Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (51.5%), food and beverage and consulting fees — rather than concentrated in one kind of arrangement. 33 manufacturers reported payments, led by AbbVie at 46.3% of the total. 2025 is the largest year on record at $27,650, more than ten times the $2,438 reported in 2021. Among physician assistant clinicians in CO 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 1,055 payments — averaging $64.58 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
