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.

|---|---|---|
| Biomarin Pharmaceutical Inc. | 1 | $2,833 |
| Cleerly, Inc. | 1 | $56 |
| Amgen | 1 | $15 |
| Travere Therapeutics, Inc. | 1 | $1 |
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.
