Payments from drug & device makers

What this record shows

The money is spread across several categories — education (56.2%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 77.9% of it on its own, with 9 other manufacturers making up the rest. Among obstetrics & gynecology clinicians in PR 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.

Medicare billing

Part B allowed, 2024

$22,094

Medicare patients

Services billed

160

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.
