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.

|---|---|---|
| Jazz Pharmaceuticals Inc. | 5 | $9,890 |
| Servier Affaires Medicales | 5 | $9,876 |
| Servier Pharmaceuticals LLC | 7 | $5,184 |
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.
