Distinct Medicare and Medicaid rules, funding streams, and service delivery systems can create barriers that increase costs and worsen outcomes for people who are jointly enrolled in the programs. We support correcting this fragmentation through policies that offer meaningful choice; reduce disparities in access to and quality of care; rely on active and informed enrollee participation; include robust safeguards and oversight; offer clear enrollee and provider education about options for accessing integrated care; establish unified grievance and appeals processes; ensure seamless access to data; and provide person-centered care coordination and care management.
