Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $1,056,609 of the $1,056,609 with a category attached, or 100.0%. Merck accounts for 61.8% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2021 at $358,456 and has fallen 88.1% since, to $42,540 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 433 payments — averaging $2440.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
