Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 96.7% of the total across 178 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 20 manufacturers reported payments, led by AbbVie at 30.5% of the total. Reporting peaked in 2023 at $3,415 and has fallen 65.0% since, to $1,195 in 2025. Among physician assistant 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 178 payments — averaging $41.18 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
