How Joining Works in New Hampshire
First the state: New Hampshire Medicaid enrollment through the NH MMIS provider portal (Conduent), 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 New Hampshire Plan
New Hampshire Healthy Families (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.
AmeriHealth Caritas of New Hampshire (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.
WellSense 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 New Hampshire: Medicare, New Hampshire Medicaid and commercial credentialing.
