Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $228,500 of the $281,679 with a category attached, or 81.1%. Duchesnay USA Incorporated accounts for 99.6% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2019 at $230,704 and has fallen 99.8% since, to $428 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.
