Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,681 of the $3,397 with a category attached, or 78.9%. It is spread thinly across 18 manufacturers, the largest accounting for just 23.7% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for hand surgery clinicians in TN, where the typical reported total is $3,914.
Across 33 payments — averaging $102.94 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

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
$3,397 in reported general payments places this provider in the 45th percentile of 60 hand 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.
