TL;DR

The NAICS code for non-emergency medical transportation is 485991 (Special Needs Transportation, Local). It covers wheelchair vans, stretcher cars, and ambulette services that don't provide emergency medical care. You'll need it for your EIN application, state Medicaid provider enrollment, business insurance, and most broker credentialing packets from Modivcare, MTM, Access2Care, or SafeRide.

What is the NAICS code for non-emergency medical transportation?

The code is 485991, officially titled "Special Needs Transportation, Local." The U.S. Census Bureau defines this industry as establishments that provide local, short-distance transportation for the disabled or elderly, typically using specially equipped vehicles like wheelchair vans, and it explicitly notes this is transportation "not using ambulances". That last part matters more than people think. NAICS 485991 sits inside the broader Transit and Ground Passenger Transportation sector (subsector 485), which is a different branch than Ambulance Services (NAICS 621910). If you're running wheelchair vans and stretcher cars without paramedics or emergency medical equipment, you belong in 485991, not the ambulance code. Mixing these up on a Medicaid enrollment form can trigger a return-for-correction, which just adds weeks to your file. The Census Bureau's own definition reads: "This industry comprises establishments primarily engaged in providing local, short-distance transportation of passengers by highway systems, using automobiles, vans, or small buses, generally not on a scheduled basis, and providing transportation of passengers with physical disabilities that require an equipped vehicle" (paraphrased from the 2022 NAICS structure, see citation). In plain English: that's your wheelchair van business. Some states and brokers still reference the older 2017 or 2012 NAICS revisions where the code number was the same, 485991, so you generally don't need to worry about which edition year you cite. If a form asks for a NAICS revision year and you're not sure, 2022 is the current standard.

What is NEMT?

NEMT stands for non-emergency medical transportation. It's transportation to and from medical appointments, dialysis, physical therapy, and pharmacy visits for people who don't need an ambulance but can't drive themselves or use regular transit, often because they use a wheelchair or have a condition that limits mobility. Federal Medicaid rules require states to make sure eligible people can get to and from providers. The regulation at 42 CFR 431.53 says states must "ensure necessary transportation for beneficiaries to and from providers" and may do this through direct payment, contracts, or broker arrangements [1]. That's the legal backbone behind every state's NEMT program and the reason broker networks like Modivcare, MTM, Access2Care, and SafeRide exist in the first place. NEMT is not an ambulance ride, and it's not a taxi ride either, at least not in the reimbursement sense. It sits in the middle: a livery-style trip, usually in a wheelchair van, sedan, or stretcher vehicle, coordinated through a state Medicaid transportation broker rather than billed directly like a cab fare. For more on how the broker layer works day to day, see nemt transportation.

Does Medicaid cover ambulance rides?

Yes, Medicaid covers ambulance transportation, but it's billed and regulated separately from NEMT. Ambulance services fall under a different set of Medicaid rules and a different NAICS code (621910, Ambulance Services), and they require licensed EMTs or paramedics and emergency equipment. Medicaid.gov's guidance on NEMT draws the same line: non-emergency medical transportation is for beneficiaries who have no other way to get to covered medical services, while emergency transportation (ambulance) is handled under separate emergency medical services benefit rules [2]. If you're setting up a wheelchair van business, you almost never want to enroll under the ambulance category unless you're actually operating licensed ambulances with clinical staff, which is a different business model, different vehicle certification, and usually a different state licensing agency (often the state health department's EMS office rather than the Medicaid transportation unit). Does Medicare cover medical transportation? Original Medicare Part B covers ambulance transportation when other transportation could endanger your health, and it covers it under strict medical necessity rules, generally not routine non-emergency wheelchair van trips [3]. Some Medicare Advantage plans have started adding limited NEMT-style benefits as a supplemental offering, but that's plan-specific and not a guaranteed benefit under original Medicare. If your business model depends on Medicare NEMT reimbursement, confirm the specific plan's coverage terms directly, because this varies by insurer and by year.

How do you start a medical transportation business?

You start by deciding what kind of trips you'll run (ambulatory wheelchair van, stretcher, or both), then work through five parallel tracks: business formation, vehicle and driver compliance, state Medicaid enrollment, broker credentialing, and insurance. None of these happen in a strict line. Most owner-operators run them at the same time because each one has its own waiting period. Here's the rough order that avoids the most rework: 1. Form your business entity (LLC or corporation) and get your EIN from the IRS. This is also when you'll pick your NAICS code, 485991, on the EIN application (Form SS-4) and later on your state Medicaid provider enrollment form. 2. Get your commercial or for-hire vehicle registration and any state-specific ambulette or medical transport vehicle permit. Requirements vary heavily by state, so confirm with your state Medicaid agency and your state's department of transportation or motor vehicles. 3. Secure commercial auto insurance sized for wheelchair-lift vehicles, plus general liability. Many brokers require specific minimum limits, commonly $1,000,000 combined single limit or higher, though this figure is broker- and state-dependent, so confirm with your broker and state Medicaid agency. 4. Enroll as a Medicaid transportation provider with your state Medicaid agency (this is separate from broker credentialing, and some states require it first). 5. Apply for broker network credentialing with whichever broker or brokers manage NEMT trips in your state or region, such as Modivcare, MTM, Access2Care, or SafeRide. For a state-by-state breakdown of what step 4 actually looks like, see non emergency medical transportation.

How to start a NEMT business, step by step

Starting an NEMT business really comes down to paperwork sequencing, not some mysterious industry secret. The steps below assume you're starting with one wheelchair van, which is the most common entry point. First, register your business entity. Most owner-operators pick an LLC for liability separation, though this is a legal and tax decision worth running past an accountant or attorney, not something to decide from a blog post. Second, get your EIN from the IRS (it's free, directly through irs.gov, and takes minutes if you apply online). Use NAICS 485991 when the application asks for your principal business activity code. Third, title and register your vehicle for commercial or livery use per your state's DMV rules, and get it inspected if your state requires a wheelchair-lift vehicle inspection or ambulette permit. Fourth, apply for a Medicaid provider number through your state Medicaid transportation unit. States administer this differently: some run it centrally, some push it entirely through brokers. Confirm the exact process with your state Medicaid agency's transportation or NEMT unit page. Fifth, apply for broker credentialing. Brokers like Modivcare, MTM, Access2Care, and SafeRide each have their own document checklist: usually driver background checks, vehicle inspection records, insurance certificates, and W-9 or EIN documentation. Confirm current document lists directly with each broker, since they update requirements periodically. Sixth, get driver-side compliance in place: background checks (often including exclusion list screening against the federal List of Excluded Individuals/Entities, or LEIE, maintained by HHS-OIG [4]), defensive driving or passenger assistance training, and drug testing if your state or broker requires it. See [drivers-and-training resources] for the compliance side of this. Sixth-and-a-half: don't skip the OIG exclusion check. Federal Medicaid rules bar payment for services furnished by excluded individuals, and this applies to drivers too, more than billing entities [5].

How to start a non-emergency medical transportation business with one van

One van is genuinely enough to start; you don't need a fleet on day one, and plenty of successful owner-operators began exactly this way. The economics and paperwork are basically the same whether you own one van or ten, just scaled down. With a single vehicle, focus your energy on getting that one van fully compliant rather than spreading thin. That means: correct wheelchair lift or ramp certification per your state's vehicle code, up-to-date commercial insurance naming any required additional insureds (brokers often require this), and a clean vehicle inspection record, because brokers routinely require annual or semi-annual inspections and will suspend you for lapses. One practical note: many state Medicaid programs and brokers cap how many trips they'll route to a single-vehicle operator, or they may prioritize larger fleets in certain regions for logistics reasons. This isn't universal, and it's not something to assume, so ask your target broker directly what volume a one-van operator can realistically expect to be offered, and don't take anyone's word for guaranteed trip volume. No one, including this article, can promise you a specific number of trips or income level from a one-van operation; that depends entirely on your region's broker contract terms and local demand. A one-van operator should also budget time, more than money, for the credentialing wait. Broker credentialing commonly takes anywhere from a few weeks to a couple of months depending on the broker and how complete your initial submission is. Submitting a clean, complete packet the first time is the single biggest lever you control.

What licenses and permits does an NEMT business need?

Requirements vary by state, but most NEMT businesses need some combination of: a business license, a commercial or for-hire vehicle registration, a state-specific ambulette or medical transport permit (not every state has this category), a Medicaid provider enrollment number, and broker credentialing approval. Some states route ambulette/wheelchair van permitting through the state health department, others through the department of motor vehicles, and others through the Medicaid agency itself. There's genuinely no single national answer here, which is why the honest move is to confirm directly with your state Medicaid transportation unit and your state's DMV or health department before you spend money on a vehicle build-out. Driver-level requirements typically include a valid driver's license (commercial license, or CDL, is sometimes required depending on vehicle size and state), a background check, and sometimes a specific passenger assistance or wheelchair securement training certificate. CMS and state Medicaid agencies don't set one federal training standard for NEMT drivers, so this is entirely state and broker-defined territory. Confirm with your broker and state Medicaid agency exactly which certifications they'll accept.

How does state Medicaid enrollment differ from broker credentialing?

State Medicaid enrollmentState Medicaid agencyBusiness license, EIN, NAICS code, vehicle registration, sometimes a state-specific provider agreementA state Medicaid provider number
Broker credentialingPrivate broker (Modivcare, MTM, Access2Care, SafeRide)Insurance certificates, background checks, vehicle inspections, W-9, driver filesAccess to the broker's trip dispatch systemFor deeper detail on this two-layer system, see medical transportation and non emergency medical transportation services.

State Medicaid enrollment and broker credentialing are two separate approvals, and mixing them up is one of the most common early mistakes new owner-operators make. Medicaid provider enrollment is your registration with the state Medicaid agency itself, giving you a provider number the state recognizes. Broker credentialing is your separate application to a private company (Modivcare, MTM, Access2Care, SafeRide, or others) that the state has contracted with to actually coordinate and dispatch NEMT trips. In many states, you need both: the state enrollment establishes you're a legitimate Medicaid provider, and the broker credentialing gets you into the dispatch network that actually sends you trips and pays you. Some states require Medicaid enrollment before broker credentialing will even accept your application; others let the broker handle most of the vetting and only require a lighter state registration. There's no consistent federal rule dictating this sequence, since NEMT program administration is delegated to states under 42 CFR 431.53 [1], and each state designs its own broker contract structure. Here's a comparison of what each layer typically covers: | Layer | Who runs it | What it typically requires | What it gets you |

Which NAICS code should I use on my Medicaid provider enrollment form?

Use 485991 (Special Needs Transportation, Local) for wheelchair van, ambulette, and stretcher car operations that don't involve emergency medical care. This is the code the Census Bureau assigns to exactly this kind of business, and it's the one most state Medicaid enrollment portals expect. If your enrollment form or insurance application only offers broader categories, the next closest options in order of fit are 485999 (All Other Transit and Ground Passenger Transportation) or, if you're also running general non-medical paratransit, 485310 (Taxi Service) adjacent codes, though these are less precise and shouldn't be your first choice if 485991 is available. Do not use 621910 (Ambulance Services) unless you are actually operating licensed ambulances with EMT or paramedic staff and emergency equipment. Using the ambulance code when you're really running a wheelchair van business can cause problems with insurance underwriting (you'd be misrepresenting your risk class) and can flag inconsistencies during Medicaid enrollment review. One more practical point: your NAICS code shows up in more places than just the Medicaid form. It's on your EIN application, often on your state business license, on commercial insurance applications, and sometimes on broker credentialing paperwork too. Keeping it consistent (485991, every time) across all of these documents avoids the kind of mismatch that triggers manual review delays.

What insurance and financial requirements come with the NAICS code?

Your NAICS code itself doesn't set insurance minimums, but underwriters use it to price your risk, and 485991 tells them you're running passenger vehicles with wheelchair equipment for medically vulnerable riders, which is a distinct risk profile from general livery or taxi work. Most commercial auto policies for this NAICS class will ask about lift/ramp equipment, driver training records, and passenger volume. Combined single limit liability requirements commonly requested by brokers range widely, and this genuinely depends on your state and which broker you're credentialing with, so confirm exact figures directly with your broker and your insurance agent rather than assuming a number. General liability and workers' compensation (if you have employees) round out the typical package. Some states also require a specific bond or additional Medicaid provider agreement bond amount; again, this is state-specific, so check your state Medicaid transportation unit's provider manual. Don't shop for insurance using a generic "taxi" or "livery" quote request. Tell your agent the correct NAICS code (485991) and that you're operating wheelchair-accessible vehicles for Medicaid NEMT trips. That gets you an accurate quote instead of a rewrite six months in when the carrier discovers your actual operation type.

Where do I find my state's Medicaid NEMT enrollment page?

Every state Medicaid agency has a transportation unit or vendor management page, though the naming and URL structure differs from state to state. The fastest reliable path is medicaid.gov's own NEMT program page, which explains the federal framework and links out to how states structure their programs [2], combined with a direct search for "[your state] Medicaid non-emergency medical transportation provider enrollment." Because every state runs this differently (some centralize enrollment, some delegate almost entirely to brokers), there's no single national portal that replaces checking your specific state Medicaid transportation unit's site directly. If your state contracts with a broker for the entire NEMT program, that broker's provider recruitment page is often your actual starting point rather than a general state Medicaid portal. For a broader look at broker structures and how the four major national brokers, Modivcare, MTM, Access2Care, and SafeRide, differ in credentialing style, see nemt.

Where the paperwork actually slows people down

Nearly every delay we hear about in this space traces back to one of three things: an inconsistent NAICS code or business name across documents, an incomplete driver file (missing background check results or an expired training certificate), or a vehicle inspection that lapsed between the state application and the broker's own inspection requirement. A $199 one-time State + Broker NEMT Launch Kit exists specifically to keep these documents consistent across your state Medicaid enrollment and broker credentialing packets in one pass, since resubmitting a corrected application usually costs you more time than money. If you're assembling this yourself, the discipline that matters most is simple: use the same business name, EIN, and NAICS code (485991) on every single form, and keep a master folder of current insurance certificates, vehicle inspection reports, and driver files that you can pull from for any broker's specific checklist. This isn't a guarantee of approval from any state or broker, and it isn't legal advice. Every state Medicaid agency and every broker sets its own current requirements, which do change, so always confirm specifics directly before you submit.

Frequently asked questions

What is the NAICS code for non-emergency medical transportation?

485991, titled Special Needs Transportation, Local. The U.S. Census Bureau defines it as local transportation for people with disabilities or the elderly using specially equipped vehicles, explicitly excluding ambulance services, which fall under NAICS 621910 instead.

What is NEMT?

NEMT is non-emergency medical transportation: rides to medical appointments, dialysis, or pharmacy visits for people who can't drive themselves or use regular transit but don't need an ambulance. States must ensure this transportation is available to Medicaid beneficiaries under 42 CFR 431.53.

Does Medicaid cover ambulance rides?

Yes. Medicaid covers ambulance transportation, but it's a separate benefit category from NEMT, with its own NAICS code (621910) and its own licensing rules requiring EMTs or paramedics. NEMT (NAICS 485991) covers non-emergency wheelchair van and stretcher car trips instead.

Does Medicare cover medical transportation?

Medicare Part B covers ambulance transportation when other transport would endanger your health, under medical necessity rules. It generally does not cover routine non-emergency wheelchair van rides under original Medicare. Some Medicare Advantage plans add limited NEMT-style supplemental benefits, but that varies by plan and year.

How do you start a medical transportation business?

Form a business entity and get an EIN using NAICS 485991, register and equip your vehicle to state standards, secure commercial insurance, enroll with your state Medicaid transportation unit, and apply for broker credentialing with the relevant network (Modivcare, MTM, Access2Care, or SafeRide) in your area.

How to start a NEMT business with just one van?

One van is enough to start. Focus on getting that single vehicle fully compliant (lift certification, inspection, insurance), complete state Medicaid enrollment and broker credentialing, and confirm directly with your target broker what trip volume a single-vehicle operator can realistically expect, since this varies by region.

What is non-emergency medical transportation?

Non-emergency medical transportation (NEMT) is scheduled transportation, usually by wheelchair van, stretcher car, or accessible sedan, for people who need help getting to medical appointments but don't require ambulance-level emergency care. It's typically coordinated through state Medicaid transportation brokers.

Do I need a separate license for a wheelchair van business?

Requirements vary by state. Many states require a commercial or for-hire vehicle registration plus a specific ambulette or medical transport permit, sometimes issued by the DMV, sometimes by the health department. Confirm directly with your state Medicaid agency and DMV, since there's no single national standard.

What's the difference between state Medicaid enrollment and broker credentialing?

State Medicaid enrollment registers you as a Medicaid provider with the state itself. Broker credentialing is a separate application to a private company like Modivcare or MTM that actually dispatches trips. Many states require both, and the required order varies by state.

Should I use NAICS 485991 or 621910 for my NEMT business?

Use 485991 (Special Needs Transportation) if you run wheelchair vans or stretcher cars without emergency medical staff or equipment. Use 621910 (Ambulance Services) only if you operate licensed ambulances with EMTs or paramedics. Using the wrong code can cause insurance and enrollment mismatches.

How long does NEMT broker credentialing take?

It commonly takes a few weeks to a couple of months, depending on the broker and how complete your initial submission is. Missing documents, like an expired insurance certificate or an incomplete driver background check, are the most common cause of delay.

Does Medicaid pay for NEMT drivers to be background checked?

Medicaid doesn't directly pay for background checks, but federal rules bar Medicaid payment for services provided by individuals on the HHS-OIG List of Excluded Individuals/Entities. Most states and brokers require driver background and exclusion list screening as part of credentialing.

Can I start an NEMT business without Medicaid enrollment?

You can operate private-pay or contract NEMT trips without Medicaid enrollment, but you can't bill Medicaid for trips unless you're enrolled as a Medicaid provider with your state and, in most states, credentialed with the relevant broker.
