Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $89,668 of the $145,607 with a category attached, or 61.6%. 44 manufacturers reported payments, led by Neurocrine Biosciences, Inc. at 51.0% of the total. Among neurology clinicians in AZ with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
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.
