Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $411,145 of the $411,145 with a category attached, or 100.0%. Merck accounts for 98.5% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2020 at $179,645 and has fallen 97.1% since, to $5,200 in 2025. Among diagnostic radiology 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 263 payments — averaging $1563.29 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

|---|---|---|
| Merck | 261 | $404,970 |
| Janssen Research & Development, LLC | 2 | $6,175 |
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.

$411,145 in reported general payments places this provider in the 95th percentile of 1,665 diagnostic radiology providers in Pennsylvania.
