    HCPCS A0090: Non-Emergency Transportation, Per Mile

    HCPCS Level II code A0090 designates non-emergency transportation billed per mile when the vehicle is provided by an individual with a vested interest (such as a family member, self, or neighbor); the service type is non-emergency ground transportation and the typical site of service is community or patient residence transport where an individual driver transports the patient for non-urgent medical appointments or related needs.

    For related coverage guidance, see recent payer policy updates: Percutaneous Arteriovenous Fistula Creation, Dialysis Services (ESRD) Coverage and Provider Requirements, Intradialytic Parenteral Nutrition - Medical Policy.

    Clinical & Coding Specifications

    Clinical Context

    A typical patient scenario involves an adult or pediatric patient who requires non-emergency ground transportation to a medical appointment, diagnostic test, or scheduled treatment and is transported in a personal vehicle provided by a family member, neighbor, or other individual with a vested interest. For example, a patient with congestive heart failure attends a cardiology outpatient infusion appointment and a family member drives them 12 miles each way using a personal car. The clinical workflow begins when a clinician or care coordinator documents the medical need for transportation assistance in the patient record, confirms that non-emergency ambulance or vendor transportation is not required, and arranges for the private individual driver. Mileage is tracked from the patient pickup location to the medical facility and back, recorded in the encounter or transport log, and billed using the HCPCS Level II code A0090 with any applicable modifier(s). Supporting documentation includes the date of service, origin and destination addresses or miles, reason for visit, driver relationship, and clinical justification for non-ambulance transport (for example, mobility limitation, lack of other transportation, or clinical need for accompaniment). Payers such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare typically review medical necessity, mileage substantiation, and any program-specific policies for reimbursement of mileage to a privately provided vehicle.
