    SHELTON BARNES; MICHAEL JONES; HENRY EVANS; PAULA JONES;
    GREGORY MOLDEN, M.D.,
    Defendants–Appellants.
    Appeal from the United States District Court
    for the Eastern District of Louisiana
    Before OWEN, Chief Judge, and HAYNES and COSTA, Circuit Judges.
    PRISCILLA R. OWEN, Chief Judge:
    Shelton Barnes, Michael Jones, Henry Evans, Paula Jones, and Gregory
    Molden were convicted of offenses related to Medicare fraud. We affirm.
    I
    Dr. Shelton Barnes, Dr. Michael Jones, Dr. Henry Evans, Paula Jones,
    and Dr. Gregory Molden were each previously employed by Abide Home Care
    Services, Inc., a home health agency owned by Lisa Crinel. Barnes, Michael
    Jones, Evans, and Molden served as “house doctors.”           In that role, the
    physicians referred patients to Abide for home health care services. Paula
    Jones, Michael Jones’s wife, was one of Abide’s billers. As a biller, Jones would
    process Medicare filings. She would use the Kinnser billing system (Kinnser)
    Case: 18-31074       Document: 00515618613         Page: 2     Date Filed: 10/28/2020
    No. 18-31074
    to ensure that all appropriate documentation existed for each bill. As part of
    Abide’s business model, it would “provide home health services to qualified
    patients and then bill Medicare accordingly.”
    Medicare reimburses providers for home health care services if a
    particular patient is (1) eligible for Medicare and (2) meets certain
    requirements.     Those requirements include, inter alia, that the patient is
    “‘homebound,’ under a certifying doctor’s care, and in need of skilled services.” 1
    Certifying a patient for home health care begins with an initial referral, which
    typically originates with the patient’s primary care physician. 2 Next, “a nurse
    goes to the patient’s home to assess if [he or] she is homebound, completing an
    Outcome and Assessment Information Set [(OASIS)].” 3                  From the OASIS
    assessment, the nurse develops a plan of care on a form known as a “485” for
    the prescribing physician’s review. Only a physician can approve a 485 plan.
    Physicians are expected to review the forms to ensure they are accurate. These
    forms, as well as a face-to-face addendum certifying that the nurse met with
    the patient, are then routed to Medicare. 4 This process permits payment for
    one 60-day episode. Patients can then be recertified for subsequent episodes.
    Medicare determines how much will be paid for each episode based, in
    part, on the patient’s diagnosis. Each diagnosis has a corresponding code
    derived from the International Statistical Classification of Diseases and
    Related Health Problems 9th Revision (an ICD-9 code). Reimbursements are
    higher for some diagnoses than others. So-called “case-mix diagnoses” such as
    rheumatoid arthritis, cerebral lipidosis, and low vision, receive higher
    payments than other, comparatively simpler diagnoses. As a result, false or

    erroneous entries on the OASIS form can ultimately result in higher Medicare
    reimbursements.
    The government came to suspect that Abide was committing health care
    fraud. Specifically, the government alleged that “Abide billed Medicare based
    on plans of care that doctors authorized for medically unnecessary home health
    services.” According to the government, several patients who had received
    home health care from Abide did not, in fact, need such services.          Each
    physician had “approved [case-mix] diagnoses to patients on . . . 485s that were
    medically unsupported.” Paula Jones had also participated in the scheme.
    Through Kinnser, Abide employees were able to predict how much Medicare
    would reimburse for a particular episode of home health care. If the episode
    did not meet Abide’s “break-even point,” Jones would send “the files back to
    the case managers to see if they could get the score up.” These and other
    actions “fraudulently inflated Medicare’s reimbursement to Abide.”
    Relatedly, the government also came to suspect that Abide was “pay[ing]
    doctors, directly or indirectly, for referring patients.” The government alleged
    that Crinel (the owner of Abide) had paid the physicians for patient referrals.
    Some of these payments were “disguised as compensation for services
    performed as [medical directors]” for Abide. The government also alleged that
    Paula Jones’s salary, which had doubled during her time working for Abide,
    was based on her husband’s referrals. This conduct, the government alleged,
    constituted a violation of 42 U.S.C. §§ 1320a-7b(b)(1), (b)(2)—the anti-kickback
    statute.
    Barnes, Michael Jones, Evans, Paula Jones, and Molden were each
    charged with conspiracy to commit health care fraud and conspiracy to violate
    the anti-kickback statute.   Each physician was also charged with several
    counts of substantive health care fraud. Finally, Barnes was charged with
    obstructing a federal audit in violation of 
    18 U.S.C. §§ 2
     and 1516. According
    3

    No. 18-31074
    to the government, upon learning he was under audit, Barnes falsified
    documents to justify his fraudulent certifications.
    At trial, Crinel, Wilneisha Jakes (Crinel’s daughter and an Abide
    employee), Rhonda Maberry (an assistant manager at Abide), and Eleshia
    Williams (Barnes’s biller) testified for the government. Dr. Lutz also testified
    for the government. He evaluated the medical records of several of Abide’s
    patients and opined as to whether home health care was medically necessary.
    The defendants presented several witnesses; Evans also testified in his own
    defense. The jury convicted Barnes, Michael Jones, Paula Jones, and Molden
    of conspiracy to commit health care fraud and conspiracy to violate the anti-
    kickback statute. Barnes, Evans, Michael Jones, and Molden were each found
    guilty of several counts of substantive health care fraud.                 The jury also
    convicted Barnes of obstructing a federal audit.                 Thereafter, each was
    sentenced to a term of imprisonment. This appeal followed.

    We first consider the issues raised by Shelton Barnes.
    A
    Barnes challenges the sufficiency of the evidence supporting each of his
    convictions. “[P]reserved sufficiency-of-the-evidence challenges” are reviewed
    de novo. 5 Under that standard, “we review[ ] the record to determine whether,
    considering the evidence and all reasonable inferences in the light most
    favorable to the prosecution, any rational trier of fact could have found the
    essential elements of the crime beyond a reasonable doubt.” 6

    Barnes was convicted on both counts of conspiracy identified in the
    indictment. Count 1 alleged that he conspired to commit healthcare fraud, in
    violation of 
    18 U.S.C. §§ 1347
     and 1349. Section 1347 punishes “[w]hoever
    knowingly and willfully executes, or attempts to execute, a scheme or
    artifice . . . to defraud any health care benefit program . . . in connection with
    the delivery of or payment for health care benefits, items, or services.” 7 To
    convict on Count 1, the government was required to prove: “(1) two or more
    persons made an agreement to commit health care fraud; (2) the defendant
    knew the unlawful purpose of the agreement; and (3) the defendant joined in
    the agreement willfully, that is, with the intent to further the unlawful
    purpose.” 8
    Count 2 alleged that Barnes conspired with others to “knowingly and
    willfully solicit and receive . . . kickbacks and bribes . . . in return for referring
    individuals for” Medicare services in violation of 42 U.S.C. §§ 1320a-7b(b)(1),
    (b)(2), and 
    18 U.S.C. § 371
    . As summarized in United States v. Gibson, the
    anti-kickback statute “criminalizes the payment of any funds or benefits
    designed to encourage an individual to refer another party to a Medicare
    provider for services to be paid for by the Medicare program.” 9 To convict on
    Count 2, the government was required to establish: “(1) an agreement between
    two or more persons to pursue [the] unlawful objective; (2) the defendant’s
    knowledge of the unlawful objective and voluntary agreement to join the
    inconsistent with every conclusion except that of guilt,’ in order to be sufficient.” (quoting
    United States v. Moreno,

    conspiracy; and (3) an overt act by one or more of the members of the
    conspiracy in furtherance of the objective of the conspiracy.” 10
    The sine qua non of a conspiracy is an agreement. 11 We have previously
    recognized that “[a]greements need not be spoken or formal.” 12                         “[T]he
    [g]overnment can use evidence of the conspirators’ concerted actions to prove
    an agreement existed.” 13 Nevertheless, “[p]roof of an agreement to enter a
    conspiracy is not to be lightly inferred.” 14 “‘Mere similarity of conduct among
    various persons and the fact that they have associated with or are related to
    each other’ is insufficient to prove an agreement.” 15 “Conspirators do not enter
    into an agreement by happenstance . . . .” 16
    On appeal, Barnes relies heavily on our previous decision in United
    States v. Ganji in arguing that there was insufficient evidence to convict him
    of either conspiracy. In Ganji, Elaine Davis, the owner of a home health care
    agency, and Dr. Ganji, a physician associated with Davis’s agency, were
    charged and ultimately convicted of conspiracy to commit health care fraud
    and substantive health care fraud. 17              We reversed on sufficiency-of-the-
    evidence grounds. 18        As to each conspiracy conviction, we concluded the
    government failed to establish either individual entered into an agreement to
    commit health care fraud. 19 Unlike “the vast majority of concert of action
    cases,” the government did not produce an “insider” who could testify as to

    either Dr. Ganji’s or Davis’s involvement in the alleged conspiracy. 20
    Moreover, “[t]he quality and probative strength of the [g]overnment’s
    ‘concerted action’ evidence in [Ganji fell] well short of the [requisite]
    threshold.” 21 As to the substantive health care fraud convictions, we concluded
    “there [was] insufficient evidence to show that [either individual] knowingly
    executed a scheme to defraud Medicare.” 22 According to Barnes, “[t]he facts
    described [in Ganji] are practically identical, or more than substantially so, to
    the facts brought out at trial.” We disagree.
    As to Count 1, Maberry testified to signing Barnes’s name on 485s, and
    to certifying falsely that patients were under Barnes’s care. The jury heard
    evidence that Barnes was aware of this conduct. Moreover, Crinel testified
    that Barnes was paid for patient referrals, which established a potential
    motive for Barnes’s conduct. Importantly, Crinel had also pleaded guilty to
    conspiring with Barnes to commit health care fraud. Finally, the government
    presented statistical evidence reflecting that Barnes billed for case-mix
    diagnoses with significantly greater frequency than other providers in
    Louisiana and the country as a whole. As the district court noted, the numbers
    are significantly different such that they are “too large to have happened by
    chance.” Collectively, this evidence more than sufficiently establishes the
    elements of conspiracy.
    Regarding Count 2, Wilneisha Jakes’s and Crinel’s testimony provide
    sufficient evidence of a conspiracy to violate the anti-kickback statute. During
    Jakes’s testimony, she admitted that: (1) Barnes was paid for patient referrals;
    (2) his employment agreement was created merely to establish a paper trail;
    and (3) she entered into an agreement with Barnes to pay him for his referrals.

    No. 18-31074
    Likewise, Crinel testified that Barnes was being paid for patient referrals. As
    with Count 1, because she pleaded guilty to conspiring with Barnes to violate
    the anti-kickback statute, her testimony regarding Barnes’s role in the
    conspiracy was especially probative.
    Of course, Barnes’s case bears some similarities to Ganji.             But we
    strongly disagree with his assessment that his case is “practically identical, or
    more than substantially so,” to Ganji. Perhaps the most significant difference
    is the fact that this case is one of “the vast majority of concert of action cases[]
    [in which] the [g]overnment presents an insider with direct evidence of the
    conspiratorial scheme.” 23
    2
    Counts 3 through 17 each alleged a separate violation of 
    18 U.S.C. § 1347
    . Counts 3 through 7 concerned patient HaHa; Counts 8 through 10
    concerned patient KiSt; and Counts 11 through 17 concerned patient ArGi.
    Barnes again relies on Ganji, and specifically this court’s recognition
    that to convict a physician of violating 
    18 U.S.C. § 1347
     the prosecution “must
    provide evidence that the accused doctor executed a fraudulent scheme with
    knowledge that the patient was not homebound.” 24 According to Barnes, his
    convictions should be overturned because the government did not produce one
    scintilla of evidence that Barnes “knew [HaHa, KiSt, or ArGi were] not
    homebound.” 25
    Despite Barnes’s contentions, the government presented sufficient
    evidence that Barnes knew these patients were not home-health-care eligible.
    Maberry, Barnes’s nurse practitioner, told him that not all of the patients he
    certified as homebound were, in fact, homebound. Moreover, the substantial

    No. 18-31074
    evidence presented as to Counts 1 and 2 undermines Barnes’s argument.
    Evidence of a financial incentive for home health care referrals and statistical
    evidence probative of fraudulent conduct are circumstantial evidence of
    Barnes’s knowledge.
    Specific evidence relating to each patient reinforces this conclusion. As
    to patient HaHa, Maberry testified that HaHa’s billings lacked appropriate
    supporting documentation. Dr. Lutz testified that HaHa did not know Barnes
    and that several of HaHa’s diagnosis codes were “shuffled” during
    recertifications. As to patient KiSt, Barnes lacked records for this patient, and
    he never met with her. Maberry, who pleaded guilty to conspiring with Barnes
    to commit Medicare fraud regarding KiSt’s home health certification, testified
    that 485s had been pre-signed before visiting KiSt. Lastly, as to patient ArGi,
    Dr. Lutz testified that Barnes’s patient files for ArGi lacked the documentation
    that should have existed if ArGi had the conditions Barnes alleged ArGi had.
    Also, Maberry signed Barnes’s signature on several of the relevant 485s
    identified in the indictment. In the aggregate, this evidence is more than
    sufficient for a reasonable juror to conclude that Barnes’s conduct was
    fraudulent.
    3
    We next consider Barnes’s conviction for obstructing a federal audit in
    violation of 
    18 U.S.C. §§ 2
     and 1516. Section 1516 provides the following:
    Whoever, with intent to deceive or defraud the United States,
    endeavors to influence, obstruct, or impede a Federal auditor in
    the performance of official duties relating to a person, entity, or
    program receiving in excess of $100,000, directly or indirectly,
    from the United States in any 1 year period under a contract or
    subcontract, grant, or cooperative agreement, . . . shall be fined
    under this title, or imprisoned not more than 5 years, or both. 26
    26   
    18 U.S.C. § 1516
    (a).
    9
    Case: 18-31074       Document: 00515618613         Page: 10     Date Filed: 10/28/2020
    No. 18-31074
    On appeal, Barnes raises two arguments as to why his conviction as to Count
    47 should be reversed.
    Barnes’s first argument concerns § 1516’s jurisdictional element, which
    specifically requires that the conduct in question be directed at “a Federal
    auditor in the performance of official duties relating to a person, entity, or
    program receiving in excess of $100,000, directly or indirectly, from the United
    States in any 1 year period.” 27         Under his proposed interpretation of the
    statute, § 1516 can only apply if he received “in excess of $100,000 . . . from the
    United States in any 1 year period.” 28 Thus, because no such evidence was
    adduced at trial, he is entitled to an acquittal. The government disagrees and
    instead argues Barnes’s conviction should be affirmed because Medicare
    received in excess of $100,000 from the United States.
    Reviewing this question of statutory interpretation de novo, we are
    inclined to side with the government. 29 Under a plain-text reading of the
    statute, it is telling that an individual violates § 1516 when he or she
    “endeavors to influence, obstruct, or impede a Federal auditor in the
    performance of official duties relating to a person, entity, or program receiving
    in excess of $100,000 . . . from the United States.” 30 In this case, the audit was
    undoubtedly related to Medicare, a “program receiving in excess of
    $100,000 . . . from the United States.” 31 Further, we are not convinced that
    Barnes’s alternative interpretation represents a better reading of the statute.
    Under his interpretation, the amount of money received by an alleged violator
    would often be the statute’s limiting criterion. Such a result would inherently

    thwart Congress’s intentions when it comes to enforcing the statute.                We
    therefore decline to adopt Barnes’s proposed reading of § 1516’s jurisdictional
    element.     Because there was sufficient evidence to establish § 1516’s
    jurisdictional element under the interpretation we adopt today, we reject
    Barnes’s first argument concerning Count 47.
    Next, Barnes contends there was insufficient evidence he engaged in
    obstructive conduct. But the jury heard evidence that Barnes received several
    letters from Medicare indicating that he would not be paid for certain Medicare
    billings   because the billings       lacked the      appropriate documentation.
    Thereafter, he gave over fifty audit letters to Maberry, his nurse practitioner.
    He then informed her that they had “received the audit, and in order for him
    to get paid[, they] had to complete that audit for Medicare.” In response,
    Maberry and Eleshia Williams, Barnes’s biller, completed paperwork in order
    to justify these billings. Some documents were falsified to do so. Both Maberry
    and Williams testified that Barnes was aware of these actions. According to
    Maberry, Barnes had implied that they should take such actions. Moreover,
    she testified that she falsified, and Barnes signed, care plan log sheets in
    response to the audit. Williams noted that Barnes had observed and tacitly
    approved of Maberry signing his name on medical documentation as part of
    the audit.
    We agree with the government that logical and reasonable inferences
    from this evidence would enable a reasonable juror to conclude that Barnes
    acted “with intent to deceive or defraud the United States,” 32 as required by
    § 1516(a), or that he acted “with the intent to facilitate” the offense’s
    commission, as required by § 2. 33

    B
    Barnes asserts that the prosecutor made improper comments during
    closing arguments.      During those arguments, Paula Jones’s attorney
    challenged the credibility of Dr. Lutz, the government’s expert witness.
    Specifically, her attorney stated:
    Dr. Lutz may not be going where his grandfather was going. His
    grandfather may go to church, Dr. Lutz goes to Galatoire’s. There’s
    a big difference. When I listen to him, it was almost like an
    aristocratic arrogance of saying, okay, we have all these problems
    in New Orleans, but I’m going to be at Galatoire’s and I’m going to
    write out a big prescription -- Weight Watchers for everybody.
    That’s going to solve all our problems, as he takes another sip of
    his martini. That’s an aristocratic arrogance. Never seen the
    patients, never go down to the areas of the city that need it.
    The reference to Galatoire’s, a restaurant in the French Quarter, stemmed
    from Dr. Lutz’s testimony during trial that he does not eat at Galatoire’s on
    Fridays during lunch because “[t]here’s too many attorneys” there.
    The government responded to the defense’s comments during their
    rebuttal argument. The prosecutor specifically stated:
    He is not an elitist. He worked for the City of New Orleans when
    these defendants, these elite defendants probably weren’t out of
    medical school. He worked for the City of New Orleans in home
    health for the inner city. So that’s offensive that this man can’t go
    out and have a martini at a place he said he did. Well, he won’t
    because these defense attorneys are there.
    The defense objected to the remarks at a bench conference, but the court did
    not take any action. The court did note during post-trial motions that such
    comments were “improper.” However, it went on to state that no action was
    necessary because “the jury was presented with abundant evidence of
    [Barnes’s] guilt” and the comments were but a small part of a long trial.
    On appeal, Barnes alleges the prosecutor’s comments were “offensive
    and inflammatory.” He argues the comments invoked class-stereotypes by
    12
    Case: 18-31074       Document: 00515618613        Page: 13     Date Filed: 10/28/2020

    referring to the defendants as elitist and impugned the integrity of defense
    counsel. According to him, the comments were “so wrong[] that speculation on
    whether it had an impact on the jury need not be suggested.” We agree the
    comments were improper but believe such comments did not affect Barnes’s
    substantial rights. We therefore decline his request for a new trial.
    We apply a two-step process when evaluating the propriety of a
    prosecutor’s comments during closing arguments. First, this court “initially
    decide[s] whether . . . the prosecutor made an improper remark.” 34 “Second,
    ‘[i]f an improper remark was made, we must then evaluate whether the remark
    affected the substantial rights of the defendant.’” 35 Courts consider “(1) the
    magnitude of the prejudicial effect of the prosecutor’s remark, (2) the efficacy
    of any cautionary instruction by the judge, and (3) the strength of the evidence
    supporting the conviction.” 36 De novo review applies to the first inquiry. 37 In
    contrast, “the question of whether . . . the defendant’s substantial rights were
    affected [is reviewed] under the abuse of discretion standard.” 38
    As to the first part of the analysis, the district court correctly held that
    the prosecutor’s comments were improper. The prosecutor’s description of the
    defendants as elitists was arguably in response to the defense’s initial attacks
    against Dr. Lutz.      But even assuming that comment was appropriate, no
    similar justification validates the prosecution’s comments aimed at defense
    counsel.    Attacking defense counsel was unwarranted, unprovoked, and

    irrelevant.       The district court therefore correctly concluded that the
    prosecution’s remarks during rebuttal were improper.
    Nevertheless, these comments did not affect Barnes’s substantial rights.
    Viewed in context, the comments were not overly prejudicial and were unlikely
    to inflame the passions of the jury. 39 Moreover, these comments were but a
    small part of a significant trial. Admittedly, the judge did not provide a specific
    curative instruction concerning the prosecutor’s comments.                    Yet the case
    against Barnes was strong.            As the district court aptly stated, “it strains
    credulity to argue that this offhand comment—a few seconds in a four-week
    trial—had a prejudicial impact on [Barnes’s] substantial rights.” We therefore
    decline Barnes’s request for a new trial as a result of the prosecutor’s improper
    comments during closing arguments.
    C
    Barnes challenges the district court’s refusal to admit patient consent
    forms into evidence. Dr. Lutz testified as an expert for the government that
    several patients treated by the physicians in this case “had no business being
    in home health.” During Dr. Lutz’s testimony, Barnes sought to introduce
    consent forms “signed by patients KiSt, HaHa[,] and ArGi in which those
    patients acknowledge they are homebound.” The district court refused to
    admit this evidence. It concluded that: (1) the forms constituted hearsay that
    was inadmissible under Rule 803(4) (medical records exception) or Rule 807
    (residual exception); (2) the forms were inadmissible “under Rules 703 or 705,
    as Dr. Lutz did not rely on the documents in forming his opinion, and did not
    use the documents as underlying facts or data;” and (3) the evidence was
    39   See United States v. Phea, 
    755 F.3d 255
    , 267-68 (5th Cir. 2014).

    No. 18-31074
    inadmissible even for impeachment purposes because the forms “were not prior
    inconsistent statements by Dr. Lutz.”
    On appeal, Barnes contends these documents were admissible hearsay
    and were admissible for the purposes of impeaching Dr. Lutz’s testimony. We
    review “evidentiary rulings for abuse of discretion.” 40 “A district court abuses
    its discretion when its ruling is based on an erroneous view of the law or a
    clearly erroneous assessment of the evidence.” 41 If the district court did abuse
    its discretion, any resulting error is “subject to harmless error review.” 42 “A
    reversal will not be warranted unless the defendant shows ‘that the district
    court’s ruling caused him substantial prejudice.’” 43 Applying this framework,
    the district court did not abuse its discretion when it refused to admit the
    consent forms into evidence.
    First, the forms were inadmissible as hearsay evidence. The evidence
    did not qualify for admission under Rule 803(4). That exception requires that
    the statements be “made for—and [are] reasonably pertinent to—medical
    diagnosis or treatment.” 44        Here, though, the statements (i.e., the forms)
    address criteria for home health care, not a specific medical diagnosis or
    treatment. The forms were also inadmissible under Rule 807 because they
    lacked indicia of reliability: 45 As the district court noted, “the nurses who
    signed the forms [or provided them to the patients for their signature] either
    pleaded guilty to health care fraud or were otherwise implicated in the fraud.”

    Second, the evidence was inadmissible under Rules 703 and 705 because
    Dr. Lutz did not rely on those forms in making his opinion. 46 Finally, the forms
    were inadmissible as prior inconsistent statements. As the district court noted,
    the patients made the statements (i.e., filled out and signed the forms), not Dr.
    Lutz. Because Dr. Lutz did not originally make the statements, they could not
    be used to impeach his credibility. 47
    Having addressed and rejected each of Barnes’s arguments as to why the
    patient consent forms were admissible, we express no further opinion as to
    whether the forms may have been admissible under any other legal theory. 48
    Accordingly, the district court did not abuse its discretion when it refused to
    admit the proffered consent forms into evidence.

    At trial, Barnes sought to have several Medicare regulations read to the
    jury as instructions. These regulations covered a variety of topics, including,
    inter alia, (1) a list of services available to patients eligible for home health
    care, (2) the certification requirements necessary for a patient to receive home
    health care, (3) permissible financial relationships between physicians and
    health care agencies, and (4) Medicare’s guidance concerning the frequency of
    face-to-face meetings between physicians and their home-health patients.
    The district court ultimately declined to read those instructions to the
    jury. It was “particularly concerned about committing error by instructing the
    46   See FED. R. EVID. 703, 705.
    47   See FED. R. EVID. 613(b) (“Extrinsic evidence of a witness’s prior inconsistent
    statement is admissible only if the witness is given an opportunity to explain or deny the
    statement and an adverse party is given an opportunity to examine the witness about it, or
    if justice so requires.” (emphasis added)).

    jury on the meaning of the Medicare regulations in a criminal trial,” relying
    heavily on this court’s decision in United States v. Christo. 49 In Christo, the
    prosecution presented “evidence and argument concerning violations of [a civil
    regulatory statute]” 50 during a criminal trial focusing on “misapplication of
    bank funds.” 51    We reversed the defendant’s convictions after noting the
    prejudicial effect of “bootstrap[ping] a series of . . . civil regulatory violation[s]”
    into a criminal trial. 52 “The trial court’s instructions and emphasis on [the civil
    regulatory statute],” we noted, “served only to compound the error by
    improperly focusing the jury’s attention to the prohibitions of [the civil
    regulatory statute].” 53 Concluding that Christo controlled, the trial judge here
    refused to read Barnes’s requested instructions. Importantly, though, the
    substance of those instructions was brought to the jury’s attention numerous
    times. The actual Medicare regulations upon which the proposed instructions
    were based “were admitted into evidence without objection and provided to the
    jury.” The judge also permitted defense counsel to argue the substance of these
    instructions during closing arguments.
    On appeal, Barnes asserts the district court erred when it refused to read
    the proffered instructions. According to him, “[j]ust having these complex
    regulations used and battered about during the trial, when they formed the
    heart and soul of the defense, was not adequate.” The judge, as a neutral and
    detached party, should have provided the jury with guidance on these
    regulations. Moreover, he argues the district court’s reliance on Christo was
    inappropriate.     Unlike in Christo, “the government [in this case was not]
    attempting to use regulations to sustain its burden of proof.”              Christo is

    distinguishable, Barnes asserts, because in this case the defense requested the
    instruction. Thus, in Barnes’s estimation, the district court’s refusal to provide
    the requested instructions constitutes error.
    There is no error in the district court’s refusal to read the proffered
    instructions to the jury.        “Whe[n], as here, the defense requested a jury
    instruction and the request was denied, we review the denial for abuse of
    discretion.” 54   “A district court abuses its discretion by failing to issue a
    defendant’s requested instruction if the instruction (1) is substantively correct;
    (2) is not substantially covered in the charge given to the jury; and (3) concerns
    an important point in the trial so that the failure to give it seriously impairs
    the defendant’s ability to present effectively a particular defense.” 55
    We assume without deciding that the proffered instructions were
    “substantively correct” and “not substantially covered in the charge given to
    the jury.” 56 Nevertheless, the refusal to read the instructions did not impair
    Barnes’s “ability to present effectively a particular defense.” 57 As the district
    court outlined, the jury was amply aware of the Medicare regulations and their
    importance to this case. The district court also properly relied on Christo. It
    is not difficult to imagine a jury confusing the standards articulated in the
    Medicare regulations with the appropriate legal standard in a criminal case.
    These risks are present irrespective of whether the government or the defense
    requests these types of instructions. We express no opinion whether it would
    have constituted an abuse of discretion if the judge had actually read the
    proffered instruction at the defense’s behest. But given the wide latitude

    Michael Jones contends there was insufficient evidence to convict him of
    conspiracy to commit health care fraud (Count 1), conspiracy to violate the
    anti-kickback statute (Count 2), and seven counts of substantive health care
    fraud (Counts 18 and 22 through 27). Count 18 alleged fraud concerning
    patient ArGi; Counts 22 through 26 concerned patient LiSc; and Count 27
    concerned patient EvLa.
    A
    Jones asserts many of the same arguments as his co-defendants and
    likewise relies heavily on Ganji. As to Count 1, the circumstantial evidence
    offered against Jones was sufficient to convict him of conspiracy to commit
    health care fraud. Like many of the other defendants, Jones had a financial
    incentive to refer patients to home health care. From this evidence, the jury
    could reasonably infer that Jones had a motive to falsify health care
    certifications. Statistical evidence reflected that Jones diagnosed patients
    with certain conditions significantly more often than other doctors. The jury
    also heard substantial evidence that Jones himself certified patients for home
    health care even when those patients were ineligible for such services. Finally,
    Crinel pleaded guilty to conspiring with Jones to commit health care fraud.
    Together, this evidence is far stronger than that presented in Ganji; it is more
    than enough to find Jones guilty of conspiracy to commit health care fraud.
    Similarly, the record contains ample evidence that Jones agreed to
    violate the anti-kickback statute. Crinel’s testimony alone suffices. According
    to Crinel, Jones told her that if she increased Paula Jones’s salary, “he would
    send patients to substantiate her salary being increased.”            From this
    19
    Case: 18-31074      Document: 00515618613         Page: 20    Date Filed: 10/28/2020
    No. 18-31074
    testimony, the jury was more than justified in finding Jones guilty of
    conspiracy to violate the anti-kickback statute.
    B
    As to whether there was insufficient evidence to find him guilty on
    Counts 18 and 22 through 27, Jones does not appear to contest that the patient
    named in each count was ineligible for home health services. Instead, he
    contends there was insufficient evidence he knew the patients were ineligible
    when he certified them for such services, thereby preventing him from being
    convicted of health care fraud.
    However, the previously addressed statistical evidence and his financial
    motive to falsify certifications are both circumstantial proof of knowledge.
    Jones likewise told one of his employees that Crinel was not receiving the
    number of patients she expected and that the employee needed “to schedule
    more health fairs” in order “[t]o find patients.” This evidence suggests that
    Jones’s unnecessary referrals were done with intent to deceive. 58 Considered
    together, this evidence is sufficient for a jury to conclude that Jones’s actions
    were fraudulent.
    IV
    Henry Evans was convicted of five counts of substantive health care
    fraud. Count 31 concerned patient JoWi and Counts 43 through 46 concerned
    patient MaGr. He challenges his convictions and his sentence.
    A
    Whether there was sufficient evidence to convict Evans as to Count 31 of
    the indictment is complicated by the fact that both Evans and the government
    58  See United States v. Gibson, 
    875 F.3d 179
    , 186 (5th Cir. 2017) (indicating that a
    persistent focus on the number of patients being referred for health care services can be
    indicative of fraudulent intent).
    20
    Case: 18-31074    Document: 00515618613     Page: 21   Date Filed: 10/28/2020
    No. 18-31074
    confused the true identity of patient JoWi. In 2009, Evans had originally
    treated a patient named JoWi (JoWi1). In 2013, he was asked to certify a
    different patient with the same first and last name as JoWi1 for home health
    care (JoWi2).   Evans did so without meeting her.        According to his trial
    testimony, he had certified JoWi2 for home health care under the mistaken
    belief that she was in fact JoWi1.
    During the investigation of this case, the case agent discovered the 2013
    JoWi2 home health certification. The case agent mistakenly believed that
    JoWi2 and JoWi1 were one in the same and that Evans had certified JoWi1 for
    home health care when he had not seen her since 2009. As a result, the
    government alleged the following in the indictment:
    Medicare Beneficiary JoWi: It was further part of the scheme to
    defraud that Medicare beneficiary JoWi began home health at
    Abide after she was referred by her treating physician to home
    health for wound care after a hospitalization. Beginning in July
    2013, E[vans] began certifying JoWi for home health at Abide,
    even though the last documented visit E[vans] had with JoWi was
    in October 2009. E[vans] certified JoWi for at least two (2)
    additional episodes of home health at Abide between July 2013 and
    February 2014.
    At trial, the case agent attempted to clarify the issue for the jury. Evans
    reinforced his understanding of events when he testified in his own defense.
    On appeal, Evans contends the aforementioned confusion led to either
    an impermissible constructive amendment of the indictment or a sufficiency-
    of-the-evidence issue.
    1
    Evans argues that the indictment’s confusion between JoWi1 and JoWi2
    resulted in a constructive amendment of the indictment in violation of the Fifth
    Amendment of the Constitution. But Evans only fully addresses the merits of
    this argument in his reply brief. It is well settled in this circuit that “a
    21
    Case: 18-31074         Document: 00515618613         Page: 22     Date Filed: 10/28/2020
    No. 18-31074
    defendant waives an issue if he fails to adequately brief it.” 59 We consequently
    do not consider this issue.
    2
    Evans contends that the confusion about JoWi resulted in a sufficiency-
    of-the-evidence issue. Evans argues that if Count 31 referenced JoWi1, there
    was no evidence he ever fraudulently certified her for home health care. Thus,
    he could not be convicted on that count. He also argues that the same result
    holds if Count 31 referenced JoWi2 because there was insufficient evidence to
    prove the conduct was criminal. He argues there was no evidence showing that
    JoWi2 was ineligible for home health care or that his certification of her for
    home health care was done with the requisite fraudulent intent. Additionally,
    Evans argues his “mistake of fact” defense—namely, that he mistook JoWi1 for
    JoWi2—prevents him from being convicted. Evans is not entitled to relief
    under either premise.
    As an initial matter, we note that we need not and therefore do not
    address whether there was sufficient evidence introduced as to Count 31 if that
    count was intended to refer to JoWi1. The indictment can be read to suggest
    Count 31 intended to reference JoWi1. But any resulting confusion in the
    indictment as to the “true identity” of JoWi was eliminated at trial once the
    government’s case agent and Evans himself testified. At that point, all parties
    involved—including the jury—understood Count 31 concerned JoWi2, and
    specifically, that the issue was whether the certification pertaining to that
    patient constituted fraud. Because the jury in this case was amply aware that
    Count 31 turned on whether the JoWi2 billing was fraudulent, we need only
    consider whether sufficient evidence was offered to support that count.
    59   See United States v. Martinez, 
    263 F.3d 436
    , 438 (5th Cir. 2001).
    22

    No. 18-31074
    The jury heard evidence that Evans twice certified JoWi2 as homebound,
    under his care, and in need of skilled services even though he had never met
    her.    There was evidence suggesting that certification was done with
    fraudulent intent. The circumstances surrounding the JoWi certification were,
    to say the least, suspicious. Evans’s defense to this claim amounted to a self-
    serving admission that he mistakenly believed JoWi2 to be JoWi1—a patient
    he had not seen or treated in nearly five years. The jury was entitled to judge
    Evans’s veracity and to reach the opposite conclusion. Moreover, the inference
    of fraud that arises from the suspicious circumstances surrounding JoWi’s
    certification becomes only stronger when one considers the ample evidence
    offered at trial that Evans had knowingly and falsely certified another patient,
    MaGr, as homebound. Upon collectively viewing this evidence, “it was not
    unreasonable for the jury to discredit Evans’[s] self-serving testimony, draw
    rational inferences from [his] actions, and find him guilty [on Count 31].”
    Contrary to Evans’s arguments, the record contained sufficient evidence to
    establish each element of the charged offense.

    For Counts 43 through 46, the indictment specifically alleged that Evans
    fraudulently billed Medicare for two episodes of home health care, the first
    episode beginning on April 1, 2012 and the second on November 27, 2012. The
    Medicare Part A and Medicare Part B billings for each of those episodes
    constituted the four relevant counts. As to why these billings were fraudulent,
    the indictment alleged: (1) “Evans falsely certified [diagnosis codes] on MaGr’s
    485s that were not medically supported in his treatment of MaGr;” (2) Evans
    certified MaGr for two episodes of home health care even though she did not
    qualify for home health care; and (3) Evans billed Medicare for care plan
    oversight of patients in home health care for 30 minutes or more each month
    despite the fact that he did not provide the requisite services.

    No. 18-31074
    Importantly, the theories of fraud identified in the indictment are merely
    theories as to why each billing constituted fraud.              When evaluating the
    sufficiency of the evidence, we are concerned with the “essential elements of the
    crime.” 60 Thus, on appeal, Evans must demonstrate insufficient evidence of
    each of these three allegations in order to merit a reversal.
    The    jury    heard    evidence    demonstrating       that,   despite    Evans’s
    certifications to the contrary, MaGr was ineligible for home health care. Dr.
    Lutz provided testimony that MaGr “didn’t seem to have any trouble getting
    around.” Dr. Lutz also noted that there was no “indication in any medical
    record that supports [classifying MaGr as] homebound.” Dr. Lutz stated that
    MaGr was certified for thirty-two episodes of care. He conceded that MaGr
    may have qualified for services at some point. Nevertheless, she did not need
    skilled nursing services continuously for that period. Coupled with the fact
    that Evans had a financial interest in home health referrals, there was
    sufficient evidence to establish that the two Medicare Part A billings and two
    Medicare Part B billings identified in Counts 43 through 46 constituted fraud.
    C
    Evans asserts that the district court erred when it allowed Dr. Lutz to
    testify as an expert witness. Dr. Lutz testified on behalf of the government as
    “an expert in the field of internal medicine and the medical necessity of home
    health services.” Out of the presence of the jury, the government presented
    Dr. Lutz’s qualifications to the court. The prosecution elicited, inter alia, that
    Dr. Lutz: (1) received his medical doctorate from Tulane University School of
    Medicine and a master’s degree in public health from Tulane University School
    of Public Health and Tropical Medicine; (2) previously served as the Director
    60 Gibson, 875 F.3d at 185 (emphasis added) (quoting United States v. Vargas-Ocampo,
    
    747 F.3d 299
    , 303 (5th Cir. 2014) (en banc)).

    of Health for the City of New Orleans; (3) received numerous awards
    throughout his career; and (4) had previously taught at Tulane University.
    The defense challenged Dr. Lutz’s qualifications by eliciting, inter alia, that
    (1) he had never before testified “regarding the medical necessity [of] home
    health services;” (2) he had “never studied home health;” and (3) that Dr. Lutz
    had never seen several of the patients about whom he was called upon to
    testify. The judge qualified Dr. Lutz as an expert.
    Dr. Lutz testified on a variety of subjects. He provided insight into the
    various medical conditions identified in each patient’s file, pointed out
    apparent contradictions between a physician’s proposed treatment plan and
    the patient’s complaints, and addressed whether a patient needed skilled
    nursing services. Dr. Lutz also testified that the patients identified in the
    indictment “may have needed home health for short periods of time, but none
    of them needed it for the continuous periods of time that [they] were
    consistently certified and recertified for.” He was subject to vigorous cross-
    examination by defense counsel.
    On appeal, Evans contends that the admission of Dr. Lutz’s testimony
    constituted error.      Evans’s primary contention is that “Dr. Lutz’s
    testimony . . . [was] not based on the ‘reliable principles and methods’ relevant
    to this case—the Medicare regulations.” He specifically points to a bench
    conference in which counsel for the government acknowledged that (1) Dr. Lutz
    was not asked “anything about the regulations” during direct examination and
    (2) knowledge of the regulations was “out of [Dr. Lutz’s] experience.” Evans
    notes that the district court acknowledged that Dr. Lutz was not qualified to
    speak about the relevant regulations. Addressing Dr. Lutz’s testimony, the
    court noted the following:
    But he hasn’t testified -- all he -- he has said in his opinion as a
    doctor making a decision about whether someone needs home
    25

    health care services, that that would have an impact on his
    thoughts about whether they needed it. Now, whether that
    technically under the Medicare regulations affects the
    determination, I don’t think this witness is qualified to testify
    about that.
    Evans argues that “[t]he district court’s statement is remarkable, given that
    Dr. Lutz had just finished two days of testimony as the [g]overnment’s ‘expert,’
    [during which] he stated definitively that in his expert opinion the eight
    patients named in the indictment were not ‘homebound.’”
    Evans also alleges Dr. Lutz had a “highly flawed view of home health
    care.” Evans points to transcript excerpts in which Dr. Lutz acknowledges that
    his definition of “homebound” differs from Medicare’s:
    My definition -- or my thinking of homebound is when somebody
    has an illness where they literally can’t get out of the house
    without doing an ambulance or something, or where it takes an
    army or a village or something to get them out. I think that the --
    I think that the Medicare definition that you’re talking about in
    Chapter 7 is liberal and allows home health care to a larger
    number of people . . . .
    This testimony is concerning, Evans argues, because he “was being tried for
    fraudulently violating the Medicare regulations[,] not violating Dr. Lutz’s
    personal definition of ‘homebound.’” He alleges that “an opinion divorced from
    [Medicare’s] regulation[s] is unreliable and therefore, inadmissible.”       The
    district court’s refusal to read the applicable Medicare regulations to the jury,
    Evans contends, “compounded” the error created by admitting Dr. Lutz’s
    testimony.
    When evaluating the propriety of expert testimony, we turn to the
    Federal Rules of Evidence, which dictate the admission of expert testimony in
    federal trials. Under Rule 702, “[a] witness who is qualified as an expert by
    knowledge, skill, experience, training, or education may testify in the form of
    an opinion or otherwise if:” (1) the testimony is helpful to the trier of fact,
    26

    No. 18-31074
    (2) “the testimony is based on sufficient facts or data,” (3) “the testimony is the
    product of reliable principles and methods,” and (4) “the expert has reliably
    applied the principles and methods to the facts of the case.” 61 Thus, “[e]xpert
    testimony is admissible only if it is both relevant and reliable.” 62
    “A trial court’s decision to admit expert evidence is reviewed for abuse of
    discretion.” 63 As a general matter, district courts are afforded “wide latitude”
    when it comes to the admissibility of expert testimony. 64 Thus, this court will
    only disturb the district court’s decision to admit expert testimony if the
    decision was “manifestly erroneous.” 65 “A manifest error is one that ‘is plain
    and indisputable, and that amounts to a complete disregard of the controlling
    law.’” 66 Even if this court concludes the district court did err when it admitted
    expert testimony, this court will not reverse a defendant’s conviction if the
    error was harmless. 67
    Here, the district court’s decision to admit Dr. Lutz’s testimony did not
    constitute an abuse of discretion. Evans’s contentions on appeal turn on the
    scope of Dr. Lutz’s testimony. As previously stated, Dr. Lutz was allowed to
    offer his opinions as “an expert in the field of internal medicine and the medical
    necessity of home health services.” Within those parameters, Dr. Lutz was
    qualified to testify about a variety of topics.           After reviewing a relevant
    patient’s medical records, he was capable of (1) defining medical terminology,
    (2) identifying apparent contradictions between a physician’s treatment plan

    and a patient’s complaints, (3) opining as to whether a patient needed skilled
    nursing care, and (4) analyzing whether a patient’s medical file supported his
    or her physician’s conclusion that he or she suffered from a particular
    condition. A medical doctor with Dr. Lutz’s experience can answer questions
    about these topics after reviewing an individual patient’s medical records. The
    district court did not abuse its discretion to the extent it permitted Dr. Lutz to
    testify about these subjects.
    Whether Dr. Lutz was qualified to testify about the “medical necessity of
    home health services” is a more difficult question. Although the record is not
    entirely clear, the district court appears to have drawn a distinction between
    “the medical necessity of home health services” and whether the patient
    qualified for home health care under Medicare. For example, the district court
    noted the following during a bench conference:
    So [Dr. Lutz] was qualified as an expert in internal medicine and
    the medical necessity of home health services, which I interpreted
    to mean this was for -- and his testimony was more about, would
    this -- does this person need someone to come to their home?
    Would it be good for them for someone to come to their home as
    opposed to them going to the doctor’s office? But he was not, he
    was not qualified as an expert in Medicare regulations and he
    wasn’t questioned about that.
    The district court ruled that Dr. Lutz could offer his opinion as a practitioner
    as to whether a particular patient needed home health care. In contrast, Dr.
    Lutz could not testify about whether a particular patient qualified for home
    health care under Medicare.
    Allowing Dr. Lutz to testify about whether he believed a patient was
    homebound arguably may have injected confusion at trial. Evans correctly
    notes that “whether a patient is ‘homebound[]’ . . . is a medico-legal
    determination.” To the extent that the Medicare regulations provide guidance
    28
    Case: 18-31074      Document: 00515618613         Page: 29     Date Filed: 10/28/2020
    No. 18-31074
    as to which patients qualify as homebound, it is akin to a term of art. But the
    word also has meaning outside of these parameters.
    At numerous times throughout Dr. Lutz’s testimony, Dr. Lutz noted that
    certain patients were not homebound. But, for many of these occasions, Dr.
    Lutz failed to clarify whether his determination was based on his own
    definition of homebound or on Medicare’s. Dr. Lutz’s testimony as to his
    comparatively conservative view of home health care’s requirements only
    served to further complicate the matter. For borderline cases, there thus
    existed a very real possibility that a patient would have qualified for home
    health care under Medicare while also not being homebound under Dr. Lutz’s
    standard. In these instances, Dr. Lutz’s determinations as to the homebound
    status of these patients could have, at a minimum, confused the jury. At worst,
    his determinations could have misled them. Nevertheless, the fact that Dr.
    Lutz’s determinations could have confused or potentially misled the jury fails
    to amount to an abuse of discretion by the trial court.
    The fact that some of Dr. Lutz’s testimony may have been potentially
    misleading or confusing comes close, but ultimately does not amount to a “plain
    and indisputable” error. 68 Nor can we conclude it rises to the level of “a
    complete disregard of the controlling law.” 69 We are certainly troubled by some
    aspects of Dr. Lutz’s testimony.         Nevertheless, we cannot conclude these
    aspects of Dr. Lutz’s testimony amounted to manifest error. 70 Indeed, despite
    challenging Dr. Lutz’s qualifications, defense counsel did not object to specific
    questions eliciting, during direct examination, Dr. Lutz’s ambiguous
    assessment of patients’ homebound status and consequent need for home
    health services. Instead, counsel’s effective cross-examination resolved these

    ambiguities and clearly demonstrated for the jury that Dr. Lutz’s
    determinations were based on his own, more conservative view of which
    patients were in fact “homebound.” 71 Further, the “presentation of contrary
    evidence[] and careful instruction on the burden of proof” were other available
    means of adequately addressing any confusion that resulted from Dr. Lutz’s
    testimony. 72
    D
    Evans argues that the district court procedurally and substantively
    erred in imposing his sentence. His sentence turned largely on the amount of
    loss resulting from his fraudulent conduct. 73            During the intervening 16
    months between Evans’s conviction and sentencing, both Evans and the
    government presented each of their proposed loss calculations to the court.
    Four days prior to sentencing, Evans requested permission to cross examine a
    government witness as to the loss calculation and to present his own expert
    testimony concerning his proposed calculation at sentencing. The district court
    denied his request, noting that “evidence relevant to the loss allocation had
    been presented at the trial, that the parties have had the opportunity to do
    extensive briefing on the issue, and that, as a result, no live testimony will be
    allowed at the sentencing hearing.” The court permitted, however, “Evans to
    proffer his own expert’s testimony about loss calculations on the record at the
    conclusion of the hearing.” Evans filed a motion to reconsider two days before
    sentencing. He stressed that he had been prohibited “from putting on ‘evidence
    regarding the admission of worthy patients into home health care’ or ‘evidence

    of specific instances of uncharged proper Medicare billing[s]’ during the trial.”
    Thus, in his estimation, not all of the “evidence relevant to the loss allocation
    had been presented at the trial.” Nevertheless, the district court refused to
    reconsider its original ruling.
    At oral sentencing, the district court first defined what it considered to
    be each physician’s relevant conduct under section 1B1.3 of the Guidelines.
    The defendants collectively had engaged in jointly undertaken criminal
    activity. But the district court held that “the scope of [each physician’s] jointly
    undertaken criminal activity encompassed only the fraudulent conduct
    relating to each defendant[’s] own acts and patients.” Next, the court found
    that the actual loss resulting from Evans’s scheme exceeded his intended loss;
    thus, actual loss would be used to calculate his advisory range.                It then
    determined that actual loss in this case included “all Medicare payments made
    to both Abide and [Evans] for all of [Evans’s] patients.” Under this framework,
    actual loss included not only Evans’s fraudulent billings, but some legitimate
    billings as well. The court cited United States v. Hebron, however, which held
    that “whe[n] the government has shown that the fraud was so extensive and
    pervasive that separating legitimate benefits from fraudulent ones is not
    reasonably practicable, the burden shifts to the defendant to make a showing
    that particular amounts are legitimate.” 74 Here, the court concluded that the
    fraud was pervasive and Evans had failed to produce evidence demonstrating
    which bills were legitimate and which were fraudulent. Subsequently, the
    court found that the actual loss resulting from Evans’s offense totaled
    $1,262,043.

    Evans first contends that the district court’s “refusal to hold an
    evidentiary hearing on [the question of loss] violated [his] [d]ue [p]rocess
    rights.” According to Evans, an evidentiary hearing would have allowed him
    to “put forth evidence of both legitimate billings and legitimately rendered
    services [that could have been] deducted from the total loss amount.” To
    buttress his argument, he points to the apparent contradiction between the
    district court concluding Evans failed to produce evidence of legitimate billings
    and legitimately rendered services on the one hand, and, on the other hand,
    the district court’s refusal to permit an evidentiary hearing at which such
    evidence could have been presented.
    Evans’s contention requires us to look to the commentary to section
    6A1.3 of the Guidelines, which provides guidance as to the appropriate
    procedures when facts impacting sentencing are in dispute. 75 It instructs that
    “[w]hen a dispute exists about any factor important to the sentencing
    determination, the court must ensure that the parties have an adequate
    opportunity to present relevant information.” 76 “Written statements of counsel
    or affidavits of witnesses may be adequate under many circumstances.” 77 The
    commentary further provides that “[a]n evidentiary hearing may sometimes be
    the only reliable way to resolve disputed issues.” 78 In this circuit, a district
    court’s refusal to hold an evidentiary hearing is reviewed for an abuse of
    discretion. 79 “[W]e have recognized that there is no abuse of discretion when a

    defendant has an opportunity to review the PSR and submit formal objections
    to it.” 80
    Here, the district court did not abuse its discretion when it refused
    Evans’s request for an evidentiary hearing. Evans had ample opportunity
    prior to sentencing to present evidence relevant to the loss calculation.
    Affidavits and statements by counsel are but two examples. 81 Evans was given
    the opportunity to proffer his expert’s testimony about the loss calculations at
    the end of the hearing. It is ultimately the district court that must make the
    factual determinations relevant for sentencing purposes. 82 The district court’s
    decision that an evidentiary hearing was unnecessary should be given
    considerable deference by this court. 83           Here, its decision to not take live
    testimony prior to sentencing did not amount to an abuse of discretion based
    on this record.

    Next, Evans contends the methodology employed by the district court to
    calculate actual loss in this case was flawed. He raises three sub-arguments.
    a
    First, Evans challenges the district court’s decision to apply Hebron’s
    burden-shifting framework. 84 Specifically, he contends “there was no basis for
    the court’s conclusion that ‘the fraud in this case was pervasive and difficult to
    detect,’” thereby there was no basis to shift the burden to him to demonstrate

    No. 18-31074
    which, if any, billings were legitimate. He notes initially that this circuit has
    not yet articulated which standard of review applies to a court’s determination
    that a particular fraud is pervasive. 85 Because “this determination constitutes
    a ‘method’ of determining the loss amount,” however, he argues de novo review
    should apply. As to the merits of his contention, he points to the fact that he
    “was acquitted of both conspiracy charges[] and convicted only of fraud with
    regard to three episodes of care.” Moreover, he notes that the government
    failed to offer any evidence of fraud relating to treatment of patients not
    identified in the indictment. “Consequently,” he argues, “there was no basis
    for the court’s conclusion that ‘the fraud in this case was pervasive and difficult
    to detect.’” To the extent Abide may have been engaged in a pervasive fraud
    with other physicians, “there was no such showing with regard to [Evans].”
    We conclude that clear-error review is the appropriate standard.
    Admittedly, the standard of review for loss determinations is somewhat
    complicated. We “consider [de novo] how the [sentencing] court calculated the
    loss, because that is an application of the [G]uidelines, which is a question of
    law.” 86 “[Clear-error] review applies to the background factual findings that
    determine whether . . . a particular method is appropriate.” 87 If we affirm the
    district court’s methodology under this framework, we then review the
    application of the methodology to the facts of the particular case for clear
    error. 88
    With those standards in mind, one can plausibly categorize Hebron’s

    would be subject to de novo review. But we believe it is more appropriate to
    define a district court’s “pervasiveness determination” as a background factual
    finding that informs the ultimate methodology employed by the court. After
    all, the district court must first determine that a fraud is pervasive before
    invoking the procedures outlines in Hebron. 89 We therefore review Evans’s
    first argument, which concerns a factual determination by the district court,
    for clear error.
    Under that standard, we agree with the district court that Evans’s fraud
    was pervasive. The statistical evidence presented during trial concerning case-
    mix diagnoses is persuasive. The case-mix diagnoses codes were “used to
    increase [Abide’s] Medicare[] reimbursement[s].” Dr. Solanky, a government
    witness, provided statistical evidence regarding seven of the codes.                       Dr.
    Solanky’s testimony indicated that a greater percentage of Evans’s patients
    had been diagnosed with each of those diagnostic codes than other providers
    in Louisiana. For six of the diagnostic codes, the disparity was statistically
    significant, meaning they did not occur “by . . . chance.”                 In light of this
    evidence, the district court’s conclusion that Evans’s fraud was pervasive is
    more than plausible. 90 We will not disturb the district court’s decision to apply
    Hebron’s burden-shifting framework in this case.
    b
    Second, Evans argues the district court failed to make the requisite
    findings that he engaged in a conspiracy with Abide. He relies on United States
    v. Jimenez, an unpublished case, to support his argument. 91                      There, the
    defendant had been found guilty of conspiracy to possess with intent to

    , 942
    (5th Cir. 1994)) (“A factual finding is not clearly erroneous if it is plausible in light of the

    distribute marijuana. 92 At sentencing, the district court determined that the
    defendant’s “jointly-conducted activity” extended to a separate drug
    transaction involving cocaine. 93      This court vacated and remanded for
    resentencing “[b]ecause the record reflect[ed] no explicit finding regarding
    whether the distribution of cocaine was within the scope of the criminal
    activity that [the defendant] agreed to undertake.” 94
    Evans argues that if the district court wanted to hold him liable for
    Abide’s fraudulent acts, the court must first specifically find that those acts
    were “(i) within the scope of the jointly undertaken criminal activity, (ii) in
    furtherance of that criminal activity, and (iii) reasonably foreseeable in
    connection with that criminal activity.” 95 He asserts that “the district court
    only addressed the ‘scope’ of [his] relevant conduct, which it defined as
    ‘fraudulent conduct relating to [Evans’s] own acts and . . . patients.’” Without
    addressing the remaining two requirements, Evans contends, the district court
    could not hold him liable for anything other than his own actions, actions which
    included nothing more than “the amount [Medicare] paid for JoWi and MaGr
    in the counts of conviction.”
    Ultimately, however, Evans’s argument is without merit. Admittedly,
    the sentencing transcript does suggest that the district court only directly
    addressed section 1B1.3(a)(1)(B)’s first requirement, namely whether Abide’s
    conduct was “within the scope of the jointly undertaken criminal activity.” 96 It
    noted, “[t]he [c]ourt finds as a matter of fact that the scope of Barnes, Evans,
    Michael Jones, and . . . Molden’s jointly undertaken criminal activity
    encompassed only the fraudulent conduct relating to each defendant[’s] own

    No. 18-31074
    acts and patients.” The court did not appear to have expressly addressed the
    remaining two requirements.
    Nevertheless, the district court implicitly recognized that the remaining
    two requirements were satisfied. The district court went to great pains to
    follow Fifth Circuit precedent during sentencing.             The court noted it was
    required to expressly find each of section 1B1.3(a)(1)(B)’s requirements. It
    then outlined why the government’s articulation of each defendant’s relevant
    conduct—namely, that each physician was in a conspiracy not merely with
    Abide, but with each of the other physicians—did not satisfy those
    requirements. Thereafter, the district held that “the scope of [each physician’s]
    jointly undertaken criminal activity encompassed only the fraudulent conduct
    relating to each defendant[’s] own acts and patients.” Viewed in context, the
    record thus suggests the district court believed the remaining two
    requirements were met as well. That is, by first outlining the requirements,
    then rejecting the government’s articulation of each defendant’s jointly
    undertaken criminal activity, and finally concluding that a different
    articulation was more appropriate, the judge implicitly recognized that its own
    articulation met section 1B1.3(a)(1)(B)’s requirements.
    Moreover, as this court noted in United States v. Puig-Infante, district
    courts are permitted “to make implicit findings by adopting the PSR.” 97 Here,
    the district court adopted the PSR’s factual findings, which thoroughly
    described the overall conspiracy and Evans’s role in it.
    c
    Third, relying on evidence proffered after sentencing, Evans argues that
    “the district court erroneously included billings that occurred both before and

    19 F.3d 929
    , 943 (5th Cir. 1994) (quoting United States v. Carreon,

    Case: 18-31074         Document: 00515618613         Page: 38     Date Filed: 10/28/2020
    No. 18-31074
    after [Evans’s] agreement with Abide.” By his calculations, his actual-loss
    total is reduced by $52,947.
    Because Evans’s contention does not affect his Guidelines calculation, it
    is only necessary to consider his argument as it relates to the court’s restitution
    order.        The district court ordered restitution in this case pursuant to the
    Mandatory Victim’s Restitution Act of 1996 (MVRA). 98 “The MVRA authorizes
    restitution to a victim ‘directly and proximately harmed’ by a defendant’s
    offense of conviction.” 99 Restitution orders are reviewed under an abuse of
    discretion standard, 100 with factual findings reviewed for clear error. 101
    Importantly, “[a]n award of restitution greater than a victim’s actual loss
    exceeds the MVRA’s statutory maximum.” 102
    Under these standards, we will not vacate Evans’s restitution order. We
    assume without deciding that we may consider the evidence Evans proffered
    after sentencing. Nevertheless, this evidence does little to call into question
    the district court’s calculations. The loss calculation in this case turned, in
    part, on the length of time Evans participated in the conspiracy. As a result,
    Evans’s proffered report turns largely on the case agent’s opinion as to when
    Evans’s involvement in the conspiracy started and ended. According to Evans’s
    expert, the case agent concluded that Evans was involved in a conspiracy with
    Abide from September 29, 2011 through January 31, 2014. But because the
    government exhibits used to calculate actual loss covered more than just that
    particular period, Evans’s expert concludes that the government exhibits

    “include claims that are outside of the time period of [Evans’s] business
    affiliation with Abide.” Importantly, though, the district court’s determination
    as to Evans’s start and end dates differed from the government’s case agent.
    Notably, although Evans proffered his expert’s report after sentencing,
    the expert report was drafted two days before sentencing. The expert therefore
    could not have known before writing the report that the district court would
    select different start and end dates for Evans’s conspiracy than those suggested
    by the case agent. In contrast to the case agent, the court concluded that the
    start and end dates for Evans’s involvement in the conspiracy were September
    11, 2011 and June 9, 2014, respectively.
    Ultimately, Evans’s proffered report does little to challenge the district
    court’s restitution order and hardly demonstrates that the district court’s
    factual findings were clearly erroneous. We therefore decline Evans’s request
    to remand his case to the district court for resentencing.
    E
    Lastly, Evans contends the district court substantively erred during his
    sentencing. He argues the district court “failed to consider [several] categories
    of evidence in determining the loss amount.” Specifically, he points to the types
    of evidence he would have offered at an evidentiary hearing: (1) “additional
    evidence[] to rebut the presumption that the amount billed accurately depicts
    the loss amount;” (2) “evidence of . . . legitimate billings;” and (3) “evidence
    of . . . legitimately rendered services.” After considering the totality of the
    circumstances,      though,     we    believe     his     sentence   was    substantively
    reasonable. 103 Sentences within the correctly calculated Guidelines range are
    103 See Gall v. United States, 
    552 U.S. 38
    , 51 (2007) (“When conducting [a review of
    the substantive reasonableness of the sentence], the court will, of course, take into account
    the totality of the circumstances, including the extent of any variance from the Guidelines
    range.”).

    No. 18-31074
    afforded a presumption of reasonableness. 104                   Here, Evans’s correctly
    calculated advisory Guidelines range called for between 63 and 78 months in
    prison. The court granted a downward variance to 50 months in prison. This
    below-Guidelines sentence is afforded a presumption of reasonableness in this
    court and Evans has not sufficiently rebutted that presumption. We therefore
    affirm his sentence.

    A
    Paula Jones’s first issue on appeal concerns whether the government
    produced sufficient evidence to convict her of conspiracy to commit health care
    fraud (Count 1) and conspiracy to violate the anti-kickback statute (Count 2).
    As to Count 1, Jones, like her co-defendants, had a financial incentive to
    engage in a conspiracy to commit health care fraud. The government also
    presented evidence demonstrating: (1) Jones’s awareness that Abide needed to
    bill $2,100 to break even for each home health care episode; (2) the fact that
    she would generate reports monitoring the average revenue for home health
    episodes weekly; (3) the fact that when a bill did not reach $2,100, she would
    “g[i]ve the files back to the case managers to see if they could get the score up
    to at least $2,100[;]” (4) the fact that she routed one of Michael Jones’s billings
    without his required signature; and (5) the fact that Jones, as Abide’s biller,
    routed each of the physicians’ fraudulent bills to Medicare. Further, evidence
    that she had “a ‘911’ code” in the event law enforcement arrived also provided
    circumstantial evidence that she was aware criminal activity was afoot.

    As to Count 2, Jones’s awareness of the fact that her salary was tied to
    Michael Jones’s referrals, her continued receipt of that salary, and her 911 code
    are more than enough for a rational jury to conclude that she agreed to
    participate in a conspiracy involving health care kickbacks.
    B
    Jones maintains that the district court erred when it refused to sever her
    from trial with the other defendants. Numerous times during trial, Jones
    moved under Rule 14 for relief from prejudicial joinder. Under Rule 14, “[i]f
    the joinder of offenses or defendants in an indictment, an information, or a
    consolidation for trial appears to prejudice a defendant or the government, the
    court may order separate trials of counts, sever the defendants’ trials, or
    provide any other relief that justice requires.” 105 The trial court denied each
    of those requests. On appeal, Jones argues the district court’s refusal to sever
    her trial from the remaining defendants constituted error. She argues a joint
    trial resulted in prejudicial spillover and argues that the judge’s limiting
    instructions inadequately addressed the prejudicial effect of a joint trial. We
    disagree.
    “We review the denial of a motion to sever a trial under the exceedingly
    deferential abuse of discretion standard.” 106 Severance under Rule 14 is proper
    “only if there is a serious risk that a joint trial would compromise a specific
    trial right of one of the defendants, or prevent the jury from making a reliable
    judgment about guilt or innocence.” 107 “[A] defendant ‘must prove that: (1) the
    joint trial prejudiced him [or her] to such an extent that the district court could

    not provide adequate protection; and (2) the prejudice outweighed the
    government’s interest in economy of judicial administration.’” 108
    Here, the district court did not abuse its discretion when it refused to
    grant Jones’s request for a separate trial. Jones’s argument relies heavily on
    her assertion that evidence aimed at her co-defendants would likely spillover
    into her case. But the evidence adduced against the remaining defendants was
    largely relevant to Jones’s conduct as well. The substantive evidence adduced
    against the remaining defendants largely established a “culture of fraud” at
    Abide. That same evidence, the district court noted, was relevant to whether
    “employees, like [Jones], knew or should have known that their activities were
    part of a conspiracy to defraud Medicare.” Jones thus largely exaggerates the
    spillover risks in this case.
    Moreover, the district court’s instructions adequately alleviated the risk
    of unfair prejudice. The district court’s instruction to consider each count
    separately was “sufficient to prevent the threat of prejudice resulting from [a
    joint trial].” 109 Likewise, the district court did not err in refusing to read
    Jones’s hand-crafted instructions—instructions Jones contends would have
    further reduced the risk of unfair prejudice. The district court refused to read
    her proposed instructions because they were more akin to a closing argument,
    than jury instructions. We have “repeatedly rejected requested instructions
    that are ‘more in the nature of a jury argument than a charge,’” and do so again
    here. 110
    As the district court correctly noted, “[t]he rule, rather than the
    exception, is that persons indicted together should be tried together, especially

    in conspiracy cases.” 111 Jones fails to explain adequately why her case is the
    exception and not the rule. The district court did not abuse its discretion when
    it declined to grant Jones’s severance motion.
    C
    We next consider if the district court procedurally erred when calculating
    the total-loss amount applicable to Jones’s sentence and restitution order.
    Jones’s advisory Guidelines range and her restitution order turned on
    the amount of loss resulting from the fraud. The court ultimately concluded
    that “the reasonably foreseeable pecuniary harm” in this case was
    $3,106,954. 112 It arrived at that figure by first determining that Abide had
    billed $4,124,591.20 to Medicare during the relevant period and then reducing
    that total by 32 percent because Jones was only logged into Kinnser for 68
    percent of the relevant time period.
    On appeal, Jones contends the district court procedurally erred in
    calculating her advisory sentence.         She also alleges the district court’s
    restitution order, which mirrored the district court’s loss-calculation, was
    inflated. She argues that “[t]o hold her accountable for a loss amount of over
    $3 million vastly exaggerates her very limited role in the alleged conspiracy.”
    She contends the district court erred when it concluded that all of Abide’s
    Medicare billings were foreseeable losses. “As a biller for the company,” she
    notes, “she would have no way of knowing whether . . . the doctors had actually
    seen    the   patients   in   question,    let   alone   whether     those   patients
    actually . . . qualified for home health care.” To demonstrate the significance

    of the district court’s error, Jones notes her loss amount was substantially
    greater than all of the physicians in the conspiracy.
    We review sentencing decisions to ensure they are reasonable. 113 Jones
    specifically challenges the district court’s loss calculation and its effect on the
    advisory Guidelines calculation. If correct, her allegation would constitute
    significant procedural error. 114 As to the standard of review applied to Jones’s
    appeal, Jones takes issue with the factual predicates underlying the district
    court’s methodology. That is, she argues the district court erred insofar as it
    determined that all billings Jones approved using Kinnser were “the
    reasonably foreseeable pecuniary harm [of her] offense.” 115 Her contention is
    thus subject to clear-error review. 116
    Here, the district court’s factual finding survives clear-error review. The
    district court’s well-reasoned statement from the bench adequately justified its
    decision to hold Jones accountable for $3,106,954 in actual losses. The district
    court noted that (1) “Jones participated in all of Abide billings, including
    fraudulent billings;” (2) “her awareness of the fraud was much more extensive”
    than she alleges; and (3) “her agreement to jointly undertake criminal activity
    extended to the entire reach of the conspiracy.” As previously outlined, these

    conclusions find adequate support in the record. The district court’s factual
    findings were thus plausible on the current record. 117
    The fact that Jones’s loss amount exceeded that of the physicians in the
    conspiracy is not determinative. Because actual loss calculations turn on
    foreseeability, 118 this result makes logical sense. One spoke of a conspiracy—
    a physician, for example, in a health care fraud scheme—may be unable to
    foresee the true scope of the conspiracy. But a person who processes each bill
    of an organization he or she knows is engaged in fraudulent conduct would be
    able to foresee the full scale of the fraud. 119 Thus, despite Jones’s contentions,
    the factual findings that formed the basis of the district court’s loss-calculation
    methodology are not clearly erroneous. For the same reasons, the district
    court’s restitution order survives appellate review. 120

    Gregory Molden argues that there was insufficient evidence to convict
    him of conspiracy to commit health care fraud (Count 1), conspiracy to violate
    the anti-kickback statute (Count 2), and eleven counts of substantive health
    care fraud (Counts 32 through 42).

    Medicare for these services, the billings were the direct and foreseeable result of DeHaan’s
    fraud as the gatekeeper in certifying the patients; without his certification, the agencies could
    not have billed Medicare and Medicare would not have compensated the agencies for the
    services they provided. The Medicare payments are a reasonable approximation of the loss
    resulting from DeHaan’s own criminal conduct . . . .”).

    Molden contends there was insufficient evidence to find him guilty of
    either conspiracy charge. As to Count 1, Crinel pleaded guilty to conspiring
    with Molden to commit health care fraud; evidence at trial suggested Molden
    had a financial incentive to join the conspiracy; and the statistical evidence is
    likewise probative of Molden’s guilt. The evidence related to each of Molden’s
    substantive health care fraud counts similarly reinforces the jury’s conclusion
    that Molden’s actions were fraudulent. Together, this evidence is more than
    enough for the jury to conclude that Molden participated in a conspiracy to
    commit health care fraud.
    The evidence presented as to Count 2 is perhaps even more compelling.
    Evidence presented at trial suggested Molden was paid $5,000 a month to work
    for Abide. Before Molden entered into this arrangement with Abide, he had
    several form 485s at Abide that had yet to be signed. According to Crinel, “in
    order for him to sign the 485s and to continue to send patients to [Abide], he
    wanted a salary.” Wilneisha Jakes also testified that Molden was being paid
    for patient referrals. Coupled with the fact that Crinel admitted to paying
    Molden kickbacks, there was more than enough evidence to convict Molden on
    Count 2.

    Likewise, Molden contends there was insufficient evidence to convict him
    of substantive health care fraud. Counts 32 through 37 related to patient
    KeTr. Counts 38 to 42 related to patient ShBe. Unlike his co-defendants who
    argued they were unaware their patients did not qualify for home health care,
    Molden seems to argue his patients did qualify for these services.
    As to patient KeTr, the jury could reasonably infer from Dr. Lutz’s
    testimony that this patient did not qualify for home health care. Molden had
    qualified KeTr for home health care because the patient suffered from Type 2
    46

    diabetes. But as Dr. Lutz noted, “Molden ordered blood tests on the same day
    he admitted [KeTr] to home health, and those blood tests came back [within
    normal levels].” Thus, according to Dr. Lutz, KeTr’s diabetes was “perfectly
    controlled.” Dr. Lutz also testified that nurses had difficulty locating KeTr
    while he was receiving home health care. During several visits to KeTr’s home,
    nurses would knock on the door, but no one would answer.             The logical
    inference from such evidence is that KeTr was not, in fact, homebound. In fact,
    he was eventually disenrolled from home health care after nurses could not
    locate him.    Together, this evidence more than suggests KeTr was not
    homebound when Molden certified him for home health care. There was thus
    sufficient evidence to convict Molden of substantive health care fraud with
    regard to his treatment of KeTr.
    As for patient ShBe, the evidence was also sufficient to convict Molden
    of substantive health care fraud. Dr. Lutz testified that: (1) ShBe’s patient file
    lacked documentation to support Molden’s diagnoses; (2) ShBe’s diagnoses
    were shuffled; and (3) ShBe was not home during several home health visits.
    As an example of suspicious certifications, Dr. Lutz noted that eight days prior
    to Molden recertifying ShBe for an episode of home health care based on
    hypertension, her blood pressure had been normal. He further opined that
    ShBe did not require skilled nursing care. The jury could reasonably have
    concluded that ShBe did not require home health care.
    B
    Like Barnes, Molden argues the district court erred when it refused to
    read several Medicare instructions to the jury.       For the reasons outlined
    earlier, the court did not abuse its discretion when it refused to read the
    proffered instructions to the jury.

    C
    Like Evans, Molden argues the district court erred in permitting Dr.
    Lutz to testify as an expert. For the reasons outlined earlier, the court’s
    decision to permit such testimony did not amount to an abuse of discretion.
