Payments from drug & device makers
What this record shows
The money is spread across several categories — education (52.1%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. Arthrex accounts for 67.3% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2020 at $2,575 and has fallen 97.6% since, to $63 in 2025. That places this record below the midpoint for orthopaedic surgery clinicians in VA, where the typical reported total is $3,465.
Across 53 payments — averaging $69.66 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
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

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
$3,692 in reported general payments places this provider in the 50th percentile of 473 orthopaedic surgery providers in Virginia.
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.
