This brief reviews the new renewal requirements for Medicaid and CHIP that are designed to maintain continuity of coverage for eligible individuals. It provides an overview of state implementation of the new renewal policies and considers the potential role managed care plans can play in supporting renewals. Key findings include: some aspects of the simplified renewal policies have not yet been fully implemented due to a range of challenges; some states, including Washington and Rhode Island, have successfully implemented the new policies and achieved high retention rates with more than nine in ten enrollees successfully renewed; and, managed care plans can support renewals by reminding members to renew and providing direct assistance with the renewal process; however, plans identified challenges to supporting renewal.
