Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (54.6%), food and beverage and education — rather than concentrated in one kind of arrangement. Medtronic accounts for 72.5% of it on its own, with 27 other manufacturers making up the rest. Reporting peaked in 2023 at $1,719 and has fallen 70.7% since, to $503 in 2025. That places this record below the midpoint for neurological surgery clinicians in AZ, where the typical reported total is $3,798.
Across 85 payments — averaging $49.69 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$4,223 in reported general payments places this provider in the 50th percentile of 173 neurological surgery providers in Arizona.
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 |
|---|---|---|
| Carbamazepine | 13 | $862 |
| Oxcarbazepine | 11 | $279 |
| Levetiracetam | 12 | $239 |
| Alprazolam | 13 | $9 |
