Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $283,412 of the $428,329 with a category attached, or 66.2%. 35 manufacturers reported payments, led by Supernus Pharmaceuticals, Inc. at 28.2% of the total. Reporting peaked in 2019 at $246,187 and has fallen 95.0% since, to $12,300 in 2025. Among neurology 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 448 payments — averaging $956.09 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
How this compares
$428,329 in reported general payments places this provider in the 95th percentile of 941 neurology providers in Pennsylvania.
