Payments from drug & device makers
What this record shows
The money is spread across several categories — education (40.1%), royalties or licence payments and speaking fees — rather than concentrated in one kind of arrangement. Skeletal Dynamics Inc accounts for 93.5% of it on its own, with 15 other manufacturers making up the rest. 2025 is the largest year on record at $21,834, more than ten times the $302 reported in 2019.
Across 77 payments — averaging $936.08 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
$72,078 in reported general payments places this provider in the 85th percentile of 110 hand surgery providers in Pennsylvania.
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
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Tramadol Hcl | 53 | $71 |
| Meloxicam | 18 | $47 |
