In Illinois, the state coordinates care for approximately 400,000 dual-eligibles through a mix of programs including Fully Integrated Dual Eligible Special Needs Plans (FIDE SNPs), HealthChoice Illinois Managed Long-Term Services and Supports (MLTSS), and, for some individuals, fee-for-service Medicaid or intellectual and developmental disability (IDD) waivers.
