Enrollments are billed 50% at the start and 50% at submission; everything else 100% at the start.
Michigan Medicaid is run by the Michigan Department of Health and Human Services. 2,362,189 people were enrolled in its 9 managed-care plans in 2024. To see their patients, a provider enrolls with Michigan Medicaid through CHAMPS, the Community Health Automated Medicaid Processing System, then applies to each plan separately.

How Joining Works in Michigan
First the state: Michigan Medicaid enrollment through CHAMPS, the Community Health Automated Medicaid Processing System, which gives you the Medicaid ID every plan asks for. Then the plans: each takes its own participation request and credentials you from your CAQH ProView (DataSpring) profile. 7 parent companies run plans here, and plans owned by the same company still contract state by state.
How to Join Each Michigan Plan
Meridian Health Plan of Michigan (Centene): Centene runs this plan alongside its Ambetter and Wellcare products. Each Centene plan takes its own contract request on the plan's provider website, credentials from your CAQH ProView (DataSpring) profile, and will not load a provider without the state Medicaid ID.
Molina Healthcare of Michigan (Molina Healthcare): Molina credentials each state separately. The contract request goes through the state's Molina provider site and requires an active state Medicaid enrollment; credentialing uses your CAQH ProView (DataSpring) profile.
Blue Cross Complete of Michigan (Independence Health Group): Plans in the AmeriHealth Caritas family take participation requests on each plan's own provider website and credential from your CAQH ProView (DataSpring) profile.
UnitedHealthcare Community Plan (UnitedHealth Group): UnitedHealthcare Community Plans use UnitedHealthcare's provider onboarding: a participation request on the UnitedHealthcare provider site, credentialing from your CAQH ProView (DataSpring) profile, then a state-specific Community Plan agreement.
Aetna Better Health of Michigan (CVS Health): Aetna Better Health plans each have a state-specific "Join our network" request on aetnabetterhealth.com. They are separate from Aetna's commercial network, so an Aetna commercial contract does not carry over.
HAP CareSource (CareSource): CareSource takes participation requests through its provider pages for each state and credentials from your CAQH ProView (DataSpring) profile.
McLaren Health Plan, Priority Health Choice, Upper Peninsula Health Plan: This plan is run in-state rather than by a national carrier, so participation requests go to the plan's own provider relations or contracting team, listed on its provider website.
Also in Michigan: Medicare, Michigan Medicaid and commercial credentialing.
