Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 34 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 12 manufacturers reported payments, led by Merz North America, Inc. at 28.7% of the total. Reporting peaked in 2019 at $566 and has fallen 75.0% since, to $142 in 2025. That places this record below the midpoint for plastic and reconstructive surgery clinicians in MI, where the typical reported total is $1,935.

Medicare billing

Part B allowed, 2024

$96,554

Medicare patients

247

Services billed

835

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.
