Payments from drug & device makers
What this record shows
The money is spread across several categories — education (43.0%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Arthrex accounts for 65.3% of it on its own, with 10 other manufacturers making up the rest. Reporting peaked in 2020 at $2,347 and has fallen 99.3% since, to $16 in 2024.
Across 61 payments — averaging $98.19 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$5,990 in reported general payments places this provider in the 75th 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Diclofenac Sodium | 50 | $608 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 57 | $549 |
| Celecoxib | 12 | $198 |
| Tramadol Hcl | 45 | $118 |
