    Before WILLIAM PRYOR, Chief Judge, LUCK, and ED CARNES, Circuit
    Judges.
    ED CARNES, Circuit Judge:
    USCA11 Case: 19-14548             Date Filed: 04/12/2022         Page: 3 of 37
    19-14548                   Opinion of the Court                                 3
    Medicare and Medicaid combined spend $1,500,000,000,000
    a year, which is more than one-third of the total health expendi-
    tures in this country.1 Like other government health care pro-
    grams, these two work on the honor system. Trust and more trust.
    Both programs take a pay first, ask questions later (if ever) ap-
    proach. Which leads to crime and more crime, both sooner and
    later.
    A trust-based system is only as good as the people who are
    trusted. Douglas Moss is one of those who was trusted but not
    trustworthy. 2 As a physician, he fraudulently billed Medicare and
    Medicaid for millions of dollars for visits to nursing home patients

    2 Moss was a physician at the time of the events in this case, but after he was
    convicted and sentenced, he surrendered his medical license. That fact is not
    included in the record, but we can take judicial notice of it as a publicly avail-
    able state agency record, a copy of which has been sent to the clerk for place-
    ment on the docket. See Ga. Composite Medical Bd., https://gcmb.myli-

    that he never made. Someone else with a lower billing rate made
    some of those visits, and others never took place.
    For his fraudulent conduct, Moss was convicted of conspir-
    acy and substantive health care fraud, sentenced to 97 months im-
    prisonment, ordered to pay restitution of about 2.2 million dollars,
    and ordered to forfeit around 2.5 million dollars. He appeals, chal-
    lenging the convictions, sentence, restitution amount, and forfei-
    ture amount, which is nearly every component of the judgment
    against him. And he loses on every component of his appeal.
    I. FACTUAL BACKGROUND
    To explain Moss’ crimes (what he did, not why he did it
    which is obvious) we will begin with how Medicare and Medicaid
    determine how much health care providers will be paid. Then we
    will turn to how Moss arranged his billing practices to defraud the
    programs.
    A. Medicare and Medicaid
    Medicare and Medicaid are federally funded health care pro-
    grams. To make things simpler, from this point forward we will
    focus on Medicare (which suffered the brunt of his fraud) with the
    understanding that what is said about it applies to Medicaid as well,
    except where noted.
    Medicare pays “claims,” which are requests by a health care
    provider to be “reimbursed” (paid) for services provided to Medi-
    care recipients. A claim contains a variety of information, includ-
    ing where the medical service was provided, the dollar amount
    USCA11 Case: 19-14548         Date Filed: 04/12/2022     Page: 5 of 37
    19-14548                Opinion of the Court                          5
    being billed to Medicare, and an identification number for the
    health care provider. It also contains a code for the procedure or
    service performed.
    Those codes are called the “CPT codes,” which stands for
    Current Procedural Terminology codes. CPT codes are a national
    uniform coding structure created for use in billing and overseen by
    the American Medical Association. They are used by all health in-
    surance companies and by Medicare and Medicaid. A code repre-
    sents at least two things: the procedure or service performed and
    the level of complexity involved in it. One type of procedure or
    service can have more than one CPT code because the same pro-
    cedure may, in some cases, be more complex than in others. Gen-
    erally, for any given category of procedure, the more complex the
    performance, the higher the number used for its code. In turn, a
    higher CPT code generally gets a higher reimbursement amount
    from Medicare.
    Most of the fraud in this case involves claims for visits to
    nursing homes, so we will use that area of care to illustrate how
    CPT codes work. When a patient enters a nursing home, a health
    care provider’s first visit with that patient is categorized as “initial
    nursing facility care,” which corresponds to a particular set of three
    CPT codes. The highest of those three is 99306. According to a
    CPT manual issued by the AMA, a 99306 coded visit “requires these
    3 key components: [a] comprehensive history; [a] comprehensive
    examination; and [m]edical decision making of high complexity.”
    Giving that code to a visit also means that the problem requiring
    USCA11 Case: 19-14548        Date Filed: 04/12/2022     Page: 6 of 37
    6                      Opinion of the Court                 19-14548
    admission to the nursing home is usually one of “high severity,”
    and that the health care provider’s visit typically takes 45 minutes.
    For later visits to nursing home patients, which are catego-
    rized as “subsequent nursing facility care,” there are four codes:
    99307, 99308, 99309, and 99310. For 99309, the CPT manual states
    that it requires two of the following three “key components”: a de-
    tailed interval history, a detailed examination, and medical decision
    making of moderate complexity. The manual also states that for a
    99309 coded visit: “[u]sually, the patient has developed a significant
    complication or a significant new problem” and “[t]ypically, 25
    minutes are spent at the bedside and on the patient’s facility floor
    or unit.” As for code 99310, the first two “key components” must
    be “comprehensive” instead of just “detailed” and the third must
    involve “[m]edical decision making of high complexity” instead of
    just “moderate complexity.” The manual states that “[t]he patient
    may be unstable or may have developed a significant new problem
    requiring immediate physician attention,” and that the visit typi-
    cally takes 35 minutes.
    For Medicare to pay a claim (or “reimburse” it), several re-
    quirements must be met. The service must be provided to a real
    patient who is properly enrolled as a Medicare beneficiary; it must
    be provided by a health care provider properly licensed and “en-
    rolled” as a Medicare provider; it must be a service covered by
    Medicare; and it must be properly documented and billed. The
    service also must be reasonable and medically necessary. Health
    care providers sign a “certification statement” agreeing that they
    USCA11 Case: 19-14548       Date Filed: 04/12/2022     Page: 7 of 37
    19-14548               Opinion of the Court                        7
    will comply with all of those requirements and will not submit false
    claims.
    When Medicare reimburses a claim, the amount that it pays
    is based on a predetermined fee schedule that it sets. A health care
    provider is free to submit a claim for a dollar amount that exceeds
    the amount in the fee schedule, but Medicare will not pay more
    than the schedule amount. It is common practice for physicians to
    submit claims exceeding the amount in the fee schedule, even
    though they know they won’t get reimbursed the excess amount.
    An important fact that determines how much Medicare pays
    the provider is whether the service was performed by a physician
    or a non-physician. In the nursing home setting, Medicare requires
    a distinction between non-physicians, or “mid-level practitioners”
    as they are called, and physicians. Physician’s assistants and nurse
    practitioners must bill at a rate that is only 85% of the physician’s
    rate.
    And to properly bill Medicare at the physician’s rate for ser-
    vices provided in a nursing home setting, the physician must be the
    one in the patient’s room directly providing the service to the pa-
    tient. When an assistant performs the service, the claim submitted
    to Medicare must disclose that fact.
    B. The Fraud Scheme
    Moss was the medical director and attending physician at
    four nursing homes. He recruited Shawn Tywon to be his physi-
    cian’s assistant and, as it turned out, his co-conspirator. Moss had
    USCA11 Case: 19-14548       Date Filed: 04/12/2022    Page: 8 of 37
    8                      Opinion of the Court               19-14548
    Tywon help with the nursing home patients, and he trained Tywon
    how to conduct visits with those patients.
    Between January 2012 and January 2015 Moss billed 31,714
    claims to Medicare for nursing home visits; 477 were coded as
    99306, the highest code for “initial nursing facility care.” And
    25,468 were coded as 99309, and 5,769 as 99310, which are the two
    highest codes for “subsequent nursing facility care.” In that three-
    year period, Moss billed $6,701,163.00 for those claims, and Medi-
    care reimbursed him $2,171,098.85. As for Medicaid, during that
    same three-year period, Moss billed 17,336 claims for those same
    codes, and Medicaid paid him $336,524.84. Nearly all of those
    claims were submitted to Medicare as though Moss had personally
    performed the services.
    Those numbers suggest a staggering amount of work, a
    seemingly impossible amount of it. And, as it turned out, that
    amount of work was impossible. The claims Moss submitted
    would have required him to see more than 50 patients a day for 293
    of the days in the three-year conspiracy period, and even more than
    100 a day on some days and more than 150 a day on other days.
    Not only that, but based on how long the CPT manual suggested
    those visits should take, Moss was sometimes billing Medicare for
    services that added up to more than 24 hours a day. He did that on
    275 days. And on some days he billed for services that would have
    taken him more than 70 hours on that day. The services Moss
    billed on one stellar day would have required him to put in nearly
    100 hours in that one 24-hour period. People sometimes wish there
    USCA11 Case: 19-14548        Date Filed: 04/12/2022     Page: 9 of 37
    19-14548               Opinion of the Court                         9
    were more hours in a day, but Moss alone miraculously stretched
    some of his days to far more than 24 hours.
    Of course, Moss’ miracle was non-miraculous, old-fashioned
    fraud. He obtained money to which he was not entitled by making
    statements that weren’t true, or failing to disclose what was true.
    One way he crammed into some days more services than any day
    could hold is by claiming he had performed services that others ac-
    tually had done. He did that so he could bill those services at the
    higher physician rate when payment should have been calculated
    at the lower rate due the non-physician who had actually per-
    formed the services. Typically, that non-physician was Tywon,
    who was his physician’s assistant, or it was a different employee
    who was a nurse practitioner. Moss specifically directed that those
    services be billed in his name at his higher rate even though he
    knew that because those services were performed by non-physi-
    cians they could lawfully be billed only at a lower rate.
    The claims submitted during two periods of time, which are
    the basis for the substantive counts against Moss, are examples of
    what he did. The first is a series of claims for nearly $52,000, which
    collectively represented that from February 1 through 5, 2014,
    Moss personally saw 234 Medicare patients and 134 Medicaid pa-
    tients in Georgia. The second is a series of claims for just over
    $80,000, which collectively represented that from June 10 through
    18, 2014, Moss personally had seen 345 Medicare patients and 193
    Medicaid patients in Georgia. Those two sets of claims are out-
    standing in the field of Moss’ fraudulent claims because, instead of
    USCA11 Case: 19-14548      Date Filed: 04/12/2022    Page: 10 of 37
    10                     Opinion of the Court               19-14548
    being in Georgia treating patients on those dates, as he claimed,
    Moss had been in Las Vegas gambling.
    Moss did not travel on only one fraudulent path. In addition
    to submitting claims that were fraudulent because he had not per-
    formed the services that he had billed in his name and at his rate,
    he submitted claims that were fraudulent in another way. He also
    submitted claims that were fraudulent because –– whoever he
    claimed had performed them –– they were for services that were
    medically unnecessary or did not involve the level of complexity
    indicated by the CPT codes that Moss put on those claims. Recall
    that between January 2012 and January 2015, Moss submitted
    31,714 claims for services that he represented were covered by the
    highest CPT codes, which were meant to reflect the most complex
    procedures or services and that typically required 25 to 45 minutes
    a visit. The reality was nowhere close.
    Tywon testified that “probably for 95 percent of the time or
    more” when he himself had visited a patient, “there was nothing to
    do.” Instead, what he would do is walk into the patient’s room, ask
    if everything was okay, and because a “majority of the time” the
    patient said he didn’t need anything, Tywon would then leave. He
    usually did not do a physical examination, take blood pressure, or
    check the patient’s pulse. As Tywon stipulated in his plea agree-
    ment, he would just “lay eyes” on the patients, spending only “3 to
    5 minutes with” them during visits, except for in the uncommon
    event that they had some actual medical need. According to him,
    there was no medical purpose for most of the visits and he did not
    USCA11 Case: 19-14548       Date Filed: 04/12/2022    Page: 11 of 37
    19-14548               Opinion of the Court                       11
    think he had any reason to be making them. Moss had him make
    the visit anyway and bill it at the highest code solely because Moss
    wanted to increase his payments from Medicare, which he did. In
    that way, Moss added another layer of fraud on top of billing in his
    name instead of Tywon’s name; he also billed for any services that
    were provided as if they were far more complex and time consum-
    ing than they actually were.
    The notes Tywon generated for his patient visits were en-
    tirely consistent with his testimony. They were typically copy-
    pasted from one visit to the next with the only changes being the
    date, a brief indication of what the patient was doing (like eating
    lunch or watching tv), and typically noted that there were “no
    changes” or “no complaints,” meaning there was nothing new that
    was wrong with the patient. Usually when Tywon wrote “no
    changes” instead of “no complaints,” it indicated that the patient
    was asleep when he visited and did not even wake up. That is a far
    cry from what the CPT manual required for the high codes Moss
    used to bill the visits: 25 minutes of time, a “significant new prob-
    lem,” and a detailed interval history or examination with medical
    decision making of moderate complexity.
    II. PROCEDURAL HISTORY
    A. Indictment and Trial
    Moss and Tywon were indicted for defrauding Medicare and
    Medicaid. The indictment alleged one count of conspiracy to com-
    mit health care fraud, in violation of 
    18 U.S.C. § 1349
    , and six
    USCA11 Case: 19-14548       Date Filed: 04/12/2022    Page: 12 of 37
    12                     Opinion of the Court                19-14548
    counts of health care fraud, in violation of 
    18 U.S.C. § 1347
    . The
    six substantive counts were for specific claims Moss submitted dur-
    ing the two time periods when he was in Las Vegas but billed Med-
    icare and Medicaid for seeing patients in Georgia. Tywon pleaded
    guilty to conspiracy and agreed to cooperate with the government.
    Moss went to trial. After a seven-day trial, a jury found him
    guilty on all counts. The jury had heard from several witnesses
    including Moss’ former employees, a person from a billing com-
    pany Moss had used, government investigators, and Tywon.
    Those witnesses testified to Moss’ intimate knowledge of Medicare
    and Medicaid’s reimbursement rates and coding policies, his in-
    structions to generate more (fraudulent) claims to bill to the two
    programs, and his instructions to bill all claims in his name and at
    the highest CPT codes despite his knowing that doing so was ille-
    gal. The jury also heard evidence about how the representations
    Moss made in the billings were impossible: his claiming to have
    performed more than 24 hours of services a day, his claiming to
    have seen over 50 patients a day, and his claiming to have seen pa-
    tients in Georgia when he was actually in Las Vegas. It wasn’t a
    close case.
    B. Sentencing
    Moss’ presentence investigation report recommended a
    guidelines range of 78 to 97 months. That range was based primar-
    ily on a loss of $6,701,163, which was the amount Moss had billed
    to Medicare and Medicaid; that factor alone caused an 18-level in-
    crease to his offense level. After much argument about the loss
    USCA11 Case: 19-14548       Date Filed: 04/12/2022    Page: 13 of 37
    19-14548               Opinion of the Court                       13
    amount, the district court adopted the PSR but reduced the loss
    amount by 10 percent to $6,031,046.70. That reduction was for
    what the court estimated to be the value of legitimate medical ser-
    vices that Moss had provided. The ten percent reduction to the
    loss amount did not, however, change the guidelines range.
    The court sentenced Moss to 97 months imprisonment, the
    top of the guidelines range. It also ordered him to forfeit
    $2,507,623.69 and to pay $2,256,861.32 in restitution. The forfei-
    ture amount was for the total that Medicare and Medicaid had paid
    to Moss, with no reduction for any legitimate services he had pro-
    vided. The restitution amount was what Medicare and Medicaid
    had paid Moss, with the 10 percent reduction based on the court’s
    estimate of the legitimate services Moss had provided.
    Moss moved for a new trial, which the district court denied.
    This is his appeal of his convictions and sentence, as well as of the
    restitution and forfeiture amounts.
    III. CONVICTION ISSUES
    As we said in another health care fraud case, Moss “raises
    [three] contentions about his convictions, [none] of which ques-
    tions the sufficiency of the evidence to convict him.” United States
    v. Pon, 
    963 F.3d 1207
    , 1219 (11th Cir. 2020). And none of which
    has any merit.
    A. The Testimony of Tywon’s Attorney
    Moss contends that the district court erred in quashing his
    subpoena of Tywon’s attorney, Miles Hannan. Moss argues he
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 14 of 37
    14                     Opinion of the Court               19-14548
    could have used Hannan’s testimony to impeach the testimony of
    Tywon, the government’s key witness. But that is not what attor-
    ney Hannan’s testimony would have done.
    1. Background
    As mentioned, Moss’ co-conspirator Shawn Tywon pleaded
    guilty to conspiracy and agreed to cooperate with the government.
    Part of Tywon’s plea agreement addressed his compensation dur-
    ing the conspiracy. It stated that “Tywon was paid $4500 bi-weekly
    by Moss . . . . Aside from his paychecks and occasional loans from
    Moss, Tywon received no other form of compensation.” Later,
    while being prepared by the prosecutor for his testimony at Moss’
    trial, Tywon revealed that he’d also received cash payments from
    Moss “on a semi-regular basis” and that Moss had occasionally paid
    some of his expenses.
    The government became concerned that Tywon had
    breached his plea agreement and that attorney Hannan might be
    disqualified from representing him. Acting on that concern, it filed
    a motion seeking clarification from the court of whether Hannan
    had a conflict of interest. The conflict, according to the motion,
    was that Tywon told the government he had not mentioned the
    cash payments sooner because “Hannan[] had instructed him not
    to mention receiving cash beyond his paychecks to the government
    ‘unless they specifically ask about it.’ Tywon indicated he
    had . . . acted under Attorney Hannan’s advice not to mention the
    cash . . . throughout his plea negotiations and entry.”
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 15 of 37
    19-14548               Opinion of the Court                      15
    The motion recounted that the government had contacted
    Hannan and asked him if he “had instructed Tywon to conceal ma-
    terial facts from the government.” As the government’s motion
    described it, Hannan denied doing so and his “version of his con-
    versations with Tywon is diametrically opposed to that of his cli-
    ent.”
    The court held a hearing on the government’s motion for
    clarification. At the hearing, the court talked with Tywon and Han-
    nan in chambers and outside the presence of the government and
    Moss. Tywon told the court about his and Hannan’s failed efforts
    to inform the government before the entry of the plea about the
    cash payments. He also told the court that when the prosecutors
    asked why he hadn’t brought it up sooner he told them: “Well, be-
    cause Mr. Hannan told me that when you asked me to bring it up.”
    Hannan confirmed Tywon’s statements were “substantially
    accurate,” confirmed he had not instructed Tywon to conceal the
    cash payments, and indicated what he’d told Tywon was that he
    “didn’t need to volunteer any information, just answer any ques-
    tions.” He also told the court that the cash payments had “been
    there all along” because they were “considered to be loans,” which
    is “in the Plea Agreement.” The court ruled that there was only
    miscommunication, not any misconduct, and that Hannan was not
    disqualified.
    Moss sought to call Hannan to testify at Moss’ trial, thinking
    that Hannan would contradict Tywon’s testimony. At trial, after
    Moss’ defense counsel examined Tywon in front of the jury and
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 16 of 37
    16                     Opinion of the Court               19-14548
    then briefly questioned Hannan outside the presence of the jury,
    the court quashed Moss’ subpoena of Hannan. It ruled that his tes-
    timony would have been about communications protected by the
    attorney-client privilege and that Tywon had not waived the privi-
    lege.
    2. Analysis
    Moss argues that the court erred in ruling that Tywon had
    not waived the attorney-client privilege and in quashing the sub-
    poena of Hannan on that basis. He also argues that the district
    court’s ruling violated his Fifth and Sixth Amendment rights to pre-
    sent a defense. The government responds that Moss failed to pre-
    serve the constitutional objection, meaning plain error review ap-
    plies, and that the court committed no error under any standard
    anyway. It also argues that any error was harmless.
    There are two things we need not decide. The first is
    whether Moss preserved his constitutional objection. Cf. Pon, 963
    F.3d at 1225–26 (discussing in dicta how not every contemporane-
    ous objection is a “constitutional objection” and that “[o]ur prece-
    dent indicates that an objection on nonconstitutional grounds is
    not enough to preserve a constitutional issue”) (quotation marks
    omitted). We need not decide that issue because Moss’ argument
    fails whether we apply de novo or plain error review.
    The second issue we need not decide is whether Tywon
    waived the attorney-client privilege. Even if he did and the court
    erroneously quashed the subpoena of Hannan in violation of Moss’
    USCA11 Case: 19-14548       Date Filed: 04/12/2022    Page: 17 of 37
    19-14548               Opinion of the Court                       17
    constitutional rights, any error was harmless beyond a reasonable
    doubt. See id. at 1226–27 (explaining that a “constitutional error is
    harmless if the government proves beyond a reasonable doubt that
    the error complained of did not contribute to the verdict obtained,”
    and satisfying that standard “necessarily means that any nonconsti-
    tutional error . . . was harmless as well”) (quotation marks omit-
    ted). The court’s ruling was harmless because Hannan’s testimony
    would not have helped Moss, and likely would have hurt him by
    corroborating Tywon’s testimony.
    Moss’ theory rests on a faulty foundation: that Hannan’s tes-
    timony could have been used to impeach Tywon. He bases that
    belief on the government’s motion seeking clarification of whether
    Hannan was disqualified. That motion stated that Hannan’s “ver-
    sion of his conversations with Tywon is diametrically opposed to
    that of his client.” But Moss fails to account for all the evidence,
    testimony, and clarification that came after that motion. And what
    he doesn’t account for indicates the opposite of what Moss as-
    serts — it shows that Hannan’s testimony would have corrobo-
    rated Tywon’s testimony, not impeached it.
    That Hannan would have corroborated Tywon’s testimony
    is evident both from the conversation the two of them had with
    the district court judge in chambers and from the questioning of
    each of them during the trial. In chambers, Tywon explained to
    the judge what had happened, including the fact that he had ini-
    tially told the government that he did not bring up the cash pay-
    ments sooner “because Mr. Hannan told me that when [the
    USCA11 Case: 19-14548             Date Filed: 04/12/2022         Page: 18 of 37
    18                          Opinion of the Court                        19-14548
    government] asked me[,] to [then] bring it up.” When asked if
    Tywon’s explanation was “substantially accurate” Hannan said
    “yes.” That’s agreement not disagreement, corroboration not con-
    tradiction.
    The consistency between Tywon’s and Hannan’s accounts
    of what happened was also evident in what took place in the court-
    room. Moss’ counsel cross-examined Tywon extensively in the
    presence of the jury about the cash payments and plea agreement.
    He asked Tywon if he had told the government that his “lawyer
    told [him] not to reveal the cash throughout the investigation, to
    the judge or to anyone.” Tywon responded unequivocally: “No.”
    That is the same answer attorney Hannan gave during the trial
    when Moss’ defense counsel asked him outside the presence of the
    jury whether he had told Moss to conceal the cash payments from
    the government.3
    After more cross-examination at trial, Tywon specified that
    what he’d told the government about the payments was: “My at-
    torney told me not to volunteer that until it was asked — or not to
    reveal that until I was asked.” That is also what Hannan had pre-
    viously told the court, before the trial, when he was questioned by
    the court in chambers. And when Moss’ counsel had a chance to
    question Hannan at the trial and outside the presence of the jury,
    3Hannan was not on the stand or under oath when he gave that answer. The
    district court explained that: “You are an officer of the Court. It is not required
    that you be put under oath.”
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 19 of 37
    19-14548               Opinion of the Court                      19
    counsel did not ask him whether he had simply given Tywon the
    generalized advice about not volunteering information. Had that
    question been asked of Hannan, as the government surely would
    have if he had testified before the jury, his in-chambers statement
    indicates that his answer would have been consistent with Tywon’s
    testimony.
    There is more evidence that Hannan would have corrobo-
    rated Tywon’s testimony that the cash payments were considered
    “loans,” which the plea agreement expressly mentioned. Tywon
    testified before the jury that Moss had told him the cash payments
    were actually loans and that Tywon did not have to claim them on
    his taxes because “the accountant has it worked out as a loan.” Ear-
    lier, during the in-chambers questioning, Hannan had told the
    judge that the cash payments had “been there all along” because
    the “money that [Tywon] was receiving in the form of cash was
    later considered to be loans,” so “it’s in the Plea Agreement.” Had
    he testified before the jury, Hannan would have corroborated
    Tywon’s testimony about the cash payments being loans.
    As a result, any erroneous exclusion of attorney Hannan’s
    testimony was harmless beyond a reasonable doubt. His testimony
    would not have impeached Tywon’s.
    B. Character Witnesses
    Moss contends that the district court erred in limiting how
    many character witnesses he could present to “rebut[] the
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 20 of 37
    20                     Opinion of the Court                19-14548
    government’s attempt to portray Dr. Moss as an uncaring, unsym-
    pathetic doctor, only concerned about money.”
    Moss was allowed to present six character witnesses: four
    former patients, one former patient’s wife, and one registered
    nurse who had worked with him in an emergency room. Those
    witnesses testified in detail about the medical care that Moss pro-
    vided, and they testified consistently that in their opinions he had
    a good character and was compassionate, caring, and honest. Their
    testimony covered a total of roughly 54 transcript pages. When
    Moss attempted to call even more character witnesses — he had as
    many as ten more he wanted to put on the stand — the court de-
    nied him permission because their testimony “would be cumula-
    tive.”
    Moss challenges that ruling. He argues that he needed more
    character witnesses to rebut the government’s portrayal of him be-
    cause “quantity is quality,” and it would be harder for the jury to
    dismiss opinions about Moss if “they were supported by patient,
    after patient, after patient.”
    It is well-established that district courts have considerable
    “discretion to limit the number of character witnesses” and that
    “we should overturn these determinations ‘rarely and only on a
    clear showing of prejudicial abuse of discretion.’” United States v.
    Benefield, 
    889 F.2d 1061
    , 1065 (11th Cir. 1989) (cleaned up)
    USCA11 Case: 19-14548           Date Filed: 04/12/2022         Page: 21 of 37
    19-14548                   Opinion of the Court                              21
    (quoting Michelson v. United States, 
    335 U.S. 469
    , 480 (1948)); see
    also Fed. R. Evid. 403.
    The discretion vested in the district courts has long been rec-
    ognized, originating at least a century ago in a decision of our pre-
    decessor Court. See, e.g., Chapa v. United States, 
    261 F. 775
    , 776
    (5th Cir. 1919) (affirming the district court’s decision to allow only
    13 of 150 tendered witnesses to testify that they had been cured by
    an occultist because “[i]t is discretionary with a trial court to limit
    the amount of cumulative evidence, and in this case it does not ap-
    pear that this discretion was abused”). 4 We have upheld a district
    court limiting a defendant to presenting only five of ten character
    witnesses, see Benefield, 
    889 F.2d at
    1065–66, and have several
    times upheld a limit of three, see, e,g., United States v. Gray, 
    507 F.2d 1013
    , 1015–16 (5th Cir. 1975). Those decisions and others like
    them establish that Moss has not made a “clear showing of preju-
    dicial abuse of discretion” in the district court’s limitation on his
    number of character witnesses. Benefield, 
    889 F.2d at 1065
     (quota-
    tion marks omitted).
    We add that Moss overstates the importance of character
    witness testimony in this case. The court prohibited the character
    witnesses from testifying to Moss’ billing practices, a ruling he does
    not challenge. And billing practices were what mattered given the

    661 F.2d 1206
    , 1209 (11th Cir. 1981) (en banc),
    we adopted as binding precedent all decisions of the former Fifth Circuit issued
    before October 1, 1981.

    22                     Opinion of the Court                19-14548
    charges. Moss was not on trial for being unkind or uncaring, or for
    not being compassionate when he did see patients, but for lying
    about seeing some patients at all and for billing Medicare for ser-
    vices he did not provide.
    C. Closing Argument
    Moss contends that the district court improperly limited part
    of his counsel’s closing argument when he was discussing whether
    Moss had made a profit. The government had argued that he was
    motivated by profit. And profit is relevant to motive, which is al-
    ways relevant in a criminal case. See United States v. Hill, 
    643 F.3d 807
    , 843 (11th Cir. 2011). But the argument of Moss’ counsel that
    the court limited was not about whether profit had motivated
    Moss. Instead, it was about whether the government had proven
    Moss’ medical practice made a profit. That argument would have
    misled the jury by treating profit as an element of the crime and
    the failure to prove profit as a basis for acquittal.
    Defense counsel began by discussing the expenses Moss had
    practicing medicine. He argued that the government had “brought
    you an FBI agent who spent all this time looking at the bank rec-
    ords. I don’t know what the math is in Washington, but Dr. Moss
    had all of the expenses.” After briefly discussing those expenses,
    counsel said: “And [the government is] saying [Moss] made a profit?
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 23 of 37
    19-14548               Opinion of the Court                      23
    There’s not one bit of proof. They have a duty to prove it beyond
    a reasonable doubt. They don’t prove it, you acquit.”
    A transcript paragraph later, Moss’ counsel went back to
    what the government had to prove, stating:
    So now, as you said, the judge will tell you we don’t
    have to prove anything because he’s presumed inno-
    cent. They failed to bring you any accounting that he
    made a dime. That he made a dollar. Or that he
    didn’t lose money. It’s vacant. But they stood up
    here and said it went into his bank account. Not into
    Shawn Tywon’s.
    At that point the court intervened. It stated that whether Moss
    “made a profit in his medical practice was not an issue in the case,
    and I think that’s an improper argument. And I so instruct the jury.
    Don’t argue that.”
    That ruling and that instruction were not error. It is one
    thing to argue that a defendant was not motivated by profit and
    another to argue that he didn’t commit a crime because there was
    no proof that he had netted a profit. No one, including criminals,
    is perfect. A person can be motivated to commit a crime by hope
    of profit, even though he does not succeed in turning one. The
    government does not have to prove a penny of profit to establish
    the elements of fraud. A paucity of proof of profit is no defense.
    Defense counsel was not entitled to argue that it was.
    IV. SENTENCE ISSUES
    USCA11 Case: 19-14548        Date Filed: 04/12/2022     Page: 24 of 37
    24                      Opinion of the Court                 19-14548
    Moss challenges the loss amount used to determine his sen-
    tence, the dollar amount he must pay in restitution, and how much
    he must forfeit.
    A. Intended Loss Amount
    Moss contends that his sentence should be vacated because
    the district court miscalculated the loss amount attributable to him,
    resulting in an offense level and a guidelines range that were higher
    than they should have been. An issue about the calculation of the
    guidelines range goes to the procedural reasonableness of the sen-
    tence. See United States v. Green, 
    981 F.3d 945
    , 953 (11th Cir.
    2020).
    The district court found that Moss was accountable for a loss
    amount of $6,031,046.70. That finding was based on an intended
    loss of $6,701,163. That was the amount Moss had billed to Medi-
    care, reduced by 10 percent, which was the court’s estimate of the
    value of the legitimate medical services he had provided. Moss at-
    tacks both the intended loss amount of $6.7 million which he thinks
    should be lower, and the 10 percent reduction which he thinks
    should be higher.
    “[W]e review the district court’s loss determination only for
    clear error.” United States v. Bazantes, 
    978 F.3d 1227
    , 1249 (11th
    Cir. 2020). Because “[d]istrict courts are in a unique position to
    evaluate the evidence relevant to a loss determination, . . . their de-
    terminations are entitled to appropriate deference.” United States
    v. Moran, 
    778 F.3d 942
    , 973 (11th Cir. 2015); accord U.S.S.G.
    USCA11 Case: 19-14548       Date Filed: 04/12/2022     Page: 25 of 37
    19-14548               Opinion of the Court                        25
    § 2B1.1 cmt. n.3(C). A district court need not make a precise deter-
    mination of loss amount, but only a reasonable estimate of it given
    the available information. Moran, 778 F.3d at 973. The estimate
    must be based on “reliable and specific” facts, and the court cannot
    “speculate about the existence of facts that would result in a higher
    sentence.” See id. Instead, it must make factual findings about the
    loss amount “based on evidence heard during trial, undisputed
    statements in the PSI, or evidence presented during sentencing.”
    Id.
    As for the intended loss amount attributed to Moss, the
    court followed U.S.S.G. § 2B1.1 and its commentary about in-
    tended loss. That commentary is “binding on the courts” because
    it does not “contradict the plain meaning of the text of the Guide-
    lines.” See United States v. Wilks, 
    464 F.3d 1240
    , 1245 (11th Cir.
    2006) (quotation marks omitted). It specifies that “loss is the
    greater of actual loss or intended loss.” U.S.S.G. § 2B1.1 cmt.
    n.3(A). And it also specifies that “[i]ntended loss” is “the pecuniary
    harm that the defendant purposely sought to inflict,” including “pe-
    cuniary harm that would have been impossible or unlikely to oc-
    cur.” Id. at cmt. n.3(A)(ii). One example the commentary gives of
    unlikely harm that should be included is “an insurance fraud in
    which the claim exceeded the insured value.” Id.
    And when it comes to “federal health care offenses involving
    government health care programs,” § 2B1.1’s commentary pro-
    vides a rebuttable presumption that the intended loss equals the
    amount the defendant billed a government agency. Id. at cmt.
    USCA11 Case: 19-14548       Date Filed: 04/12/2022     Page: 26 of 37
    26                     Opinion of the Court                 19-14548
    n.3(F)(viii) (emphasis and capitalization omitted). The commen-
    tary puts it this way: “[T]he aggregate dollar amount of fraudulent
    bills submitted to the Government health care program shall con-
    stitute prima facie evidence of the amount of the intended loss, i.e.,
    is evidence sufficient to establish the amount of the intended loss,
    if not rebutted.” Id.
    Moss contends that presumption was rebutted because the
    evidence showed he was highly knowledgeable about Medicare’s
    reimbursement policies. He argues that evidence establishes he
    knew Medicare would not pay more than what is in its reimburse-
    ment schedules, regardless of how high he overbilled. Moss’ argu-
    ment actually goes further than that. He argues he knew Medi-
    care’s reimbursement schedules so well that he knew exactly how
    much he’d get: the roughly $2.5 million that Medicare ended up
    paying him. And since he knew that Medicare would pay only $2.5
    million, he argues, that was the amount he intended to receive, and
    no more than that.
    We will assume that Moss’ knowledge of Medicare’s reim-
    bursement policies and schedules is enough to rebut the presump-
    tion in § 2B1.1’s commentary that the intended loss was the
    amount he billed Medicare. Even assuming that, the district court
    still did not clearly err in finding that Moss’ intended loss is $6.7
    million, not $2.5 million.
    After all, intended loss is “pecuniary harm that the defendant
    purposely sought to inflict” and also “includes intended pecuniary
    harm that would have been impossible or unlikely to occur.”
    USCA11 Case: 19-14548       Date Filed: 04/12/2022    Page: 27 of 37
    19-14548               Opinion of the Court                       27
    U.S.S.G. § 2B1.1 cmt. n.3(A)(ii) (emphasis added). The plain mean-
    ing of that definition is confirmed by the commentary’s insurance
    fraud example we mentioned. Id. What makes it unlikely the ac-
    tual loss will be as high as the full amount of the fraudulent insur-
    ance claim is that the claim exceeds the insured value, and insur-
    ance companies rarely if ever slip up and pay the excessive amount.
    The hypothetical defendant in that commentary example knew it
    was “unlikely” the claim would be paid in full, but he submitted
    the full amount anyway with the greedy hope that he would mis-
    takenly be paid the full amount.
    That commentary example is similar to what Moss did. He
    intentionally billed in a way that would maximize the money he
    received from Medicare. As the district court put it: “[W]hile
    [Moss] may not have expected that Medicare . . . would reimburse
    him at a rate of 100 percent, it is apparent that he manipulated his
    billings to maximize his profits. The Court finds this evidence cred-
    ible.” The way Moss “maximized” his profits was by always billing
    his claims at a rate higher than the one in Medicare’s schedules.
    That matters because Medicare pays either the billed amount or
    the scheduled amount, whichever one is lower. If the schedule says
    $100 and the physician’s claim says $60, Medicare will pay $60. But
    if the schedule says $100 and the physician’s claim says $120, Med-
    icare will pay $100. By billing more than the scheduled amount,
    Moss ensured that he always got the full amount Medicare would
    pay.
    USCA11 Case: 19-14548      Date Filed: 04/12/2022   Page: 28 of 37
    28                    Opinion of the Court               19-14548
    That’s not the only way that overshooting the payment
    schedules profited him. Medicare adjusts those schedules at least
    annually. By billing well over the scheduled amount, Moss may
    have been able to capture rate increases up to his billed amount.
    His own argument is that he knew Medicare’s reimbursement pol-
    icies exceptionally well. It follows that he would have known
    about Medicare periodically adjusting its payment schedules. He
    would have known how inflating the amount of each bill would
    get him the maximum possible payments from Medicare and the
    full benefit from any of its schedule increases.
    It was unlikely that Medicare’s rates would have increased
    all the way up to the amount Moss billed, or that Medicare would
    have mistakenly paid him the full billed amount. But Moss tried.
    As we’ve said several times now, intended loss includes even loss
    and harm that is unlikely to occur. The factfindings made by the
    district court show that Moss’ actions fall within § 2B1.1’s com-
    mentary and its example. Our review of the intended loss amount
    is only for clear error, and there is none.
    B. Restitution
    Moss contends that the $2,256,861.32 the district court or-
    dered him to pay in restitution is too much. The court added the
    amounts that Medicare and Medicaid had paid him for claims
    billed under CPT codes 99306, 99309, and 99310, which came to a
    total of $2,507,623.69. It reduced that amount by $250,762.37,
    based on the court’s estimate that 10 percent of the services Moss
    provided had been legitimate.
    USCA11 Case: 19-14548           Date Filed: 04/12/2022        Page: 29 of 37
    19-14548                  Opinion of the Court                              29
    Moss claims that he is entitled to more than a 10 percent re-
    duction for legitimate services. He claims that the 10 percent re-
    duction is based on nothing but a single line of testimony from
    Tywon: his statement that when he visited patients “probably for
    95 percent of the time or more, there was nothing to do,” meaning
    that 95 percent of the time the visits were not medically necessary.
    (The court apparently doubled the percentage of medically neces-
    sary visits from Tywon’s testimony, which was to Moss’ benefit.)
    Instead of relying on Tywon’s testimony, Moss says, the court
    should have used an estimate he provided in a sentencing memo-
    randum and presented at the sentence hearing. Moss’ estimate was
    that the value of legitimate services was $1,079,219.39, which
    would reduce restitution to $1,428,404.30. 5
    We review de novo the legality of a restitution order, but
    only for clear error the factual findings underpinning the order.
    United States v. Edwards,

    5 The loss amount that determines Moss’ offense level is also reduced for le-
    gitimate services rendered. See U.S.S.G. § 2B1.1 cmt. n.3(E)(i). Moss received
    an increase of 18 levels because the loss amount was between $3.5 and $9.5
    million. See U.S.S.G. § 2B1.1(b)(1). We have already held that the proper
    starting point for calculating Moss’ loss amount is an intended loss of roughly
    $6.7 million. Supra at 29. Even if we subtract from that figure the total
    amount of legitimate services Moss argues he provided, it would not take the
    loss amount below $3.5 million, so it would not affect his guidelines range.
    Any error would be harmless. See United States v. Sarras,

    left with the definite and firm conviction that a mistake has been
    committed.” United States v. Alicea, 
    875 F.3d 606
    , 608 (11th Cir.
    2017) (quotation marks omitted).
    “Under 18 U.S.C. § 3663A(c), [the Mandatory Victims Resti-
    tution Act,] a defendant convicted of fraud must pay restitution to
    victims of the offense.” United States v. Bane, 
    720 F.3d 818
    , 827
    (11th Cir. 2013). Restitution “must be based on the amount of loss
    actually caused by the defendant’s conduct,” United States v. Bald-
    win, 
    774 F.3d 711
    , 728 (11th Cir. 2014), and reduced by the value of
    legitimate medical services provided, see Bane, 720 F.3d at 828.
    Moss “bears the burden to prove the value of any medically neces-
    sary goods or services he provided that he claims should not be in-
    cluded in the restitution amount.” Id. at 829 n.10.
    When calculating the restitution amount, “the determina-
    tion . . . is by nature an inexact science, [and] where difficulties
    arise, a district court may accept a ‘reasonable estimate’ of the loss
    based on the evidence presented.” Baldwin, 774 F.3d at 728 (cita-
    tion omitted). Difficulties have certainly arisen here. There is no
    “definite and easy” way to calculate restitution with “a simple
    mathematical exercise.” United States v. Sheffield, 
    939 F.3d 1274
    ,
    1277–78 (11th Cir. 2019). Although there is a record of how much
    Medicare and Medicaid paid to Moss and that number is exact, the
    dollar amount of legitimate services is anything but exact. The
    only thing anyone can do is estimate.
    That includes Moss, who, as mentioned, provided the dis-
    trict court with an estimate of legitimate services. He provided the
    USCA11 Case: 19-14548        Date Filed: 04/12/2022      Page: 31 of 37
    19-14548                Opinion of the Court                         31
    estimate in a sentencing memorandum that explained the method-
    ology behind it, and he also called as a witness at the sentence hear-
    ing the medical practice consultant who had helped prepare Moss’
    estimate.
    After the court reviewed the sentencing memorandum, lis-
    tened to extensive direct and cross-examination of Moss’ medical
    practice consultant witness, asked that witness additional ques-
    tions, and heard argument from and questioned the attorneys, the
    court rejected Moss’ estimate. The court primarily pointed out a
    problem with Moss’ methodology. It noted that he had presented
    evidence that patients had been visited, but not that the visits were
    medically necessary in the first place. The court put it like this:
    “While presenting evidence as to the number of visits performed,
    [Moss] has failed to present evidence establishing the legitimacy of
    those visits. It is of no consequence that Mr. Tywon may have seen
    an average of 4.5 rehab patients a day when Mr. Tywon has testi-
    fied that 95 percent of those services were fraudulent.”
    We have carefully reviewed Moss’ estimate and conclude
    that the district court did not clearly err in rejecting it and in iden-
    tifying the fatal defect in his methodology we just discussed. The
    burden was on Moss to show that the services he provided were
    medically necessary. See Bane, 720 F.3d at 829 n.10. When services
    are not medically necessary, Medicare reimburses at a rate of $0.
    Because of that, it does not matter how many medically unneces-
    sary visits Moss and his employees may have made to patients,
    which was the basis of Moss’ estimate. Zero times a thousand is

    32                      Opinion of the Court                  19-14548
    still zero. Because Moss’ estimate failed to embrace, salute, or even
    nod at medical necessity, the district court did not clearly err in giv-
    ing it little or no value.
    As for the district court’s estimate of 10 percent, it was not
    clearly erroneous and there was evidence supporting it. One major
    piece of evidence was Tywon’s testimony. He estimated that only
    five percent of the time when he visited patients was there anything
    to do. The court’s findings about legitimate services expressly re-
    lied on Tywon’s testimony, indicating that it found him credible.
    We defer to the court’s credibility determinations. See United
    States v. Ramirez-Chilel, 
    289 F.3d 744
    , 749 (11th Cir. 2002). (As
    we’ve mentioned, just to be safe the court doubled in Moss’ favor
    Tywon’s estimated percentage of legitimacy, which is not some-
    thing Moss can complain about.) Additionally, Tywon’s testimony
    was supported by the notes that documented his patient visits,
    which were mostly copy-pasted from one to the next and rarely
    reflected any changed medical conditions.
    Our review of Moss’ estimate and the court’s reasons for re-
    jecting it does not leave us with a firm and definite conviction that
    the court made a mistake. The court committed no clear error in
    rejecting Moss’ estimate and in ordering restitution in the amount
    of $2,256,861.32.
    C. Forfeiture
    The district court ordered Moss to forfeit $2,507,623.69.
    That is the total that Medicare and Medicaid paid him for claims
    USCA11 Case: 19-14548        Date Filed: 04/12/2022     Page: 33 of 37
    19-14548                Opinion of the Court                        33
    billed under CPT codes 99306, 99309, and 99310. Unlike with the
    restitution amount, the court did not reduce the forfeiture amount
    by 10 percent for legitimate services. Nor, for that matter, did it
    reduce the forfeiture amount by any estimate for legitimate ser-
    vices. Moss contends that was error. He argues that the forfeiture
    amount must be reduced by the amount of legitimate services he
    provided. The issue turns in part on statutory interpretation and
    in part on a factual determination.
    “In reviewing forfeiture orders, we review findings of fact
    for clear error and legal conclusions de novo.” United States v.
    Goldstein, 
    989 F.3d 1178
    , 1202 (11th Cir. 2021). We review de novo
    questions of statutory interpretation. United States v. Segarra, 
    582 F.3d 1269
    , 1271 (11th Cir. 2009).
    An important preliminary point is that just because the loss
    and restitution amounts were reduced by 10 percent does not nec-
    essarily mean the forfeiture amount must be. “[R]estitution and
    forfeiture serve different goals. The focus of restitution is on the
    victim, but forfeiture focuses on the defendant.” United States v.
    Hoffman-Vaile, 
    568 F.3d 1335
    , 1344 (11th Cir. 2009) (citation and
    quotation marks omitted and alterations adopted). Unlike restitu-
    tion, “forfeiture is also a punitive action against the defendant.” 
    Id.
    at 1344–45 (quotation marks omitted). In addition to those differ-
    ent purposes, the forfeiture order in this case was required by dif-
    ferent and broader statutory text than the restitution order. That
    text is our focus.
    USCA11 Case: 19-14548       Date Filed: 04/12/2022     Page: 34 of 37
    34                     Opinion of the Court                 19-14548
    Forfeiture was ordered under 
    18 U.S.C. § 982
    (a)(7), which
    provides that, in convictions for federal health care offenses like
    Moss’, the court “shall order the person to forfeit property, real or
    personal, that constitutes or is derived, directly or indirectly, from
    gross proceeds traceable to the commission of the offense.” The
    question is whether that text encompasses the proceeds Moss’ re-
    ceived for providing legitimate services. The key to answering the
    question is determining what makes proceeds “gross proceeds
    traceable to the commission of the offense.”
    Our precedent tells us how to make that determination. We
    have effectively defined § 982(a)(7)’s use of the words “gross pro-
    ceeds traceable” to impose a “but for” standard. See Hoffman-
    Vaile, 
    568 F.3d at 1344
    . We did so in holding that a defendant who
    had been reimbursed by Medicare as well as private parties had to
    forfeit the amounts received from both Medicare and the private
    parties. 
    Id.
     We concluded that the amounts the defendant “re-
    ceived from private insurance companies [were] ‘gross proceeds
    traceable to the commission of’ her fraud because, but for her Med-
    icare fraud, she would not have been entitled to collect these
    sums.” 
    Id.
     (emphasis added).
    The D.C. Circuit has used similar “but for” reasoning when
    deciding whether forfeiture ordered under § 982(a)(7) excludes le-
    gitimate services from proceeds. See United States v. Bikundi, 
    926 F.3d 761
     (D.C. Cir. 2019). It held “no” in a case where the money
    obtained from the fraud had propped up the defendants’ legitimate
    services. See id. at 793. As the district court had found, the fraud
    USCA11 Case: 19-14548        Date Filed: 04/12/2022      Page: 35 of 37
    19-14548                Opinion of the Court                         35
    was pervasive and the defendant’s operations could not have con-
    tinued at all without it. Id. Part of its findings were that the de-
    fendants’ company “would not have operated but for [each] de-
    fendant’s fraud” and that the total amount of Medicaid proceeds
    received “was only paid due to the defendants’ persistent and ram-
    pant fraudulent conduct.” Id. (quotation marks omitted; alteration
    and emphasis in original). “Because the pervasive fraud was inte-
    gral to each and every Medicaid payment to” the defendants, all of
    the payments were properly considered as being “constitute[d]” or
    “‘derived, directly or indirectly’ from ‘gross proceeds traceable’” to
    the fraud. Id. (quoting 
    18 U.S.C. § 982
    (a)(7)) (alteration in original).
    That statutory interpretation points us toward using a but
    for test, which leaves this factual determination: but for his Medi-
    care fraud, would Moss have been entitled to collect proceeds for
    his legitimate services? See Hoffman-Vaile, 
    568 F.3d at 1344
    ;
    Bikundi, 926 F.3d at 793. “But for” means that if one thing hadn’t
    happened another thing would not have happened. “In other
    words, a but-for test directs us to change one thing at a time and
    see if the outcome changes. If it does, we have found a but-for
    cause.” Bostock v. Clayton Cnty., Ga., 
    140 S. Ct. 1731
    , 1739 (2020).
    So we ask if Moss had not committed fraud, would he have been
    entitled to any proceeds for his legitimate services?
    As an illustration, consider a hypothetical where a doctor
    submits three claims. Claims one and two involve some legitimate
    services but are fraudulent because they are improperly billed
    while claim three is legitimate and properly billed, not fraudulent.
    USCA11 Case: 19-14548            Date Filed: 04/12/2022         Page: 36 of 37
    36                         Opinion of the Court                       19-14548
    Take away the fraud — which is claims one and two — and claim
    three would still be for legitimate proceeds that the doctor would
    be entitled to be paid for even without the fraudulent claims. 6
    Compare and contrast that with Moss. As in the hypothet-
    ical, Moss’ fraud was his improper billing of claims. But take away
    the fraudulent billing and what’s left? The record does not reveal
    any of Moss’ claims that were both for legitimate services and
    properly billed — no “claim three” category claims were shown.
    Not a single one. As far as the record shows, it’s all fraudulent bill-
    ing. During both the sentence proceedings and this appeal Moss
    has not identified one specific claim in the record that was properly
    billed.
    Here’s the thing. It is not enough that Moss and his employ-
    ees may have provided some underlying legitimate services but
    overbilled for them. That’s not enough because Medicare values
    an improperly billed claim at $0, regardless of what amount of un-
    derlying legitimate services might have been provided and could
    have been reimbursed if there hadn’t been any improper billing.
    6 There may still be reasons that claim three in that hypothetical would fail the
    but-for test. One reason would be a Bikundi scenario, where the legitimate
    services were being so heavily propped up by money from the fraud that they
    could not exist without it. See Bikundi, 926 F.3d at 793 (holding there should
    be no reduction in the forfeiture amount based on legitimate services where
    the district court had found that the defendant’s “continuing operations were
    maintained based on fraudulent records in employee and patient files and
    fraudulent timesheets submitted for reimbursement”).
    USCA11 Case: 19-14548      Date Filed: 04/12/2022     Page: 37 of 37
    19-14548               Opinion of the Court                      37
    For example, if a medical service was performed by a physician’s
    assistant and could properly have been billed at $75, but was im-
    properly billed at the physician’s rate of $100, Medicare would not
    value that claim at, or pay, $75. Instead, Medicare would value the
    claim at, and pay, $0 because it was improperly billed. Had Medi-
    care known of Moss’ improper billing, it would not have paid him
    some discounted rate — it would have paid him nothing. The
    gross proceeds from an improperly billed claim are all traceable to
    the improper billing, even the portion of proceeds that could have
    been paid for legitimate services if they had been properly billed.
    Because the question of whether the record shows any of
    Moss’ claims were properly billed is a factual one, we review only
    for clear error the district court’s implicit finding that none were
    properly billed. See Goldstein, 989 F.3d at 1202. Given Moss’ fail-
    ure to identify a single properly billed claim, he has not persuaded
    us that the district court clearly erred.
    AFFIRMED.
