    Appeal from the United States District Court
    for the Eastern District of Wisconsin.
    No. 98-C-0553--Rudolph T. Randa, Judge.
    Argued April 12, 2001--Decided June 5, 2001
    Before Flaum, Chief Judge, and Manion and
    Kanne, Circuit Judges.
    Flaum, Chief Judge. Plaintiff Paragon
    Health Network, Inc. ("Paragon")/1
    appeals from a district court decision
    affirming a determination that its newly
    opened skilled nursing facility ("SNF"),
    Milwaukee Subacute Center ("MSC"), is not
    eligible for an exemption from the
    routine cost limits ("RCLs") of Medicare.
    Paragon contends that the interpretations
    by the Secretary of Health and Human
    Services ("Secretary") of the relevant
    regulation are arbitrary and unreasonable
    and that the decision denying an
    exemption to MSC is not supported by
    substantial evidence. For the reasons
    stated herein, we affirm.
    I.   Background
    Wisconsin has adopted a set of statutes
    regulating nursing facilities. Wis. Stat.
    sec. 150.21, et seq. Wisconsin requires
    each SNF to have Certificate of Need
    ("CON") rights for the beds it operates.
    The state has a moratorium on the
    issuance of new CON rights; thus, to open
    a SNF, one must obtain CON rights from a
    currently existing nursing provider.
    Wisconsin permits the transfer of CON
    rights, but only to a related entity that
    will operate within the same Health
    Service Area ("HSA") as the current owner
    of the rights. The state is split into
    eight HSAs.
    Paragon opened MSC as a SNF in downtown
    Milwaukee, Wisconsin on April 7, 1995,
    with a capacity of thirty-five nursing
    beds. MSC obtained the rights to these
    thirty-five beds from Shores Transitional
    Care and Rehabilitation Center
    ("Shores"), another facility owned by
    Paragon. Shores is located in Glendale, a
    northern suburb of Milwaukee, and the
    distance between the two facilities is
    about seven miles. Both MSC and Shores
    are located in HSA Number Two, which is
    approximately eighty miles long, forty to
    fifty miles wide, and encompasses the
    city of Milwaukee and seven counties. At
    the time immediately before the transfer,
    Shores had CON rights to four-hundred-
    and-three beds. Shores continues to
    operate as a separate facility after the
    transfer of a fraction of its CON rights
    to MSC. The only thing that MSC received
    from Shores were the CON rights; no
    residents, staff, or equipment were
    transferred.
    The RCLs are the maximum amount that the
    federal government will pay for services
    under the Medicare program. See generally
    Good Samaritan Hosp. v. Shalala, 
    508 U.S. 402
    , 404-06 (1993) (providing a "rough
    description" of the RCL regime). At the
    time when MSC opened, 42 C.F.R. sec.
    413.30(e) exempted "new providers" from
    the RCLs for a period of up to two years.
    MSC applied for this exemption on June
    20, 1995, but the Health Care Financing
    Administration ("HCFA"), the federal
    agency through which the Secretary
    administers the Medicare program, denied
    this request. Paragon appealed to the
    Provider Reimbursement Review Board
    ("PRRB"), which conducted an evidentiary
    hearing and concluded that MSC was not
    entitled to the new provider exemption.
    The PRRB found that MSC was a relocated
    portion of Shores rather than a new
    facility, relying only on the transfer of
    CON rights from Shores to MSC in reaching
    this conclusion. The PRRB also considered
    whether MSC would be granted the new
    provider exemption as a relocated
    provider serving a substantially
    different inpatient population. The PRRB
    stated that MSC could not qualify for the
    exemption in this manner either because
    MSC’s patients came from the same cities
    and towns as Shores, which is to say that
    almost all of the patients of both
    facilities live in Milwaukee. The HCFA
    Administrator declined to review the
    adjudication, and so the PRRB’s decision
    became the final decision of the
    Secretary. 42 U.S.C. sec. 1395oo(f)(1).
    Paragon filed suit in district court
    claiming that the PRRB’s decision
    unreasonably interpreted 42 C.F.R. sec.
    413.30(e) and was not supported by
    substantial evidence, but the court
    rejected Paragon’s arguments and entered
    summary judgment in favor of the
    Secretary.
    II.    Discussion
    A.    Standard of Review
    42 U.S.C. sec. 1395oo(f)(1) states that
    we review the Secretary’s decision under
    the Administrative Procedure Act. Thus,
    we will reverse the Secretary’s
    determination only if it is arbitrary,
    capricious, not supported by substantial
    evidence, or otherwise deficient under
    the standards set forth in 5 U.S.C. sec.
    706. In addition, we normally defer to
    the Secretary’s reasonable construction
    of the Medicare regulations. See Thomas
    Jefferson Univ. v. Shalala, 
    512 U.S. 504
    ,
    512 (1994). We first consider whether the
    regulation is ambiguous. See Christensen
    v. Harris County, 
    529 U.S. 576
    , 588
    (2000). If not, then we apply the
    regulation according to its plain
    meaning; if so, then the Secretary’s
    interpretation is entitled to
    "controlling weight unless it is plainly
    erroneous or inconsistent with the
    regulation." Thomas 
    Jefferson, 512 U.S. at 512
    (internal quotation marks
    omitted); see also Bowles v. Seminole
    Rock & Sand Co., 
    325 U.S. 410
    , 414
    (1945).
    B.    Secretary’s Interpretation
    42 C.F.R. sec. 413.30(e) contains an
    exemption to the Medicare RCLs for a "new
    provider." A new provider is defined as
    "a provider of inpatient services that
    has operated as the type of provider (or
    the equivalent) for which it is certified
    for Medicare, under present and previous
    ownership, for less than three full
    years."/2 The Provider Reimbursement
    Manual ("PRM"), a set of instructions
    issued by the Secretary that constitutes
    an administrative interpretation of the
    Medicare statute and regulations, see
    Shalala v. Guernsey Mem’l Hosp., 
    514 U.S. 87
    , 101-02 (1995) (referring to PRM
    provisions as interpretive rules),
    provides further guidance on new provider
    exemptions. PRM sec. 2604.1 reiterates
    the definition of new provider contained
    in the regulation, and then states that a
    provider which relocates could be granted
    new provider status if it meets certain
    conditions./3
    In denying that MSC was a new provider,
    the PRRB relied solely on the fact that
    MSC had acquired CON rights from Shores.
    In determining the length of time a
    provider has "operated," the Secretary
    considers the "previous ownership" of the
    SNF’s CON rights. The operating history
    of the SNF from which any CON rights were
    obtained is imputed to the acquiring
    provider. In the instant case, this
    interpretation caused the PRRB to
    conclude that MSC had been operating
    since 1979, the year Shores opened, since
    MSC and Shores provide the same type of
    service. Instead of MSC being a new
    provider, the PRRB decided that MSC was a
    relocated part of Shores.
    C. New Provider
    1. Challenges to Seminole Rock
    deference.
    Paragon has a number of arguments as to
    why the Secretary’s interpretation is
    incorrect, but the contentions we will
    initially consider regard the weight that
    should be given to the Secretary’s
    construction of 42 C.F.R. sec. 413.30(e).
    Paragon claims that the deference
    normally accorded agency interpretations
    of their own regulations is warranted
    only where the interpretation is both
    contemporaneous with the regulation and
    consistently applied. Appellant claims
    that the contemporaneity requirement for
    deference is not satisfied here because
    the Secretary’s interpretation relying
    solely on the transfer of CON rights to
    deny that a SNF is a new provider was not
    made until 1995, while the regulation was
    promulgated in 1979. Paragon also
    contends that the interpretation has not
    been consistent, relying on PRM sec.
    2154.2.C., which defines "relocate" as
    "[t]o move an existing provider to a new
    location and close the old provider."
    Paragon claims that this is the only
    definition of "relocate" in the PRM, and
    so should be applied whenever that word
    appears in the Medicare statute,
    regulations, or PRM provisions. Paragon
    seizes upon the last part of this
    definition to argue that MSC cannot be a
    relocated provider since the old
    provider, Shores, has not closed. Thus,
    the PRRB was inconsistent in labeling MSC
    as a relocated provider since this
    decision ignored the definition of
    "relocate" contained in the PRM.
    The Secretary claims that the current
    interpretation of 42 C.F.R. sec.
    413.30(e) is not new, but does not cite
    any decision construing that regulation
    in the manner at issue here until 1995.
    The Secretary also cites a number of
    post-1995 PRRB decisions that have
    consistently applied the proffered
    interpretation. Appellee claims that the
    definition of "relocate" contained in PRM
    sec. 2154.2.C. has never been applied to
    new provider exemptions and concerns a
    completely different subject. HCFA has
    long recognized the concept of a partial
    relocation in applying new provider
    exemptions from the RCLs.
    Before we address the legal issues, we
    set forth the history of the
    interpretation of 42 C.F.R. sec.
    413.30(e) as best we can determine from
    the submissions of both parties. That
    regulation has been given the same
    consistent interpretation since 1995, but
    neither party has provided evidence of
    any construction prior to that time.
    Thus, we assume that the regulation was
    first authoritatively construed in 1995.
    We also accept that the definition of
    "relocate" contained in PRM sec.
    2154.2.C. has not been applied to the
    regulations concerning exemptions and the
    concept of a partial relocation has been
    recognized by HCFA.
    We first conclude that the apparent lack
    of contemporaneity between the
    promulgation of the regulation and the
    Secretary’s interpretation of it does not
    affect the high level of deference we owe
    to the Secretary. In the context of
    judicial deference to agency
    interpretations of administrative
    statutes under Chevron, U.S.A., Inc. v.
    Natural Resources Defense Council, Inc.,
    
    467 U.S. 837
    (1984), an agency
    construction formulated well after the
    statute’s enactment is still entitled to
    deference. See Smiley v. Citibank (South
    Dakota), N.A., 
    517 U.S. 735
    , 740-41
    (1995). Smiley explained that the
    rationale of Chevron is a presumption
    that Congress intended for ambiguities in
    a statute primarily to be resolved by the
    agency charged with administering that
    statute, and so deference is warranted
    regardless of whether the agency
    officials interpreting the law have any
    special knowledge of Congress’s specific
    intentions at the time the statute was
    passed. 
    Id. The rationale
    for Seminole
    Rock deference is similar to that for
    Chevron. Martin v. Occupational Safety &
    Health Review Commission, 
    499 U.S. 144
    ,
    151 (1991) explains that regulatory
    deference is justified by the presumption
    that the power to authoritatively
    interpret the agency’s own regulations is
    part of the lawmaking powers delegated by
    Congress. Thus, just as with Chevron,
    deference to regulatory interpretations
    does not depend on contemporaneity, since
    no demonstration that the agency
    officials had special insight into the
    intentions behind the passage of the
    regulation is required. Instead, Congress
    is presumed to have delegated the primary
    power to fill regulatory ambiguities to
    the agency, and courts owe deference to
    agency decisions that clarify a
    regulation regardless of the fact that
    the agency waited to exercise this power.
    Moving on to the consistency question,
    we initially note that Paragon is not
    arguing that the Secretary has in the
    past used the PRM sec. 2154.2.C.
    definition of "relocate" in new provider
    determinations under 42 C.F.R. sec.
    413.30(e) and PRM sec. 2604.1, but now
    refuses to do so. A HCFA witness at the
    PRRB hearing stated that HCFA had always
    recognized the concept of partial
    relocations, where the original provider
    does not close its doors, and Paragon has
    not brought forth any evidence to contest
    that assertion. Rather, Paragon contends
    that HCFA and the PRRB should have used
    the PRM sec. 2154.2.C. in making new
    provider determinations, contrary to the
    actual practice. Paragon relies on the
    canon that "identical words used in
    different parts of the same act are
    intended to have the same meaning,"
    Commissioner v. Keystone Consol. Indus.,
    Inc., 
    508 U.S. 152
    , 159 (1993) (internal
    quotation marks omitted), to argue that
    the definition in PRM sec. 2154.2.C.
    should be applied to new provider
    determinations under PRM sec. 2604.1.
    The PRM, while a useful guide to
    interpreting the Medicare statute and
    regulations, is not strictly binding on
    the Secretary; we will uphold a decision
    despite certain variations from the
    manual. See Howard Young Med. Ctr. Inc.
    v. Shalala, 
    207 F.3d 437
    , 442-43 (7th
    Cir. 2000); Adventist Living Ctrs., Inc.
    v. Bowen, 
    881 F.2d 1417
    , 1423-24 & n.10
    (7th Cir. 1989). Thus, Paragon’s argument
    that the Secretary is required to use the
    PRM definition has less weight than if
    that definition appeared in the Medicare
    statutes or regulations. Moreover, the
    canon Paragon relies on has reduced force
    when the identical word is used in
    different provisions which address
    disparate subjects. See Atlantic Cleaners
    & Dyers, Inc. v. United States, 
    286 U.S. 427
    , 433 (1932); see also United States
    v. Cleveland Indians Baseball Co., 121 S.
    Ct. 1433, 1441 (2001). PRM sec. 2154.2.C.
    is contained in a section of the PRM
    discussing when planning costs will be
    incorporated into the historical cost of
    a facility, while the issue in this case
    is exemptions from the RCLs for new
    providers, which is discussed in a wholly
    different chapter of the PRM. As noted
    above, the Secretary has consistently
    labeled a transfer of less than an entire
    facility as a partial relocation for
    purposes of the new provider exemption.
    Given all of these circumstances, we find
    nothing untoward in the Secretary’s
    declining to rely on the definition of
    "relocate" in PRM sec. 2154.2.C. in
    making new provider determinations under
    42 C.F.R. sec. 413.30(e) and PRM sec.
    2604.1. Thus, we conclude that Seminole
    Rock deference is owed to the Secretary’s
    interpretation of 42 C.F.R. sec.
    413.30(e) despite the lack of
    contemporaneity and refusal to apply PRM
    sec. 2154.2.C./4
    2.   Ambiguity.
    Having found that Seminole Rock
    deference is warranted, we next determine
    whether 42 C.F.R. sec. 413.30(e) is
    ambiguous. Paragon argues that the
    regulation has a plain meaning, which is
    contradicted by the Secretary’s
    interpretation. Paragon focuses on the
    phrase "provider of inpatient services
    that has operated" in the regulation and
    its relation to "present and previous
    ownership." According to the appellant,
    the question of ownership must be decided
    with respect to the "provider" as a
    whole. A "provider" consists of all those
    attributes necessary for a SNF to
    "operate[ ]"-- that is, not just CON
    rights, but physical beds, employees,
    administrators, equipment, patients,
    referral sources, etc. Paragon backs this
    up with a citation to PRM sec. 2604.1,
    which states that a "new provider is an
    institution that has operated . . . ."
    Paragon claims that the use of the word
    "institution" in the PRM underscores the
    fact that "provider" in 42 C.F.R. sec.
    413.30(e) refers to the facility as a
    whole, rather than just CON rights. Thus,
    only when the SNF as an entire operating
    institution is transferred to a new owner
    can the exemption for a new provider be
    denied.
    Despite Paragon’s arguments, we conclude
    that the regulation is ambiguous on what
    constitutes a "provider." Paragon is
    correct that a nursing "provider" is
    composed of many different attributes,
    but changing one or more of these
    characteristics does not mean that the
    SNF becomes a different "provider." For
    example, if a facility fires all its
    staff and hires a new one, but makes no
    other changes, an ordinary user of the
    English language probably would consider
    the SNF with the new staff to be the same
    "provider" as it was before. Similarly, a
    SNF that replaced all of its old
    equipment with new models would still be
    the same "provider" as it was before the
    modernization. Even if a SNF both fired
    its staff and replaced all of its
    equipment, one might still call it the
    same "provider" if the administration and
    physical plant remained the same. Of
    course, if all the various things that
    make up a SNF were new in the sense that
    they had not been part of another
    facility, then one would have to call
    that SNF a "new provider." Conversely, if
    a nursing facility did not change any of
    its aspects, it would unquestionably
    continue to be the same provider rather
    than a new one. The difficulty in drawing
    a line between these two extremes is what
    makes the word "provider" ambiguous as
    used in the regulation.
    3.   Reasonableness.
    Since the regulation is ambiguous, we
    next examine whether the Secretary’s
    interpretation is plainly erroneous or
    inconsistent with the text. We begin with
    what is basically an extension of
    Paragon’s argument for the clarity of the
    regulation’s language. Even if words like
    "provider" and "operate[ ]" are
    ambiguous, these must refer to more than
    just a provider’s CON rights. In
    determining whether a SNF operated "under
    . . . previous ownership," the Secretary
    should not rely on CON rights alone but
    also take account of whether the staff,
    referrals, equipment, etc. of the
    facility are the same as the one from
    which the CON rights were obtained.
    Paragon’s argument does have a degree of
    merit--terms like "operate[ ]" and
    "provider" suggest that one should look
    to whether a group of attributes making
    up the institution have changed such that
    the SNF may be described as new, rather
    than just focusing on a single
    characteristic, such as CON rights.
    Nevertheless, we conclude that the
    Secretary’s interpretation is not so much
    at variance with the language of the
    regulation as to be deemed plainly
    erroneous or inconsistent with the text.
    Medicare is a highly complex and
    technical program, and so deference to
    the Secretary’s determinations in the
    course of administering the system is
    especially warranted. Thomas 
    Jefferson, 512 U.S. at 512
    . Furthermore, an agency
    need not adopt the most natural reading
    of the regulation, but only a reasonable
    one. Pauley v. BethEnergy Mines, Inc.,
    
    501 U.S. 680
    , 702 (1991). The Secretary
    explains that a transfer of CON rights
    does not result in the provision of any
    new services. Even though the transferee
    might have new equipment, staff, etc., it
    will provide the same kind of services as
    the transferor of the CON rights, just at
    a different location. We cannot say that
    the Secretary’s interpretation that
    because no new services are being
    provided there is not a new provider is
    unreasonable.
    Paragon also has a few policy arguments
    as to why the Secretary’s construction of
    42 C.F.R. sec. 413.30(e) should be
    invalidated, but none of these are
    convincing. The first is that the purpose
    of the new provider exemption is "to
    allow a provider to recoup the higher
    costs normally resulting from low
    occupancy rates and start-up costs during
    the time it takes to build its patient
    population." San Diego Physicians &
    Surgeons Hosp. v. Aetna Life Ins. Co.,
    [1990-1991 Transfer Binder] Medicare &
    Medicaid Guide (CCH) para. 39,007, at
    25,061 (HCFA Administrator 1991). When
    MSC opened, it incurred large start-up
    costs and had a very low occupancy rate,
    resulting in high costs per patient. The
    receipt of CON rights from Shores did
    nothing to ameliorate these expenses.
    Thus, CON rights alone should not be used
    to deny that a SNF is a new provider
    since these rights have no relation to
    the purposes of the exemption.
    However, the Secretary has an adequate
    response to this argument. At the time in
    question, SNFs were reimbursed under
    Medicare the lesser of the reasonable
    cost of or the customary charge for the
    service in question./5 42 U.S.C. sec.
    1395f(b)(1) (1994). The definition of
    "reasonable cost" excludes any "cost
    found to be unnecessary in the efficient
    delivery of needed health services." 42
    U.S.C. sec. 1395x(v) (1)(A). The
    Secretary contends, as with the textual
    argument above, that the transfer of CON
    rights simply shifts around SNF services.
    Creating a new facility and moving
    services to it, as Paragon did between
    MSC and Shores, is costly, but no benefit
    is gained in the overall delivery of
    health services if the new facility is
    providing the same services to the same
    populace as the old one. Thus, the
    Secretary’s judgment that the high start-
    up costs of MSC were "unnecessary in the
    efficient delivery of needed health
    services" is a reasonable one that will
    not be disturbed by this court.
    Paragon’s next arguments focus upon the
    effect of making a new provider
    determination depend upon CON rights. The
    first is that several states do not have
    CON or similar programs, and that a HCFA
    witness at the PRRB hearing admitted that
    in such a state MSC would have been
    considered a new provider. To make a new
    provider determination depend solely on
    which state the SNF happens to be in is
    unreasonable and arbitrary. The second is
    that under the Secretary’s interpretation
    a new provider cannot exist in Wisconsin
    because the state has imposed a
    moratorium on issuing new CON rights. Any
    SNF that begins operations will have to
    obtain its CON rights from an already
    existing provider and have the transferor
    provider’s history imputed to it,
    preventing it from being a new provider
    under 42 C.F.R. sec. 413.30(e).
    We again find the Secretary’s responses
    to these arguments to be sufficiently
    convincing so as to prevent us from
    declaring the interpretation to be
    plainly erroneous. Regarding the first,
    the Secretary points out that a CON
    program provides benefits for SNFs. More
    specifically, institutions like MSC are
    insulated from the effects of competition
    with new entrants. This fact reduces the
    need for new SNFs to obtain extra funds
    from Medicare in order to stay afloat. As
    for the second argument, the Secretary
    can rely in part on the state’s
    determination that no new nursing
    facilities are needed to support a
    decision that additional beds are
    unnecessary to the efficient delivery of
    health care services in that state.
    Paragon complains that Wisconsin also ap
    proved the movement of beds from Shores
    to MSC, indicating that the state thought
    that the move was necessary to serve the
    area of inner-city Milwaukee. However,
    there is no evidence that Wisconsin’s
    approval of the transfer of beds was made
    under the strict standard imposed by 42
    U.S.C. sec. 1395x(v)(1)(A). Wisconsin
    might approve such relocations even
    though the cost is not necessary to the
    efficient delivery of health care. Thus,
    the Secretary could reasonably use
    Wisconsin’s decisions about the state’s
    need for nursing care to set an upper
    limit on the costs that are necessary for
    Medicare to bear, while denying
    reimbursement of costs in areas where the
    Secretary believes Wisconsin is too
    lenient.
    To summarize, the lack of the
    contemporaneity between the regulation’s
    promulgation and the adoption of the
    Secretary’s current construction does not
    eliminate the deference we owe to the
    Secretary. Likewise, this deference is
    also not affected by the Secretary’s
    decision to use a definition of
    "relocate" for the new provider exemption
    other than the one stated in the PRM for
    use on a different subject. The
    regulation is ambiguous, and the
    Secretary’s interpretation of the
    regulation is not plainly erroneous on
    either textual or policy grounds.
    D.   Relocated Provider
    The Secretary has interpreted the
    exemption for new providers in 42 C.F.R.
    sec. 413.30(e) to be available to certain
    relocated providers. PRM sec. 2604.1
    discusses when a relocated provider will
    be granted the status of a new provider,
    stating in part:
    [F]or purposes of this provision, a
    provider which relocates may be granted
    new provider status where the normal
    inpatient population can no longer be
    expected to be served at the new
    location. The distance moved from the old
    location will be considered but will not
    be the determining factor in granting new
    provider status. For example, a specialty
    hospital may move a considerable distance
    and still care for generally the same
    inpatient population, while the
    relocation of a general hospital a
    relatively short distance within a
    metropolitan area may greatly affect the
    inpatient population served. A provider
    seeking such new provider status must
    apply to the intermediary and demonstrate
    that in the new location a substantially
    different inpatient population is being
    served.
    MSC’s request for new provider status
    based on its relocation was denied by the
    PRRB. In interpreting the phrase
    "substantially different inpatient
    population," the PRRB applies a "same
    cities and towns" standard: if the
    relocated provider’s current patients
    came from the same cities and towns as at
    its old location, then the exemption will
    be denied. The vast majority of patients
    for both MSC, the relocated provider, and
    Shores, the original location, come from
    the city of Milwaukee, and thus the PRRB
    denied the exemption.
    1.   Retroactivity.
    Paragon’s first challenge is that the
    PRRB’s decision retroactively applied a
    new rule, violating Bowen v. Georgetown
    University Hospital, 
    488 U.S. 204
    (1988).
    Paragon claims that current PRM sec.
    2533.1.B.3, which did not come into
    effect until after MSC’s application for
    the new provider exemption, was used to
    dispose of its request. PRM sec.
    2533.1.B.3 states that the new provider
    exemption may be granted to a relocated
    provider only if the SNF relocates to a
    different state-defined HSA. Paragon
    relies primarily on the fact that a HCFA
    witness at the PRRB hearing admitted that
    the agency applied this new standard in
    rejecting MSC’s application.
    However, the evidence does not support
    Paragon’s position. What the HCFA witness
    said is irrelevant to our review, since
    the PRRB’s adjudication stands as the
    final decision of the Secretary under 42
    U.S.C. sec. 1395oo(f)(1). The PRRB simply
    did not apply the standard contained in
    PRM sec. 2533.1.B.3. The PRRB’s
    discussion of MSC’s request for new
    provider status as a relocated provider
    never mentions the fact that Shores and
    MSC are both located in HSA Number Two.
    Instead, the opinion relies on the fact
    that "practically 100 percent" of MSC’s
    admissions come from the same cities and
    towns as Shores’ admissions. Thus, the
    PRRB did not retroactively apply PRM sec.
    2533.1.B.3.
    2.   Arbitrary and capricious.
    Paragon’s next argument is that the
    same-cities-and-towns standard is
    arbitrary and capricious since it contra
    dicts the language of PRM sec. 2604.1.
    That PRM section states that relocation
    "a relatively short distance within a
    metropolitan area" can be sufficient for
    new provider status. Paragon claims that
    the same-cities-and-towns standard means
    that a provider that moves within a
    metropolitan area cannot qualify for new
    provider status, contradicting this
    portion of the PRM’s text.
    We reject Paragon’s textual argument. A
    metropolitan area can contain many
    different municipal corporations. If a
    provider primarily serving one town
    relocates within the same metropolitan
    area to a different town and begins to
    serve mostly residents of the new town,
    then that relocated provider could attain
    new provider status under the Secretary’s
    interpretation of PRM sec. 2604.1. Thus,
    there is no contradiction between stating
    that movement within a metropolitan area
    can be sufficient for granting new
    provider status while also dictating that
    the new location must serve patients from
    different cities and towns than the old
    location.
    Paragon also argues that the same-
    cities-and-towns standard is arbitrary
    since it does not take account of the
    fact that such incorporated areas can
    vary widely in size. That the standard
    applied by the PRRB treats disparately
    sized towns and cities the same is true,
    but agencies are permitted to rely on
    broad categorizations that may not
    perfectly reflect the underlying facts.
    Cf. Heckler v. Campbell, 
    461 U.S. 458
    ,
    467-68 (1983) (holding that using
    guidelines rather than a completely
    individualized inquiry to determine what
    kinds of jobs a disabled person can
    perform is not arbitrary or capricious).
    The same-cities-and-towns standard has a
    reasonable connection to determining
    whether a substantially different
    inpatient population is being served by a
    relocated provider, and is more efficient
    and less costly than a more detailed
    method.
    3.   Substantial evidence.
    Paragon’s next argument is that the
    PRRB’s decision is not supported by
    substantial evidence. Paragon cites
    patient referral and zip code data to
    support its claim that MSC was serving a
    substantially different inpatient
    population from Shores’. Paragon’s
    contention here seems to be premised on
    the same-cities-and-towns standard being
    invalid. However, we have already upheld
    that standard, and so the only question
    for purposes of substantial evidence is
    whether MSC’s patients came from the same
    cities and towns as Shores’. The PRRB
    found that patients for both facilities
    came overwhelmingly from Milwaukee, and
    Paragon has not challenged this finding.
    Therefore, the PRRB’s decision is
    supported by substantial evidence.
    III.   Conclusion
    Seminole Rock deference is owed to the
    Secretary’s construction of 42 C.F.R.
    sec. 413.30(e). Relying on the operating
    history of the transferor of CON rights
    to deny the new provider exemption to the
    transferee is not plainly erroneous.
    Using the same-cities-and-towns standard
    to find that a relocated SNF is not
    serving a substantially different
    inpatient population is not arbitrary or
    capricious. Since the Secretary’s
    interpretations are reasonable, we Affirm
    the district court’s decision upholding
    the PRRB’s decision denying new provider
    status to MSC.

    /2 After MSC’s request, the language defining a new
    provider was modified by replacing "provider"
    with "SNF" and moved to 42 C.F.R. sec. 413.30(d).
    We will refer to the language and location of the
    older version in effect when MSC applied for the
    exemption.
    /3 PRM sec. 2604.1 was removed from the manual after
    MSC applied for its exemption and has been re-
    placed by PRM sec. 2533, which is substantially
    different, as partially described below in Part
    D.1.
    /4 We wish to make clear that, for the reasons
    provided in the preceding discussion, we find
    that the Secretary has consistently interpreted
    42 C.F.R. sec. 413.30(e) and did not reverse a
    prior interpretation in denying MSC’s request. If
    the parties’ submissions had demonstrated that
    the Secretary had in fact reversed course, we
    would be confronted with a different case pre-
    senting a number of issues we need not address.
    For example, in such circumstances, the interpre-
    tive change could be considered arbitrary and
    capricious if it "does not take account of legit-
    imate reliance on [the] prior interpretation."

    opened prior to HCFA’s 1995 decisions establish-
    ing the interpretation at issue here, the Sec-
    retary’s current interpretation could have been
    impermissibly retroactive if MSC would have been
