Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 52 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 13 manufacturers reported payments, led by Novartis at 26.2% of the total. Reporting peaked in 2019 at $237 and has fallen 52.7% since, to $112 in 2025.

How this compares
$879 in reported general payments places this provider in the 70th percentile of 4,567 internal medicine 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.
