What this record shows

Reporting peaked in 2022 at $145 and has fallen 85.5% since, to $21 in 2025. That places this record below the midpoint for infectious disease clinicians in MI, where the typical reported total is $216.

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 |
|---|---|---|
| Gilead | 1 | $125 |
| Astellas Pharma US Inc | 1 | $75 |
| Bioventus LLC | 1 | $22 |

How this compares
$263 in reported general payments places this provider in the 50th percentile of 257 infectious disease 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.
