Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 1 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Every reported general payment came from a single manufacturer, Shionogi Inc.
Across 1 payment — averaging $114.16 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Shionogi Inc$114
Across 19 payments — averaging $8686.78 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.
- Pfizer$165K
What the payments were for
- Food & beverage$114100%
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.
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 |
|---|---|---|
| Shionogi Inc | 1 | $114 |
How this compares
$114 in reported general payments places this provider in the 55th percentile of 186 infectious disease 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.
Most prescribed under Part D
