Before WILLIAM PRYOR, Chief Judge, HULL and MARCUS, Circuit Judges.

HULL, Circuit Judge: 

After a jury trial, Arman Abovyan appeals his convictions and sentences for 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 1 of 51
2

conspiring to commit healthcare fraud, conspiring to possess with intent to 

dispense controlled substances, and seven counts of unlawfully dispensing a 

controlled substance. On appeal, he argues that insufficient evidence supported his

convictions, the jury instructions were improper, and his sentences were 

improperly calculated. After review, and with the benefit of oral argument, we 

affirm Abovyan’s convictions and sentences.

I. FACTUAL BACKGROUND

This healthcare fraud conspiracy was orchestrated by Kenneth Chatman, a 

convicted felon with no medical training. Chatman owned and operated two 

substance-abuse treatment centers, Reflections Treatment Center (“Reflections”) 

and Journey to Recovery (“Journey”), in South Florida.

1

 The Facilities offered

various levels of outpatient substance-abuse treatment for individuals suffering 

from drug and alcohol addiction, some of whom resided at separate “sober homes” 

and “halfway houses.”2

 

The defendant Arman Abovyan was a primary-care physician, boardcertified in internal medicine, with a private medical practice. Although Abovyan 

1

When we refer to Reflections and Journey collectively, we use the term “Facilities.” On 

paper, Chatman’s wife owned the Facilities because Chatman was a convicted felon. But in 

reality, Chatman was the true owner and operator. 

2

At trial, the terms “sober homes” and “halfway houses” were used for residences for 

patients attending outpatient drug treatment. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 2 of 51
3

had no prior experience in substance-abuse medicine, Chatman recruited him to be 

the medical director of the Facilities. 

In July 2016, Abovyan became medical director of Reflections and of

Journey when it opened in October 2016. As medical director, Abovyan’s duties 

included providing substance-abuse treatment, authorizing and ordering drug 

testing, and prescribing drug-treatment medication. Abovyan’s employment 

contract specified that he would work around 18.5 hours per week and be paid 

$11,000 per month. In practice, Abovyan was present at the Facilities only about 

nine hours per week or less. Abovyan remained the Facilities’ medical director 

until federal authorities executed search warrants and shut them down in December 

2016. Below, we describe the healthcare fraud scheme and Abovyan’s role in it. 

A. The Healthcare Fraud Scheme

Chatman’s healthcare fraud scheme involved over 20 individuals.

3

 Chatman

paid kickbacks to the owners of sober homes and halfway houses in exchange for 

them sending their patients to the Facilities for treatment and drug testing. 

For example, Anthony Jackson testified that he met Chatman around August 

3

Before Abovyan’s trial, Chatman pled guilty to conspiring to commit healthcare fraud, 

conspiring to commit money laundering, and conspiring to commit sex trafficking and was 

sentenced to imprisonment terms of 120 months on the healthcare fraud conspiracy, 240 months 

on the money laundering conspiracy, and 330 months on the sex trafficking conspiracy, all to run 

concurrent. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 3 of 51

2015, when Jackson owned a sober home.4 Most of Jackson’s residents had 

insurance. Chatman paid Jackson to send his sober home residents to attend 

Reflections for treatment and testing. Jackson later became program director at 

Reflections. 

Chatman required his employees at the Facilities to collect urine and saliva 

from their patients three times per week and send them for drug testing to specific 

toxicology labs, including Smart Lab and Ally Clinical Diagnostics (“Ally”). The 

labs charged thousands of dollars per specimen tested, for which the labs billed the 

Facilities’ patients’ insurance. In return, Chatman received kickbacks for sending 

specimens to Smart Lab and Ally for testing. 

For example, from the summer of 2016 until 2017, Bosco Vega was a sales 

representative for Smart Lab. Its CEO was Hawkeye Wayne. Vega testified that 

the more testing he procured for Smart Lab, the more he was paid in commissions

and the more kickbacks Chatman received. Vega had an arrangement with 

Chatman and Wayne, whereby Vega gave Chatman half of his net commissions as 

a kickback on all urine testing Reflections ordered from Smart Lab through Vega.5

 

During Vega’s time as a Smart Lab sales rep, he paid Chatman kickbacks of 

4

Before Abovyan’s trial, Jackson pled guilty to conspiring to commit healthcare fraud

and was sentenced to 42 months’ imprisonment. 

5

Before Abovyan’s trial, Vega pled guilty to money laundering but had not been 

sentenced. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 4 of 51
5

approximately $40,000 in cash. Vega also was paid between $10,000 and $20,000 

per month to “oversee[]” the organization and transportation of samples to Smart 

Lab. 

Similarly, Stefan Gatt worked for Ally as a medical sales representative. 

Gatt testified that, starting in February 2016, he paid Chatman kickbacks to use 

Ally for saliva testing.6

 Gatt was a partial owner of Journey with Chatman. Gatt 

admitted that he oversaw the urine and saliva testing that both Smart Lab and Ally 

provided for the Facilities’ patients. 

B. Abovyan’s Role in Ordering Tests

To help Chatman submit as many specimens as possible to Smart Lab and 

Ally, Abovyan ordered and authorized excessive lab drug testing that was

medically unnecessary. Abovyan’s predecessor at Reflections was Dr. Aron 

Tendler. Chatman fired Dr. Tendler after he attempted to curtail the excessive and 

medically unnecessary testing at Reflections. Chatman recruited Abovyan as 

Tendler’s replacement. 

When Abovyan started at Reflections, he wrote a letter adopting the testing 

regime that Dr. Tendler had unsuccessfully tried to curtail. The July 15, 2016, 

letter, typed on Reflections letterhead and signed by Abovyan, stated: 

6

Before Abovyan’s trial, Gatt pled guilty to conspiring to commit healthcare fraud and

finished serving his 18 months’ sentence. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 5 of 51
6

I am the new Medical Director for Reflections Treatment Center. Prior 

to my hire, [Dr. Tendler] left his post without reviewing and signing off 

on client charts. We have been unsuccessful in our attempts to reach 

him and rectify this situation. 

As a result, I have reviewed the orders and progress notes. I agree with 

the factual and medical recommendations of the previous Medical

Director. 

Abovyan then wrote “standing orders” authorizing the testing of the 

Facilities’ patients’ urine at least two to three times weekly. For example, one of 

these standing orders, titled “Urine Drug Test Protocol,” signed by Abovyan,

established that, for every patient, “Point of Care Cup testing will be used for rapid 

detection and the specimen will be sent to a separate lab for Confirmation.”7

 

Abovyan’s standing order authorized a laboratory testing frequency of “2-3 

Scheduled times per week and up to 2 random times per week” and stated that 

Abovyan “confirm[ed] that the Urine Drug Screening & Confirmation tests 

ordered by me are medically necessary for the diagnosis and treatment plan and 

will be documented in patients[’] chart[s] as medically necessary.” Based on that 

protocol, Abovyan signed consent forms authorizing Smart Lab “to perform the 

toxicology testing for patient specimens from [the Facilities] based off of the 

individual requisition forms.” 

7

There are different levels of urine testing. A “point of care” test is done in the office 

where the patient is getting care and involves an inexpensive cup and dipstick. Lab testing, also 

called “definitive or confirmatory testing,” is not done on-site, is expensive, and requires a 

doctor’s order. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 6 of 51
7

Facilities employees then used these requisition forms to order the lab drug 

tests for each individual specimen. The Facilities used different requisition forms 

depending on the type of specimen (urine or saliva) because they used Smart Lab 

for urine testing and Ally for saliva testing. The Smart Lab requisition forms had 

the Smart Lab logo at the top, a space for patient information, diagnosis codes, and 

a series of boxes to check to indicate which types of drugs the urine was to be 

tested for. Because Abovyan established standing orders and consent forms for 

Smart Lab testing, he did not sign each requisition form. Instead, Abovyan’s name 

was listed as the “Ordering Provider” on each form. 

Ally’s requisition forms were similar to Smart Lab’s, with an Ally logo at 

the top, a space for patient information, and drug-test-request checkboxes. Instead 

of establishing standing orders and consent forms like he did with Smart Lab, 

Abovyan pre-signed Ally’s testing requisition forms, leaving the patient 

information blank, but checking boxes for full comprehensive tests for all available 

drugs. 

Co-conspirator Gatt testified that Abovyan pre-signed Ally saliva testing 

requisition forms so that Gatt and others could make copies of them. Abovyan 

knew that they were photocopying his pre-signed requisition forms so that he “did 

not have to continually sign off on each individual form.” Gatt testified that either 

he or a staff member filled in the patient information and checked boxes for 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 7 of 51
8

various testing, and Abovyan knew about it because Gatt filled out one of the 

sheets in front of Abovyan and Abovyan signed it. 

These tests were not specialized to a named patient or a patient’s 

background. Rather, Abovyan admitted that he established this testing protocol

because that was “what Kenneth Chatman . . . wanted.” Even if a patient were

addicted only to cocaine, Abovyan admitted they would “test for everything.” In 

many instances, this meant that a lab tested specimens for over 100 substances, 

including drugs that would not meaningfully inform treatment because they were 

non-addictive or rarely abused. Each lab urine test costs between $1,000 and 

$6,000.

8

 

Patricia LaFrance, a Behavioral Health Technician, worked directly for 

Chatman at Reflections from July 2015 until around October 2016 and at Journey 

from October 2016 until the Facilities closed. LaFrance monitored patient 

urinalysis. LaFrance collected a cup of urine from every patient three times per 

week and performed a cup and dipstick test on every sample. Regardless of the 

cup test results, LaFrance sent the urine to the lab for further testing using lab

requisition forms that Abovyan authorized in his standing orders. Another 

employee trained LaFrance to fill out the Smart Lab requisition forms with the 

8

Most uninsured patients did not receive this expensive lab testing and were tested only 

once per month with an on-site cup/dipstick test that cost around $3. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 8 of 51
9

patient’s information and to check the appropriate boxes so that the lab tested the 

sample for a myriad of different drugs. 

When a patient did not show up for testing, various staff provided their own 

urine for lab analysis, at Chatman’s direction. LaFrance also collected saliva 

samples and filled out Abovyan’s pre-signed Ally requisition forms, which she 

gave to Gatt. 

C. Abovyan’s Role in “Treatment”

The Facilities also made money by billing patients’ insurance for outpatient

“treatment.” The Facilities’ treatment services included therapy sessions, medical 

checkups, and drug-treatment medication. In reality though, the patients received 

no real medical treatment. 

In addition to excessive drug testing orders, Abovyan prescribed Suboxone 

to his patients, even though he was not licensed to do so. Suboxone is a controlled 

substance that contains the Schedule III narcotic buprenorphine. The Drug 

Addiction Treatment Act of 2000 requires physicians who are not addiction 

specialists to take a training course and obtain a special license before they can 

prescribe buprenorphine for addiction treatment, in light of the drug’s potential for 

abuse and risk of side effects, including death. See 21 U.S.C. § 823(g). 

After completing a specialized training course and registering, doctors apply 

for a DEA certificate and receive an X Number, which allows them to lawfully 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 9 of 51
10

prescribe buprenorphine for addiction treatment. This special license, including 

the X Number, is not needed when buprenorphine is prescribed to treat other 

things, like pain. Until September 2016, Abovyan did not have an X Number. 

To get around the X Number requirement between July and September,

2016, Abovyan indicated on the Facilities’ patients’ buprenorphine prescriptions a 

diagnosis of “pain” or “withdrawal” (instead of drug addiction), even though 

patients’ charts did not indicate that they were, in fact, experiencing pain or 

withdrawal. 

Although ordering drug tests and prescribing buprenorphine, Abovyan often 

did so without actually examining patients, making assessments, or creating 

individualized treatment plans. Then, Abovyan rarely showed or discussed the lab

drug test results with patients. Although Abovyan noted in many patient charts, 

“[r]eviewed and will discuss at next patient encounter,” there was no such followup. Even when patients tested positive for drug use, there was no evidence in 

patients’ charts or elsewhere that Abovyan discussed this with patients or modified 

treatment. In some instances, Abovyan noted that a patient was “doing well” or 

“normal” or “clean for a while” even though the test results indicated otherwise. 

Despite being the Facilities’ main doctor, Abovyan largely delegated his 

treatment duties. He pre-signed prescription pads for his nurses to fill in the 

patient name, drug, and diagnosis without his being present. Jackson testified that 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 10 of 51
11

he saw Abovyan’s nurse practitioners with blank prescription pads signed by 

Abovyan. Abovyan also gave the nurses his log-in credentials to edit patients’ 

electronic medical records. When Abovyan did meet with the Facilities’ patients, 

it typically was for only around five minutes. Reflections even stored medications 

on site, and, if a patient was prescribed buprenorphine, Reflections would give the 

patient the medication from storage instead of waiting until the prescription was 

filled at the pharmacy. 

D. Federal Investigation

When the Facilities were shut down in December 2016, the Federal Bureau 

of Investigation (“FBI”) agents discovered Abovyan’s signature on stacks of Ally 

testing requisition forms. The test forms had no patient names or information but

did have diagnosis codes completed on the forms and boxes pre-checked to request 

full-panel lab testing. 

Agents also searched the storage unit of Tina Barbuto, the clinical director of 

Reflections and Abovyan’s codefendant. Agents found, inter alia, patient 

documents, test results, and pill bottles containing controlled substances, including 

Suboxone—which contains buprenorphine—that had been prescribed by Abovyan 

to the Facilities’ patients. Jackson testified he saw Barbuto with blank prescription 

pads signed by Abovyan. At Reflections, agents found a November 2016 letter 

directed to Abovyan from an insurance company, which stated that, “[d]ue to 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 11 of 51
12

ongoing and serious investigations regarding member safety and potential 

insurance fraud, we are temporarily suspending all approval of authorization for 

treatment at Reflections Treatment Center and payment of claims for any treatment 

at this facility.”

In April 2017, a UnitedHealthcare investigator interviewed Abovyan. 

Abovyan said that working at Reflections “was easy money,” but also the “biggest 

mistake of his life.” Abovyan admitted that he ordered the lab urine tests for 

patients at Reflections to be conducted two to three times per week. 

The FBI interviewed Abovyan in June 2017. Abovyan admitted that he: (1)

signed the standing lab orders; (2) ordered whatever lab tests that Chatman wanted 

three times per week per patient9

; (3) provided the nurse practitioners with presigned, blank prescription pads; and (4) received additional payments for detox and 

treatment services, and was paid $5,000 per month “so that Kenny Chatman could 

use [Abovyan’s] medical license to bill insurance.”10 

II. INDICTMENT & TRIAL

In 2018, a superseding indictment charged Abovyan and Tina Barbuto with: 

9

Abovyan told the FBI that he reviewed the lab test results for each patient and signed the 

electronic medical records indicating that he reviewed the results. However, at trial, patients and 

others testified that he did not review the test results with patients. 

10In some months, the $5,000 appears to be over and above his $11,000 salary, as the 

record shows that he was paid $19,000 in October and $17,300 in December 2016. In November 

2016, he was paid $15,300. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 12 of 51
13

conspiracy to commit healthcare fraud, in violation of 18 U.S.C. § 1349 (Count 

One); conspiracy to possess with intent to distribute and dispense controlled 

substances, including buprenorphine and others, in violation of 21 U.S.C. § 846 

(Count Two); unlawful dispensing of a controlled substance, buprenorphine, to 

specific patients (Counts Three through Nine), in violation of 21 U.S.C. 

§ 841(a)(1) and 18 U.S.C. § 2; and possession with intent to distribute controlled 

substances, in violation of § 841(a)(1) and § 2 (Count Ten). Codefendant Barbuto 

pled guilty to conspiracy to commit healthcare fraud. Chatman and around 15

others were already charged in separate indictments for their roles in the healthcare 

fraud scheme. 

During Abovyan’s eight-day jury trial, the government presented over 20

witnesses and overwhelming evidence of the above healthcare fraud scheme at the 

Facilities. Among the witnesses, the government called former employees of

Smart Lab, Ally, and the Facilities; nurse practitioners; an expert on addiction 

medicine; former Reflections patients; Abovyan’s private practice manager; the 

UnitedHealthcare investigator; and several FBI agents. Three witnesses, Jackson, 

Vega, and Gatt, were already convicted for their roles in the scheme. The evidence 

also included thousands of pages of patient records, supporting documents, and 

photographs. 

While the above evidence recounted Abovyan’s overall role in the scheme, 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 13 of 51
14

we now detail more testimony about Abovyan’s conduct.

A. Abovyan’s Two Nurse Practitioners

Andrea Buehler was a nurse practitioner who worked for Abovyan from 

September 2016 until January 2018. Buehler did office work for Abovyan’s 

private practice. Initially, Abovyan would have Buehler go to Reflections on 

Mondays and Wednesdays for around three hours each day. Sometimes Abovyan 

accompanied her, sometimes not. At first, Abovyan spent up to three hours with 

her there each day, but he was there less as time went on. Later on, Buehler went 

to Journey exclusively around twice per week; Abovyan accompanied Buehler to 

Journey only once or twice. 

For each patient at Reflections and later at Journey, Buehler discussed the 

patient’s drug use, did a physical examination, and sometimes wrote prescriptions. 

She never discussed drug test results with patients. Buehler wrote prescriptions for 

buprenorphine on pre-signed prescription pads, and Abovyan instructed her to 

write “drug dependence pain withdrawal” as the prescription diagnosis. She 

accessed patients’ electronic medical records with Abovyan’s log-in credentials. 

Lindsey Callaghan was a nurse practitioner who worked for Abovyan from 

around June until October 2016. For Abovyan’s private practice patients, 

Callaghan would see patients for routine physicals, sick visits, and medication 

refills. Callaghan went to Reflections on Tuesday and Thursday mornings for 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 14 of 51
15

around four hours each day. She refilled patients’ medications and performed 

quick physicals. Abovyan sometimes accompanied her to Reflections but did not 

always stay the entire time. Callaghan wrote prescriptions on a pre-signed 

prescription pad that Abovyan gave her. At Abovyan’s instruction, Callaghan 

wrote “Drug dependence, withdrawal, pain” as the diagnosis on the prescriptions. 

Generally, Callaghan did not review any drug test results. She also accessed 

patients’ electronic medical records with Abovyan’s log-in credentials. 

B. Patients’ Testimony

Patient A.B. was an insured Reflections patient addicted to heroin. She 

became a patient on August 31, 2016. A.B. stayed at a halfway house and attended 

therapy at Reflections. She said that, during group therapy sessions at Reflections, 

her fellow patients “were nodding out” and “obviously high.” A.B.’s fellow 

patients and even the managers of her halfway house were using drugs. A.B. 

witnessed Chatman give other patients “street drugs.” Although A.B. remained 

drug-free at first, she became desperate and started using heroin again. When she 

told Chatman that she was using heroin again, he said, “okay.” After that, A.B. 

overdosed on heroin at the halfway house. Another patient overdosed and died at

the halfway house. 

Reflections tested A.B.’s urine every day she attended Reflections. Yet 

neither Abovyan nor the nurse practitioners ever talked to her about the results. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 15 of 51
16

Even though A.B.’s urine tested positive for heroin, nothing about her treatment 

changed. Reflections also tested A.B.’s saliva, and she never saw the results. A.B. 

spoke to Abovyan only once for about 20 minutes during her initial visit. She 

received her prescriptions, including Suboxone, from a nurse practitioner written 

on pre-signed prescription pads. A.B. testified that the Suboxone “didn’t really 

help” her, but she continued to take it because “[she] knew [she] could get high off 

of it.” 

Patient H.F. was another insured Reflections patient starting in July 2016. 

She was prescribed Suboxone and subjected to rigorous blood, urine, saliva, and 

allergy testing, despite not having allergies. Her urine was lab tested about four 

times per week—a frequency that she felt “unnecessary to be able to catch 

someone using.” H.F. never saw the results of any tests. Chatman made it difficult 

for patients to leave treatment. When H.F. decided to leave, Chatman kept her 

identification, phone, clothes, and medication under his control. 

Patient J.B. was an insured patient at Reflections in 2016. J.B. saw Abovyan 

once, and Abovyan did not spend much time with her. Abovyan prescribed her 

three different anxiety medications. J.B. did not see Abovyan again, but she 

continued receiving prescriptions with Abovyan’s signature on them. J.B. saw presigned prescription pads bearing Abovyan’s signature on Chatman’s desk. J.B.

lived in a halfway house during her Reflections treatment and did not have to pay 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 16 of 51
17

rent. Her fellow Reflections patients in the halfway house were drinking and using

drugs, and, at one point, there were “needles everywhere.” One patient overdosed 

in the house. 

During his FBI interview, Abovyan explained his attitude about patients’ 

drug use after they left daily “treatment” at Reflections and returned to the halfway 

houses: “whatever happens happens.” 

C. Dr. Kelly Clark

The government called Dr. Kelly Clark as an expert witness. Dr. Clark, a 

board-certified physician in addiction medicine and psychiatry, is the President of 

the American Society of Addiction Medicine. Dr. Clark spent 100 hours reviewing 

patient files and other documents from the Facilities. She explained the legal 

requirements and best practices for addiction treatment centers and their medical 

duties, and how Abovyan failed to follow them. As to drug tests, Dr. Clark 

testified that: (1) drug testing always should be tailored to the patient, especially 

when ordering expensive confirmatory lab testing; (2) Abovyan improperly 

ordered across-the-board lab testing for every patient multiple times per week, 

every week; (3) a doctor “[a]bsolutely” should discuss the outcome of each test 

with the patient, particularly if they fail; and (4) there was no documentation in the 

charts that test results were ever discussed with the Facilities’ patients. 

As to prescriptions, Dr. Clark explained that: (1) Florida law does not allow 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 17 of 51
18

nurse practitioners to practice medicine without the supervision of a physician; (2) 

nurse practitioners may not write controlled substance prescriptions on a 

prescription pad that the doctor already has signed; (3) it is never appropriate for a 

doctor to sign blank prescriptions and give them to a staff member to fill in the 

patient name and drug; and (4) a doctor should not share his own log-in 

information for a patient’s medical record with others. 

As to buprenorphine, Abovyan improperly prescribed it without examining

the patient, having a doctor–patient relationship, or making an assessment and 

individualized treatment plan. Dr. Clark testified that: (1) Abovyan signed 

prescriptions for buprenorphine to treat “pain/withdrawal”; (2) there was no 

documentation in the charts that the patients, in fact, had pain or withdrawal; and 

(3) those prescriptions were written to treat opioid addiction—and not for a 

withdrawal period, but as ongoing management. 

Dr. Clark also testified that: (1) the amounts billed for urine testing were 

“outrageous”; (2) each lab test cost from over $1,000 to over $6,000 per urine 

specimen; (3) testing was done two to three times per week, with no patient followup; and (4) these tests thus were not used for treatment purposes. 

Dr. Clark discussed the buprenorphine prescriptions charged in Counts 

Three through Nine. The Reflections patient in Count Three was E.L., who had an 

opioid and cocaine addiction. On July 12, Reflections sent E.L.’s urine sample to 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 18 of 51
19

Smart Lab for an “extraordinarily high” 100-panel drug test that included drugs not 

ordinarily tested in the treatment or assessment of an addiction patient. On both 

July 13 and July 15, E.L.’s urine was extensively tested again. E.L.’s saliva was 

tested on July 14 and 28. Dr. Clark testified that “[t]here [was] no reason for doing 

both” saliva and urine tests simultaneously. 

On July 20, 2016, Abovyan prescribed E.L. Suboxone for “pain” and 

“withdrawal,” even though E.L.’s chart had no indication that he was experiencing 

pain or withdrawal or that Abovyan had seen him. Dr. Clark testified that the 

Suboxone prescription “was not for a legitimate medical purpose.” 

E.L.’s three July drug tests showed continued drug use. After E.L. stopped 

coming to Reflections, Abovyan electronically signed all three July test results

without any patient discussion. Yet, Abovyan added the note, “Reviewed and will 

discuss at next patient encounter.” There was no follow-up discussion. Dr. Clark 

testified that the manner in which the urine testing was performed—ordering 

additional tests before receiving the results of prior tests and not discussing those 

results with E.L.—was “[n]ot for a legitimate medical purpose.” This same pattern 

continued with the other patients. 

Counts Four and Eight involved Reflections patient H.F., who had cocaine, 

opioid, and alcohol addictions. H.F.’s urine was also tested by labs at an

“inappropriate” frequency: July 7, 8, 9, 11, 13, 15, 22, and 24. Although many 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 19 of 51
20

tests revealed continued drug abuse, Abovyan electronically signed them with his

standard notation, “Reviewed and will discuss at next patient encounter.” There 

was no follow-up discussion. 

On July 25, 2016, Abovyan prescribed H.F. Suboxone with a 

“pain/withdrawal” diagnosis (Count Four) and, a month later, on August 29, 

Abovyan again prescribed H.F. Suboxone for drug dependence, pain, and 

withdrawal (Count Eight). Dr. Clark explained that, because H.F.’s actual 

diagnosis was drug addiction, Abovyan could not have lawfully prescribed 

Suboxone without an X Number, which he did not have. 

Count Five involved Reflections patient A.C., who had an opioid addiction. 

A.C.’s urine was tested on June 15, 17, 20, 22, 27, and 29, and July 1, 4, 6, 11, 13, 

and 15, 2016. On July 27, Abovyan signed the results as “normal,” even though 

results showed tampering and drug abuse. On August 4, Abovyan wrote a progress 

note stating that A.C. was “clean for a while,” which plainly contradicted A.C.’s 

failed drug tests that Abovyan had reviewed and signed days earlier. On July 25, 

Abovyan prescribed A.C. Suboxone with a “pain/withdrawal” diagnosis. Again, 

Dr. Clark concluded that this Suboxone prescription was illegitimate because 

Abovyan falsely indicated that it was meant to treat “pain/withdrawal,” when it

was in fact treating drug addiction, and Abovyan did not yet have an X Number. 

Count Six involved Reflections patient D.W., who had a cocaine and opioid 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 20 of 51
21

addiction. The results of D.W.’s urine test on July 15, 2016, indicated tampering, 

yet Abovyan signed off on the results as “normal.” Abovyan’s progress notes 

stated that D.W. was “doing well,” even though he repeatedly failed drug tests. 

Although D.W. did not complain of pain, Abovyan prescribed Suboxone for 

“withdrawal/pain” on July 27, 2016.

Count Seven involved Reflections patient C.D., who came for an opioid 

addiction treatment from June until August 2016. C.D. provided urine specimens 

multiple times per week for expensive lab testing. Dr. Clark testified that the 

frequency of C.D.’s testing was “inappropriate” and lacked utility, that the money 

billed was “amazing,” and that the results were never discussed with the patient. 

Although C.D. did not complain of pain, Abovyan prescribed Suboxone for 

“pain/withdrawal” on August 3, 2016. In reality, Abovyan was prescribing the 

Suboxone for treatment of an opioid addiction, but he still did not have the 

required X Number. 

Count Nine involved Reflections patient A.B., who had no pain complaints. 

On August 31, Abovyan, without an X Number, prescribed A.B. Suboxone for

drug dependence, withdrawal, and pain. 

Dr. Clark explained that Abovyan pretextually prescribing Suboxone for 

“pain/withdrawal” without an X Number was only one of many factors underlying 

her opinion that Abovyan’s prescriptions were not for a legitimate medical 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 21 of 51
22

purpose. Dr. Clark explained that Suboxone is an excellent medication for use in 

treatment of an opioid disorder. But Abovyan was only prescribing controlled 

substances and was not treating his patients. Medical treatment requires assessing 

the information, working with the patient, coming up with a treatment plan for that 

patient, getting more information, following up on tests and reviewing them with 

the patient, assessing the additional information, and working more with the patient 

and the treatment plan. None of that occurred here. Abovyan’s patients repeatedly 

failed their drug tests, but he and his nurses never talked about it with them. 

“There was no treatment.” 

Dr. Clark also noticed that “scholarship” patients without insurance

generally would not receive a single expensive 100-panel lab test. Scholarship 

patients received a 12-panel cup/dipstick test once per month that cost a few 

dollars. 

At the close of the government’s evidence, Abovyan moved for judgment of 

acquittal under Federal Rule of Criminal Procedure 29, which the district court

denied as to Counts One through Nine and reserved ruling as to Count Ten. 

D. Defense and Verdict

Abovyan’s defense was that he was an “unwitting patsy,” who was used by 

Chatman and others for their criminal scheme. Abovyan did not testify, but 

presented an expert witness, Dr. Kenneth Starr, who is a board-certified physician 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 22 of 51
23

in emergency and addiction medicine. Dr. Starr spent “[m]aybe six” hours 

preparing for the case and did not review any patient files. Dr. Starr confirmed that 

buprenorphine may be prescribed for pain without an X Number, but that the 

X Number is required for use in addiction treatment. Dr. Starr admitted that it was 

not a common practice to pre-sign blank prescriptions, and that the drugs found in 

some of Abovyan’s patients’ test results would be something that he would want to

discuss with the patients. At the close of evidence, Abovyan renewed his Rule 29 

motion, and the district court maintained its earlier ruling. 

In closing argument, Abovyan’s counsel acknowledged that “[Gatt] and 

Kenny Chatman essentially conspired . . . to defraud the insurance companies,” 

and LaFrance “dummied up these [requisition] forms.” But he argued that 

“Abovyan had no knowledge” about excessive urine testing. The jury convicted 

Abovyan on Counts One through Nine and acquitted him on Count Ten. The 

district court denied Abovyan’s motion for judgment notwithstanding the verdict 

or for a new trial. 

The district court sentenced Abovyan to 120 months’ imprisonment on his 

Counts One through Eight convictions, to run concurrently, and a consecutive 

15-month sentence on his Count Nine conviction. The district court ordered 

$1,058,097.88 in restitution to the defrauded insurance companies.

24

III. SUFFICIENCY OF THE EVIDENCE

On appeal, Abovyan argues that the government’s evidence is insufficient to 

support his convictions. We review de novo Abovyan’s sufficiency-of-theevidence claims, taking all evidence and drawing all reasonable inferences in the 

light most favorable to the government. United States v. Chalker, 966 F.3d 1177, 

1184 (11th Cir. 2020). 

A. Conspiracy to Commit Healthcare Fraud (Count One)

Abovyan accepts that the healthcare fraud conspiracy existed at the 

Facilities, but contends the government’s evidence was insufficient to prove his 

knowledge of and participation in it. At most, he argues, the government showed 

negligent medical practices on his part, not willful participation in a criminal 

conspiracy. He asserts that there is not “a shred of evidence” that he agreed with 

anyone to engage in healthcare fraud and that “the [g]overnment still has not 

identified a single text, email, document, or snippet of testimony that there was 

ever any conversation or communication between Abovyan and any other person 

about engaging in any illegal act.” 

“For a defendant to be found guilty of conspiracy, the government must 

prove beyond a reasonable doubt (1) that a conspiracy existed; (2) that the 

defendant knew of it; and (3) that the defendant, with knowledge, voluntarily 

joined it.” United States v. Vernon, 723 F.3d 1234, 1273 (11th Cir. 2013) 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 24 of 51
25

(quotation marks omitted). “Because the crime of conspiracy is predominantly 

mental in composition, it is frequently necessary to resort to circumstantial 

evidence to prove its elements.” United States v. Toler, 144 F.3d 1423, 1426 (11th 

Cir. 1998) (quotation marks and citations omitted). 

A healthcare fraud conspiracy exists when defendants agree to submit false 

claims to a healthcare benefit program, such as an insurance plan. See United 

States v. Ruan, 966 F.3d 1101, 1142 (11th Cir. 2020); 18 U.S.C. §§ 24(b), 1347. 

“[A] defendant can be convicted of conspiracy if the evidence demonstrates that he 

was aware of the conspiracy’s essential nature, even if he did not know all of its 

details, played only a minor role in the overall scheme, did not have direct contact 

with other alleged co-conspirators, or did not participate in every stage of the 

conspiracy.” United States v. Sosa, 777 F.3d 1279, 1290 (11th Cir. 2015).

First, we reject Abovyan’s claim that the government must present direct 

evidence that Abovyan agreed to join the conspiracy. It is well settled that the 

government may prove a conspiracy through circumstantial evidence or inferences 

from the defendant’s conduct. See United States v. Moran, 778 F.3d 942, 960 

(11th Cir. 2015); United States v. Molina, 443 F.3d 824, 828 (11th Cir. 2006). The 

government can show participation “through proof of surrounding circumstances 

such as acts committed by the defendant which furthered the purpose of the 

conspiracy.” Moran, 778 F.3d at 961 (quotation marks omitted).

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 25 of 51
26

Second, although largely circumstantial, the government introduced ample

evidence to support Abovyan’s conviction for conspiring to commit healthcare 

fraud. The evidence showed that Abovyan: (1) created Smart Lab standing orders 

so that the Facilities could order expensive and medically unnecessary lab urine 

tests three times per week per patient; (2) pre-signed requisition forms so that the 

Facilities could order even more unnecessary testing from other labs, like Ally; 

(3) forwent lab testing for uninsured patients; (4) reviewed and signed off on

certain lab test results without discussing them with the patients; (5) admitted the 

Facilities would “test for everything,” even non-addictive drugs not ordinarily 

tested in addiction treatment; (6) provided his medical record log-in and pre-signed 

prescription pads for his nurses to prescribe drugs to patients without him being 

present; (7) received a letter alerting him that insurance billing issues existed and 

did nothing; (8) admitted that he allowed Chatman to make all testing decisions—

“what [Chatman] wanted”—even though Chatman had no medical training and the 

testing was excessive; and (9) admitted that he received $5,000 per month for 

Chatman to use his medical license to bill insurance for “treatment” at the 

Facilities. 

Abovyan’s full cooperation with Chatman, along with Abovyan’s own 

medical conduct, advanced the healthcare fraud scheme. The government proved 

Abovyan not only agreed to join the conspiracy but also willfully participated in it

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 26 of 51
27

and knew of its essential nature. See Ruan, 966 F.3d at 1143–44 (finding sufficient 

evidence of conspiracy to commit healthcare fraud where defendant doctors

(1) ordered “expensive off-site urine screen tests that were medically unnecessary,” 

and (2) “rarely discussed inconsistent test results with patients, whether to counsel 

them into compliance or fire them as patients”); see also United States v. Mateos, 

623 F.3d 1350, 1362 (11th Cir. 2010) (“While it is hypothetically possible that a 

person under these circumstances could have been ignorant of the [conspiracy to 

commit healthcare] fraud, the jury was entitled to draw the reasonable inference 

from this evidence that [the defendant] was in on the scheme.”). 

Abovyan relies on United States v. Willner, 795 F.3d 1297 (11th Cir. 2015),

and United States v. Ganji, 880 F.3d 760 (5th Cir. 2018), which reversed

healthcare fraud conspiracy convictions. The evidence against Abovyan, however, 

is substantially stronger and materially different than in these cases. 

In Willner, we reversed Dr. Abreu’s conviction, despite her being the 

program director at a sleep clinic that defrauded Medicare. 795 F.3d at 1303, 

1305–10. The government contended that Dr. Abreu (1) “falsified patient files” to 

make it appear that patients were eligible for the clinic’s partial hospitalization 

program, and (2) “admitted or participated in the admission of ineligible patients”

into the program. Id. at 1306, 1309. Although Dr. Abreu admitted some ineligible 

patients (cognitively impaired, elderly patients), no evidence showed that it was 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 27 of 51
28

anything more than “poor admission decisions on occasion.” Id. at 1309. Unlike 

Abovyan, Dr. Abreu did not gain anything from the criminal conspiracy. Id. at 

1310. While Dr. Abreu knew Dr. Gumer was signing charts without reading them, 

this Court explained that this evidence about chart signing “does not support an 

inference that Dr. Abreu knew that the patients were ineligible, that they had not 

received partial hospitalization services, or that Dr. Gumer had not treated the 

patients.” Id. at 1309. The government’s circumstantial evidence against 

Dr. Abreu was weak, and her conduct was isolated and peripheral at best. It pales

compared to the overwhelming evidence showing Abovyan’s role and conduct that 

was central to the criminal conspiracy and its success, his consistent and ongoing 

participation in the scheme throughout his tenure as medical director, and his 

significant financial gains from the scheme.

Similarly, in Ganji, the Fifth Circuit reversed the healthcare fraud conspiracy 

conviction of a physician serving as the medical director of a home healthcare 

agency. 880 F.3d at 763–64. The evidence was only that: (1) another doctor, 

Dr. Winston Murray, who previously held a similar position, defrauded Medicare; 

(2) when Dr. Ganji accepted the job, she received a monthly check of $1,000; and 

(3) Dr. Ganji’s referral of patients to the agency increased after she became 

medical director. Id. at 771. No evidence supported any inference that Dr. Ganji 

acted in the same fraudulent manner as Dr. Murray. Id. Dr. Ganji’s increase in 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 28 of 51
29

referrals was not nefarious; rather, her patients simply followed her when she 

became affiliated with the home healthcare agency. Id. at 773. And Dr. Ganji

“provided testimony of her innocence that went unanswered by the [g]overnment,”

including her explanation that certain blank sheets she signed were bundled with 

other documents she reviewed. Id. at 771. The Fifth Circuit emphasized that 

“[t]he trial record rebut[ted] the [g]overnment’s theory.” Id. at 772.

Again, in stark contrast, the government’s evidence here was powerful and 

showed Abovyan’s key role, conduct, and participation in the healthcare fraud 

scheme. Abovyan knew he pre-signed all the prescription pads, signed the 

standing orders for excessive lab testing, was not seeing or following up with 

patients at the Facilities, was not doing or revising individualized treatment plans, 

gave his log-in credentials to his nurses, and did not have the required training and 

X Number to prescribe Suboxone. Abovyan even admitted that he was paid “easy 

money” for “Chatman [to] use [Abovyan’s] medical license to bill insurance.” 

Given our extensive record review recounted above, we readily conclude that the 

government’s evidence sufficiently supported Abovyan’s conviction for conspiracy 

to commit healthcare fraud.

B. The Controlled Substances Act Counts (Counts Two through Nine)

Counts Two through Nine involve the conspiracy and substantive counts as 

to the buprenorphine prescriptions. Abovyan argues that the government failed to 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 29 of 51
30

prove his buprenorphine prescriptions were not for a legitimate medical purpose or 

were outside the scope of professional practice. 

Under the Controlled Substances Act, it is unlawful, except as otherwise 

authorized, “for any person knowingly or intentionally . . . to manufacture, 

distribute, or dispense . . . a controlled substance.” 21 U.S.C. § 841(a)(1); see also

21 U.S.C. § 846 (making it unlawful to conspire to violate § 841). An unlawful 

distribution occurs in the medical context when “1) the prescription was not for a 

legitimate medical purpose or 2) the prescription was not made in the usual course 

of professional practice.” United States v. Joseph, 709 F.3d 1082, 1102 (11th Cir. 

2013) (quotation marks omitted). The rule is disjunctive, and a doctor violates the 

law if he falls short of either requirement. See Ruan, 966 F.3d at 1172. “The 

appropriate focus is not on the subjective intent of the doctor, but rather it rests 

upon whether the physician prescribes medicine in accordance with a standard of 

medical practice generally recognized and accepted in the United States.” United 

States v. Merrill, 513 F.3d 1293, 1306 (11th Cir. 2008) (quotation marks omitted). 

Here, Abovyan violated 21 U.S.C. § 823(g) when he prescribed 

buprenorphine without an X Number. See 21 U.S.C. § 823(g)(2)(E)(i). We agree 

with Abovyan that this is not a per se violation of § 841(a), and, more importantly, 

this alone does not support a § 841(a) conviction. However, as Dr. Clark testified, 

Abovyan’s lack of an X Number was not the only problem with his buprenorphine 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 30 of 51
31

prescriptions. Abovyan prescribed buprenorphine for pain/withdrawal when 

patients did not have pain/withdrawal. Further, he provided no medical addiction 

treatment and, without accompanying treatment, Abovyan’s buprenorphine 

prescriptions did not serve a legitimate medical purpose. 

Dr. Clark explained that buprenorphine can be a very effective drug when 

used in addiction treatment, but she unequivocally stated that Abovyan’s patients 

were not actually being treated. Prescribing buprenorphine to drug addicts without 

more is not medical treatment. Viewing the evidence in the light most favorable to 

the government, Abovyan prescribed buprenorphine after conducting no physical 

examinations or only a cursory physical examination, having no doctor–patient 

relationship, and making no assessment or treatment plan. Abovyan generally

delegated the prescribing of buprenorphine to his nurse practitioners,

inappropriately giving them blank prescription pads and access to his log-in 

credentials for patients’ electronic medical records. When many patients he was

supposedly “treating” with buprenorphine failed subsequent drug tests, he did 

nothing. Patients rarely even saw their test results. Dr. Clark testified that 

Abovyan’s use of buprenorphine deviated from professional standards of medical 

addiction treatment, and the prescriptions were “not for a legitimate medical 

purpose.” 

Thus, setting aside the X Number issue, Abovyan either prescribed 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 31 of 51
32

buprenorphine for “pain/withdrawal” to patients who were not experiencing pain

or withdrawal, or he prescribed it to “treat addiction” without actually treating 

addiction. Either way, under the particular circumstances here, the prescriptions 

did not serve a legitimate medical purpose and were not done in the usual course of 

professional practice. 

Our decision in United States v. Joseph, 709 F.3d 1082, is instructive. In 

Joseph, Spurgeon Green Jr., a physician, and Dorothy Mack, a physician’s 

assistant, were convicted under § 841(a). Id. at 1087–88. They conceded their

federal-regulation violation by not properly dating and signing the prescriptions. 

Id. at 1102. Mack admitted that she, as a physician’s assistant, lacked the authority 

to write prescriptions for Schedule II substances under Georgia law. Id. This 

Court agreed that their violation of the federal regulation did not constitute a per se

violation of § 841(a). Id. Nonetheless, “the jury was entitled to infer, based on 

Green’s pre-signing and pre-dating of the prescriptions and Mack’s delivery of 

those prescriptions to Green’s patients, that they violated [§ 841(a)].” Id. We 

observed that “a physician’s delivery of a prescription without conducting any 

physical examination of the patient provides strong evidence to support a 

conviction under [§ 841(a)].” Id. 

Here, Abovyan violated federal law by prescribing a drug, buprenorphine, 

without the required training, licensing, and X Number. Although this does not 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 32 of 51
33

constitute a per se violation of § 841(a), “the jury was entitled to infer” that 

Abovyan violated § 841(a) based on all of his conduct described above, including 

how Abovyan was not actually treating his patients for their addiction. See id. 

We also reject Abovyan’s claim that the prescriptions, nonetheless, served a 

legitimate medical purpose because “these patients were addicts who needed [the] 

buprenorphine that Dr. Abovyan prescribed.” The question is not whether a doctor 

could prescribe buprenorphine for legitimate medical addiction treatment actually 

being rendered, but whether Abovyan himself did prescribe buprenorphine for such 

actual addiction treatment. Based on the cumulative evidence about the patients 

and these prescriptions, a jury could reasonably find that Abovyan was not legally 

prescribing buprenorphine, especially given that the addicts were not being treated, 

were failing drug tests, were not in withdrawal or pain, and were not being seen by 

him.

11 Therefore, we conclude sufficient evidence supported Abovyan’s 

convictions on Counts Two through Nine.

12 

11For example, the jury could infer from the evidence that Abovyan’s buprenorphine 

prescriptions were intended mainly as window-dressing so that the Facilities appeared to be 

providing drug “treatment” when their real purpose was to conduct expensive and unnecessary 

tests on the patients that could be billed to their insurance.

12To the extent Abovyan argues that he did not know about or join a conspiracy to 

unlawfully dispense buprenorphine (Count Two), his argument fails for the same reasons it fails 

as to the conspiracy element in Count One. Abovyan’s prescribing of buprenorphine was part of 

the overall healthcare fraud scheme that Abovyan knew about and joined. Chatman told 

Abovyan that he should prescribe buprenorphine; the prescriptions were part of the purported

“treatment” that the Facilities billed to insurance but were not really providing. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 33 of 51
34

IV. JURY INSTRUCTIONS

Abovyan also challenges various jury instructions, which we discuss in turn. 

A. Instructions as to Count One

On appeal, Abovyan argues for the first time that the district court plainly 

erred in failing to instruct the jury on the elements of substantive healthcare fraud, 

which was the object of the healthcare fraud conspiracy charge in Count One. 

Abovyan did not object to this omission in the instructions, and plain-error review 

applies. See United States v. Benjamin, 958 F.3d 1124, 1133 (11th Cir.), cert. 

denied, __ U.S. __, 141 S. Ct. 561 (2020).13

The district court adequately instructed the jury as to the elements of a 

criminal conspiracy and that its object was healthcare fraud. For example, the 

district court instructed that the jury had to find Abovyan “agreed to try to 

accomplish a common and unlawful plan to commit health care fraud, as charged 

in the superseding indictment” and that, knowing “the unlawful purpose of the 

plan,” he “willfully joined in it.” In turn, the unlawful purpose of the conspiracy, 

as described in the superseding indictment, was that Abovyan conspired to: “(a) 

defraud health care benefit programs . . . ; and (b) obtain, by means of materially 

13Plain error requires (1) error, (2) that is plain, and (3) that affects substantial rights. 

Benjamin, 958 F.3d at 1133. But even if all these elements exist, this Court may exercise its 

discretion to correct the error only if such error seriously affects the fairness, integrity, or public 

reputation of the judicial proceedings. Id. We reject the government’s contention that defense 

counsel invited the error. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 34 of 51
35

false and fraudulent pretenses, representations, and promises, any of the money 

and property owned by, and under the custody and control of, health care benefit 

programs . . . .” Superseding Indictment at 9 (emphasis added). The district court,

itself, however, did not expressly instruct the jury as to the elements of a healthcare 

fraud offense. 

The Supreme Court has explained that “an instruction that omits an element 

of the offense does not necessarily render a criminal trial fundamentally unfair or 

an unreliable vehicle for determining guilt or innocence.” Neder v. United States, 

527 U.S. 1, 9, 119 S. Ct. 1827, 1833 (1999). Although such an omission may 

constitute plain error, that is not always the case. See United States v. Musgrave, 

444 F.2d 755, 764 (5th Cir. 1971) (“[T]he trial judge’s failure here to instruct the 

jury on all the essential elements of the crimes in counts two and four, even though 

not requested, [is] plain error.”)14; United States v. Hensel, 711 F.2d 1000, 1005 

(11th Cir. 1983) (“Musgrave does not hold that every failure to charge on all the 

essential elements of the crime results in plain error.”).

In United States v. Gonzalez, the defendant argued that the district court 

plainly erred by failing to instruct the jury on the elements required to prove a 

violation of the federal anti-kickback statute, which was one of the objects of the 

14In Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir. 1981) (en banc), this 

Court adopted as precedent the decisions of the former Fifth Circuit handed down prior to 

October 1, 1981. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 35 of 51
36

conspiracy. 834 F.3d 1206, 1225 (11th Cir. 2016). We held that the failure to 

explain the term “kickback” was not “a clear or obvious error.” Id. One reason 

was because “the indictment essentially quoted the entire relevant portion of the 

anti-kickback statute.” Id. at 1226.

Similarly, here the district court referred to an “unlawful plan to commit 

health care fraud, as charged in the superseding indictment.” The jury had a 

redacted copy of the superseding indictment, which incorporated the statutory 

elements of healthcare fraud into the conspiracy charge. See 18 U.S.C. § 1347(a). 

The superseding indictment described healthcare fraud as a scheme to both

“(a) defraud health care benefit programs . . . ; and (b) obtain, by means of 

materially false and fraudulent pretenses . . . any of the money and property owned 

by . . . health care benefit programs,” which tracks almost verbatim the language of 

18 U.S.C. § 1347(a)(1) and (2). Superseding Indictment at 9 (emphasis added). If 

anything, the description in the superseding indictment required more than the 

statute, which only requires proof of one of those two elements. See 18 U.S.C. 

§ 1347(a)(1)–(2).

Moreover, in this particular case, there was no dispute that there was a 

healthcare fraud conspiracy and its object—healthcare fraud—did occur. Even if it 

was plain error, the omission of the elements of healthcare fraud from the 

instructions did not affect Abovyan’s substantial rights. See Benjamin, 958 F.3d at

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 36 of 51
37

1133. Abovyan’s theory of defense acknowledged that there was a healthcare 

fraud scheme but asserted that he was merely an “unwitting patsy.” By the time of 

Abovyan’s trial, numerous people were already convicted for their involvement in 

Chatman’s healthcare fraud scheme at the Facilities, and three of them testified in 

Abovyan’s trial. Abovyan argued solely that he was unaware of any conspiracy 

and did not agree to join it. Under the actual circumstances of this case, any error 

in failing to explain the elements of the substantive healthcare fraud did not affect 

Abovyan’s substantial rights, given the jury charge, the superseding indictment, 

and that all parties agreed the substantive offense had been committed by others at 

the Facilities. See Gonzalez, 834 F.3d at 1225 (“[I]n reviewing jury instructions, 

our task is also to view the charge itself as part of the whole trial.” (quotation 

marks omitted)). 

B. Denial of Abovyan’s Requested Instruction

Next, Abovyan argues that, as to Counts Two through Nine, the district court 

abused its discretion by declining to give his requested instruction on the 

difference between criminal and civil liability. We review for an abuse of 

discretion a refusal of the district court to give a requested jury instruction. Joseph, 

709 F.3d at 1093. “When we review the refusal to give an instruction for abuse of 

discretion, we ask whether the requested instruction is correct, not adequately 

covered by the charge given, and involves a point so important that failure to give 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 37 of 51
38

the instruction seriously impaired the party’s ability to present an effective case.” 

United States v. Duperval, 777 F.3d 1324, 1334 (11th Cir. 2015) (quotation marks 

omitted).

The district court did not abuse its discretion in refusing to give Abovyan’s 

requested instruction because it was not a correct statement of the law. Abovyan’s 

proposed instruction stated, among other things: “the [g]overnment must prove 

beyond a reasonable doubt that Dr. Abovyan was not acting as a doctor but as a 

drug dealer,” that “[t]he essential issue for your determination is whether 

Dr. Abovyan acted not as a doctor, or even as a bad doctor, but as a ‘pusher,’” and 

that he was engaged in criminal activity, like “knowingly selling narcotics to a 

‘patient’ who was not really sick but wanted drugs for recreational purposes.” 

Contrary to Abovyan’s proposed instruction, and as explained above, the law 

requires only that the jury find the doctor prescribed a drug “not for a legitimate 

medical purpose” or not “in the usual course of professional practice.” See Ruan, 

966 F.3d at 1136 (quotation marks omitted). The district court properly declined to 

give Abovyan’s proposed instruction.

C. Instructions as to X Number

Abovyan also argues that the instructions created strict § 841(a) liability for 

the violation of § 823(g), which contains the licensing requirement for an

X Number. We review de novo whether a given jury instruction misstated the law.

United States v. Melgen, 967 F.3d 1250, 1259 (11th Cir. 2020). “[W]e will reverse 

a conviction due to an erroneous jury instruction only when ‘the issues of law were 

presented inaccurately, or the charge improperly guided the jury in such a 

substantial way as to violate due process.’” Gonzalez, 834 F.3d at 1222 (quoting 

United States v. Williams, 526 F.3d 1312, 1320 (11th Cir. 2008)). “We must have 

‘a substantial and ineradicable doubt as to whether the jury was properly guided in 

its deliberations’ before reversing a conviction on a challenge to the jury charge.” 

United States v. Joyner, 882 F.3d 1369, 1375 (11th Cir. 2018) (quoting United 

States v. House, 684 F.3d 1173, 1196 (11th Cir. 2012)).

The jury instructions accurately stated the law. First, the district court 

correctly described the elements of a § 841(a) violation. The district court 

explained that Abovyan was guilty under § 841(a) if the government proved 

beyond a reasonable doubt that he “dispensed . . . not for a legitimate medical 

purpose or outside the usual course of professional practice, the controlled 

substance, as charged.” The instructions charged that § 841(a) has a mens rea of 

“knowingly and intentionally” and that Abovyan cannot “knowingly” do 

something “because of a mistake or by accident.” 

Second, appearing to reference 21 C.F.R. § 1306.05, the district court 

properly instructed that prescriptions must “be dated as of, and signed on, the day 

when issued” and that “the prescribing practitioner is responsible in case the 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 39 of 51
40

prescription does not conform in all essential aspects to the law and regulations.” 

Third, the district court precisely recited the X Number requirement in 

§ 823(g), the process to obtain it, and the consequences for non-compliance, as 

follows:

[I]n order to prescribe buprenorphine for detoxification and 

maintenance treatment, a practitioner is required to obtain a waiver 

under the Drug Addiction Treatment Act of 2000. The practitioner 

must apply to the Substance Abuse and Mental Health Services 

Administration (“SAMHSA”), under the Secretary of Health and 

Human Services, who verifies that the practitioner meets the 

requirements, including completion of not less than eight hours of a 

qualified training course by the physician. After SAMHSA notifies the 

Drug Enforcement Administration (“DEA”) that the requirements have 

been met, DEA then assigns the practitioner a special registration 

number, known as a “DEA X-number.” If a practitioner is in violation 

of these conditions and dispenses buprenorphine for maintenance 

treatment or detoxification treatment, the Attorney General may 

consider the practitioner to have committed an act that renders the 

registration of the practitioner pursuant to subsection (f) to be 

inconsistent with the public interest.

A prescription for buprenorphine for “detoxification treatment” 

or “maintenance treatment” must include the practitioner’s DEA Xnumber. 

Fourth, the instructions well explained “the usual course of professional 

practice,” as follows:

A controlled substance is prescribed by a physician in the usual course 

of professional practice and, therefore, lawfully, if the substance is 

prescribed by him as part of his or her medical treatment for the patient 

in accordance with the standards of medical practice generally 

recognized and accepted in the United States. The appropriate standard 

of care is based on the knowledge, circumstances and standards that are 

recognized as acceptable and appropriate at the time the physician 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 40 of 51
41

acted. The fact that bad results follow treatment rendered by a 

physician does not, in itself, mean that the physician’s conduct fell 

below the appropriate standard of care. 

Finally, the instructions rightly reiterated that, to convict Abovyan for 

violating § 841(a), the government had to prove that his “actions were not for 

legitimate medical purposes or were outside the usual course of professional 

practice.” 

At no point did the district court instruct the jury that a violation of the 

X Number-licensing requirement necessitated a finding of guilt on Counts Two 

through Nine. As discussed above, we agree that a violation of § 823(g) is not a 

per se violation of § 841(a). And the district court here did not instruct the jury 

that it was. We thus conclude that these instructions, considered as a whole, did 

not create strict § 841(a) liability for the violation of the X Number license 

requirement.15 Because the issues of law were presented accurately to the jury, 

there was no error.

16 See Gonzalez, 834 F.3d at 1222. 

15We recognize that, at the charge conference, the district court and the government made 

some statements that seemed to suggest Abovyan’s alleged violation of § 823(g) made him 

“strict[ly] liab[le]” under § 841(a). But the instructions themselves did not charge that. Further, 

to the extent that Abovyan contends that the refusal to give his requested instruction, combined 

with the above instructions actually given, resulted in reversible error, we disagree because the 

district court did not err in either instance. 

16Abovyan also challenges two evidentiary rulings during his trial. He claims that the 

district court abused its discretion in admitting evidence of Abovyan’s gambling hobby and in 

improperly limiting cross-examination of the government’s case agent. We conclude that these 

claims wholly lack merit and do not warrant further discussion.

V. SENTENCES

Abovyan also challenges his sentences. We review how the district court 

calculated Abovyan’s advisory guidelines range and then his claims on appeal.

A. Guidelines Calculation

The presentence investigation report (“PSI”) determined that, during 

Abovyan’s five-month employment at Reflections, 42 insurers were billed a total 

of $11,345,741.55, from which Reflections received $1,058,097.88 in 

reimbursements, and Abovyan was responsible for the intended loss of 

$11,345,741.55. 

For Count One, the PSI calculated an offense level of 32, consisting of: (1) a 

base offense level of 6, under U.S.S.G. § 2B1.1(a)(2); (2) a 20-level increase based 

on an intended loss of between $9.5 million and $25 million, under 

§ 2B1.1(b)(1)(K); (3) a 2-level increase because the offense involved more than ten 

victims, under § 2B1.1(b)(2)(A); (4) a 2-level increase, under § 3A1.1(b)(1), 

because Abovyan knew or should have known the victims were vulnerable; and (5)

a 2-level increase, under § 3B1.3, because Abovyan used his skill as a medical 

doctor to facilitate the offense. 

For Counts Two through Nine, the PSI used the base offense level of 24 

because the offense involved a drug equivalency of between 100 and 400 

kilograms of marijuana. See U.S.S.G. § 2D1.1(a)(5) and (c)(8). 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 42 of 51
43

After making the multiple-count adjustment under § 3D1.4(a)–(c), the PSI 

recommended a combined adjusted offense level of 33. Based on an offense level 

of 33 and a criminal history category of I, Abovyan’s advisory guidelines range 

was 135 to 168 months’ imprisonment. 

Abovyan objected to the PSI’s use of intended loss, instead of actual loss, to 

calculate his advisory guidelines range. He acknowledged that the Sentencing 

Guidelines define loss as the greater of actual or intended loss. See U.S.S.G. 

§ 2B1.1 cmt. n.3(A). Here, the amount that Abovyan helped the Facilities and labs 

bill to the insurance companies was approximately $11.3 million (intended loss), 

but the insurance companies only reimbursed approximately $1 million (actual 

loss). 

Abovyan argued that the use of the higher intended loss would cause an 

unwarranted disparity among similarly situated defendants. His codefendant 

Barbuto was held accountable only for the actual loss, as stipulated in her plea 

agreement. The PSI also referenced other co-conspirators’ convictions; they pled 

guilty too, and their sentences were based on actual loss. 

At the sentencing hearing, the district court overruled Abovyan’s objection

and used the intended loss amount. The district court adopted the PSI’s findings 

and guidelines calculations and sentenced Abovyan to 120 months’ imprisonment 

on his Counts One through Eight convictions, to run concurrently, and a 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 43 of 51
44

consecutive 15-month sentence on his Count Nine conviction. 

B. Sentencing Disparity Argument

Abovyan argues that the district court erred in calculating his advisory 

guidelines range based on intended loss, instead of actual loss. Because actual loss 

was the basis for his codefendant and his other co-conspirators’ sentences, 

Abovyan contends the district court created an unwarranted sentencing disparity by 

using the higher intended loss to calculate his guidelines range.

17 

First, there is no guidelines-calculation error. The guidelines define loss as 

the greater of actual or intended loss. See U.S.S.G. § 2B1.1 cmt. n.3(A). The 

district court correctly used the intended loss here because it was greater than the 

actual loss. See id.

Second, the essence of Abovyan’s argument is more that there is an 

unwarranted sentencing disparity, which addresses the reasonableness of the 

sentences. In imposing a sentence, district courts must consider several factors, 

including the need “to avoid unwarranted sentence disparities among defendants 

with similar records who have been found guilty of similar conduct.” 18 U.S.C. 

§ 3553(a)(6). “[D]efendants who cooperate with the government and enter a 

17“This Court reviews de novo the District Court’s interpretation of the guidelines and its 

application of the guidelines to the facts.” United States v. Fox, 926 F.3d 1275, 1278 (11th Cir.), 

cert. denied, __ U.S. __, 140 S. Ct. 639 (2019). We review the reasonableness of a sentence for 

abuse of discretion. Williams, 526 F.3d at 1321. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 44 of 51
45

written plea agreement are not similarly situated to a defendant who provides no 

assistance to the government and proceeds to trial.” United States v. Docampo,

573 F.3d 1091, 1101 (11th Cir. 2009); see also United States v. Jayyousi, 657 F.3d 

1085, 1117–18 (11th Cir. 2011). “There is no unwarranted disparity even when 

the sentence the cooperating defendant receives is substantially shorter.” 

Docampo, 573 F.3d at 1101 (quotation marks omitted).

Because codefendant Barbuto and the other co-conspirators involved in the 

fraud scheme all pled guilty and their plea agreements provided for how loss was 

to be determined, those defendants are not “similarly situated” to Abovyan. See id. 

Therefore, any disparity between the sentences of Abovyan and them is not an 

“unwarranted” sentence disparity within the meaning of § 3553(a)(6), much less 

one that required the district court to impose a lower sentence regardless of the 

other § 3553(a) factors. See 18 U.S.C. § 3553(a) (requiring the district court to 

consider multiple factors, only one of which is the need to avoid unwarranted 

sentence disparities, in choosing the appropriate sentence).18 The district court did 

18To the extent Abovyan argues that the district court’s use of intended loss was 

unconstitutional because it unfairly penalized him for going to trial, his argument is meritless. 

See Frank v. Blackburn, 646 F.2d 873, 882–83 (5th Cir. 1980) (en banc), modified on other 

grounds, 646 F.2d 902 (5th Cir. 1981) (en banc) (explaining that “the mere imposition of a 

longer sentence than defendant would have received had he pleaded guilty” is not automatically 

unconstitutional punishment). Further, Abovyan does not point to any evidence that the district 

court imposed a sentence within the correctly calculated advisory guidelines range to punish him 

for exercising his right to go to trial. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 45 of 51
46

not err in calculating Abovyan’s advisory guidelines range or abuse its discretion 

in sentencing him.

C. Loss Amount and Foreseeability

Abovyan also argues that the district court erred in determining the amount 

of the intended loss because it was not supported by a preponderance of the

evidence. He asserts that the district court failed to make underlying findings as to 

the scope of the criminal activity that Abovyan agreed to undertake and the 

reasonable foreseeability of the loss amount attributed to him.19 

Abovyan waived these arguments because he did not object to the amount of 

the intended loss in the PSI or its foreseeability and, instead, repeatedly told the 

court that he challenged only the use of intended instead of actual loss.20 See

United States v. Bennett, 472 F.3d 825, 832 (11th Cir. 2006) (“[C]hallenges to the 

facts contained in the PSI must be asserted with specificity and clarity. Otherwise, 

the objection is waived.” (citation omitted)); United States v. Wade, 458 F.3d 

1273, 1277 (11th Cir. 2006) (“It is the law of this circuit that a failure to object to 

19“We review a district court’s determination of the loss amount under the Sentencing 

Guidelines for clear error.” Melgen, 967 F.3d at 1265. “Because the district court is in a unique 

position to assess the evidence and estimate the loss based upon that evidence, its loss 

determination is entitled to appropriate deference.” Id. (citing U.S.S.G. § 2B1.1 cmt. n.3(C)).

20Although Abovyan suggested at one point that the loss amount was “not reasonably 

foreseeable” for him, he then clarified that he “agree[d] with the numbers” but objected to using 

the intended loss amount. 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 46 of 51
47

allegations of fact in a PSI admits those facts for sentencing purposes.”). 

In any event, Abovyan’s arguments are meritless. Under the Sentencing 

Guidelines, a defendant’s offense level shall be adjusted based on the reasonably 

foreseeable activity of co-conspirators that is within the scope of and in furtherance 

of the conspiracy. U.S.S.G. § 1B1.3(a)(1)(B). “[T]o determine a defendant’s 

liability for the acts of others, the district court must first make individualized 

findings concerning the scope of criminal activity undertaken by a particular 

defendant.” United States v. Hunter, 323 F.3d 1314, 1319 (11th Cir. 2003) 

(quotation marks omitted). The district court may determine reasonable 

foreseeability only after it makes those individualized findings. Id. However, this 

Court will not vacate a defendant’s sentence based on the district court’s failure to 

make specific findings “[i]f the record otherwise supports the court’s 

determination.” United States v. Baldwin, 774 F.3d 711, 727 (11th Cir. 2014). 

At sentencing, the government presented testimony of an Internal Revenue 

Service special agent, who prepared a “loss amount” chart based on records from 

insurance companies and the Facilities. The billing information contained in the 

chart concerned only the period that Abovyan worked at the Facilities. The chart 

showed that the Facilities billed a total of $1,892,273.15 to seven insurance 

companies for treatment services, but the chart did not include amounts billed to 

the other defrauded insurance companies. The chart showed that Smart Lab billed 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 47 of 51
48

$9,453,468.40 to insurance, but the chart did not include amounts billed by other 

labs, like Ally. Based on those limited numbers alone, the chart calculated that 

insurance companies were billed a total of $11,345,741.55. 

After the special agent’s testimony, the district court found that (1) the loss 

amounts presented by the government relate only to the time when Abovyan was 

there and are actually conservative in terms of total billings, and (2) the 

$11.3 million figure accurately reflects the loss amount. 

The record supports the district court’s findings. As medical director, 

Abovyan authorized the Facilities’ urine testing protocol and signed standing 

consent orders that allowed the Facilities to send urine samples out for lab testing 

at least two to three times per week. He pre-signed Ally requisition forms knowing 

that they would be filled in and copied by Facilities employees. He approved any 

outstanding orders by Dr. Tendler. Abovyan admitted that the Facilities would 

“test for everything,” meaning full panels of tests on each sample, and he reviewed 

and electronically signed the test results. Abovyan knew that the Facilities were 

billing insurance for patient “treatment,” as he admitted that Chatman paid him to 

“use his medical license to bill insurance.” Given Abovyan’s key role in the 

healthcare fraud scheme, the amounts billed to the insurance companies were 

reasonably foreseeable to him. Plus, as the district court noted, the $11.3 million 

figure is conservative because it does not include the amounts billed by toxicology 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 48 of 51
49

labs other than Smart Lab, like Ally, and only includes amounts billed by the 

Facilities to a subset of the 42 defrauded insurance companies. See Melgen, 967 

F.3d at 1265 (“[T]he district court need only reach a reasonable estimate of loss.”). 

Therefore, the district court did not clearly err in reaching its loss findings.

D. Count Two Statutory Penalty

Finally, Abovyan argues that his Count Two sentence exceeds the statutory 

maximum penalty. Count Two alleged that Abovyan conspired to distribute 

controlled substances spanning Schedules II, III, and IV, each of which carries a 

different statutory maximum penalty. Generally, the statutory maximum penalty 

for a Schedule II drug is 20 years, a Schedule III drug is 10 years, and a Schedule 

IV drug is 5 years. 21 U.S.C. § 841(b)(1)(C), (b)(1)(E), (b)(2). The jury rendered 

a general guilty verdict for the Count Two conspiracy offense and did not specify

which substance was involved. 

The government conceded for sentencing purposes that, because the jury did 

not make a specific drug-type finding, Abovyan’s statutory maximum penalty 

should not exceed the penalty for conspiring to dispense the Schedule III 

buprenorphine involved in Counts Three through Nine. On appeal, Abovyan

contends that, due to the ambiguity, he should receive the most lenient statutory 

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 49 of 51
50

maximum penalty of 5 years (Schedule IV).

21 

Because Abovyan did not raise this objection at the sentencing hearing, we 

review for plain error. See United States v. Deason, 965 F.3d 1252, 1265 (11th 

Cir. 2020). In United States v. Candelario, 240 F.3d 1300 (11th Cir. 2001), the 

defendant was convicted of conspiring to traffic, and possessing with intent to 

distribute, crack cocaine. Id. at 1303. During the trial, Candelario’s codefendant 

testified that, as part of the conspiracy, Candelario sold him nine ounces of crack 

cocaine for distribution. Id. at 1303, 1312. The jury, however, did not find the 

drug quantity as to either Candelario’s substantive or conspiracy convictions. See

id. at 1311–12. Despite the district court’s plain error, we declined to vacate the

defendant’s conspiracy sentence because “Count One of the indictment, the 

conspiracy count, necessarily subsumes the amount of cocaine in the possession 

charge.” Id. at 1312. “Because the jury found at least nine ounces of crack 

cocaine in the possession charge, the jury also must have determined that at least 

nine ounces were involved in the conspiracy.” Id. 

The same principle is applied here. It is plain error for a district court to 

“sentence a defendant beyond the maximum sentence for the least serious 

21Abovyan also contends, in a passing statement in his brief, that his total sentence should 

not have exceeded 10 years, but he does not explain why or cite any law in support. 

Accordingly, we deem that issue abandoned. See United States v. Jernigan, 341 F.3d 1273, 1283 

n.8 (11th Cir. 2003).

USCA11 Case: 19-10676 Date Filed: 02/22/2021 Page: 50 of 51
51

substance charged in a multi-object drug conspiracy” “in the absence of a special 

verdict.” United States v. Grow, 977 F.3d 1310, 1330–31 (11th Cir. 2020) 

(quotation marks omitted). But like in Candelario, this error did not affect 

Abovyan’s substantial rights. Because the jury returned convictions for seven 

substantive counts of unlawful distribution of buprenorphine, a Schedule III drug, 

it “also must have determined” that buprenorphine was involved in the conspiracy

to distribute a controlled substance, permitting a statutory penalty of 10 years on 

Count Two. See Candelario, 240 F.3d at 1312; 21 U.S.C. § 841(b)(1)(E); 21 

C.F.R. § 1308.13(e)(2)(i).

VI. CONCLUSION

For the foregoing reasons, we affirm Abovyan’s convictions and sentences.

AFFIRMED.
