Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (46.5%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 33 manufacturers reported payments, led by Nuwellis, Inc. at 50.0% of the total. Reporting peaked in 2023 at $254,821 and has fallen 78.3% since, to $55,385 in 2025. Among advanced heart failure and transplant cardiology 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.
