Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (37.5%), education and food and beverage — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 92.8% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2022 at $3,719 and has fallen 99.0% since, to $38 in 2025. That places this record below the midpoint for thoracic surgery (cardiothoracic vascular surgery) clinicians in SC, where the typical reported total is $5,278.
Across 24 payments — averaging $237.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

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.
