Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $22,000 of the $31,931 with a category attached, or 68.9%. Every reported general payment came from a single manufacturer, Amgen. Among surgery clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 28 payments — averaging $1140.38 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Amgen$32K
Across 7 payments — averaging $305,717 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Amgen$2.1M
What the payments were for
- Consulting fees$22,00069%
- Travel & lodging$9,42830%
- Food & beverage$5022%
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 |
|---|---|---|
| Amgen | 28 | $31,931 |
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
$31,931 in reported general payments places this provider in the 90th percentile of 2,363 surgery providers in California.
