Medicaid billing and authorization checklist for Maricopa County
Provider teams working in Maricopa County, Arizona should verify three things before submitting referrals, authorizations, or claims: the local behavioral health authority or access point, the state Medicaid or managed-care authorization path, and the official billing or provider-manual source for the service type.
For each referral or claim, confirm the payer route, service level, provider enrollment status, NPI and taxonomy, diagnosis and medical-necessity documentation, required CPT or HCPCS code, authorization window, timely-filing rule, and whether the workflow runs through county access, a managed care plan, a behavioral health ASO, or fee-for-service Medicaid.
Whether your team is verifying Maricopa County behavioral health access, Medicaid eligibility, crisis services, community mental health routing, or substance use treatment coverage, start with the official sources linked here, then confirm the member's payer, plan assignment, and service-specific authorization route.
Check official state and county sources before sending referrals, requesting authorizations, submitting documentation, or billing Medicaid services.
Arizona providers should check the applicable contractor portal and use the AHCCCS Online Provider Portal for fee-for-service prior authorization when that path applies.
