What is ambulatory transportation in NEMT?

Updated 3 min read

Ambulatory transportation is non-emergency medical transportation for riders who can walk and sit in a regular vehicle seat, with little or no help from the driver. Trips run in sedans, minivans, or taxis, with no lift or ramp. It is the lowest-cost NEMT vehicle level and is usually billed with a taxi or mini-bus base code, such as A0100 or A0120, plus mileage.

What ambulatory means in NEMT

Ambulatory means the rider can walk. In NEMT it names the lowest vehicle level: the rider gets to the vehicle, sits in a standard seat, and wears the vehicle’s own seat belt. Virginia’s Medicaid handbook defines it as members who can get in and out of the vehicle on their own, with minivans and sedans as the usual vehicles.

A cane, walker, or crutches usually does not change the mode. The driver stores the device during the ride. What can change is the assistance level. A rider who walks but needs an arm to the front door is still ambulatory, booked with door-to-door help. Ask at booking about walkers and whether the rider can step up into a taller van, so the right vehicle shows up.

Some states split the level in two. Minnesota law separates unassisted transport (taxi or public transit) from assisted transport, where an NEMT provider carries a client who needs help. Each is a separate mode, and payment follows the assessed mode.

Who rides ambulatory, and when they move up

Most routine visits for riders who walk fit here: primary care, therapy, and dialysis for riders who leave treatment steady on their feet.

A rider can qualify for more than ambulatory even though they walk. New York’s rule (18 NYCRR 505.10) allows ambulette transport when a rider needs a walker or crutches and cannot use a taxi, bus, or private car. It also covers an otherwise ambulatory rider who is too weak after radiation, chemotherapy, or dialysis to use a taxi or bus. The level of service on the trip tells you which case you are running.

Vehicle and driver requirements

Ambulatory vehicles need no lift or ramp, but they still have to meet the program’s general vehicle rules. Virginia’s May 2026 requirements show what to expect:

  • Seat belts for every passenger, plus at least one seat belt extension.
  • A seat belt cutter within the driver’s reach, a first aid kit, and a secured fire extinguisher.
  • Inspection before the vehicle starts service, then every six months.
  • Taxi-plated vehicles licensed by the local taxi authority where one exists.

Driver rules come from the same contracts. Virginia requires a criminal background check, broker training, defensive driving, a valid license, and a motor vehicle record check. CareOregon lets drivers who only operate sedans take the ambulatory-only version of its required passenger safety course. Wheelchair van drivers must complete the securement portion.

How ambulatory trips are billed

There is no single ambulatory code. Programs choose from the HCPCS non-emergency codes:

CodeDescriptor (CMS)Common use
A0100Non-emergency transportation; taxiTaxi trips
A0120Mini-bus, mountain area transports, or other transportation systemsSedans and minivans run by NEMT providers
S0215Non-emergency transportation; mileage, per mileMileage on ambulatory trips
T2003Non-emergency transportation; encounter/tripPer-trip billing, where a payer uses it

Colorado bills mobility vehicles as A0120 and taxis as A0100, each with S0215 mileage for trips on or after July 1, 2025. Medi-Cal’s rate table (page updated August 2020) lists non-medical transportation under A0120 at a $17.65 maximum base allowance. Virginia and New York also let brokers send some ambulatory riders by transportation network company instead.

Frequently asked questions

Can a rider with a walker or cane ride ambulatory?
Yes, in most programs. The rider walks to the vehicle and sits in a regular seat, and the driver folds and stores the walker. NEMTAC's standard calls this curb-to-curb service with assistance. If the rider cannot use a taxi or car even with the device, some states allow a higher level. New York, for example, allows ambulette transport in that case.
Does an ambulatory trip need a wheelchair van?
No. Any passenger vehicle that meets the program's vehicle rules can run it. You can send a wheelchair van, but programs such as Minnesota's and Colorado's pay the level that was booked, so the trip still pays the ambulatory rate.
Are rideshare trips ambulatory transportation?
Often, yes. Several state programs let brokers send ambulatory riders by transportation network company, taxi, or bus pass. Virginia's NEMT manual lists transportation network companies as a mode, with DMAS permission, alongside taxis and public transit tickets.
