Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 94.3% of the total across 6 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 6 manufacturers reported payments, led by Histosonics, Inc. at 56.9% of the total. 2025 is the largest year on record at $253, more than ten times the $12 reported in 2021. That places this record below the midpoint for hematology & oncology clinicians in ND, where the typical reported total is $410.
Across 6 payments — averaging $74.07 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

| GE HealthCare | 1 | $73 |

How this compares
$444 in reported general payments places this provider in the 50th percentile of 35 hematology & oncology providers in North 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.
