Payments from drug & device makers
What this record shows
The money is spread across several categories — education (52.3%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 78.5% of it on its own, with 10 other manufacturers making up the rest. 2025 is the largest year on record at $4,447, 8.2 times the $543 reported in 2019.
Across 87 payments — averaging $87.93 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 | 16 | $6,003 |
| Asensus Surgical, Inc. | 2 | $490 |
| Coloplast | 51 | $461 |
| Angiodynamics, Inc. | 4 | $344 |
| Astellas Pharma US Inc | 3 | $103 |
| Boston Scientific | 5 | $91 |
| Agiliti Surgical, Inc. | 1 | $85 |
| Myriad Genetic Laboratories, Inc. | 1 | $26 |
| Lumenis, Inc | 2 | $24 |
| Johnson & Johnson | 1 | $17 |
| EDAP Technomed Inc | 1 | $5 |
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
$7,650 in reported general payments places this provider in the 85th percentile of 215 urology providers in Wisconsin.
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 |
|---|---|---|
| Tamsulosin Hcl | 23 | $205 |
| Cephalexin | 20 | $60 |
| Sulfamethoxazole-TrimethoprimSulfamethoxazole/Trimethoprim | 15 | $54 |
