Payments from drug & device makers
What this record shows
This record is dominated by grants: $140,083 of the $141,835 with a category attached, or 98.8%. GE HealthCare accounts for 100.0% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2023 at $71,792 and has fallen 99.9% since, to $43 in 2025. Among diagnostic radiology 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 8 payments — averaging $17,729 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$141,835 in reported general payments places this provider in the 95th percentile of 772 diagnostic radiology 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.
