Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 14 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 9 manufacturers reported payments, led by Siemens Medical Solutions USA, Inc. at 28.8% of the total. 2025 is the largest year on record at $178, 5.7 times the $31 reported in 2019. That places this record below the midpoint for radiation oncology clinicians in CA, where the typical reported total is $477.

How this compares
$371 in reported general payments places this provider in the 45th 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.
