What this record shows
This record is dominated by food and beverage: $2,355 of the $3,647 with a category attached, or 64.6%. 10 manufacturers reported payments, led by Monteris Medical Corporation at 29.7% of the total. Reporting peaked in 2023 at $1,062 and has fallen 57.5% since, to $451 in 2025. That places this record below the midpoint for neurological surgery clinicians in CA, where the typical reported total is $3,356.

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 |
|---|---|---|
| Monteris Medical Corporation | 8 | $1,082 |
| Globus Medical | 7 | $724 |
| Brainlab, Inc. | 2 | $550 |
| Novocure Inc. | 5 | $410 |
| GT Medical Technologies, Inc | 2 | $219 |
| Telix Pharmaceuticals | 2 | $202 |
| Integra Lifesciences Corporation | 6 | $167 |
| Servier Pharmaceuticals LLC | 1 | $139 |
| Actelion Pharmaceuticals US, Inc. | 1 | $122 |
| Zimmer Biomet | 2 | $33 |
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
$3,647 in reported general payments places this provider in the 50th 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Levetiracetam | 14 | $150 |
Paid to pharmacies, not to this prescriber.
