For non-emergency ambulance transportation services rendered to a client, ambulance providers may coordinate the nonemergency ambulance prior authorization request between the requesting provider, which may include a physician, nursing facility, healthcare provider, or other responsible party. Ambulance providers may assist in providing necessary information such as their National Provider Identifier (NPI) number, fax number, and business address to the requesting provider. However, the Non-emergency Ambulance Prior Authorization Request form must be signed and dated and submitted by the Medicaid-enrolled requesting provider, not the ambulance provider.
