Summary & Overview
HCPCS A0100: Non-Emergency Transportation, Taxi
HCPCS Level II code A0100 denotes non-emergency taxi transportation for patients requiring ground transit to and from covered healthcare-related destinations. This code matters nationally as a common rural and urban mobility option for patients without private transportation, and it intersects with access, utilization, and nonemergency medical transportation (NEMT) policy. Coverage and payment for taxi services can affect appointment adherence and total cost of care for outpatient and community-based services.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what A0100 represents, how it is categorized within HCPCS Level II, and which payers commonly address non-emergency taxi transport in coverage policies. The publication summarizes national benchmarks and payer approaches, highlights relevant policy considerations affecting NEMT, and provides clinical context for use cases where taxi transport is billed instead of other NEMT modes.
The report is intended for billing managers, policy analysts, and payers seeking a practical reference on code use, payer coverage patterns, and the clinical scenarios driving taxi-based transportation claims. Data not available in the input where specific modifiers, taxonomies, ICD-10 pairings, and related codes would otherwise be listed.

Clinical & Coding Specifications
Clinical Context
A patient with limited mobility or without personal transportation requires a non-emergency trip to an outpatient clinic for a scheduled follow-up visit. The patient calls the medical office to arrange transportation; the office authorizes a taxi dispatch to carry the patient from their residence to the clinic and back after the appointment. The transport is not urgent, does not require medical personnel or stretcher equipment, and the patient is ambulatory or can sit in a standard taxi. Typical workflow: the clinic verifies eligibility for non-emergency transportation, documents the pick-up and drop-off addresses, documents reason for visit and need for taxi, obtains any required prior authorization, records the date/time and fare, and bills the payer using HCPCS Level II code A0100 for the taxi trip. Billing includes appropriate modifier(s) to indicate special circumstances, and the clinical chart documents the visit and transportation arrangement for audit and medical necessity review.
