Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $6,759 of the $8,573 with a category attached, or 78.8%. 12 manufacturers reported payments, led by Butterfly Network, Inc. at 46.2% of the total. Reporting peaked in 2024 at $4,440 and has fallen 82.9% since, to $758 in 2025. Among emergency medicine 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 23 payments — averaging $372.74 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$8,573 in reported general payments places this provider in the 95th percentile of 6,006 emergency medicine 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.
