Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $10,800 of the $12,251 with a category attached, or 88.2%. Teleflex LLC accounts for 96.3% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2022 at $8,834 and has fallen 99.4% since, to $49 in 2025. Among anesthesiology 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 30 payments — averaging $408.35 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments

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.

How this compares
$12,251 in reported general payments places this provider in the 95th percentile of 1,149 anesthesiology providers in North Carolina.
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.
