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 |
|---|---|---|
| Alnylam Pharmaceuticals Inc. | 3 | $12,430 |
| Novo Nordisk | 8 | $8,690 |
| Travere Therapeutics, Inc. | 5 | $3,419 |
| Novo Nordisk Health Care AG | 3 | $2,745 |
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.
- OXLUMO$8,110
- (815) Thiola$3,200
- Rivfloza$105
How this compares
