Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $4,525 of the $5,393 with a category attached, or 83.9%.

Reporting peaked in 2019 at $2,447 and has fallen 98.5% since, to $36 in 2024.
Across 228 payments — averaging $23.66 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
