Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $116,400 of the $192,465 with a category attached, or 60.5%. Pentax Of America, Inc. accounts for 60.5% of it on its own, with 10 other manufacturers making up the rest. Reporting peaked in 2019 at $49,032 and has fallen 99.9% since, to $25 in 2025. Among gastroenterology clinicians in TX 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.
Across 42 payments — averaging $4582.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$192,465 in reported general payments places this provider in the 95th percentile of 1,350 gastroenterology providers in Texas.
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.
Most prescribed under Part D
