Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 93.6% of the total across 18 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 6 manufacturers reported payments, led by AstraZeneca at 34.8% of the total. That places this record below the midpoint for neurology clinicians in AZ, where the typical reported total is $1,232.
Across 18 payments — averaging $17.41 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- AstraZeneca$109
- Argenx US, Inc.$84
- Eisai Inc.$64
- Grifols USA, LLC$21
- Travere Therapeutics, Inc.$20
- EMD Serono, Inc.$16
Across 27 payments — averaging $1863.72 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 |
|---|---|---|
| AstraZeneca | 1 | $109 |
| Argenx US, Inc. | 1 | $84 |
| Eisai Inc. | 3 | $64 |
| Grifols USA, LLC | 1 | $21 |
| Travere Therapeutics, Inc. | 11 | $20 |
| EMD Serono, Inc. | 1 | $16 |
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.
- SOLIRIS$109
How this compares
$313 in reported general payments places this provider in the 30th percentile of 388 neurology 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.
