Payments from drug & device makers
What this record shows
This record is dominated by grants: $36,932 of the $42,390 with a category attached, or 87.1%. Genentech, Inc. accounts for 87.1% of it on its own, with 2 other manufacturers making up the rest. Among radiation oncology clinicians in MI 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.

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 |
|---|---|---|
| Genentech, Inc. | 2 | $36,932 |
| Agios Pharmaceuticals, Inc. | 6 | $5,443 |
| Boston Scientific | 1 | $15 |
How this compares
$42,390 in reported general payments places this provider in the 95th percentile of 198 radiation oncology providers in Michigan.
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.
