Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $487 of the $542 with a category attached, or 89.7%. It is spread thinly across 17 manufacturers, the largest accounting for just 23.0% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for radiation oncology clinicians in TN, where the typical reported total is $542.
Across 20 payments — averaging $27.12 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Regeneron Healthcare Solutions, Inc.$125
- Exelixis Inc.$56
- Progenics Pharmaceuticals, Inc.$51
- Blue Earth Diagnostics$42
- AVEO Pharmaceuticals, Inc.$40
- E.r. Squibb & Sons, L.L.C.$30
- plus $198 from 11 others
Across 1 payment — averaging $15,900 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Puma Biotechnology, Inc.$16K

- Food & beverage$48790%
- Education$5610%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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.
- LIBTAYO$125
How this compares
$542 in reported general payments places this provider in the 50th percentile of 115 radiation oncology providers in Tennessee.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
