Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $178,074 of the $226,963 with a category attached, or 78.5%. Paragon 28, Inc. accounts for 96.1% of it on its own, with 19 other manufacturers making up the rest. Reporting peaked in 2022 at $56,054 and has fallen 60.2% since, to $22,333 in 2025. Among foot and ankle surgery clinicians in MI with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

How this compares
$226,963 in reported general payments places this provider in the 95th percentile of 384 foot and ankle surgery providers in Michigan.
Medicare billing
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.
