Provider Notice issued 01/09/2026

Important Updates on the Medicare Medicaid Alignment Initiative (MMAI) transition to Dual Eligible Special Needs Plan (D-SNP)

This notice provides updates regarding the transition of the Illinois Medicare-Medicaid Alignment Initiative (MMAI) program to fully integrated dual eligible special needs plans (FIDE SNPs) and the process for verifying FIDE SNP enrollment.

Department Enrollment Systems

***UPDATE: Until further notice, if the Department’s enrollment file (e.g. MEDI) lists a FIDE SNP in the Medicare Advantage section and a Health Choice Illinois (HCI) plan in the Managed Care Organization section, the FIDE SNP is the correct plan.  See MEDI screen print below as an example.  Please note that FIDE SNP enrollment may change monthly because members can switch monthly. Providers should submit claims to the FIDE SNP and not the HCI plan listed.

*Please note that the special information listed under the Managed Care Organization is incorrect if the member is enrolled in a FIDE SNP.

Per Provider Notice issued 12/24/2025, FIDE SNPs have the most accurate enrollment information. The reason is that the health plans, not HFS, enroll members in the FIDE SNP program.  The Department encourages all stakeholders to verify enrollment information with the FIDE SNPs.  For detailed instructions on how to contact the FIDE SNPs to verify enrollment, please refer to the Provider Notice issued 12/24/2025.

The Department is working on a manual reconciliation process to correct the inaccurate HCI plan enrollment information. When the reconciliation process is finalized, the Department will issue an updated provider notice.
