Payments from drug & device makers

What this record shows

The money is spread across several categories — speaking fees (29.3%), food and beverage and other — rather than concentrated in one kind of arrangement. 17 manufacturers reported payments, led by Sirtex Medical Inc at 25.9% of the total. Among vascular & interventional radiology clinicians in AR 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

$2,590,670

Medicare patients

2,379

Services billed

100,770

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.

Most prescribed under Part D

Drug	Claims	Cost to plans & patients
Methylprednisolone	21	$152
Pantoprazole Sodium	18	$121
Ciprofloxacin Hcl	21	$53

Paid to pharmacies, not to this prescriber.
