The June 2018 Medicaid and CHIP Payment and Access Commission (MACPAC) Report to Congress included a chapter on Managed Long-Term Services and Supports (MLTSS). The chapter provides an overview of MLTSS, the growing role of managed care in long-term services and supports, reviews the results of MACPAC’s initial work in this area, and identifies gaps in our knowledge about what drives     success in MLTSS programs. It also includes highlights of reports describing state MLTSS programs and program outcomes. In addition, the report focuses on operational issues and the future of MLTSS.
