Payments from drug & device makers
What this record shows
This record is dominated by other: $1,179,909 of the $1,184,135 with a category attached, or 99.6%. Medtronic accounts for 99.6% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2023 at $1,181,909 and has fallen 99.8% since, to $2,024 in 2025. Among diagnostic radiology clinicians in MN 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.

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.
