Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (40.6%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. Hologic Sales And Service, LLC accounts for 83.3% of it on its own, with 25 other manufacturers making up the rest. Reporting peaked in 2019 at $10,703 and has fallen 85.3% since, to $1,569 in 2025. Among obstetrics & gynecology 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 91 payments — averaging $173.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$15,761 in reported general payments places this provider in the 95th percentile of 1,732 obstetrics & gynecology 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.
