Payments from drug & device makers

What this record shows

The money is spread across several categories — consulting fees (59.5%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Edwards Lifesciences accounts for 95.5% of it on its own, with 13 other manufacturers making up the rest. 2025 is the largest year on record at $38,925, 2.6 times the $15,139 reported in 2019. Among thoracic surgery (cardiothoracic 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

$241,462

Medicare patients

149

Services billed

433

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.
