Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 38 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 10 manufacturers reported payments, led by Inari Medical, Inc. at 38.4% of the total. Among emergency medicine clinicians in OK 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

$83,512

Medicare patients

449

Services billed

775

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.
