Payments from drug & device makers

What this record shows

The money is spread across several categories — consulting fees (52.7%), food and beverage and speaking fees — rather than concentrated in one kind of arrangement. Shockwave Medical, Inc accounts for 65.5% of it on its own, with 15 other manufacturers making up the rest. 2025 is the largest year on record at $39,379, more than ten times the $164 reported in 2019. Among vascular surgery 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.

Medicare billing

Part B allowed, 2024

$388,174

Medicare patients

906

Services billed

2,700

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.
