    *   Of the District of Rhode Island, sitting by designation.
    December 19, 2022
    SELYA, Circuit Judge.        In this case, the plaintiff
    brought a wrongful death action in state court. He alleged medical
    malpractice against (inter alia) a physician who worked for a
    federally funded health center.           The patient (the plaintiff's
    decedent) was unaffiliated with the health center.              The United
    States removed the action to federal court and sought to substitute
    itself as a defendant in the physician's place and stead.                 To
    justify removal and substitution, the United States invited the
    district court to invoke the provisions of the Federal Employees
    Liability Reform and Tort Compensation Act of 1988 (the Westfall
    Act),   
    28 U.S.C. § 2679
    .     The    district     court   accepted   the
    government's invitation, invoked the Westfall Act, substituted the
    United States for the physician, and subsequently granted the
    government's motion to dismiss the plaintiff's amended complaint
    for failure to state a claim upon which relief could be granted.
    The plaintiff appealed.      In this court, the government
    conceded it had led the district court into a dead end:                   it
    repudiated its earlier reliance on the Westfall Act and, instead,
    attempted to salvage the substitution order under a provision of
    the Public Health Service Act (PHSA), 
    42 U.S.C. § 233
    .           This shift
    in direction brought new issues into play and left gaps in the
    evidentiary    record.    Those   gaps    must   be    filled   by   further
    proceedings in the district court, which can then resolve the new
    issues that have emerged as a result of the government's about-
    - 3 -
    face.     We therefore vacate the substitution order, vacate the
    partial final judgment entered below, and remand to the district
    court for further proceedings consistent with this opinion.
    I
    We begin with the relevant facts.       Because this appeal
    follows the allowance of a motion to dismiss under Federal Rule of
    Civil Procedure 12(b)(6), we draw those facts from the plaintiff's
    amended complaint and other materials in the record that may be
    considered at the motion-to-dismiss stage.         See Aguilar v. U.S.
    Immigr. & Customs Enf't, 
    510 F.3d 1
    , 8 (1st Cir. 2007); Banco
    Santander de P.R. v. Lopez-Stubbe (In re Colonial Mortg. Bankers
    Corp.), 
    324 F.3d 12
    , 14-16 (1st Cir. 2003); Beddall v. State St.
    Bank & Tr. Co., 
    137 F.3d 12
    , 17 (1st Cir. 1998).
    A
    Plaintiff-appellant    Brad   O'Brien    is   the   surviving
    partner of Melissa Allen and the personal representative of her
    estate.    The sequence of events leading up to Allen's demise is
    largely undisputed.     On July 26, 2016, Allen suffered multiple
    seizures at her home.   She was brought to Lowell General Hospital
    (the Hospital) in Lowell, Massachusetts, and admitted at 5:00 a.m.
    There, emergency department staff found that Allen was seven months
    pregnant and suffering from severe hypertension.1         Dr. Fernando
    1 According to the undisputed facts, neither Allen nor anyone
    else had known of her pregnancy until then.
    - 4 -
    Roca, an obstetrician who was present in the Hospital, was summoned
    to consult.   At 5:22 a.m., Allen was transferred to the labor and
    delivery unit, where Dr. Roca oversaw her care. While there, Allen
    suffered another seizure.   At 6:54 a.m., Dr. Roca decided that it
    was necessary to perform a cesarean section, and a baby girl was
    delivered approximately ten minutes later.
    Following the birth of her baby, Allen was moved to the
    intensive care unit.    By that time, she was unresponsive, her
    pupils were unequal and non-reactive, and she had no reflexes.    A
    brain scan revealed "devastating neurological injury."     Allen was
    then flown by helicopter to a tertiary care hospital in Boston,
    where she died eleven days later.    The causes of death were listed
    as "intracranial hemorrhage and eclampsia."
    B
    Inasmuch as this case started with a state-court suit
    against Dr. Roca, we add some context about his involvement.   Even
    though he provided care to Allen at the Hospital, Dr. Roca worked
    for Lowell Community Health Center (the Health Center), an entity
    that receives federal grant funds under 42 U.S.C. § 254b.
    As of a date no later than January 1, 2015, the Health
    Center was deemed to be a Public Health Service (PHS) "employee"
    for purposes of 
    42 U.S.C. § 233
    .     Its "deemed" status was renewed
    periodically and was in effect at the time of the events giving
    rise to the plaintiff's complaint.
    - 5 -
    As a Health Center employee, Dr. Roca was purportedly
    "permitted," at least "[i]n case[s] of emergency, . . . to do
    everything possible to save the patient's life or to save the
    patient from serious harm."              Separately, Dr. Roca's employment
    contract    with    the    Health    Center    required       him   to    "maintain
    [clinical] privileges at a hospital within a reasonable vicinity
    of [the Health Center]" — a radius that included the Hospital.
    Moreover, the contract required that he comply with "all rules,
    regulations and by-laws promulgated by [the Health Center] and
    such other hospitals at which [he] ha[d] clinical privileges."
    In an apparent effort to satisfy the first requirement,
    Dr. Roca applied for — and received — clinical privileges at the
    Hospital.     To satisfy the second requirement, Dr. Roca needed to
    comply with "all rules, regulations and by-laws" of both the Health
    Center and the Hospital. The record does not contain any compendia
    of these rules, regulations, and by-laws — but it does contain
    evidence that the Health Center required Dr. Roca to participate
    in   the   Health    Center's       "departmental      call    schedule,"       which
    included    responsibility       for     "addressing    all     [Health    Center]
    patient care responsibilities when such patients . . . present[ed]
    at [the Hospital]." In addition, there is evidence that the Health
    Center allowed Dr. Roca to set aside "[o]ne day of the week or a
    portion     thereof"      to   perform    "operative     procedures"       at    the
    Hospital.
    - 6 -
    The record is silent as to the capacity in which Dr.
    Roca came to attend to Allen's care in the Hospital.             We do know,
    however, that Allen was not a Health Center patient.
    C
    This brings us to the travel of the case.              On June 20,
    2019, the plaintiff — on behalf of Allen's estate — brought suit
    in a Massachusetts state court.          He alleged, among other things,
    that the Hospital and Dr. Roca negligently caused Allen's death.
    In   due   course,   the   Department    of   Health    and   Human
    Services (HHS) notified the Attorney General's representative, the
    United States Attorney for the District of Massachusetts, that a
    claim had been brought "against [Dr. Roca], a former employee of
    [the Health Center]."    The government subsequently appeared in the
    state court "for the limited purpose of notifying the court
    regarding whether or not the Secretary of HHS has concluded that
    [Dr. Roca] was 'deemed' to be an 'employee of the Public Health
    Service' with respect to the actions or omissions that are the
    subject of this civil action."           See 
    42 U.S.C. § 233
    (l)(1).       The
    government represented that "HHS ha[d] not yet provided its full
    report as to whether [Dr. Roca] has deemed status under 
    42 U.S.C. §§ 233
    (g) and (h) [and] whether that extends to the acts or
    omissions that are the subject of this civil action."               See 
    id.
    Nor had the Attorney General yet "been provided with sufficient
    information" to determine "whether the acts alleged fall within
    - 7 -
    the scope of 
    42 U.S.C. § 233
    (a), the applicable provisions of the
    [Federally Supported Health Centers Assistance Act], and/or were
    otherwise within the scope of the entity or individual's 'deemed'
    employment."   The government assured the court that the Attorney
    General would make such a determination "[o]nce HHS has completed
    its review and provided its report."        The record does not contain
    anything indicating whether the HHS review was ever completed or
    whether such a report was ever compiled.
    On   March   23,   2021,   the   plaintiff   filed   an   amended
    complaint, adding claims and defendants.         As relevant here, the
    amended complaint alleged eight counts against Dr. Roca for, among
    other things, wrongful death.        All eight counts implicated Dr.
    Roca's allegedly negligent treatment of Allen at the Hospital and
    sought damages for that alleged malpractice.
    Three weeks after the amended complaint was filed, the
    government removed the case to the federal district court pursuant
    to 
    42 U.S.C. § 233
    (c).       In its notice of removal, the government
    represented that Dr. Roca "was at all relevant times employed by"
    the Health Center and "acting within the scope of such employment."
    See 
    42 U.S.C. § 233
    (c).         The plaintiff did not challenge the
    propriety of the removal through a motion for remand.          See id.2
    2 Given the absence of any such challenge, we take no view as
    to whether 
    42 U.S.C. § 233
    (c) provides an independent basis for
    removal of a case filed in state court against an entity receiving
    funds under 42 U.S.C. § 254b or any employee of such an entity.
    - 8 -
    The government then moved to substitute itself as the
    named defendant in place of Dr. Roca.     The notice of substitution
    represented that "Dr. Roca was an employee of [the Health Center]
    during the time alleged in the Amended Complaint" and that "[the
    Health Center] and its employees were deemed eligible for Federal
    Tort Claims Act malpractice coverage effective January 1, 2015."
    Thus, the government concluded:
    Dr. Roca was, at the time of the acts alleged
    in th[e] Amended Complaint, acting in the
    course and scope of his employment pursuant to
    the Federally Supported Health Care Centers
    Assistance Act of 1995 (
    Pub. L. 102-501
    ) and
    
    42 U.S.C. § 233
    (a). As such, any claims for
    negligence   related   to   alleged  acts   or
    omissions of Dr. Roca fall within the [Federal
    Tort Claims Act], and the exclusive remedy for
    the plaintiff in this case is against the
    United States of America.
    In further support of substitution, the government filed
    a certification signed by the Acting United States Attorney for
    the   District   of   Massachusetts.     This   certification   neither
    mentioned nor relied upon 
    42 U.S.C. § 233
    .        Rather — citing the
    Westfall Act, 
    28 U.S.C. § 2679
     — the Acting United States Attorney
    certified that:
    Compare Celestine v. Mount Vernon Neighborhood Health Ctr., 
    403 F.3d 76
    , 81-82 (2d Cir. 2005) (holding that 
    42 U.S.C. § 233
    (c)
    provides   an   independent   basis   for   removal   under   such
    circumstances), with El Rio Santa Cruz Neighborhood Health Ctr.,
    Inc. v. U.S. Dep't of Health & Hum. Servs., 
    396 F.3d 1265
    , 1268
    (D.C. Cir. 2005) (stating that 
    42 U.S.C. § 233
    (l) details the "two
    circumstances in which [such a] case can be removed" to a federal
    district court).
    - 9 -
    On the basis of the information now available
    with respect to the incidents alleged in the
    Amended Complaint, defendant [Dr. Roca] was
    acting at the time of the incidents under
    circumstances in which Congress has provided
    by statute that the remedy provided by the
    Federal Tort Claims Act is made the exclusive
    remedy.
    The district court granted the government's motion for
    substitution, noting that, pursuant to the Westfall Act, "the
    Acting United States Attorney has certified that [Dr. Roca] was
    acting within the scope of his employment for purposes of the
    Federal Tort Claims Act at the time of the incidents giving rise
    to" the amended complaint.         The government then moved to dismiss
    the eight counts against it for lack of subject matter jurisdiction
    and failure to state a claim.          See Fed. R. Civ. P. 12(b)(1), (6).
    The   government    argued    that    the   court     lacked    subject    matter
    jurisdiction     because     the     plaintiff   had     failed     to    exhaust
    administrative remedies as required by the Federal Tort Claims Act
    (FTCA).    See     
    28 U.S.C. § 2675
    (a).      In    the     alternative,   the
    government sought dismissal on statute-of-limitations grounds.
    See 
    id.
     § 2401(b).       The plaintiff opposed the motion, arguing in
    part that the government should not have been substituted for Dr.
    Roca.
    The district court found the plaintiff's opposition
    unpersuasive and granted the government's motion.                See O'Brien v.
    Lowell Gen. Hosp., No. 21-10621, 
    2021 WL 5111857
    , at *5 (D. Mass.
    - 10 -
    Nov. 3, 2021).      The court rejected the plaintiff's contention that
    the substitution of the United States for Dr. Roca was improper.
    See 
    id. at *2-3
    .          It ruled that — contrary to the plaintiff's
    assertion — "Dr. Roca acted within the scope of his federal
    employment    at    the    time   of   the   events     giving   rise    to"   the
    plaintiff's claims.        
    Id. at *3
    .     The court reasoned, albeit on an
    incomplete record, that "[a]s a condition of his contract with his
    employer, [the Health Center], a federally funded facility, Dr.
    Roca was required to maintain privileges at the Hospital and to
    provide care in emergency situations, i.e. to provide the care at
    issue here."       
    Id.
        In support, the court stated that Dr. Roca's
    "actions were taken pursuant to his contractual obligations and
    were meant to serve his employer."              
    Id.
       The court then held that
    the substitution of the United States for Dr. Roca was warranted
    under the Westfall Act and that the plaintiff's claims therefore
    arose under the FTCA.        See 
    id.
    The     court    proceeded     to     dismiss   the   eight    counts
    originally brought against Dr. Roca on statute-of-limitations
    grounds.     See 
    id. at *4-5
    .          Because the United States had been
    substituted for Dr. Roca, the court applied the two-year statute
    of limitations applicable to claims arising under the FTCA, see
    
    id. at *4
    ; see also 
    28 U.S.C. § 2401
    (b), rather than the three-
    year statute of limitations applicable to medical malpractice
    claims arising under Massachusetts law, see Mass. Gen. Laws ch.
    - 11 -
    260, § 4.    And having found the plaintiff's claims to be time-
    barred, the court chose to bypass the government's exhaustion-of-
    remedies defense.     See O'Brien, 
    2021 WL 5111857
    , at *3-5.
    The   plaintiff   filed   a    notice    of   appeal,   which   was
    premature because the case was still pending against the Hospital
    and other defendants.      We held the appeal in abeyance while the
    plaintiff sought and received a partial final judgment.              See Fed.
    R. Civ. P. 54(b).        Based on the district court's Rule 54(b)
    certification, see O'Brien v. Lowell Gen. Hosp., 
    594 F. Supp. 3d 161
    , 162 (D. Mass. 2022), we allowed the appeal to proceed.
    II
    On appeal, this case has taken on new dimensions.               The
    plaintiff challenges both the order allowing substitution and the
    order allowing the government's motion to dismiss.              With respect
    to the first of these challenges, the plaintiff argues that the
    United States should not have been permitted to substitute itself
    for Dr. Roca under the Westfall Act because Dr. Roca was "acting
    outside of the scope of his employment at the time" of the events
    giving rise to the suit.        Instead of meeting this argument head-
    on,   the   government    now    concedes     that    the    Westfall   Act's
    substitution provisions do not apply in this case.              But although
    the government confesses error in this regard, it asserts that the
    error was harmless:      substitution was proper, it suggests, under
    the PHSA, specifically, 
    42 U.S.C. § 233
    .
    - 12 -
    Even though the government sketched the framework of
    this argument in its reply memorandum on the motion to dismiss, it
    neither developed the argument in the district court nor relied
    upon it at that time.            In view of the government's changed
    position,     we   directed     it   to    provide   additional       information
    regarding whether the requirements of 
    42 U.S.C. § 233
     had been
    satisfied.     The government responded in the affirmative, insisting
    that the services rendered by Dr. Roca fit within parameters
    previously determined by the Secretary of HHS (the Secretary) to
    come within the reach of section 233.                Thus — the government
    submitted — Dr. Roca qualified for substitution and FTCA coverage
    in this case.
    III
    "We review de novo a district court's allowance of a
    motion   to    dismiss    for   failure     to   state    a   claim   under   Rule
    12(b)(6)."     Rivera v. Kress Stores of P.R., Inc., 
    30 F.4th 98
    , 102
    (1st Cir. 2022).         So, too, we review de novo a district court's
    grant of a motion to substitute the United States in lieu of a
    named defendant.      See Kearns v. United States, 
    23 F.4th 807
    , 811
    (8th Cir. 2022); McIntyre v. United States, 
    545 F.3d 27
    , 40 (1st
    Cir. 2008).     In conducting this tamisage, we are not wedded to the
    district court's reasoning but, rather, may resolve the appeal on
    any basis that is apparent from the record.              See Alston v. Spiegel,
    
    988 F.3d 564
    , 571 (1st Cir. 2021).
    - 13 -
    A
    Although the government has abandoned its reliance on
    the Westfall Act, 
    28 U.S.C. § 2679
    (d), our analysis necessarily
    begins with an explanation of the mechanics of that statute's
    substitution provisions and why those provisions do not apply in
    this case.      The Westfall Act provides, in relevant part, that
    "[w]hen a federal employee is sued for wrongful or negligent
    conduct," the Attorney General may "certify that the employee 'was
    acting within the scope of his office or employment at the time of
    the incident out of which the claim arose.'"         Osborn v. Haley, 
    549 U.S. 225
    , 229-30 (2007) (quoting 
    28 U.S.C. § 2679
    (d)(1), (2)).
    When the Attorney General so certifies, "the employee is dismissed
    from   the   action, . . . the    United    States   is     substituted    as
    defendant in place of the employee," and "[t]he litigation is
    thereafter governed by the [FTCA]."         
    Id. at 230
    .
    Here, the Attorney General, through the Acting United
    States Attorney for the District of Massachusetts, certified —
    pursuant to the Westfall Act — that Dr. Roca was acting within the
    scope of his employment when he administered care to Allen; and
    the    district   court,   in    reliance    upon    that    Westfall     Act
    certification, allowed the substitution of the United States for
    Dr. Roca.     The district court later stated that substitution was
    appropriate because "Dr. Roca's treatment of [the] decedent was an
    - 14 -
    act within the scope of his [federal] employment."3                      O'Brien, 
    2021 WL 5111857
    , at *3.
    The tectonic plate shifted, though, when the government
    confessed    error     in     this        court.     It    acknowledged       that   —
    notwithstanding its previous filings — the Westfall Act does not
    apply at all to the issue of substitution in this case because Dr.
    Roca was not a federal employee.                   See Thomas v. Phoebe Putney
    Health Sys., Inc., 
    972 F.3d 1195
    , 1203 (11th Cir. 2020) (explaining
    that reliance on Westfall Act was "mistaken" in case brought
    against   employees    of     federally       funded      health    center   "because
    § 2679(d)    applies        only     to     'employees     of      the   government'"
    (alteration omitted)); see also Vélez-Díaz v. Vega-Irizarry, 
    421 F.3d 71
    , 75 (1st Cir. 2005) (explaining that Westfall Act allows
    for substitution of United States when "a federal employee [is]
    named as a defendant" (quoting Lyons v. Brown,

    , 606
    (1st Cir. 1998))).4         But in an effort to snatch victory from the
    3 The district court hinged its analysis of the substitution
    question on 
    28 U.S.C. § 2679
    (d)(1), which applies to cases
    originally brought in a federal court.       See O'Brien, 
    2021 WL 5111857
    , at *2-3. The court's analysis should have proceeded under
    
    28 U.S.C. § 2679
    (d)(2), which applies to cases commenced in a state
    court. Here, however, that bevue is beside the point.
    4 Our decision in Gonzalez v. United States, 
    284 F.3d 281
     (1st
    Cir. 2002), as corrected (May 8, 2002), does not throw shade on
    this confession of error. Although Gonzalez may be read to suggest
    that the Westfall Act allows the government to substitute itself
    for a named defendant when a case is brought against a PHS
    employee, see 
    id. at 286
    , the substitution decision there was not
    challenged on appeal, and we had no reason to address whether 28
    - 15 -
    jaws   of   defeat,   the   government   offered    a   new    rationale    for
    substitution:     it said that a different statute, the PHSA, 
    42 U.S.C. § 233
    , authorizes substitution where, as here, a suit is
    brought against a "deemed" employee of the PHS.               See Thomas, 972
    F.3d at 1198 (explaining that the Westfall Act and 
    42 U.S.C. § 233
    establish two "separate statutory scheme[s]" for substitution).
    The   differences   between    the     Westfall     Act   and   the
    relevant portions of the PHSA are real, not simply technical.               The
    Westfall Act applies generally to federal employees acting within
    the scope of their employment.       See Vélez-Díaz, 
    421 F.3d at 75
    .
    The PHSA, however, applies to private employees, not government
    actors; and to obtain its protection with respect to tort claims,
    an individual must not only be acting within the scope of his
    employment but also must check a series of other boxes.                     The
    government now contends that its substitution for Dr. Roca was
    U.S.C. § 2679(d)(2) provided a proper basis for substitution.
    Thus, the question remains open. See United States v. DiPina, 
    178 F.3d 68
    , 73 (1st Cir. 1999) (explaining that if, "in a prior
    decision, we have not considered an issue directly and assessed
    the arguments of parties with an interest in its resolution, that
    [prior] decision does not bind us in a subsequent case where the
    issue is adequately presented and squarely before us"); E.E.O.C.
    v. Trabucco, 
    791 F.2d 1
    , 4 (1st Cir. 1986) (noting that "an issue
    of law must have been heard and decided" to constitute binding
    precedent).
    - 16 -
    appropriate under the PHSA and urges us to affirm the substitution
    on that alternate ground.5
    B
    We pause to put the government's new contention into
    context.   The PHSA protects officers and employees of the PHS from
    personal liability "for damage for personal injury, including
    death,   resulting   from   the   performance     of   medical,   surgical,
    dental, or related functions" while acting within the scope of
    their employment.     
    42 U.S.C. § 233
    (a); see Hui v. Castaneda, 
    559 U.S. 799
    , 806 (2010) (holding that PHS officers and employees are
    "absolute[ly]   immun[e] . . . for      actions    arising   out    of   the
    performance of medical or related functions within the scope of
    their employment").     In lieu of personal liability, the statute
    makes available a tort action against the United States under the
    FTCA as the "exclusive" remedy for certain "act[s] or omission[s]"
    on the part of PHS employees resulting in personal injury or death.
    
    42 U.S.C. § 233
    (a).
    5 In his response to the government's supplemental filing,
    the plaintiff asserts that the government has waived this argument.
    We reject this assertion. Waiver doctrine is less readily applied
    to bar new arguments offered on behalf of an appellee. Cf. Alston,
    988 F.3d at 571 (noting that court of appeals "may affirm an order
    of dismissal on any ground made manifest by the record"). And in
    any event, we have discretion to overlook waiver in the interests
    of justice. See United States v. Tkhilaishvili, 
    926 F.3d 1
    , 19
    (1st Cir. 2019); Correa v. Hosp. S.F., 
    69 F.3d 1184
    , 1196 (1st
    Cir. 1995).   We think that the interests of justice counsel in
    favor of overlooking any waiver here.
    - 17 -
    When an action is commenced against a PHS employee for
    personal injury or death resulting from the performance of medical
    functions rendered in the course of his employment, Congress has
    tasked the Attorney General with defending the action.                 See 
    id.
    § 233(a)-(b), (d).        And when such an action is commenced against
    a PHS employee in a state court, the PHSA mandates removal to the
    federal district court "[u]pon a certification by the Attorney
    General   that   the   defendant     was   acting   in   the   scope   of   his
    employment at the time of the incident out of which the suit
    arose."    Id. § 233(c).      The United States is then substituted as
    the defendant, and the case proceeds against the United States
    under the FTCA. See id. § 233(a), (c).         If, however, the "district
    court determine[s] on a hearing on a motion to remand" that a
    remedy    against   the     United   States   under      section   233(a)   is
    inappropriate, "the case shall be remanded to the State Court."
    Id. § 233(c).6
    6 In this respect, the PHSA's removal and substitution
    provisions differ from those of the Westfall Act.        Under the
    Westfall Act, "the Attorney General's [scope of employment]
    certification 'is conclusive for purposes of removal.'" Alexander
    v. Mount Sinai Hosp. Med. Ctr., 
    484 F.3d 889
    , 896 (7th Cir. 2007)
    (quoting 
    28 U.S.C. § 2679
    (d)(2)). Even if the Attorney General's
    certification is erroneous, "district courts [have] no authority
    to return cases to state courts." Osborn, 
    549 U.S. at 241
    . The
    upshot is that "[f]or purposes of establishing a forum to
    adjudicate the case . . . § 2679(d)(2) renders the Attorney
    General's certification dispositive." Id. at 242. The same is
    not true under the PHSA:          
    42 U.S.C. § 233
    (c) "expressly
    contemplates" the possibility of remand and requires federal
    district courts to send cases back to state court if they determine
    - 18 -
    The   situation     is   substantially    similar    but    subtly
    different for certain federally funded health centers and their
    employees.            Under   the    Federally      Supported   Health     Centers
    Assistance Act of 1995 (FSHCAA), public or non-profit private
    health centers receiving federal funds under 42 U.S.C. § 254b — as
    well       as   officers,     board      members,    employees,     and    certain
    contractors of such entities — are eligible for the same PHSA and
    FTCA protections as are enjoyed by PHS employees.7                         See id.
    § 233(g)(1)(A).          To gain this prophylaxis, a federally funded
    health center or any particular individual associated with it must
    be "deemed to be an employee" of the PHS.              Id.   Health centers and
    affiliated individuals (such as employees) that are so "deemed"
    are — subject to certain conditions — eligible for FTCA protection
    "to the same extent" as PHS employees.               Id. § 233(g)(1)(A)-(B).
    This means, among other things, that if an action is
    brought in state court against a "deemed" PHS employee, the FSHCAA
    provides mechanisms both for removing the case to the federal
    district court and for substituting the United States as the named
    defendant in the "deemed" employee's stead.                  One such mechanism
    that a "remedy by suit against the United States is not available."
    Thomas, 972 F.3d at 1203.
    Federally funded health centers are health centers that
    7
    receive grants under 42 U.S.C. § 254b. Such health centers are
    located in medically underserved areas and/or serve medically
    underserved populations. See Consejo de Salud de la Comunidad de
    la Playa de Ponce, Inc. v. González-Feliciano, 
    695 F.3d 83
    , 86 n.1
    (1st Cir. 2012).
    - 19 -
    directs that, within fifteen days of being notified of such a case,
    the Attorney General may appear in state court and "advise such
    court   as   to   whether   the   Secretary   has   determined"   that   the
    defendant "is deemed to be an employee of the [PHS] . . . with
    respect to the actions or omissions that are the subject of [the]
    civil action or proceeding."         
    Id.
     § 233(l)(1).      If the Attorney
    General advises the court that the defendant has been "deemed" a
    PHS employee "with respect to the actions or omissions" giving
    rise to the plaintiff's claims, removal is in order.          Id.; see id.
    § 233(c).     And once a case has been removed to the federal court,
    the United States may move for substitution so that the case will
    proceed under the FTCA.       See id. § 233(a), (c); see also Thomas,
    972 F.3d at 1198.
    The authority to deem an entity or affiliated individual
    an employee of the PHS — both generally and for purposes of a
    specific lawsuit — rests with the Secretary.                See 
    42 U.S.C. § 233
    (g)(1).      To obtain deemed status, a health center must submit
    an application to the Secretary attesting that it and/or particular
    officers, board members, employees, or contractors satisfy certain
    statutory     criteria.     See    
    id.
       § 233(g)(1)(D);    see   also   id.
    §§ 233(g)(1)(B)-(C), (h).         The Secretary must make a "deeming"
    determination within thirty days of receipt of the application.
    See id. § 233(g)(1)(E).      Once the Secretary has determined that an
    entity or individual is deemed to be an employee of the PHS, that
    - 20 -
    determination goes into effect for "a calendar year that begins
    during   a   fiscal       year."     Id.    § 233(g)(1)(A);      § 233(k).       The
    Secretary's "deeming" determination is then renewable on an annual
    basis,   provided     that     the   entity       submits   yearly    applications
    verifying that it and/or its officers, board members, employees,
    or contractors continue to meet the requisite statutory criteria.
    See id. § 233(g)(1)(D); see also Agyin v. Razmzan, 
    986 F.3d 168
    ,
    172 (2d Cir. 2021); Thomas, 972 F.3d at 1197 n.1.
    We hasten to add that the Secretary's annual "deeming"
    determination      does     not    conclusively      establish    PHSA   and    FTCA
    coverage with respect to a particular lawsuit when — as in this
    case — an action is brought against a physician affiliated with a
    federally funded health center.                 Rather, coverage hinges on the
    circumstances in which care has been provided.                       See 
    42 U.S.C. § 233
    (g)(1)(B)-(C). With respect to patients of the health center,
    coverage     is     straightforward:              the   Secretary's      "deeming"
    determination "appl[ies] with respect to services provided" to
    "all patients of the entity."              
    Id.
     § 233(g)(1)(B)(i).
    The question of coverage is more nuanced where, as here,
    care is provided to an individual who is not a health center
    patient.     In that circumstance, the "deeming of" an entity or
    individual as an employee of the PHS only applies "if the Secretary
    determines,       after    reviewing       an    application     submitted     under
    subparagraph (D), that the provision of the services to such
    - 21 -
    individual[]"   meets   at   least   one   of   three   conditions.    Id.
    § 233(g)(1)(B)-(C).     Specifically, the provision of such services
    must either:
    (i) benefit[] patients of the entity and
    general populations that could be served by
    the     entity     through    community-wide
    intervention efforts within the communities
    served by such entity;
    (ii) facilitate[] the provision of services to
    patients of the entity; or
    (iii) [be] otherwise required under an
    employment contract (or similar arrangement)
    between the entity and [the particular]
    officer, governing board member, employee, or
    contractor of the entity.
    Id. § 233(g)(1)(C); see 
    42 C.F.R. § 6.6
    (d).             Under subparagraph
    (D), "[t]he Secretary may not . . . deem an entity or an officer,
    governing board member, employee, or contractor of the entity to
    be an employee of the [PHS] . . . , and may not apply such deeming
    to services" provided to persons who are not patients of the
    entity, "unless the entity has submitted an application for such
    deeming to the Secretary."      
    42 U.S.C. § 233
    (g)(1)(D).         Congress
    has afforded the Secretary the power to prescribe the "form" and
    "manner" of such applications.       
    Id.
    HHS regulations reaffirm that FTCA coverage extends to
    "services provided to individuals who are not patients of a covered
    entity . . . only if the Secretary determines that" at least one
    of the three conditions listed at 
    42 U.S.C. § 233
    (g)(1)(C) has
    - 22 -
    been satisfied.       
    42 C.F.R. § 6.6
    (d).          The Secretary has crafted
    two methods for making that determination.                  See 
    id.
     § 6.6(e)(4).
    The first method allows a health center or affiliated individual
    to   submit    an     "application . . . seek[ing]            a    particularized
    determination" that coverage extends to the care at issue.                     Id.
    The second method involves a predetermination by the Secretary
    that FTCA coverage extends in certain circumstances without any
    need for a "specific application" on the part of the entity or
    affiliated individual.         Id.    To qualify for this predetermined
    coverage, the care rendered or the "activity or arrangement in
    question" must "fit[] squarely" into one of a number of scenarios
    described in the regulation.           Id.; see id. § 6.6(e)(4)(i)-(iv)
    (describing scenarios).         If there is no square fit, the party
    seeking    coverage     must   attempt     to      obtain     "a   particularized
    determination" through the first method.              Id. § 6.6(e)(4).
    C
    With this backdrop in place, we return to the case at
    hand.     As we have said, the government has reinvented its theory
    of substitution:        it has forgone its earlier reliance on the
    Westfall Act and now relies instead on the PHSA.                    Although the
    government concedes that neither the Health Center nor Dr. Roca
    sought a particularized determination that the care he provided to
    Allen     triggered    FTCA    coverage,      it    nonetheless     claims    that
    substitution    is    appropriate    under      the   PHSA    because   the   care
    - 23 -
    rendered by Dr. Roca to Allen fits squarely within one or more of
    the scenarios described in 
    42 C.F.R. § 6.6
    (e)(4)(i)-(iv).                          In
    particular, the government urges us to find that the care provided
    by Dr. Roca fits squarely             within the scenarios described               in
    subsections (ii) and (iv).
    The plaintiff sees things differently.                     He notes that
    the   Secretary      has    never     made      a     particularized      "deeming"
    determination regarding Dr. Roca; that the existing record does
    not support the government's claim that the regulation applies;
    and that, in all events, Dr. Roca should not be regarded as acting
    within the scope of federal employment.               He also questions whether
    the Secretary has the authority to predetermine that the scenarios
    listed in 
    42 C.F.R. § 6.6
    (e) automatically qualify a "deemed" PHS
    employee for coverage under the FTCA.                 In the plaintiff's words,
    that type of "blanket deem[ing]" contravenes the text of 
    42 U.S.C. § 233
    (g)(1)(D), which prohibits the Secretary from "apply[ing]" a
    deeming decision to cover services provided to non-patients of a
    health   center     "unless    the    [health       center]     has    submitted   an
    application    for   such     deeming      to   the    Secretary."        
    42 U.S.C. § 233
    (g)(1)(D).      The statute, on the plaintiff's reading, does not
    give the Secretary the authority to "waive" the requirement that
    applications   be    submitted       and   considered      on    a    "case-by-case"
    basis.   For all of these reasons, he claims that the substitution
    of the United States for Dr. Roca was improvident.
    - 24 -
    IV
    The answer to the question of whether Dr. Roca's care
    fits squarely within one or more of the described scenarios is
    inscrutable on the existing record.8       The government principally
    relies on the scenario found at 
    42 C.F.R. § 6.6
    (e)(4)(ii).          Under
    this scenario, a "deemed" PHS employee qualifies for FTCA coverage
    when providing periodic on-call or emergency room coverage at a
    hospital   to   non-health   center    patients   if   that   "[p]eriodic
    hospital call or hospital emergency room coverage is required by
    the hospital as a condition for obtaining hospital admitting
    privileges."     
    42 C.F.R. § 6.6
    (e)(4)(ii).        To fit within this
    scenario, "[t]here must also be documentation for the particular
    health care provider [showing] that th[e] coverage is a condition
    of employment at the health center."       
    Id.
    As a fallback, the government cites to the scenario
    limned in 
    42 C.F.R. § 6.6
    (e)(4)(iv).         This scenario applies to
    "[c]overage [provided] in [c]ertain [i]ndividual [e]mergenc[y]"
    situations.     To fit within this scenario, a number of criteria
    must be satisfied.     First, a "health center provider" must be
    "providing or undertaking to provide covered services to [either]
    a health center patient within the approved scope of project of
    8 For purposes of this discussion, we do not address the
    plaintiff's overarching challenge to the legality of certain of
    the Secretary's regulations.
    - 25 -
    the [health] center, or to an individual who is not a patient of
    the health center under the conditions set forth in [
    42 C.F.R. § 6.6
    ]."         
    Id.
        § 6.6(e)(4)(iv).         Second,     while    providing    or
    undertaking to provide such services, "the provider [must be]
    asked, called upon, or undertake[] . . . to temporarily treat or
    assist in treating [a] non-health center patient" experiencing an
    emergency.       Id.    Third, the provision of care must be "at or near
    th[e] location" where the provider was originally providing care.
    Id. And, finally, "the health center must have documentation (such
    as employee manual provisions, health center bylaws, or an employee
    contract) [showing] that the provision of individual emergency
    treatment,       when    the      practitioner     is   already       providing    or
    undertaking       to    provide    covered   services,       is   a   condition    of
    employment at the health center."            Id.
    On the government's new theory of the case, its right to
    substitution depends on whether the care administered by Dr. Roca
    to Allen fits squarely within one or both of these scenarios.                     The
    rub, however, is that neither of these scenarios was before the
    district court.         Indeed, the regulation that creates the scenarios
    was never mentioned in that court.               It is not surprising, then,
    that the record is bereft of much of the documentation needed to
    assess the applicability vel non of these scenarios.                      In short,
    the record — as presently constituted — simply does not allow us
    to   make    a    reasoned     determination       as   to    whether     the     care
    - 26 -
    administered to Allen by Dr. Roca fits squarely within either of
    the scenarios that the government labors to invoke.
    The government admits as much but tells us that we may
    fill the gaps by resorting to imagined knowledge of "standard
    practices" and by accepting new evidentiary proffers.                    On this
    gap-filled    record,    though,    we    lack    a   sufficient       basis   for
    determining    what   practices     are    "standard"       in   the   community
    hospital setting.       In addition, we repeatedly have cautioned that
    appeals cannot be decided on the basis of evidentiary materials —
    other than those that are susceptible to judicial notice — not
    incorporated in the district court record.                  See, e.g., United
    States v. Kobrosky, 
    711 F.2d 449
    , 457 (1st Cir. 1983) ("We are an
    appellate tribunal, not a nisi prius court; evidentiary matters
    not first presented to the district court are, as the greenest of
    counsel   should    know,   not    properly      before   us."    (emphasis    in
    original)).
    To say more would be to paint the lily.             The government
    has   confessed    error,   acknowledging     that    the    district     court's
    favorable decision on a critical issue — whether the United States
    should be substituted for Dr. Roca — rests on a porous foundation.
    To shore up that porous foundation, the government asks us to put
    our stamp of approval on an alternative theory for substitution.
    But the government has not pointed to evidence in the record
    sufficient to support its new theory and — equally as important —
    - 27 -
    the plaintiff has had no opportunity to offer evidence relating to
    that theory, to challenge the government's suggested evidence, or
    to present his legal arguments.        To cinch the matter, the district
    court has had no opportunity to consider the government's revamped
    position and to give us the benefit of its thinking.                  See CSX
    Transp.,   Inc.   v.   Healey,   
    861 F.3d 276
    ,    287   (1st   Cir.   2017)
    (explaining that "[w]e often hesitate to address in the first
    instance issues on which we lack the benefit of a district court's
    consideration"); see also Rivera-Corraliza v. Morales, 
    794 F.3d 208
    , 217 (1st Cir. 2015) (remanding when court of appeals did not
    have benefit of district court's evaluation of arguments).
    This is a court of appeals, and that nomenclature aptly
    describes our core function.      Appellate courts are, by definition,
    courts of review.      They are not courts of first instance.             In the
    awkward posture in which this case now stands, we think it both
    fair and prudent to vacate the substitution order, vacate the
    partial final judgment entered below, and remand for further
    proceedings consistent with this opinion.            On remand, the district
    court should allow such limited discovery as may be necessary for
    the resolution of the substitution issue.            See N. Am. Cath. Educ.
    Programming Found., Inc. v. Cardinale, 
    567 F.3d 8
    , 18 (1st Cir.
    2009).

    V
    We need go no further.            The question of whether the
    United States should be substituted for Dr. Roca is a threshold
    question.    Until that question is resolved, there is no way to
    know whether the FTCA applies to this suit.               Consequently, there
    would be no point in addressing either the issue of whether the
    FTCA's exhaustion-of-remedies requirement, 
    28 U.S.C. § 2675
    (a),
    forecloses the exercise of subject matter jurisdiction or the issue
    of whether the plaintiff's action is time-barred.              For the reasons
    elucidated above, both the substitution order and the partial final
    judgment    are   vacated   and   the       case   is   remanded   for   further
    proceedings consistent with this opinion.               The parties shall bear
    their own costs.
    Vacated and remanded.
