Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $143,184 of the $200,745 with a category attached, or 71.3%. Boston Scientific accounts for 82.6% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2019 at $139,149 and has fallen 99.9% since, to $119 in 2025. Among interventional cardiology clinicians in WI 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.
