Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $217,200 of the $242,283 with a category attached, or 89.6%. Every reported general payment came from a single manufacturer, AbbVie. Reporting peaked in 2023 at $113,804 and has fallen 52.6% since, to $53,950 in 2025. Among registered nurse 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 419 payments — averaging $578.24 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.
| Company | Payments | Total |
|---|---|---|
| AbbVie(2 entities) | 419 | $242,283 |
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.
How this compares
$242,283 in reported general payments places this provider in the 95th percentile of 533 registered nurse providers in California.
