What this record shows

Arthrex accounts for 87.8% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2022 at $16,710 and has fallen 99.9% since, to $23 in 2024.
Across 26 payments — averaging $645.36 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$16,779 in reported general payments places this provider in the 75th 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.
Most prescribed under Part D

| Meloxicam | 579 | $1,295 |
