Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $1,274 of the $1,829 with a category attached, or 69.7%. Arthrex accounts for 83.0% of it on its own, with 2 other manufacturers making up the rest. 2024 is the largest year on record at $1,413, more than ten times the $135 reported in 2019. That places this record below the midpoint for orthopaedic surgery clinicians in NY, where the typical reported total is $4,024.
Across 23 payments — averaging $79.52 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.
| Company | Payments | Total |
|---|---|---|
| Arthrex | 20 | $1,518 |
| Gotham Surgical Solutions & Devices, Inc. | 2 | $176 |
| Stryker | 1 | $135 |
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
$1,829 in reported general payments places this provider in the 35th percentile of 1,079 orthopaedic surgery providers in New York.
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.
