    Appeals from the United States District Court
    for the Southern District of Texas
    Before DENNIS, CLEMENT, and SOUTHWICK, Circuit Judges.
    LESLIE H. SOUTHWICK, Circuit Judge:
    The defendants were convicted on numerous counts related to their
    involvement in schemes to commit health care fraud, receive or pay healthcare
    kickbacks, and/or make false statements for use in determining rights for benefit
    and payment by Medicare. Caroline Njoku, Terrie Porter, and Mary Ellis appeal
    their convictions on grounds of insufficient evidence. Njoku also argues the
    sentences she received on two counts were multiplicitous and the oral
    pronouncement of her sentence conflicts with the written judgment. Ellis
    contends that she was twice put in jeopardy because of a previous acquittal and
    that collateral estoppel bars the relitigation of certain issues. Ellis further
    brings an evidentiary challenge involving rules of hearsay and relevancy, as well

    her right to present a defense. Ellis also argues her sentence resulted from an
    improper enhancement. Ezinne Ubani appeals her sentence based on the
    application of two enhancement provisions.
    We REMAND for the district court to amend Njoku’s written judgment to
    conform to her oral sentence. We AFFIRM in all other respects.
    BACKGROUND
    On October 7, 2010, Njoku, Porter, Ellis, Ubani, and other co-defendants
    who are not parties in this appeal were indicted in the United States District
    Court for the Southern District of Texas. Njoku, Ellis, and Ubani were each
    charged with one count of conspiracy to commit health care fraud under 18
    U.S.C. § 1349. Njoku, Porter, and Ellis were each charged with one count of
    conspiracy to receive or pay health care kickbacks under 18 U.S.C. § 371. Njoku
    and Porter were charged on one count and Ellis on three counts of receipt or
    payment of kickbacks in violation of 42 U.S.C. § 1320a-7b(b) and 18 U.S.C. § 2.
    Ellis and Ubani were charged with two counts each of making false statements
    for use in determining rights for benefit and payment by Medicare under 42
    U.S.C. § 1320a-7b(a)(2) and 18 U.S.C. § 2.
    There was evidence that articles of incorporation were filed on November
    1, 2004 for a company named Family Healthcare Group, Inc., which would do
    business in Houston, Texas. The document listed Clifford Ubani, Princewill
    Njoku, and Ezinne Ubani as directors.1 The company submitted a Medicare

    provider application in May 2005, which was approved in early 2006. The
    document listed Clifford Ubani and Princewill Njoku as co-owners; Ezinne Ubani
    was listed as a director/officer.
    An authorized Medicare provider may bill Medicare for covered services
    provided to eligible beneficiaries. Family Healthcare provided home health care
    to individuals by use of skilled nurses. To qualify for such services under
    Medicare regulations, the patient must be homebound, under a doctor’s care, and
    require skilled nursing. A claims analyst who reviewed medical records for
    Medicare fraud testified that “homebound” meant that it was generally taxing
    for the patient to leave home. In the analyst’s nine years of experience, the
    referral source for such care was the patient’s primary care physician.
    The analyst further explained that in order to initiate such care, a
    registered nurse (“RN”) was required to meet with the patient and complete an
    Outcome Assessment Information Set (“OASIS”). The questionnaire helped
    identify the patient’s ability to function in daily living and would be used in part
    to determine whether the patient was homebound. Information from the OASIS
    would be entered into a computer program, which would produce a “plan of
    care.” The same nurse who completed the OASIS was required to sign the plan
    of care. The plan would then be submitted to the referring physician to certify
    and sign.
    If approved by the physician, a period of care lasted 60 days for purposes
    of Medicare regulations. A licensed vocational nurse (“LVN”) provided the
    skilled nursing in the patient’s home. The law required LVNs to keep nursing
    notes to document their visits and prove the care given. Additionally, these
    Princewill Njoku are referenced throughout this opinion using their first and last names.

    notes could provide a log of medication and patient conditions for future use.
    Agent Harshaw, a special agent charged with the investigation of criminal
    violations of the health care fraud laws, testified that Medicare required the
    nursing notes be preserved for auditing purposes.
    The analyst explained that such services were not intended to be
    continuous. Nurses would instruct the patient or a caregiver on how to provide
    the needed care without a nurse’s assistance. If a patient continued to need
    skilled nursing after the initial period, recertification for 60 more days was
    available. During the last five days of the first period, an RN would be required
    to visit and reassess the patient. This recertification process required the
    completion of a second, condensed OASIS. Agent Harshaw testified that an RN
    would partly rely on the LVN’s nursing notes to complete the recertification
    evaluation. Adelma Sevilla, an RN who worked for Family Healthcare, testified
    that she reviewed nursing notes during this process. Once the recertification
    OASIS was complete, a new plan of care would be prepared, signed by the RN,
    and submitted to a physician for signed approval. The physician’s approval
    generally involved the physician personally visiting the patient.
    Medicare would reimburse service providers in bifurcated installments.
    The first was a payment of 60 percent of the claim after the initial billing.
    Medicare did not necessarily receive a patient’s OASIS or plan of care at that
    time but instead relied on the service provider’s representation subject to future
    inspections via audit. The remaining portion of the claim was paid once a
    sufficient number of skilled nursing visits were made. The indictment stated
    that Family Healthcare was paid approximately $5.2 million for home health

    care services between April 2006 and August 2009. We describe in more detail
    below each individual’s role. For now, we provide a general overview.
    Njoku and Ellis worked as LVNs who provided skilled nursing care to
    patients. Ellis also referred Medicare beneficiaries to Family Healthcare. Porter
    also referred Medicare beneficiaries. Ubani worked as an RN who completed
    OASIS questionnaires and signed plans of care. At times, Family Healthcare
    used specific physicians to certify the plans of care.
    Evidence at trial showed that Family Healthcare billed Medicare for
    services to beneficiaries who were ineligible for home health care because they
    were either not homebound or not in need of skilled nursing. RNs would sign
    OASIS questionnaires both on initial assessments and during recertifications
    without visiting the patients. Skilled nursing services were allegedly inadequate
    and misrepresented in the documented nursing notes. At least one physician
    was paid to authorize plans of care despite not having examined the patients.
    Recruiters were paid kickbacks to refer Medicare beneficiaries in order to
    accumulate additional patients.
    After an eleven day trial, the jury found Njoku, Ellis, and Ubani guilty of
    conspiracy to commit health care fraud in Count 1. Njoku, Porter, and Ellis
    were found guilty of conspiracy to receive or pay health care kickbacks in Count
    2.   The jury found Njoku not guilty of receipt or payment of health care
    kickbacks in Count 12. Porter was found guilty of receipt or payment of health
    care kickbacks in Count 17. Ellis was found guilty of receipt or payment of
    health care kickbacks in Counts 3, 4, and 5. Finally, the jury found Ellis and
    Ubani guilty of making false statements for use in determining rights for benefit
    and payment by Medicare in Counts 20 and 21.

    The district court announced Njoku’s sentence as 63 months on Count 1
    and 60 months on Count 2, to run concurrently.2 Porter was sentenced to 24
    months on Counts 2 and 17 to run concurrently. The court sentenced Ellis to 63
    months on Count 1 and 60 months on Counts 2, 3, 4, 5, 20, and 21 to run
    concurrently. Ubani was sentenced to 97 months on Count 1 and 60 months on
    Counts 20 and 21 to run concurrently. These defendants appealed.
    DISCUSSION
    Njoku, Ellis, and Porter challenge the sufficiency of the evidence on some
    of the counts. Njoku, Ellis, and Ubani raise arguments as to their sentences.
    Ellis raises a variety of other issues. We address each issue in turn.
    A. Sufficiency of the Evidence
    We review the defendants’ “preserved challenges to the sufficiency of the
    evidence de novo.” United States v. Grant, 
    683 F.3d 639
    , 642 (5th Cir. 2012). We
    view both circumstantial and direct evidence “in the light most favorable to the
    government, with all reasonable inferences and credibility choices to be made in
    support of the jury’s verdict.” 
    Id. In doing
    so, we ask “whether a rational trier
    of fact could have found the essential elements of the crime beyond a reasonable
    doubt.” 
    Id. (quotation marks
    omitted).
    1. Count 1 (Conspiracy to Commit Health Care Fraud)
    A conspiracy to commit health care fraud under 18 U.S.C. § 1347 requires
    that the fraud be the object of the conspiracy.           18 U.S.C. § 1349.       The
    2
    The written judgment states that Njoku was sentenced to 63 months’ imprisonment
    on both counts. We address this issue below.
    6
    Case: 12-20095    Document: 00512456949     Page: 7   Date Filed: 12/02/2013
    No. 12-20095
    conspirators must “knowingly and willfully” execute a scheme “to defraud any
    healthcare benefit program” or “to obtain, [through false pretenses] any of the
    money or property owned by . . . any health care benefit program.” 18 U.S.C.
    § 1347. Conviction requires proof “that (1) two or more persons made an
    agreement to commit health care fraud; (2) that the defendant knew the
    unlawful purpose of the agreement; and (3) that the defendant joined in the
    agreement willfully, that is, with the intent to further the unlawful purpose.”
    
    Grant, 683 F.3d at 643
    . Circumstantial evidence can prove knowledge and
    participation. 
    Id. In her
    motion for judgment of acquittal and on appeal, Njoku argues the
    evidence was insufficient to prove she knew of the unlawful purpose and joined
    the agreement willfully. We find sufficiency from the following.
    Adelma Sevilla testified that she worked for Family Healthcare as an RN.
    She admitted to falsifying forms submitted to Medicare and said that other
    people she worked with, including Njoku, participated. Because Sevilla could
    not drive a vehicle, Njoku almost always drove her to patients’ homes to perform
    assessments. Njoku was also present with Sevilla during those assessments and
    witnessed patients performing activities that belied their homebound status or
    need for skilled nursing. One patient who walked around without assistance
    directly told Njoku that he could drive himself. Sevilla confirmed that she
    falsified the OASIS for this patient and for others. Njoku was hardly oblivious
    to the requirements. She not only worked as an LVN for Family Healthcare but
    also had completed training on OASIS assessments and reporting.
    Even though Sevilla at one point expressed concern that some patients
    were not homebound, Njoku responded that Sevilla should process the
    7
    Case: 12-20095     Document: 00512456949      Page: 8   Date Filed: 12/02/2013
    No. 12-20095
    admissions anyway. Princewill Njoku was also an RN. After he was indicted,
    Caroline Njoku asked Sevilla, another RN, to sign recertification assessments
    in Princewill Njoku’s place. Despite not having visited any of the patients,
    Sevilla complied. It is reasonable to infer that Caroline Njoku knew Sevilla had
    not completed in-person assessments of these patients partly because Njoku
    usually drove Sevilla to each patient’s home. There were also times when plans
    of care were returned from physicians without their approval, and Njoku
    instructed office clerks to send the forms to a Dr. Echols, who was later shown
    to be involved in the scheme.
    The underlying scheme was to obtain money from Medicare by false
    pretenses. We conclude there was sufficient evidence of Njoku’s knowledge of
    the agreement and her willful joining of it with the intent to further its purpose.
    2. Count 2 (Conspiracy to Receive or Pay Health Care Kickbacks)
    It is unlawful to conspire with another to commit an offense against the
    United States and do an act to effect the conspiracy’s object. 18 U.S.C. § 371.
    The substantive offenses in this case were the knowing and willful receipt of a
    remuneration, namely, a kickback, in return for referring a patient for home
    healthcare, or payment of such remuneration in order to induce someone to
    make such a reference. See 42 U.S.C. § 1320a-7b(b). A conviction of conspiracy
    under Section 371 requires the Government to prove:
    (1) an agreement between two or more persons to pursue an
    unlawful objective; (2) the defendant’s knowledge of the unlawful
    objective and voluntary agreement to join the conspiracy; and (3) an
    overt act by one or more of the members of the conspiracy in
    furtherance of the objective of the conspiracy.

    “The government must prove the same degree of criminal intent as is
    necessary for proof of the underlying substantive offense.” United States v.
    Peterson, 
    244 F.3d 385
    , 389 (5th Cir. 2001). Thus, in addition to proving an
    intent to further the unlawful objective, there must also be proof that the
    defendant acted willfully, that is, “with the specific intent to do something the
    law forbids.” United States v. Garcia, 
    762 F.2d 1222
    , 1224 (5th Cir. 1985); see
    also United States v. Davis, 
    132 F.3d 1092
    , 1094 (5th Cir. 1998).
    a. Caroline Njoku
    Njoku argues the evidence was insufficient to prove she knew of the
    unlawful purpose and joined the agreement with the intent to further that
    objective.3 She contends the evidence shows mere presence in a climate of
    unlawful activity. We disagree.
    Sammie Wilson testified that she received payments through checks
    drawn on Family Healthcare’s account in exchange for referring patients who
    were Medicare beneficiaries. Wilson explained that notations on the checks such
    as “for 4” meant the number of patients she referred. At times, she was paid
    $500 per patient. On at least one occasion, Princewill Njoku was in the driver’s
    seat of a vehicle and his then-wife Caroline was a passenger. He reached across
    Caroline and gave a check to Wilson as payment for patients she had referred.
    There also was evidence of a check dated November 10, 2008, made
    payable to Caroline Njoku and drawn on Family Healthcare’s account in the
    amount of $2,500. The memo line showed “5 from Sammie Wilson.” There was
    3
    In her argument on appeal, Njoku also relies on the fact jurors found her not guilty
    on Count 12 – a charge for a substantive offense under 42 U.S.C. § 1320a-7b(b) – and that such
    acquittal supports the inadequacy of the evidence on Count 2. Not so, as our “review is to be
    independent of the jury’s determination that evidence on another count was insufficient.”
    United States v. Montalvo, 
    820 F.2d 686
    , 690 (5th Cir. 1987) (quotation marks omitted).
    9

    a computerized notation on the check revealing it had been cashed. Njoku does
    not deny receiving the check and, in fact, attempted through cross examination
    to show that the check was her part of that month’s payroll. Testimony from
    Ana Quinteros, a certified nursing assistant who worked for Family Healthcare,
    showed that some recruiters were paid in cash and were also paid through other
    people. Wilson did testify that she never received cash payments.
    Regardless, Wilson’s denial of cash payments would not mean the evidence
    was insufficient for the jury to find Njoku guilty of conspiracy. We must draw
    all reasonable inferences in favor of the jury’s verdict. 
    Grant, 683 F.3d at 642
    .
    Wilson’s testimony revealed that she and Njoku had a uniquely close
    relationship, more than a typical nurse-patient friendship. Wilson actively
    worked as a recruiter for Family Healthcare, and it is reasonable to infer that
    Njoku knew Wilson was being paid for those referrals as part of the underlying
    scheme. Further, Njoku’s activities, including her involvement with what one
    could infer was a payment to Wilson, are sufficient to prove Njoku willfully
    joined in the agreement to pay recruiters for referrals.
    b. Terrie Porter
    Porter, who was one of the alleged recruiters for Family Healthcare,
    argues the evidence was insufficient to prove she knew about an unlawful
    objective or joined the agreement with the intent to further that objective.
    Porter contends she referred patients to Family Healthcare because she believed
    they needed and would receive home health care. Porter states she had no
    agreement to recruit only Medicare beneficiaries.
    Between 2006 and 2009, Porter worked at the University of Texas Health
    Science Center in the Department of Physical Medicine and Rehabilitation. She
    10
    Case: 12-20095     Document: 00512456949      Page: 11   Date Filed: 12/02/2013
    No. 12-20095
    assisted physicians in administrative responsibilities. Her resume revealed that
    she worked with confidential patient information. Porter testified, though, that
    the only patient billing she handled was for compensation claims for work-
    related injuries and not claims involving Medicare. She explicitly denied having
    access to patients’ Medicare information.
    Porter testified that her friend believed a nearby agency (Family
    Healthcare) was looking for community liaisons. She was put in touch with
    Clifford Ubani and eventually interviewed with him and Princewill Njoku in a
    vehicle outside of her place of employment. She wondered whether the two men
    were involved in a fraud. Porter later admitted at trial that Family Healthcare
    began paying her for referring patients. Agents eventually discovered a log of
    Porter’s referrals on the computer hard drives at Family Healthcare. Although
    Porter argues she was not listed as the referral source for corresponding patients
    on other documents, the jury heard testimony from Agent Harshaw that it was
    permissible to have more than one referral source per patient.
    Porter’s main defense was that she did not know about the Family
    Healthcare’s schemes or the illegality of the referral payments. She denied
    having an agreement with Clifford Ubani to receive payments only for Medicare-
    beneficiary referrals. Porter alleged he paid her for anyone she referred.
    There was testimony that Memorial Hermann Hospital was a teaching
    institution for the University of Texas in Houston. Hermann Hospital provided
    patient information to the University for billing purposes. Dr. Stephen Yang
    testified about Porter’s access to patients’ confidential information due to her
    employment at the University. Dr. Yang worked at the University between 2006
    and 2010 as an assistant professor in the same department as Porter. He also
    11
    Case: 12-20095    Document: 00512456949      Page: 12    Date Filed: 12/02/2013
    No. 12-20095
    treated patients at the Hospital. Dr. Yang explained that he handled patients’
    medical charts during his day-to-day practice. Those charts included what the
    Hospital called “face sheets.” The sheets contained information about patients’
    insurance providers such as Medicare. Dr. Yang stated that he was required to
    report charges that he billed and would attach that billing data to the face sheet.
    He then placed the documents in a basket for processing. Dr. Yang knew Porter
    from their working at the University. Her desk as an administrative assistant
    was down the hall from where he placed documents in the basket. He also knew
    that Porter processed patients’ billing information because he had witnessed her
    speaking with a billing company.
    A legal privacy officer who worked for the University testified regarding
    Porter’s employment records.      The officer reviewed documents in Porter’s
    employment file, which revealed one of Porter’s responsibilities was to maintain
    all medical billing and routine office duties. Porter had received advanced
    training on patients’ rights regarding the confidentiality of their health care
    information.
    We disagree with Porter that the evidence was insufficient to support a
    finding of guilt. Porter initially suspected Clifford Ubani and Princewill Njoku
    of fraudulent activity. She still agreed to work for them and admitted to
    referring patients to Family Healthcare and receiving payments in exchange.
    Porter defended her actions based on her belief that they were legitimate
    referrals, but the jury also heard her testify that she received payments for
    patients’ recertifications despite having provided no additional work in
    exchange. Agent Harshaw testified that the patients on a referral list associated
    with Porter were Medicare beneficiaries. According to his testimony, more than
    12
    Case: 12-20095     Document: 00512456949      Page: 13   Date Filed: 12/02/2013
    No. 12-20095
    three-quarters of those beneficiaries were also patients at the Memorial
    Hermann Hospital. This circumstantial evidence, along with the testimony that
    she had direct access to patients’ Medicare information and advanced training
    in confidentiality regulations, was sufficient to prove that Porter knew of the
    unlawful objective of recruiting Medicare beneficiaries and willfully joined the
    agreement with the intent to further that objective.
    3. Counts 20 and 21 (False Statements for Use in Determining Rights)
    It is unlawful to “knowingly and willfully make[] . . . any false statement
    or representation of a material fact for use in determining rights to [any benefit
    or payment under a Federal health care program].” 42 U.S.C. § 1320a-7b(a)(2).
    The jury charge instructed that a false statement is material if it has a natural
    tendency to influence or is capable of influencing the recipient.
    The indictment alleged that Ellis described non-existent symptoms and
    services that were not performed for two patients. On appeal, Ellis concedes the
    evidence showed her nursing notes contained false statements. She argues that
    they were not material because they could not be used to determine either
    patient’s right to home health care. Ellis relies on a claims analyst’s testimony
    that an RN completes the OASIS questionnaire, and the RN and physician
    approve the resulting plans of care. Further, Medicare would not authorize
    payment if these forms merely were signed by an LVN such as Ellis.
    Ellis also acknowledges the testimony that an LVN was legally required
    to keep nursing notes that documented patient care. We conclude these notes
    were material in support of her conviction. The claims analyst explained at trial
    that Medicare required the preservation of nursing notes in the event of an
    audit. Ellis herself testified that Family Healthcare encountered two audits
    13
    Case: 12-20095      Document: 00512456949     Page: 14   Date Filed: 12/02/2013
    No. 12-20095
    while she worked with the company. In addition, Agent Harshaw testified that
    an RN partly relies on an LVN’s nursing notes when completing the
    recertification OASIS. The claims analyst testified that an RN partly would rely
    on nursing notes to determine future treatment.
    Regarding the two patients listed in the indictment for Counts 20 and 21,
    Ellis allegedly provided services for them as their LVN. Both patients were
    recertified for a second period of home health care. An RN was associated with
    each recertification.    Family Healthcare billed Medicare for both patients.
    Under either circumstance, Ellis’s false statements on her nursing notes were
    material and capable of influence for purposes of determining rights to payment
    by Medicare. The evidence was sufficient to sustain Ellis’s conviction.
    B. Multiplicity
    Njoku argues her two conspiracy convictions in Counts 1 and 2 are
    multiplicitous.   Before trial, Njoku failed to object to her indictment as
    multiplicitous. See FED. R. CRIM. P. 12(b)(3). Such a claim cannot now be raised
    on appeal. United States v. Dixon, 
    273 F.3d 636
    , 642 (5th Cir. 2001). Thus, the
    convictions on each count stand.
    A challenge to sentences as being the result of multiplicitous indictments
    can be considered even if only presented on appeal. 
    Id. Because Njoku
    failed to
    object in the district court, we review only for plain error. United States v. Ogba,
    
    526 F.3d 214
    , 232 (5th Cir. 2008). This requires a showing of “(1) error, (2) that
    is plain, and (3) that affects substantial rights.” 
    Id. at 236.
    If shown, we have
    discretion to correct the error if it “seriously affects the fairness, integrity, or
    public reputation of judicial proceedings.” 
    Id. at 236-37.

    No. 12-20095
    We interpret Njoku’s argument to rest on the claim that although she was
    charged with violating two different statutes, one of the violations could be the
    lesser included offense of the other. In this circumstance, we consider whether
    “each offense requires proof of an element that the other does not . . . .” United
    States v. Woerner, 
    709 F.3d 527
    , 539 (5th Cir. 2013) (citing Blockburger v. United
    States, 
    284 U.S. 299
    , 303-05 (1932).
    Njoku relies on a decision in which we reviewed whether there was
    multiplicity in charges for the substantive crimes of health care fraud under 18
    U.S.C. § 1347 and illegal remunerations under 42 U.S.C. § 1320a-7b(b). 
    Ogba, 526 F.3d at 233-34
    . The court initially distinguished the crimes:
    [T]he statutes each require proof of an additional fact that the other
    does not. Illegal remuneration does not require fraud or falsity; a
    defendant could be honest about accepting illegal remunerations.
    Health care fraud, on the other hand, requires fraud or falsity but
    does not require payment in return for a referral.
    
    Id. at 234.
    The court then stated that if a defendant’s “healthcare fraud
    conviction were based entirely on proof of his receipt of kickbacks, which he did
    dishonestly, then a conviction for illegal remuneration is a lesser included
    offense of healthcare fraud . . . .” 
    Id. The Ogba
    jury charge included various
    theories of health care fraud, and the indictment alleged alternative methods by
    which the scheme was committed. 
    Id. at 235.
    One of those means included
    paying or receiving remunerations in exchange for referrals, i.e., kickbacks. 
    Id. The court
    explained the jury could have based its finding of guilt on health care
    fraud solely on the theory of illegal remunerations. 
    Id. at 236.
    Accordingly, the
    court concluded that the sentence violated the Double Jeopardy Clause. 
    Id. 15 Case:
    12-20095    Document: 00512456949       Page: 16   Date Filed: 12/02/2013
    No. 12-20095
    The present case is distinguishable. The two convictions involve two
    conspiracies, one under 18 U.S.C. § 1349 and the other under 18 U.S.C. § 371.
    One statute requires that the government prove an additional fact that the other
    does not. Section 1349 requires proof of a conspiracy to commit an offense of
    fraud and that such fraud is the object of the conspiracy. Section 371 prohibits
    two or more persons from conspiring to commit any offense against the United
    States. Further, Section 371 requires proof of an overt act, which Section 1349
    does not. 
    Grant, 683 F.3d at 643
    ; 
    Mauskar, 557 F.3d at 229
    .
    As the court did in Ogba, we also examine the jury charge. To find Njoku
    guilty of the conspiracy to commit health care fraud in Count 1, the jury was
    required to find the following beyond a reasonable doubt:
    First: That two or more persons made an agreement to commit the
    crime of health care fraud as charged in the Indictment;
    Second: That the defendant knew the unlawful purpose of the
    agreement; and
    Third: That the defendant joined in the agreement willfully, that is,
    with the intent to further the unlawful purpose.
    The indictment described the unlawful purpose in Count 1 as including the
    receipt of kickbacks in addition to the submission of fraudulent claims to
    Medicare. The charge of conspiracy to receive or pay health care kickbacks in
    Count 2 required the jury to find that the defendant “knew the unlawful purpose
    of the agreement and joined in it willfully, that is, with the intent to further the
    unlawful purpose.” The indictment described the unlawful purpose in Count 2
    as receiving or paying kickbacks “in exchange for providing Medicare beneficiary
    16
    Case: 12-20095     Document: 00512456949      Page: 17   Date Filed: 12/02/2013
    No. 12-20095
    information that was used to submit claims to Medicare.” Unlike in Count 1, the
    submitted claims did not need to be fraudulent.
    In order for the jury to find Njoku guilty of the charge in Count 2, it had
    to find “[t]hat one of the conspirators during the existence of the conspiracy
    knowingly committed at least one of the overt acts described in the
    Indictment . . . .” The indictment listed specific acts: (a) the payment of a
    referral check from Clifford Ubani to Ellis, (b) the payment of a referral check
    from Princewill Njoku to Sammie Wilson, and (c) the payment of a referral check
    from Clifford Ubani to another recruiter. In contrast, the conspiracy for Count
    1 listed acts that the conspirators intended, but there was no requirement that
    those acts have actually occurred.
    Njoku has not shown plain error as to her multiplicity claim.
    C. Double Jeopardy
    1. Count 1
    Ellis contends that her conspiracy conviction under Count 1 violates the
    Double Jeopardy Clause of the Fifth Amendment because she was acquitted of
    conspiracy in a previous prosecution. In October 2009, Ellis was indicted on one
    count of conspiracy to commit health care fraud in violation of 18 U.S.C. § 1349.
    The indictment identified Ellis as an LVN who worked for Family Healthcare
    and recruited Medicare beneficiaries for the purpose of filing claims with
    Medicare for durable medical equipment (“DME”) that was medically
    unnecessary or not provided. The indictment further alleged that Ellis received
    kickbacks for the referrals. After a trial by jury, Ellis was found not guilty.
    17
    Case: 12-20095     Document: 00512456949     Page: 18   Date Filed: 12/02/2013
    No. 12-20095
    In October 2010, Ellis was charged in the present case with conspiracy
    under the same statute. The indictment here alleged that Ellis worked for
    Family Healthcare as an LVN who provided nursing services to patients and
    referred Medicare beneficiaries, in exchange for kickbacks, for the purpose of
    filing fraudulent claims with Medicare for skilled nursing services that were
    medically unnecessary or not provided. This time she was found guilty.
    We review the double jeopardy claim de novo. United States v. El-Mezain,
    
    664 F.3d 467
    , 546 (5th Cir. 2011). The Fifth Amendment “protects against a
    second prosecution for the same offense after acquittal.” United States v. Levy,
    
    803 F.2d 1390
    , 1393 (5th Cir. 1986) (quoting North Carolina v. Pearce, 
    395 U.S. 711
    , 717 (1969)). The issue for us “is whether there was one agreement and one
    conspiracy or more than one agreement and more than one conspiracy.” El-
    
    Mezain, 664 F.3d at 546
    .
    First, Ellis must establish “a prima facie nonfrivolous double jeopardy
    claim.” United States v. Rabhan, 
    628 F.3d 200
    , 204 (5th Cir. 2010). Ellis has
    done so by the introduction of her indictment in the DME case along with
    additional material in the record. 
    Id. A nonfrivolous
    claim creates for the
    Government the burden to prove “by a preponderance of the evidence that the
    defendant has been charged in separate conspiracies.” 
    Id. We are
    guided by five factors, none of which is determinative:
    1) time; 2) persons acting as co-conspirators; 3) the statutory
    offenses charged in the indictments; 4) the overt acts charged by the
    government or any other description of the offense charged that
    indicates the nature and scope of the activity that the government
    sought to punish in each case; and 5) places where the events
    alleged as part of the conspiracy took place.
    18
    Case: 12-20095     Document: 00512456949      Page: 19    Date Filed: 12/02/2013

    El-
    Mezain, 664 F.3d at 546
    . Our review will explain why there were two
    agreements and two conspiracies.
    a. Time
    An overlapping time period supports a finding that there was only one
    conspiracy, particularly if that period is lengthy. 
    Rabhan, 628 F.3d at 205
    .
    Here, the skilled nursing conspiracy allegedly began in April 2006 and lasted
    through August 2009. The DME conspiracy allegedly began in August 2007 and
    ended at some point between June and October 2009. This overlap is sufficient
    under Rabhan and supports that only one conspiracy existed. 
    Id. b. Co-conspirators
          “An overlap in personnel participating in the conspiracy, particularly in
    key personnel, indicates a single conspiracy.” 
    Id. When those
    key figures “serve
    different functions for purposes of the conspiracies, it is less likely that there is
    a single agreement.” 
    El-Mezain, 664 F.3d at 547
    .
    Ellis alleges an overlap in two key personnel: Clifford Ubani and
    Princewill Njoku. Ellis argues these men were the owners of Family Healthcare
    and orchestrated both the DME and skilled nursing schemes.
    The DME indictment identified both men as owners and operators of
    Family Healthcare, and the indictment further revealed that Princewill Njoku
    was an RN. They allegedly maintained a valid Medicare provider number to
    submit claims for the cost of DME, controlled the day-to-day operations, paid
    kickbacks to recruiters, obtained prescriptions, submitted claims, and caused the
    transfer of fraudulent proceeds.
    The skilled nursing indictment identified both men as owners and
    operators of Family Healthcare.        It detailed that Clifford Ubani was the
    19
    Case: 12-20095     Document: 00512456949     Page: 20   Date Filed: 12/02/2013
    No. 12-20095
    company’s chief financial officer, and Princewill Njoku was an RN who
    purportedly provided home health care services to referred beneficiaries.
    Clifford Ubani’s role was paying kickbacks for referrals and submitting
    fraudulent claims.    Princewill Njoku’s role was more involved, including
    falsifying patient files to make it appear beneficiaries received skilled nursing
    care services that were not provided, approving plans of care that were not
    medically necessary, and providing recertifications despite knowing the services
    were not necessary.
    Clifford Ubani testified at the DME trial that his main concentration was
    on DME and he had little involvement in the skilled nursing scheme. He had
    attempted to start a DME business before he got involved with Family
    Healthcare. Clifford Ubani explained that, as the chief financial officer, he
    signed checks when they were given to him. There was evidence suggesting that
    Princewill Njoku, the RN, took the leading role in the skilled nursing scheme.
    The bifurcation of responsibilities is also revealed by Princewill Njoku
    becoming the owner of Family Healthcare in December 2008. Clifford Ubani
    began a new company named Family DME, Incorporated, which used a different
    Medicare provider number. Clifford Ubani testified that these events signified
    an end to the joint venture. “I was on my own. He was on his own, too. The old
    [company] was abandoned.” Evidence also showed that the companies’ records
    were separate and that each used separate bank accounts.
    Somewhat offsetting those facts, there was testimony showing the money
    in the accounts occasionally was commingled.          Both men shared some
    responsibilities. The absence of complete consistency in the separation, though,
    does not effectively rejoin the two schemes.      Further, Clifford Ubani and
    20
    Case: 12-20095      Document: 00512456949        Page: 21     Date Filed: 12/02/2013
    No. 12-20095
    Princewill Njoku had different roles in each scheme. Adelma Sevilla testified
    that both men interviewed her for employment, but she viewed Clifford Ubani
    as a financial advisor and Princewill Njoku as the director of nursing. That the
    two men served different functions in each scheme supports the finding that two
    conspiracies existed. 
    El-Mezain, 664 F.3d at 547
    .
    Ellis insists there was an overlap in six less-central conspirators, namely
    four recruiters (including herself) and two physicians. Testimony showed that
    the four recruiters referred beneficiaries for both DME and home health care.
    The two physicians certified prescriptions for both DME and home health care.4
    It is relevant, though, that other co-conspirators, such as Caroline Njoku and
    Ezinne Ubani, actively participated in the skilled nursing scheme but had no
    apparent role in the DME scheme. The DME case involved fewer participants
    and a more limited plan that included recruiting Medicare beneficiaries,
    providing equipment, and submitting claims. The skilled nursing case engaged
    Princewill Njoku in a different function as an RN and required the additional
    work of medically trained nurses, including Caroline Njoku and Ezinne Ubani,
    providing various degrees of services and representations.                     Although
    some characters were interwoven into both schemes, such overlap in this context
    does not convincingly support a contrary finding that a single conspiracy existed.
    See 
    id. c. Statutory
    Offenses
    Ellis was charged in both prosecutions with conspiracy under 18 U.S.C.
    § 1349 to commit health care fraud through a violation of 18 U.S.C. § 1347.

    Clifford Ubani testified in the DME trial that 70 to 80 percent of prescriptions for
    DME were signed by another physician, Dr. Hutchens.
    21

    No. 12-20095
    Thus, there were not additional offenses charged in the skilled nursing
    prosecution, which undermines the argument that two conspiracies existed. See
    
    Rabhan, 628 F.3d at 207
    ; 
    Levy, 803 F.2d at 1395
    .
    d. Nature and Scope of the Activity
    There is some overlap in the description of the offenses charged in each
    indictment. Both indictments alleged that claims were submitted to Medicare
    for either equipment or services that were unnecessary or not provided to
    patients. The patients were recruited through referral sources, and these
    sources received remunerations in exchange for supplying the beneficiaries.
    We are convinced, though, that the Government sought to punish different
    activities in the skilled nursing case and in the DME case. The skilled nursing
    indictment alleged additional manners and means through which the conspiracy
    was accomplished. For example, as an LVN, Ellis allegedly falsified patient files
    to make it appear Medicare beneficiaries qualified for services; Princewill Njoku
    and Ezinne Ubani, who were RNs, allegedly falsified OASIS questionnaires to
    ensure the beneficiaries qualified; the indictment also alleged they approved
    recertifications and plans of care that were not medically necessary.
    There was evidence in both trials of similar activities, including evidence
    of Ellis’s knowledge that the paid referrals were illegal, her employment history,
    and kickback checks. Evidence also shows that some patients may have been
    recruited for and received both DME and home health care services. The
    possible overlap, though, involves only a portion of the activity involved in both
    the DME and the skilled nursing cases.
    We must “review the entire record and take a commonsense approach in
    determining the substance of each alleged conspiracy.” 
    Levy, 803 F.2d at 1395
    .
    22
    Case: 12-20095        Document: 00512456949         Page: 23     Date Filed: 12/02/2013
    No. 12-20095
    The DME indictment focused on Ellis’s activity as a recruiter. The kickback
    checks she received for the DME beneficiary referrals made up the central
    evidence presented against her at trial; these checks were not admitted into
    evidence in the skilled nursing trial. The skilled nursing trial involved evidence
    regarding Ellis’s false nursing notes for home health care services, which were
    not part of the DME trial.5 Cf. 
    id. False medical
    certifications were inescapably
    part of the conjunctively listed purposes in the skilled nursing indictment. For
    the jury to find Ellis guilty of the charge in Count 1, it was required to find that
    Ellis knew of this unlawful purpose and joined this agreement with the intent
    to further that purpose. We find this activity was of a different nature and scope
    than the referrals. Accordingly, this factor weighs in favor of finding two
    conspiracies existed.
    e. Places
    The Government conceded in its response in opposition to Ellis’s motion
    to dismiss the indictment that the location of the acts weigh in favor of finding
    a single conspiracy. Additionally, the evidence shows that the two schemes were
    conducted out of a single office in Houston and later separated by only three
    5
    Clifford Ubani testified at the DME trial that there were prescription forms with
    check boxes that Family Healthcare’s employees generated for physicians to sign. Ana
    Quinteros testified at the DME trial that recruiters would also measure patients to determine
    the appropriate size of the equipment. Her testimony revealed, though, that the forms were
    pre-written only for the doctors that Family Healthcare paid for their signatures. The forms
    did not require the signature of a medically licensed nurse. Ellis testified that she had never
    filled out such a form. In contrast, the nursing notes involved in the skilled nursing case
    required documentation of patient conditions observed and treated by a medically licensed
    nurse, whose representations were subsequently used to determine a patient’s need for
    additional episodes of care and preserved in addition the physician’s prescription for home
    health care.
    23

    office suites. This factor weighs in favor of finding one conspiracy existed.
    
    Rabhan, 628 F.3d at 208
    .
    In conclusion, the time, statutory offenses, and places involved suggest
    that there was one agreement. Nevertheless, we hold that two agreements and
    two conspiracies existed because of the separate functions that central co-
    conspirators provided in each scheme and the distinctive activity that the
    Government sought to punish in each case. See 
    El-Mezain, 664 F.3d at 551
    . We
    reject Ellis’s argument that the Double Jeopardy Clause was violated.
    2. Counts 2-5
    Ellis next argues that when she was acquitted of conspiracy in the DME
    trial, the jury necessarily determined that she did not know her paid referrals
    were illegal. The Government in the current prosecution had to prove she acted
    willfully (as well as knowingly) to convict her on Counts 2 through 5. Count 2
    charged Ellis with conspiracy under 18 U.S.C. § 371 for willfully receiving
    remuneration in exchange for referring beneficiaries, in violation of 42 U.S.C.
    § 1320a-7b(b)(1). Counts 3 through 5 charged Ellis with willfully receiving those
    remunerations in violation of Section 1320a-7b(b)(1). The jury instructions
    defined the word “willfully” to mean “with the intent to do something the law
    forbids; that is with the bad purpose to disobey or disregard the law.” Thus,
    Ellis argues that if the jury in the DME trial necessarily determined that she did
    not intend to do an act the law forbids, the Fifth Amendment prohibits the
    Government from prosecuting on Counts 2 through 5 in the present case. We
    review Ellis’s argument de novo. 
    El-Mezain, 664 F.3d at 551
    .
    In a criminal case, the Double Jeopardy Clause will “bar a subsequent
    prosecution if one of the facts necessarily determined in the former trial is an
    24
    Case: 12-20095    Document: 00512456949      Page: 25    Date Filed: 12/02/2013

    essential element of the subsequent prosecution.” United States v. Sarabia, 
    661 F.3d 225
    , 229 (5th Cir. 2011). Ellis has the burden to demonstrate that whether
    she knew her conduct was unlawful was a fact that the jury necessarily had to
    decide in finding her not guilty. See 
    id. at 229-30.
    We review the record of the
    prior trial to determine “whether a rational jury could have grounded its verdict
    upon an issue other than that which the defendant seeks to foreclose from
    consideration.” 
    Id. at 230.
          The indictment in the DME case charged Ellis with conspiracy to commit
    health care fraud under 18 U.S.C. § 1349. The jury was instructed that in order
    to find Ellis guilty, there must have been: (1) an agreement to commit health
    care fraud; (2) Ellis knew of the unlawful purpose of that agreement; (3) joined
    in it willfully; (4) with the intent to further that purpose. The indictment
    explained that the purpose of the conspiracy was the unlawful enrichment of the
    participants by submitting and concealing false claims to Medicare, receiving the
    proceeds, and diverting them for personal use. The jury instructions further
    defined “willfully” to mean “with the specific intent to do something the law
    forbids; that is to say, with bad purpose either to disobey or disregard the law.”
    We accept for the sake of argument that the evidence in the DME case
    conclusively established an agreement existed. We focus on Ellis’s contention
    that the jury necessarily determined she did not know her conduct was unlawful.
    At the DME trial, the Government presented evidence that Ellis cashed
    checks from Family Healthcare which referenced durable medical equipment,
    specifically arthritis kits. An FBI agent testified that Ellis admitted she knew
    her paid referrals were unlawful. In her own defense, Ellis testified that Clifford
    Ubani and Princewill Njoku described these payments as bonuses and part of an
    25
    Case: 12-20095     Document: 00512456949      Page: 26   Date Filed: 12/02/2013
    No. 12-20095
    incentive program.    She stated that Clifford Ubani called a meeting and
    informed the employees that the company would begin offering arthritis kits to
    patients. Ellis further testified that she did not know that Family Healthcare
    was engaged in illegal conduct with regard to the arthritis kits and never filled
    out a prescription form for DME. Clifford Ubani testified that Ellis was a bona
    fide employee who was paid a salary for her skilled nursing services. He also
    said that he never discussed with Ellis that it was illegal for her to be paid in
    exchange for making referrals, and he did not explain to her how Family
    Healthcare generated income. At closing arguments, Ellis’s counsel pointed out
    to the jury that the evidence revealed no document that contained Ellis’s
    handwriting or signature. The jury found Ellis not guilty.
    According to the record, there were two forms of intent that had to be
    proven in the DME trial: (1) intent to do something the law forbids and (2) intent
    to further the unlawful purpose of the conspiracy, which included the submission
    and concealment of false claims to Medicare. Jurors could have believed the
    testimony showing she did not know her paid referrals were illegal. The jury
    could have also found she knew her paid referrals were unlawful but believed
    she did not know about the fraudulent claims submitted for DME or that she did
    not intend to further the unlawful purpose as charged in the indictment.
    Because our inquiry is to determine what the jury “must have decided,” Ellis has
    failed to show she was twice put in jeopardy because of this subsequent
    prosecution. 
    Id. at 232.
    D. Former Testimony
    Ellis argues the district court erred in excluding portions of Clifford
    Ubani’s former testimony. Although Clifford Ubani testified in the DME trial,
    26
    Case: 12-20095    Document: 00512456949       Page: 27   Date Filed: 12/02/2013
    No. 12-20095
    in the present case the court sustained his invocation of the right against self-
    incrimination. On the seventh day of trial, the district court asked for a definite
    list of which parts of the DME transcript Ellis sought to admit. Ellis provided
    line numbers from the transcript that totaled 22 pages of testimony. After
    hearing the parties arguments and reviewing the excerpts, the district court
    ruled against the admission of the evidence because it did not meet an exception
    to the rule against the admission of hearsay. FED. R. EVID. 802. Alternatively,
    the court determined that the probative value of the testimony was weak and
    that the dangers of confusing the issues and wasting time substantially
    outweighed that probative value. FED. R. EVID. 403.
    We review the district court’s decision to exclude the evidence for an abuse
    of discretion. See United States v. Saldana, 
    427 F.3d 298
    , 306 (5th Cir. 2005).
    We do not decide whether the former testimony was admissible under the rules
    of hearsay because Ellis fails to show that the district court abused its discretion
    in alternatively excluding the evidence on relevancy grounds. See 
    id. at 307.
          The first selected portions of Clifford Ubani’s testimony revealed general
    information about Family Healthcare and his position there. Next, Clifford
    Ubani explained that Ellis was employed as a skilled nurse and that at the time
    Ellis was hired, on July 7, 2006, Family Healthcare was not yet engaged in
    distributing DME. Clifford Ubani said that on the date Ellis was hired, he did
    not explain to her how the company generated income, did not believe the
    company’s actions were illegal, and did not have a conversation with Ellis about
    the legality of Family Healthcare’s operations. He testified that the company
    used two different checking accounts to split the money involved in skilled
    nursing and DME. After counsel inquired about a check written to Ellis for
    27
    Case: 12-20095    Document: 00512456949       Page: 28    Date Filed: 12/02/2013
    No. 12-20095
    “marketing material,” Clifford Ubani revealed that money was occasionally
    commingled between the accounts. He stated that the marketing efforts were
    legal. When counsel asked whether Ellis ever agreed with him to do something
    illegal, Clifford Ubani said “No.” Finally, he testified that Ellis was paid bonuses
    before the company opened the DME company.
    On appeal, Ellis alleges the central issue in her trial was whether she
    willfully agreed to a scheme to defraud Medicare.            In her argument for
    admissibility under the residual hearsay exception, Federal Rule of Evidence
    807, Ellis contends the probative value of Clifford Ubani’s statement that he
    never agreed with Ellis to do something unlawful was high. Ellis’s extensive
    experience in nursing and the FBI agent’s testimony supported a finding that
    she knew her paid referrals were unlawful. Ellis’s testimony, on the other hand,
    denied any knowledge. Thus, supportive testimony from Clifford Ubani would
    have had some probative value, particularly for the time period after Ellis began
    working for Family Healthcare in 2006 and before DME sales began in 2007.
    But this is only part of the relevance inquiry.
    Ellis contends that there was nothing misleading about Clifford Ubani’s
    testimony that he had not discussed unlawful activity with Ellis. In the first
    part of the selected testimony, counsel asked Clifford Ubani whether he had a
    conversation with Ellis on July 7, 2006 about engaging in illegal activity. He
    said, “No.” What is missing from Ellis’s selected portion of the evidence is
    Clifford Ubani’s testimony that he did not usually hire nurses by himself and
    that he knew Ellis had been hired because Princewill Njoku told him about it.
    Counsel repeatedly focused on the specific date Ellis was hired in eliciting
    Clifford Ubani’s response, despite the other evidence, which Ellis did not
    28
    Case: 12-20095    Document: 00512456949      Page: 29   Date Filed: 12/02/2013
    No. 12-20095
    ultimately select for admission, showing Clifford Ubani may not have personally
    hired Ellis.
    The second reference in Clifford Ubani’s testimony to the absence of an
    unlawful agreement appears later in the transcript. Clifford Ubani’s testimony
    had shown that Ellis was hired at Family Healthcare in 2006. Counsel then
    turned the questioning to the time period in 2007 when the company began
    distributing DME. Counsel asked whether the same account used to pay
    employees in 2006 was used to pay through 2008. Clifford Ubani explained that
    two separate checking accounts existed, one for skilled nursing and one for DME.
    He later clarified that, if necessary, the money would be commingled.
    Immediately after discussing the subject of a check for “marketing material,”
    counsel said, “So, when, in your mind, was there an agreement made with Mary
    Ellis? Did y’all discuss, saying ‘We’re going to do something illegal. This is
    wrong, but we’re going to do it anyway?’ Did she ever agree with you to do
    something illegal?” Clifford Ubani responded, “No.”
    The potentially confusing aspect of this excerpt is the ambiguity as to what
    activity the statement refers. Thus, the elicited affirmance that Clifford Ubani
    did not “ever” have an agreement with Ellis may be taken out of context if the
    testimony discussed referrals for DME, which were outside the scope of the
    present indictment.
    Accordingly, the district court’s concern was reasonable that the admission
    of this selected testimony would require additional evidence and risk having the
    jury decide an essential element on an impermissible basis. There was in fact
    some parts of the prior testimony that were misleading or confusing. We will not
    disturb the district court’s discretionary ruling.

    E. The Right to Present a Complete Defense
    Ellis argues that the district court’s exclusion of Clifford Ubani’s former
    testimony violated her constitutional right to present a complete defense. This
    court reviews Sixth Amendment claims de novo, and evidentiary rulings for
    abuse of discretion. United States v. Templeton, 
    624 F.3d 215
    , 223 (5th Cir.
    2010).
    The Sixth Amendment right to present a complete defense may be violated
    by “evidence rules that infringe upon a weighty interest of the accused and are
    arbitrary or disproportionate to the purposes they are designed to serve.”
    Holmes v. South Carolina, 
    547 U.S. 319
    , 324 (2006) (quotation marks omitted).
    Even so, “well-established rules of evidence permit trial judges to exclude
    evidence if its probative value is outweighed by certain other factors such as
    unfair prejudice, confusion of the issues, or potential to mislead the jury.” 
    Id. at 326.
    Because one of the reasons the district court excluded the former testimony
    was that its probative value was substantially outweighed by the potential to
    mislead, we reject the contention that any constitutional rights were violated.
    See United States v. Eff, 
    524 F.3d 712
    , 720 (5th Cir. 2008).
    F. Sentencing
    1. Mary Ellis
    Ellis contends the district court erred in calculating her offense level at
    sentencing. In considering her argument, “we review the district court’s factual
    findings for clear error and its interpretation of the Guidelines de novo.”
    
    Mauskar, 557 F.3d at 232
    .
    At sentencing, the district court applied an enhancement under U.S.S.G.
    § 2B1.1(b)(1)(H) (2011) based on an attributable loss of more than $400,000.
    30
    Case: 12-20095    Document: 00512456949      Page: 31    Date Filed: 12/02/2013
    No. 12-20095
    Ellis objected. She argues on appeal that the evidence did not support a finding
    that she subjectively intended to cause such a loss and that the loss was not
    based on her conduct.
    Commentary to Section 2B1.1 states that the “loss is the greater of actual
    loss or intended loss.” § 2B1.1 cmt. n.3(A). Given the arguments at sentencing
    and the court’s stated determinations, we examine the “actual loss,” which is
    “the reasonably foreseeable pecuniary harm that resulted from the offense.”
    U.S.S.G. § 2B1.1 cmt. n.3(A)(i). Actual loss requires a causal connection in fact,
    that is, a finding that Ellis truly caused the loss. See United States v. Olis, 
    429 F.3d 540
    , 545-46 (5th Cir. 2005).       The district court “need only make a
    reasonable estimate of the loss.” § 2B1.1 cmt. n.3(C). The court “is entitled to
    find by a preponderance of the evidence all the facts relevant to the
    determination of a Guideline sentencing range.” 
    Mauskar, 557 F.3d at 234
    .
    The district court estimated that the loss attributable to Ellis was
    $401,000. At sentencing, the Government initially contended the loss was
    $1,025,899.87 and presented an exhibit which listed beneficiaries for whom Ellis
    had prepared at least one nursing note and the amount billed to Medicare for
    each patient. Ellis objected, arguing that she did not know at least 12 of the
    patients on the exhibit. She also contended the total was $131,000 based on the
    patients she admitted to referring, which would have resulted in a reduced
    enhancement. See § 2B1.1(b)(1). The court was persuaded that the Government
    could prove at least $400,000 in loss because the evidence showed that Ellis
    provided skilled nursing services in addition to the referrals of patients who did
    not need those services and were recruited instead of referred by physicians.
    Additionally, the Government directed the court to Trial Exhibit 47, which was
    31
    Case: 12-20095     Document: 00512456949       Page: 32    Date Filed: 12/02/2013
    No. 12-20095
    a summary exhibit of Ellis’s patients and their respective recertifications,
    Medicare claim amounts, and certifying physicians. The total of these claims
    was $760,551.66. Agent Harshaw testified that a person under his direction
    created Trial Exhibit 47 based on claims data, referrals sheets located on the
    computer, and the filed face sheets. Agent Harshaw also stated that he created
    a related exhibit which was admitted and revealed the same amount based on
    the claims data he personally reviewed during his investigation.
    Ellis presented exhibits to show contradictions in the initial summary
    exhibit the Government presented. She also presented a list of 26 patients who
    Adelma Sevilla believed were not homebound. Finally, Ellis narrowed the
    Government’s list of patients and claims down to those associated with Dr.
    Echols, who arguably was more clearly involved in the fraud. The district court
    considered the evidence and ultimately assessed the loss at $401,000. The court
    found the Government’s records more reliable than Ellis’s recollection and based
    its decision on the presented exhibits, including Ellis’s referral list, patient list,
    and logs of patient care admitted at trial.
    On appeal, Ellis argues the district court did not consider evidence that
    contradicted the Government’s evidence that Ellis was a referral source for all
    of the patients in the first sentencing exhibit. At trial, though, Agent Harshaw
    testified that there could be more than one referral source based on his review
    of the evidence. Ellis next argues that she did not recall at least twelve of the
    patients on the Government’s exhibit, but she has not shown clear error in the
    district court’s explicit credibility finding. Third, Ellis contends that some
    patients had prescriptions for home health care, but Agent Harshaw testified
    that out of the hundreds of patient files he reviewed, only three or four had
    32
    Case: 12-20095     Document: 00512456949      Page: 33   Date Filed: 12/02/2013
    No. 12-20095
    prescriptions.    Thus, this contention does not sufficiently alter the loss
    calculation for us to determine there was clear error in the factual findings.
    Further, Ellis contends that some patients were not homebound and that
    the court did not distinguish between legitimate nursing visits and illegitimate
    ones.    She also argues her skilled nursing services were provided after
    beneficiaries had received plans of care, which means Medicare would have
    already paid a percentage of the claims under the bifurcated payment system.
    As the district court reasoned, though, a central idea of this scheme was to
    generate sources of income: Medicare beneficiaries. The claims analyst, who
    had also worked as a nurse, testified at trial that a physician’s prescription was
    required before home health care could be initiated. Although evaluations could
    be conducted before that prescription was written, that was not the general
    practice according to her experience. In fact, almost all referrals came from
    treating physicians. Here, Agent Harshaw’s testimony provided evidence that
    only three or four patients had prescriptions.
    Ellis’s skilled nursing services were also important to the scheme.
    Evidence shows that Ubani was the RN for many patients for whom Ellis was
    listed as the LVN. Ana Quinteros testified at trial that Ellis did not provide all
    of the skilled nursing services she reported and that OASIS questionnaires were
    signed by Ubani without her having seen the patients. In fact, the OASIS
    questionnaire would be blank, signed by the patient, and subsequently
    completed to obtain a physician’s signature and permit the Medicare claim.
    Thus, the inquiry does not turn on whether each patient ultimately was
    not homebound or in need of skilled nursing services because evidence proved
    that Ellis engaged in conspiracies to commit health care fraud and receive
    33
    Case: 12-20095    Document: 00512456949      Page: 34    Date Filed: 12/02/2013
    No. 12-20095
    kickbacks in exchange for referrals, which ultimately resulted in payments by
    Medicare. This conduct is prohibited. Her recruitment and nursing activities
    provided direct causal links to the claims and pecuniary harm as she referred
    patients who did not have prescriptions and falsified her nursing notes, which
    were used in the process of generating plans of care and subsequent
    recertifications. Ellis’s position at Family Healthcare and relationships with co-
    workers and patients ensure that the losses she caused were reasonably
    foreseeable. The Government presented reliable evidence to prove it was more
    likely than not that Ellis was accountable for over $700,000 in Medicare claims
    related to the conspiracies. The district court took into consideration her
    contrary evidence but remained unpersuaded that she was accountable for less
    than $400,000. Ellis has not shown on appeal that the findings were clearly
    erroneous or that the court misapplied the law. Accordingly, her argument that
    her sentence should be vacated is rejected.
    2. Ezinne Ubani
    Ubani argues the district court erroneously calculated her offense level at
    sentencing.   We review the court’s factual findings for clear error and its
    interpretation of the Sentencing Guidelines de novo. United States v. Miller, 
    607 F.3d 144
    , 147 (5th Cir. 2010). Findings are upheld if they are “plausible in light
    of the record as a whole.” 
    Id. at 148.
          Ubani objected to the application of two sentencing enhancements: one
    two-level increase for her role in the offense as a manger or supervisor and
    another two-level increase for an abuse of trust. At sentencing, the district court
    overruled both objections after hearing arguments and reviewing the evidence.
    34
    Case: 12-20095     Document: 00512456949     Page: 35   Date Filed: 12/02/2013
    No. 12-20095
    We first address Section 3B1.1(c), which provides for a two-level increase
    in the offense level if the defendant was a manager or supervisor. The district
    court relied on documentation showing Ubani held herself out as a person who
    coordinated and oversaw patient services and beneficiary assessments. The
    court also relied on evidence that showed Ubani assumed Princewill Njoku’s
    administrative duties in his absence. Finally, the court acknowledged one
    witness’s testimony that she reported to Ubani while working as a recruiter.
    Ubani argues the evidence showed that she was an RN who merely worked
    under the direction of Clifford Ubani and Prinecwill Njoku and evidence of any
    managerial role was insufficient. We disagree. Agent Harshaw testified that
    both the articles of incorporation for Family Healthcare and its Medicare
    provider application listed Ubani as a director/officer of the company. He also
    discovered her resume during the investigation, which stated that her job
    responsibilities at Family Healthcare included coordinating and overseeing all
    patient services provided by agency personnel.       It also revealed that she
    assumed the duties of administrator in Princewill Njoku’s absence. A form
    submitted to the Texas Department of Disability and Aging listed Ubani as
    Family Healthcare’s director of nursing. Ubani suggests in her argument that
    the documentation reflected a period of time outside of the scope of the
    indictment, but Agent Harshaw’s evidence shows otherwise, revealing a form
    dated November 20, 2007, which showed Ubani was still a delegated official to
    act on the company’s behalf.
    Further, the testimony of others who worked with Ubani supported the
    court’s finding that Ubani took on a supervisory role. Even if we did find error,
    it would be harmless because the district court explicitly stated that it would
    35
    Case: 12-20095     Document: 00512456949     Page: 36   Date Filed: 12/02/2013
    No. 12-20095
    give the same sentence even if the enhancement did not apply. United States v.
    Richardson, 
    676 F.3d 491
    , 511-12 (5th Cir. 2012).
    We next discuss Section 3B1.3, which provides for a two-level
    enhancement if Ubani abused a position of trust. This trust “refers to a position
    of public or private trust characterized by professional or managerial discretion
    (i.e., substantial discretionary judgment that is ordinarily given considerable
    deference).” § 3B1.3 cmt. 1. Such individuals generally have less supervision
    than other employees. 
    Id. The person’s
    position “must have contributed in some
    significant way to facilitating the commission or concealment of the offense.” 
    Id. The district
    court determined that Medicare invests an important trust in RNs
    who complete OASIS questionnaires and certify plans of care for the initial
    episodes of care and the recertifications, which the court stated was the center
    of Ubani’s activity.
    Ubani contends that because she did not exercise supervisory discretion
    in her role, her position as a registered nurse is insufficient for the enhancement
    to apply. We have found, though, that the evidence did show Ubani was, in fact,
    acting as a supervisor over other employees.
    In addition, Cynthia Garza-Williams testified that she would take blank
    OASIS forms to patients for their signatures. She explained that she would
    bring the forms back to the office where Ubani would fill in information without
    having seen the patients and then certify the assessments as an RN. Plans of
    care were taken to Dr. Echols, who was paid for his certifications. Garza-
    Williams testified that Dr. Echols would sign whatever was given to him. The
    testimony from the claims analyst and agent Harshaw show that Medicare relied
    on the representations made by physicians and RNs, and under this described
    36
    Case: 12-20095    Document: 00512456949      Page: 37   Date Filed: 12/02/2013
    No. 12-20095
    scheme, Ubani essentially made the determination that specific patients
    qualified for home health care. Accordingly, the enhancement under Section
    3B1.3 was proper. 
    Miller, 607 F.3d at 149
    .
    3. Caroline Njoku
    The district court’s oral pronouncement of Njoku’s sentence on Count 2
    was 60 months’ imprisonment. The written judgment provides for a sentence of
    63 months.    When “there is any variation between the oral and written
    pronouncements of sentence, the oral sentence prevails.” United States v.
    Martinez, 
    250 F.3d 941
    , 942 (5th Cir. 2001). We will remand so that the district
    court may amend its written judgment to conform to its oral sentence.
    We REMAND for the district court to amend Njoku’s written judgment to
    conform to her oral sentence. In all other respects, we AFFIRM the district
    court’s judgment.
