Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 91.8% of the total across 66 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 23 manufacturers, the largest accounting for just 15.5% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $776, 3.0 times the $258 reported in 2019.

Medicare billing

Part B allowed, 2024

$150,961

Medicare patients

368

Services billed

2,061

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.
