Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 18 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 14 manufacturers, the largest accounting for just 16.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $1,265 and has fallen 90.1% since, to $125 in 2025.

Medicare billing

Part B allowed, 2024

$56,922

Medicare patients

164

Services billed

532

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.
