Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (44.5%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. Sanofi-aventis U.S. LLC accounts for 70.1% of it on its own, with 10 other manufacturers making up the rest. 2025 is the largest year on record at $141,878, more than ten times the $5,925 reported in 2019. Among pediatric endocrinology clinicians in TN 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 129 payments — averaging $1969.62 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
