Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (56.5%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Medical Device Business Services, Inc. accounts for 90.1% of it on its own, with 5 other manufacturers making up the rest. 2025 is the largest year on record at $15,635, more than ten times the $1,450 reported in 2019.
Across 31 payments — averaging $667.67 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

|---|---|---|
| Medical Device Business Services, Inc. | 11 | $18,646 |
| Medtronic(2 entities) | 5 | $923 |
| Microvention, Inc. | 8 | $861 |

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.
- SPOTLIGHT$11,900
- ACTIVA$624
- AXIUM PRIMETM$169
- STENT$149
- ERIC RETRIEVAL DEVICE$149
How this compares
$20,698 in reported general payments places this provider in the 75th 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.
