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.

| Adaptive Biotechnologies Corporation | 1 | $143 |
| Syndax Pharmaceuticals, Inc. | 1 | $127 |
| Seagen Inc. | 2 | $99 |
| Jazz Pharmaceuticals Inc. | 2 | $91 |
| THD America, Inc. | 1 | $90 |
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.
