Payments from drug & device makers
What this record shows
The money is spread across several categories — education (58.1%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 86.1% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2024 at $7,924 and has fallen 97.1% since, to $226 in 2025.
Across 41 payments — averaging $242.63 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

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$2,466
- ACell$907
- QuikClot$144
How this compares
Too few surgical critical care providers in Iowato place this figure against a meaningful peer group, so we don't.
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.
