Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (47.0%), education and travel and lodging — rather than concentrated in one kind of arrangement. Synthes GmbH accounts for 70.4% of it on its own, with 5 other manufacturers making up the rest. 2025 is the largest year on record at $4,030, more than ten times the $21 reported in 2019.
Across 13 payments — averaging $409.57 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Zimmer Biomet$218
- Elite Orthopedics, LLC$90
- Linvatec Corporation$49

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 |
|---|---|---|
| Synthes GmbH | 5 | $3,747 |
| Medwest Associates | 1 | $1,200 |
| Zimmer Biomet | 3 | $218 |
| Elite Orthopedics, LLC | 2 | $90 |
| Linvatec Corporation | 1 | $49 |
| Stryker | 1 | $20 |
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
$5,324 in reported general payments places this provider in the 70th percentile of 127 sports medicine providers in Missouri.
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.
