Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (45.1%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. 23 manufacturers reported payments, led by Celularity Inc. at 47.5% of the total. Reporting peaked in 2019 at $6,635 and has fallen 69.2% since, to $2,045 in 2025. Among foot surgery clinicians in IL 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 93 payments — averaging $143.65 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to

How this compares
$13,359 in reported general payments places this provider in the 95th percentile of 51 foot surgery providers in Illinois.
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.
