HCPCS Level II T2004: Non-emergency Commercial Multi-passenger Transport
HCPCS Level II code T2004 represents non-emergency transport provided by a commercial carrier for multiple passengers. This code captures group ground conveyance services used for scheduled, non-urgent travel where a commercial multi-passenger vehicle conveys two or more individuals. Nationally, non-emergency transportation codes like T2004 matter because they standardize billing for community and commercial mobility services that support outpatient care access, clinic attendance, and discharge planning.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical and billing context for T2004, typical sites of service, and the common modifiers associated with this service line. The publication outlines what stakeholders should expect in terms of code use, payer coverage considerations, and common operational contexts where multi-passenger commercial transport is applied.

Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves a non-emergent, scheduled intercity transfer of multiple outpatient clients by a commercial carrier (for example, a wheelchair-accessible shuttle contracted by a hospital system) from an ambulatory infusion center to a rehabilitation facility following a planned course of treatment. The patients are clinically stable, do not require advanced life support, and can be transported together in a multi-pass arrangement where the vehicle makes multiple stops to pick up or drop off patients. The clinical workflow begins with discharge planning or care coordination scheduling the multi-pass commercial transport using billing code T2004, confirming patient mobility and assistance needs, documenting the pickup and drop-off locations, and recording any clinical observations during transport (oxygen use, mobility assistance, communication needs). The transport order is cross-checked against facility discharge instructions, insurance authorization is obtained if required, and the commercial carrier documents the trip details, passenger manifests, and any incidents for inclusion in the patient medical record and billing submission.
