Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $60,200 of the $97,351 with a category attached, or 61.8%. Skeletal Dynamics Inc accounts for 98.7% of it on its own, with 21 other manufacturers making up the rest. Reporting peaked in 2021 at $51,303 and has fallen 78.6% since, to $10,956 in 2025. Among hand surgery clinicians in AZ with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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
$97,351 in reported general payments places this provider in the 95th percentile of 60 hand surgery providers in Arizona.
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 |
|---|---|---|
| Methylprednisolone | 22 | $121 |
| Sulfamethoxazole-TrimethoprimSulfamethoxazole/Trimethoprim | 28 | $80 |
