Overview

What is WISeR?

Importantly, WISeR does not change Medicare coverage or payment policy. It supports accurate, efficient compliance with existing National and Local Coverage Determinations.

The Wasteful and Inappropriate Service Reduction (WISeR) Model is a voluntary six-year CMS Innovation Center program designed to reduce unnecessary or inappropriate services in Original Medicare (Part A & B) for selected items and services. WISeR uses enhanced technologies—like AI and machine learning—combined with human clinical review to streamline decisions and protect beneficiaries and taxpayers. 

WISeR launches January 1, 2026 and runs through December 31, 2031 in six pilot states: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. In New Jersey, WISeR prior authorization and pre-payment medical review activities are administered through Novitas (Jurisdiction H) with Genzeon providing the technology platform and operational support.

Program Process

How the WISeR Program Works

WISeR is built to make reviews more predictable and less burdensome, while aligning with existing Medicare rules.

WISeR Request Process:

  1. Provider submits a prior authorization (PA) request for a WISeR-included service rendered in New Jersey.
  2. Technology-enhanced review flags completeness.
  3. Review checks documentation against current Medicare coverage criteria.
  4. Human clinical validation occurs when needed to confirm medical necessity.
  5. Determination returned within CMS-defined timeframes.

If a claim is submitted without required PA, it may enter pre-payment medical review.
