OPINION ∗

______________

∗

This disposition is not an opinion of the full court and pursuant to I.O.P. 5.7 does

not constitute binding precedent.

SHWARTZ, Circuit Judge.

Samirkumar Shah appeals his conviction and sentence for health care fraud.

Because the District Court correctly denied his motions to disqualify the United States

Attorney’s Office (“USAO”), for a continuance, and for a judgment of acquittal, and

because his sentence is procedurally and substantively reasonable, we will affirm.

I

A

Shah practiced cardiology in multiple offices in Pennsylvania. Among other

things, Shah prescribed external counterpulsion (ECP) treatment, which is designed to

increase blood flow to the heart using compression cuffs around the patient’s legs while

they are lying down. Shah purchased ECP beds and billed insurers, including Medicaid

and Medicare plans, for ECP treatment.

Medicaid and Medicare have three limitations for reimbursement of ECP

treatment. First, the programs cover ECP treatment only for patients who suffer from

angina (chest pain). Second, the programs will only reimburse for ECP treatment that

was conducted under a physician’s direct supervision. Third, the programs restrict billing

for reimbursement. Specifically, a system of codes is used to identify the service

rendered, and each coded service is assigned a price. ECP treatment is assigned code

G0166, which is a “bundled code” because it includes companion treatments. 1 App. 197.

As result, physicians who bill code G0166 may not also bill the separate codes for the

1

The companion treatments bundled in G0166 include echocardiograms, Doppler

tests, pulse oximetries, and plethysmographies.

2

companion treatments on the same day “unless they are medically necessary and

delivered in a clinical setting not involving ECP therapy.” S. App. 6. The ECP bed

supplier provided Shah with guidelines informing him of these limitations.

Insurers audited Shah’s billing and told him that he improperly billed ECP

treatments by using both the G0166 code and codes for companion treatments and that

the medical necessity of many of his ECP treatments was unsubstantiated. Although

Shah’s agreements with insurers required that he only seek reimbursement for medically

necessary treatments, and he told one insurer that he instructed his billing department to

remove the incorrect codes, he in fact directed his third-party billing service to continue

billing “[a]ll four codes.” App. 836.

In addition to ignoring insurers’ directives, Shah (1) prescribed ECP for patients,

including an undercover agent, who did not suffer chest pain, telling some patients that

ECP treatment would make them “younger and smarter” and could help with conditions

including high and low blood pressure, obesity, erectile dysfunction, and restless leg

syndrome, App. 385; and (2) was “very often” not present—nor was any doctor—to

supervise patients’ ECP treatments, App. 457-58. Shah (1) told his staff that all patients

had angina; (2) instructed staff to “beef[] up” patient files before insurance reviews, long

after treatment was provided, App. 327; and (3) used pre-printed forms that included

angina diagnoses. Notably, during an interview with the Pennsylvania Attorney

General’s Office, Shah stated that he reported angina diagnoses for patients who did not

have that condition “[f]or reimbursement purposes.” App. 1151.

3

B

A grand jury indicted Shah for two counts of health care fraud in violation of 18

U.S.C. § 1347.

On the first day of jury selection, Shah moved to disqualify the entire USAO and

sought a continuance to conduct additional discovery.

Shah’s disqualification motion arose out of his prior representation by Tina Miller,

who represented Shah until June 2017, and then, ten months later, joined the USAO as a

supervisory Assistant U.S. Attorney (“AUSA”). Shah argued that because Miller became

a supervisor in the office prosecuting him, there was “both a conflict of interest and an

appearance of a loss of impartiality.” D. Ct. ECF No. 145 at 7. The District Court denied

the motion, noting that it did not “see any issue of any facts demonstrating a conflict of

[interest]” and emphasizing the need to avoid delaying the trial. App. 67. 2

Shah also sought a continuance so he could have an expert review 350 patient files

seized from his offices. The Government responded that the records had been available

2

After the Court ruled, it received declarations from Miller and the two AUSAs

handling the trial. Miller stated that she did not discuss employment with the USAO

when she represented Shah and, once she joined the office, she had no discussions about

or involvement in any cases in which she had played a role while in private practice. She

also represented that she divulged no confidential information learned during her

representation of Shah to any USAO employee or investigative agency. The two

AUSAs’ affidavits likewise stated that Miller was not involved in Shah’s prosecution and

did not divulge any client confidences. One AUSA added that her only discussion with

Miller regarding Shah’s prosecution involved her telling Miller that she was unable to

assist on a separate matter because she, unbeknownst to Miller, “would be in . . . the trial

of [Shah].” App. 90.

After trial, the District Court revisited Shah’s disqualification motion, again held

that disqualification of the entire USAO was inappropriate “given the lack of . . . Miller’s

4

to him for years and thus a continuance was inappropriate. The Court denied the request

for a continuance as untimely.

C

The trial commenced, and the Government presented thirty-two witnesses,

including Shah’s patients and employees, the ECP bed supplier, insurers, his third-party

billing service, and law enforcement officers. After the government rested, Shah moved

for judgment of acquittal on Count Two, which the District Court denied. The jury found

Shah guilty on both counts of health care fraud.

D

The District Court held a sentencing hearing to calculate the loss to insurers from

Shah’s conduct. FBI Special Agent Brooklynn Riordan testified that, for each insurer,

she calculated (1) the average amount Shah billed and (2) the average amount the insurer

reimbursed Shah, and identified, by dividing the average amount reimbursed by the

average amount billed, a reimbursement rate. She then multiplied that rate by the total

billing to that insurer, which, across all insurers, yielded a total loss of $5,919,100.00.

The Government recommended reducing the total loss amount by 50%, which had the

effect of treating half of Shah’s billing for ECP treatment and companion codes as

legitimate, even though there was no evidence that he ever legitimately used those codes.

The District Court accepted the loss calculation over Shah’s objection.

involvement in the government’s prosecution of defendant,” and declined to hold an

evidentiary hearing. App. 50.

5

The Court sentenced Shah to concurrent terms of 78 months’ imprisonment and

three years’ supervised release and ordered that he pay $1,234,983.60 in restitution.

Shah appeals.

A

We will address, in turn, Shah’s challenges to the District Court’s orders denying

his motions to disqualify the entire USAO, for a continuance to conduct additional

discovery, and for judgment of acquittal on Count Two.

14

The District Court properly denied Shah’s motion to disqualify the entire USAO.

First, the District Court’s decision was not arbitrary. We have recognized that “[a]s long

as the court makes a ‘reasoned determination on the basis of a fully prepared record,’ its

decision will not be deemed arbitrary.” United States v. Stewart, 185 F.3d 112, 120 (3d

Cir. 1999) (quoting United States v. Voigt, 89 F.3d 1050, 1075 (3d Cir. 1996)). Here, the

District Court complied with its obligations, as it heard oral argument and received

written submissions from both Shah and the Government on this issue and made its

3

The District Court had jurisdiction under 18 U.S.C. § 3231. We have jurisdiction

under 28 U.S.C. § 1291 and 18 U.S.C. § 3742(a).

4

“Our standard of review on an attorney disqualification issue includes both

deferential and de novo elements. To the extent that the district court made factual

findings, our review is for clear error . . . . [W]e exercise plenary review to determine

whether the district court’s disqualification was arbitrary in the sense that the court did

not appropriately balance proper considerations of judicial administration against the

United States’ right to prosecute the matter through counsel of its choice . . . . If the

disqualification was not arbitrary, we use an abuse of discretion standard . . . .” United

States v. Whittaker, 268 F.3d 185, 193-94 (3d Cir. 2001).

6

decision based on a complete record, including declarations from Miller and the two

AUSAs handling Shah’s trial. Thus, we review the Court’s ruling for abuse of discretion.

See Whittaker, 268 F.3d at 194.

Second, the District Court did not abuse its discretion. Attorneys practicing before

the United States District Court for the Western District of Pennsylvania must adhere to

the Pennsylvania Supreme Court’s Rules of Professional Conduct. See W.D. Pa. L. Civ.

R. 83.3(A)(2); Pa. Const. art. V § 10. Under the Pennsylvania rules, a lawyer “currently

serving as a public officer or employee . . . shall not . . . participate in any matter in which

the lawyer participated personally and substantially while in private practice.” 204 Pa.

Code R. 1.11(d). While the lawyer who switches sides “is of course disqualified from

participating in the case[,] . . . individual rather than vicarious disqualification is the

general rule.” Commonwealth v. Miller, 422 A.2d 525, 529 (Pa. Super. Ct. 1980)

(quotation marks and citation omitted); see also 204 Pa. Code R. 1.11(d) cmt. (2)

(“Because of the special problems raised by imputation [of a conflict of interest] within a

government agency, [Rule 1.11(d)] does not impute the conflicts of a [government]

lawyer to other associated government officers or employees, although ordinarily it will

be prudent to screen such lawyers.”). This is so because disqualifying an entire

prosecutor’s office, rather than just the conflicted attorney, would impose substantial

costs on taxpayers because it would trigger the need to appoint special prosecutors each

time a member of the defense bar switches sides. See, e.g., Miller, 422 A.2d at 529;

Commonwealth v. Harris, 460 A.2d 747, 749 (Pa. 1983) (calling such an approach

“simply not viable”). Furthermore, it would not address the true concern: to be sure that

7

“the acts of a public prosecutor have [not] actually tainted the proceedings.” Harris, 460

A.2d at 749. Because actual taint must be shown, the mere “appearance of impropriety”

is insufficient to support disqualification of an entire office. 5 See id.

To avoid taint, USAOs use methods to wall off the attorney from cases in which

he played a role while in practice. Disqualification of an entire USAO is required only

when screening devices, aimed at ensuring side-switching counsel is in no way involved

in the case giving rise to the conflict, were not used or were ineffective. United States v.

Goot, 894 F.2d 231, 234-35 (7th Cir. 1990); see United States v. Caggiano, 660 F.2d 184,

191 (6th Cir. 1981) (holding that because an attorney was separated from all participation

on matters affecting his former client, “disqualification of an entire government

department . . . would not be appropriate”).

Here, the affidavits from Miller and the two AUSAs who tried Shah showed

Miller was properly screened. Miller stated that she had “been recused and walled off

from any involvement or oversight” in cases where she represented a defendant,

including Shah’s matter. App. 84. To implement the ethical screen, Miller told attorneys

and supervisors assigned to cases from which she was recused that she could have no

involvement in those cases. As to Shah specifically, Miller stated that she neither

“participated . . . in the prosecution or supervision of this case” nor “divulged any

5

Shah’s reliance on People v. Shinkle, 415 N.E.2d 909 (N.Y. Ct. App. 1980), is

misplaced. Shinkle disqualified the entire District Attorney’s office because of “the

unmistakable appearance of impropriety,” id. at 920, a rationale that is not a basis for

disqualifying government counsel under Pennsylvania’s ethics rules, see Harris, 460 A.2d

at 749; Miller, 422 A.2d at 529.

8

confidential information [she] learned” about Shah. App. 84-85. The trial AUSAs

confirmed that Miller “has not participated in the [Shah] case in any manner” nor

“divulged [to them] client confidences.” App. 87, 90. Based on these sworn statements,

the District Court did not clearly err in finding that Miller was screened from Shah’s

prosecution. Cf. Commonwealth v. Ford, 122 A.3d 414, 418 (Pa. Super. Ct. 2015)

(remanding where trial court disqualified the entire district attorney’s office because the

record did not indicate whether confidential information was disclosed or a “sufficient

fire wall ha[d] been . . . erected” and thus did not “support an exception to the general

rule, i.e., [did not support] disqualification of the entire [District Attorney’s] Office”).

Moreover, Shah has not shown that the ethical screen was ineffective. 6 In fact, he

concedes that he has no evidence that the denial of the disqualification motion prejudiced

him in any way. See Caggiano, 660 F.2d at 191 (reversing order disqualifying entire

USAO because, in part, “no prejudice has resulted to anyone in this case”). Instead, Shah

simply suggests that Miller was inevitably involved in his prosecution because of her

supervisory duties. In support, he cites the decision not to assign one of the trial AUSAs

additional cases to allow her to work on Shah’s case and the absence, in the AUSAs’

6

Shah asserts that the ethical screen was ineffective because the trial AUSAs

“found out” about Miller’s recusal from the docket, Appellant’s Br. at 16, but the

attorneys’ subjective understanding does not indicate that Miller did not satisfy her

ethical obligations to notify attorneys in the office. In addition, United States v. Schell,

775 F.2d 559 (4th Cir. 1985), does not help Shah. Unlike this case, in Schell, there was

some evidence suggesting that the side-switching AUSA disclosed his former client’s

confidences, and this led the court to question the effectiveness of the ethical screen

there. Id. at 566. There is no indication here that Miller had any discussions about Shah

with anyone.

9

affidavits, of information about who supervised them. Shah also relies on State v.

Tippecanoe County Court, 432 N.E.2d 1377, 1379 (Ind. 1982), in which the Indiana

Supreme Court concluded an entire district attorney’s office was properly disqualified

because the prosecutor had “administrative control over the entire staff.” Here, however,

there is no evidence that Miller exercised any control over the attorneys prosecuting

Shah. To the contrary, she swore that she did not “participate[] or cooperate[] in the

prosecution or supervision of [his] case,” App. 84, was never the direct supervisor of the

trial AUSAs, and would “not be involved in evaluating their performance in prosecuting

the Shah matter,” App. 85. Any decision Miller made regarding the AUSA’s other cases

has no bearing on Shah’s prosecution. Furthermore, Shah points to no requirement that

the USAO identify those who supervised the Shah prosecution in her stead, and he did

not rebut her sworn statement that someone else handled the supervisory duties in Shah’s

case.

Thus, the District Court did not abuse its discretion in denying Shah’s

disqualification motion. 7

2

The District Court also acted within its discretion in denying Shah’s motion for a

continuance on the first day of jury selection so that he could have an expert examine his

The District Court also acted within its discretion in declining to hold an

7

evidentiary hearing. While such a hearing may be useful in some cases, it is not required.

Goot, 894 F.2d at 237. Here, the Court had affidavits from Miller and the trial AUSAs

demonstrating an effective ethical screen was in place, and Shah presented nothing to

show that Miller played any role in his case or disclosed any information she learned

while representing him. See id.

10

patient files. Denial of a continuance “constitutes an abuse of discretion only when it is

‘so arbitrary as to violate due process.’” United States v. Kikumura, 947 F.2d 72, 78 (3d

Cir. 1991) (quoting Ungar v. Sarafite, 376 U.S. 575, 589 (1964)).

In this case, a continuance was not warranted. First, Shah had access to the files

since his 2016 indictment pursuant to Federal Rule of Criminal Procedure 16(a)(1)(E),

and his prior counsel acknowledged receipt of a notice providing that he could inspect

and copy all seized records. Moreover, Shah does not dispute that his counsel received at

least four letters in 2018 and 2019 reflecting that “[e]vidence gathered during the course

of the searches . . . is available for your inspection, upon request,” S. App. 101, and he

concedes that he did not ask for access before trial. 8 Second, Shah requested the

continuance at the start of trial without providing any explanation for the late request and

despite receiving other continuances. Cf. United States v. Irizarry, 341 F.3d 273, 305-06

(3d Cir. 2003) (denying continuance for discovery requested two weeks before trial

despite recent superseding indictment). Therefore, the District Court did not abuse its

discretion by denying the requested continuance. 9

8

To the extent Shah argues his counsel was ineffective in not requesting his

patient files earlier, such a claim is generally not cognizable on direct appeal. United

States v. Givan, 320 F.3d 452, 464 (3d Cir. 2003).

9

Moreover, Shah has not shown that he suffered any prejudice from the lack of

further discovery. Although he asserts that his patient files would reveal other symptoms

that could support angina diagnoses, trial testimony showed that his files contained false

information, he revised patient files before insurance reviews to “make them . . . sound

better,” App. 327, and regularly recorded angina diagnoses regardless of whether the

patient expressed chest pain—the defining characteristic of angina.

11

3 10

The District Court properly denied Shah’s motion for a judgment of acquittal on

Count Two. Count Two charged Shah with health care fraud by knowingly billing

insurers for ECP treatments using both the G0166 code and companion treatment codes

already encompassed by G0166. To convict Shah of health care fraud, the Government

was required to prove, among other things, that Shah acted with the intent to defraud the

insurers who provided medical benefits. United States ex rel. Doe v. Heart Solution,

P.C., 923 F.3d 308, 319 (3d Cir. 2019); 18 U.S.C. § 1347.

Viewing the record in the light most favorable to the Government, a reasonable

jury could have found Shah acted with intent to defraud. First, the evidence showed that

Shah knew that the G0166 code was not to be billed with codes for component treatments

on the same day. Second, the evidence demonstrated that Shah disregarded the billing

rules. Over his third-party billing service’s objection, Shah directed the service to

continue billing “[a]ll four codes.” App. 836. Although Shah argues that he eventually

stopped billing multiple codes—and told one insurer in 2011 that he instructed his billing

department to bill only G0166—a reasonable jury could find that, by instructing the third-

party billing service to continue billing using both code G0166 and the codes for the

companion treatments despite being told he should not, Shah acted with intent to defraud

10

We exercise plenary review over an order denying a motion for judgment of

acquittal, United States v. Smith, 294 F.3d 473, 477 (3d Cir. 2002), and view the record

“in the light most favorable to the prosecution,” United States v. Garner, 961 F.3d 264,

274 (3d Cir.), cert. denied, 141 S. Ct. 932 (2020).

12

insurers.

Because a reasonable jury could have found Shah knew the billing requirements

for ECP treatment and deliberately ignored them, the District Court properly denied his

motion for judgment of acquittal on Count Two.

B 11

Shah also argues that his sentence is both procedurally and substantively

unreasonable.

1 12

In reviewing the procedural reasonableness of a district court’s sentence, we focus

on, among other things, whether the district court correctly calculated the applicable

Guidelines range. United States v. Merced, 603 F.3d 203, 215 (3d Cir. 2010). Shah

disputes the District Court’s loss calculation, which triggered a sixteen-level increase to

his base offense level under U.S.S.G. § 2B1.1(b)(1)(I).

At the sentencing hearing, Special Agent Riordan testified that she examined

insurers’ data for claims involving ECP code G0166 together with the codes for the

companion treatments on the same day. Riordan totaled the average amounts reimbursed

11

“We review the factual determinations underlying a sentence for clear error.”

United States v. Douglas, 885 F.3d 145, 150 n.3 (3d Cir. 2018); see also United States v.

Brennan, 326 F.3d 176, 194 (3d Cir. 2003) (reviewing loss calculation for clear error).

12

A district court “need only make a reasonable estimate of the loss,” based on

available information in the record, United States v. Ali, 508 F.3d 136, 145 (3d Cir.

2007) (quoting U.S.S.G. § 2B1.1 cmt. 3(C)), and it “need not reach a precise figure,”

United States v. Tupone, 442 F.3d 145, 156 (3d Cir. 2006). “[T]he government bears the

burden of establishing, by a preponderance of the evidence, the amount of loss.” United

States v. Fumo, 655 F.3d 288, 310 (3d Cir. 2011).

13

by each insurer and endorsed a 50% reduction of that amount. Given evidence

suggesting that no ECP charges were legitimate, 13 Riordan testified that the 50%

reduction yielded a “conservative” estimate. App. 1469-70. The resulting loss

calculation was $2,959,550.00, with $1,296,502.00 coming from Medicare and Medicaid

plans.

Shah’s challenge to the loss calculation method fails. First, the average

reimbursements were based on the insurance claims data, and not Shah’s patient files as

he contends. Relying on the claims data was appropriate here given the evidence that

Shah’s patient files contained false information. Second, witness testimony about Shah’s

billing practices support the “reasonable estimate” of loss from Shah’s health care fraud

scheme. United States v. Kolodesh, 787 F.3d 224, 239-40 (3d Cir. 2015). Shah

instructed his third-party biller to continue billing “[a]ll four codes” despite insurers’

warnings against such billing. App. 836. In addition, insurers notified Shah that he

improperly submitted unbundled bills that were not substantiated by medical necessity.

Third, treating 50% of Shah’s ECP billing as legitimate is generous to Shah given the

“extensive and pervasive” nature of his scheme. See United States v. Hebron, 684 F.3d

554, 563 (5th Cir. 2012). Fourth, and relatedly, estimation was the only means to

calculate the loss. Shah’s records contained fraudulent information. Thus, they did not

13

Indeed, as the District Court observed in its discussion of the 50% reduction,

“the vast majority of the submitted claims under consideration were fraudulent” because

any of the following factors were present: (1) patient without a qualifying condition; (2)

records were “fraudulently created . . . after-the-fact;” (3) ECP treatment was

administered when a physician was not present; or (4) billing of unbundled codes without

justification. App. 48-49.

14

provide a reliable basis to determine if any of the ECP treatments were medically

necessary. See id. (affirming loss calculation because the defendant “should not reap the

benefits of a lower sentence because of his ability to defraud the government to such an

extent that an accurate loss calculation is not possible”); United States v. Miell, 661 F.3d

995, 1001 (8th Cir. 2011) (affirming loss calculation that subtracted average amount

defendant returned—rather than actual amount, due to practicality of reviewing over

2,500 files—because proceeds “were systemically tainted with fraud” such that “it was

difficult, if not impossible, to give [the defendant] any credit for parts of his claims that

might have been legitimate”). 14

For these reasons, Shah’s procedural challenge fails.

2

Shah’s sentence was also substantively reasonable as we cannot say that “no

reasonable sentencing court would have imposed the same sentence on that particular

defendant for the reasons the district court provided.” United States v. Tomko, 562 F.3d

558, 568 (3d Cir. 2009) (en banc). First, the sentence is within the applicable Guidelines

range of 78 to 97 months, U.S.S.G. § 5A, so we may presume that it is reasonable, Rita v.

United States, 551 U.S. 338, 347 (2007).

14

Shah cites United States v. Jones, 641 F.3d 706 (6th Cir. 2011), but that case is

distinguishable. Among other things, the Jones court called the extrapolation method

used there “into question” because it appeared the district court “[did not] even realize[]

that . . . fifty-four [of over 250] files were missing and . . . did not make a finding as to

whether they were fraudulent.” Jones, 641 F.3d at 712. Here, in contrast, the District

Court found that because Shah would “fraudulently create [patient] files after-the-fact

and solely for the benefit of receiving payment,” records that could establish which

treatments were fraudulent likely “did not exist.” App. 47-48.

15

Second, considering the totality of the circumstances, Tomko, 562 F.3d at 567,

Shah’s sentence was not greater than necessary given the seriousness of his offense and

the need for specific deterrence, 18 U.S.C. § 3553(a)(2)(A), (B). As to seriousness, Shah

billed insurers for millions of dollars in ECP treatments where they were either not

medically necessary for the patient or delivered without the required physician

supervision or both.

As to the need for specific deterrence, Shah twice failed to appear for his court

dates, leading the Court to issue arrest warrants. His failure to appear as required by

court order was consistent with his flagrant disregard for his obligations to his patients to

provide only medically necessary treatment and to follow the rules ensuring he was

reimbursed for only such services. His conduct reflects that he did not believe the rules

applied to him.

Because we cannot say that no reasonable sentencing court would have imposed

the same sentence, Shah’s substantive challenge fails.

III

For the foregoing reasons, we will affirm.

16
