Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $1,339,300 of the $1,339,348 with a category attached, or 100.0%. Merck accounts for 81.4% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2021 at $702,009 and has fallen 91.4% since, to $60,095 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.
