Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $5,704 of the $6,904 with a category attached, or 82.6%. Johnson & Johnson accounts for 71.2% of it on its own, with 5 other manufacturers making up the rest. That places this record below the midpoint for neurological surgery clinicians in NV, where the typical reported total is $6,847.
Across 279 payments — averaging $24.74 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 |
|---|---|---|
| Johnson & Johnson(2 entities) | 251 | $4,914 |
| Globus Medical | 21 | $1,838 |
| Relievant Medsystems, Inc. | 2 | $57 |
| Stryker | 2 | $45 |
| Medtronic(2 entities) | 2 | $36 |
| Lifenet Health | 1 | $14 |
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
$6,904 in reported general payments places this provider in the 50th percentile of 45 neurological surgery providers in Nevada.
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.
