Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $4,845 of the $7,589 with a category attached, or 63.8%. It is spread thinly across 23 manufacturers, the largest accounting for just 16.4%. Reporting peaked in 2019 at $2,286 and has fallen 75.2% since, to $568 in 2025. Among prosthodontics clinicians in NY with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 136 payments — averaging $55.80 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
