Payments from drug & device makers
What this record shows

It is spread thinly across 21 manufacturers, the largest accounting for just 20.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $607 and has fallen 56.9% since, to $261 in 2025.
Across 75 payments — averaging $20.30 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
