Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.0% of the total across 498 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 27 manufacturers reported payments, led by Medtronic at 33.8% of the total. 2025 is the largest year on record at $5,131, more than ten times the $216 reported in 2021. Among physician assistant clinicians in NY 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 498 payments — averaging $24.90 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
