Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $74,458 of the $96,840 with a category attached, or 76.9%. Saluda Medical Americas, Inc. accounts for 69.9% of it on its own, with 26 other manufacturers making up the rest. Reporting peaked in 2024 at $51,291 and has fallen 77.8% since, to $11,375 in 2025. Among pain medicine 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.

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
$96,840 in reported general payments places this provider in the 95th percentile of 182 pain medicine 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.
