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.

| Viiv Healthcare Company | 9 | $741 |
| Merck | 5 | $529 |
| Janssen Products, LP | 2 | $241 |

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.
How this compares
$4,675 in reported general payments places this provider in the 80th percentile of 856 infectious disease providers in California.
