Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (44.2%), consulting fees and education — rather than concentrated in one kind of arrangement. Vilex LLC accounts for 74.9% of it on its own, with 35 other manufacturers making up the rest. Reporting peaked in 2021 at $18,377 and has fallen 83.1% since, to $3,110 in 2025. Among foot & ankle surgery clinicians in CA 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.
Across 126 payments — averaging $496.02 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$62,498 in reported general payments places this provider in the 95th percentile of 1,126 foot & ankle surgery providers in California.
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 |

| Ketoconazole | 17 | $329 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 41 | $296 |

| Cephalexin | 30 | $134 |
| Mupirocin | 28 | $130 |
