Summary & Overview
HCPCS A0090: Non-Emergency Transportation, Per Mile (Private Vehicle)
HCPCS Level II code A0090 denotes non-emergency transportation reimbursed per mile when the vehicle is provided by an individual with a vested interest, such as a family member, neighbor, or the patient. Nationwide, this code matters for programs and payers that cover non-emergency medical transportation (NEMT) because it specifies a mechanism for compensating private individuals rather than commercial carriers. Use of A0090 affects cost management, beneficiary access, and documentation practices for ambulatory and outpatient visits that require transport but are not emergent.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a clear understanding of what services qualify under the code, how typical sites of service and service types align with coverage policies, and where to look for benchmark reimbursement approaches. The publication summarizes common billing considerations, the role of A0090 in coordinating non-emergency transport benefits, and practical policy context relevant to national payer programs. Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes is noted where applicable.
Billing Code Overview
HCPCS Level II code A0090 describes non-emergency transportation billed per mile when the vehicle is provided by an individual with a vested interest (for example, a family member, self, or neighbor). The service involves transporting a patient for non-emergent medical-related purposes where the driver is not a commercial transportation vendor.

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.
