Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,222 of the $1,391 with a category attached, or 87.9%. It is spread thinly across 9 manufacturers, the largest accounting for just 17.7% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2024 at $714 and has fallen 63.2% since, to $263 in 2025. Among internal medicine clinicians in WA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 15 payments — averaging $92.74 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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 |
|---|---|---|
| E.r. Squibb & Sons, L.L.C. | 2 | $246 |
| AstraZeneca | 4 | $203 |
| Inari Medical, Inc. | 2 | $188 |
| Astellas Pharma US Inc | 2 | $169 |
| Stryker | 1 | $164 |
| Boston Scientific | 1 | $141 |
| Takeda Pharmaceuticals U.S.A., Inc. | 1 | $125 |
| Sobi, Inc | 1 | $88 |
| Ceribell, Inc. | 1 | $68 |
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.
- FlowTriever$164
- EKOSONIC$141
- FLOWTRIEVER CATHETER, S$128
- CT THROMBECTOMY SYSTEM KIT$128
- FRUZAQLA$125

How this compares
$1,391 in reported general payments places this provider in the 90th percentile of 2,038 internal medicine 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.
