    Before EBEL, McKAY and BRISCOE, Circuit Judges.
    EBEL, Circuit Judge.
    On the evening of Saturday, April 25, 1998, twenty-five year-old Hardy
    Haceesa walked into a hospital emergency room complaining of a fever, difficult
    and painful breathing, chest discomfort, and general achiness. He told the nurse
    he thought his condition could be the result of exposure to mice. Haceesa was
    sent home that night, diagnosed with bronchitis and told to check back at the local
    clinic on Monday. By Tuesday evening, he was dead.
    Only after his death was Haceesa’s disease diagnosed correctly: he died of
    hantavirus pulmonary syndrome, a rare, deadly disease caused by exposure to
    airborne particles of the urine of infected mice and characterized in its early
    stages by flu-like symptoms. Haceesa was a Navajo Indian, and the hospital
    where he was first seen on April 25 – the Northern New Mexico Navajo Hospital
    in Shiprock, New Mexico – is owned and operated by the Indian Health Service,
    an agency of the United States Department of Health and Human Services. As the
    district court observed, Shiprock Hospital stands “in the geographic center of the
    world for” hantavirus.
    The present suit was brought by Haceesa’s widow Beverly Haceesa and his
    four year-old daughter Shenoel, alleging medical malpractice in the failure to
    diagnose Haceesa’s hantavirus. The suit was brought against the United States
    under the Federal Tort Claims Act (FTCA), 
    28 U.S.C. §§ 1346
    (b), 2671 et seq.
    After a bench trial in federal district court for the District of New Mexico, the
    -2-
    court found the Government liable and awarded the Plaintiffs damages of over
    $2.1 million. 1 On appeal, the Government no longer disputes its liability, but
    challenges the damages awarded on three distinct grounds. First, it argues that
    New Mexico’s $600,000 statutory cap on medical malpractice recoveries applies
    to the Plaintiffs’ suit. Second, the Government argues that its liability should be
    reduced to reflect its comparative negligence relative to a subsequent health care
    provider that also failed to diagnose Haceesa’s hantavirus. Third, it argues that
    certain of the Plaintiffs’ claims are barred because they were not administratively
    exhausted at the time suit was filed. The district court rejected all three
    arguments. We conclude that the district court erred (1) in concluding that the
    recovery cap did not apply; (2) in failing to calculate the Government’s liability
    on the basis of New Mexico’s “loss of chance” approach; and (3) in concluding
    1
    The district court found that the Plaintiffs’ total damages were
    approximately $3.3 million. Finding as fact that the Government’s negligence
    resulted in the loss of a 65 percent chance that Haceesa would survive, the court
    awarded damages in the amount of 65 percent of approximately $3.3 million or
    approximately $2.15 million (citing Alberts v. Schultz, 
    975 P.2d 1279
     (N.M.
    1999)).
    On appeal, the Plaintiffs do not challenge the district court’s decision to
    reduce the judgment to 65 percent of their damages. Additionally, the
    Government did not argue below, and specifically disclaimed at oral argument an
    intention of arguing here, that the damages awarded should have been offset by
    the amount of a settlement between the Plaintiffs and another hospital that also
    failed properly to diagnose Haceesa’s condition.
    -3-
    that the Estate’s claim for wrongful death was timely filed. Accordingly, we
    reverse and remand for further proceedings consistent with this opinion.
    I. APPLICATION OF THE FTCA TO NEW MEXICO’S
    CAP ON MEDICAL MALPRACTICE RECOVERIES
    The district court awarded the Plaintiffs over $2.1 million in damages. The
    Government argues on appeal that this damages award should have been subject
    to New Mexico’s $600,000 cap on medical malpractice recoveries. N.M. Stat.
    § 41-5-6(A) (“the recovery cap”). The district court rejected this argument:
    The New Mexico cap on damages under the New
    Mexico Medical Malpractice Act does not apply in this case.
    The cap only applies to negligence by a “health care provider,”
    which is defined as a “person, corporation, organization,
    facility or institution licensed or certified by this state to
    provide health care or professional services as a doctor of
    medicine, hospital, outpatient health care facility, doctor of
    osteopathy, chiropractor, podiatrist, nurse anesthetist or
    physician’s assistant.” NMSA § 41-5-3(A). Plaintiffs’ claims
    against the hospital administrators who elected to provide
    absolutely no training to Nurse Rhodes, as well as their claims
    of negligence against Nurse Rhodes, are not capped under the
    statute.
    In other words, the district court concluded that (1) the recovery cap applies only
    to suits against health care providers, and (2) that Haceesa’s suit against hospital
    administrators and a nurse was not a suit against health care providers. On
    appeal, the Government challenges each of these conclusions. The Plaintiffs,
    meanwhile, argue for affirmance on the alternative ground that, under New
    -4-
    Mexico law, the Government is not entitled to the benefit of the recovery cap.
    After summarizing the relevant law, we address each of these three arguments
    below. 2
    Under the FTCA, the United States is liable for its tortious conduct in the
    same manner and to the same extent as a private individual under like
    circumstances in that jurisdiction would be liable. 
    28 U.S.C. §§ 1346
    (b), 2674.
    Here, our charge is to determine first the scope and applicability of the limits
    New Mexico statutes impose on the medical malpractice liability of private
    entities.
    New Mexico’s recovery cap provides: “Except for punitive damages and
    medical care and related benefits, the aggregate dollar amount recoverable by all
    persons for or arising from any injury or death to a patient as a result of
    malpractice shall not exceed six hundred thousand dollars ($600,000) per
    occurrence.” N.M. Stat. § 41-5-6(A). “A health care provider’s personal liability
    is limited to two hundred thousand dollars ($200,000) for monetary damages and
    2
    The Government did not argue below, and conceded at oral argument that
    it does not argue here, that Government liability for the actions of the hospital
    administrators in failing to train hospital employees or implement appropriate
    patient assessment protocols is barred by 
    28 U.S.C. § 2680
    (a) (stating that FTCA
    waiver of immunity “shall not apply to – (a) Any claim . . . based upon the
    exercise or performance or the failure to exercise or perform a discretionary
    function or duty on the part of a federal agency or an employee of the
    Government, whether or not the discretion involved be abused.”).
    -5-
    medical care and related benefits . . . . Any amount due from a judgment or
    settlement in excess of two hundred thousand dollars . . . shall be paid from the
    patient’s compensation fund . . . .” 
    Id.
     § 41-5-1(D). As the district court noted,
    the statute defines “health care provider” as a “person, corporation, organization,
    facility or institution licensed or certified by this state to provide health care or
    professional services as a doctor of medicine, hospital, outpatient health care
    facility, doctor of osteopathy, chiropractor, podiatrist, nurse anesthetist or
    physician’s assistant.” N.M. Stat. § 41-5-3(A). “‘[M]alpractice claim’ includes
    any cause of action arising in this state against a health care provider for medical
    treatment, lack of medical treatment or other claimed departure from accepted
    standards of health care . . . .” Id. § 41-5-3(C).
    Not all “health care providers,” however, are entitled to the benefit of the
    recovery cap: “A health care provider not qualifying under this section shall not
    have the benefit of any of the provisions of the Medical Malpractice Act in the
    event of a malpractice claim against it.” Id. § 41-5-5(C). In order to be
    “qualified,” a health care provider must “(1) establish its financial responsibility
    by filing proof . . . of malpractice liability insurance . . . of at least two hundred
    thousand dollars . . .; and (2) pay the [Patient’s Compensation Fund] surcharge.”
    Id. § 41-5-5(A).
    -6-
    A. Whether the recovery cap applies to a suit against the Government
    The Plaintiffs argue that we need not reach the question of whether the
    district court’s rationale for refusing to apply the recovery cap is correct, because
    the Government is not “qualified” within the meaning of the Medical Malpractice
    Act and therefore ineligible to benefit from the recovery cap. The Government
    does not dispute that it has not filed proof of liability insurance and has not paid
    any surcharge into the Patients’ Compensation Fund, and thus, by the terms of
    section 41-5-5, is not “qualified.”
    Three circuits have considered arguments similar to that now offered by the
    Plaintiffs, and all three circuits have held that the Government was entitled to the
    recovery cap despite failure to file proof of financial responsibility and to
    contribute to a compensation fund. See Carter v. United States, 
    982 F.2d 1141
    ,
    1143-44 (7th Cir. 1992); Lozada v. United States, 
    974 F.2d 986
    , 987 (8th Cir.
    1992); Owen v. United States, 
    935 F.2d 734
    , 737-38 (5th Cir. 1991). The
    rationale supporting these holdings is that (1) the FTCA refers to like
    circumstances rather than identical circumstances, 3 (2) the financial responsibility
    3
    This reasoning is consistent with Tenth Circuit case law. See Nationwide
    Mut. Ins. Co. v. United States, 
    3 F.3d 1392
    , 1396 (10th Cir. 1993) (“Recognizing
    that the United States is seldom situated identically to private parties, however,
    the ‘like circumstances’ inquiry requires only that the United States be analogized
    to a similarly situated private party. Nice pieces of casuistry and hypersensitive
    legalisms are to be avoided in interpreting this language.” (internal quotation
    (continued...)
    -7-
    of the United States is assured, and (3) its failure to contribute to a compensation
    fund is immaterial because (unlike qualified providers) it must pay its liabilities
    without resort to the compensation fund. 4 This court has endorsed these holdings.
    Hill v. United States, 
    81 F.3d 118
    , 121 (10th Cir. 1996) (citing, inter alia, Carter,
    Lozada, and Owen, and stating, “These cases stand for the proposition that where
    there is a specific cap on tort liability, the United States government may benefit
    from this limit although it did not otherwise participate in the statutory scheme
    which provides the cap. . . .” 5
    (...continued)
    3
    marks and alterations omitted, citations to Carter and others omitted)).
    4
    Here we hold that the Government’s liability is subject only to the
    $600,000 cap and not to the individual $200,000 cap because the lower individual
    cap assumes that the amount of damages in excess of $200,000 would be paid by
    the compensation fund. The Government did not pay into the compensation fund
    and hence cannot look to it to help pay the damage award.
    5
    Haceesa urges that Hill supports rather than undercuts his position by
    highlighting its statement that “None of these cases [Carter, etc.] offers direct
    support for the proposition that the United States may attempt to create a rough
    equivalent to a state statute when they clearly are ineligible for the precise remedy
    provided therein.” 
    81 F.3d at 121
    . Hill drew a distinction between state statutes
    such as those in Carter, Lozada, and Owen “where there is a specific cap on tort
    liability” with the situation where the United States was ineligible for a particular
    remedy yet urged a court “to fashion a remedy that will further the intent and
    approximate the outcome of a statute.” 
    Id. at 120-21
    . The quoted language relied
    upon by Haceesa does not support her position, because the statutory remedy at
    issue here is substantially identical to the “specific cap on tort liability” that Hill
    regarded the United States as “undoubtedly” eligible for. 
    Id.
    -8-
    The Plaintiffs endeavor to distinguish Carter, Lozada, and Owen by arguing
    that New Mexico law “require[s] the United States to attend a Medical Review
    Panel hearing” and “grants plaintiffs the benefit of having a physician selected to
    assist them in continuing to pursue their claims if they are found to have merit.”
    In essence, Haceesa’s theory (offered without supporting authority) is that
    participation in the medical review commission procedures amounts to a
    qualification for purposes of section 41-5-5, and that New Mexico’s qualification
    procedure thus is materially different from those at issue in Carter, Lozada, and
    Owen. We disagree. The Medical Malpractice Act establishes two actions that a
    health care provider “shall” perform “[t]o be qualified”: filing proof of insurance
    and payment of a compensation fund surcharge. N.M. Stat. § 41-5-5. The
    absence from section 41-5-5 of any requirement of participation in the
    commission procedures demonstrates the error in the Plaintiffs’ argument. In any
    event, we note the Plaintiffs are mistaken that health care providers are obligated
    to attend panel hearings. Id. § 41-5-19(A) (providers and their attorneys “may”
    attend).
    The Plaintiffs next argue that “private individual[s] under like
    circumstances,” 
    28 U.S.C. § 2674
    , generally have not availed themselves of New
    Mexico’s qualification procedures, and thus the Government should not be
    regarded as having done so. (Aple B. 18 (“A review of reported New Mexico
    -9-
    cases indicates that most cases brought against negligent hospitals are outside the
    NMMMA.” (citations omitted)).) By contrast, in Carter, the Seventh Circuit
    noted that “[a]ccording to the record, more than 90% of the private medical
    providers” had satisfied analogous qualification procedures. 
    982 F.2d at 1143
    . It
    is not apparent to us why the United States should be precluded from taking
    advantage of a state liability cap just because a substantial majority of private
    medical providers voluntarily chose not to qualify as a qualified health care
    provider. In any event, the record before us is totally inadequate even to establish
    Plaintiff’s factual premise. Accordingly, this argument fails.
    Finding persuasive the holdings of all of the other circuits to address this
    issue, we conclude that the Government is not ineligible to invoke the recovery
    cap merely because it did not satisfy the relevant state qualification procedures.
    Therefore, we reject Haceesa’s proposed alternative grounds for affirmance, and
    we turn to the grounds actually relied upon by the district court for concluding
    that the recovery cap did not apply.
    B. Whether the $600,000 recovery cap applies only to health care providers.
    As noted above, the definition of health care provider does not include
    nurses (except for nurse anesthetists, which the nurse here undisputedly was not)
    or hospital administrators. On this basis, the district court concluded that the
    - 10 -
    recovery cap did not apply in the present case. The Government argues, however,
    that the $600,000 cap is not limited to actions against “health care providers,” but
    instead applies to all malpractice defendants. By its terms, the Government
    argues, section 41-5-6(A) limits how much “all persons” may recover “for or
    arising from any injury or death to a patient as a result of malpractice.” Only
    section 41-5-6(D)’s $200,000 cap on personal liability refers expressly to “health
    care providers.” The New Mexico courts have not ruled on whether the recovery
    cap applies to all malpractice actions or only those brought against health care
    providers, so we must predict how they would resolve the issue.
    The Government’s argument assumes that the phrase “amount . . . for or
    arising from any injury or death to a patient as a result of malpractice, ” § 41-5-
    6(A), has a meaning distinct from “malpractice claim,” which is defined in
    relevant part by the Act to “include[] any cause of action . . . against a health care
    provider for . . . lack of medical treatment.” N.M. Stat. § 41-5-3(C) (emphasis
    added). We need not decide this question because of our conclusion in the next
    section that the United States is a qualified health care provider for purposes of
    this suit.
    - 11 -
    C. Whether the Government is a health care provider for purposes of this
    suit.
    Ultimately, whether the recovery cap applies to the Plaintiffs’ present suit
    turns on whether this FTCA suit against the United States, arising from the
    actions of a nurse and health care administrators, is a suit against a “health care
    provider” within the meaning of the recovery cap statute. To answer this
    question, we begin with the text of the statutory provisions governing FTCA
    liability. Under 
    28 U.S.C. § 1346
    (b), “the district courts . . . shall have exclusive
    jurisdiction of civil actions on claims against the United States . . . for injury . . .
    caused by the negligent or wrongful act or omission of any employee of the
    Government while acting within the scope of his office or employment, under
    circumstances where the United States, if a private person, would be liable.”
    Under 
    28 U.S.C. § 2674
    , “the United States shall be liable . . . in the same
    manner and to the same extent as a private individual under like circumstances.”
    Finally, as already noted, New Mexico’s statutory recovery cap applies only to
    suits against “health care providers,” a term that includes hospitals but does not
    include either nurses or hospital administrators.
    The issue before us is one of statutory interpretation. If “private person,”
    § 1346(b), and “private individual,” § 2674, includes employers, then the recovery
    cap applies here because the private employer analogous to a government hospital
    is a private hospital. Section 1346(b) unmistakably is couched in the language of
    - 12 -
    an employer’s respondeat superior liability, creating jurisdiction over actions
    “against the United States . . . for injury . . . caused by the . . . wrongful act . . . of
    any employee . . . while acting within the scope of his office or employment.”
    § 1346(b). See, e.g., Restatement (Second), Agency § 219(1) (“A master is
    subject to liability for the torts of his servants committed while acting in the
    scope of their employment. ”) Further, § 1346(b) refers to “circumstances where
    the United States, if a private person, would be liable.” Because in reality the
    United States is not an individual employee but only an employer, this phrasing
    suggests that the only shoes that the Government stands in under the FTCA are
    those of private employers.
    We think the text of the FTCA best supports the Government’s employer
    interpretation, a conclusion buttressed by our rule that any waiver of sovereign
    immunity “‘must be construed strictly in favor of the sovereign and not enlarged
    beyond what its language requires.’” United Tribe of Shawnee Indians v. United
    States, 
    253 F.3d 543
    , 547 (10th Cir. 2001) (quoting United States v. Nordic
    Village, Inc., 
    503 U.S. 30
    , 34 (1991)) (internal quotation marks and alteration
    omitted).
    To the extent that this issue is not resolved by the text of the statute, we
    look to legislative intent, and we conclude that Congress has spoken to this
    question. In enacting the Federal Employees Liability Reform and Tort
    - 13 -
    Compensation Act of 1988, Congress found that “ [t]he United States, through the
    Federal Tort Claims Act, is responsible to injured persons for the common law
    torts of its employees in the same manner in which the common law historically
    has recognized the responsibility of an employer for torts committed by its
    employees within the scope of their employment.” § 2(b), 
    102 Stat. 4564
    , 
    28 U.S.C. § 2671
     note. Cf. H.R. Rep. 100-700 at 5 (1988), reprinted in 1988
    U.S.C.C.A.N. 5945, 5949 (describing government’s FTCA liability as
    “vicarious”).
    Accordingly, we conclude that the Government’s liability under the FTCA
    is limited to that of a private employer under like circumstances. Our conclusion
    is consistent with that of at least two other circuits. See St. John v. United States,
    
    240 F.3d 671
    , 676 (8th Cir. 2001) (“The FTCA is a limited waiver of sovereign
    immunity, allowing the federal government to be sued for the actions of ‘any
    employee of the Government while acting within the scope of his office or
    employment’ under circumstances where the United States would be liable if it
    were a private employer. 
    28 U.S.C. § 1346
    (b) and 2674.”); Johnson v. Sawyer,
    
    47 F.3d 716
    , 730 (5th Cir. 1995) (“All FTCA liability is respondeat superior
    liability. . . . Under the FTCA, the United States is not liable if the private
    employer would not be liable pursuant to local law.”); see also Bryant v. United
    States, 
    126 F. Supp. 2d 1227
    , 1234 (2000); cf. Gutierrez de Martinez v.
    - 14 -
    Lamagno, 
    515 U.S. 417
    , 420 (1995) (“Generally, [FTCA] cases unfold much as
    cases do against other employers who concede respondeat superior liability.”).
    The only circuit to reach a contrary conclusion did so in a split decision.
    Knowles v. United States, 
    91 F.3d 1147
    , 1150 (8th Cir. 1996) (2-1 decision).
    The issue in Knowles was similar to the one that we face, namely whether an
    FTCA suit against the United States arising from the alleged malpractice of
    medical specialists employed by the government was subject to South Dakota’s
    $1 million cap on medical malpractice damages. The Knowles majority
    concluded that the recovery cap did not apply, reasoning as follows:
    Under the FTCA, the United States will be held liable to the
    same extent as a private party. It is standing in the shoes of
    the medical service specialists. Therefore, the United States
    shares in the protection of the statute to the same extent the
    individuals would if they were sued directly. It follows, then,
    that if medical services specialists, individually, are not
    protected by the statute, neither is the United States shielded
    from the consequences of their negligence.
    
    91 F.3d at 1150
     (internal quotation marks and alterations omitted). In dissent,
    Judge Beam reasoned that “the ‘hypothetical private party’ is analogous to a
    private employer,” 
    Id. at 1153
    , and “[t]he government cannot stand in the shoes of
    a negligent federal employee, individually, because the employee is immune from
    suit.” 
    Id. at 1154
    . Ultimately, the dissent concluded that the government has
    waived immunity and hence “is liable only under a statutorily-imposed respondeat
    superior theory.” 
    Id.
    - 15 -
    We find the Knowles dissent more persuasive. The panel majority made no
    effort to come to grips with the language of § 1346(b), which, as noted above,
    supports the view that FTCA constitutes respondeat superior liability. Nor did it
    acknowledge Congress’s statement of intent in the note to § 2671. Finally, the
    majority did not purport to construe strictly Congress’s FTCA waiver of sovereign
    immunity.
    D. Conclusion
    For the foregoing reasons, we conclude that the district court’s ruling that
    New Mexico’s $600,000 recovery cap is inapplicable to the present suit is
    erroneous. We hold that, because an analogous suit against a private hospital
    based on the actions of employees who are not themselves health care providers
    would be subject to the recovery cap, the Plaintiff’s present FTCA suit against the
    Government is also subject to the $600,000 cap.
    II. CONCURRENT/SUCCESSIVE TORTFEASORS
    During trial, the Government attempted to prove that physicians at San Juan
    Regional Medical Center (San Juan Regional), where Haceesa visited and was
    treated on April 27 and 28 (after his visit to Shiprock Hospital on April 25), were
    negligent in failing to accurately diagnose Haceesa’s illness. The Government
    further argued that damages should be apportioned between it and San Juan
    - 16 -
    Regional. In its post-trial decision, the district court made no factual findings
    regarding Haceesa’s treatment at San Juan Regional, nor did it reach any
    conclusions regarding San Juan Regional’s alleged negligence. Instead, it
    concluded that “[u]nder New Mexico law, . . . the negligence of the [Government]
    [wa]s successive, and not concurrent with, any negligence of San Juan Regional
    Medical Center on April 27th and 28th, 1998,” and that, accordingly, the
    Government was liable for all damages incurred by plaintiffs. Aplt. App. at 125.
    On appeal, the Government contends that the district court erred in labeling
    it and San Juan Regional as successive rather than concurrent tortfeasors. The
    Government further argues that the district court should have quantified the fault
    of the Government relative to that of San Juan Regional and reduced the damages
    to be paid by the Government. For the reasons outlined below, we agree with the
    district court that the Government and San Juan Regional were successive
    tortfeasors, but we reject the district court’s conclusion that the Government is
    responsible for all damages incurred by the plaintiffs.
    Joint tortfeasor liability in New Mexico is governed by section 41-3A-1 of
    the New Mexico Statutes, entitled “Several liability.” This provision in effect
    defines two distinct categories of cases. One category involves cases “[w]here a
    plaintiff sustains damage as the result of fault of more than one person which can
    be causally apportioned on the basis that distinct harms were caused to the
    - 17 -
    plaintiff.” 
    N.M. Stat. Ann. § 41
    -3A-1(D). As to cases in this category, each
    tortfeasor “is severally liable only for the distinct harm which that person
    proximately caused.” 
    Id.
     The other category involves “any cause of action to
    which the doctrine of comparative fault applies,” 
    id.
     § 41-3A-1(A), which
    category implicitly consists of all joint tortfeasor cases not covered by § 41-3A-
    1(D). As to cases in this category, each tortfeasor who establishes that the fault
    of another is a proximate cause of a plaintiff’s injury “shall be liable only for that
    portion of the total [damages] . . . that is equal to the ratio of such defendant’s
    fault to the total fault attributed to all persons.” Id. § 41-3A-1(B). These two
    categories have come to be identified in New Mexico case law respectively as
    cases involving “successive” tortfeasors and those involving “concurrent”
    tortfeasors. See, e.g., Lujan v. Healthsouth Rehab. Corp., 
    902 P.2d 1025
    , 1028-
    29 (N.M. 1995) (“[Defendants] are not concurrent tortfeasors; they are successive
    tortfeasors by reason of divisible and causally-distinct injuries.”).
    In Lujan, the court listed several factors that are relevant in determining
    whether tortfeasors are successive or concurrent. These factors include:
    1) the identity of time and place between the acts of alleged negligence; 2)
    the nature of the cause of action brought against each defendant; 3) the
    similarity or differences in the evidence relevant to the causes of action; 4)
    the nature of the duties allegedly breached by each defendant; and 5) the
    nature of the harm or damages caused by each defendant.
    - 18 -
    
    Id. at 1029
    . Although those factors have since been criticized, see Lewis v.
    Samson, 
    992 P.2d 282
    , 299-300 (N.M. Ct. App. 1999) (Hartz, J., concurring in
    part, dissenting in part), they remain valid. See Lewis v. Samson, 
    35 P.3d 972
    ,
    984 n.3 (N.M. 2001) (noting criticism of factors but declining to engage in further
    examination of distinction between concurrent and successive tortfeasors).
    Although several factors perhaps could be construed either way, we
    conclude that the first and fifth factors strongly support the district court’s
    conclusion that the Government and San Juan Regional were successive
    tortfeasors. It is uncontroverted that the acts of alleged negligence committed by
    Shiprock Hospital and San Juan Regional occurred days apart from one another
    and in different locations. In light of the fact that hantavirus is a rapidly
    progressing disease, and that Haceesa presented to San Juan Regional with more
    severe symptoms than he did when he visited Shiprock Hospital, we conclude that
    the alleged negligent acts of Shiprock Hospital and San Juan Regional, though
    similar in type (i.e., failure to properly diagnose and treat), were distinct.
    More importantly, we conclude that the nature of the harm caused by each
    of the hospitals was different. In Alberts v. Schultz, 
    975 P.2d 1279
     (N.M. 1999),
    the court recognized the loss-of-chance-of-survival theory. In describing the
    theory, the court noted that “[a] claim for loss of chance is predicated upon the
    negligent denial by a healthcare provider of the most effective therapy for a
    - 19 -
    patient’s presenting medical problem,” and “[t]he negligence may be found in
    such misconduct as an incorrect diagnosis, the application of inappropriate
    treatments, or the failure to timely provide the proper treatment.” 
    Id. at 1282
    .
    The court further noted that “[e]very patient has a certain probability that he or
    she will recover from the presenting medical problem,” and “[u]nder the loss-of-
    chance theory, the health provider’s malpractice has obliterated or reduced those
    odds of recovery that existed before the act of malpractice.” 
    Id.
     (emphasis
    added). The court emphasized that “the patient does not allege that the
    malpractice caused his or her entire injury,” but rather claims “that the health care
    provider’s negligence reduced the chance of avoiding the injury actually
    sustained.” 
    Id. at 1283
     (emphasis added). Consistent with these statements, the
    court noted: “We see no reason at this time to limit lost-chance claims to those
    cases in which the chance of a better result has been utterly lost.” 
    Id. at 1285
    .
    Here, the Government concedes that “Haceesa’s [condition] was far more
    serious when he visited [San Juan Regional] on April 27 and 28, 1998,” than
    when he first visited Shiprock Hospital on April 25, 1998. Govt. Br. at 23-24.
    This admission, in our view, acknowledges that Haceesa had lost a significant
    chance of survival between his visit to Shiprock Hospital and his subsequent
    visits to San Juan Regional. Stated differently, we conclude that the
    Government’s failure to properly diagnose and treat Haceesa on April 25 reduced
    - 20 -
    his chance, to some degree, of recovering from his illness, and that San Juan
    Regional’s subsequent failure to properly diagnose and treat Haceesa on April 27
    and 28 further reduced his chances, thus resulting in separate and divisible
    injuries. 6
    The remaining question is whether the Government is responsible for all of
    the plaintiffs’ damages, including those emanating from San Juan Regional’s
    alleged negligent treatment. Plaintiffs assert that the Government was an
    “original tortfeasor”and thus liable for San Juan Regional’s subsequent medical
    negligence. In support of their assertion, plaintiffs point to the following
    statement by the court in Lewis: “the original tortfeasor is jointly and severally
    liable for the entire harm to the plaintiff, including the original injury and any
    foreseeable enhancement of the injury by medical negligence.” 35 P.3d at 985.
    We reject plaintiffs’ arguments. Lewis involved an original tortfeasor who
    stabbed the plaintiff, and a subsequent tortfeasor who committed medical
    malpractice while endeavoring to treat the injuries resulting from the original tort.
    In discussing the liability of the original tortfeasor, the court was careful to
    6
    For example, assume that Haceesa had a 65% chance of survival at the
    time he was seen and treated at Shiprock Hospital. Further assume that when he
    was seen at San Juan Regional a few days later, he only had a 20% chance of
    survival. Under New Mexico law, the failure of Shiprock Hospital to correctly
    diagnose and treat Haceesa’s illness resulted in a loss of chance of survival of
    45%. San Juan Regional’s subsequent failure to diagnose, assuming it was
    negligent, would have resulted in a separate loss of chance of survival of 20%.
    - 21 -
    emphasize that its discussion was limited to the “narrow class of cases” involving
    “an initial injury caused by tortious conduct and a subsequent enhancement of the
    initial injury caused by foreseeable medical negligence occurring during the
    course of medical treatment for the initial injury.” Id. at 984 (emphasis added).
    Here, in contrast, Haceesa’s initial injury was not caused by the Government, but
    rather by the hantavirus. In other words, the medical negligence allegedly
    committed by San Juan Regional occurred during an attempt to treat the condition
    caused by the hantavirus, not during an attempt somehow to treat the injury (loss
    of chance) caused by the Government’s own medical negligence. 7 Thus, Lewis is
    distinguishable from the instant case, and the district court erred in characterizing
    the Government as an original tortfeasor responsible for all of plaintiffs’
    damages. On remand, it will be necessary for the district court to make findings
    of fact regarding the loss of chance of survival caused by the Government’s
    7
    This point becomes more clear if we hypothesize a third potential
    defendant in the present case, a party whose negligence caused Haceesa’s
    exposure to hantavirus. Assume, for example, that his employer negligently
    provided an unsafe workplace by ordering Haceesa to work in conditions posing a
    high hantavirus infection risk. This hypothetical defendant would be an “original
    tortfeasor” within the ambit of Lewis, and would be responsible not only for
    injuries resulting from his own tortious conduct but also for injuries caused by the
    subsequent medical negligence of the Government and San Juan Regional.
    Removal of the hypothetical original tortfeasor from the picture does not
    transform the first medical provider into an original tortfeasor as those terms are
    used in Lewis.
    - 22 -
    medical negligence and the amount of damages associated exclusively with that
    loss of chance.
    III. JURISDICTION OVER CLAIMS OF THE ESTATE
    The Government contends the district court lacked jurisdiction over the
    claim asserted by the Estate of Haceesa (the Estate). According to the
    Government, the Estate failed to file its claim in federal district court within six
    months of the denial of its administrative claim by the Government. Accordingly,
    the Government argues, “the district court’s award must be limited to claims
    properly filed by [Haceesa’s] wife and daughter.” Aplt. Br. at 16.
    In order to address the Government’s arguments, it is necessary to outline,
    in some detail, the chain of events surrounding the filing of the Estate’s
    administrative claim and its action in federal district court. Following Haceesa’s
    death, three separate administrative claims were filed with the Government (more
    precisely, with the Indian Health Service). The first two claims, one by plaintiff
    Beverly Haceesa and the other by the conservator for Shenoel Haceesa, were filed
    on July 2, 1998. The third administrative claim, by the Estate, was filed on
    October 26, 1998. On January 15, 1999, prior to any formal resolution of any of
    the administrative claims by the Government, plaintiffs Beverly Haceesa,
    appearing individually, and the conservator for Shenoel Haceesa filed this FTCA
    - 23 -
    action against the Government. On April 28, 1999, the Government sent a formal
    notice denying all three administrative claims. 8 On December 3, 1999, plaintiffs
    filed a motion to amend their complaint by interlineation to (1) add Beverly
    Haceesa as personal representative of the Estate, and (2) to add claims for
    Haceesa’s loss of enjoyment of life, pain and suffering, and emotional distress.
    On March 6, 2000, the district court granted plaintiffs’ motion to amend. On
    April 20, 2000, plaintiffs formally filed their amended complaint.
    The FTCA sets forth the following parameters for filing suit. After a tort
    claim against the Government accrues, a claimant has two years to present that
    claim in writing to the appropriate federal agency for consideration. See 
    28 U.S.C. § 2401
    . Following submission of a written claim, a federal agency
    generally has six months to reach a final disposition on the claim. If the federal
    agency denies the claim, the claimant has six months thereafter to file suit in
    federal court. 9 See 
    id.
     If the federal agency fails “to make a final disposition of
    8
    The caption of the letter specifically refers to all three administrative
    claims. Aplt. App. at 147. Plaintiffs nevertheless contend that the letter
    addresses only the first two administrative complaints since, in its body, it refers
    only “to the administrative claims which [were] filed on behalf of Beverly
    Haceesa and Sheldon Wright, as Conservator for Shenoel Haceesa.” 
    Id.
    Plaintiffs’ contention in this regard is erroneous. Given the caption of the letter,
    it is apparent that the letter’s subsequent references to claims filed on behalf of
    Beverly Haceesa refer to both her individual claims and her claims as
    representative of the Estate.
    9
    A tort claim against the Government is “forever barred” if it is not filed
    (continued...)
    - 24 -
    [the] claim within six months,” the claimant may deem the agency’s failure “a
    final denial of the claim” and may proceed with his or her suit under the FTCA
    (again within the six-month period previously noted). 
    28 U.S.C. § 2675
    (a). A
    district court must dismiss a claim under the FTCA if it was filed before the claim
    was denied by the federal agency (either expressly or implicitly). McNeil v.
    United States, 
    508 U.S. 106
    , 113 (1993).
    Applying these principles, we conclude the Estate’s claims were not filed
    within the requisite time parameters. As noted, the Estate filed its administrative
    claim with the Government on October 26, 1998. That claim was officially
    denied by the Government on April 28, 1999. Plaintiffs did not thereafter act
    within six months to either add the Estate as a party or to file a separate action on
    behalf of the Estate. Instead, plaintiffs filed their motion to amend the complaint
    to add the Estate as a party and to add the Estate’s claims for relief on December
    3, 1999, more than a month after the six-month time period for filing suit on
    behalf of the Estate had expired. Assuming that the amendments to plaintiffs’
    complaint related back to the date of the original complaint, see Fed. R. Civ. P.
    15(c) (discussing relation back of amendments), the Estate’s claims would be
    premature under McNeil. More specifically, the original complaint was filed on
    9
    (...continued)
    within the requisite time period. 
    28 U.S.C. § 2401
    (b).
    - 25 -
    January 15, 1999, before the Estate’s administrative claim was denied and fewer
    than six months after the Estate’s administrative claim was filed.
    The only way that the Estate’s claims could be considered valid would be if
    the administrative claims filed on July 2, 1998, by Haceesa’s wife and daughter
    were sufficient to place the Government on notice that they were seeking to assert
    a wrongful death claim on behalf of the Estate. If there are multiple claimants in
    an FTCA case, “each claimant must ‘individually satisfy the jurisdictional
    prerequisite of filing a proper claim.’” Muth v. United States, 
    1 F.3d 246
    , 249
    (4th Cir. 1993) (quoting Frantz v. United States, 
    791 F. Supp. 445
    , 447 (D. Del.
    1992)). Although it appears permissible for multiple claims to be asserted on a
    single claim form, to be valid “the form must give ‘constructive notice’ sufficient
    to warrant [government] investigation of each claim.” Frantz, 
    791 F. Supp. at 447-48
    ; see Barrett v. United States, 
    845 F. Supp. 774
    , 783 (D. Kan. 1994)
    (holding that “plaintiff must show that it gave specific notice of the claimants and
    the nature of the injury as to both causes of action [asserted in complaint], or face
    dismissal for lack of jurisdiction”). In the circumstances here, the question is
    whether the administrative forms filed on July 2, 1998, gave the Government
    specific notice that the claimants intended to assert causes of action on their own
    behalf (e.g., a claim by Beverly Haceesa on her own behalf for loss of
    consortium) and on behalf of the Estate.
    - 26 -
    To decide this question, we first turn to New Mexico tort law. Under the
    New Mexico Wrongful Death Act, the personal representative of a deceased
    person may bring a tort action for wrongful death. 
    N.M. Stat. Ann. § 41-2-3
    .
    Damages may be awarded in such an action for, among other things, the
    decedent’s conscious pain and suffering and medical and related care between the
    date of injury and death. See generally 
    N.M. Stat. Ann. § 41-2-1
    . In such an
    action, the finder of fact may also consider a claim by the decedent’s minor child
    for loss of guidance and counseling. See Romero v. Byers, 
    872 P.2d 840
    , 846
    (N.M. 1994); see also Otero v. City of Albuquerque, 
    965 P.2d 354
    , 357 (N.M. Ct.
    App. 1998) (indicating that it is unclear under New Mexico law whether a minor
    child may bring a separate cause of action, aside from a wrongful death action, to
    recover for loss of guidance and counseling). However, loss of consortium
    damages may not be awarded in such an action to the spouse of the decedent. See
    Romero, 872 P.2d at 842. Instead, the spouse of the decedent must bring a
    separate cause of action in his or her individual capacity to recover such damages.
    See id.
    Turning to the administrative claims, the claim filed by Beverly Haceesa on
    July 2, 1998, briefly described Haceesa’s visit to Shiprock Hospital and the events
    leading to his death. Aplt. App. at 162. When asked on the form to “STATE
    [the] NATURE AND EXTENT OF EACH INJURY OR CAUSE OF DEATH
    - 27 -
    WHICH FORMS THE BASIS OF THE CLAIM,” Beverly Haceesa stated: “Mr.
    Haceesa died due to failure to properly diagnose and treat. Beverly Haceesa, his
    wife, makes a [claim] for loss of spousal support, loss of consortium, loss of love
    and affection, emotional distress and mental anguish.” Id. Later on the same
    form, Beverly Haceesa indicated that she was seeking $4 million in damages for
    “PERSONAL INJURY.” Id. Based upon these responses, we conclude that
    Beverly Haceesa was asserting claims only on her own behalf (e.g., a claim for
    loss of consortium) and was not seeking to recover on behalf of the Estate.
    The remaining claim is the one submitted by the conservator of Shenoel
    Haceesa on July 2, 1998. Aplt. App. at 164. This claim was identical to the
    claim submitted by Beverly Haceesa with one exception. When asked to “STATE
    [the] NATURE AND EXTENT OF EACH INJURY OR CAUSE OF DEATH
    WHICH FORMS THE BASIS OF THE CLAIM,” the conservator stated: “Hardy
    Haceesa died due to failure to properly diagnose and treat. Shenoel Haceesa, his
    four (4) year old daughter, lost her father and hereby makes a claim for loss of
    parental guidance and support; loss of his love affection, emotion distress and
    mental anguish.” Id. In our view, these claims were focused solely on the loss
    suffered by Shenoel Haceesa. Although, as previously noted, New Mexico law
    requires such claims (loss of parental guidance) to be asserted in a wrongful death
    action, nothing in the claim indicates that the conservator was acting on behalf of
    - 28 -
    the Estate, or was otherwise seeking to recover damages for the damages
    personally incurred by Haceesa.
    This conclusion is bolstered when the October 26, 1998 claim filed by the
    Estate is examined. Although the Estate’s claim is substantially similar to the two
    claims filed on July 2, 1998, it differs in two important respects. First, when
    asked to “STATE [the] NATURE AND EXTENT OF EACH INJURY OR CAUSE
    OF DEATH WHICH FORMS THE BASIS OF THE CLAIM,” the claim stated:
    “Hardy Haceesa died due to failure to properly diagnose and treat. The Estate of
    Hardy Haceesa makes a claim for loss of enjoyment of life, pain and suffering,
    emotional distress and mental anguish.” Aplt. App. at 163. Second, when asked
    to state the amount of damages sought, the claim indicated the Estate was seeking
    $1 million for “PERSONAL INJURY” and $4 million for “WRONGFUL
    DEATH.” Id.
    In an attempt to salvage the Estate’s claims, plaintiffs argue that the
    Government’s attorneys led them to believe that the Government would not object
    to plaintiffs’ amending their complaint to add claims on behalf of the Estate. A
    review of the plaintiffs’ supporting evidence, however, suggests that Government
    counsel did nothing wrong and there is no basis for applying equitable tolling in
    this case. In late September 1999, a paralegal working for plaintiffs’ counsel sent
    to Government counsel a draft copy of plaintiffs’ proposed motion to amend.
    - 29 -
    Aplt. App. at 44. On October 6, 1999, Government counsel contacted the
    paralegal and stated “she was not opposed to amendment of the Complaint to
    include the claims of the Estate, but did not believe that the Complaint could be
    amended by interlineation.” Id. Obviously, at the time Government counsel
    agreed in principle to the complaint being amended, the six-month time period for
    the Estate to file suit had not expired (the Estate had until approximately October
    28, 1999, to do so).
    For these reasons, we conclude that the claim of the Estate was not filed
    within the requisite time periods set forth by the FTCA and is thus “forever
    barred.” 
    28 U.S.C. § 2401
    (b). On remand, the district court is directed to dismiss
    the Estate’s claims.
    IV. CONCLUSION
    We AFFIRM the district court’s finding of liability against the Government
    and in favor of Beverly and Shenoel Haceesa, but VACATE the district court’s
    damage award in favor of those plaintiffs and REMAND for recalculation of
    damages consistent with this opinion. We REVERSE the judgment of the district
    court in favor of the Estate of Hardy Haceesa and REMAND with directions to
    dismiss the Estate’s claims.
