Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,368 of the $4,007 with a category attached, or 84.1%. 18 manufacturers reported payments, led by Johnson & Johnson at 36.2% of the total. Among physician assistant clinicians in CA 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.
Across 127 payments — averaging $31.55 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
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.

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.
