on July 12, 2004. 
    Id. at 28,196.
    The 2005
    Proposed Rule again did not mention any possible misstatement of the current handling of dual-
    eligible days or any confusion regarding the agency’s current policy and its proposed policy.
    Five days before the close of the comment period, on July 7, 2004, the Secretary
    acknowledged publicly in a notice posted on its website the fact that it had made precisely such a
    mistake. The Secretary explained:
    In the May 19, 2003 proposed rule (68 FR 27207) we indicated, with respect to dual-
    eligibles, that the policy described above currently applies even after the patient’s
    Medicare Part A coverage is exhausted. That is, we stated that if a dual-eligible patient is
    admitted without any Medicare Part A coverage remaining, or the patient exhausts
    Medicare Part A coverage while an inpatient, the non-covered patient days are counted in
    the Medicare fraction. It has come to our attention, however, that this statement is not
    13
    accurate. Our policy has been that only covered patient days are included in the
    Medicare fraction.
    AR at 340R. The Secretary provided no other explanation for the misstatement and did not extend
    the comment period for the 2005 Proposed Rule, which was scheduled to end on July 12, 2004.
    During the second comment period, many interested parties again wrote to the Secretary
    opposing the proposed rule and supporting what the Secretary had described as the status quo—
    which is the policy ultimately adopted in the 2005 Final Rule. On July 2, 2004, the AHA
    submitted comments identical to its previous letter, arguing that the current formula is “consistent
    with statutory intent,” that “the proposed change would place a significant new regulatory and
    administrative burden on hospitals, and that “this proposed change would result in reduced DSH
    payments to hospitals.” 
    Id. at 428R.
    In the days following the Secretary’s July 7, 2004, website
    posting, numerous other commenters submitted letters identical to the AHA’s comments
    opposing the proposed rule. See, e.g., 
    id. at 30–31R
    (comments of California Healthcare
    Association dated July 12, 2004); 
    id. at 130R
    (comments of New Jersey Hospital Association
    dated July 12, 2004); 
    id. at 152R
    (comments of Catholic Healthcare West dated July 9, 2004); 
    id. at 184R
    (comments of Michigan Health & Hospital Association dated July 9, 2004); 
    id. at 193R
    (comments of Missouri Hospital Association dated July 9, 2004); 
    id. at 254–55R
    (comments of
    Lincoln General Hospital dated July 8, 2004); 
    id. at 267R
    (comments of Louisiana Hospital
    Association dated July 8, 2004); 
    id. at 304R
    (comments of Ochsner Clinic Foundation dated July
    8, 2004); 
    id. at 323R
    (comments of Tennessee Hospital Association dated July 8, 2004); 
    id. at 335R
    (comments of Touro Infirmary dated July 8, 2004); 
    id. at 410R
    (comments of West
    Virginia Hospital Association dated July 7, 2004).
    Still other commenters argued that the proposed rule “runs counter to the law and is
    otherwise inequitable to hospitals receiving DSH funding,” 
    id. at 297R
    (comments of Oakwood
    14
    Healthcare System dated July 8, 2004); that “[t]his change would require additional recordkeeping
    on the part of hospitals,” 
    id. at 163R
    (comments of Illinois Hospital Association dated July 9,
    2004); and that “shifting the burden of proof to the providers and intermediaries will only make
    the task of determining eligible days more burdensome and costly to the facility,” 
    id. at 171R
    (comments of Jewish Hospital Healthcare Services dated July 9, 2004).
    Notably, only one commenter mentioned the Secretary’s website posting in its comments.
    The Federation of American Hospitals (“FAH”), which had written in opposition to the proposed
    rule during the first comment period, wrote to discuss the misstatement. FAH explained that,
    “[w]hen drafting its comments for FY 2004, FAH took at face value CMS’s statement that,
    historically, Part A Exhausted/Noncovered Days have been included in the Medicare fraction.”
    
    Id. at 81R.
    Thus, “[a]ssuming that this was true, and concerned that, if moved to the Medicaid
    fraction, the burden would be on the provider to identify these days, which might result in a
    lower number of days counted, FAH argued for a continuation of the existing policy to include
    these days in the Medicare percentage.” 
    Id. Since submitting
    its comments, however, “FAH
    ha[d] been informed that at least one knowledgeable fiscal intermediary, and possibly members
    of CMS staff, have indicated that further research has confirmed that such days are, in fact, not
    currently (and never were) included in the Medicare percentage.” 
    Id. at 82R.
    FAH thus urged
    the Secretary to “continue to accept comments on this issue.” 
    Id. at 81R.
    In addition, FAH
    argued that dual-eligible exhausted days should be included in the Medicare fraction, but that
    “[i]f such days are not counted in the Medicare fraction, then the days must be counted in the
    Medicaid fraction.” 
    Id. at 82R.
    15
    5.      2005 Final Rule
    The second comment period closed as scheduled on July 12, 2004. On August 11, 2004,
    CMS issued its final rule for fiscal year 2005. See generally Medicare Program; Changes to the
    Hospital Inpatient Prospective Payment Systems and Fiscal Year 2005 Rates (“2005 Final
    Rule”), 69 Fed. Reg. 48,916 (Aug. 11, 2004). Regarding the treatment of dual-eligible exhausted
    days, the Secretary acknowledged, for the first time in the Federal Register, that the agency had
    “misstated our current policy with regard to the treatment of certain inpatient days for dual-
    eligibles in the proposed rule of May 19, 2003,” 
    id. at 49,098,
    and noted that “[a] notice to this
    effect was posted on CMS’s Web site on July 9, 2004,” 
    id. (internal citation
    omitted). The
    agency clarified that, “[i]n that proposed rule, we indicated that a dual-beneficiary is included in
    the Medicare fraction even after the patient’s Medicare Part A hospital coverage is exhausted.
    . . . This statement was not accurate. Our policy has been that only covered patient days are
    included in the Medicare fraction.” 
    Id. The Secretary
    proceeded to address a variety of comments received during the comment
    period for the 2004 and 2005 Proposed Rules. First, the Secretary noted that CMS had “received
    numerous comments that commenters were disturbed and confused by our recent Web site posting
    regarding our policy on dual-eligible patient days,” 
    id., and that
    many commenters “believed that
    this posting was a modification or change in our current policy” that required “formal notification
    by CMS” and an “opportunity for providers to comment,” 
    id. The Secretary
    responded that the
    notice “was not a change in our current policy” and that, because the posting “was not a new
    proposal or policy change,” the Secretary did not need to “utilize the rule making process in
    correcting a misstatement that was made in the May 19, 2003 proposed rule regarding this
    policy.” 
    Id. 16 The
    Secretary acknowledged that other commenters had opposed the proposal to begin
    counting dual-eligible exhausted days in the Medicaid fraction rather than the Medicare fraction.
    
    Id. Specifically, commenters
    “objected that the proposal would result in a reduction of DSH
    payments when the exhausted coverage days are removed from the Medicare fraction and
    included in the Medicaid fraction” and that such a change “would dilute the value of that day
    and, therefore, reduce the overall patient percentage and the resulting DSH payment adjustment.”
    
    Id. The Secretary
    highlighted one commenter who “observed that a patient who exhausts
    coverage for inpatient hospital services still remains entitled to other Medicare Part A benefits”
    and found it “difficult to reconcile the position that these patients are not entitled to Medicare
    Part A benefits when they can receive other covered Part A services.” 
    Id. Still other
    commenters
    “stated that these days should not be included in either the Medicare or Medicaid fraction.” 
    Id. Finally, the
    Secretary noted that many commenters “indicated that the proposal would put an
    increased administrative burden on the hospitals to support including these patient days in the
    Medicaid fraction.” 
    Id. In response
    to these comments, the Secretary explained that this change had been
    proposed “to facilitate consistent handling of these days across all hospitals.” 
    Id. The Secretary
    acknowledged, however, “the point raised by the commenter that beneficiaries who have exhausted
    their Medicare Part A inpatient coverage may still be entitled to other Part A benefits.” 
    Id. The Secretary
    “agree[d] with the commenter that including the days in the Medicare fraction has a
    greater impact on a hospital’s DSH patient percentage than including the days in the Medicaid
    fraction,” and that this outcome was “necessarily so because the denominator of the Medicare
    fraction (total Medicare inpatient days) is smaller than the denominator of the Medicaid fraction
    (total inpatient days).” 
    Id. Nevertheless, the
    Secretary “disagree[d] with the commenter’s
    17
    assertion that including days in the Medicaid fraction instead of the Medicare fraction always
    results in a reduction in DSH payments,” noting that, in some cases, “[t]he inclusion of such
    patient days in the Medicare fraction has the result of decreasing the Medicare fraction in the
    DSH percentage.” 
    Id. 3 After
    reviewing these comments, the Secretary stated the final rule:
    For these reasons, we have decided not to finalize our proposal stated in the May 19,
    2003 proposed rule to include dual-eligible beneficiaries who have exhausted their Part A
    hospital coverage in the Medicaid fraction. Instead, we are adopting a policy to include
    the days associated with dual-eligible beneficiaries in the Medicare fraction, whether or
    not the beneficiary has exhausted Medicare Part A hospital coverage. If the patient is
    entitled to Medicare Part A and SSI, the patient days will be included in both the
    numerator and denominator of the Medicare fraction. This policy will be effective for
    discharges occurring on or after October 1, 2004. We are revising our regulations at
    § 412.106(b)(2)(i) to include the days associated with dual-eligible beneficiaries in the
    Medicare fraction of the DSH calculation.
    
    Id. at 49,099.
    In other words, the 2005 Final Rule formally adopted the policy that was
    mistakenly put forth as the status quo in the 2004 Proposed Rule: including dual-eligible days in
    the Medicare fraction, regardless of whether Part A coverage had been exhausted.
    The final rule was eventually codified at 42 C.F.R. § 412.106(b)(2)(i). Before the 2005
    Final Rule, that section explained that the Medicare fraction was calculated by determining the
    “number of covered patient days” that were “associated with discharges occurring during each
    month” and that were “furnished to patients who during that month were entitled to both
    Medicare Part A and SSI, excluding those patients who received only State supplementation.”
    42 C.F.R. § 412.106(b)(2)(i) (2003) (emphasis added). After the 2005 Final Rule was adopted,
    3
    Specifically, the Secretary noted that “if a dual-eligible beneficiary has not exhausted Medicare Part A
    inpatient benefits, and is not entitled to SSI benefits, the patient days for that beneficiary are included in the
    Medicare fraction, but only in the denominator of the Medicare fraction (because the patient is not entitled to SSI
    benefits),” which would decrease the Medicare fraction in the DSH adjustment. 2005 Final Rule, 69 Fed. Reg. at
    49,098.
    18
    this provision was amended to begin by determining the “number of patient days,” with the word
    “covered” omitted. 42 C.F.R. § 412.106(b)(2)(i) (2004).
    C.      The Pending Lawsuit
    The plaintiffs in this case are “general acute care hospitals” from across the country,
    Compl. ¶ 31, that “furnish[ ] inpatient and outpatient services to, inter alia, patients entitled to
    benefits under the Medicare program,” 
    id. ¶ 4.
    The hospitals participate in the Medicare program
    as providers of services and receive reimbursements from the program on a regular basis. At
    issue in this case are the hospitals’ reimbursements for the 2005, 2006, and 2007 fiscal years.
    See 
    id. ¶¶ 4–30.
    The plaintiffs contend that, as a result of the 2005 Final Rule, they received
    “lesser [DSH] payments than the DSH amounts to which they were entitled, or no DSH
    payments at all.” Pls.’ Mot. at 1.
    Each plaintiff “filed a request for hearing within 180 days of receiving a Notice of
    Program Reimbursement” from its fiscal intermediary, or “within 180 days of the expiration of
    the 12 month period for issuance of a Notice of Program Reimbursement.” Compl. ¶ 77. On
    November 29, 2016, the plaintiffs requested that the PRRB grant EJR so that they could seek
    judicial review of the 2005 Final Rule. AR at 1. On December 20, 2016, the PRRB assumed
    jurisdiction of the plaintiffs’ appeals and granted EJR, holding that the PRRB was “without
    authority to decide the legal question of whether 42 C.F.R. § 412.106(b)(2)(i) is valid.” 
    Id. at 6.
    4
    The plaintiffs filed their complaint in this action within sixty days of the PRRB’s decision,
    arguing that the 2005 Final Rule was the result of a procedurally invalid rulemaking and that the
    rule itself was arbitrary and capricious. Compl. ¶¶ 80–88. 5 The plaintiffs sought vacatur of the
    4
    The West Anaheim plaintiffs requested EJR on February 23, 2017, and on March 15, 2017, the PRRB
    decided that it lacked jurisdiction over the plaintiffs’ challenge. See AR at 320–22.
    5
    The West Anaheim complaint was filed on May 11, 2017. See W. Anaheim Med. Ctr. v. Azar, No. 17-cv-
    880, Compl. (“West Anaheim Compl.”) at ¶ 50, ECF No. 1.
    19
    2005 Final Rule and the corresponding CMS Rule 1498R-2 “insofar as they require exhausted
    days and other non-covered days such as [Medicare Secondary Payer (“MSP”)] days to be
    counted in the Medicare Fraction” and “requiring the Secretary to recalculate the DSH patient
    percentages of the Plaintiff Hospitals by not counting exhausted days, and other non-covered
    days such as MSP days, in the Medicare Fraction for the cost years at issue.” 
    Id. at 28.
    After both the plaintiffs’ motion and the defendant’s cross-motion had been filed, but
    before briefing on those motions was complete, the parties jointly moved to consolidate this
    action and two other similar actions. See generally W. Anaheim Med. Ctr. v. Azar, No. 17-cv-
    315 (D.D.C. filed Feb. 21, 2017); Dall. Reg’l Med. Ctr. v. Azar, No. 17-cv-880 (D.D.C. filed
    May 11, 2017). That motion was granted and the cases were consolidated on January 9, 2018, at
    which time the West Anaheim and Dallas Regional cases were closed. See Order, dated January
    9, 2018, ECF No. 20; Minute Entry (January 9, 2018). The plaintiffs’ motion for summary
    judgment and the defendant’s cross-motion for summary judgment are now ripe for review.
    II.    LEGAL STANDARD
    A.      Summary Judgment
    Pursuant to Federal Rule of Civil Procedure 56, summary judgment may be granted when
    the court finds, based on the pleadings, depositions, affidavits, and other factual materials in the
    record, “that there is no genuine dispute as to any material fact and the movant is entitled to
    judgment as a matter of law.” FED. R. CIV. P. 56(a), (c); see also Tolan v. Cotton, 
    134 S. Ct. 1861
    , 1866 (2014) (per curiam); Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 247 (1986). “A
    genuine issue of material fact exists if the evidence, ‘viewed in a light most favorable to the
    nonmoving party,’ could support a reasonable jury’s verdict for the non-moving party.”
    Muwekma Ohlone Tribe v. Salazar, 
    708 F.3d 209
    , 215 (D.C. Cir. 2013) (quoting McCready v.
    Nicholson, 
    465 F.3d 1
    , 7 (D.C. Cir. 2006)).
    20
    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 (D.C. Cir. 2001) (footnote omitted)
    (collecting cases). Thus, this Court need not and ought not engage in lengthy 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 ours”). As a
    general rule, judicial review is limited to the administrative record, since “[i]t is black-letter
    administrative law that in an [Administrative Procedure Act] 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 omitted; second
    alteration in original); see also 5 U.S.C. § 706 (“[T]he court shall review the whole record or
    those parts of it cited by a party . . . .”); Fla. Power & Light Co. v. Lorion, 
    470 U.S. 729
    , 743
    (1985) (noting that when applying arbitrary and capricious standard under the APA, “[t]he focal
    point for judicial review should be the administrative record already in existence . . . .” (quoting
    Camp v. Pitts, 
    411 U.S. 138
    , 142 (1973))).
    B.      Administrative Procedure Act
    Under the APA, a reviewing court must set aside a challenged agency action that is found
    to be, inter alia, “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance
    with law,” 5 U.S.C. § 706(2)(A); “in excess of statutory jurisdiction, authority, or limitations, or
    short of statutory right,” 
    id. § 706(2)(C);
    or “without observance of procedure required by law,”
    
    id. § 706(2)(D);
    see also Otis Elevator Co. v. Sec’y of Labor, 
    762 F.3d 116
    , 120–21 (D.C. Cir.
    21
    2014) (citing Fabi Constr. Co. v. Sec’y of Labor, 
    370 F.3d 29
    , 33 (D.C. Cir. 2004)). The
    arbitrary or capricious provision, under § 706(2)(A), “is a catchall, picking up administrative
    misconduct not covered by the other more specific paragraphs” of the APA. Ass’n of Data
    Processing Serv. Orgs., Inc. v. Bd. of Governors of Fed. Reserve Sys. (“ADPSO”), 
    745 F.2d 677
    ,
    683 (D.C. Cir. 1984) (Scalia, J.).
    To pass arbitrary and capricious muster, “the agency must examine the relevant data and
    articulate a satisfactory explanation for its action including a rational connection between the
    facts found and the choice made.” Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co.
    (“State Farm”), 
    463 U.S. 29
    , 43 (1983) (internal quotation marks omitted). As the D.C. Circuit
    has explained, a party challenging an agency action as arbitrary and capricious “must show the
    agency action is not a product of reasoned decisionmaking.” Van Hollen, Jr. v. FEC, 
    811 F.3d 486
    , 495 (D.C. Cir. 2016). “This is ‘a heavy burden,’ since State Farm entails a ‘very deferential
    scope of review’ that forbids a court from ‘substitut[ing] its judgment for that of the agency.’”

    Particularly when “an agency has acted in an area in which it has ‘special expertise,’ the court
    must be particularly deferential to [the agency’s] determinations.” Sara Lee Corp. v. Am. Bakers

    512 F. Supp. 2d 32
    , 37 (D.D.C. 2007) (quoting Bldg. & Constr. Trades Dep’t,
    AFL-CIO v. Brock, 
    838 F.2d 1258
    , 1266 (D.C. Cir. 1988)). That said, “courts retain a role, and
    an important one, in ensuring that agencies have engaged in reasoned decisionmaking.”
    
    Judulang, 565 U.S. at 53
    . Simply put, “the agency must explain why it decided to act as it did.”
    Butte Cty. v. Hogen, 
    613 F.3d 190
    , 194 (D.C. Cir. 2010).
    22
    The D.C. Circuit has summarized the circumstances under which an agency action would
    normally be “arbitrary and capricious” to include “if the agency has relied on factors which
    Congress has not intended it to consider, entirely failed to consider an important aspect of the
    problem, offered an explanation for its decision that runs counter to the evidence before the
    agency, or is so implausible that it could not be ascribed to a difference in view or the product of
    agency expertise.” Pharm. Research & Mfrs. of Am. v. FTC,

    , 209 (D.C. Cir. 2015)
    (quoting State 
    Farm, 463 U.S. at 43
    ). Thus, when an agency “has failed to provide a reasoned
    explanation, or where the record belies the agency’s conclusion, [the court] must undo its
    action.” Cty. of L.A. v. Shalala, 
    192 F.3d 1005

    state its reasoning or to adopt an intelligible decisional standard is [ ] glaring [ ] we can declare
    with confidence that the agency action was arbitrary and capricious” (quoting Checkosky v. SEC,

    III.   DISCUSSION
    The plaintiffs challenge the 2005 Final Rule on two grounds. First, the plaintiffs argue
    that the 2005 Final Rule is procedurally deficient under the APA and the Medicare Act because
    the Rule was not a logical outgrowth of the proposed rules, thereby depriving affected hospitals
    23
    of fair notice and the ability to submit comments. Pls.’ Mem. at 9–19. 6 Second, the plaintiffs
    contend that the 2005 Final Rule is substantively invalid because it was not the result of reasoned
    decisionmaking. 
    Id. at 19–25.
    The defendant responds that the 2005 Final Rule was the logical
    outgrowth of the 2004 Proposed Rule and that the 2005 Final Rule adequately explains the
    Secretary’s reasoning. Def.’s Mem. at 13–23. These arguments are taken in turn.
    A.       The 2005 Final Rule Was Promulgated with Adequate Notice and Comment
    Procedures
    The plaintiffs contend that “[t]he rulemaking record leading up to the FY 2005 Final Rule
    demonstrates interested parties were not provided fair notice of the policy the Secretary
    ultimately finalized in his FY 2005 Final Rule” because “the Secretary proposed in the FY 2004
    Proposed Rule the exact opposite of the policy he summarily ‘finalized’ in the FY 2005 Final
    Rule.” Pls.’ Mem. at 10. The defendant counters that the APA’s notice requirement was
    satisfied because “[t]he final rule was a logical outgrowth of the Secretary’s proposal” in the
    2004 and 2005 Proposed Rules. Def.’s Mem. at 13. Notwithstanding the sloppy and confusing
    misstatements in the 2004 and 2005 Proposed Rules, which make this a close case, the defendant
    has the better argument.
    1.       The Logical Outgrowth Test
    The APA generally requires a federal agency engaged in rulemaking to engage in notice
    and comment procedures. See 5 U.S.C. § 553(b). Specifically, a “notice of proposed rule
    making” must be “published in the Federal Register” and notify the public of “the time, place,
    6
    Although the plaintiffs argue that the “2005 Final Rule is procedurally deficient under both the APA and
    the Medicare Act,” Pls.’ Mem. at 9 (capitalization omitted), the parties’ arguments are based only on the APA. See
    Pls.’ Mem. at 9–19; Def.’s Mem. at 13–18. As relevant to this dispute, the requirements of the APA and the
    Medicare Act are substantially similar: the Medicare Act provides that if a final regulation “is not a logical
    outgrowth of a previously published notice of proposed rulemaking or interim final rule, such provision shall be
    treated as a proposed regulation and shall not take effect until there is the further opportunity for public comment
    and a publication of the provision again as a final regulation.” 42 U.S.C. § 1395hh(a)(4). Thus, the conclusions
    reached on the APA claim are equally applicable to the Medicare Act claim.
    24
    and nature of public rule making proceedings”; “the legal authority under which the rule is
    proposed”; and “the terms or substance of the proposed rule or a description of the subjects and
    issues involved.” 
    Id. § 553(b)(1)–(3).
    Once an agency issues notice of a proposed rule,
    however, the agency is not required to finalize that proposed rule. Rather, “[a]gencies are free—
    indeed, they are encouraged—to modify proposed rules as a result of the comments they
    receive.” Ne. Md. Waste Disposal Auth. v. EPA, 
    358 F.3d 936
    , 951 (D.C. Cir. 2004).
    “Given the strictures of notice-and-comment rulemaking,” however, “an agency’s
    proposed rule and its final rule may differ only insofar as the latter is a ‘logical outgrowth’ of the
    former.” Envtl. Integrity Project v. EPA, 
    425 F.3d 992
    , 996 (D.C. Cir. 2005) (citing Shell Oil
    Co. v. EPA, 
    950 F.2d 741
    , 750–51 (D.C. Cir. 1991)); see also Allina Health Servs. v. Sebelius,
    
    746 F.3d 1102
    , 1107 (D.C. Cir. 2014) (“An agency may promulgate a rule that differs from a
    proposed rule only if the final rule is a ‘logical outgrowth’ of the proposed rule.” (citing Ass’n of
    Private Sector Colleges & Univs. v. Duncan, 
    681 F.3d 427
    , 442 (D.C. Cir. 2012))); City of
    Waukesha v. EPA, 
    320 F.3d 228
    , 245 (D.C. Cir. 2003) (“The traditional APA ‘logical outgrowth’
    test applies where an agency changes its final regulation in some way from the proposed
    regulation for which it provided notice and requested comment, as required under the APA.”).
    The “logical outgrowth” doctrine “does not extend to a final rule that finds no roots in the
    agency’s proposal because ‘[s]omething is not a logical outgrowth of nothing,’” Envtl. Integrity
    
    Project, 425 F.3d at 996
    (alteration in original) (quoting Kooritzky v. Reich, 
    17 F.3d 1509
    , 1513
    (D.C. Cir. 1994)), nor does the doctrine apply “where interested parties would have had to
    ‘divine [the agency’s] unspoken thoughts,’ because the final rule was ‘surprisingly distant’ from
    the Agency’s proposal,” 
    id. (internal citation
    s omitted) (quoting Ariz. Pub. Serv. Co. v. EPA, 
    211 F.3d 1280
    , 1299 (D.C. Cir. 2000), and Int’l Union, United Mine Workers of Am. v. Mine Safety
    25
    & Health Admin., 
    407 F.3d 1250
    , 1260 (D.C. Cir. 2005)). That is, courts will “refuse[ ] to allow
    agencies to use the rulemaking process to pull a surprise switcheroo on regulated entities.” 
    Id. A final
    rule is considered a logical outgrowth of a proposed rule “only if interested parties
    ‘should have anticipated’ that the change was possible, and thus reasonably should have filed
    their comments on the subject during the notice-and-comment period.” Int’l 
    Union, 407 F.3d at 1259
    (internal quotation marks omitted) (quoting Ne. Md. Waste Disposal 
    Auth., 358 F.3d at 952
    ); see also 
    Allina, 746 F.3d at 1107
    (“A final rule is a logical outgrowth if affected parties
    should have anticipated that the relevant modification was possible.” (quoting CSX Transp., Inc.
    v. Surface Transp. Bd., 
    584 F.3d 1076
    , 1080 (D.C. Cir. 2009))). “[W]hile the ‘logical outgrowth’
    standard does not require the agency to assiduously lay out every detail of a proposed rule for
    comment, it does require that the ‘agency . . . publish notice of either the substance of a proposed
    rule or a description of the subjects and issues covered by a proposed rule.’” Horsehead Res.

    (quoting Fertilizer Inst. v. EPA, 
    935 F.2d 1303
    , 1310–11 (D.C. Cir. 1991)). As the D.C. Circuit
    has noted, “[o]ne logical outgrowth of a proposal is surely . . . to refrain from taking the
    proposed step.” Am. Iron & Steel Inst. v. EPA, 
    886 F.2d 390
    , 400 (D.C. Cir. 1989).
    2.      Analysis
    The 2005 Final Rule is a logical outgrowth of the 2004 Proposed Rule. In the 2004
    Proposed Rule, the Secretary explained that the current policy was to include dual-eligible
    exhausted days “in the Medicare fraction before and after Medicare coverage is exhausted.”
    2004 Proposed Rule, 68 Fed. Reg. at 27,207. The Secretary then “propos[ed] to change our policy,
    to begin to count in the Medicaid fraction of the DSH patient percentage the patient days of dual-
    eligible Medicare beneficiaries whose Medicare coverage has expired.” 
    Id. The 2004
    Proposed
    26
    Rule thus put parties on notice that either of these two options might be adopted. Indeed, the
    Secretary’s stated current policy—including dual-eligible exhausted days in the Medicare
    fraction—is precisely the rule that was ultimately adopted in the 2005 Final Rule. In the Final
    Rule, the Secretary explained that “we have decided not to finalize our proposal stated in the
    May 19, 2003 proposed rule” and that, “[i]nstead, we are adopting a policy to include the days
    associated with dual-eligible beneficiaries in the Medicare fraction, whether or not the beneficiary
    has exhausted Medicare Part A hospital coverage.” 2005 Final Rule, 69 Fed. Reg. at 49,099.
    The plaintiffs posit that merely “mention[ing] in a proposed rule [ ] the policy ultimately
    adopted” does not “put parties on notice that the agency may adopt the mentioned course of
    action,” Pls.’ Opp’n Def.’s Cross-Mot. Summ. J. & Reply Supp. Mot. Summ. J. (“Pls.’ Reply”)
    at 2, ECF No. 25. Even if that position were correct, the Secretary did more than merely
    “mention” the final policy here. Rather, the Secretary identified the two options that were
    available and chose between them. As the plaintiffs recognize, “the unambiguous language of
    the Medicare Act requires such days be included in one fraction or the other.” Pls.’ Mot. at 1–2. 7
    The 2004 Proposed Rule plainly identified these two possibilities, putting parties on notice that
    either one was a possible outcome. Moreover, the plain text of the 2004 Proposed Rule put
    interested parties on notice that the Secretary was considering “chang[ing] our policy” and
    identified the rule that was ultimately adopted, thus providing the requisite notice.
    7
    The plaintiffs at times seem to dispute that dual-eligible exhausted days must be included in either the
    Medicare or the Medicaid fraction, arguing that, “complicating the matter, the actual practice prior to the rulemaking
    challenged in this case was that, at least for some years, such days were nonsensically excluded from both fractions.”
    Pls.’ Mem. at 12 (quoting Catholic Health 
    Initiatives, 718 F.3d at 921
    ). This dispute rests on a misreading of
    Catholic Health, which noted only that “the policy of excluding dual-eligible exhausted days from the Medicaid
    fraction was announced [in 2000], and the [2004] rulemaking was simply a reiteration of this position.” Catholic
    Health 
    Initiatives, 718 F.3d at 921
    . Catholic Health Initiatives does not indicate that the prior practice was to exclude
    dual-eligible exhausted days from both fractions. In addition, the plaintiffs have acknowledged that “the unambiguous
    language of the Medicare Act requires such days be included in one fraction or the other.” Pls.’ Mot. at 1–2.
    27
    Nor does the fact that the Secretary misstated the current policy affect this analysis. The
    2004 Proposed Rule clearly offered two options that were available to the Secretary: either the
    misstated “current policy” of including dual-eligible exhausted days in the Medicare fraction, or
    the proposed policy of including such days in the Medicaid fraction. Even though the stated
    “current policy” was, in fact, not the Secretary’s actual policy, the 2004 Proposed Rule gave
    interested parties notice that the mistaken current policy might be adopted, because “[o]ne
    logical outgrowth of a proposal is surely . . . to refrain from taking the proposed step.” New York
    v. EPA, 
    413 F.3d 3
    , 44 (D.C. Cir. 2005) (quoting Am. Iron & Steel 
    Inst., 886 F.2d at 400
    ).
    Furthermore, even though “[t]he Secretary eventually acknowledged his misstatements,”
    Pls.’ Mem. at 12, and though “the Secretary’s proposal negatively mention[ed] the policy
    ultimately adopted,” Pls.’ Reply at 4, these facts also do not invalidate the 2005 Final Rule.
    While the Secretary did acknowledge, both in a July 7, 2004, website posting and in the 2005
    Final Rule, that he had misstated the current policy, the 2004 Proposed Rule still adequately
    notified interested parties that both the misstated current policy and the proposed new policy
    were possible outcomes of the rulemaking process. The Secretary’s allegedly “negative[ ]
    mention” of the policy that was ultimately adopted does not preclude the Secretary from
    changing his outlook after reviewing comments on the virtues of that policy. Rather, the
    Secretary was free “to modify [the] proposed rule[ ] as a result of the comments [he] receive[d].”
    Ne. Md. Waste Disposal 
    Auth., 358 F.3d at 951
    .
    Indeed, the Administrative Record includes many comments opposing the proposed rule,
    indicating that commenters were on notice that the Secretary was deciding between two options:
    including dual-eligible exhausted days in either the Medicare fraction or the Medicaid fraction.
    Numerous commenters during both the initial and the second comment periods wrote in support
    28
    of the misstated status quo—that is, the policy that was ultimately adopted—to “urge that CMS
    not change the rules for counting dual-eligible days.” AR at 583R (comments of Healthcare
    Association of New York State); see also 
    id. at 428R
    (comments of American Hospital
    Association) (“There are important reasons not to make this change.”). Only one commenter
    wrote in support of the proposed change. See 
    id. at 566R
    (comments of BlueCross BlueShield
    Association) (“We agree with the proposed change to include in the Medicaid percentage the
    patient days of dual-eligible Medicare beneficiaries whose Medicare coverage has expired.”).
    The plethora of comments in support of the rule ultimately adopted by the Secretary indicates
    that “[c]ommenters clearly understood that [this change] w[as] under consideration,” Appalachian
    Power Co. v. EPA, 
    135 F.3d 791
    , 816 (D.C. Cir. 1998), and is “evidence that sufficient notice
    was given,” Abington Mem’l Hosp. v. Burwell, 
    216 F. Supp. 3d 110
    , 134 (D.D.C. 2016).
    The plaintiffs discount “[t]he fact that some commenters actually submitted comments”
    advocating for the ultimately adopted proposal as “of little significance.” Fertilizer 
    Inst., 935 F.2d at 1312
    . In Fertilizer Institute, the EPA issued a proposed rule regarding the threshold
    “reportable quantity” (“RQ”) for radionuclides emitted into the environment, 
    id. at 1311,
    but the
    final rule instead created several “administrative exemptions” that “excuse parties from notifying
    the EPA when RQs of radionuclides are released,” 
    id. at 1310.
    The possibility of administrative
    exemptions was never mentioned in the proposed rule, but the EPA argued that the exemptions
    were a logical outgrowth in part because “several parties did in fact suggest that administrative
    exemptions be created.” 
    Id. at 1311.
    The D.C. Circuit concluded that “[t]he fact that some
    commenters actually submitted comments suggesting the creation of administrative exemptions
    is of little significance” because the proposed rule “was not sufficient to advise interested parties
    that comments directed to the creation of administrative exemptions should be made.” 
    Id. at 29
    1312. By contrast, in this case the issue of a proposed change and the possible outcomes of that
    change were directly mentioned in the 2004 Proposed Rule. The 2004 Proposed Rule expressly
    identified the two options available to the Secretary: either include dual-eligible exhausted days
    in the Medicare fraction, as the misstated current policy did, or adopt the proposed rule and
    include dual-eligible exhausted days in the Medicaid fraction. Interested parties were therefore
    on notice that they should comment either on whether the proposed policy should be adopted or
    on whether the stated status quo should be maintained.
    The plaintiffs primarily rest their argument on three cases, which ultimately offer little
    support. First, the plaintiffs cite Allina Health Services, which the plaintiffs characterize as
    “consider[ing] a virtually indistinguishable legal question,” resulting in the D.C. Circuit
    “concluding that a similar policy in the same FY 2005 Final Rule was procedurally invalid.”
    Pls.’ Mem. at 14. Allina Health Services addressed a provision of the 2005 Final Rule regarding
    the fraction in which Medicare Part C enrollees should be included for purposes of the DSH
    calculation. Allina Health 
    Servs., 746 F.3d at 1105
    . In the relevant portion of the 2004 Proposed
    Rule, the Secretary stated that “we are proposing to clarify that once a beneficiary elects
    Medicare Part C, those patient days attributable to the beneficiary should not be included in the
    Medicare fraction” but should instead be included in the Medicaid fraction. 2004 Proposed Rule,
    68 Fed. Reg. at 27,208 (emphasis added). In the 2005 Final Rule, however, the Secretary made
    no such “clarif[ication]” and instead “adopt[ed] a policy to include the patient days for [Part C]
    beneficiaries in the Medicare fraction”—the exact opposite of the policy the Secretary had
    “propos[ed] to clarify.” 2005 Final Rule, 69 Fed. Reg. at 49,099. The D.C. Circuit concluded
    that this result was not a logical outgrowth of the Secretary’s “propos[al] to clarify,” holding that
    “[t]he hospitals should not be held to have anticipated that the Secretary’s ‘proposal to clarify’
    30
    could have meant that the Secretary was open to reconsidering existing policy. The word
    ‘clarify’ does not suggest that a potential major issue is open for discussion.” Allina Health
    
    Servs., 746 F.3d at 1108
    .
    In this case, by contrast, the 2004 Proposed Rule clearly indicated that the Secretary was
    “proposing to change our policy.” 2004 Proposed Rule, 68 Fed. Reg. at 27,207. Unlike the
    proposal at issue in Allina, which merely stated that the Secretary was considering a
    “clarification,” the proposal at issue here put interested parties on notice not only that a change
    was possible but also that the proffered change might be rejected in favor of the stated current
    policy. Rather than using the word “clarify” to “unfairly mask[ ] a true policy change (and
    thereby depriv[e] the public of a meaningful opportunity to comment),” Abington Mem’l 
    Hosp., 216 F. Supp. 3d at 133
    , the Secretary’s 2004 Proposed Rule broadcast that he was considering a
    change and invited the public to comment on that proposal. By juxtaposing the stated current
    policy of including dual-eligible exhausted days in the Medicare fraction against the proposed
    policy of including such days in the Medicaid fraction, the 2004 Proposed Rule “characteriz[ed]
    [ ] the issue as an open, binary choice between two equally valid interpretations,” Allina Health
    Servs. v. Sebelius, 
    904 F. Supp. 2d 75
    , 90 (D.D.C. 2012), rev’d in part on other grounds by 
    746 F.3d 1102
    (D.C. Cir. 2014), and gave notice that either of the two interpretations would be
    adopted. Allina therefore does not control the outcome here, where interested parties properly
    were notified of a proposed change and given adequate opportunity to comment.
    The plaintiffs also contend that this case is similar to International Union, in which the
    D.C. Circuit struck down a final rule as not being a logical outgrowth of a proposed rule. See
    Pls.’ Mem. at 18–19. In that case, the Mine Safety and Health Administration issued a proposed
    rule that “[a] minimum air velocity of 300 feet per minute must be maintained” through point-
    31
    feed regulators in mines. Int’l 
    Union, 407 F.3d at 1259
    (internal quotation marks omitted;
    emphasis and alteration in original). The final rule, however, provided that “[t]he maximum air
    velocity in the belt entry must be no greater than 500 feet per minute.” 
    Id. (internal quotation
    marks omitted; emphasis and alteration in original). The D.C. Circuit concluded that “the
    maximum cap provision of the final rule was not a ‘logical outgrowth’ of the proposed rule,”
    which “did not indicate the possibility of a maximum cap much less one set at 500 [feet per
    minute].” 
    Id. at 1259–60.
    Here, by contrast, the 2004 Proposed Rule “indicate[d] the
    possibility” that dual-eligible exhausted days would be counted in the Medicare fraction, as was
    ultimately adopted, as well as the possibility that the stated current policy might be changed to
    count dual-eligible exhausted days in the Medicaid fraction. The notice concerns highlighted in
    International Union are thus not present in this case.
    Finally, the plaintiffs rely on Environmental Integrity Project to argue that “the Agency
    cannot bootstrap notice from comment” by pointing to comments received as evidence that
    proper notice was given. Pls.’ Reply at 6 (capitalization omitted). In that case, the
    Environmental Protection Agency (“EPA”) had proposed to “clarify” a reporting requirement by
    “codifying” an interpretation of the Clean Air Act that the EPA had embraced in prior litigation.
    Envtl. Integrity 
    Project, 425 F.3d at 994
    . In the final rule, however, the EPA decided not to
    clarify the relevant provision and instead “switched course and adopted the opposition position.”
    
    Id. at 995.
    In concluding that the EPA’s final rule was promulgated without proper notice and
    comment, the D.C. Circuit did not discuss the EPA’s argument that the final rule was justified on
    the basis of public comments. See 
    id. at 995–98.
    Rather, the D.C. Circuit noted that the EPA’s
    “propos[al] to codify its interpretation” did not provide adequate notice of “the Agency’s
    decision to repudiate its proposed interpretation and adopt its inverse.” 
    Id. at 998.
    Here, by
    32
    contrast, the Secretary plainly stated in the 2004 Proposed Rule that he was considering
    “chang[ing] our policy” from the existing policy of including dual-eligible exhausted days in the
    Medicare formula, thereby giving notice both that he was considering changing the policy and
    that, if the proposal was rejected, the stated current policy would remain in effect.
    Unlike the proposed rules in Allina Health Services, International Union, and
    Environmental Integrity Project, the 2004 Proposed Rule clearly stated that the Secretary was
    “proposing to change” a policy and identified the two possible choices: dual-eligible exhausted
    days would be included in either the Medicare fraction, or the Medicaid fraction. The 2005 Final
    Rule then adopted one of those two stated options. Accordingly, because the 2005 Final Rule is
    a logical outgrowth of the 2004 Proposed Rule, the 2005 Final Rule was promulgated with
    adequate notice and comment procedures and is not procedurally defective.
    B.      The 2005 Final Rule Was the Product of Reasoned Decisionmaking
    The plaintiffs next argue that “the policy finalized in the FY 2005 Final Rule was the
    product of arbitrary and capricious rulemaking” for three reasons: (1) “[t]he Secretary did not
    provide much by way of an explanation for his about-face in proposing to count exhausted days,”
    Pls.’ Mem. at 19; (2) “the Secretary apparently relied on a flawed understanding regarding the
    policy’s impact on DSH patient percentage calculations,” 
    id. at 22;
    and (3) “the Secretary
    continued to express confusion about his then-current policy and his new policy,” 
    id. at 24.
    The
    defendant counters that “[t]he Secretary adequately explained the choice he made,” Def.’s Mem.
    at 18, that the Secretary understood the impact of his proposal, see 
    id. at 21,
    and that the
    Secretary “was certainly aware that he was changing positions” when he revised the regulations,
    
    id. at 22.
    Again, although close, the defendant has the better arguments.
    33
    1.      Reasoned Decisionmaking
    “One of the basic procedural requirements of administrative rulemaking is that an agency
    must give adequate reasons for its decisions.” Encino Motorcars, LLC v. Navarro, 
    136 S. Ct. 2117
    , 2125 (2016); see also Pub. Citizen, Inc. v. FAA, 
    988 F.2d 186
    , 197 (D.C. Cir. 1993) (“The
    requirement that agency action not be arbitrary or capricious includes a requirement that the
    agency adequately explain its result.”). An agency therefore “must examine the relevant data
    and articulate a satisfactory explanation for its action including a rational connection between the
    facts found and the choice made.” Encino 
    Motorcars, 136 S. Ct. at 2125
    (quoting State 
    Farm, 463 U.S. at 43
    ). “Where the agency has failed to provide a reasoned explanation, or where the
    record belies the agency’s conclusion, [the court] must undo its action.” Cty. of 
    L.A., 192 F.3d at 1021
    (internal quotation marks and citation omitted).
    Under this framework, “[a]gencies are free to change their existing policies as long as
    they provide a reasoned explanation for the change.” Encino 
    Motorcars, 136 S. Ct. at 2125
    (citing Nat’l Cable & Telecomm. Ass’n v. Brand X Internet Servs., 
    545 U.S. 967
    , 981–82
    (2005)). To provide a “reasoned explanation” for a change in policy, the agency must at least
    “display awareness that it is changing position” and “show that there are good reasons for the
    new policy.” FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515 (2009); see also State
    
    Farm, 463 U.S. at 57
    (“An agency’s view of what is in the public interest may change, either
    with or without a change in circumstances. But an agency changing its course must supply a
    reasoned analysis.” (quoting Greater Bos. Television Corp. v. FCC, 
    444 F.2d 841
    , 852 (D.C. Cir.
    1971))). The agency “need not demonstrate to a court’s satisfaction that the reasons for the new
    policy are better than the reasons for the old one,” however.

    . Rather, “it
    suffices that the new policy is permissible under the statute, that there are good reasons for it,
    34
    and that the agency believes it to be better, which the conscious change of course adequately
    indicates.” 
    Id. 2. Analysis
    The 2005 Final Rule provides adequate explanations for the Secretary’s decision to begin
    counting dual-eligible exhausted days in the Medicare fraction. In the Final Rule, the Secretary
    detailed several themes of the comments received on the proposed rule, and he explained that the
    agency “agree[d] with” a comment that “including the days in the Medicare fraction has a greater
    impact on a hospital’s DSH patient percentage than including the days in the Medicaid fraction.”
    2005 Final Rule, 69 Fed. Reg. at 49,098. The Secretary also acknowledged another commenter’s
    argument that “beneficiaries who have exhausted their Medicare Part A inpatient coverage may
    still be entitled to other Part A benefits.” 
    Id. These two
    observations help explain the
    Secretary’s decision to count dual-eligible exhausted days in the Medicare fraction: the days
    would have “a greater impact” when included in the Medicare fraction, and patients who were
    entitled to other Part A benefits beyond inpatient hospital stays would logically be treated as still
    being “entitled to benefits under [Medicare] part A,” as the statutory definition of the Medicare
    fraction states. 42 U.S.C. § 1395ww(d)(5)(F)(vi)(I). Indeed, the DSH adjustment aims to
    compensate hospitals for treating sick, low-income patients—in other words, individuals who are
    likely to exhaust their Part A coverage but who remain in the hospital for treatment. Including
    patient days for these individuals in the Medicare fraction, where the days will often have a
    greater impact, furthers the purpose of the DSH adjustment. See Def.’s Mem. at 21.
    Notably, the Sixth Circuit has examined this same rule and concluded that the 2005 Final
    Rule “appears to be the result of a reasoned deliberative process, reflecting HHS’s experience in
    case-by-case administrative adjudications and in federal-court litigation, and its benefitting from
    35
    stakeholder input through notice-and-comment rulemaking.” Metro. Hosp. v. U.S. Dep’t of
    Health & Human Servs., 
    712 F.3d 248
    , 268 (6th Cir. 2013). In Metropolitan Hospital, the Sixth
    Circuit addressed whether the interpretation set forth in the 2005 Final Rule was entitled to
    Chevron deference, concluding that “the rulemaking process was not arbitrary and that the
    resulting regulation is a permissible construction of the DPP provision that warrants judicial
    deference under Chevron.” 
    Id. at 270.
    The Sixth Circuit noted that the Secretary had
    “appropriately considered the[ ] comments” without “blindly accept[ing] them as true,” 
    id. at 270,
    had “recognized th[e] inconsistency” in his prior interpretations of the phrase “entitled to
    benefits under [Medicare] part A,” 
    id. at 269,
    and had adopted the interpretation that would
    “facilitate consistent handling of these days across all hospitals,” 2005 Final Rule, 69 Fed. Reg.at
    49,098. The court thus concluded that the 2005 Final Rule was “the product of a reasoned
    analysis” rather than “an ad hoc determination meant to unduly restrict DSH adjustments.”
    Metro. 
    Hosp., 712 F.3d at 269
    . Although not binding on this Court, the Sixth Circuit’s reasoning
    is persuasive, lending strength to the defendant’s argument that the 2005 Final Rule was the
    product of reasoned decisionmaking.
    The plaintiffs nevertheless argue that “‘acknowledging a point’ and ‘agree[ing] with a
    commenter’ about the ‘impact’ of a policy do not provide the explanation demanded by the
    APA” because “the Secretary did not explain whether he agreed with the commenter point [sic]
    that the Secretary ‘acknowledged.’” Pls.’ Mem. at 20. The plaintiffs’ own brief belies that
    argument, as the plaintiffs recognize that the Secretary “agree[d] with [the] commenter.” 
    Id. After agreeing
    with this commenter, the Secretary went on to state that, “[f]or these reasons,” he
    had “decided not to finalize our proposal stated in the May 19, 2003 proposed rule.” 2005 Final
    36
    Rule, 69 Fed. Reg. at 49,099. The text of the 2005 Final Rule indicates that the Secretary carefully
    considered the comments and used those comments in reaching a well-reasoned decision.
    The plaintiffs also argue that the Secretary’s decision is arbitrary and capricious because
    the Secretary “apparently relied on a flawed understanding regarding the policy’s impact on
    DSH patient percentage calculations.” Pls.’ Mem. at 22. Specifically, the plaintiffs contend that
    the Secretary was “simply wrong” in his statement that “including the days in the Medicare
    Fraction has a greater impact on a hospital’s DSH patient percentage than including the days in
    the Medicaid Fraction,” 2005 Final Rule, 69 Fed. Reg. at 49,098, and in his statement that “[t]his
    is necessarily so because the denominator of the Medicare fraction (total Medicare inpatient
    days) is smaller than the denominator of the Medicaid fraction (total inpatient days),” 
    id. 8 The
    Secretary understood, however, that “including days in the Medicaid fraction instead of the
    Medicare fraction” would not always “result[ ] in a reduction in DSH payments.” 
    Id. Rather, the
    Secretary noted that “if a dual-eligible beneficiary has not exhausted Medicare Part A inpatient
    benefits, and is not entitled to SSI benefits, the patient days for that beneficiary are included in
    the Medicare fraction, but only in the denominator of the Medicare fraction (because the patient
    8
    In support of this argument, the plaintiffs offer a hypothetical situation: Suppose that, ignoring dual-eligible
    exhausted days, a hospital’s Medicare fraction is 7 percent (that is, 70 out of 1000 Medicare covered days are
    attributable to patients with unexhausted Part A benefits and also entitled to SSI benefits). Suppose also that, again
    ignoring dual-eligible exhausted days, the same hospital’s Medicaid fraction is also 7 percent (that is, 140 out of
    2000 total covered days were attributable to patients eligible for Medicaid but not entitled to Medicare Part A
    benefits). If this hospital also had 50 dual-eligible exhausted days for patients not entitled to SSI benefits, then
    including the exhausted days in the Medicare fraction would have the impact of reducing the Medicare fraction to
    6.67 percent (or 70 out of 1050 Medicare covered days), because the 50 exhausted days would be added only to the
    denominator. By contrast, including the exhausted days in the Medicaid fraction would increase the Medicaid fraction
    to 9.5 percent (or 190 out of 2000 days), because the days would be included in only the numerator. See Pls.’ Mem. at
    22–23. The plaintiffs’ example does not acknowledge, however, that if the hospital instead had 50 dual-eligible
    exhausted days for patients who were entitled to SSI benefits, then including the exhausted days in the Medicare
    fraction would increase the Medicare fraction from 7 percent to 11.4 percent (or 120 days out of 1050 Medicare
    covered days), while including those days in the Medicaid fraction would increase the Medicaid fraction from 7
    percent to only 9.5 percent, as shown above. Indeed, the poorest patients are those that are most likely to be entitled
    to SSI benefits, see Catholic 
    Health, 718 F.3d at 916
    (characterizing SSI as “welfare”), and the inclusion of their
    exhausted days in both the numerator and the denominator of the Medicare fraction will therefore have the effect,
    generally, of increasing the DPP more than including those days in the Medicaid fraction would increase the DPP.
    37
    is not entitled to SSI benefits).” 
    Id. The Secretary
    further stated that “[t]he inclusion of such
    patient days in the Medicare fraction has the result of decreasing the Medicare fraction in the
    DSH patient percentage,” 
    id., a recognition
    in line with the hypothetical presented in the
    plaintiffs’ brief. See note 
    8, supra
    . As the defendant argues, “Plaintiffs are simply wrong to
    suggest that the Secretary was unaware of this possible effect.” Def.’s Mem. at 21.
    The plaintiffs also argue that the final rule was arbitrary and capricious because “the
    Secretary failed to acknowledge the policy he was changing.” Pls.’ Mem. at 24. The 2005 Final
    Rule expressly states, however, that “[o]ur policy has been that only covered [that is, unexhausted]
    patient days are included in the Medicare fraction.” 2005 Final Rule, 69 Fed. Reg. at 49,098. The
    Secretary also noted that he had “inadvertently misstated” the current policy in the 2004 Proposed
    Rule and included a link to the July 7, 2004, website posting notifying the public of that
    misstatement. 
    Id. While the
    Secretary could have been clearer throughout the rulemaking process
    regarding the current policy and the proposed changes to current policy, the Secretary did
    acknowledge the policy that he was changing, as required by the APA. See 
    Fox, 556 U.S. at 515
    .
    The plaintiffs also allege that the Secretary “utterly failed to acknowledge that removing
    the reference to ‘covered’ days from 42 C.F.R. § 412.106(b)(2) . . . would have an effect on other
    non-covered days such as MSP days”—that is, days for which a patient does not receive
    Medicare Part A benefits because another entity paid for the inpatient hospital stay. Pls.’ Mem.
    at 25. Notably, the plaintiffs raised this claim as part of their argument that the 2005 Final Rule
    was arbitrary and capricious, not that the 2005 Final Rule was procedurally deficient, thereby
    waiving the latter argument. See Pl.’s Mem. at 25 (arguing that “[t]he Secretary’s policy of
    counting non-covered days such as exhausted days and MSP days in the Medicare Fraction is
    substantively invalid, as the Secretary did not provide a reasoned explanation for the change and
    38
    did not even demonstrate a basic understanding of his prior policy, the change he promulgated,
    and the effects of the change”). Nevertheless, even assuming both arguments were properly
    raised, the Secretary’s failure to specifically discuss the 2005 Final Rule’s impact on MSP days
    does not invalidate the rule on either score. The Secretary stated in the 2005 Final Rule that
    “[o]ur policy has been that only covered patient days are included in the Medicare fraction,”
    2005 Final Rule, 69 Fed. Reg. 49,098, meaning that only days for which Medicare Part A
    benefits were actually received were included in the Medicare fraction. That statement would
    also exclude from the Medicare fraction MSP days, or days when a patient is entitled to
    Medicare Part A benefits but does not actually receive those benefits because a secondary payer
    covered the costs.
    Moreover, as the defendant points out, the 2005 Final Rule concerned whether a patient
    could be “entitled to benefits under [Medicare] Part A” when the patient did not actually receive
    any Part A benefits. Def.’s Reply Supp. Cross-Mot. Summ. J. (“Def.’s Reply”) at 8 n.3, ECF
    No. 29. “If the Secretary answered in the affirmative (as he ultimately did) then patient days for
    Medicare beneficiaries would be included in the Medicare fraction, regardless of whether the
    program paid for their care on that day.” 
    Id. That policy
    logically would also apply to a patient
    who was entitled to benefits under Part A, but who did not actually receive any Part A benefits
    because payment had already been made by another source. Indeed, the D.C. Circuit has
    accorded deference to the Secretary’s position that “entitlement to Medicare benefits is simply a
    matter of meeting the statutory criteria, not a matter of receiving payment.” Catholic Health
    
    Initiatives, 718 F.3d at 919
    –20 (citing 42 C.F.R. § 400.202 (“Entitled means that an individual
    meets all the requirements for Medicare benefits.”)). Four appellate courts also have concluded
    that “the Medicaid proxy includes all patient days for which a person was eligible for Medicaid
    39
    benefits, whether or not Medicaid actually paid for those days of service,” Cabell Huntington
    Hosp. v. Shalala, 
    101 F.3d 984
    , 991 (4th Cir. 1996), indicating that the same conclusion about
    the Medicare proxy reasonably could have been expected and strengthening the defendant’s
    argument that “there is no reason to think that the Secretary failed to realize” that his
    interpretation “would have consequences beyond the dual-eligible patient days that were the
    explicit subject of this rulemaking.” Def.’s Mem. at 22; see also 
    id. at 5
    n.1; Legacy Emanuel
    Hosp. v. Shalala, 
    97 F.3d 1261
    , 1265 (9th Cir. 1996); Deaconess Health Servs. Corp. v. Shalala,
    
    83 F.3d 1041
    (Mem.) (8th Cir. 1996) (per curiam); Jewish Hosp. v. Sec’y of Health & Human
    Servs., 
    19 F.3d 270
    , 276 (6th Cir. 1994). As the defendant argues, “[t]hat the Secretary did not
    provide an elaborate typology of all such days” that might possibly have been affected by the
    rule “does not undermine the rationality of his decision to adopt this interpretation.” Def.’s
    Reply at 10 n.4. The failure to specifically mention MSP days thus does not render the 2005
    Final Rule procedurally deficient or arbitrary and capricious.
    Finally, the plaintiffs repeatedly contend that the Secretary’s “actual practice prior to the
    rulemaking challenged in this case” was “nonsensical” and must be corrected. Pls.’ Mem. at 7
    (“[T]he actual practice prior to the rulemaking challenged in this case was that, at least for some
    years, such days were nonsensically excluded from both fractions.”); 
    id. at 26
    (“Any pre-FY
    2005 practice of excluding such days from both fractions is nonsensical.”). As already
    discussed, it is not clear that the Secretary had such a practice of excluding dual-eligible
    exhausted days from both fractions. See supra note 7. Nevertheless, to the extent that the
    plaintiffs suggest the Secretary’s practice prior to the 2005 Final Rule was “nonsensical,” the
    2005 Final Rule is an improvement as it sets forth a clear policy of including dual-eligible
    exhausted days in the Medicare fraction.
    40
    Given that the FY 2005 Final Rule is procedurally sound and the product of reasoned
    decisionmaking, it is unnecessary to address the plaintiffs’ argument that “CMS Ruling 1498R
    must also be vacated to the extent based on the deficient and invalid policy in the FY 2005 Final
    Rule,” Pls.’ Mem. at 26, and the plaintiffs’ argument that vacatur with an injunction, rather than
    a remand, is the appropriate remedy, 
    id. at 25–28.
    IV.    CONCLUSION
    For the foregoing reasons, the plaintiffs’ motions for summary judgment are denied and
    the defendant’s cross-motions for summary judgment are granted. An appropriate Order
    accompanies this Memorandum Opinion.
