Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (41.5%), consulting fees and education — rather than concentrated in one kind of arrangement. 15 manufacturers reported payments, led by Davol Inc. at 43.6% of the total. Reporting peaked in 2022 at $59,352 and has fallen 93.2% since, to $4,045 in 2025. Among surgery clinicians in NC 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.
Across 143 payments — averaging $926.29 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year

What the payments were tied to
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
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.
