    SUMMARY*
    Medicare
    The panel amended the opinion, filed August 10, 2016,
    and vacated the district court’s judgment dismissing qui tam
    relator James Swoben’s third amended complaint, which
    alleged that defendant Medicare Advantage organizations
    submitted false certifications in violation of the False Claims
    Act, and remanded with instructions to afford Swoben leave
    to file a proposed fourth amended complaint.
    The Centers for Medicare & Medicaid Services (“CMS”)
    pays Medicare Advantage organizations fixed monthly
    amounts for each enrollee, and CMS calculates the payment
    for each enrollee based on various “risk adjustment data” as
    reflected in submitted diagnoses codes. Medicare regulations
    require a Medicare Advantage organization to certify that the
    data it submits are “accurate, complete, and truthful.” 42
    C.F.R. § 422.504(l), (l)(2). Swoben alleged that the
    defendant organizations submitted false certifications by
    performing biased retrospective medical record reviews
    designed not to identify erroneously reported diagnosis codes.
    The panel held that the district court abused its discretion
    by denying leave to amend on the ground of futility of
    amendment. The panel held that the theory alleged here –
    that the defendants designed their retrospective review
    procedures to not reveal erroneously reported diagnosis
    codes – adequately alleged that the defendants’ § 422.504(l)

    4            SWOBEN V. UNITED HEALTHCARE
    certifications were false and stated a cognizable legal theory
    under the False Claims Act.
    The panel held that the proposed fourth amended
    complaint alleged sufficient factual matter to satisfy Fed. R.
    Civ. P. 8, 9(b) and 12(b)(6), or may be amended to do so.
    The panel held that with respect to defendants United
    Healthcare and HealthCare Partners, the allegations
    adequately identified the details of the misconduct charged,
    and afforded each defendant notice of its alleged role in a
    fraudulent scheme; and therefore, satisfied Rule 9(b). The
    panel further held that with respect to defendants Aetna,
    WellPoint and Health Net, the allegations lacked sufficient
    detail to satisfy Rule 9(b), but Swoben should be afforded
    leave to amend to cure this deficiency.
    The panel held that the district court also abused its
    discretion by denying leave to amend based on undue delay.
    The panel held that leave to amend was proper in this case
    where the litigation against the defendants was at an early
    stage, Swoben did not seek to assert a new legal theory, and
    this was Swoben’s first attempt to cure deficiencies in his
    pleadings.

    ORDER
    Judges Reinhardt and Nguyen have voted to deny
    appellees’ petition for rehearing en banc, and Judge Fisher
    has so recommended.
    The full court has been advised of the petition for
    rehearing en banc and no judge has requested a vote on
    whether to rehear the matter en banc. See Fed. R. App. P. 35.
    The petition for rehearing en banc is DENIED.
    The opinion, filed August 10, 2016 and published at
    
    832 F.3d 1084
    , is AMENDED. An amended opinion is filed
    concurrently with this order.
    Further petitions for rehearing may be filed.
    OPINION
    FISHER, Circuit Judge:
    The Centers for Medicare & Medicaid Services (CMS),
    administrator of the federal Medicare program, pays
    Medicare Advantage organizations fixed monthly amounts
    for each enrollee. CMS calculates the payment for each
    enrollee based on various “risk adjustment data,” such as an
    enrollee’s demographic profile and the enrollee’s health
    status, as reflected in the medical diagnosis codes associated
    with healthcare the enrollee receives. These diagnosis codes
    (also known as encounter data) are reported by Medicare
    Advantage organizations to CMS. Because Medicare
    SWOBEN V. UNITED HEALTHCARE                    7
    Advantage organizations have a financial incentive to
    exaggerate an enrollee’s health risks by reporting diagnosis
    codes that may not be supported by the enrollee’s medical
    records, Medicare regulations require a Medicare Advantage
    organization, as an express condition of receiving payment,
    to “certify (based on best knowledge, information, and belief)
    that the [risk adjustment] data it submits . . . are accurate,
    complete, and truthful.” 42 C.F.R. § 422.504(l), (l)(2).
    Qui tam relator James Swoben alleges Medicare
    Advantage organizations United Healthcare, Aetna,
    WellPoint and Health Net, and physician group HealthCare
    Partners, submitted false certifications under this provision,
    in violation of the False Claims Act, by conducting
    retrospective reviews of medical records designed to identify
    and report only under-reported diagnosis codes (diagnosis
    codes erroneously not submitted to CMS despite adequate
    support in an enrollee’s medical records), not over-reported
    codes (codes erroneously submitted to CMS despite the
    absence of adequate record support). The district court
    denied Swoben leave to file a proposed fourth amended
    complaint, citing futility of amendment and undue delay. We
    hold the district court abused its discretion.
    First, the court erred by concluding amendment would be
    futile. Swoben’s proposed fourth amended complaint asserts
    a cognizable legal theory. CMS has long made clear that,
    under § 422.504(l), Medicare Advantage organizations have
    “an obligation to undertake ‘due diligence’ to ensure the
    accuracy, completeness, and truthfulness” of the risk
    adjustment data they submit to CMS and “will be held
    responsible for making good faith efforts to certify the
    accuracy, completeness, and truthfulness” of these data.
    Medicare+Choice Program, 65 Fed. Reg. 40,170, 40,268
    8            SWOBEN V. UNITED HEALTHCARE
    (June 29, 2000). When, as alleged here, Medicare Advantage
    organizations design retrospective reviews of enrollees’
    medical records deliberately to avoid identifying erroneously
    submitted diagnosis codes that might otherwise have been
    identified with reasonable diligence, they can no longer
    certify, based on best knowledge, information and belief, the
    accuracy, completeness and truthfulness of the data submitted
    to CMS. This is especially true when, as alleged here, they
    were on notice – based on audits conducted by CMS – that
    their data likely included a significant number of erroneously
    reported diagnosis codes. The allegations in Swoben’s
    proposed fourth amended complaint also partly satisfy Rules
    8 and 9(b) of the Federal Rules of Civil Procedure. With
    respect to defendants United Healthcare and HealthCare
    Partners, the allegations adequately identify “the who, what,
    when, where, and how of the misconduct charged,” Ebeid ex
    rel. United States v. Lungwitz, 
    616 F.3d 993
    , 998 (9th Cir.
    2010) (quoting Vess v. Ciba-Geigy Corp. USA, 
    317 F.3d 1097
    , 1106 (9th Cir. 2003)) (internal quotation marks
    omitted), and afford each defendant notice of its alleged role
    in a fraudulent scheme. With respect to defendants Aetna,
    WellPoint and Health Net, the allegations lack sufficient
    detail to satisfy Rule 9(b), but Swoben should be afforded
    leave to amend to cure this deficiency.
    Second, the district court abused its discretion by denying
    leave to amend based on undue delay. Undue delay by itself
    is insufficient to justify denying leave to amend, and the
    record here does not support any additional ground – such as
    prejudice or bad faith – that would justify the denial. See
    Owens v. Kaiser Found. Health Plan, Inc., 
    244 F.3d 708
    ,
    712–13 (9th Cir. 2001). Leave to amend is proper here given
    the litigation against these defendants is at an early stage,
    SWOBEN V. UNITED HEALTHCARE                    9
    Swoben does not seek to assert a new legal theory and this is
    Swoben’s first attempt to cure deficiencies in his pleadings.
    BACKGROUND
    I. The Medicare Advantage Program
    Medicare beneficiaries have the option of receiving
    benefits through private health plans as an alternative to the
    traditional fee-for-service Medicare program. Under this
    option, known as Medicare Advantage or Medicare Part C,
    the government pays Medicare Advantage organizations a
    capitated (per enrollee) amount to provide medical benefits.
    The capitated amount is a fixed monthly payment regardless
    of the volume of services an enrollee uses.
    The government adjusts the monthly payments to
    Medicare Advantage organizations to reflect the health status
    of their enrollees. See 42 U.S.C. § 1395w-23(a)(1)(C)(i),
    (a)(3); 42 C.F.R. § 422.308(c)(2). This ensures Medicare
    Advantage “organizations are paid appropriately for their
    plan enrollees (that is, less for healthier enrollees and more
    for less healthy enrollees).” Establishment of the Medicare
    Advantage Program, 70 Fed. Reg. 4588, 4657 (Jan. 28, 2005).
    The risk adjustment methodology relies on enrollee
    diagnoses. See Policy and Technical Changes to the
    Medicare Advantage and the Medicare Prescription Drug
    Benefit Programs, 74 Fed. Reg. 54,634, 54,673 (Oct. 22,
    2009). Physicians and other health care providers submit
    diagnosis codes to the Medicare Advantage organizations,
    which in turn submit them to CMS. See 
    id. at 54,674.
    These
    diagnosis codes contribute to an enrollee’s risk score, which
    is used to adjust a base payment rate. See 
    id. Each diagnosis
    code submitted must be supported by a properly documented
    10               SWOBEN V. UNITED HEALTHCARE
    medical record. See 42 U.S.C. §§ 1395l(e), 1395y(a)(1)(A);
    42 C.F.R. § 422.310(d); Contract Year 2015 Policy and
    Technical Changes to the Medicare Advantage and the
    Medicare Prescription Drug Benefit Programs, 79 Fed. Reg.
    29,844, 29,923 (May 23, 2014) (“CMS has required for many
    years that diagnoses that [Medicare Advantage] organizations
    submit for payment be supported by medical record
    documentation.”).
    “Since there is an incentive for [Medicare Advantage]
    organizations to potentially over-report diagnoses so that they
    can increase their payment, [CMS] audits plan-submitted
    diagnosis data a few years later to ensure they are supported
    by medical record documentation.” Contract Year 2015
    Policy and Technical Changes to the Medicare Advantage
    and the Medicare Prescription Drug Benefit Programs,
    79 Fed. Reg. 1918, 2001 (Jan. 10, 2014). These risk
    adjustment data validation (RADV) audits review selected
    medical records to determine whether they support the
    diagnoses reported by Medicare Advantage organizations.
    See id.1
    As a further bulwark against fraud, Medicare Advantage
    organizations must certify the accuracy, completeness and
    1
    Initially, when conducting RADV audits, CMS recouped overpayments
    solely with respect to the sampled beneficiaries. More recently, CMS has
    implemented a procedure through which the payment error rate calculated
    for the sampled beneficiaries in the audits is extrapolated to the contract
    population as a whole. See CMS, Medicare Advantage Risk Adjustment
    Data Validation Audits Fact Sheet 1, 3 (updated Dec. 11, 2015),

    truthfulness of the data they provide to CMS, including risk
    adjustment data, as a condition to receiving payment:
    As a condition for receiving a monthly
    payment under subpart G of this part, the
    [Medicare Advantage] organization agrees
    that its chief executive officer (CEO), chief
    financial officer (CFO), or an individual
    delegated the authority to sign on behalf of
    one of these officers, and who reports directly
    to such officer, must request payment under
    the contract on a document that certifies
    (based on best knowledge, information, and
    belief) the accuracy, completeness, and
    truthfulness of relevant data that CMS
    requests.     Such data include specified
    enrollment information, encounter data and
    other information that CMS may specify.
    42 C.F.R. § 422.504(l) (emphasis added).2 Specifically, a
    Medicare Advantage organization “must certify (based on
    best knowledge, information, and belief) that the [risk
    adjustment] data it submits under § 422.310 are accurate,
    complete, and truthful.” 
    Id. § 422.504(l)(2).
    A Medicare Advantage organization is also required to
    “[a]dopt and implement an effective compliance program,
    which must include measures that prevent, detect, and correct
    non-compliance with CMS’ program requirements.” 
    Id. 2 This
    regulation has been in force, in substantially the same form, since
    2000. See 42 C.F.R. § 422.502(l) (2000).
    12             SWOBEN V. UNITED HEALTHCARE
    § 422.503(b)(4)(vi).3 In addition, although Medicare
    Advantage organizations generally submit data to CMS
    shortly after services are provided, the regulations also allow
    for data submissions after the payment year. See 
    id. § 422.310(g).
    CMS uses these data to “recalculate[] the risk
    factors for affected individuals to determine if adjustments to
    payments are necessary.” 
    Id. § 422.310(g)(2)
    In light of these provisions, Medicare Advantage
    organizations may, but are not required to, conduct
    retrospective reviews of their enrollees’ medical records to
    ensure the accuracy of the diagnosis codes they have
    provided to CMS. See CMS, 2008 Risk Adjustment Data
    Technical Assistance For Medicare Advantage Organizations
    Participant Guide § 7.7.
    Certification under § 422.504(l) has always required due
    diligence and good faith. When CMS adopted the “best
    knowledge, information, and belief” standard in 2000, it
    explained in the preamble to the regulation that Medicare
    Advantage organizations “cannot reasonably be expected to
    know that every piece of data is correct,” so “simple mistakes
    will not result in sanctions.” Medicare+Choice Program,
    65 Fed. Reg. 40,170, 40,268 (June 29, 2000). But
    § 422.504(l) does not require actual knowledge that the data
    supplied to CMS are false. Rather, as under the False Claims
    Act, a certification is false under § 422.504(l) when the
    Medicare Advantage organization has actual knowledge of
    the falsity of the risk adjustment data or demonstrates either
    “reckless disregard” or “deliberate ignorance” of the truth or
    3
    This requirement has been on the books, in similar form, since 2005.
    See 42 C.F.R. § 422.503(b)(4)(vi)(F), (G) (2005); 
    id. § 422.503(b)(4)(vi)
    (2010).
    SWOBEN V. UNITED HEALTHCARE                    13
    falsity of the data. 
    Id. Thus, Medicare
    Advantage
    organizations “have an obligation to undertake ‘due
    diligence’ to ensure the accuracy, completeness, and
    truthfulness of encounter data submitted to [CMS]” and “will
    be held responsible for making good faith efforts to certify
    the accuracy, completeness, and truthfulness of encounter
    data submitted.” 
    Id. In 2014,
    CMS considered but ultimately decided not to
    finalize a proposed rule that would have altogether prohibited
    Medicare Advantage organizations from performing one-
    sided retrospective reviews. Under the proposed regulation:
    medical record reviews conducted by [a
    Medicare Advantage] organization cannot be
    designed only to identify diagnoses that would
    trigger additional payments by CMS to the . . .
    organization; and medical record review
    methodologies must be designed to identify
    errors in diagnoses submitted to CMS as risk
    adjustment data, regardless of whether the
    data errors would result in positive or negative
    payment adjustments.
    79 Fed. Reg. at 2000. Although CMS decided not to finalize
    the proposed rule, see 
    id. at 29,926,
    it reiterated that it has
    “always expected that [a Medicare Advantage] organization
    . . . implement, during the routine course of business,
    appropriate payment evaluation procedures in order to meet
    the requirement of certifying the data they submit to CMS for
    purposes of payment,” 
    id. at 29,923.
    CMS explained:
    [Medicare Advantage] organizations . . . are
    responsible for ensuring that payment data
    14              SWOBEN V. UNITED HEALTHCARE
    they submit to CMS are accurate, truthful, and
    complete (based on best knowledge,
    information, and belief), and are expected to
    have effective and appropriate payment
    evaluation procedures and effective
    compliance programs as a way to avoid
    receiving or retaining overpayments. Thus, at
    a minimum, reasonable diligence would
    include proactive compliance activities
    conducted in good faith by qualified
    individuals to monitor for the receipt of
    overpayments.
    
    Id. CMS added,
    “[i]f the requirement to report and return
    overpayments applied only to situations where the [Medicare
    Advantage] organization . . . has actual knowledge of the
    existence of an overpayment, then these entities could easily
    avoid returning improperly received payments.” 
    Id. at 29,924.4
    Although these 2014 events postdate the allegations
    in Swoben’s pleadings, which cover the years between 2005
    and 2012, they are consistent with the regulatory
    requirements that have existed since 2000.
    4
    Also in 2014, CMS adopted a regulation stating that a Medicare
    Advantage organization “has identified an overpayment when [it] has
    determined, or should have determined through the exercise of reasonable
    diligence, that [it] has received an overpayment,” 42 C.F.R. § 422.326(c),
    and for this purpose an “overpayment” includes a previously submitted
    medical diagnosis code that is not properly supported by a medical record,
    see 79 Fed. Reg. at 29,921 (stating “a risk adjustment diagnosis that has
    been submitted for payment but is found to be invalid because it does not
    have supporting medical record documentation would result in an
    overpayment”).
    SWOBEN V. UNITED HEALTHCARE                    15
    II. Procedural History
    Swoben filed an initial complaint in this action in 2009.
    His first amended complaint added claims against United
    Healthcare. He filed a second amended complaint in 2010.
    In 2011, he filed a third amended complaint, adding claims
    against HealthCare Partners, Aetna, WellPoint and Health
    Net. In accordance with the False Claims Act, Swoben filed
    each of these pleadings under seal. See 31 U.S.C.
    § 3730(b)(2).
    The gist of Swoben’s complaint is that the defendants –
    Medicare Advantage organizations United Healthcare, Aetna,
    WellPoint and Health Net, and HealthCare Partners, a
    physician group providing health care services to these
    organizations’ enrollees in exchange for a percentage of the
    organizations’ capitated payments – performed biased
    retrospective medical record reviews. According to Swoben,
    retrospective reviews by Medicare Advantage organizations
    typically should identify (and report to CMS) two types of
    errors in the risk adjustment data previously submitted:
    (1) diagnosis codes supported by an enrollee’s medical
    records but not previously submitted to CMS (under-
    reporting errors); and (2) diagnosis codes previously
    submitted to CMS but not supported by the enrollee’s
    medical records (over-reporting errors). Identifying and
    reporting the first type of error is favorable to the Medicare
    Advantage organization; identifying and reporting the second
    type of error is unfavorable. Swoben alleges the defendants
    conducted one-sided retrospective reviews designed to
    identify (and report to CMS) solely the first type of error. He
    alleges these reviews were designed to exaggerate enrollees’
    health risks and cause CMS to make inflated capitated
    payments to the defendants. These actions, Swoben alleges,
    16           SWOBEN V. UNITED HEALTHCARE
    rendered the defendants’ periodic certifications under
    § 422.504(l) false, in violation of the False Claims Act,
    31 U.S.C. § 3729(a)(1).
    Specifically, Swoben alleges the defendants’ retrospective
    reviews were biased in several respects. For instance, he
    alleges each of the defendants retained coding companies or
    purchased specialized software to perform retrospective
    reviews of the medical charts of tens of thousands of their
    patients with severe illnesses but “concealed from the coders
    the diagnosis codes that had been previously submitted to the
    Government.” Fourth Am. Compl. ¶¶ 12, 16–17. As a
    consequence, “the results of the coders’ reviews did not
    identify the diagnosis codes unsupported by proper
    documentation of the reviewed medical charts that had been
    previously submitted to the Government.” Fourth Am.
    Compl. ¶¶ 13, 17. Swoben alleges the defendants engaged in
    these activities beginning in 2005. Fourth Am. Compl. ¶¶ 12,
    16.
    Swoben also alleges United Healthcare instructed its
    medical providers, including HealthCare Partners, to review
    the medical charts of selected patients to determine whether
    those charts supported specific diagnoses that had not
    previously been reported to CMS. Fourth Am. Compl. ¶ 14.
    The medical providers reported the additional diagnosis codes
    supported by the records “but made no attempt to determine
    or report those previously reported diagnosis codes that were
    unsupported by properly documented medical charts that
    were reviewed.” Fourth Am. Compl. ¶ 14. Swoben alleges
    United Healthcare and HealthCare Partners engaged in this
    activity from approximately 2005 to 2007. Fourth Am.
    Compl. ¶ 14.
    SWOBEN V. UNITED HEALTHCARE                           17
    Swoben further alleges the defendants used a template to
    report the results of their retrospective reviews to CMS that
    allowed coders to enter any additional diagnosis codes
    identified by the reviews but “did not permit the entry of
    information indicating what previously submitted [diagnosis]
    codes should be withdrawn.” Fourth Am. Compl. ¶ 23.
    Swoben alleges the defendants used the faulty template from
    approximately 2006 to 2012. Fourth Am. Compl. ¶ 24. He
    asserts the defendants were involved in the development of
    the template and were aware of its shortcomings. Fourth Am.
    Compl. ¶¶ 22, 27.
    Swoben also alleges CMS conducted annual RADV
    audits of sample medical charts for United Healthcare, Aetna,
    WellPoint and Health Net. Fourth Am. Compl. ¶ 25. He
    alleges each of these Medicare Advantage organizations “had
    RADV audit error rates well in excess of 20%, reflecting that
    more than 20% of [their] diagnosis codes submitted to CMS
    were not supported by properly documented medical charts.”
    Fourth Am. Compl. ¶ 25.5 Swoben alleges the over-reporting
    error rate found in these audits of representative medical
    records placed the defendants on notice that the risk
    adjustment data they more broadly submitted to CMS also
    contained significant over-reporting errors. Fourth Am.
    Compl. ¶ 25.
    Swoben alleges the defendants’ practices rendered their
    § 422.504(l) certifications false and fraudulent. He alleges
    they submitted false claims by attesting to the accuracy of
    their risk adjustment data even though they knowingly
    5
    Swoben alleges the RADV audits showed a high percentage of over-
    reporting errors. His allegations do not address whether the RADV audits
    also identified under-reporting errors.
    18           SWOBEN V. UNITED HEALTHCARE
    designed and performed retrospective reviews to conceal and
    not withdraw previously submitted diagnosis codes that were
    unsupported by retrospectively reviewed medical records.
    Fourth Am. Compl. ¶ 27. He alleges, moreover, that the
    defendants knew their certifications were false because they
    (1) helped develop the reporting template and knew the
    template would not capture over-reporting errors identified by
    retrospective reviews; (2) had RADV audit over-reporting
    error rates in excess of 20 percent, placing them on notice that
    “a similar percentage of medical charts that were
    retrospectively reviewed should have resulted in [diagnosis]
    codes being withdrawn as unsupported by the medical
    charts”; and (3) designed their retrospective reviews to avoid
    identifying or reporting unsupported diagnosis codes that
    should have been withdrawn. Fourth Am. Compl. ¶ 27.
    In 2012, the United States intervened in the action as to
    Swoben’s claims against certain defendants not relevant here.
    In January 2013, the United States declined to intervene as to
    the defendants who are parties to this appeal (collectively,
    “the defendants”). The district court ordered the complaints
    unsealed and served on the defendants. In June 2013, after
    the district court issued an initial scheduling and case
    management order, the newly served defendants moved to
    dismiss Swoben’s claims, arguing his third amended
    complaint failed to satisfy Rules 8, 9(b) and 12(b)(6) of the
    Federal Rules of Civil Procedure.
    In his opposition to the defendants’ motions, Swoben did
    not defend the third amended complaint. Instead, he advised
    the court he would voluntarily dismiss his claims under state
    law and would seek leave to amend his complaint with
    respect to his claims under the False Claims Act. The district
    court ordered Swoben to file a declaration describing “in
    SWOBEN V. UNITED HEALTHCARE                     19
    detail the proposed Fourth Amended Complaint and why such
    an amendment would not be futile or denied due to evidence
    of a lack of diligence or undue delay.” As directed, Swoben
    filed a declaration of counsel setting out the additional
    allegations he would include in a fourth amended complaint.
    In a July 2013 order, the district court dismissed the third
    amended complaint with prejudice, concluding Swoben failed
    to allege a claim under the False Claims Act with
    particularity as required by Rule 9(b). The court denied leave
    to amend, citing both futility of amendment and undue delay.
    The court entered final judgment, and Swoben timely
    appealed. He does not challenge dismissal of the third
    amended complaint but contends the district court abused its
    discretion by denying leave to amend.
    After hearing oral argument, we asked the parties to
    submit supplemental briefing to address when conducting
    retrospective medical record reviews designed to identify
    only diagnoses that would trigger additional payments by
    CMS, not errors that would result in negative payment
    adjustments, would cause a certification to be false for
    purposes of § 422.504(l) and the False Claims Act. The
    parties filed briefs addressing this question, and the
    Department of Justice, representing the United States as
    amicus curiae, filed a brief supporting Swoben.
    STANDARD OF REVIEW
    We review the denial of leave to amend for an abuse of
    discretion, see United States ex rel. Lee v. Corinthian Colls.,
    
    655 F.3d 984

    Info. Servs., LLC, 
    629 F.3d 876
    , 893 (9th Cir. 2010).
    20              SWOBEN V. UNITED HEALTHCARE
    DISCUSSION
    The district court denied leave to amend on two
    independent grounds – futility of amendment and undue
    delay. We address these in turn.
    I. Amendment Would Not Be Futile
    The district court denied leave to amend in part on the
    ground that amendment would have been futile. Accordingly,
    we address whether Swoben’s proposed fourth amended
    complaint, or a further amended pleading, would be adequate
    to survive a motion to dismiss.
    A. The Proposed Fourth Amended Complaint
    Adequately States a Cognizable Legal Theory
    The parties dispute whether Swoben’s proposed fourth
    amended complaint alleges a cognizable legal theory.
    1. The False Claims Act imposes liability in part on “any
    person who . . . knowingly presents, or causes to be
    presented, a false or fraudulent claim for payment or
    approval,” 31 U.S.C. § 3729(a)(1)(A), or “knowingly makes,
    uses, or causes to be made or used, a false record or statement
    material to a false or fraudulent claim,” 
    id. § 3729(a)(1)(B).6
    “In an archetypal qui tam False Claims action, such as where
    a private company overcharges under a government contract,
    6
    In addition to these False Claims Act provisions, the United States, as
    amicus curiae, argues the defendants’ conduct violates § 3729(a)(1)(G),
    known as the “reverse false claims” provision. Swoben, however, did not
    rely on that provision in his opening and reply briefs. We therefore do not
    address it here.
    SWOBEN V. UNITED HEALTHCARE                           21
    the claim for payment is itself literally false or fraudulent.”
    United States ex rel. Hendow v. Univ. of Phoenix, 
    461 F.3d 1166
    , 1170 (9th Cir. 2006). As relevant here, however, “a
    claim under the False Claims Act can be false where a party
    merely falsely certifies compliance with a statute or
    regulation as a condition to government payment.” 
    Id. at 1171.
    Under a false certification theory, “it is the false
    certification of compliance which creates liability when
    certification is a prerequisite to obtaining a government
    benefit.” 
    Id. (alteration omitted)
    (quoting United States ex
    rel. Hopper v. Anton, 
    91 F.3d 1261
    , 1266 (9th Cir. 1996)).
    The essential elements of a false certification claim are: “(1) a
    false statement or fraudulent course of conduct, (2) made with
    scienter, (3) that was material, causing (4) the government to
    pay out money or forfeit moneys due.” 
    Id. at 1174.7
    Proof of
    damage to the government is not required. See Bly-Magee v.
    California, 
    236 F.3d 1014
    , 1017 (9th Cir. 2001); United
    States ex rel. Hagood v. Sonoma Cty. Water Agency, 
    929 F.2d 1416
    , 1421 (9th Cir. 1991); Claire M. Sylvia, The False
    Claims Act: Fraud Against the Government §§ 4:2, 4:3
    (2015).
    The defendants challenge Swoben’s theory that the
    manner in which they designed and conducted their
    retrospective reviews rendered their certifications under
    § 422.504(l) false. They contend:
    During the time period alleged in the
    complaint, no statute, regulation, or guidance
    7
    The defendants’ briefing challenges only the first and second of these
    elements here. Accordingly, for purposes of our analysis, we assume
    Swoben’s proposed fourth amended complaint satisfies the third and
    fourth elements.
    22           SWOBEN V. UNITED HEALTHCARE
    from CMS indicated that a certification could
    only be “accurate, complete, and truthful” if
    [a Medicare Advantage] plan validated for
    itself that the millions of diagnosis codes
    submitted to it by third-party providers were
    supported by the underlying medical charts –
    i.e., that the plan was required to attest to the
    accuracy of someone else’s work. Nor did
    any authority indicate that a plan was obliged
    to undertake affirmative steps to unearth
    potentially unsupported codes before it could
    certify the third-party risk adjustment data
    based on its “best knowledge, information,
    and belief.”
    Joint Suppl. Br. 1. These arguments are unpersuasive for two
    distinct reasons.
    First, the defendants mischaracterize Swoben’s theory of
    the case.       Swoben does not allege the defendants’
    certifications are false merely because they passively
    forwarded to CMS unsupported diagnosis codes they received
    from their medical providers. That type of conduct would not
    necessarily result in false § 422.504(l) certifications. As
    CMS made clear in the 2000 preamble, Medicare Advantage
    organizations “cannot reasonably be expected to know that
    every piece of data is correct, nor is that the standard that
    [CMS and the Department of Justice] believe is reasonable to
    enforce.” 65 Fed. Reg. at 40,268. “[S]imple mistakes will
    not result in sanctions.” 
    Id. Instead, Swoben
    alleges the
    defendants took affirmative steps to generate and report
    skewed data. Even in the face of “RADV audit error rates
    well in excess of 20%” (Fourth Am. Compl. ¶ 25), they
    “conceived, planned and conducted the retrospective reviews
    SWOBEN V. UNITED HEALTHCARE                     23
    by not causing the previously submitted diagnosis codes that
    were unsupported by the retrospective reviews to be corrected
    and withdrawn from the Government,” doing so “with the
    knowledge and intent that the retrospective reviews would
    only increase, and not decrease, the number of diagnoses, and
    thus their respective risk scores in order to increase capitated
    payments paid by the Government” (Fourth Am. Compl.
    ¶ 19). The defendants’ attempts to portray themselves as the
    passive victims of their providers’ errors wholly misstates
    Swoben’s legal theory, which focuses on the defendants’ own
    conduct in allegedly conceiving, directing and conducting
    retrospective reviews designed to identify only favorable
    reporting errors.
    Second, the defendants’ contention that, during the
    relevant time period between 2005 and 2012, there was no
    “authority [to] indicate that a [Medicare Advantage] plan was
    obliged to undertake affirmative steps to unearth potentially
    unsupported codes before it could certify the third-party risk
    adjustment data based on its ‘best knowledge, information,
    and belief’” is unpersuasive. When it adopted the “best
    knowledge, information, and belief” standard in 2000, CMS
    made clear this was the same standard as the one establishing
    liability under the False Claims Act – i.e., that it encompasses
    not only actual knowledge of falsity but also reckless
    disregard and deliberate ignorance. See 65 Fed. Reg. at
    40,268; see also 31 U.S.C. § 3729(b)(1)(A) (False Claims
    Act). As we have explained in describing this standard under
    the False Claims Act:
    In defining knowingly, Congress attempted
    “to reach what has become known as the
    ‘ostrich’ type situation where an individual
    has ‘buried his head in the sand’ and failed to
    24           SWOBEN V. UNITED HEALTHCARE
    make simple inquiries which would alert him
    that false claims are being submitted.” S.
    Rep. No. 99-345, at 21 (1986), as reprinted in
    1986 U.S.C.C.A.N. 5266, 5286. Congress
    adopted “the concept that individuals and
    contractors receiving public funds have some
    duty to make a limited inquiry so as to be
    reasonably certain they are entitled to the
    money they seek.” 
    Id. at 20;
    see also 
    id. at 7
           (discussing the importance of individual
    responsibility because the government has
    limited resources to police fraud). “While the
    Committee intends that at least some inquiry
    be made, the inquiry need only be ‘reasonable
    and prudent under the circumstances.’” 
    Id. at 21.
    United States v. Bourseau, 
    531 F.3d 1159
    , 1168 (9th Cir.
    2008); see also Universal Health Servs., Inc. v. U.S. ex rel.
    Escobar, 
    136 S. Ct. 1989
    , 2000 (2016) (holding “half-truths
    – representations that state the truth only so far as it goes,
    while omitting critical qualifying information – can be
    actionable misrepresentations” under the False Claims Act).
    Thus, as CMS made clear, Medicare Advantage
    organizations have always had “an obligation to take steps to
    ensure the accuracy, completeness, and truthfulness of the
    encounter data” and “an obligation to undertake ‘due
    diligence’ to ensure the accuracy, completeness, and
    truthfulness of encounter data submitted to [CMS].” 65 Fed.
    Reg. at 40,268. CMS made perfectly clear that Medicare
    Advantage organizations would be “held responsible for
    making good faith efforts to certify the accuracy,
    completeness, and truthfulness of encounter data submitted.”
    SWOBEN V. UNITED HEALTHCARE                     25
    
    Id. Indeed, CMS
    expressly rejected the argument that
    Medicare Advantage organizations “should not be required to
    certify the accuracy of the encounter data they receive from
    third parties.” 
    Id. The defendants’
    contention that they were
    under no obligation to take affirmative steps to address errors
    also ignores § 422.503, which since 2005 has required
    Medicare Advantage organizations to have effective
    compliance programs in place, including “[p]rocedures for
    internal monitoring and auditing” and for “ensuring
    prompt response to detected offenses.”             42 C.F.R.
    § 422.503(b)(4)(vi), (vi)(F), (vi)(G) (2005).
    In light of these authorities, we hold that when, as alleged
    here, Medicare Advantage organizations design retrospective
    reviews of enrollees’ medical records deliberately to avoid
    identifying erroneously submitted diagnosis codes that might
    otherwise have been identified with reasonable diligence,
    they can no longer certify, based on best knowledge,
    information and belief, the accuracy, completeness and
    truthfulness of the data submitted to CMS. This is especially
    true, when, as alleged here, they were on notice that their data
    included a significant number of erroneously reported
    diagnosis codes. We do not see how a Medicare Advantage
    contractor who has engaged in such conduct can in good faith
    certify that it believes the resulting risk adjustment data
    reported to CMS are accurate, complete and truthful. As the
    government argues in its amicus brief, when a Medicare
    Advantage plan “has implemented record-review procedures
    specifically designed not to reveal unsupported diagnosis
    codes – the plan’s certification under § 422.504(l) is ‘false or
    fraudulent’ under 31 U.S.C. § 3729(a)(1)(A) & (B).” Br.
    United States as Amicus Curiae 4.
    26           SWOBEN V. UNITED HEALTHCARE
    By holding that one-sided retrospective reviews can result
    in false certifications under § 422.504(l), we do not suggest
    that they necessarily always do. The “best knowledge,
    information, and belief” standard under § 422.504(l) prohibits
    only a “reckless disregard” or “deliberate ignorance” of the
    truth or falsity of the risk adjustment data submitted to CMS.
    We do not in this opinion attempt to define the parameters of
    these requirements. We hold only that the theory alleged here
    – that the defendants designed their retrospective review
    procedures to not reveal unsupported diagnosis codes,
    allegedly for no other reason than to avoid reporting that
    information to the government – states a cognizable legal
    theory under the False Claims Act. That the defendants
    allegedly did so in spite of RADV audit errors rates of 20
    percent or more only strengthens Swoben’s claims.
    We also do not intend to suggest that the practice of
    concealing previously submitted diagnosis codes from coders
    conducting retrospective reviews is necessarily a suspect
    practice. On the contrary, blind coding may help ensure the
    integrity of a retrospective review: if reviewers are told in
    advance which codes were submitted to CMS, they may have
    an especially strong incentive to find support for those codes
    in the records under review.
    But blind coding cannot be squared with the good faith
    required by § 422.504(l) when it is employed as a means of
    avoiding or concealing over-reporting errors. If Medicare
    Advantage organizations acquire the codes identified by
    retrospective coders, compare them to the codes previously
    submitted to CMS, identifying both under- and over-reporting
    errors, but withhold information about the over-reporting
    errors from CMS, this would result in a false certification.
    The same is true when a Medicare Advantage organization
    SWOBEN V. UNITED HEALTHCARE                     27
    undertakes comprehensive blind coding but then runs a
    unidirectional comparison with the previously submitted
    codes to reveal only under-reporting errors. As the
    government explains, the use of blind coding cannot excuse
    failing to “check whether diagnosis codes previously
    submitted to CMS were included on the list of diagnoses
    found by the reviewers to be supported by the medical
    records.” Br. United States as Amicus Curiae 15. In the first
    example, in which a Medicare Advantage organization
    withholds known over-reporting errors from CMS, the
    organization has actual knowledge that the data are false. In
    the second example, where the organization turns a blind eye
    to the over-reporting errors, it exhibits reckless disregard and
    deliberate ignorance toward the truth or falsity of the data
    submitted to CMS. Both examples show a lack of diligence
    and an absence of good faith. On the other hand, if through
    reasonable diligence the comparison between the codes
    identified by the retrospective reviewers and the codes
    previously submitted to CMS is capable of identifying only
    under-reporting errors, we assume this would not result in
    false certifications under current CMS regulations. The due
    diligence standard requires only reasonable efforts.
    In sum, Swoben has alleged a cognizable legal theory.
    2. The defendants’ arguments to the contrary are not
    persuasive.
    The defendants argue their certifications cannot have been
    false because they did not know of any specific unsupported
    diagnosis codes in the data they submitted to CMS. Joint
    Suppl. Br. 4. As explained, however, neither the “best
    knowledge, information, and belief” standard under
    § 422.504(l) nor the scienter element of the False Claims Act
    28           SWOBEN V. UNITED HEALTHCARE
    requires actual knowledge of falsity. Under the False Claims
    Act,
    the terms “knowing” and “knowingly” –
    (A) mean that a person, with respect to
    information – (i) has actual knowledge of the
    information; (ii) acts in deliberate ignorance
    of the truth or falsity of the information; or
    (iii) acts in reckless disregard of the truth or
    falsity of the information; and (B) require no
    proof of specific intent to defraud.
    31 U.S.C. § 3729(b)(1). Section 422.504(l) adopts precisely
    the same standard. See 65 Fed. Reg. at 40,268. And this
    standard reaches “what has become known as the ostrich type
    situation where an individual has buried his head in the sand
    and failed to make simple inquiries which would alert him
    that false claims are being submitted.” 
    Bourseau, 531 F.3d at 1168
    (quoting S. Rep. No. 99-345, at 21) (internal
    quotation marks omitted). Although the False Claims Act’s
    scienter requirement is “rigorous,” Universal Health 
    Servs., 136 S. Ct. at 2002
    , Swoben’s allegations satisfy it here.
    The defendants also suggest they could not have
    conducted their retrospective reviews in bad faith because
    retrospective reviews of a portion of an enrollee’s medical
    records are not a plausible means of identifying over-
    reporting errors. They point out that “CMS regulations deem
    a diagnosis code proper if it is supported by a single medical
    record by a single provider.” Joint Answering Br. 36.
    “Accordingly, the absence of documentation for a diagnosis
    code in a single retrospective review of a single provider’s
    charts does not establish that the submission of that code to
    CMS was improper: the code may simply be located in charts
    SWOBEN V. UNITED HEALTHCARE                             29
    not encompassed by the retrospective review.” 
    Id. We are
    not persuaded. First, if the retrospective reviews were
    designed in bad faith, then it is no defense that the reviews, as
    designed, could not readily identify over-reporting errors.
    Second, the record at this early stage does not tell us how
    easy or difficult it would have been for the defendants to
    identify over-reporting errors, and Swoben alleges only that
    the defendants intentionally prevented coders from doing so.
    Whether the defendants had a good-faith reason to design the
    reviews as they did is not a matter to decide at this stage of
    the proceedings, particularly where the defendants’ factual
    assertions are less than obvious. For instance, because CMS
    requires medical diagnosis codes to be supported by a
    medical record, it may be that each diagnosis code reported
    to CMS is linked to a specifically identified supporting
    medical record. In that event, if a reviewer finds a previously
    reported diagnosis code is not supported by the very medical
    record used to document the diagnosis code in the first place,
    then the diagnosis code was reported in error, even if it is
    possible that some other, unidentified record might support
    the same diagnosis.8 As the government points out, “[e]ven
    if it turns out that the diagnosis is supported by other medical
    records, the failure of [the] plan to investigate to make that
    determination – after it has been put on notice that the
    diagnosis may not be supported – makes its broad
    certification regarding the accuracy, completeness, and
    8
    In other words, if a Medicare Advantage organization relied on
    medical record X to justify submitting a particular diagnosis code to CMS
    initially, and the retrospective reviewer concludes X does not support that
    diagnosis, then the code should be withdrawn. If it turns out the code can
    be substantiated by a different medical record, then the code can be left in
    place or resubmitted. But the Medicare Advantage organization cannot
    simply ignore the reporting error because it speculates that some other
    medical record might support the same diagnosis code.
    30           SWOBEN V. UNITED HEALTHCARE
    truthfulness of submitted data false.” Br. United States as
    Amicus Curiae 17.
    The defendants also argue the statements by CMS in 2000
    regarding due diligence and good faith should not be given
    weight because, at the time, risk adjustment was based
    primarily on demographic factors rather than patient
    encounter data. Joint Resp. to Amicus Br. 9–10 & n.3. We
    disagree. First, the statements by CMS are authoritative not
    because of what they say about encounter data or diagnosis
    codes but because they provided clear guidance to Medicare
    Advantage organizations (then known as Medicare+Choice
    organizations) regarding their obligations under § 422.504(l)
    (then codified at § 422.502(l)), including their obligations
    under the “best knowledge, information, and belief” standard.
    Second, the defendants’ representations to the contrary
    notwithstanding, it is quite clear that the risk adjustment
    methodology in place in 2000 focused on patient encounter
    data, just as it does today. See 65 Fed. Reg. 40,246–51. The
    defendants point out that at the time CMS collected encounter
    data only for inpatient care. Joint Resp. to Amicus Br. at 9
    n.3. But, as CMS made clear at the time, it was already
    “developing a more comprehensive risk-adjustment
    methodology that uses diagnosis data from physician services
    and hospital outpatient department encounters” as well.
    65 Fed. Reg. at 40,247–48. Thus, when CMS emphasized the
    importance of due diligence and good faith in reporting
    patient encounter data in 2000, it clearly had within its
    contemplation the regime that was then in development and
    which was in place at the time the allegedly false claims were
    submitted in this case. Third, even if the defendants were
    correct that the focus of the risk adjustment methodology in
    2000 was on demographic factors rather than encounter data,
    SWOBEN V. UNITED HEALTHCARE                             31
    there is no question that CMS’ statements about due diligence
    and good faith were focused on the latter:
    M+C organizations have an obligation to take
    steps to ensure the accuracy, completeness,
    and truthfulness of the encounter data. We
    acknowledge that encounter data come into
    M+C organizations in great volume and from
    a number of sources, presenting significant
    verification challenges for the organizations.
    However, we believe that M+C organizations
    have an obligation to undertake “due
    diligence” to ensure the accuracy,
    completeness, and truthfulness of encounter
    data submitted to [CMS]. Therefore, they
    will be held to a “best knowledge,
    information, and belief” standard. Therefore,
    M+C organizations will be held responsible
    for making good faith efforts to certify the
    accuracy, completeness, and truthfulness of
    encounter data submitted.

    The statements CMS made in the preamble to the certification
    regulation merit deference. See, e.g., Christopher v. SmithKline Beecham
    Corp., 
    132 S. Ct. 2156
    , 2163 (2012); Fid. Fed. Sav. & Loan Ass’n v. de la
    Cuesta, 
    458 U.S. 141
    , 158 n.13 (1982) (“[W]e look to the preamble . . . for
    the administrative construction of the regulation, to which ‘deference is
    . . . clearly in order.’” (third alteration in original) (quoting Udall v.
    Tallman, 
    380 U.S. 1
    , 16 (1965))). CMS’ statements regarding the
    meaning of the “best knowledge, information, and belief” standard are
    entitled to deference because they represent the agency’s interpretation of
    its own regulation. The interpretation is also entitled to deference because
    it represents the agency’s considered judgment after notice and comment,
    32              SWOBEN V. UNITED HEALTHCARE
    The defendants also contend their certifications could not
    have been knowingly false because their conduct between
    2005 and 2012 represented at least an objectively reasonable
    interpretation of their obligations under § 422.504(l). Joint
    Suppl. Br. 12. See Safeco Ins. Co. of Am. v. Burr, 
    551 U.S. 47
    , 70 n.20 (2007) (“Where, as here, the statutory text and
    relevant court and agency guidance allow for more than one
    reasonable interpretation, it would defy history and current
    thinking to treat a defendant who merely adopts one such
    interpretation as a knowing or reckless violator.”); 
    Hagood, 929 F.2d at 1421
    (“To take advantage of a disputed legal
    question . . . is to be neither deliberately ignorant nor
    recklessly disregardful.”). We again disagree. CMS’ clear
    statements in the 2000 preamble – “[Medicare Advantage]
    organizations have an obligation to undertake ‘due diligence’
    to ensure the accuracy, completeness, and truthfulness of
    encounter data submitted to [CMS and] will be held
    responsible for making good faith efforts to certify the
    accuracy, completeness, and truthfulness of encounter data
    submitted,” 65 Fed. Reg. at 40,268 – resolved any ambiguity
    about the meaning of § 422.504(l). See Fid. Fed. Sav. &
    industry input and interagency consultation. See Establishment of the
    Medicare+Choice Program, 63 Fed. Reg. 34968, 35017 (June 26, 1998)
    (interim final rule with comment period); 65 Fed. Reg. at 40,176, 40,268,
    40,299 (final rule with comment period). Indeed, the good faith standard
    about which the defendants now complain appears to have been suggested
    by the industry. See 65 Fed. Reg. at 40,268, 40,299. Compare 63 Fed.
    Reg. at 35103 (interim rule), with 65 Fed. Reg. at 40,327–28 (final rule).
    We also afford deference to CMS’ interpretation of the regulation because
    it is consistent with the standard for liability under the False Claims Act,
    and therefore presumably carries out congressional intent. Cf. Wyeth v.
    Levine, 
    555 U.S. 555
    , 576–80 (2009) (declining to afford deference to
    statements in an agency’s preamble where the agency failed to offer
    interested parties notice or an opportunity for comment and the preamble
    was at odds with evidence of Congress’ purposes).
    SWOBEN V. UNITED HEALTHCARE                    33
    Loan 
    Ass’n, 458 U.S. at 158
    (“Any ambiguity in [the
    regulation’s] language is dispelled by the preamble
    accompanying and explaining the regulation.”).
    Consequently, ignoring the good faith and due diligence
    requirements would not have been objectively reasonable.
    The defendants also contend their § 422.504(l)
    certifications could not have been false because they offered
    only a qualified certification of their risk adjustment data,
    “based on best knowledge, information, and belief.” Joint
    Suppl. Br. 5–6. They rely on United States v. Ekelman &
    Associates, Inc., 
    532 F.2d 545
    , 550 (6th Cir. 1976) (“In
    certifying the truth of the information in the application ‘to
    the best of its knowledge and belief’ Franklin did no more
    than assert that it had no knowledge of, nor intention to make,
    misrepresentations.”). Ekelman is distinguishable on a
    number of grounds. First, § 422.504(l)’s “best knowledge,
    information, and belief” standard is informed by the 2000
    preamble, which makes clear the standard encompasses due
    diligence, good faith, reckless disregard and deliberate
    ignorance. See 65 Fed. Reg. at 40,268. In this sense,
    § 422.504(l)’s “best knowledge, information, and belief”
    standard is similar to the “best of the person’s knowledge,
    information, and belief” standard under Federal Rule of Civil
    Procedure 11, under which an attorney’s “signature certifies
    to the court that the signer has read the document, has
    conducted a reasonable inquiry into the facts and the law and
    is satisfied that the document is well grounded in both, and is
    acting without any improper motive.” Bus. Guides, Inc. v.
    Chromatic Commc’ns Enters., Inc., 
    498 U.S. 533
    , 542 (1991).
    Second, in contrast to Ekelman, this is not a case in which it
    is clear the defendants lacked any “intention to make[]
    misrepresentations.” 
    Ekelman, 532 F.2d at 550
    . Swoben’s
    allegations support the inference that the defendants certified
    34           SWOBEN V. UNITED HEALTHCARE
    that they believed the risk adjustment data were complete and
    accurate even though they did not believe that to be the case.
    Third, Ekelman was decided in 1976, a decade before
    Congress amended the False Claims Act to include a
    deliberate ignorance standard.           See False Claims
    Amendments Act of 1986, Pub. L. No. 99-562, § 2, 100 Stat.
    3153 (1986) (codified as amended at 31 U.S.C. § 3729(b)(1)).
    The deliberate ignorance standard does not allow a contractor
    to deliberately turn a blind eye to reporting errors and then
    attest that, to its knowledge, they do not exist.
    Finally, notwithstanding the certification and compliance
    regulations discussed in this opinion, the defendants invoke
    a separate regulation, 42 C.F.R. § 422.310(d), to argue they
    reasonably believed they were not required to take any
    affirmative steps to find unsupported diagnosis codes. Joint
    Suppl. Br. 6–7. In relevant part, § 422.310(d) states that
    Medicare Advantage “organizations must submit data that
    conform to CMS’ requirements for data equivalent to
    Medicare fee-for-service data, when appropriate, and to all
    relevant national standards.” 42 C.F.R. § 422.310(d).
    According to the defendants, because CMS does not verify
    diagnosis codes submitted to it by third-party medical
    providers under the Medicare fee-for-service program, this
    provision means Medicare Advantage organizations were not
    required to verify diagnosis codes either. We reject the
    defendants’ contention, again for multiple reasons. First,
    because nothing in § 422.310(d) speaks to a Medicare
    Advantage organization’s obligations to ensure the
    accuracy of risk adjustment data, it does not modify a
    Medicare Advantage organization’s obligations under
    §§ 422.503(b)(4)(vi) and 422.504(l). Second, this is not a
    case about whether Medicare Advantage organizations have
    to take affirmative steps to verify risk adjustment data. The
    SWOBEN V. UNITED HEALTHCARE                   35
    defendants indisputably took such steps by conducting
    retrospective reviews. This is a case about whether such
    organizations, having adopted affirmative verification
    procedures, have to conduct them in good faith.
    In sum, we conclude Swoben’s proposed fourth amended
    complaint adequately pleads a cognizable legal theory.
    B. The Proposed Fourth Amended Complaint Alleges
    Sufficient Factual Matter to Satisfy Rules 8, 9(b)
    and 12(b)(6) or May Be Amended to Do So
    The parties also dispute whether Swoben’s proposed
    fourth amended complaint satisfies Rule 8 and 9(b).
    1. Under Rule 8, we assume the veracity of a complaint’s
    factual allegations and then determine whether they plausibly
    give rise to an entitlement to relief. See Corinthian 
    Colls., 655 F.3d at 991
    . “A claim has facial plausibility when the
    plaintiff pleads factual content that allows the court to draw
    the reasonable inference that the defendant is liable for the
    misconduct alleged.” 
    Id. (quoting Ashcroft
    v. Iqbal, 
    556 U.S. 662
    , 678 (2009)).
    Claims under the False Claims Act are also subject to
    Rule 9(b). See 
    id. at 992;
    Cafasso, U.S. ex rel. v. Gen.
    Dynamics C4 Sys., Inc., 
    637 F.3d 1047
    , 1054 (9th Cir. 2011);
    
    Bly-Magee, 236 F.3d at 1018
    . Under Rule 9(b), a plaintiff
    “must state with particularity the circumstances constituting
    fraud.” Fed. R. Civ. P. 9(b). This means the plaintiff must
    allege “the who, what, when, where, and how of the
    misconduct charged,” Ebeid ex rel. United States v. Lungwitz,
    
    616 F.3d 993
    , 998 (9th Cir. 2010) (quoting Vess v. Ciba-
    Geigy Corp. USA, 
    317 F.3d 1097
    , 1106 (9th Cir. 2003)),
    36           SWOBEN V. UNITED HEALTHCARE
    including what is false or misleading about a statement, and
    why it is false, see 
    id. Knowledge, however,
    may be pled
    generally. See Corinthian 
    Colls., 655 F.3d at 996
    .
    Under our case law, Rule 9(b) serves two principal
    purposes. First, “allegations of fraud must be ‘specific
    enough to give defendants notice of the particular misconduct
    which is alleged to constitute the fraud charged so that they
    can defend against the charge and not just deny that they have
    done anything wrong.’” 
    Bly-Magee, 236 F.3d at 1019
    (quoting Neubronner v. Milken, 
    6 F.3d 666
    , 672 (9th Cir.
    1993)). Thus, “[p]erhaps the most basic consideration for a
    federal court in making a judgment as to the sufficiency of a
    pleading for purposes of Rule 9(b) . . . is the determination of
    how much detail is necessary to give adequate notice to an
    adverse party and enable that party to prepare a responsive
    pleading.” 5A Charles Alan Wright & Arthur R. Miller,
    Federal Practice and Procedure § 1298 (3d ed. 2016).
    Second, the rule serves “to deter the filing of complaints
    as a pretext for the discovery of unknown wrongs, to protect
    defendants from the harm that comes from being subject to
    fraud charges, and to prohibit plaintiffs from unilaterally
    imposing upon the court, the parties and society enormous
    social and economic costs absent some factual basis.” Bly-
    
    Magee, 236 F.3d at 1018
    (alteration omitted) (quoting In re
    Stac Elec. Sec. Litig., 
    89 F.3d 1399
    , 1405 (9th Cir. 1996)).
    By requiring some factual basis for the claims, the rule
    protects against false or unsubstantiated charges. See 
    id. (citing Rolo
    v. City Investing Co. Liquidating Trust, 
    155 F.3d 644
    , 658 (3d Cir. 1998)).
    Consistent with these requirements, “mere conclusory
    allegations of fraud are insufficient.” Wool v. Tandem
    SWOBEN V. UNITED HEALTHCARE                           37
    Computers Inc., 
    818 F.2d 1433
    , 1439 (9th Cir. 1987),
    overruled on other grounds as stated in Flood v. Miller, 35 F.
    App’x 701, 703 n.3 (9th Cir. 2002). Broad allegations that
    include no particularized supporting detail do not suffice, see
    
    Bly-Magee, 236 F.3d at 1018
    , but “statements of the time,
    place and nature of the alleged fraudulent activities are
    sufficient,” 
    Wool, 818 F.2d at 1439
    . Because this standard
    “does not require absolute particularity or a recital of the
    evidence,” Wright & Miller, supra, § 1298, a complaint need
    not allege “a precise time frame,” “describe in detail a single
    specific transaction” or identify the “precise method” used to
    carry out the fraud, Cooper v. Pickett, 
    137 F.3d 616
    , 627 (9th
    Cir. 1997). The complaint also need not “identify
    representative examples of false claims to support every
    allegation.” 
    Ebeid, 616 F.3d at 998
    . “[I]t is sufficient to
    allege ‘particular details of a scheme to submit false claims
    paired with reliable indicia that lead to a strong inference that
    claims were actually submitted.’” 
    Id. at 998–99
    (quoting
    United States ex rel. Grubbs v. Ravikumar Kanneganti,
    
    565 F.3d 180
    , 190 (5th Cir. 2009)).10
    Here, the proposed fourth amended complaint satisfies
    Rule 9(b) with respect to some defendants but not others.
    With respect to defendants United Healthcare and HealthCare
    Partners, the complaint offers more than broad allegations
    lacking supporting detail and provides a strong factual basis
    for Swoben’s claims. For instance, concerning United
    10
    Although many courts require less particularity “when some matters
    are beyond the knowledge of the pleader and can only be developed
    through discovery,” Wright & Miller, supra, § 1298, we declined to apply
    that principle to claims under the False Claims Act in 
    Ebeid, 616 F.3d at 999
    .
    38          SWOBEN V. UNITED HEALTHCARE
    Healthcare, operating as Secure Horizons, the complaint
    alleges:
    Between and during about 2005 and about
    2007, Secure Horizons used software, such as
    Plan Data Management, to create lists of
    patients whose medical charts were to be
    reviewed. These lists showed the patients that
    were susceptible of having . . . diagnoses that
    had not been previously reported, and
    identified the . . . diagnosis codes that were
    believed to be unreported. Secure Horizons
    provided these lists to its contracted medical
    groups and [independent physician
    associations (IPAs)], including but not limited
    to HealthCare Partners, who in turn had the
    lists used by coders to review the charts of the
    listed patients to determine whether the
    reviewed charts supported the . . . diagnosis
    codes identified on the lists. Such medical
    groups and IPAs, including but not limited to
    HealthCare Partners, reported to Secure
    Horizons the . . . diagnosis codes that were
    supported by properly documented medical
    charts that were reviewed, but made no
    attempt to determine or report those
    previously reported diagnosis codes that were
    unsupported by properly documented medical
    charts that were reviewed. HealthCare
    Partners did so with the knowledge and intent
    that the coders’ reviews would only increase,
    and not decrease, the number of diagnoses,
    and the respective risk scores in order to
    increase capitated payments paid by the
    SWOBEN V. UNITED HEALTHCARE                  39
    Government to Secure Horizons, of which
    HealthCare Partners received a portion.
    Fourth Am. Compl. ¶ 14. These allegations, in the context of
    the complaint as a whole, adequately allege the who, what,
    when, where and how of the alleged fraud. The complaint
    further alleges:
    During or after June 2008, HealthCare
    Partners utilized software, HCC Manager, to
    evaluate claims data and retrospectively
    reviewed the medical charts of tens of
    thousands of HealthCare Partners’ patients
    with severe illnesses. HealthCare Partners did
    so, even though the manufacturer of HCC
    Manager advised HealthCare Partners that the
    software should not be used for retrospective
    reviews because such use would create
    Medicare compliance violations. HealthCare
    Partners used the data generated by HCC
    Manager for prospective care, as well as
    retrospective review, of its Medicare patients’
    medical charts for previous years’
    submissions.
    Fourth Am. Compl. ¶ 16. These allegations too include the
    level of particularity Rule 9(b) requires.
    With respect to defendants Aetna, WellPoint and Health
    Net, by contrast, the complaint offers only broad allegations
    lacking particularized supporting details. As a typical
    example, the complaint alleges that, “[b]eginning in or about
    2005 and at least once per year thereafter,” these “Defendant
    HMOs” “retained coding companies and/or purchased
    40           SWOBEN V. UNITED HEALTHCARE
    specialized software to perform retrospective reviews of the
    medical charts of tens of thousands of their patients with
    severe illnesses.” Fourth Am. Compl. ¶ 12.
    The coders conducted their review of the
    medical charts of tens of thousands of
    defendants’ patients, determined the diagnosis
    codes that were supported by proper
    documentation of the reviewed medical
    charts, and provided their results to the
    defendant HMOs. The coders’ reviews
    resulted in (a) diagnosis codes that were
    supported by proper documentation . . . that
    had been previously submitted to the
    Government, and (b) new diagnosis codes that
    were supported by proper documentation . . .
    that had not been previously submitted to the
    Government. However, a large number of the
    reviewed medical charts did not contain
    proper documentation supporting the
    previously submitted diagnosis codes.
    Fourth Am. Compl. ¶ 13. These allegations may be sufficient
    to “give defendants notice of the particular misconduct which
    is alleged to constitute the fraud charged so that they can
    defend against the charge,” but they are insufficient to show
    the allegations against these defendants have a “factual
    basis.” 
    Bly-Magee, 236 F.3d at 1018
    –19. The allegations
    describe some details of a generalized scheme, but they
    provide no details linking these defendants to the scheme.
    Such allegations are insufficient under Rule 9(b).
    There is a significant gap between Swoben’s relatively
    detailed allegations involving United Healthcare and
    SWOBEN V. UNITED HEALTHCARE                    41
    HealthCare Partners on the one hand and his comparatively
    conclusory allegations regarding Aetna, WellPoint and Health
    Net on the other. Swoben alleges, for example, that United
    Healthcare “paid its contracted medical groups and IPAs,
    including but not limited to HealthCare Partners, between $40
    and $45 for every medical chart reviewed by them in 2005.”
    Fourth Am. Compl. ¶ 12. He alleges Pam Leal, a United
    Healthcare employee, was involved in the development of
    the allegedly faulty template used to report diagnosis codes
    to CMS. Fourth Am. Compl. ¶ 22. With respect to Aetna,
    WellPoint and Health Net, by contrast, the complaint offers
    only general allegations, lacking in similar details. Although
    the complaint broadly alleges these defendants engaged in
    biased retrospective reviews designed to identify only under-
    reporting errors, the absence of any details regarding these
    particular defendants prevents us from concluding the claims
    are sufficiently substantial to satisfy Rule 9(b). We have
    consistently rejected False Claims Act claims based on
    similarly broad and conclusory allegations. See 
    Ebeid, 616 F.3d at 1000
    (holding the complaint’s “general
    allegations – lacking any details or facts setting out the who,
    what, when, where, and how of the [alleged fraud]” – were
    insufficient to satisfy Rule 9(b) (internal quotation marks
    omitted)); 
    Cafasso, 637 F.3d at 1057
    (holding the complaint
    failed to satisfy Rule 9(b) where the allegations were lacking
    in detail); United States ex rel. Lee v. SmithKline Beecham,
    Inc., 
    245 F.3d 1048
    , 1051 (9th Cir. 2001) (holding a “broad
    claim” with “no factual support” was insufficient to satisfy
    Rule 9(b)). Without these details, the complaint does not
    “supply reasonable indicia that false claims were actually
    submitted.” 
    Ebeid, 616 F.3d at 999
    .
    In sum, we hold the proposed fourth amended complaint
    satisfies Rule 9(b) with respect to United Healthcare and
    42           SWOBEN V. UNITED HEALTHCARE
    HealthCare Partners, but not with respect to Aetna, WellPoint
    and Health Net.
    2. Swoben, however, may be able to cure these
    deficiencies by further amendment. Dismissals under Rule
    9(b) are functionally equivalent to dismissals under Rule
    12(b)(6). See Swartz v. KPMG LLP, 
    476 F.3d 756
    , 765 (9th
    Cir. 2007). Leave to amend, therefore, should be granted
    unless the pleading “could not possibly be cured” by the
    allegation of other facts. 
    Bly-Magee, 236 F.3d at 1019
    . On
    the record before us, we cannot say Swoben would be unable
    to plead with particularity the details missing from the fourth
    amended complaint with respect to Aetna, WellPoint and
    Health Net. See, e.g., Corinthian 
    Colls., 655 F.3d at 995
    –96;
    
    SmithKline, 245 F.3d at 1054
    ; 
    Bly-Magee, 236 F.3d at 1019
    .
    We recognize Swoben has previously amended his
    pleadings three times. As a general rule, leave to amend may
    be denied when a plaintiff has demonstrated a “repeated
    failure to cure deficiencies by amendments previously
    allowed.” Eminence Capital, LLC v. Aspeon, Inc., 
    316 F.3d 1048
    , 1052 (9th Cir. 2003) (quoting Foman v. Davis,
    
    371 U.S. 178
    , 182 (1962)). This is not a case, however, in
    which Swoben “took ‘three bites at the apple’ by alleging and
    re-alleging the same theories in an attempt to cure pre-
    existing deficiencies.” 
    Id. at 1053.
    The defendants’ motions
    to dismiss were the first pleadings to attack the sufficiency of
    Swoben’s allegations, the current decisions by the district
    court and this court are the first to address the sufficiency of
    those allegations, and Swoben is seeking his first opportunity
    to cure those deficiencies. Swoben also alleges a novel legal
    claim, and this opinion substantially clarifies what allegations
    would be sufficient to assert such a claim. Swoben should be
    SWOBEN V. UNITED HEALTHCARE                             43
    afforded an additional opportunity to present an adequate
    pleading.
    3. The defendants’ remaining arguments regarding Rule
    9(b) are not persuasive.
    The defendants argue Swoben’s pleadings are insufficient
    because they “do not describe any specific instances of
    falsity, let alone any such instances with particularity by
    identifying the time, place, and manner of the alleged falsity,
    the person making the false representation, or what they
    obtained thereby.” Joint Answering Br. 35; see also 
    id. at 40–41.
    As noted, however, the plaintiff need not “identify
    representative examples of false claims to support every
    allegation.” 
    Ebeid, 616 F.3d at 998
    . “[I]t is sufficient to
    allege ‘particular details of a scheme to submit false claims
    paired with reliable indicia that lead to a strong inference that
    claims were actually submitted.’” 
    Id. at 998–99
    (quoting
    
    Grubbs, 565 F.3d at 190
    ). Swoben, therefore, need not
    identify specific false § 422.504(l) certifications.11
    The defendants also argue Swoben’s pleadings “fail[] to
    identify a single instance where previously submitted codes
    11
    The defendants’ argument in their petition for rehearing en banc that
    a plaintiff can satisfy Rule 9(b) only by alleging representative examples
    of false claims is undercut by the Supreme Court’s recent decision in
    United Health 
    Services, 136 S. Ct. at 1996
    , rebuffing a similar attempt to
    cabin False Claims Act liability through artificial limits. The Court
    rejected the contention that liability attaches only to express false
    certifications rather than implied false certifications, reasoning that what
    matters is the substance of the claim. Similarly, what matters here is
    whether the complaint adequately pleads the circumstances of fraud to
    satisfy the dual purposes of Rule 9(b), not whether the complaint employs
    a particular means of doing so.
    44            SWOBEN V. UNITED HEALTHCARE
    were inconsistent with those identified during the
    retrospective reviews, or to explain why any such
    inconsistencies would necessarily lead to false claims.” Joint
    Answering Br. 35. Under Swoben’s theory, however, the
    false claims are the allegedly false § 422.504(l) certifications,
    not the erroneously reported diagnosis codes. See 
    Hendow, 461 F.3d at 1171
    (explaining that it “is the false certification
    of compliance which creates liability when certification is a
    prerequisite to obtaining a government benefit”). Swoben
    need not identify specific diagnosis codes that should have
    been withdrawn.
    The defendants next fault the proposed fourth amended
    complaint for using (often, though not exclusively) collective
    allegations to refer to the defendants rather than
    differentiating among them. Joint Answering Br. 38. The
    defendants are correct that “Rule 9(b) does not allow a
    complaint to merely lump multiple defendants together but
    requires plaintiffs to differentiate their allegations when suing
    more than one defendant and inform each defendant
    separately of the allegations surrounding his alleged
    participation in the fraud.” Corinthian 
    Colls., 655 F.3d at 997
    –98 (quoting 
    Swartz, 476 F.3d at 764
    –65). A plaintiff
    must “identify the role of each defendant in the alleged
    fraudulent scheme.” 
    Id. (quoting Swartz,
    476 F.3d at 765).
    There is no flaw in a pleading, however, where collective
    allegations are used to describe the actions of multiple
    defendants who are alleged to have engaged in precisely the
    same conduct. The flaw in Swoben’s allegations is not the
    use of collective allegations, but the failure to allege
    particular details of the scheme as applied to defendants
    Aetna, WellPoint and Health Net.
    SWOBEN V. UNITED HEALTHCARE                   45
    Finally, the defendants argue with respect to the RADV
    audits that “Swoben fails to provide any of the particular
    details required by Rule 9(b), . . . which would be necessary
    for these allegations to have any relevance to the Defendants’
    knowledge or intent.” Joint Answering Br. 42. As noted,
    however, knowledge need not be pled with particularity. See
    Fed. R. Civ. P. 9(b); Odom v. Microsoft Corp., 
    486 F.3d 541
    ,
    554 (9th Cir. 2007). The defendants’ argument therefore falls
    short.
    In sum, we hold Swoben’s pleadings either satisfy Rules
    8, 9(b) and 12(b)(6) or might be able to do so through further
    amendment. Because the complaint also alleges a cognizable
    legal theory, amendment would not be futile. The district
    court abused its discretion by denying leave to amend on this
    ground.
    II. The District Court Abused its Discretion By Denying
    Leave to Amend Based on Undue Delay
    The district court alternatively denied leave to amend
    “based on undue delay” because “Swoben was aware of the
    purportedly ‘new’ allegations he proposes to add to the
    Fourth Amended Complaint since at least 2005.”
    We conclude the district court abused its discretion by
    relying on undue delay. Undue delay by itself is insufficient
    to justify denying leave to amend, see Owens v. Kaiser
    Found. Health Plan, Inc., 
    244 F.3d 708
    , 712–13 (9th Cir.
    2001), and the record here does not support any additional
    ground – such as prejudice or bad faith, see Johnson v.
    Mammoth Recreations, Inc., 
    975 F.2d 604
    , 607 (9th Cir.
    1992) – that would justify the denial of leave to amend in
    combination with undue delay.
    46            SWOBEN V. UNITED HEALTHCARE
    The defendants’ argument they would be prejudiced by
    affording Swoben leave to amend is unpersuasive. They fault
    Swoben for failing to announce his intention to seek leave to
    amend during the meet-and-confer conferences preceding the
    filing of their motions to dismiss. See C.D. Cal. R. 7-3. They
    argue that, if Swoben had announced his intention to seek
    amendment at that time, they could have avoided the expense
    of preparing their motions to dismiss. In the absence of bad
    faith, however, litigation expenses incurred before a motion
    to amend is filed do not establish prejudice. See 
    Owens, 244 F.3d at 712
    . More broadly, the defendants have not
    shown prejudice here. The litigation against these defendants
    is at a very early stage, Swoben does not seek to assert a new
    legal theory and this is Swoben’s first attempt to cure
    deficiencies in his complaint. The circumstances of this case
    stand in stark contrast to those in the cases on which the
    defendants rely. See AmerisourceBergen Corp. v. Dialysist
    W., Inc., 
    465 F.3d 946
    , 953–54 (9th Cir. 2006) (the plaintiff
    sought leave to amend a reply to a counterclaim to assert a
    new legal theory, which “would have unfairly imposed
    potentially high, additional litigation costs . . . that could have
    easily been avoided”); Ascon Props., Inc. v. Mobil Oil Co.,
    
    866 F.2d 1149
    , 1160–61 (9th Cir. 1989) (the defendant had
    filed several motions to dismiss over several years of active
    litigation, the plaintiff had been given several opportunities
    to cure the deficiencies in the complaint, the plaintiff had
    prosecuted the action in a dilatory fashion and the plaintiff
    sought to amend the complaint to assert a new legal theory).
    CONCLUSION
    The district court abused its discretion by dismissing
    Swoben’s third amended complaint without leave to amend
    based on futility of amendment and undue delay. The
    SWOBEN V. UNITED HEALTHCARE              47
    judgment is vacated and the case is remanded for further
    proceedings.
    VACATED AND REMANDED. Costs on appeal are
    awarded to Swoben.
