Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $331,761 of the $427,051 with a category attached, or 77.7%. 39 manufacturers reported payments, led by Otsuka America Pharmaceutical, Inc. at 59.5% of the total. Reporting peaked in 2023 at $107,365 and has fallen 82.0% since, to $19,317 in 2025. Among nephrology clinicians in KY 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.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
How this compares
$427,051 in reported general payments places this provider in the 95th percentile of 165 nephrology providers in Kentucky.
