Oklahoma Medicaid Managed-Care Plans for Providers
Enrollments are billed 50% at the start and 50% at submission; everything else 100% at the start.
SoonerCare is run by the Oklahoma Health Care Authority. 567,698 people were enrolled in its 3 managed-care plans in 2024. To see their patients, a provider enrolls with SoonerCare through the OHCA Provider Portal, then applies to each plan separately.

How Joining Works in Oklahoma
First the state: SoonerCare enrollment through the OHCA Provider Portal, 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 Oklahoma Plan
Oklahoma Complete 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.
Humana Healthy Horizons of Oklahoma (Humana): Humana's Medicaid plans take participation requests through Humana's provider site for that state and credential from your CAQH ProView (DataSpring) profile.
Aetna Better Health of Oklahoma (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.
Also in Oklahoma: Medicare, SoonerCare and commercial credentialing.

Do I have to join every Oklahoma 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 SoonerCare enrollment first.
