Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $11,475 of the $11,475 with a category attached, or 100.0%. 3 manufacturers reported payments, led by Roche Products Limited at 54.9% of the total. Reporting peaked in 2021 at $7,200 and has fallen 77.1% since, to $1,650 in 2022. Among internal medicine clinicians in MD with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 5 payments — averaging $2295.00 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 |
|---|---|---|
| Roche Products Limited | 1 | $6,300 |
| Merck | 2 | $2,625 |
| F. Hoffmann-la Roche AG | 2 | $2,550 |
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.
- Xofluza$2,550
- MK-4482$1,500
How this compares
$11,475 in reported general payments places this provider in the 95th percentile of 2,979 internal medicine 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.
