Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $6,000 of the $7,487 with a category attached, or 80.1%. Siemens Medical Solutions USA, Inc. accounts for 85.0% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2024 at $6,625 and has fallen 98.0% since, to $133 in 2025. Among radiation oncology clinicians in VA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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 |
|---|---|---|
| Siemens Medical Solutions USA, Inc. | 2 | $6,363 |
| Varian Medical Systems, Inc. | 1 | $290 |
| Bioprotect Medical, Inc. | 3 | $262 |
| Theragenics Corporation | 1 | $257 |
| Pfizer | 1 | $133 |
| Isoray, Inc | 1 | $106 |
| Elekta, Inc. | 1 | $76 |
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
$7,487 in reported general payments places this provider in the 90th percentile of 121 radiation oncology providers in Virginia.
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 |
|---|---|---|
| Tamsulosin Hcl | 72 | $775 |
Paid to pharmacies, not to this prescriber.
