A0100: Non-Emergency Transportation; Taxi

Definition
The HCPCS (Healthcare Common Procedure Coding System) code used to bill for Non-Emergency Transportation; Taxi. It covers curb-to-curb transportation for ambulatory passengers.

Overview

Why it Matters

It is one of the most common billing codes for NEMT. Using this code implies the vehicle does not need a wheelchair lift and the driver is not an EMT.

How it Works

A provider submits a claim with code A0100. The unit of service is typically "per trip" (sometimes per mile depending on state contracts). It confirms the patient was ambulatory and a lower-cost vehicle was used.

Code Comparison

Comparison: A0100 vs. A0130

A0100 is for a Taxi/Livery (Ambulatory patient). A0130 is for a Wheelchair Van (Non-ambulatory patient). A0130 reimburses at a higher rate due to the specialized equipment required.

Common Questions

  • Upcoding: Billing A0130 (Wheelchair) for a patient who walked into a sedan (should be A0100), which is fraud.
  • Missing Modifiers: Submitting A0100 without origin/destination modifiers (e.g., RH - Residence to Hospital).
  • Verify patient mobility status during intake to ensure A0100 is the correct code.
  • Ensure the vehicle used is legally licensed as a taxi/livery vehicle if required by the specific payer's A0100 definition.
