Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (53.6%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. AbbVie accounts for 74.9% of it on its own, with 30 other manufacturers making up the rest. Reporting peaked in 2019 at $12,014 and has fallen 99.5% since, to $54 in 2024. Among gastroenterology clinicians in AZ 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 613 payments — averaging $40.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
