What this record shows

Medtronic accounts for 61.3% of it on its own, with 26 other manufacturers making up the rest. Reporting peaked in 2024 at $3,124 and has fallen 91.8% since, to $256 in 2025.
Across 81 payments — averaging $77.72 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
$6,295 in reported general payments places this provider in the 85th percentile of 125 nephrology providers in Nevada.
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.
