Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 35 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Getinge USA Sales, LLC accounts for 61.7% of it on its own, with 6 other manufacturers making up the rest. 2025 is the largest year on record at $225, 2.1 times the $109 reported in 2021.
Across 35 payments — averaging $24.93 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$872 in reported general payments places this provider in the 70th percentile of 335 surgical 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.
