Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (59.6%), food and beverage and education — rather than concentrated in one kind of arrangement. AstraZeneca accounts for 68.6% of it on its own, with 38 other manufacturers making up the rest. Reporting peaked in 2020 at $5,895 and has fallen 82.7% since, to $1,019 in 2025. Among radiation oncology clinicians in PA 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.
Across 165 payments — averaging $59.02 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$9,738 in reported general payments places this provider in the 90th percentile of 339 radiation oncology providers in Pennsylvania.
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.
