Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $58,840 of the $74,076 with a category attached, or 79.4%. Gilead accounts for 92.8% of it on its own, with 20 other manufacturers making up the rest. Reporting peaked in 2019 at $25,638 and has fallen 98.8% since, to $317 in 2025. Among gastroenterology clinicians in FL 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.

How this compares
$74,076 in reported general payments places this provider in the 95th 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.
