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 |
|---|---|---|
| Sanofi-aventis U.S. LLC | 1 | $1,184 |
| National Marrow Donor Program | 6 | $1,106 |
| AstraZeneca | 1 | $150 |
| Jazz Pharmaceuticals Inc. | 1 | $121 |
| Vertex | 1 | $63 |
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.
