Indiana Medicaid Managed-Care Plans for Providers
Enrollments are billed 50% at the start and 50% at submission; everything else 100% at the start.
Indiana Medicaid (IHCP) is run by the Indiana Family and Social Services Administration. 1,608,993 people were enrolled in its 6 managed-care plans in 2024. To see their patients, a provider enrolls with Indiana Medicaid (IHCP) through the IHCP Provider Healthcare Portal (Gainwell), then applies to each plan separately.

How Joining Works in Indiana
First the state: Indiana Medicaid (IHCP) enrollment through the IHCP Provider Healthcare Portal (Gainwell), 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. 6 parent companies run plans here, and plans owned by the same company still contract state by state.
How to Join Each Indiana Plan
Anthem Blue Cross and Blue Shield (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.
Managed Health Services (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.
CareSource Indiana (CareSource): CareSource takes participation requests through its provider pages for each state and credentials 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.
Humana Healthy Horizons of Indiana (Humana): Humana's Medicaid plans take participation requests through Humana's provider site for that state and credential from your CAQH ProView (DataSpring) profile.
MDwise: 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 Indiana: Medicare, Indiana Medicaid (IHCP) and commercial credentialing.
