What this record shows

Reporting peaked in 2023 at $479 and has fallen 71.9% since, to $135 in 2024. That places this record below the midpoint for hematology clinicians in MN, where the typical reported total is $422.
Across 13 payments — averaging $80.19 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 |
|---|---|---|
| Exelixis Inc. | 2 | $273 |
| AstraZeneca | 2 | $212 |
| Janssen Scientific Affairs, LLC | 2 | $190 |
| Takeda Pharmaceuticals U.S.A., Inc. | 2 | $120 |
| ADC Therapeutics America, Inc. | 1 | $99 |
| Astellas Pharma US Inc | 1 | $81 |
| 180 Medical, Inc. | 1 | $27 |
| Genentech USA, Inc. | 1 | $22 |
| Amgen | 1 | $17 |
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
$1,042 in reported general payments places this provider in the 50th percentile of 111 hematology 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Anastrozole | 19 | $410 |
| Prochlorperazine Maleate | 14 | $262 |
| Omeprazole | 13 | $99 |
Paid to pharmacies, not to this prescriber.
