Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (57.5%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 15 manufacturers reported payments, led by Novartis at 52.7% of the total. Reporting peaked in 2019 at $129,091 and has fallen 99.8% since, to $226 in 2025. Among neurology clinicians in CA 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 348 payments — averaging $734.86 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
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.
