Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (32.7%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. AstraZeneca accounts for 66.6% of it on its own, with 16 other manufacturers making up the rest. Reporting peaked in 2024 at $36,094 and has fallen 79.4% since, to $7,434 in 2025. 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
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.
