Payments from drug & device makers

What this record shows

This record is dominated by food and beverage: $1,567 of the $1,959 with a category attached, or 80.0%. It is spread thinly across 17 manufacturers, the largest accounting for just 23.1% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for dermatology clinicians in TN, where the typical reported total is $3,452.

Medicare billing

Part B allowed, 2024

$188,820

Medicare patients

569

Services billed

3,183

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.
