Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $266,467 of the $339,744 with a category attached, or 78.4%. It is spread thinly across 28 manufacturers, the largest accounting for just 22.9%. Reporting peaked in 2019 at $165,589 and has fallen 100.0% since, to $20 in 2023. Among gastroenterology 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.
