Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 35 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 15 manufacturers, the largest accounting for just 20.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $203 and has fallen 92.7% since, to $15 in 2025. That places this record below the midpoint for surgery clinicians in SD, where the typical reported total is $829.
Across 35 payments — averaging $17.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$619 in reported general payments places this provider in the 45th percentile of 87 surgery providers in South Dakota.
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 |
|---|---|---|
| Pantoprazole Sodium | 42 | $624 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 12 | $69 |
