Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (51.2%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. AbbVie accounts for 66.1% of it on its own, with 16 other manufacturers making up the rest. Reporting peaked in 2019 at $4,928 and has fallen 99.5% since, to $24 in 2025.
Across 139 payments — averaging $45.09 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.
