Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (59.0%), travel and lodging and education — rather than concentrated in one kind of arrangement. Pfizer accounts for 71.6% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2019 at $1,915 and has fallen 83.4% since, to $319 in 2024.
Across 20 payments — averaging $128.09 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments

What the payments were tied to
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.
