What this record shows

Reporting peaked in 2019 at $197 and has fallen 50.6% since, to $97 in 2025.

Across 10 payments — averaging $50.14 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 |
|---|---|---|
| Mevion_medical_systems_inc | 2 | $163 |
| Icotec Medical Inc. | 1 | $107 |
| Novocure Inc. | 1 | $97 |
| Grifols USA, LLC | 2 | $46 |
| Reflexion Medical, Inc. | 1 | $37 |
| Johnson & Johnson | 1 | $17 |
| GT Medical Technologies, Inc | 1 | $17 |
| Medtec LLC | 1 | $17 |
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
$501 in reported general payments places this provider in the 40th percentile of 43 radiation oncology providers in Oklahoma.
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.
