What this record shows
This record is dominated by food and beverage: $1,920 of the $2,378 with a category attached, or 80.7%. It is spread thinly across 44 manufacturers, the largest accounting for just 13.7% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,060 and has fallen 74.1% since, to $274 in 2022.
Across 139 payments — averaging $17.11 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
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.
- THERASPHERE$108
