Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (58.3%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 17 manufacturers reported payments, led by Argenx US, Inc. at 33.0% of the total. Among neurology clinicians in WA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 362 payments — averaging $877.29 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Argenx US, Inc.$105K
- UCB, Inc.$86K
- AstraZeneca$82K
- Alnylam Pharmaceuticals Inc.$38K
- Johnson & Johnson$4K
- Merck Kgaa$2K
- plus $1K from 11 others
Across 15 payments — averaging $19,781 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 |
|---|---|---|
| Argenx US, Inc. | 133 | $104,787 |
| UCB, Inc. | 81 | $85,587 |

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
$317,578 in reported general payments places this provider in the 95th percentile of 418 neurology providers in Washington.
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.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| Argenx US, Inc.Vyvgart Hytrulo | $104,787 | $429,91526 claims |
| UCB, Inc.Rystiggo | $85,587 | $288,40319 claims |
| CSL BehringPrivigen | $58 | $210,48017 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 418 neurology providers in Washington.
