Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (58.6%), travel and lodging and consulting fees — rather than concentrated in one kind of arrangement. 12 manufacturers reported payments, led by Merck at 56.8% of the total. Reporting peaked in 2019 at $168,929 and has fallen 70.7% since, to $49,422 in 2025. Among endocrinology, diabetes & metabolism clinicians in TN 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 257 payments — averaging $1583.97 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
