Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 286 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 37 manufacturers reported payments, led by Sanofi at 29.1% of the total. Among dermatopathology clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 286 payments — averaging $22.40 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$6,407 in reported general payments places this provider in the 90th percentile of 76 dermatopathology 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.
