Payments from drug & device makers
What this record shows
This record is dominated by grants: $36,932 of the $37,003 with a category attached, or 99.8%. Genentech, Inc. accounts for 99.8% of it on its own, with 1 other manufacturer making up the rest. Among radiation oncology 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 3 payments — averaging $12,334 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- E.r. Squibb & Sons, L.L.C.$71
Across 1 payment — averaging $146,597 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.

How this compares
$37,003 in reported general payments places this provider in the 95th percentile of 627 radiation oncology 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.
