What this record shows

Reporting peaked in 2019 at $11,979 and has fallen 93.1% since, to $828 in 2023.
Across 673 payments — averaging $33.80 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
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.
How this compares
Too few allergy & immunology providers in Oklahomato place this figure against a meaningful peer group, so we don't.
