Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $1,187,312 of the $1,586,595 with a category attached, or 74.8%. Zimmer Biomet accounts for 98.8% of it on its own, with 11 other manufacturers making up the rest. 2025 is the largest year on record at $428,685, 4.7 times the $91,745 reported in 2019. Among orthopedic surgery clinicians in MD with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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.
