Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $117,425 of the $148,263 with a category attached, or 79.2%. 4 manufacturers reported payments, led by Gilead at 50.7% of the total. Reporting peaked in 2023 at $40,552 and has fallen 63.1% since, to $14,964 in 2025. Among family medicine clinicians in CA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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 | 125 | $75,210 |
| AbbVie | 121 | $72,994 |
| Novo Nordisk | 1 | $32 |
| GSK | 1 | $27 |
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
$148,263 in reported general payments places this provider in the 95th percentile of 10,533 family medicine providers in California.
