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.

General payments by program year

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.

How this compares
$109,202 in reported general payments places this provider in the 90th percentile of 302 neurological 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |

| Gabapentin | 48 | $524 |
| Levetiracetam | 14 | $337 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 13 | $117 |
| ClopidogrelClopidogrel Bisulfate | 12 | $104 |
