Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $508,327 of the $597,461 with a category attached, or 85.1%. Medtronic accounts for 99.3% of it on its own, with 14 other manufacturers making up the rest. Reporting peaked in 2020 at $508,914 and has fallen 99.6% since, to $2,044 in 2025. Among nephrology 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 55 payments — averaging $10,863 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
$597,461 in reported general payments places this provider in the 95th percentile of 259 nephrology 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.
Most prescribed under Part D

| Calcium Acetate | 16 | $1,549 |
