Thoracic Surgery (Cardiothoracic Vascular Surgery) · Charleston, SCNPI 1891715215

Payments from drug & device makers

What this record shows

The money is spread across several categories — consulting fees (48.4%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 24 manufacturers reported payments, led by Edwards Lifesciences at 44.5% of the total. Reporting peaked in 2024 at $116,356 and has fallen 54.9% since, to $52,444 in 2025. Among thoracic surgery (cardiothoracic vascular surgery) clinicians in SC 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.

What the payments were tied to

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.

Medicare billing

Part B allowed, 2024
$258,369
Medicare patients
269
Services billed
450

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.
