Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (51.8%), food and beverage and education — rather than concentrated in one kind of arrangement. Arthrex accounts for 78.2% of it on its own, with 2 other manufacturers making up the rest. Among sports medicine clinicians in MI 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 203 payments — averaging $98.08 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 |
|---|---|---|
| Arthrex | 139 | $15,577 |
| Pinnacle, Inc | 63 | $4,295 |
| Bioventus LLC | 1 | $38 |
How this compares
$19,910 in reported general payments places this provider in the 90th percentile of 145 sports medicine 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.
