Payments from drug & device makers
What this record shows
This record is dominated by other: $589,102 of the $602,245 with a category attached, or 97.8%. Linvatec Corporation accounts for 98.4% of it on its own, with 16 other manufacturers making up the rest. Reporting peaked in 2022 at $521,742 and has fallen 99.9% since, to $344 in 2025. Among foot & ankle surgery clinicians in TX 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
$602,245 in reported general payments places this provider in the 95th percentile of 684 foot & ankle surgery providers in Texas.
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 |
|---|---|---|
| Celecoxib | 38 | $464 |
| Mupirocin | 43 | $364 |
| Acetaminophen-CodeineAcetaminophen With Codeine | 24 | $180 |
| Methylprednisolone | 15 | $95 |
| Amoxicillin | 13 | $42 |
| Tramadol Hcl | 14 | $41 |
