Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (51.0%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 16 manufacturers reported payments, led by Merck at 24.7% of the total. Reporting peaked in 2019 at $69,139 and has fallen 96.5% since, to $2,435 in 2025. Among anatomic pathology 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 165 payments — averaging $1303.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
