Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 15 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 9 manufacturers, the largest accounting for just 18.1% — the pattern of someone who eats at a lot of different presentations.
Across 15 payments — averaging $28.58 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
Too few vascular & interventional radiology providers in New Hampshireto place this figure against a meaningful peer group, so we don't.
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.
