WISeR (Wasteful and Inappropriate Service Reduction) Model

Notice:
WISeR Model Application Period Open

Applications to participate in the WISeR Model are due by 11:59 PM ET July 25, 2025. Go to the RFA. Potential model participants are required to apply through the application portal.

The Wasteful and Inappropriate Service Reduction (WISeR) Model will help protect American taxpayers by leveraging enhanced technologies, such as Artificial Intelligence (AI) and Machine Learning (ML), along with human clinical review, to ensure timely and appropriate Medicare payment for select items and services. The voluntary model will encourage care navigation, encouraging safe and evidence-supported best practices for treating people with Medicare. WISeR will run for six performance years from January 1, 2026 to December 31, 2031. The application period opened on June 27, 2025. 

Key Points
  • Problem: Waste in health care can not only harm patients but also contributes to up to 25% of health care spending in the United States. Wasteful, low-value services often have limited clinical evidence of effectiveness, may not align with an individual’s specific health condition or needs, or can lead to complications and further unneeded services.
  • Solution: The WISeR Model will help reduce clinically unsupported care by working with companies experienced in using enhanced technologies to expedite and improve the review process for a pre-selected set of services that are vulnerable to fraud, waste and abuse.
  • Outcomes: The WISeR Model will help ensure people with Medicare receive the most appropriate care that supports the best health outcomes while decreasing costs and easing administrative burden on providers and suppliers who go through the prior authorization process.
  • Strategy: The WISeR Model empowers patients to partner with their health care providers on the most clinically appropriate care plan; protects the taxpayer by decreasing fraud, waste and abuse; and focuses providers on care that has the most impact on the well-being of people with Medicare.
