Payments from drug & device makers
What this record shows
This record is dominated by education: $383,000 of the $428,067 with a category attached, or 89.5%. Intuitive Surgical accounts for 99.9% of it on its own, with 2 other manufacturers making up the rest. Among obstetrics 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 225 payments — averaging $1902.52 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 |
|---|---|---|
| Intuitive Surgical | 219 | $427,496 |
| Gilead | 3 | $321 |
| Merck | 3 | $249 |
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.
- Da Vinci Surgical System$427,459
- Vemlidy$200
