Payments from drug & device makers
What this record shows
This record is dominated by grants: $12,500 of the $19,897 with a category attached, or 62.8%. Boston Scientific accounts for 73.7% of it on its own, with 11 other manufacturers making up the rest. Reporting peaked in 2023 at $14,149 and has fallen 99.0% since, to $142 in 2025. Among gastroenterology clinicians in FL with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 55 payments — averaging $361.77 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

How this compares
$19,897 in reported general payments places this provider in the 90th percentile of 1,388 gastroenterology providers in Florida.
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.
