Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $7,448 of the $12,001 with a category attached, or 62.1%. Roche Diagnostics International Ltd accounts for 71.9% of it on its own, with 9 other manufacturers making up the rest. Reporting peaked in 2024 at $9,011 and has fallen 81.8% since, to $1,644 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.
