Michigan Medicaid managed care operates through the Comprehensive Health Care Program (CHCP), administered by MDHHS, first implemented in 1997 and currently under nine-plan contracts effective Oct. 1, 2024 through Sept. 30, 2029 (with three one-year renewal options), covering roughly 2.2 million beneficiaries. The dual-eligible population moved to a new coordinated-care model, MI Coordinated Health, on Jan. 1, 2026, replacing the outgoing MI Health Link demonstration. Specialty behavioral health remains carved out of CHCP entirely, run through a 10-region Prepaid Inpatient Health Plan (PIHP) system whose planned 2026 restructuring into 3 regions was formally withdrawn by MDHHS in early 2026 after a court ruled the restructuring RFP conflicted with the Michigan Mental Health Code; the existing 10-PIHP structure remains in place, not a pending or unsettled question.
Nine Medicaid Health Plans (MHPs) hold CHCP contracts effective Oct. 1, 2024: Aetna Better Health, Blue Cross Complete, HAP CareSource, McLaren Health Plan, Meridian Health Plan, Molina Healthcare, Priority Health Choice, UnitedHealthcare Community Plan, and Upper Peninsula Health Plan (the sole plan serving the UP). Nursing facility residents, MI Choice waiver participants, and MI Coordinated Health enrollees do not enroll in a standard MHP.
Not integrated into standard MHP managed care. The MI Choice Home and Community Based Services waiver, Michigan's primary community-based long-term-care program for older adults and adults with physical disabilities, operates as its own carved-out program outside the nine CHCP MHPs; MI Choice participants are excluded from standard MHP enrollment. Nursing facility residents are likewise excluded from standard MHP enrollment. The state's I/DD and other 1915(c) HCBS waivers similarly operate as their own carved-out programs rather than being integrated into CHCP's MHP structure.
Not integrated into managed care
Fully carved out of the nine CHCP MHPs. Specialty behavioral health, substance use disorder, and I/DD services are instead administered through a 10-region Prepaid Inpatient Health Plan (PIHP) system, with the PIHPs subcontracting to roughly 46 county-based Community Mental Health Services Programs (CMHSPs) for direct service delivery. MDHHS proposed consolidating the 10 PIHP regions into 3 under a competitive procurement model in 2025, but rescinded that proposal after a court found it conflicted with the Michigan Mental Health Code; the existing 10-region PIHP/CMHSP structure remains in place.
Carved out
Dental is generally an in-plan MHP benefit. Adult dental benefits were expanded in 2023, though access and network adequacy vary by plan; each MHP publishes its own dental network. Michigan has no single statewide dental administrator vendor; dental is managed per-MHP rather than through one carved-out statewide vendor.
Pharmacy is carved in and administered per-MHP; each plan maintains its own preferred drug list, per consumer-facing plan-selection guidance directing members to check each plan's own formulary. Michigan has no single statewide PBM vendor or centrally mandated preferred drug list.
Non-emergency medical transportation (NEMT) is contracted per-MHP, not through one statewide broker. A current MDHHS document identifies Medical Transportation Management, Inc. (MTM) as Molina Healthcare of Michigan's NEMT vendor. Sources disagree on the broader picture: a third-party NEMT-industry rate guide describes ModivCare as Michigan Medicaid's statewide broker, which conflicts with MDHHS's own document naming MTM for Molina specifically. Which characterization applies to the other eight MHPs, or whether both vendors operate for different plans, is unclear.
CHAMPS (Community Health Automated Medicaid Processing System) is Michigan's Medicaid Management Information System, operated by Acentra Health, serving as the state's provider enrollment, eligibility, prior authorization, and claims platform for roughly 2.6 million residents. Michigan's MMIS runs on a multi-state cloud governance model shared with Illinois; both states use a common underlying platform to reduce costs.
