Payments from drug & device makers

What this record shows

This record is dominated by food and beverage: $3,742 of the $4,665 with a category attached, or 80.2%. It is spread thinly across 28 manufacturers, the largest accounting for just 22.0% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for vascular surgery clinicians in MO, where the typical reported total is $6,319.

What the payments were tied to

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.

How this compares

$4,665 in reported general payments places this provider in the 40th percentile of 92 vascular surgery providers in Missouri.

Medicare billing

Part B allowed, 2024
$69,826
Medicare patients
315
Services billed
548

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.
