Payments from drug & device makers

What this record shows

This record is dominated by royalties or licence payments: $2,130,378 of the $2,147,936 with a category attached, or 99.2%. Zimmer Biomet accounts for 95.2% of it on its own, with 10 other manufacturers making up the rest. Reporting peaked in 2022 at $677,328 and has fallen 99.3% since, to $4,894 in 2025. Among orthopaedic surgery clinicians in AR 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.

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.

Medicare billing

Part B allowed, 2024
$413,579
Medicare patients
837
Services billed
2,965

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.
