What this record shows

Abbott accounts for 62.6% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2022 at $874 and has fallen 58.4% since, to $364 in 2025. That places this record below the midpoint for thoracic surgery (cardiothoracic vascular surgery) clinicians in MN, where the typical reported total is $2,388.

Who reported the general payments

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
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.
