Payments from drug & device makers

What this record shows

This record is dominated by speaking fees: $118,375 of the $153,893 with a category attached, or 76.9%. Aurinia Pharma U.S., Inc. accounts for 85.8% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2021 at $59,771 and has fallen 93.8% since, to $3,724 in 2025. Among nephrology clinicians in NJ 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.

Who reported the general payments

Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

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

$153,893 in reported general payments places this provider in the 95th percentile of 413 nephrology providers in New Jersey.

Medicare billing

Part B allowed, 2024
$93,449
Medicare patients
198
Services billed
784

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.
