Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,096 of the $3,479 with a category attached, or 89.0%. It is spread thinly across 10 manufacturers, the largest accounting for just 19.3% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for vascular & interventional radiology clinicians in MO, where the typical reported total is $4,042.
Across 45 payments — averaging $77.30 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 |
|---|---|---|
| Inari Medical, Inc. | 6 | $673 |
| Boston Scientific | 6 | $489 |
| Guerbet LLC | 2 | $458 |
| Balt USA, LLC | 10 | $452 |
| Sirtex Medical Inc | 4 | $359 |
| Medtronic | 4 | $336 |
| Stryker | 5 | $273 |
| Histosonics, Inc. | 1 | $263 |
| Penumbra, Inc. | 6 | $158 |
| Cardiovascular Systems Inc. | 1 | $18 |
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
$3,479 in reported general payments places this provider in the 45th percentile of 81 vascular & interventional radiology providers in Missouri.

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.
