Payments from drug & device makers
What this record shows
The money is spread across several categories — other (29.4%), royalties or licence payments and education — rather than concentrated in one kind of arrangement. 10 manufacturers reported payments, led by Maxx Orthopedics, Inc. at 37.2% of the total. Reporting peaked in 2021 at $275,566 and has fallen 91.8% since, to $22,677 in 2025. Among adult reconstructive orthopaedic surgery clinicians in MD with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 204 payments — averaging $3752.54 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
