Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $103,708 of the $136,087 with a category attached, or 76.2%. AbbVie accounts for 95.4% of it on its own, with 13 other manufacturers making up the rest. Reporting peaked in 2019 at $47,111 and has fallen 88.9% since, to $5,240 in 2025. Among pediatric gastroenterology clinicians in AZ 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.
