Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (44.2%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. 31 manufacturers reported payments, led by Salix Pharmaceuticals, A Division Of Bausch Health US, LLC at 52.3% of the total. Reporting peaked in 2024 at $15,376 and has fallen 56.6% since, to $6,666 in 2025. Among gastroenterology clinicians in NM 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.
