Summary
Illinois is transitioning Medicare-Medicaid Alignment Initiative (MMAI) programs to Dual Eligible Special Needs Plans (D-SNP) with four participating plans. Long-term care providers need to verify their network status and use new plan codes in eligibility verification systems.
Action Required
Immediately: Long-term care providers must confirm their FIDE SNP network status with each health plan (Aetna, Humana, Meridian, Molina). Update eligibility verification systems to use new SNP plan codes: Aetna (23), Humana (10), Meridian (19), Molina (25) with site number 001 and exclusion code 2 for all plans. Contact affiliated MMAI plans for contracting questions or email HFS.DSNPInquiries@Illinois.gov for guidance.
