Hawaii Medicaid Managed-Care Plans for Providers
Enrollments are billed 50% at the start and 50% at submission; everything else 100% at the start.
Med-QUEST is run by the Hawaii Department of Human Services. 432,125 people were enrolled in its 5 managed-care plans in 2024. To see their patients, a provider enrolls with Med-QUEST through the HOKU provider portal, then applies to each plan separately.

How Joining Works in Hawaii
First the state: Med-QUEST enrollment through the HOKU 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 Hawaii Plan
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.
Kaiser Permanente (Kaiser Permanente): Kaiser Permanente mostly delivers care through its own medical groups, so outside providers are added when Kaiser has a network need for the specialty and area.
Ohana Health Plan (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.
Hawaii Medical Service Association (HMSA), AlohaCare: 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 Hawaii: Medicare, Med-QUEST and commercial credentialing.
