What taxonomy code does a NEMT provider use?
A taxonomy code is a 10-character code from the NUCC Health Care Provider Taxonomy that describes what type of provider you are. The code built for NEMT vans is 343900000X, Non-emergency Medical Transport (VAN). Other transportation codes cover taxis, private vehicles, secured transport, brokers, and transportation network companies. You choose codes on your NPI application, and some state Medicaid programs tell you which one to use on claims.

The transportation taxonomy codes
NUCC’s Transportation Services grouping holds the codes NEMT companies choose from. This table uses version 26.1, effective July 1, 2026.
| Code | NUCC name | What it describes |
|---|---|---|
| 343900000X | Non-emergency Medical Transport (VAN) | A land vehicle that meets special height, clearance, access, and seating needs for non-emergency trips |
| 343800000X | Secured Medical Transport (VAN) | Vehicles equipped for enhanced safety, security, and restraint, staffed by people trained to work with patients in a mental health or substance use crisis |
| 344600000X | Taxi | A commercial vehicle for non-emergency trips that meets local, county, or state taxi rules |
| 347C00000X | Private Vehicle | An individual paid to provide non-emergency rides in a vehicle they own or lease |
| 342000000X | Transportation Network Company | A rideshare company that provides prearranged or contracted NEMT through an app or website (added January 1, 2021) |
| 347E00000X | Transportation Broker | An organization that arranges rides for people with no other means of transportation to medical care |
| 347B00000X | Bus | A licensed public or private bus service |
| 3416L0300X | Land Ambulance | A ground ambulance, under the Ambulance classification (341600000X) |
For a person rather than a company, NUCC also has 172A00000X, Driver, under Other Service Providers.
How taxonomy codes work
A taxonomy code describes what kind of provider you are, not what you did on a given trip. Each code is 10 characters and sits in three levels: grouping, classification, and specialization. NUCC maintains the set, and each version takes effect on January 1 or July 1.
Three rules matter most:
- You choose it yourself. NUCC says codes are self-selected, based on the provider’s own judgment of what fits.
- It is not a license. Scope of licensure is outside the code set, so permission to operate still comes from your state and local rules.
- Payers can require a specific code. The code travels on your NPI record and on claims, and a state manual can tell you which one to use.
Texas is a good example of rule 3. Its Medical Transportation Program handbook tells individual drivers reimbursed per mile, and transportation network companies, to put 347C00000X, Private Vehicle, on their claims, even though NUCC has a separate TNC code. Check your state’s current manual before billing rather than assuming the NUCC name decides it.

An example
A new company with four wheelchair vans applies for an organization NPI. On the application it picks 343900000X, Non-emergency Medical Transport (VAN), because the definition matches its vehicles. It then enrolls with its state Medicaid program under the state’s transportation provider type. Before billing, it checks the state’s transportation manual for the taxonomy code the state expects on claims, and it updates its NPI record if that code is missing. The steps to enroll are in how to become a Medicaid transportation provider.
Frequently asked questions
- Can a NEMT company have more than one taxonomy code?
- Yes. NUCC says providers choose the code or codes that best describe them. A company that runs both wheelchair vans and licensed taxis could carry both classifications. Use the one your state or broker asks for on each claim.
- Is 343900000X only for wheelchair vans?
- No. NUCC defines it as a land vehicle able to meet special height, clearance, access, and seating needs for non-emergency trips. The definition does not name wheelchairs, and it notes the vehicle may or may not have to meet local or state rules.
- Which taxonomy code do NEMT brokers use?
- 347E00000X, Transportation Broker. NUCC describes it as an organization that provides transportation for people who need access to medical care and have no other means of transportation, including wheelchair vans, taxis, stretcher cars, bus passes, and secured transport.
