    Clinical & Coding Specifications

    Clinical Context

    A typical patient is an adult with limited mobility or without access to private transportation who requires scheduled non-emergency transport to and from a medical appointment across town or between states. For example, a 68-year-old Medicare beneficiary with congestive heart failure and mobility limitations requests a scheduled round-trip ride on a commercial bus carrier to attend a cardiology clinic visit located in a neighboring city. The workflow begins with the patient or case manager arranging the trip through a non-emergency transportation vendor or the patient’s managed care plan. The carrier confirms pickup and drop-off times, documents the passenger’s eligibility and route, and provides the ride. Trip documentation includes passenger name, date/time of service, origin and destination addresses, medical necessity indication (appointment type and provider), and any special assistance requested. Billing is submitted using HCPCS Level II code A0110 with an appropriate modifier to indicate circumstances such as attendant service, reduced services, or payer-specific requirements. Payers involved may include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare; each requires supporting documentation of the scheduled appointment and patient eligibility for non-emergency transportation benefits.
