Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 29 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 17 manufacturers, the largest accounting for just 16.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $214 and has fallen 83.8% since, to $35 in 2024. That places this record below the midpoint for hematology & oncology clinicians in IL, where the typical reported total is $2,365.
Across 29 payments — averaging $17.99 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$522 in reported general payments places this provider in the 30th percentile of 580 hematology & oncology providers in Illinois.
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.
