Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $13,636 of the $21,124 with a category attached, or 64.6%. Intuitive Surgical accounts for 89.1% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2019 at $11,852 and has fallen 93.4% since, to $782 in 2025. Among 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.
Across 68 payments — averaging $310.65 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.
| Company | Payments | Total |
|---|---|---|
| Intuitive Surgical | 51 | $18,822 |
| Vector Surgical, LLC | 7 | $1,182 |
| Endomagnetics Ltd | 6 | $753 |
| Elucent Medical | 2 | $242 |
| Leica Microsystems Inc. | 1 | $104 |
| Hologic Sales And Service, LLC | 1 | $21 |
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.
- Da Vinci Surgical System$17,977
- Magseed$555
- MarginMarker$350
- Magtrace$153
- Mammotome elite$104
How this compares
$21,124 in reported general payments places this provider in the 90th percentile of 1,180 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.
