Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $41,743 of the $53,049 with a category attached, or 78.7%. Sirtex Medical Inc accounts for 64.1% of it on its own, with 8 other manufacturers making up the rest. 2025 is the largest year on record at $20,552, more than ten times the $552 reported in 2019. Among vascular & interventional radiology clinicians in MA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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.
