Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,320 of the $4,025 with a category attached, or 82.5%. It is spread thinly across 41 manufacturers, the largest accounting for just 21.5% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $3,891, more than ten times the $35 reported in 2019. That places this record below the midpoint for hematology & oncology clinicians in DC, where the typical reported total is $4,025.
Across 141 payments — averaging $28.55 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were for

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.

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
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| KisqaliRibociclib Succinate | 26 | $373,153 |
| Letrozole | 110 | $2,745 |
| Anastrozole | 63 | $1,371 |
| Tamoxifen Citrate | 18 | $314 |
| Ondansetron OdtOndansetron | 13 | $230 |
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 |
|---|---|---|
| NovartisKisqali | $865 | $373,15326 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 69 hematology & oncology providers in District of Columbia.
