Payments from drug & device makers
What this record shows
This record is dominated by ownership interests: $35,681 of the $40,991 with a category attached, or 87.0%. Hologic Inc accounts for 99.1% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2020 at $35,700 and has fallen 99.5% since, to $177 in 2024. Among diagnostic radiology clinicians in CA 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 16 payments — averaging $2561.94 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$40,991 in reported general payments places this provider in the 95th percentile of 3,537 diagnostic radiology providers in California.
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.
