Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $2,813 of the $3,926 with a category attached, or 71.6%. AbbVie accounts for 73.2% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2023 at $2,872 and has fallen 91.8% since, to $237 in 2025. Among anatomic pathology & clinical pathology clinicians in IL with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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.
