NAICS code for non emergency medical transportation

Last updated 2026-07-25

What is the NAICS code for non emergency medical transportation?

The code is 621910, titled "Ambulance Services" under the North American Industry Classification System. The U.S. Census Bureau's official definition covers establishments "primarily engaged in providing transportation of patients by ground or air, along with medical care," and it specifically includes both emergency and non-emergency ground transportation in this category. That surprises a lot of new owner-operators. You're running wheelchair vans, not ambulances, so the name feels off. But NAICS doesn't have a separate code for wheelchair van or ambulatory NEMT service. The federal classification system lumps all patient ground transport together, whether it's a paramedic-staffed ambulance or a minivan with a ramp and a driver who just finished a defensive driving course. 621910 sits inside NAICS sector 62, Health Care and Social Assistance, under subsector 6219, "Other Ambulatory Health Care Services". That placement matters more than it looks. It's why some state licensing boards route NEMT companies through health department channels instead of pure transportation regulators. It's also why certain business insurance underwriters price you closer to a medical services risk than a taxi risk. You'll see 621910 requested in a few specific places: your IRS EIN application (Form SS-4 asks for a principal business activity code), your state business license or DBA filing, your commercial auto and general liability insurance applications, and sometimes your state Medicaid provider enrollment or NPI (National Provider Identifier) application through NPPES ^[1]. Some brokers ask for it too, mostly for their own internal vendor classification.

What is NEMT?

NEMT stands for non-emergency medical transportation. It's transport to and from medical appointments, dialysis, physical therapy, or pharmacy visits for people who don't need emergency care but can't get there on their own because of a disability, age, or lack of a working vehicle. Federal Medicaid rules require states to make sure eligible beneficiaries can get to and from covered medical services. The regulation at 42 CFR 431.53 says the state Medicaid plan must "ensure necessary transportation for beneficiaries to and from providers" ^[2]. States can run this directly, contract with a transportation broker, or pay providers on a fee-for-service basis, but the obligation itself comes straight from federal law. In practice, NEMT service ranges from ambulatory sedan and rideshare-style trips for people who can walk and get themselves into a car, up to wheelchair van transport for people who use a wheelchair or walker and need a ramp or lift. Some states also cover stretcher van transport for people who must travel lying down but don't need ambulance-level medical monitoring. This is different from ambulance service, which involves emergency or urgent medical need and usually requires EMT or paramedic staffing. NEMT vehicles carry drivers, not medical crews, though many states require CPR/first aid certification and passenger assistance training. For more on how states structure this coverage, see our guide to non emergency medical transportation.

Does Medicaid cover ambulance rides?

Yes, Medicaid covers ambulance rides, but under a different benefit category than NEMT. Ambulance transport is generally covered when it's medically necessary and other transportation would endanger the patient's health, per Medicaid's transportation benefit guidance ^[3]. This is separate from the NEMT benefit that covers routine trips to dialysis or checkups. States set their own medical necessity criteria and reimbursement rates for ambulance transport, and coverage can include both ground and air ambulance depending on the emergency. If you're planning to run ambulance service specifically, you're looking at a different vehicle type, different staffing rules (state EMS certification for EMTs or paramedics), and a different NAICS classification conversation, though it's still 621910 since that code covers ambulance service directly by name. Most new owner-operators buying a single wheelchair van are not getting into ambulance transport. That requires EMS licensure through your state's emergency medical services office, more than a Medicaid provider number. If someone tells you a wheelchair van business and an ambulance business use the same enrollment path, that's wrong. They overlap on the NAICS code but diverge almost everywhere else: vehicle equipment standards, staffing credentials, and the state agency that actually licenses you.

Does Medicare cover medical transportation?

Medicare's coverage of medical transportation is much narrower than Medicaid's. Original Medicare Part B covers emergency ambulance transportation when other transport would endanger your health, and it covers non-emergency ambulance transport only in limited situations, such as when a doctor certifies it's medically necessary because you're bed-confined or need medical services only available via ambulance ^[4]. Medicare generally does not cover routine non-emergency medical transportation like rides to a doctor's office or dialysis in a wheelchair van, per CMS's own coverage guidance ^[4]. That's a real gap for a lot of older adults who are on Medicare but not Medicaid. Some Medicare Advantage plans have started adding limited NEMT-style transportation benefits as a supplemental perk, but this varies plan by plan and isn't guaranteed, so you'd need to confirm coverage details directly with each Medicare Advantage plan you want to contract with. This is exactly why almost every wheelchair van owner-operator entering this business is chasing state Medicaid enrollment and broker credentialing (Modivcare, MTM, Access2Care, SafeRide, or your state's own contracted broker) rather than trying to bill Medicare directly. Medicaid is where the volume and the standing NEMT benefit actually live.

How to start a medical transportation business

Starting a medical transportation business means stacking several approvals in a specific order, and skipping steps costs you time later. Here's the realistic sequence. First, form your business entity (LLC is standard for owner-operators) and get your EIN from the IRS. This is when you'll list 621910 as your principal business activity code on Form SS-4 ^[1]. Second, get your state and local business licenses, which vary by state; some states require a separate passenger transportation or medical transport permit through the state health department or department of transportation. Third, buy or convert your wheelchair van to meet ADA and state accessibility standards, and get your commercial auto and general liability insurance in place. Insurers will ask for your NAICS code here too, and misclassifying yourself as a general taxi or courier service instead of 621910 can create coverage disputes later if a claim happens. Fourth, apply for your state Medicaid provider enrollment. Every state Medicaid agency runs its own provider enrollment process, and many use their broker network (Modivcare, MTM, Access2Care, SafeRide, or a state-specific broker) as the actual credentialing gatekeeper for trip assignment even after you're enrolled with the state. You'll typically need your NPI, your state operating authority, proof of insurance, vehicle inspection records, and driver background check documentation. Fifth, apply for broker credentialing separately. State Medicaid enrollment and broker credentialing are two different processes with two different applications, and you generally need both before you can accept trips. Confirm the exact sequence and requirements with your specific broker and your state Medicaid agency, since these details change often and vary by state. For a fuller breakdown of state-by-state enrollment steps, see medical transportation and nemt transportation.

How to start a NEMT business

Starting a NEMT business specifically (as opposed to general medical transportation, which includes ambulance) narrows your path a bit. You're skipping EMS licensure and ambulance equipment standards, but you're still going through vehicle, insurance, and dual enrollment steps. Your core checklist: business entity and EIN, state passenger transportation authority or NEMT-specific permit (check your state's rules, since some states require a Certificate of Public Convenience and Necessity or similar), ADA-compliant wheelchair van with a lift or ramp meeting your state's inspection standards, commercial auto insurance with limits that meet your state's minimum and your broker's minimum (brokers often require higher limits than the state's bare minimum), driver background checks and any required passenger assistance or CPR training, and finally state Medicaid provider enrollment plus broker credentialing. A one-van operation is a completely realistic way to start, and plenty of owner-operators run exactly this setup. But understand that a single vehicle means you have zero redundancy: if that van is in the shop or fails an inspection, you have no trips going out that day. Some brokers also have minimum fleet or availability expectations buried in their contracts, so read the credentialing agreement before you assume one van is enough for the trip volume they'll try to assign you. This is the exact gap our $199 State + Broker NEMT Launch Kit is built to close: it walks through the state-by-state Medicaid enrollment paperwork and the major broker credentialing packets side by side, so you're not guessing which form goes where.

How do you start a medical transportation business step by step

If you want the condensed version, here's the order most owner-operators actually follow, though your state may insert additional steps. 1. Form your LLC or corporation and get your EIN, listing NAICS 621910 ^[1]. 2. Research your specific state's NEMT licensing requirements through your state Medicaid transportation unit or department of transportation. 3. Buy or convert a wheelchair-accessible van meeting your state's vehicle standards. 4. Secure commercial auto and general liability insurance. 5. Complete required driver training, background checks, and drug testing per your state's rules. 6. Apply for your NPI through NPPES if your state requires one for provider enrollment. 7. Submit your state Medicaid provider enrollment application. 8. Apply separately for broker credentialing with each broker operating in your service area (confirm which brokers hold contracts with your state Medicaid transportation unit). 9. Wait for approval before accepting trips; timelines vary widely by state and broker, so confirm expected processing times directly rather than assuming a fixed number. Every one of these steps has a state-specific wrinkle. Some states run NEMT through a single statewide broker; others use regional brokers or a mixed fee-for-service and broker model. There's no substitute for pulling your own state Medicaid transportation unit's page and reading the actual requirements, because generic national guides (this one included) can only get you to "here's the shape of the process," not the exact form numbers.

What NAICS code should I use on insurance and licensing forms?

Use 621910 consistently across every form: your EIN application, your business license, your commercial auto policy, your general liability policy, and any state or broker paperwork that asks for it. Consistency matters because your NAICS code follows you into audits, workers' comp classification, and sometimes broker vendor files. A common mistake: owner-operators list themselves under a general "taxi and limousine service" code (485310 or similar passenger transportation codes) because that's what a generic business registration wizard suggests. That's the wrong code for NEMT specifically, since the Census Bureau's own classification system places all patient transport, emergency and non-emergency, under 621910. If your insurance application lists you under a taxi code but you're transporting Medicaid patients under a medical transportation contract, an insurer could argue your policy doesn't match your actual operation if a claim ever gets disputed. That's not a guaranteed outcome, it depends on your policy language and state law, but it's a completely avoidable risk. Just use the right code from day one. Some states also maintain their own classification codes separate from NAICS for provider enrollment purposes (sometimes tied to their Medicaid Management Information System or MMIS provider type tables). Don't assume your NAICS code substitutes for whatever state-specific provider type code your Medicaid agency requires; confirm both with your state Medicaid agency directly.

How does NAICS 621910 affect Medicaid provider enrollment?

NAICS 621910 itself doesn't grant or block Medicaid enrollment. It's a classification code, not a credentialing credential. Your actual enrollment depends on your state Medicaid agency's provider enrollment application, your operating authority, insurance, vehicle inspections, and driver qualifications. That said, some state Medicaid provider enrollment portals and some broker credentialing systems ask for your NAICS code as a data field, usually to confirm you're registered as a transportation or health services entity rather than something unrelated. If your business documents (EIN, state registration) list a mismatched code, like a general logistics or courier code, it can trigger extra questions or delays during review. Keeping 621910 consistent across your formation documents removes one small friction point from an already document-heavy application. The real gatekeeping happens elsewhere: your state's specific NEMT provider type designation in its Medicaid Management Information System, your broker's separate vendor credentialing packet, and your vehicle and driver compliance documentation. Confirm the exact provider enrollment requirements and any NAICS or classification fields directly with your state Medicaid agency, since portal designs and required fields vary by state and change over time. For state-specific breakdowns of enrollment paths, our non emergency medical transportation services page walks through how different states structure this.

What's the difference between NEMT and emergency medical transport?

NEMT covers scheduled, non-urgent trips for people who need transportation assistance but not emergency medical care. Emergency medical transport, meaning ambulance service, covers situations where the patient's condition requires medical monitoring or intervention during transit, or where any delay or wrong mode of transport would endanger their health ^[3]. The practical differences show up in vehicle type, staffing, and regulation. NEMT wheelchair vans need ramps or lifts, tie-downs, and drivers trained in passenger assistance, but no medical staff on board in most cases. Emergency medical transport vehicles require EMT or paramedic staffing, medical equipment, and state EMS licensure through a completely different regulatory body than most NEMT permitting. Both fall under NAICS 621910, which is genuinely confusing if you're trying to research your business type online and keep landing on ambulance-focused results. If you're specifically researching the emergency side, our emergency medical transport guide covers that separately from the NEMT path most wheelchair van owner-operators are actually pursuing.

How long does it take to get Medicaid and broker approval?

There's no single national timeline, and anyone who gives you a firm number without knowing your state is guessing. State Medicaid provider enrollment processing times vary by state, by application completeness, and by current backlog at your state's Medicaid agency or its fiscal agent. Broker credentialing (Modivcare, MTM, Access2Care, SafeRide, or your state's specific contracted broker) runs on a separate timeline from state Medicaid enrollment, and brokers typically require you to have your state provider enrollment substantially done, or at least your NPI and operating authority in hand, before they'll process your credentialing packet. Some owner-operators report the combined process taking anywhere from a few weeks to several months, but that range reflects real variation in state backlogs and application completeness, not a guarantee of any specific timeframe for your situation. The single biggest lever you control is submitting a complete, accurate application the first time. Missing insurance documentation, an expired background check, or a mismatched NAICS code across your formation documents are common reasons applications bounce back for corrections, and each round trip adds real weeks to your timeline. Confirm current processing expectations directly with your state Medicaid transportation unit and each broker you're applying to, since these numbers shift with staffing and volume.

Frequently asked questions

What is the NAICS code for non emergency medical transportation?

The NAICS code is 621910, titled "Ambulance Services" by the U.S. Census Bureau. It covers all ground and air patient transportation, both emergency and non-emergency, so wheelchair van and ambulatory NEMT businesses use the same code as ambulance companies. There's no separate NAICS code specifically for wheelchair van or ambulatory transport service.

What is NEMT?

NEMT stands for non-emergency medical transportation. It's transport to medical appointments, dialysis, therapy, or pharmacy visits for Medicaid beneficiaries and other patients who can't drive themselves due to disability, age, or lack of transportation, but who don't need emergency medical care during transit.

Does Medicaid cover ambulance rides?

Yes. Medicaid covers ambulance transportation when it's medically necessary, meaning other transportation would endanger the patient's health. This is a separate benefit category from routine NEMT coverage, with its own medical necessity rules set by each state Medicaid agency.

Does Medicare cover medical transportation?

Medicare Part B covers emergency ambulance transport and limited non-emergency ambulance transport when a doctor certifies medical necessity. It generally does not cover routine non-emergency rides like trips to a doctor's office in a wheelchair van, though some Medicare Advantage plans offer limited supplemental transportation benefits.

How do I start a medical transportation business?

Form your LLC, get an EIN with NAICS code 621910, secure state transportation licensing, buy an ADA-compliant vehicle, get commercial insurance, complete driver background checks and training, then apply for state Medicaid provider enrollment and separate broker credentialing before accepting trips.

How do I start a NEMT business with just one van?

One van is a workable starting point. You still need the full checklist: entity formation, state licensing, ADA-compliant vehicle, commercial insurance, driver qualifications, and both state Medicaid enrollment and broker credentialing. Understand that one vehicle means no backup if it's out of service, and some brokers expect minimum availability you should confirm before signing.

What's the difference between NEMT and an ambulance ride?

NEMT is for stable patients who need help getting to appointments but not medical monitoring during the trip. Ambulance transport is for situations requiring medical care or monitoring en route, staffed by EMTs or paramedics. Both share NAICS code 621910, but require different licensing, vehicles, and staffing.

Do I need a special business license for NEMT beyond the NAICS code?

Yes. NAICS 621910 is a classification code, not a license. You'll separately need state or local transportation authority, possibly a Certificate of Public Convenience and Necessity, vehicle permits, and state Medicaid provider enrollment. Requirements vary by state, so confirm with your state Medicaid transportation unit.

How much does it cost to start a NEMT business?

Costs vary enormously based on whether you buy new or used wheelchair vans, your state's licensing fees, insurance premiums, and conversion costs if retrofitting a vehicle. There's no reliable single national figure; get quotes for your specific state and vehicle choice before budgeting.

Is NEMT the same as medical transportation?

NEMT is one category within the broader medical transportation field. Medical transportation also includes emergency ambulance service, which requires different licensing (EMS certification) and equipment than NEMT wheelchair van or ambulatory service.

What insurance do I need for a NEMT wheelchair van business?

You'll typically need commercial auto insurance with limits meeting both your state's minimum and your broker's requirement (brokers often require higher limits), plus general liability coverage. Requirements vary by state and broker, so confirm specific minimums directly rather than assuming standard personal auto coverage applies.

Can I bill Medicare instead of Medicaid for NEMT trips?

Generally no. Medicare doesn't cover routine non-emergency medical transportation the way Medicaid does. Some Medicare Advantage plans offer limited transportation benefits as a supplemental perk, but you'd need to contract with each plan separately and confirm coverage terms, since this isn't a standard Medicare benefit.

Do state Medicaid agencies and brokers require the same NAICS code?

Most ask for 621910 if they ask at all, but some states use their own separate provider type codes within their Medicaid Management Information System that aren't the same as NAICS codes. Confirm both your NAICS code and any state-specific provider type classification directly with your state Medicaid agency.
