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 |
|---|---|---|
| Gilead | 116 | $3,093 |
| Viiv Healthcare Company | 66 | $1,480 |
| Johnson & Johnson(2 entities) | 33 | $536 |
| Merck | 22 | $490 |
| EMD Serono, Inc. | 15 | $294 |
| Napo Pharmaceuticals Inc | 15 | $246 |
| Janssen Products, LP | 2 | $111 |
| Argenx US, Inc. | 1 | $32 |
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.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| GileadBiktarvy, Descovy | $3,093 | $1,078,304279 claims |
| Viiv Healthcare CompanyTriumeq, Dovato, Tivicay, Juluca | $1,480 | $424,098129 claims |
| Janssen Products, LPSymtuza | $111 | $73,18315 claims |
| Napo Pharmaceuticals IncMytesi | $246 | $31,24911 claims |
| MerckJanuvia | $490 | $8,84017 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 10,634 family providers in California.
