Approximately 12 million people in the United States are dually eligible for Medicare and Medicaid. Because dual-eligible individuals and health plans serving this population must navigate two disparate coverage programs, their care is often fragmented and uncoordinated, and managed care plans may lack the ability to effectively manage the “whole person” across the two programs. While these problems are years old, the Centers for Medicare & Medicaid Services (CMS) and states are newly emphasizing a more integrated solution that puts a greater focus on managed care plans addressing the issue: Medicare Advantage dual-eligible special needs plans (D-SNPs), especially those considered “fully integrated” dual-eligible (FIDE) plans.
