Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $104 of the $133 with a category attached, or 78.5%. 3 manufacturers reported payments, led by Sanofi at 56.0% of the total.
Across 4 payments — averaging $33.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Sanofi$74
- Bristol Myers Squibb$30
- Merck$28
Across 86 payments — averaging $3396.92 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.

- AbbVie$72K
- Janssen Research & Development, LLC$41K
What the payments were for
- Food & beverage$10479%
- Education$2821%
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.
| Company | Payments | Total |
|---|---|---|
| Sanofi | 1 | $74 |
| Bristol Myers Squibb | 1 | $30 |
| Merck | 2 | $28 |
How this compares
Too few hematology providers in Kentuckyto place this figure against a meaningful peer group, so we don't.
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.
Most prescribed under Part D

| Lenalidomide | 153 | $2,219,889 |

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 |
|---|---|---|
| Bristol Myers SquibbRevlimid, Thalomid | $30 | $1,647,793110 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. There are too few hematology providers in Kentuckyon file to place this against a meaningful peer group, so we don't.
