Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $491 of the $564 with a category attached, or 87.1%. 9 manufacturers reported payments, led by Sanofi at 27.6% of the total. 2025 is the largest year on record at $296, 4.1 times the $73 reported in 2020. That places this record below the midpoint for dermatology clinicians in SD, where the typical reported total is $1,250.
Across 21 payments — averaging $26.85 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 |
|---|---|---|
| Sanofi | 7 | $156 |
| Lilly USA, LLC | 1 | $125 |
| Regeneron Healthcare Solutions, Inc. | 3 | $103 |
| AbbVie | 4 | $68 |
| Sun Pharmaceutical Industries Inc. | 2 | $38 |
| Johnson & Johnson | 1 | $32 |
| UCB, Inc. | 1 | $17 |
| Incyte Corporation | 1 | $14 |
| Pfizer | 1 | $12 |
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.
- EBGLYSS$125
How this compares
$564 in reported general payments places this provider in the 30th percentile of 44 dermatology 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.
