Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (58.1%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. It is spread thinly across 17 manufacturers, the largest accounting for just 20.6%. Reporting peaked in 2019 at $29,629 and has fallen 99.9% since, to $24 in 2024. Among neurology with special qualifications in child neurology 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.
Across 87 payments — averaging $969.17 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
