    Appeal from the United States District Court
    for the Southern District of Mississippi
    Before REAVLEY, ELROD, and WILLETT, Circuit Judges.
    DON R. WILLETT, Circuit Judge:
    One tricky area of America’s uniquely complex healthcare “system” is the
    labyrinth of acronyms and formulae that govern Medicare funding. In this
    appeal, two Mississippi hospitals insist that the federal government skimped
    on their Disproportionate Share Hospital (or DSH—pronounced “dish”)
    payments—special funding to institutions serving large numbers of indigent
    patients. To determine if the hospitals were rightly compensated, we must
    determine if a certain DSH-related fraction—specifically the numerator—was
    rightly calculated. The answer, though, turns less on figuring numbers than
    on figuring out words. And all language cases share a common denominator:
    Judges must defer to plain language, not to parties seeking to elude it.

    No. 18-60227
    Here, the district court gave “substantial deference” to the interpretation
    of the Department of Health and Human Services (HHS), which read the
    relevant statute and regulation to exclude from the numerator Mississippi’s
    uncompensated care pool (UCCP) patient days. 1 Upshot: smaller numerator,
    smaller fraction, smaller funding. But HHS’s reading of the fraction was
    improper, as was the district court’s deference to it. The governing provisions
    unambiguously require HHS to include such patient days. By excluding
    instead of including, HHS committed a fraction infraction—and flouted the
    law’s plain language.
    As HHS’s position is foreclosed by the text and structure of the relevant
    provisions, we REVERSE the district court’s judgment and REMAND to the
    Medicare Administrative Contractor (MAC) to include the UCCP days in the
    hospitals’ DSH calculation.
    I. Background
    A.    The Statutory and Regulatory Framework
    Medicare is a federal health insurance program for the elderly and
    disabled. 2 It is, as the Supreme Court recently observed, America’s “largest
    federal program after Social Security,” spending roughly “$700 billion annually
    to provide health insurance for nearly 60 million aged or disabled Americans,
    nearly one-fifth of the Nation’s population.” 3 Together, Social Security and
    Medicare make up about 60 percent of all federal spending.
    Medicare compensates hospitals for inpatient services under a
    prospective payment system, which determines national rates for various
    services. 4 These rates are subject to myriad adjustments. 5 This case deals with

    No. 18-60227
    a Medicare adjustment for DSH hospitals—those that serve a “significantly
    disproportionate number of low-income patients.” 6
    Whether and to what extent a hospital qualifies for a Medicare DSH
    adjustment hinges on how many days a hospital treated people who are eligible
    for Medicaid (not to be confused with Medicare). Medicaid, the third-largest
    mandatory program in the federal budget, 7 is the cooperative federal-state
    health insurance program for low-income people. 8 HHS calculates a hospital’s
    DSH adjustment using a formula called the “disproportionate patient
    percentage.” 9 The “disproportionate patient percentage” is the sum of two
    fractions, a Medicare fraction and a Medicaid fraction. This case deals with the
    Medicaid fraction:
    the 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 plan approved under [Medicaid], but who
    were not entitled to benefits under [Medicare], and the
    denominator of which is the total number of the hospital’s patient
    days for such period. 10
    When making a DSH calculation you have to ask how many days a hospital
    treated “patients who . . . were eligible for medical assistance under a State
    plan approved under [Medicaid].” 11 But there’s a little more to it. When
    Congress passed the Deficit Reduction Act of 2005, it added this to the DSH
    Medicaid fraction statute:

    No. 18-60227
    In determining [the Medicaid fraction,] 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 plan approved under [Medicaid], the Secretary may, to the
    extent and for the period the Secretary determines appropriate,
    include patient days of patients not so eligible but who are
    regarded as such because they receive benefits under a
    demonstration project approved under title XI. 12
    So, the Medicaid fraction’s numerator includes both (1) days a hospital treated
    patients who were Medicaid-eligible, and (2) days a hospital treated patients
    who are regarded as Medicaid-eligible because they received demonstration
    project benefits. What are demonstration projects? A little more context is in
    order.
    One does not simply receive federal funding. 13 To participate in the
    Medicaid program, a state must submit a plan for medical assistance to the
    Centers for Medicare & Medicaid Services (CMS) for approval (this is called
    the “State plan”). The State plan must specify who will receive medical
    assistance, what kind of medical care and services will be offered, and so on. 14
    CMS must then approve the plan. 15 Once a plan is approved, a state may
    receive matching payments from the federal government based on amounts
    that the state “expended . . . as medical assistance under the State plan.” 16
    Title XI § 1115 of the Social Security Act, however, authorizes the
    Secretary of HHS to waive certain Medicaid requirements for experimental,
    pilot, or demonstration projects that, in his judgment, will “assist in promoting

    the objectives of [Medicaid].” 17 In other words, these § 1115 waivers are
    Congress’s green light to the Secretary to relax the usual state-plan-approval
    requirements. Section 1115 waivers “shall, to the extent and for the period
    prescribed by the Secretary, be regarded as expenditures under [Medicaid].” 18
    Thus, these § 1115 demonstration projects provide benefits to people who
    wouldn’t otherwise be eligible for Medicaid benefits; and the costs of these
    benefits are treated as if they are matchable Medicaid expenditures. This is
    crucial for our case because patients who were ineligible for Medicaid but
    received benefits under a § 1115 demonstration project count for Medicaid
    fraction numerator purposes—resulting in a beefier reimbursement for
    hospitals.
    We’ve introduced the major statutory puzzle pieces. But there’s a
    regulatory piece too, 42 C.F.R. § 412.106(b)(4). That regulation says:
    (4) Second computation. The fiscal intermediary determines . . .
    the number of the hospital’s patient days of service for which
    patients were eligible for Medicaid but not entitled to Medicare
    Part A, and divides that number by the total number of patient
    days in the same period. For purposes of this second computation,
    the following requirements apply:
    (i) For purposes of this computation, a patient is deemed eligible
    for Medicaid on a given day only if the patient is eligible for
    inpatient hospital services under an approved State Medicaid plan
    or under a waiver authorized under section 1115(a)(2) of the Act
    on that day, regardless of whether particular items or services
    were covered or paid under the State plan or the authorized
    waiver.
    (ii) . . . [H]ospitals may include all days attributable to populations
    eligible for [Medicaid] matching payments through a waiver
    approved under section 1115 of the Social Security Act. 19
    17  See Public Welfare Amendments of 1962, Pub. L. No. 87–543, § 122, 76 Stat. 172,
    192, codified at 42 U.S.C. § 1315.

    No. 18-60227
    This regulation is straightforward. The fiscal intermediary—a private third
    party tasked with auditing, reporting, and reimbursing hospitals through
    Medicare and Medicaid—must figure out which days to include in the Medicaid
    fraction numerator. From here, 42 C.F.R. § 412.106(b)(4)(i) describes a
    necessary condition: If a day is going to be included in the numerator, the
    patient underlying that day must have either (1) been “eligible for inpatient
    hospital services under an approved State Medicaid plan,”—the State plan
    that goes through the typical HHS approval process—or (2) eligible “under a
    waiver authorized under section 1115(a)(2).” Subsection (ii) lays out a
    sufficient condition, giving hospitals permission to go ahead and include days
    attributed to § 1115 populations. 20
    B.    The Deficit Reduction Act of 2005 and Hurricane Katrina
    We noted above how the Deficit Reduction Act modified the Medicaid
    fraction statute (by tacking on the “regarded as such” language). But the Act
    also funded a Hurricane Katrina demonstration project:
    (a) IN GENERAL.—The Secretary . . . shall pay to each eligible
    State . . . :
    (1) Under the authority of an approved Multi–State Section 1115
    Demonstration Project . . .
    (A) with respect to evacuees receiving health care under such
    project, for the non-Federal share of expenditures:
    (i) for medical assistance furnished under [Medicaid], and
    (ii) for child health assistance furnished under [Medicare];
    (B) with respect to evacuees who do not have other coverage for
    such assistance through insurance, including (but not limited to)
    private insurance, under [Medicaid] or [Medicare], or under State-
    funded health insurance programs, for the total uncompensated
    care costs incurred for medically necessary services and supplies
    or premium assistance for such persons, and for those evacuees
    receiving medical assistance under the project for the total
    20   42 C.F.R. § 412.106(b)(4)(ii).

    Case: 18-60227              Document: 00514990219        Page: 7    Date Filed: 06/10/2019
    No. 18-60227
    uncompensated care costs incurred for medically necessary
    services and supplies beyond those included as medical assistance
    or child health assistance under the State’s approved plan under
    [Medicaid] or [Medicare] . . . . 21
    Combined with the rest of the Deficit Reduction Act of 2005, this boils down to:
    Congress directs the Secretary to approve a large demonstration project. 22
    From here, the statute breaks down funding for health care services into four
    populations: (1) evacuees receiving health care under the project; (2) affected
    individuals (people located in disaster relief counties) receiving health care
    under the project; 23 (3) evacuees who were uninsured and not Medicaid-
    eligible; and (4) affected individuals who were uninsured and not Medicaid-
    eligible. 24
    The “non-Federal share” funds go towards the share of costs that State
    Medicaid programs would’ve had to bear anyway—costs that were eligible for
    federal matching funds under Medicaid. Conversely, costs of care for
    uninsured, non-Medicaid-eligible individuals and evacuees—costs that the
    State Medicaid programs and federal funds would not normally have covered—
    were simply covered by federal funds appropriated under the Deficit Reduction
    Act not related to Medicaid funds.
    In September 2005, CMS approved Mississippi’s § 1115 waiver to
    provide Medicaid and State Children’s Health Insurance Program (SCHIP)
    coverage for evacuees displaced from Louisiana, Mississippi, Alabama, and
    Florida,         and     those      otherwise   affected    by    Hurricane      Katrina.     The
    demonstration project extended and expedited Medicaid/SCHIP eligibility to

    individuals who were displaced to Mississippi because of Katrina and met
    certain income-eligibility standards.
    The demonstration project also permitted Mississippi to reimburse
    providers that incurred uncompensated care costs for medically necessary
    services and supplies for Katrina evacuees and affected individuals who did
    not have coverage under Medicare, Medicaid, SCHIP, private insurance, or
    under State-funded health insurance programs for a five-month period—the
    uncompensated care pool (UCCP). CMS approved Mississippi’s UCCP in the
    September letter and UCCP plan details in a March 2006 letter.
    Because   of    the   unanticipated   surge   of    patients   post-Katrina,
    Mississippi’s Medicaid program had no way to receive and electronically
    process claims under the § 1115 waiver. Instead, hospitals were directed to
    submit paper claims in “batches” of 50 that did not differentiate between
    Medicaid-eligible evacuees and affected individuals under the UCCP pool. The
    hospitals in this case counted inpatient days for all individuals who received
    inpatient services (in other words, “Katrina days”) under the waiver in the
    Medicaid fraction numerator in their 2005 and 2006 cost reports—including
    UCCP patient days.
    C.    The Administrative and Judicial Proceedings Below
    The Medicare Administrative Contractor excluded all UCCP days in the
    final settlement of the hospitals’ cost reports. The hospitals appealed the
    Contractor’s decision to the Provider Reimbursement Review Board. The
    Review Board reasoned that the plain statutory and regulatory text governing
    the DSH adjustment requires all inpatient days provided under the Katrina
    waiver to be included in the Medicaid fraction numerator; the UCCP was under
    the Katrina waiver, so UCCP days go into the numerator.
    Having lost that round, HHS appealed to the CMS Administrator. The
    Administrator analogized the Mississippi UCCP to state-only general
    8

    No. 18-60227
    assistance days and charity care/uncompensated care days, noting that courts
    have consistently held that such days don’t involve patients who are “eligible
    for medical assistance under a State plan approved under [Medicaid].” 25 The
    Administrator reiterated that days the hospitals treated UCCP patients were
    not days involving patients who “were eligible for medical assistance under a
    State plan approved under [Medicaid].” 26 The Administrator also thought that
    UCCP days weren’t “attributable to populations eligible for [Medicaid]
    matching payments through a waiver approved under section 1115” and were
    excluded from the DSH adjustment by regulation. 27 So the Administrator
    excluded the UCCP days from the Medicaid fraction.
    The district court agreed with the Administrator. The district court
    began by explaining how deferential the standard of review is. Believing that
    it was required to give “substantial deference to an agency’s construction of a
    statute that it administers,” the district court tipped the scales in HHS’s
    favor. 28 Like the Administrator below, the district court analogized the
    Mississippi UCCP to state charity care days. Accordingly, the district court
    found that the UCCP patients were not “considered [Medicaid] beneficiaries”
    and not “eligible for benefits under a Section 1115 waiver.” It believed that the
    HHS approval letters’ text, program details/logistics, and different sources of
    funding all pointed to one conclusion: The UCCP was not part of any § 1115
    demonstration project.

    On appeal, the hospitals argue that the district court got it all wrong.
    The hospitals maintain that excluding the UCCP patient days runs contrary
    to statutory and regulatory directives that plainly require just the opposite.
    Moreover, the letters HHS sent to Mississippi approving payments under the
    § 1115 project establish that the UCCP patient days fall under the § 1115
    waiver’s authority.
    HHS agrees that the Secretary may “include patient days of patients not
    [eligible for Medicaid] but who are regarded as such because they receive
    benefits under a demonstration project.” 29 But HHS thinks UCCP patients
    didn’t receive benefits under a demonstration project.
    II. Discussion
    The rules governing jurisdiction and our standard of review are familiar.
    Jurisdiction. The district court had jurisdiction to review the Secretary’s
    final decision under Title XVIII of the Social Security Act. 30 And we have
    jurisdiction over the hospitals’ appeal under 28 U.S.C. § 1291.
    Standard of review. Our review of a summary-judgment grant is de novo,
    “applying the same standard as the district court.” 31 Under Rule 56, summary
    judgment is proper “if the movant shows that there is no genuine dispute as to
    any material fact and the movant is entitled to judgment as a matter of law.” 32
    A.     The DSH Statute and Regulation are Unambiguous, so HHS’s
    Interpretations are Owed No Deference under Chevron and Auer.
    HHS contends that its legal interpretations must be upheld under the
    Chevron and Auer judicial deference doctrines. We disagree. Judicial deference
    requires textual ambiguity, and here, the DSH statute and regulation
    29 42 U.S.C. § 1395ww(d)(5)(F)(vi)(II).

    unambiguously cut the hospitals’ way. There is no haziness—neither
    congressional nor administrative. And absent ambiguity, our ingenious design
    of constitutionally separated powers assigns the duty of interpreting the law
    to judges, not to regulators. 33
    1.     HHS’s statutory interpretation deserves no deference under
    Chevron.
    Under Chevron, a 35-year-old pillar of the administrative state, we defer
    to reasonable agency interpretations of ambiguous statutes “unless they are
    arbitrary, capricious, or manifestly contrary to the statute.” 34 But Chevron
    deference must be reflective, not reflexive. If statutory text is unambiguous,
    that’s that—no deference is due. The Constitution, after all, vests lawmaking
    power in Congress. 35 How much lawmaking power? “All,” declares the
    Constitution’s first substantive word. And Congress’s statutes define the scope
    of agencies’ power. Under bedrock separation-of-powers principles, Article III
    courts need not—indeed must not—outsource their constitutionally assigned
    interpretive duty to Article II agencies when the Article I Congress has spoken
    clearly. The integrity of our constitutional framework requires judges to fulfill
    “their duty as faithful guardians of the Constitution.” 36 Chief Justice Marshall
    was unsubtle: “It is emphatically the province and duty of the judicial
    department to say what the law is.” 37 The judiciary is a constitutional partner,
    but not a junior partner.
    33  “The interpretation of the laws is the proper and peculiar province of the courts.”

    Step One of Chevron analysis asks whether the statutory text is
    ambiguous. 38 If it is—and only if it is—courts then defer to agencies’ reasonable
    interpretations. 39 But if the statute is not ambiguous, then the agency’s
    interpretation gets no deference. 40
    In this case, we hold that the governing statutory text is clear, meaning
    HHS’s       interpretation      is    owed      no     Chevron       deference.       Section
    1395ww(d)(5)(F)(vi)(II) says to include days that a hospital treated patients
    eligible under a Medicaid-approved state plan in the Medicaid fraction’s
    numerator. And if the Secretary approves a demonstration project, then we
    regard patient days involving patients who “receive benefits under a
    demonstration project” as if they were patient days attributable to Medicaid-
    eligible patients (which means those days also go into the numerator). Put
    bluntly: Certain days just go into the Medicaid fraction’s numerator. Which
    days? Days that a hospital treated Medicaid-eligible patients or—if the
    Secretary approves a demonstration project—patients regarded as Medicaid
    eligible because of a demonstration project. This is binary: Patient days are
    either in or out. If patients underlying a given day were Medicaid-eligible or
    “receive[d] benefits under a demonstration project,” then that day goes into the
    numerator. Period. Otherwise, a patient day is out.
    Just as the statute’s mechanics are straightforward, so too are its words.
    The word “eligible” is generally construed to mean “capable of receiving.” 41 The
    statute also explains that a qualifying patient must either be (i) Medicaid-

    eligible or (ii) “regarded as such.” 42 According to the Oxford English Dictionary,
    “regarded” can mean “[t]o hold (a person) in (a specified degree of) esteem” or
    to “heed or take into account in determining action or conduct.” 43 In other
    words, the statute directs us to take certain patients “into account” in
    determining the fiscal intermediary’s “action or conduct”—calculating the
    Medicaid fraction—even though they aren’t actually Medicaid eligible. The
    statute explains that we are to “regard” such patients this way because they
    “receive benefits under a demonstration project.” 44 According to Black’s Law
    Dictionary, to “receive” means “[t]o take (something offered, given, sent, etc.);
    to come into possession of or get from some outside source .” 45 Additionally, Black’s Law Dictionary defines a “benefit” as the
    “advantage or privilege something gives; the helpful or useful effect something
    has.” 46 This means the fiscal intermediary must look to see who was capable of
    taking something offered (receiving); and that something offered must have
    had a helpful or useful effect (benefit). Finally, qualifying patients who are not
    actually Medicaid-eligible but are “regarded as such,” must “receive benefits
    under a demonstration project.” 47 The natural reading of “under” is “subject or
    pursuant to” or “by reason of the authority of.” 48
    When we piece all of this together as a cohesive whole, the statute means
    that patients who aren’t actually Medicaid-eligible still count towards the
    Medicaid fraction’s numerator if they’re considered or accounted to be capable

    Thus, the statute is unambiguous, and HHS’s contrary interpretation is

    Chevron deference (regarding ambiguous statutes) has a less-famous
    doctrinal cousin: Auer deference (regarding ambiguous regulations). Under
    Auer v. Robbins 49—currently under reconsideration at the Supreme Court 50—
    an agency’s interpretation of its own ambiguous regulation is generally
    controlling unless “plainly erroneous or inconsistent with the regulation.” 51
    While unanimous and initially uncontroversial, Auer has lost its luster over
    the years, weathering unsparing criticism from commentators 52 and jurists, 53

    for long, branding it one of the Court’s “worst decisions ever.” 54 Auer’s hours
    seem numbered.
    In practice, Auer deference mirrors Chevron deference. As with Chevron
    analysis, we first evaluate whether the regulation is ambiguous. 55 If it is, then
    we defer to HHS’s interpretation. But if the regulation’s plain language is
    unambiguous, HHS’s interpretation is entitled to no deference. 56
    In this case, the regulation, like the statute, is unambiguous, making
    Auer deference inappropriate. Recall the language of 42 C.F.R. § 412.106(b)(4):
    (4) Second computation. The fiscal intermediary determines . . .
    the number of the hospital’s patient days of service for which
    patients were eligible for Medicaid but not entitled to [Medicare],
    and divides that number by the total number of patient days in the
    same period. For purposes of this second computation, the
    following requirements apply:
    (i) For purposes of [the DSH numerator] computation, a patient is
    deemed eligible for Medicaid on a given day only if the patient is
    eligible for inpatient hospital services under an approved State
    Medicaid plan or under a waiver authorized under section
    1115(a)(2) of the Act on that day, regardless of whether particular
    items or services were covered or paid under the State plan or the
    authorized waiver.
    (ii) . . . hospitals may include all days attributable to populations
    eligible for [Medicaid] matching payments through a waiver

    For the reasons below, we believe that § 412.106(b)’s requirements are clear.
    And where regulatory language is clear, we do not look beyond that language. 58
    The regulation describes the pool of qualifying hospital patient days.
    That pool includes not only those “days of service for which patients were
    eligible for Medicaid,” 59 but also days of service in which a patient “is eligible
    for inpatient hospital services . . . under a waiver authorized under section
    1115(a)(2) . . . regardless of whether particular items or services were covered
    or paid under the State plan or the authorized waiver.” 60 It’s important to point
    out that section (i) begins by explaining which patients are “deemed eligible for
    Medicaid” for the purpose of computing the Medicaid fraction. This phrase
    equates patient days involving Medicaid-eligible patients—days the previous
    paragraph expressly includes in the Medicaid fraction—with patient days
    involving patients who, while not strictly eligible for Medicaid, receive
    healthcare coverage under similarly comprehensive state-authorized plans
    (plans that include inpatient hospital service benefits). 61 Plus, when read as a
    whole, section (i) indicates that a patient’s Medicaid eligibility “on a given day”
    is what’s germane. That’s what the fiscal intermediary has to figure out. What
    does not matter for purposes of this regulation is what the plan documents say
    about eligibility for particular services.
    Just as we saw in the DSH adjustment statute, the word “eligible” is a
    crucial word in this regulation—this whole regulation is about how the fiscal
    intermediary determines who’s “eligible for Medicaid” and, thus, counts

    towards the Medicaid fraction’s numerator. 62 Again, this is equivalent to
    figuring out who is “capable of receiving” something. 63 Likewise, the word
    “under,” which plays a big role in the statutory text, does the same in the
    regulation: A qualifying patient must be “eligible for inpatient hospital services
    under” a state Medicaid plan or approved waiver. 64 Since the natural reading
    of “under” is “subject or pursuant to” or “by reason of the authority of,” 65 when
    the fiscal intermediary sits down to figure out which patients are deemed
    eligible for Medicaid on a given day (for purposes of the Medicaid fraction), the
    phrase “eligible for inpatient hospital services . . . under a waiver authorized
    under section 1115(a)(2)” plainly describes those individuals who were capable
    of receiving inpatient hospital services pursuant to the project the Secretary
    approved in the § 1115(a)(2) waiver. 66
    In short, the DSH adjustment regulation is unambiguous, meaning HHS
    is entitled to no Auer deference.
    B.     The Unambiguous DSH Adjustment Statute and Regulation Favor the
    Hospitals.
    HHS spends almost 100% of its briefing explaining why the UCCP just
    wasn’t part of a § 1115 demonstration project. First, HHS argues, its
    September and March letters to Mississippi demonstrate that the UCCP was
    entirely separate from the § 1115 demonstration project. Second, courts have
    consistently held that state-only general assistance days and charity
    care/uncompensated care days are not “eligible for medical assistance under a

    State plan approved under [Medicaid].” 67 The UCCP days are like those days;
    those days don’t belong in the Medicaid fraction; therefore, UCCP days don’t
    belong in the Medicaid fraction.
    We disagree with both arguments. The UCCP was clearly part of the
    § 1115 project, and the cases HHS cites deal only with 42 U.S.C.
    § 1395ww(d)(5)(F)(vi)(II)’s first phrase, not the following “regarded as such”
    phrase. Accordingly, they’re easily distinguishable. Instead, we hold that this
    case’s facts are more akin to those in HealthAlliance Hospitals, Inc. v. Azar,
    where the district court of Washington, D.C. held that patient days under the
    Massachusetts Commonwealth Care program counted towards the DSH
    numerator. 68
    1.     HHS’s letters to Mississippi do not bolster HHS’s case.
    The fiscal intermediary must ascertain who’s “eligible for inpatient
    hospital services under an approved State Medicaid plan or under a waiver
    authorized under section 1115(a)(2).” 69 But HHS’s letters aren’t the slam dunk
    it thinks they are. For instance, the district court focused on the words “[i]n
    addition” in the September letter. But this was simply the transition phrase
    the letter used as it went from discussing the Medicaid demonstration (Project
    Number 11–W–00197/4) and SCHIP demonstration (Project Number 21–W–
    00023/4) to discussing the UCCP. Plus, the very next paragraph—the
    paragraph immediately after the UCCP paragraph—begins: “Our approval of
    this demonstration,” (singular) signaling that either (i) the UCCP is itself a
    demonstration or (ii) that the UCCP, Medicaid, and SCHIP programs together

    are considered to be a single demonstration. In any event, the letter’s
    introductory phrase, “[i]n addition,” doesn’t show that the UCCP wasn’t part
    of the approved demonstration project.
    The district court also thought that because the Medicaid and SCHIP
    programs had different start and end dates than the UCCP, the UCCP was a
    separate undertaking that was totally distinct from the demonstration project.
    This was wrong. Each piece of a demonstration project doesn’t have to work
    the same way or last for the same period of time. Indeed, given that each piece
    served a different function, it isn’t surprising that they began and ended on
    different days.
    The district court observed that the Secretary determined (as evidenced
    in the 2005 and 2006 letters) that individuals participating in the Medicaid
    expansion waiver “are presumed to be otherwise eligible for Medicaid or
    SCHIP in their respective home State,” while no such presumptions were made
    about the UCCP folks. This simply isn’t germane to the governing statute or
    regulation. The statutory and regulatory texts only care about whether
    patients underlying particular days were in fact eligible or regarded as eligible
    for Medicaid—there’s no textually grounded reason to consider what patients
    were presumed to be otherwise eligible for. 70 The district court erred when it
    focused on counterfactual eligibility.
    HHS also argues that it can exclude UCCP days from the Medicaid
    fraction’s numerator because the statute says that “the Secretary may, to the
    extent and for the period the Secretary determines appropriate, include patient
    days of patients not so eligible but who are regarded as such because they
    receive benefits under a demonstration project.” 71 This is true, but not quite on
    70   42 C.F.R. § 412.106(b)(4)(i).
    71   42 U.S.C. § 1395ww(d)(5)(F)(vi)(II) (emphasis added).

    point. The Secretary may exercise discretion, and the Secretary did exercise
    that discretion when he authorized the UCCP in the 2005 and 2006 letters.
    But the hospitals’ argument is more convincing: Once the Secretary authorizes
    a demonstration project, no take-backs. The statutory discretion isn’t
    discretion to exclude populations that the Secretary has already authorized
    and approved for a given period; it’s discretion to authorize the inclusion of
    those populations in the first place.
    2.     Cases interpreting 42 U.S.C. § 1395ww(d)(5)(F)(vi)(II) do not help
    HHS.
    As mentioned above, HHS directs our attention to various cases dealing
    with 42 U.S.C. § 1395ww(d)(5)(F)(vi)(II)’s phrase, “eligible for medical
    assistance under a State plan approved under [Medicaid].” 72 But these cases
    deal only with subsection (II)’s first phrase. They don’t shed any light on
    subsection (II)’s second phrase, the phrase that governs this case: “patient days
    of patients not so eligible but who are regarded as such because they receive
    benefits under a demonstration project.” 73 Since the cases HHS cites don’t deal
    with programs authorized under a demonstration project, they’re irrelevant to
    determining whether Mississippi’s UCCP days belong in the Medicaid
    fraction’s numerator. 74

    We do, however, find Judge Ketanji Brown Jackson’s excellent opinion
    in HealthAlliance Hospitals, Inc. v. Azar extremely persuasive. 75 That opinion
    clearly and convincingly explains why the law governing the inclusion of § 1115
    waiver patient days in the Medicaid fraction is straightforward: The plain
    regulatory text demands that such days be included—period. 76
    3.     Per clear statutory and regulatory directive, the UCCP days belong in
    the Medicaid fraction’s numerator.
    HHS argues that “no patient received benefits under the UCCP.” This
    statement is mystifying. If UCCP patients didn’t receive benefits under the
    UCCP, what did they receive? And under what or whose authority did they
    receive, well, whatever non-benefits they received? Medical assistance is a
    benefit. 77 And medical assistance is precisely what UCCP patients got. Plus, if
    the UCCP wasn’t established under authority of a demonstration project, then
    by whose or what authority was it established? It certainly wasn’t part of a
    typical “state plan” that followed the normal HHS approval process outlined in
    42 U.S.C. § 1396a. HHS’s theory—that the UCCP patients did not receive
    benefits under a § 1115 demonstration—offers no satisfactory answers to these
    questions.
    This Hurricane Katrina demonstration project encompassed the UCCP.
    So, the only question the fiscal intermediary would need to answer when
    counting patient days associated with an approved demonstration project
    under the relevant DSH adjustment regulation is whether UCCP patients
    were capable of receiving inpatient health services. They were. Accordingly,
    the fiscal intermediary should’ve included UCCP days.

    III. Conclusion
    Generalist judges are not policy experts. That said, interpreting the laws
    under which Americans live is a quintessentially judicial function. And when
    legal texts are unambiguous, as these are, courts should stand firm and decide,
    not tiptoe lightly and defer.
    For the reasons discussed above, we hold that HHS’s decision to exclude
    UCCP patient days from the Medicaid fraction’s numerator is “not in
    accordance with law.” 78 Accordingly, we REVERSE and REMAND to the
    Medicaid Administrative Contractor to include the UCCP days in the hospitals’
    DSH adjustment.
