Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 17 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Indivior Inc. accounts for 95.3% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2024 at $210 and has fallen 76.1% since, to $50 in 2025.
Across 17 payments — averaging $16.05 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Indivior Inc.$260

Across 5 payments — averaging $187,726 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
