AdvanceMed Audit Notice as Proof of Willfulness and Post-Charge Misconduct as Grounds for Upward Variance in Medicare Hospice Fraud

Case: United States v. Akula (5th Cir. June 8, 2026)
Court: United States Court of Appeals for the Fifth Circuit
Topic: Medicare hospice fraud (18 U.S.C. § 1347), expert qualification/harmless error, sufficiency of evidence (Rule 29), upward variances and Eighth Amendment proportionality

I. Introduction

United States v. Akula arises from hospice provider Canon Healthcare, LLC (“Canon”), owned and operated by Dr. Shiva Akula in New Orleans. The Government alleged Canon executed a long-running Medicare fraud scheme by (1) routinely billing hospice patients at the higher-paying General Inpatient Care (“GIP”) per diem level without adequate clinical documentation, and (2) separately billing Medicare using CPT codes for services that hospice per diem rates already covered (including CPT 99236, 99233, and 99350).

After a jury convicted Dr. Akula of 23 counts of health care fraud under 18 U.S.C. § 1347, he appealed on three grounds: (1) the district court’s refusal to qualify his witness as an expert in Medicare billing/coding, (2) insufficiency of evidence of “knowing and willful” fraud, and (3) the constitutionality and substantive reasonableness of a 240-month above-Guidelines sentence. The Fifth Circuit affirmed across the board.

II. Summary of the Opinion

A. Expert testimony

The Fifth Circuit held that—even assuming arguendo error in excluding Dr. Gregg Davis as a Medicare billing/coding expert—any error was harmless because there was no “reasonable probability” the exclusion contributed to conviction, given (i) overwhelming evidence of guilt, (ii) Dr. Akula’s own trial theory conceding billing errors while shifting blame, and (iii) Dr. Davis still testified as a clinical expert on hospice eligibility.

B. Sufficiency of the evidence

Viewing the evidence in the light most favorable to the verdict, the court held a rational jury could find Dr. Akula knowingly and willfully executed a scheme to defraud Medicare. The court emphasized circumstantial evidence of intent, including Dr. Akula’s receipt of a 2015 AdvanceMed audit letter reporting 100% denial of reviewed claims and overpayment, his failure to inform staff or change practices, and testimony showing his control over billing personnel (including family members) and efforts to discourage inquiry.

C. Sentencing

The court rejected Dr. Akula’s unpreserved Eighth Amendment claim under plain-error review because the 20-year sentence was not “grossly disproportionate” to a multi-year scheme involving $84 million in billed Medicare claims and approximately $42 million paid.

The court also affirmed the substantive reasonableness of the 52-month upward variance (240 months total), concluding the district court permissibly relied on 18 U.S.C. § 3553(a) factors, including seriousness of the offense, deterrence, protection of the public, and promotion of respect for the law. It further held the district court could consider Dr. Akula’s lack of remorse, repeated bond/court-order violations, and other conduct demonstrating disrespect for the legal system.

III. Analysis

A. Precedents Cited

1. Expert testimony, gatekeeping, and harmless error

  • Moore v. Ashland Chem. Inc. and General Elec. Co. v. Joiner: Cited for the abuse-of-discretion standard governing admission/exclusion of expert testimony. They anchor appellate deference to trial-court gatekeeping decisions about expertise and fit.
  • United States v. De Leon: Supplies the criminal harmless-error standard for excluded evidence—convictions are not reversed unless there is a “reasonable probability” the exclusion contributed to conviction. This standard did the decisive work: even if the district court was wrong about Dr. Davis’s billing expertise, the Fifth Circuit found the evidentiary record too strong to show prejudice.
  • United States v. Kuhrt: Reinforces that exclusion of defense evidence is not reversible when the Government presents ample proof of active fraud and the excluded testimony is not “indispensable.”

2. Sufficiency review and proving fraudulent intent

  • United States v. Kieffer: Confirms that a Rule 29 motion preserves a sufficiency challenge for de novo review.
  • United States v. Scott, Terry v. Hooper, and Jackson v. Virginia: Provide the controlling sufficiency framework—highly deferential to the verdict, asking only whether any rational trier of fact could find the elements beyond a reasonable doubt when viewing evidence favorably to the prosecution.
  • United States v. Umawa Oke Imo: Sets out the statutory elements of 18 U.S.C. § 1347 and ties them to Medicare as a “health care benefit program,” framing the mens rea question (“knowingly and willfully”) central to Dr. Akula’s appeal.
  • United States v. Willett: Establishes that intent to defraud may be inferred from circumstantial evidence and that shared or overlapping supervisory authority does not negate an inference of an owner/operator’s culpable intent.
  • United States v. Sanjar: Supports the proposition that fraudulent intent is typically proven through surrounding circumstances rather than direct “smoking gun” evidence. The Fifth Circuit used this to validate intent inferences drawn from audit notice, continued conduct, and operational control.
  • United States v. Gibson: Authorizes juries to disbelieve a defendant who blames “rogue subordinates” and instead credit other testimony showing managerial involvement.

3. Sentencing review, proportionality, and variances

  • United States v. Ayelotan: Governs plain-error review for unpreserved Eighth Amendment sentencing challenges.
  • United States v. Thomas, United States v. Harris, and McGruder v. Puckett: Define the Fifth Circuit’s Eighth Amendment proportionality method: a threshold comparison of offense gravity and sentence severity, proceeding to comparative analysis only if “gross disproportionality” appears. The court found no threshold showing here.
  • Gall v. United States: Provides the abuse-of-discretion framework for substantive reasonableness and underscores appellate deference to a district court’s explanation and § 3553(a) balancing, even for significant variances.
  • United States v. Smith: Articulates a structured way to identify substantively unreasonable sentences: over/undervaluing relevant factors, relying on improper factors, or making a clear error of judgment in balancing.
  • United States v. Hudgens: Recognizes that being within the statutory maximum supports substantive reasonableness and collects cases upholding “major” upward variances.
  • United States v. Douglas: Confirms “lack of remorse” is an appropriate sentencing consideration, supporting the district court’s reliance on Dr. Akula’s non-acceptance of responsibility (as framed through § 3553(a)’s “promote respect for the law” and related purposes).

B. Legal Reasoning

1. Expert exclusion: the appeal turns on harmlessness

The opinion’s expert-testimony section is less about redefining who qualifies as a billing/coding expert and more about appellate consequence. Even though the district court emphasized Dr. Davis’s lack of specialized billing credentials (no coder certification, no prior expert qualification, no scholarship/teaching in the field, and an expert report focused on clinical care rather than billing compliance), the Fifth Circuit elected to resolve the claim on harmless-error grounds.

The court’s key logic: Dr. Akula claimed Canon’s billing mistakes existed but were attributable to others, while Dr. Davis (as proffered on billing) would have supported the contradictory view that Canon billed properly. Given that internal inconsistency and the weight of the Government’s proof, the panel found no reasonable probability the excluded billing opinion would have changed the verdict.

2. Sufficiency: audit notice + continued conduct + operational control supports “knowing and willful” fraud

Dr. Akula did not contest that Canon billed incorrectly and was paid improperly; he contested intent. The Fifth Circuit treated intent as a classic circumstantial-evidence question for the jury under Jackson v. Virginia.

The court highlighted a fact pattern with strong probative force on willfulness: receipt of a detailed AdvanceMed audit letter stating 100% denial of reviewed claims, documentation failures, coding problems, and overpayment; followed by concealment (not informing staff) and inaction (no corrective change), with similar issues recurring in later audits. In the panel’s view, a rational juror could infer that continued higher-reimbursement billing in the face of explicit notice was not mere negligence but a knowing decision to persist.

Operational evidence reinforced the inference: testimony that Dr. Akula managed daily operations, supervised the family members handling billing, and discouraged probing questions. His signed Medicare enrollment documents further supported the inference that he understood compliance duties and could not plausibly disclaim all responsibility.

3. Sentencing: proportionality is a high bar; § 3553(a) permits emphasis on respect-for-law considerations

On the Eighth Amendment claim, the court applied the Fifth Circuit’s threshold “gross disproportionality” test and found none: the fraud amounts were immense, the conduct spanned years, and the 20-year sentence was far below the aggregate statutory maximum (10 years per count).

On substantive reasonableness, the court emphasized that the district judge tied the upward variance to multiple § 3553(a) purposes—seriousness, deterrence (including general deterrence for the regional health-care market), protection of the public, and promoting respect for the law. The judge specifically cited Dr. Akula’s lack of responsibility acceptance, repeated bond violations, and other conduct as indicative of disrespect for law— considerations the Fifth Circuit treated as legitimate under its precedent (including United States v. Douglas) rather than impermissible punishment for going to trial.

C. Impact

  • Medicare fraud intent proof: The decision underscores that explicit payer/auditor notice (here, AdvanceMed’s audit letter) followed by continued noncompliant billing can be powerful circumstantial evidence of “knowing and willful” intent under 18 U.S.C. § 1347—particularly when an owner-operator controls billing personnel and processes.
  • Defense expert strategy: Even where the defense disputes the Government’s billing expert, appellate reversal is unlikely absent a concrete showing that the excluded testimony could have plausibly altered the verdict. Where the defendant’s own testimony concedes billing errors, attempting to present an expert who says billing was proper may backfire (as it did here) by highlighting internal inconsistency and diminishing prejudice.
  • Upward variances in white-collar cases: The opinion signals continued Fifth Circuit comfort with significant upward variances in major fraud cases when the sentencing judge gives a detailed § 3553(a) explanation tied to deterrence and respect for law, including reliance on bond violations and post-charge behavior reflecting contempt for legal process.
  • Eighth Amendment challenges remain rare: By reaffirming the “gross disproportionality” threshold and emphasizing statutory maxima, the decision reinforces the steep hurdle defendants face in attacking lengthy fraud sentences as cruel and unusual.

IV. Complex Concepts Simplified

  • Hospice “per diem” levels (Routine, Respite, GIP, Continuous Care): Medicare often pays hospice providers a daily rate that varies by the intensity/setting of care. “GIP” is intended for acute symptoms requiring inpatient-level management and pays more than routine/respite care. Overuse of GIP without documentation can indicate upcoding.
  • CPT codes: Standardized billing codes for physician services. In this case, Canon billed separate CPT codes (e.g., 99236, 99233, 99350) for services the Government contended were already included in the hospice per diem—raising “double billing” concerns.
  • 18 U.S.C. § 1347 (“knowingly and willfully”): Health care fraud requires more than mistakes. The Government must prove the defendant knew about the fraudulent nature of the scheme and intended to defraud. Direct proof is rare; juries often infer intent from patterns, notice, concealment, and control.
  • Rule 29 motion (judgment of acquittal): A request that the judge set aside the jury’s verdict because the evidence was insufficient as a matter of law. On appeal, courts apply a highly deferential standard to the verdict.
  • Harmless error (evidence exclusion): Even if a trial judge makes a mistake excluding evidence, the conviction stands unless the defendant shows a reasonable probability the mistake affected the outcome.
  • Upward variance: A sentence above the advisory Guidelines range based on the judge’s consideration of § 3553(a) factors (e.g., deterrence, seriousness, respect for law). It is not automatically suspect; the key is a reasoned explanation.
  • Eighth Amendment proportionality: For non-capital sentences, courts first ask whether a sentence is “grossly disproportionate” to the offense. If not, the inquiry typically ends.

V. Conclusion

United States v. Akula affirms convictions and a substantial upward variance in a large-scale Medicare hospice fraud case and, in doing so, highlights three practical rules. First, appellate courts will often resolve expert-exclusion disputes through harmless-error analysis when the record contains overwhelming evidence of guilt. Second, “knowing and willful” fraud under 18 U.S.C. § 1347 may be inferred where an owner receives clear audit notice of improper billing yet continues the same practices while controlling billing operations. Third, in major health care fraud cases, a detailed § 3553(a) explanation can sustain a significant upward variance, including reliance on lack of remorse and defendant conduct showing disrespect for the rule of law—while Eighth Amendment disproportionality remains an exceptionally difficult challenge.
