Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.2% of the total across 253 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 43 manufacturers, the largest accounting for just 12.9% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $2,286, more than ten times the $25 reported in 2020. That places this record below the midpoint for hematology & oncology clinicians in TN, where the typical reported total is $5,575.
Across 253 payments — averaging $22.56 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.
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
$5,708 in reported general payments places this provider in the 50th percentile of 251 hematology & oncology providers in Tennessee.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| EliquisApixaban | 20 | $16,107 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 13 | $101 |
| Prednisone | 12 | $62 |
Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| PfizerEliquis | $213 | $16,10720 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 50th percentile of 251 hematology & oncology providers in Tennessee.
