What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 3 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Every reported general payment came from a single manufacturer, Salix Pharmaceuticals, A Division Of Bausch Health US, LLC. 2024 is the largest year on record at $125, 7.7 times the $16 reported in 2022. That places this record below the midpoint for gastroenterology clinicians in NY, where the typical reported total is $1,827.

Medicare billing

Part B allowed, 2024

$114,503

Medicare patients

397

Services billed

1,023

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.
