Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (48.6%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. Nevro Corp. accounts for 67.2% of it on its own, with 21 other manufacturers making up the rest. Reporting peaked in 2019 at $262,435 and has fallen 94.8% since, to $13,554 in 2025. Among pain medicine 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 814 payments — averaging $962.26 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
