Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.9% of the total across 396 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. AbbVie accounts for 99.5% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2023 at $1,765 and has fallen 66.5% since, to $592 in 2025. Among anesthesiology 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.
Across 396 payments — averaging $20.09 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| AbbVie(2 entities) | 394 | $7,918 |
| Galderma Laboratories, L.p. | 2 | $36 |
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.
- BOTOX COSMETIC$245
How this compares
$7,955 in reported general payments places this provider in the 95th percentile of 5,717 anesthesiology providers in California.
