Missouri Medicaid Managed-Care Plans for Providers
Enrollments are billed 50% at the start and 50% at submission; everything else 100% at the start.
MO HealthNet is run by the Missouri Department of Social Services. 1,021,946 people were enrolled in its 3 managed-care plans in 2024. To see their patients, a provider enrolls with MO HealthNet through the Missouri Medicaid Audit and Compliance (MMAC) provider enrollment application, then applies to each plan separately.

How Joining Works in Missouri
First the state: MO HealthNet enrollment through the Missouri Medicaid Audit and Compliance (MMAC) provider enrollment application, 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. 3 parent companies run plans here, and plans owned by the same company still contract state by state.
How to Join Each Missouri Plan
Home State Health (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.
Healthy Blue (Elevance Health): Elevance Health plans take participation requests through the plan's provider site for that state, most of them now inside Availity Essentials, and credential from your CAQH ProView (DataSpring) profile. Each state is its own contract.
UnitedHealthcare (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.
Also in Missouri: Medicare, MO HealthNet and commercial credentialing.

Do I have to join every Missouri Medicaid plan?
No. Each plan is a separate contract. Practices usually start with the two or three largest plans in their county, then add others as patients ask for them. All of them require MO HealthNet enrollment first.
