Payments from drug & device makers
What this record shows
This record is dominated by education: $31,000 of the $39,583 with a category attached, or 78.3%. Intuitive Surgical accounts for 90.5% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2019 at $26,093 and has fallen 99.9% since, to $26 in 2025. Among surgical oncology clinicians in TX 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 75 payments — averaging $527.77 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$39,583 in reported general payments places this provider in the 90th percentile of 191 surgical oncology 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

Paid to pharmacies, not to this prescriber.
