Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (53.8%), travel and lodging and grants — rather than concentrated in one kind of arrangement. 35 manufacturers reported payments, led by Medtronic at 26.7% of the total. 2025 is the largest year on record at $8,579, more than ten times the $665 reported in 2019.
Across 400 payments — averaging $95.38 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- W. L. Gore & Associates, Inc.$4K
- Shape Memory Medical Inc.$3K
- Silk Road Medical, Inc.$3K
- Cook Medical LLC$2K

Across 45 payments — averaging $2669.23 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

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.

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
Too few vascular surgery providers in South Dakotato 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| EliquisApixaban | 16 | $12,912 |
| ClopidogrelClopidogrel Bisulfate | 81 | $1,143 |
| Atorvastatin Calcium | 83 | $904 |
| Amlodipine Besylate | 12 | $66 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 14 | $60 |
