Payments from drug & device makers

What this record shows

The money is spread across several categories — speaking fees (44.9%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 4 manufacturers reported payments, led by Dentsply IH AB at 40.3% of the total. 2024 is the largest year on record at $22,128, more than ten times the $1,802 reported in 2019. Among physical medicine & rehabilitation 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.

Medicare billing

Part B allowed, 2024

$54,560

Medicare patients

172

Services billed

655

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.
