Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,339 of the $2,681 with a category attached, or 87.3%. It is spread thinly across 9 manufacturers, the largest accounting for just 22.1% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $986 and has fallen 87.7% since, to $121 in 2025. That places this record below the midpoint for vascular & interventional radiology clinicians in MI, where the typical reported total is $2,535.
Across 26 payments — averaging $103.12 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

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.
