For non-emergency ambulance transportation, the responsibility for obtaining prior authorization typically lies with the requesting provider. This may include physicians, nursing facilities, healthcare providers, or other authorized parties. Ambulance providers can support the process by sharing essential details such as their National Provider Identifier (NPI), fax number, and business address with the requesting provider. However, it is important to note that the Non-Emergency Ambulance Prior Authorization Request Formmust be completed, signed, and submitted by the Medicaid-enrolled requesting provider—not the ambulance provider.
