Payments from drug & device makers
What this record shows
This record is dominated by other: $12,826,686 of the $12,845,708 with a category attached, or 99.9%. AbbVie accounts for 99.9% of it on its own, with 6 other manufacturers making up the rest. 2025 is the largest year on record at $12,833,456, more than ten times the $6,632 reported in 2019. Among allergy & immunology 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.
