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 |
|---|---|---|
| Seqirus USA Inc | 3 | $6,650 |
| Biocryst Pharmaceuticals, Inc. | 1 | $3,300 |
| Janssen Research & Development, LLC | 1 | $3,200 |

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.
