Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (53.5%), food and beverage and education — rather than concentrated in one kind of arrangement. Arthrex accounts for 97.0% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2023 at $1,468 and has fallen 61.6% since, to $564 in 2025.
Across 38 payments — averaging $76.32 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.

| Bioventus LLC | 1 | $29 |

How this compares
$2,900 in reported general payments places this provider in the 55th 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.
