Payments from drug & device makers
What this record shows
The money is spread across several categories — education (49.0%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Arthrex accounts for 65.8% of it on its own, with 12 other manufacturers making up the rest. Reporting peaked in 2021 at $5,774 and has fallen 60.3% since, to $2,294 in 2025.
Across 120 payments — averaging $188.24 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.

How this compares
$22,589 in reported general payments places this provider in the 80th percentile of 381 orthopaedic surgery providers in Tennessee.
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.
