Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (38.0%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. Ipsen Innovation accounts for 61.4% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2023 at $515 and has fallen 66.2% since, to $174 in 2025. That places this record below the midpoint for neurological surgery clinicians in CA, where the typical reported total is $3,356.
Across 7 payments — averaging $119.88 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Ipsen Innovation$515

- Jazz Pharmaceuticals Inc.$150

Across 1,017 payments — averaging $3798.15 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

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 |
|---|---|---|
| Ipsen Innovation | 4 | $515 |
| Avadel CNS Pharmaceuticals, LLC | 1 | $150 |
| Jazz Pharmaceuticals Inc. | 1 | $150 |
| Johnson & Johnson | 1 | $24 |
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
$839 in reported general payments places this provider in the 30th percentile of 773 neurological surgery providers in California.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
