Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (57.1%), consulting fees and education — rather than concentrated in one kind of arrangement. 18 manufacturers reported payments, led by 3M Company at 41.6% of the total. Reporting peaked in 2019 at $560 and has fallen 63.7% since, to $203 in 2025.
Across 39 payments — averaging $30.82 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Regeneron Healthcare Solutions, Inc.$114
- Incyte Corporation$83

- plus $299 from 12 others
What the payments were for
- Consulting fees$50042%
- Food & beverage$68757%
- Education$151%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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 |
|---|---|---|
| 3M Company | 1 | $500 |
| Regeneron Healthcare Solutions, Inc. | 7 | $114 |
| Incyte Corporation | 4 | $83 |
| Johnson & Johnson | 4 | $71 |
| AbbVie | 1 | $70 |
| Sanofi | 4 | $65 |
| Lilly USA, LLC | 4 | $60 |
| Amgen | 3 | $52 |
| Janssen Scientific Affairs, LLC | 1 | $45 |
| Novartis | 2 | $24 |

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
$1,202 in reported general payments places this provider in the 80th percentile of 273 dermatology providers in Minnesota.
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.
