Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $385,867 of the $424,475 with a category attached, or 90.9%. Organon accounts for 63.8% of it on its own, with 2 other manufacturers making up the rest. Reporting peaked in 2019 at $110,333 and has fallen 71.6% since, to $31,352 in 2025. Among obstetrics & gynecology 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 661 payments — averaging $642.17 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 |
|---|---|---|
| Organon | 437 | $271,009 |
| Merck | 223 | $153,436 |
| AstraZeneca | 1 | $30 |
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.
