This legislation aims to prevent the implementation of the WISeR model within the Medicare program. It specifically targets an innovative payment and service delivery model proposed by the Secretary of Health and Human Services, identified as the "Wasteful and Inappropriate Services Reduction (WISeR) Model." The bill explicitly prohibits the Secretary from enacting this model, which was detailed in a July 1, 2025 Federal Register notice, or any substantially similar model . The core purpose is to block the introduction of a new prior authorization framework for certain Medicare services, ensuring such initiatives are not put into practice.
