The bill aims to reform prior authorization requirements for medical services and prescription drugs under the Medicare Advantage program. It mandates a review of current prior authorization processes by the Secretary of Health and Human Services by January 1, 2027, to identify high-reimbursed items and services with excessive approval steps. Based on the audit findings, standardized requirements will be established by May 1, 2028, across all Medicare Advantage plans. Additionally, there are exemptions for providers participating in certain risk models, allowing them to bypass prior authorization requirements. This bill seeks to streamline and standardize prior authorization for Medicare Advantage plans, potentially reducing administrative burdens for patients and providers.
