Background

Dr. John Stevenson Bynon, Jr. was the Director of Abdominal Organ Transplantation and Surgical Director of Liver Transplantation at Memorial Hermann Health System’s Texas Medical Center in Houston, where he served as the primary transplant surgeon in the national Organ Procurement and Transplant Network. A federal grand jury indicted him on five counts of making materially false statements in connection with a health care benefit program, in violation of 18 U.S.C. § 1035. The government alleged that Dr. Bynon entered fabricated donor-matching criteria into UNOS’s UNet platform for five patients—specifying donor age and weight parameters that could only be satisfied by small, obese children—despite those patients being adults. According to the indictment, the manipulated criteria rendered the patients functionally ineligible to receive organ offers through UNOS’s matching system during the relevant periods.

The UNOS system, which has operated the national organ-matching registry since 1984 under contract with the federal Organ Procurement and Transplant Network, relies on accurate patient medical data—including immunological factors and donor-matching parameters such as donor size and weight—to connect transplant candidates with compatible donors. The government’s theory was that by entering unrealistic criteria, Dr. Bynon made false statements about his patients’ medical needs, effectively sidelining them from the matching queue.

Dr. Bynon filed three pretrial motions: (1) a motion to dismiss the indictment for failure to state an offense; (2) a motion to strike certain allegations as surplusage; and (3) a motion to suppress evidence from a search of his cell phone. The government conceded it would not use any evidence obtained directly or indirectly from the cell-phone search, and the parties agreed at oral argument on June 1, 2026 that the suppression motion was moot.

The Court’s Holding

Senior U.S. District Judge Lee H. Rosenthal denied the motion to dismiss, denied the motion to strike (while entering a corresponding limine order), and denied the suppression motion as moot. On the central dismissal question, the court held that whether Dr. Bynon’s donor-acceptance-criteria adjustments constituted statements “capable of being true or false” under 18 U.S.C. § 1035 is a fact-dependent inquiry that cannot be resolved before trial on the current record. The court distinguished the Supreme Court’s ruling in Williams v. United States, 458 U.S. 279 (1982)—which held that depositing a bad check is not a “false statement” because a check has independent legal significance and makes no factual representation—observing that every case applying Williams was decided after a full evidentiary record, not on a pretrial motion to dismiss.

The court found that the meaning of a donor-acceptance-criteria adjustment is contextual and could, depending on UNOS policies and practices, constitute an implied factual assertion about a patient’s medical condition. The court pointed to UNOS COVID-19 guidance—which instructed physicians to set donor age criteria at “98 years (minimum) and 99 years (maximum)” to signal that a patient should not receive organ offers due to COVID-19—as illustrating how such adjustments can communicate factual propositions within an established regulatory framework. The court also rejected Dr. Bynon’s fallback argument that donor-acceptance adjustments at most express medical judgment immune from false-statement liability, holding that even sincerely held opinions imply the fact that the speaker holds the stated belief, which may be proven false if the speaker knew the belief was unfounded.

On the statutory elements, the court further held that the indictment adequately alleged a “matter involving a health care benefit program” because both Medicare (which paid the alleged victims’ expenses) and the UNOS matching network (which operates under a federal contract to provide organ-matching services) qualify under § 24(b)’s broad definition. The court denied the motion to strike, concluding that the challenged allegations were sufficiently relevant to the charged offenses to survive under the strict surplusage standard, but issued a limine order addressing how that content may be presented to a jury.

Key Takeaways

  • Entering false donor-matching criteria in the UNOS UNet system may constitute a “false statement” under 18 U.S.C. § 1035 if the surrounding regulatory framework—including UNOS policies and published guidance—gives the criteria objective communicative meaning; the issue is fact-intensive and not resolvable pretrial on an incomplete record.
  • The Williams v. United States “no factual assertion” defense does not automatically bar prosecution for manipulating a computerized matching system; courts applying Williams have done so post-verdict, and the defense requires a fully developed factual record about what the system’s inputs communicate within their regulatory context.
  • A physician’s medical judgment is not categorically exempt from § 1035 liability; even an opinion implies the fact that the speaker genuinely holds it, and evidence that a doctor subjectively disbelieved his own stated clinical criteria can support a false-statement conviction.
  • Both Medicare and UNOS’s organ-matching network qualify as “health care benefit programs” under the broad definition in 18 U.S.C. § 24(b), satisfying that statutory element of § 1035.
  • The government’s concession not to use any evidence—direct or derivative—from a warrantless cell-phone search rendered the suppression motion moot, avoiding a constitutional ruling on the search’s validity.

Why It Matters

This case tests the outer boundary of federal healthcare false-statement law in a novel context: the manipulation of a life-or-death algorithmic matching system rather than a billing record or reimbursement claim. The court’s refusal to dismiss signals that physicians who adjust organ-recipient criteria in ways inconsistent with their patients’ actual medical needs—and contrary to the regulatory expectations embedded in UNOS policies—face meaningful criminal exposure under § 1035, even absent a direct billing fraud. The decision may prompt transplant centers and their counsel to scrutinize internal practices around donor-acceptance criteria and the documentation supporting any non-standard adjustments.

The opinion also adds to a growing body of district court authority working out the boundaries of Williams v. United States in digital and algorithmic settings, where “statements” may take the form of database entries, system parameters, or software inputs rather than traditional written or oral representations. How courts ultimately define “false statement” in these contexts will have broad implications for fraud prosecutions in telemedicine, electronic health records, and other data-driven healthcare systems.
