Payments from drug & device makers

What this record shows

The money is spread across several categories — food and beverage (32.5%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 25 manufacturers reported payments, led by Boston Scientific at 38.8% of the total. Reporting peaked in 2023 at $14,263 and has fallen 69.8% since, to $4,303 in 2025. Among vascular surgery clinicians in ME with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

Medicare billing

Part B allowed, 2024

$62,081

Medicare patients

188

Services billed

409

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.
