Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $7,835 of the $8,716 with a category attached, or 89.9%. It is spread thinly across 34 manufacturers, the largest accounting for just 19.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2024 at $2,196 and has fallen 50.2% since, to $1,094 in 2025.
Across 275 payments — averaging $31.69 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

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
$8,716 in reported general payments places this provider in the 75th percentile of 104 vascular surgery providers in Maryland.
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

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 |
|---|---|---|
| Johnson & JohnsonXarelto | $366 | $125,485144 claims |
| PfizerEliquis | $384 | $85,124107 claims |
| Smith+NephewSantyl | $265 | $11,50115 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 75th percentile of 104 vascular surgery providers in Maryland.
