Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (51.5%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. Boston Scientific accounts for 76.5% of it on its own, with 32 other manufacturers making up the rest. Reporting peaked in 2021 at $67,433 and has fallen 80.7% since, to $13,039 in 2025. Among interventional pain medicine clinicians in AZ 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 957 payments — averaging $243.09 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$232,637 in reported general payments places this provider in the 95th percentile of 64 interventional pain medicine providers in Arizona.
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.
