Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (50.1%), education and food and beverage — rather than concentrated in one kind of arrangement. Arthrex accounts for 66.9% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2022 at $3,357 and has fallen 95.6% since, to $147 in 2025.
Across 114 payments — averaging $111.63 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 | 65 | $8,511 |
| Wardlow Enterprises | 17 | $2,234 |
| Zimmer Biomet | 16 | $1,096 |

| Orthofix Medical, Inc. | 1 | $22 |
| Prism Medical | 1 | $19 |
| Ferring Pharmaceuticals Inc. | 1 | $17 |
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.
- Comprehensive Primary Stem$466
- MAKO$297
- Verasense$147
- ROSA$130
How this compares
$12,725 in reported general payments places this provider in the 80th percentile of 233 sports medicine providers in Illinois.
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

| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 146 | $1,619 |
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 29 | $163 |
