Payments from drug & device makers

What this record shows

This record is dominated by speaking fees: $90,297 of the $109,202 with a category attached, or 82.7%. 16 manufacturers reported payments, led by Medtronic at 47.2% of the total. Reporting peaked in 2019 at $34,422 and has fallen 62.0% since, to $13,087 in 2025. Among neurological surgery clinicians in IL with any reported payments, this total sits in the top 10% — 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.

Medicare billing

Part B allowed, 2024
$371,491
Medicare patients
417
Services billed
1,227

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.
