Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $99,468 of the $140,260 with a category attached, or 70.9%. Biogen accounts for 66.2% of it on its own, with 24 other manufacturers making up the rest. Among neurology clinicians in MT 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.
Across 383 payments — averaging $366.21 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
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.
