Payments from drug & device makers
What this record shows

It is spread thinly across 34 manufacturers, the largest accounting for just 16.0% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $639 and has fallen 74.3% since, to $164 in 2025.
Across 154 payments — averaging $18.23 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
