The purpose of this legislation is to prevent the Secretary of Health and Human Services from putting into action a specific model called the WISeR model under the Medicare program. This model was intended to change how certain medical services are approved for Medicare beneficiaries, and the bill aims to stop this change from happening. The key provision of the legislation is straightforward: it explicitly prohibits the implementation of the WISeR model, which was designed to introduce prior authorization requirements for certain medical services.
