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.
| Company | Payments | Total |
|---|---|---|
| Acadia Pharmaceuticals Inc | 219 | $166,413 |
| Harmony Biosciences LLC | 4 | $10,470 |
| Shionogi Inc | 4 | $6,717 |
| Sanofi | 3 | $62 |
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.
