Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $45,090 of the $63,049 with a category attached, or 71.5%. Zimmer Biomet accounts for 83.5% of it on its own, with 18 other manufacturers making up the rest. Reporting peaked in 2020 at $26,185 and has fallen 98.5% since, to $393 in 2025. Among 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 173 payments — averaging $364.44 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares

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 |

| Diclofenac Sodium | 18 | $265 |
