Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $62,113 of the $91,212 with a category attached, or 68.1%. 6 manufacturers reported payments, led by Merck at 48.9% of the total. Among infectious disease 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.

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.

| Merck | 25 | $44,565 |
| Gilead | 26 | $22,765 |

| Viiv Healthcare Company | 1 | $2,760 |
| Janssen Scientific Affairs, LLC | 1 | $800 |
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
$91,212 in reported general payments places this provider in the 95th percentile of 156 infectious disease providers in Tennessee.
