Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (37.4%), education and speaking fees — rather than concentrated in one kind of arrangement. Arthrex accounts for 76.0% of it on its own, with 12 other manufacturers making up the rest. Reporting peaked in 2022 at $14,622 and has fallen 99.2% since, to $110 in 2025.
Across 81 payments — averaging $395.80 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 | 51 | $24,377 |
| Impactortho, Inc. | 6 | $4,440 |
| Sportstek Medical, Inc | 4 | $2,280 |
| Stryker | 3 | $433 |
| Elevate Surgical Co | 3 | $132 |
| Johnson & Johnson(2 entities) | 7 | $121 |

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
$32,060 in reported general payments places this provider in the 85th percentile of 662 sports medicine providers in California.
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 |
|---|---|---|
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 59 | $632 |
| Cephalexin | 40 | $356 |
Paid to pharmacies, not to this prescriber.
