Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 10 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Boston Scientific accounts for 61.1% of it on its own, with 4 other manufacturers making up the rest.
Across 10 payments — averaging $34.86 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- SPR Therapeutics, Inc$47
- Abbott$40

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.
