Arizona has no statewide NEMT broker. AHCCCS health plans arrange rides, so you contract with each plan or the transportation vendor it subcontracts to.
Each AHCCCS plan sets its own transportation network; there is no single broker to credential with.
For the licensing steps, see NEMT licensing by state; for how brokers compare in other states, see the NEMT Broker Report Card. Arrangements change; confirm with the state Medicaid agency before you sign.
