Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (49.0%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Siemens Medical Solutions USA, Inc. accounts for 72.7% of it on its own, with 10 other manufacturers making up the rest. Reporting peaked in 2023 at $10,971 and has fallen 96.3% since, to $411 in 2025. Among radiation oncology clinicians in MN 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.
Across 35 payments — averaging $391.53 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 |
|---|---|---|
| Siemens Medical Solutions USA, Inc. | 10 | $9,963 |
| Icotec Medical Inc. | 11 | $2,441 |

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
$13,704 in reported general payments places this provider in the 90th percentile of 128 radiation oncology providers in Minnesota.
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 | 21 | $238 |
