Summary & Overview
HCPCS A0110: Non-Emergency Bus or Carrier Transportation
HCPCS Level II code A0110 denotes non-emergency transportation by bus or intra- or interstate carrier. Nationally, this code is used to bill scheduled, non-urgent transport services for individuals who require conveyance but not medical transport with emergency or medical monitoring. The code matters as payers and benefit administrators evaluate coverage for non-emergency transportation services that affect access to care, social determinants of health programs, and transportation benefit design.
Key payers commonly associated with coverage decisions for non-emergency transport include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. This publication provides a concise overview of the code’s clinical and service context, typical sites of service, common modifiers and administrative details (when available), and how the code fits into broader non-emergency medical transportation policies.
Readers will learn the definition and intended use of A0110, the typical clinical/service scenarios in which it is applied, which payers are relevant for coverage considerations, and what content is unavailable in the input. The piece outlines benchmarking and policy-relevant topics to consider when reviewing coverage of non-emergency bus or carrier transportation in national payer programs.

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.
