Payments from drug & device makers
What this record shows
This record is dominated by grants: $175,704 of the $175,738 with a category attached, or 100.0%. Pfizer accounts for 71.5% of it on its own, with 2 other manufacturers making up the rest. Reporting peaked in 2019 at $77,777 and has fallen 100.0% since, to $34 in 2022. Among dermatology clinicians in PA 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.
Across 9 payments — averaging $19,526 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$175,738 in reported general payments places this provider in the 95th percentile of 626 dermatology 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.
