Credentialing in Idaho

Idaho routes Medicaid behavioral health through a single statewide carve-out, the Idaho Behavioral Health Plan (IBHP), administered by Magellan Healthcare of Idaho, spanning inpatient and outpatient mental health and SUD levels of care. A behavioral health provider must enroll with Idaho Medicaid (Gainwell) AND join Magellan's IBHP network; claims and authorizations run through Availity Essentials.

Idaho Medicaid is run by the Idaho Department of Health and Welfare (IDHW); the fiscal agent portal is Gainwell Technologies at idmedicaid.com ("Idaho Medicaid Health PAS OnLine"). Per the portal: "To enroll with Idaho Medicaid, providers are required to complete registration for a Trading Partner Account and then complete the electronic Provider Enrollment Application." The secure account then handles enrollment, disenrollment, reactivation, revalidation when due, eligibility checks, authorization lookups, and claim processing.
