Summary
Illinois MMAI program has transitioned to FIDE SNPs with updated enrollment verification systems. The Department's enrollment files now contain accurate FIDE SNP information, and specific health plan contract numbers and display names have been established for billing verification.
Action Required
Immediately: Billing team must update patient eligibility verification processes to check MEDI system for FIDE SNP enrollment information. Verify patients show enrollment in both 'Medicare Advantage' and 'Managed Care Organization' sections for full dual coverage, or only 'Medicare Advantage' for Medicare-only FIDE SNP coverage. Update contact lists with new provider and care coordination email addresses for each FIDE SNP plan. Reference the specific contract numbers and health plan display names when verifying benefits.
