Medicaid Provider Type Codes for NEMT Companies, State by State

When a state Medicaid program enrolls your company, it files you under a provider type, and often a specialty under that type. That type decides which billing codes you may use, what you had to prove to get in, and which rules the state checks you against. Every claim you send is checked against it.

What a Medicaid provider type is

Every state Medicaid program sorts the providers it enrolls into types, and most add specialties under each type. You pick your type and specialties on the application, and the state confirms them when it approves you. From then on, they decide which codes you may bill, which documents you keep current, whether you pay an application fee, and how closely you are screened.

Federal screening rules are written around the type. Under 42 CFR 455.450, the state must confirm you meet its requirements for your provider type before it enrolls you, and run database checks before and after enrollment to make sure you still meet the criteria for that type. Each state sets the risk level for its own NEMT types; see Medicaid provider risk levels. Under 42 CFR 455.470, an enrollment freeze can cover a whole provider type, so your type also decides whether a freeze stops you; see Medicaid enrollment moratorium.

States set their own rules for choosing:

• Florida asks every applicant for a provider type and at least one specialty with a matching taxonomy code (Provider Enrollment Policy, February 2026).
• Indiana allows one provider type per enrollment and any number of specialties under it. A second provider type needs a second application and its own Provider ID (Provider Enrollment module, September 8, 2026).

Your provider type is not the taxonomy code on your NPI. You pick the taxonomy yourself in NPPES, and it stays the same in every state. The provider type belongs to one state’s program, like your Medicaid provider number.

NEMT provider type codes by state

States label transportation companies in very different ways, from a two-digit type with three-digit specialties to a category of service.

State	Provider type	NEMT choices under it
Arizona	28, Non-Emergency Transportation Providers	Category of service 31, non-emergency transportation
Indiana	26, Transportation Provider	262 bus, 263 taxi, 264 ambulatory, 265 nonambulatory, 266 family member, 267 TNC, 269 broker fleet
Florida	41 non-emergency, 43 taxi, 44 government, 45 private, 46 non-profit, 47 multi-load private	One specialty each, such as 941 Non-Emergency Transport under type 41
Texas	MT, the Medical Transportation Program type on every claim	Specialty TS for demand response companies and TNCs, T4 for individual participants
New York	Category of service	0602 ambulette, 0603 taxi (upstate), 0605 livery (New York City), 0606 OPWDD, 0609 TNC
North Carolina	Organization or atypical organization	The taxonomy you enroll under, such as 343900000X for NEMT vans
Ohio	83, Wheelchair Van	Specialty 830, wheelchair van

The dates behind the table: Arizona’s packet was revised in September 2026, Indiana’s module was published September 8, 2026, Florida’s policy is dated February 2026, Texas’s handbook is the October 2026 edition, New York’s enrollment page was updated in May 2026, North Carolina’s permission matrix is dated August 16, 2026, and Ohio’s managed care services form, ODM 10234, was revised in March 2024. Ambulances have their own codes in each state, such as Indiana’s specialty 260, Florida’s type 40, and Ohio’s type 82. Ohio rule 5160-15-21 (effective July 1, 2021) lets a wheelchair van provider both run and bill rides.

What the type asks of you

The type also sets your paperwork. Four examples:

• Arizona, type 28. No NPI is required. You send vehicle insurance and registration, a signed type 28 profile form, an ADOT vehicle for hire permit, and each driver’s full legal name, birth date, Social Security number, and job dates. The owner completes the AHCCCS NEMT certification training and uploads the certificate, and driver changes go into the enrollment portal within 30 days.
• Indiana, specialties 264 and 265. A for-profit company sends its Motor Carrier Services certificate from the Indiana Department of Revenue or its USDOT authority. Both specialties also need proof of insurance, a surety bond of at least $50,000 that lasts at least three years (501(c)(3) nonprofits and a few others are exempt), a copy of every driver’s license, and each driver’s name, Social Security number, and birth date with three signed attestations. A taxi under 263 may not carry riders outside the area its city license covers, so a taxi that crosses that line enrolls as a common carrier. Specialty 269 needs approval from the state before you apply. After you enroll, you still contract with Verida for fee-for-service trips and with each health plan’s broker.
• Florida, transportation types. Transportation applicants send a local license and proof of liability insurance of $100,000 per person and $200,000 per incident, and private and taxi companies add an operator’s license. Non-emergency, multi-load, and taxi providers also post a surety bond on AHCA Form 5000-1064, unless they contract through the transportation coordinator.
• New York, categories 0602 to 0609. You pick your category of service in the Provider Services Portal and pay the application fee, $750 on the page updated in May 2026. Every non-medical transportation applicant also needs a letter of support from Medical Answering Services; new applications sent after April 15, 2024 without one are rejected. An application not submitted within 45 days of starting it is deleted.

In Texas, demand response companies and TNCs are the two transportation types that enroll with TMHP. Individual transportation participants register but do not enroll as Medicaid providers, and TMHP gives each one an atypical provider identifier and a taxonomy code to use on claims.

How a wrong provider type shows up on a claim

Payers check each claim line against your enrollment. When the code you bill is not one your type and specialty may bill, the line can be denied, and the remittance carries a national reason code. Three fit this kind of mismatch: 8 (the procedure code does not fit the provider type or specialty), 170 (denied when this type of provider bills it), and B7 (the provider was not eligible to be paid for this service on this date). The fixes for each are on the claim adjustment reason codes page.

Indiana shows how tight the link is. Its Transportation Services Codes list (published July 3, 2025) gives each specialty its own table of billable codes. The table for 265, nonambulatory, includes A0130, the wheelchair van trip, and A0425 U5, wheelchair mileage. It also lists T2003 and A0425 U3, the trip and mileage codes for riders who walk. The table for 264, ambulatory, lists those two as well, but no wheelchair codes.

Here is a billing example. Say your Indiana company enrolled under 264 only, to carry riders who walk. A dialysis clinic asks you to take a member who must travel in a wheelchair, and you bill A0130 for the trip. A0130 is not on your specialty’s list, so the line does not match your enrollment. Fixing a box on the claim will not help. The fix is an enrollment that includes 265, approved before you run that kind of trip, and since Indiana does not allow specialty changes for transportation providers, that is a decision to make on day one.

How to choose the right type when you apply

1. Find your state’s list. Indiana’s Provider Enrollment module, Florida’s Appendix A, Ohio’s form ODM 10234, and New York’s transportation enrollment page name the transportation types. Elsewhere, read the state’s provider enrollment manual or ask its enrollment office.
2. Match every service you run. Pick a specialty for each kind of trip: riders who walk, wheelchair riders, stretcher riders, taxi, or rideshare. Then read the code list for each specialty you pick.
3. Plan for growth now. Indiana does not permit specialty changes for transportation providers, and a new type means a new application. Ask how adding a service works before you choose.
4. Check what the type brings. The type sets your fee, your screening, and your document list. Arizona’s type 28, for example, brings a site visit and fingerprint checks.
5. Line up your taxonomy. Choose an NPI taxonomy that fits the state type. Florida ties each specialty to a taxonomy, and North Carolina enrolls you by it.
6. Bill only what your approval shows. Keep the approval letter with your billing setup, check your state’s code list for each specialty, and give your type and specialty to every broker that asks.
