Ruan-Based § 841 Mens Rea Instruction Error Does Not Vacate § 1347 Healthcare-Fraud Convictions Without Strickland Prejudice

I. Introduction

United States v. Otuonye (10th Cir. Apr. 2, 2026) is a published postconviction decision addressing the downstream effect of a flawed jury instruction on controlled-substance distribution after Ruan v. United States, and whether that instructional error can also undo separate healthcare-fraud convictions.

Defendant Ebube Otuonye, a pharmacist and owner of Neighborhood Pharmacy, was convicted of: (1) controlled-substance conspiracy and distribution (Counts 1–2) based on filling prescriptions allegedly lacking legitimate medical purpose and outside professional practice, and (2) healthcare fraud (Counts 3–4) based on fraudulent Medicare/Medicaid reimbursement claims. After Ruan clarified the mens rea for § 841 prosecutions, Otuonye filed a 28 U.S.C. § 2255 motion alleging ineffective assistance of counsel for failing to object to Instruction 16 governing § 841’s “authorization” exception.

The district court vacated Counts 1–2 (distribution-related) but denied relief on Counts 3–4 (healthcare fraud), concluding the instructional defect did not prejudice those fraud verdicts. The Tenth Circuit affirmed, holding Otuonye failed to show Strickland prejudice as to the fraud counts.

II. Summary of the Opinion

The Tenth Circuit held that even if Instruction 16 misstated the mens rea for unlawful controlled-substance distribution under § 841 (as understood after Ruan), Otuonye did not demonstrate a “reasonable probability” that correcting that instruction would have changed the outcome on the 18 U.S.C. § 1347 healthcare-fraud counts.

Key points:

  • Instruction 16 was expressly limited to Counts 1–2 and did not purport to govern Counts 3–4.
  • Healthcare fraud does not require proof of a § 841 violation; the elements focus on a knowing and willful scheme, material falsity, and specific intent to defraud.
  • The fraud theory centered on noncontrolled prescriptions tied to the pharmacy’s “3:1 Policy,” not reimbursement for controlled substances.
  • Accordingly, there was no Strickland prejudice from trial counsel’s failure to object to Instruction 16 with respect to Counts 3–4.

III. Analysis

A. Precedents Cited

1. Ruan v. United States, 597 U.S. 450 (2022)

Ruan held that to convict under § 841 when a defendant claims “authorization” (e.g., dispensing pursuant to medical practice), the government must prove beyond a reasonable doubt that the defendant knowingly or intentionally acted in an unauthorized manner. Objective unreasonableness may be circumstantial evidence but cannot substitute for proof of scienter.

In Otuonye, Ruan supplies the underlying premise that Instruction 16’s “legitimate medical purpose or usual course” phrasing (and its associated mental-state framing) was problematic for § 841 counts. But the critical question was remedial: whether that error prejudiced separate fraud counts.

2. Strickland v. Washington, 466 U.S. 668 (1984)

Strickland provides the two-part ineffective-assistance framework: deficient performance and prejudice. The Tenth Circuit resolved the appeal on prejudice, emphasizing that a defendant must show a reasonable probability of a different result absent counsel’s error.

3. Yarrington v. Davies, 992 F.2d 1077 (10th Cir. 1993)

Yarrington is cited for the Tenth Circuit’s articulation of the Strickland prejudice standard: whether there is a reasonable probability that, but for counsel’s failure (here, failure to object), the result would have been different. The court also relied on Yarrington for the principle that if prejudice is absent, a court need not address deficiency.

4. United States v. Cook, 49 F.3d 663 (10th Cir. 1995)

Cook is cited for the standard of review: legal conclusions on ineffective-assistance claims are reviewed de novo.

5. United States v. Otuonye, 995 F.3d 1191 (10th Cir. 2021)

The court used its prior direct-appeal opinion as the baseline factual narrative, particularly regarding: (i) DEA concerns about prescribing patterns, (ii) the relationship between Dr. Henson’s prescriptions and Neighborhood Pharmacy, and (iii) evidence supporting the healthcare-fraud theory (especially the “3:1 Policy” and reimbursement practices).

6. The Henson decisions: United States v. Henson (Henson I), 9 F.4th 1258 (10th Cir. 2021); Henson v. United States, 142 S. Ct. 2902 (2022) (mem.); United States v. Henson (Henson II), No. 19-3062, 2023 WL 2319289 (10th Cir. Mar. 2, 2023)

The Supreme Court’s vacatur of Henson I after Ruan and the Tenth Circuit’s action in Henson II illustrate how Ruan required revisiting § 841 convictions where jury instructions failed to capture the necessary scienter. The Otuonye court distinguished that dynamic from healthcare fraud, where § 841 is not an element.

7. United States v. Kahn (Kahn II), 58 F.4th 1308 (10th Cir. 2023) (and related money-laundering authority)

Defendant relied on Kahn II, but the court used it primarily as a contrast. In Kahn II, the Tenth Circuit reversed money-laundering convictions because the laundering offense depended on “specified unlawful activity,” and the jury could have treated the (instructionally flawed) § 841 distributions as the predicate unlawful activity. The opinion’s citation to United States v. Weidner, 437 F.3d 1023 (10th Cir. 2006), reinforces that money laundering can be tethered to predicate offenses like wire fraud.

By contrast, the court emphasized that 18 U.S.C. § 1347 does not require a predicate § 841 conviction (or any other predicate crime); therefore, an instructional flaw in the § 841 instruction does not “automatically” infect the fraud verdicts.

8. Procedural/preservation authorities: United States v. Trent, 884 F.3d 985 (10th Cir. 2018); Nielson v. Ketchum, 640 F.3d 1117 (10th Cir. 2011)

Although not central to the holding, the court addressed the government’s timeliness/preservation arguments by referencing Trent’s “relation back” doctrine: an otherwise late claim may relate back to a timely § 2255 claim if tied to a common core of operative facts. It also cited Nielson for the principle that, absent a cross-appeal, the court would not revisit the government’s loss on Counts 1–2.

9. Out-of-circuit comparisons: United States v. Smithers, 92 F.4th 237 (4th Cir. 2024); United States v. Ignasiak, 667 F.3d 1217 (11th Cir. 2012); United States v. Ruan, 56 F.4th 1291 (11th Cir. 2023)

The court rejected Defendant’s reliance on these decisions:

  • Smithers was distinguished because the “maintaining a place” count was functionally dependent on the mass of § 841 convictions—unlike the independent § 1347 fraud counts here.
  • Ignasiak (a Confrontation Clause case) did not establish a general principle that fraud and distribution counts are always “inextricably intertwined.”
  • The Eleventh Circuit’s post-Ruan decision in United States v. Ruan was used against Defendant: it overturned § 841 convictions but upheld healthcare-fraud convictions, supporting the separability of the offenses depending on how the fraud is charged and proved.

B. Legal Reasoning

The opinion’s reasoning is a structured application of Strickland prejudice to a multi-count verdict. The court’s analysis turned on three interlocking propositions:

1. The jury instruction at issue did not govern the fraud counts

Instruction 16 explicitly stated it was relevant in “two ways”: Counts 1 and 2. The court treated that limiting language as important contextual evidence that the jury was not directed to apply Instruction 16 to Counts 3 and 4. In other words, the alleged instructional defect sat in a compartmented portion of the charge.

2. The healthcare-fraud counts were not “parasitic” on § 841

The court emphasized that Instruction 18 (healthcare fraud) did not include unlawful distribution of controlled substances as an element. Instead, § 1347 required proof of a knowing and willful scheme, material falsehoods, falsity, and specific intent to defraud. This mattered because even a complete unraveling of the distribution theory would not necessarily undermine a separate scheme-to-defraud theory.

3. The fraud proof centered on noncontrolled prescriptions and reimbursement certifications

Factually, the fraud case focused on the pharmacy’s “3:1 Policy”—requiring three noncontrolled prescriptions for each controlled prescription— which the government framed as a means to manipulate wholesaler thresholds and generate reimbursable, medically unnecessary prescriptions. The opinion underscored trial evidence that Medicare and Medicaid reimburse “any prescription for an approved drug” only if for “a legitimate medical purpose,” and that submitting a claim effectively certifies medical necessity.

Critically, evidence suggested Neighborhood Pharmacy seldom billed Medicare/Medicaid for controlled substances (customers often paid cash for controlled prescriptions), while billing occurred predominantly for noncontrolled drugs. That proof route left little causal room for a § 841 mens rea instruction to alter the fraud verdicts.

4. Independent mens rea in § 1347 further broke any linkage

Even accepting Defendant’s premise that Instruction 16 diluted scienter for § 841, the fraud counts required their own mental state findings: knowingly and willfully executing the scheme, and acting with specific intent to defraud, including knowledge (or reckless indifference) to falsity. Thus, the jury could convict on fraud without deciding that Defendant had the subjective criminal intent required for unlawful controlled-substance distribution after Ruan.

5. Outcome: no “reasonable probability” of a different verdict on Counts 3–4

Given the instructions specific to fraud, the prosecution’s theory, and the evidence concerning noncontrolled-drug billing, the court held that Defendant failed to show a reasonable probability that correcting Instruction 16 would have changed the fraud outcome. The court therefore affirmed denial of § 2255 relief for Counts 3–4.

C. Impact

The decision’s practical impact is to limit the collateral reach of Ruan-based instructional challenges in multi-count “pill mill” prosecutions. It establishes (within the Tenth Circuit) that:

  • A flawed § 841 authorization/mens rea instruction does not automatically taint healthcare-fraud convictions under § 1347.
  • To obtain § 2255 relief on non-§ 841 counts, defendants must show case-specific prejudice—e.g., that the fraud theory or the instructions made the fraud verdict depend on the § 841 verdict, or that the jury necessarily relied on the erroneous § 841 instruction to find fraud.
  • The court will scrutinize whether the challenged count is predicate-dependent (as in money laundering in Kahn II) versus independent (as here).

For prosecutors, the opinion implicitly validates charging and trying healthcare fraud on a theory tied to reimbursement certifications and medical necessity—especially where billing is for noncontrolled drugs—without needing to prove (or risk reversal based on) § 841 scienter problems. For defense counsel, it underscores the necessity of building a record that links the fraud theory to the controlled-substance illegality (if such a link exists) and requesting clarifying instructions where theories overlap.

IV. Complex Concepts Simplified

  • 28 U.S.C. § 2255: A federal prisoner’s primary mechanism to collaterally attack a conviction/sentence after the direct appeal is over, often based on constitutional violations (like ineffective assistance of counsel).
  • Ineffective assistance / Strickland test: The defendant must show (1) unreasonable attorney performance and (2) prejudice—a reasonable probability the outcome would have been different.
  • Mens rea / scienter: The required guilty state of mind. Ruan requires proof that the defendant knowingly or intentionally acted without authorization under § 841 when authorization is at issue.
  • “Legitimate medical purpose” and “usual course of professional practice”: Regulatory concepts defining when prescribing/dispensing controlled substances is authorized. After Ruan, the government must also prove the defendant’s subjective knowledge/intent that conduct was unauthorized.
  • Healthcare fraud (§ 1347): Focuses on a knowing, willful scheme to defraud a healthcare benefit program using material falsehoods with intent to deceive/cheat, typically involving improper billing or reimbursement claims.
  • Predicate-dependent counts: Some crimes (e.g., money laundering based on “specified unlawful activity”) can rise or fall with an underlying offense. The court held § 1347 is not inherently predicate-dependent on § 841.
  • “Relation back” (in § 2255 timing): A later-added claim can be treated as timely if it arises from the same core facts as a timely claim.

V. Conclusion

United States v. Otuonye draws a sharp remedial boundary around Ruan-driven instructional error: even if § 841 distribution counts are infected by an incorrect mens rea instruction, separate healthcare-fraud convictions under 18 U.S.C. § 1347 will stand unless the defendant proves Strickland prejudice—a reasonable probability that the fraud verdict would have changed.

The court’s core takeaway is functional and fact-sensitive: when the fraud counts are tried and instructed as independent offenses—especially where the fraudulent billing is for noncontrolled prescriptions—an error in the controlled-substance instruction is unlikely to justify collateral relief on the fraud convictions.
