Payments from drug & device makers

What this record shows

The money is spread across several categories — grants (40.3%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. 21 manufacturers reported payments, led by Medtronic at 32.4% of the total. Among clinical cardiac electrophysiology clinicians in IA 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

Part B allowed, 2024

$109,708

Medicare patients

611

Services billed

1,512

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.
