Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $6,006,709 of the $6,006,743 with a category attached, or 100.0%. Medtronic accounts for 100.0% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2019 at $1,347,009 and has fallen 64.0% since, to $484,300 in 2025. Among neurological surgery clinicians in AZ 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 118 payments — averaging $50,905 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments

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.
