Payments from drug & device makers
What this record shows
The money is spread across several categories — education (45.1%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 89.5% of it on its own, with 18 other manufacturers making up the rest. 2025 is the largest year on record at $5,439, more than ten times the $310 reported in 2019.
Across 57 payments — averaging $155.67 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
Most prescribed under Part D
