Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $53,820 of the $53,885 with a category attached, or 99.9%. Merck accounts for 74.7% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2022 at $13,485 and has fallen 70.0% since, to $4,040 in 2025. Among gynecologic oncology 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.

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.
