Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $8,187 of the $11,139 with a category attached, or 73.5%. Novo Nordisk AS accounts for 74.8% of it on its own, with 11 other manufacturers making up the rest. Reporting peaked in 2019 at $9,480 and has fallen 94.9% since, to $482 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.

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 |
|---|---|---|
| Novo NordiskRybelsus, Ozempic | $2,264 | $158,496116 claims |
| AstraZenecaFarxiga | $75 | $37,26530 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 10,533 family medicine providers in California.
