The main purpose of this legislation is to update how Medicare sets payments for doctors and healthcare providers. Specifically, it aims to establish a new method for calculating the payment rates under the Medicare physician fee schedule, which determines how much Medicare pays for various medical services. The change is intended to ensure that these payment rates reflect the economic conditions affecting healthcare providers. Key provisions of the legislation include a requirement that starting in 2026, the payment rates will be adjusted based on the Medicare Economic Index (MEI).
