Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (44.7%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. 8 manufacturers reported payments, led by Exelixis Inc. at 40.3% of the total. Reporting peaked in 2019 at $3,702 and has fallen 91.3% since, to $322 in 2025. That places this record below the midpoint for hematology & oncology clinicians in TN, where the typical reported total is $5,575.
Across 17 payments — averaging $291.00 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
| Company | Payments | Total |
|---|---|---|
| Exelixis Inc. | 2 | $1,995 |
| Bayer | 3 | $1,669 |
| US Oncology Corporate, Inc. | 3 | $621 |
| Cardinal Health 110 LLC | 1 | $275 |
| Novocure GmbH | 1 | $250 |
| Daiichi Sankyo Inc. | 4 | $88 |
| Tersera Therapeutics LLC | 2 | $38 |
| Gilead | 1 | $12 |
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
$4,947 in reported general payments places this provider in the 45th percentile of 251 hematology & 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.
