Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $396,910 of the $398,792 with a category attached, or 99.5%. Pfizer accounts for 99.5% of it on its own, with 36 other manufacturers making up the rest. Reporting peaked in 2020 at $194,367 and has fallen 99.9% since, to $160 in 2025. Among rheumatology clinicians in NJ 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.
