How to bill for non-emergency medical transportation (NEMT)

Last updated 2026-07-25

What is non-emergency medical transportation (NEMT)?

NEMT is transportation to and from medical appointments for people who don't need an ambulance but can't drive themselves or use public transit, usually because of a wheelchair, a disability, a cognitive issue, or just not having a car. Think dialysis three times a week, physical therapy, dental visits, or a ride home after an outpatient procedure. It is not a 911 response and it is not staffed with paramedics. Federal Medicaid rules require states to make sure eligible people can get to and from providers, and NEMT is the mechanism most states use to meet that obligation. The regulation lives at 42 CFR 431.53, which says states must "ensure necessary transportation for beneficiaries to and from providers" ^[1]. States can run NEMT themselves, contract with a single statewide broker, or split it by region. That structural choice is exactly why billing looks so different from state to state. If you're still deciding whether this business fits your life at all, start with the basics on non emergency medical transportation before you get into billing codes.

How do you start a medical transportation business?

You need four things lined up before billing ever becomes relevant: a legal business entity, a vehicle that meets your state's ADA and wheelchair-lift standards, commercial insurance, and Medicaid provider enrollment (plus broker credentialing in broker states). Skip any one of these and you can't submit a clean claim, no matter how good your paperwork is. Most new operators form an LLC, get a federal EIN, then apply for a state business license and any local for-hire vehicle permit their county or city requires. Next comes the vehicle: a used wheelchair van with a lift or ramp typically runs somewhere in the $15,000 to $35,000 range depending on age and mileage, though prices swing a lot regionally and by conversion type. After that you need commercial auto insurance (personal auto policies exclude for-hire transport), then Medicaid enrollment through your state's Medicaid Management Information System (MMIS) portal, and finally broker credentialing if your state uses one. The order matters. Enrollment and credentialing both ask for proof of insurance and vehicle inspection documents, so lining those up first saves you from bouncing an application back and forth. For a step-by-step breakdown of the nemt enrollment sequence, that's a separate deep piece worth reading before you touch a claim form.

How to start a NEMT business with one van

A single-van operation is completely viable to launch, but you should treat billing as a full-time administrative job on top of driving, not an afterthought. With one vehicle you're both the driver and the back-office person, so build billing habits into your daily routine from trip one. Concretely: get your Medicaid provider number and broker ID before you take a single ride, buy or build a simple trip log (date, pickup/drop-off address, mileage, loaded miles vs. deadhead, member ID, authorization or trip confirmation number), and decide up front whether you'll bill weekly or daily. Most brokers pay on a set cycle regardless of when you submit, so batching claims weekly is usually enough and saves you time versus doing it every single day. One-van owners often underestimate how much documentation a single denied or under-mileage claim can eat into a week. Confirm with your broker and state Medicaid agency exactly what counts as a completed trip (some require a rider signature or an electronic visit verification (EVV) check-in/check-out) before you're 100 trips deep and find out your logs are missing a required field.

How do NEMT brokers pay claims (Modivcare, MTM, Access2Care, SafeRide)?

In most broker states, you don't file a traditional Medicaid claim at all. You get a trip assignment through the broker's dispatch app or portal, complete the trip, and submit a trip confirmation (sometimes with a rider signature or EVV data), and the broker pays you on its own schedule, often weekly or biweekly, at its own contracted rate. Each broker runs its own provider portal and its own rate structure, and none of that is standardized nationally. Modivcare, MTM, Access2Care, and SafeRide each have separate credentialing processes, separate rate sheets by service level (ambulatory sedan, wheelchair van, stretcher), and separate documentation requirements for mileage and loaded/unloaded miles. What one broker accepts as proof of trip completion, another might reject outright. This is the single biggest trap for new owner-operators: assuming billing works the same everywhere. It doesn't. Confirm with your specific broker contract exactly how trips are confirmed, how disputes get filed, and how fast payment actually posts, because "14 days" on paper can mean 30 days in practice once you factor in review holds. If your state runs multiple regions with different brokers, or is transitioning from one broker to another (which has happened repeatedly across states over the past decade), your billing process can change on short notice even if nothing about your service changes. Check with your state Medicaid transportation unit for the current broker assignment before you assume last year's process still applies.

How do you bill Medicaid directly in fee-for-service NEMT states?

Broker-managed (most states)	Broker portal (Modivcare, MTM, etc.)	Trip confirmation number, EVV, no HCPCS needed	Often 14 to 30 days per contract
State fee-for-service	State MMIS directly	CMS-1500 / 837P, HCPCS (A0080-A0130, T2003, T2005)	Varies by state, often 30 days
County/transit-run	County program office	Often locally defined trip logs	Varies widely

A minority of states still pay NEMT through direct fee-for-service Medicaid billing rather than a broker, and a few counties or transit districts run it as a public program. In those states you typically submit a CMS-1500 claim form (or its electronic 837P equivalent) using HCPCS transportation codes, your NPI number, and the Medicaid member ID, directly to the state's MMIS. Common HCPCS codes used in ground medical transport billing include A0080 and A0090 (non-emergency transport by volunteer or individual, with and without mileage), A0100 (non-emergency taxi), A0110 (non-emergency bus), A0120 (non-emergency mini-bus/mountain area/multi-passenger van), A0130 (wheelchair van), and mileage codes like A0080/A0090's mileage components; some states also use T2003 (non-emergency transport, encounter/trip) or T2005 (non-emergency transport, stretcher van) ^[2]. Which of these your state actually recognizes, and at what reimbursement rate, varies enormously, so confirm the exact code set and rate table with your state Medicaid transportation unit before billing anything. The HHS Office of Inspector General has separately reviewed state NEMT programs and found documentation gaps a recurring theme. Its review of Kentucky's Medicaid NEMT brokerage program found that the state "did not always ensure that NEMT broker network drivers met State requirements" and that some trip records were incomplete ^[3]. That's a strong signal to get your codes and documentation practices verified in writing by your state agency rather than guessing from a code list you found online, including this one. | Billing model | Who you bill | Typical codes/process | Payment timing |

Does Medicaid cover ambulance rides?

Yes, but ambulance transport and NEMT are billed completely differently and covered under different rules. Medicaid covers emergency ambulance transport when a beneficiary's condition requires it, and many states also cover non-emergency ambulance transport (for example, a non-ambulatory dialysis patient who needs stretcher-level medical monitoring) when a physician certifies medical necessity ^[1]. Ambulance claims use their own HCPCS code set (A0426, A0428, A0429, and others depending on ground/air and emergency/non-emergency status) and are billed by the ambulance provider, not the NEMT company. If your wheelchair van business gets asked to transport someone who actually needs ambulance-level medical monitoring, that's outside your scope of service and should be redirected, both for compliance and for liability reasons. The practical takeaway for NEMT owner-operators: don't confuse "ambulance coverage" questions from riders or family members with your own billing process. You're billing for transport, not medical care, and Medicaid treats those as separate benefit categories with separate provider types.

Does Medicare cover medical transportation?

Medicare's NEMT coverage is much narrower than Medicaid's. Original Medicare Part B covers ambulance services when other transportation "could endanger your health" ^[4], but it generally does not cover routine non-emergency rides to a doctor's office or dialysis in a wheelchair van the way Medicaid does. Some Medicare Advantage (Part C) plans offer NEMT as a supplemental benefit under CMS rules that let plans cover items and services that are "not otherwise covered by Medicare" if they meet CMS's primarily health-related definition, a flexibility CMS finalized in its 2019 Medicare Advantage policy rulemaking ^[5]. Coverage still varies plan by plan and is not guaranteed under standard Medicare. If you're building a business plan around Medicare-funded rides, don't assume coverage; you need to confirm with each specific Medicare Advantage plan whether they offer a transportation benefit and how their billing/authorization process works, because it is nothing like Medicaid's broker system. Most owner-operators entering this business will find Medicaid, not Medicare, is the real volume driver, which is part of why state Medicaid enrollment sits at the center of everything discussed on this site.

What documentation do you need for a clean NEMT claim?

Every broker and state wants the same core facts even if the form looks different: who rode, where they went, when, how far, and proof the trip actually happened. Missing any one of these is the number one reason claims bounce back for correction or get denied outright. At minimum, keep a trip log with the rider's Medicaid ID or member number, pickup and drop-off addresses, date and time of pickup and drop-off, odometer readings or GPS-logged mileage, the authorization or trip confirmation number issued by the broker, and a signature (rider, facility staff, or EVV check-in/out depending on your state's rules). Many states now require electronic visit verification for NEMT trips, following the 21st Century Cures Act's EVV mandate, codified at 42 U.S.C. 1396b(l), which originally targeted personal care and home health services but has been extended by some states to NEMT as well ^[6]. Confirm with your state Medicaid agency whether EVV applies to your trips. Keep copies of everything for at least the retention period your provider agreement specifies, commonly five to seven years for Medicaid records, though you should confirm the exact figure in your state's provider manual since it varies.

Why do NEMT claims get denied and how do you fix it?

The most common denial reasons are mismatched or expired authorization numbers, mileage that doesn't match the broker's own mapping system, missing signatures, billing for a higher level of service than was authorized (billing wheelchair-van rate for what was authorized as ambulatory), and late submission past the broker's filing deadline. A practical fix for most of these: build your trip log directly from the broker's own trip assignment screen instead of retyping addresses from memory, since even small address formatting differences can trigger a mileage mismatch. If a broker's system authorizes a trip as "ambulatory" but the rider actually needs the wheelchair lift, call before the trip to get the authorization corrected rather than billing at the higher rate and hoping it goes through. That mismatch is one of the fastest ways to get flagged for a documentation audit. When a claim is denied, every broker and state has an appeal or dispute window (commonly 30 to 60 days, but confirm the exact number with your specific broker contract or state provider manual). File the appeal in writing with your trip log attached rather than calling and hoping someone fixes it verbally; verbal resolutions rarely show up in the system record if the claim gets audited again later.

How to start a NEMT business (state Medicaid enrollment and broker credentialing steps)

Enrollment and credentialing are two different processes and you usually need both. State Medicaid provider enrollment gets you a state provider number and lets you bill the state (directly in fee-for-service states, or as a prerequisite in most broker states). Broker credentialing is a separate application to Modivcare, MTM, Access2Care, SafeRide, or whichever broker your state contracts with, and it's what actually gets you trip assignments. Typical requirements across both processes include: business entity documents, EIN, commercial auto insurance meeting state-specified minimum limits, vehicle inspection certificates (often annual), driver background checks and drug testing records, driver training certificates (defensive driving, passenger assistance, sometimes CPR/First Aid), and a completed provider enrollment application through your state's MMIS portal. Because requirements and forms genuinely differ by state and by broker, and because brokers do change their credentialing packets, this is the point where a lot of new owner-operators either lose weeks to back-and-forth paperwork or pay a consultant a few thousand dollars to hold their hand through it. If you'd rather have every state and broker form pulled together in one place before you start applying, that's exactly what RideCredential's $199 one-time State + Broker NEMT Launch Kit is built for. It doesn't replace your state's actual requirements or guarantee approval, but it saves you from hunting down forty different PDFs on forty different agency websites. For the state-by-state variation in what "provider enrollment" actually requires, see medical transportation and non emergency medical transportation services for the broader landscape before you file anything.

How long does NEMT payment actually take?

There's no single national answer, but a reasonable range to expect is 14 to 30 days from clean claim submission for most broker-paid trips, and up to 30 to 45 days for some state fee-for-service claims, assuming no documentation errors. Brokers typically run on a fixed payment cycle (weekly or biweekly) regardless of when during that cycle you submitted, so a trip completed the day after a payment run closes can sit almost a full extra cycle before it's paid. The honest caveat here: publicly available, state-by-state payment-timing data for NEMT specifically is thin. Most of what's documented publicly covers state prompt-pay laws for Medicaid claims broadly, not NEMT trip payments specifically, and broker contracts aren't public documents. Your best source of truth is your own broker's provider manual and your own state Medicaid agency's provider services contact, not a generic number from an article. Budget for a cash-flow gap in your first two to three months of operation. New owner-operators frequently underestimate how long that first payment cycle takes relative to their fuel, insurance, and vehicle payments, and it's one of the more common reasons a promising single-van operation runs into trouble early, not because the business model is bad but because the timing math wasn't planned for.

NEMT billing checklist for new owner-operators

Before your first trip, confirm five things in writing with your broker and state Medicaid agency: your provider/broker ID number, the exact trip confirmation or EVV process required, the HCPCS codes or trip codes that apply if you're in a fee-for-service state, your payment cycle and filing deadline, and your appeal/dispute window for denied claims. After every trip, log the same six fields every time: member ID, date/time, addresses, mileage, authorization number, and signature or EVV confirmation. Consistency here matters more than the specific software or paper form you use. Every week, reconcile what you submitted against what actually got paid, and follow up on anything unpaid past the stated cycle before it becomes a stack of six denials you have to untangle at once. Billing discipline, more than almost anything else in this business, is what separates operators who get paid reliably from operators who spend their evenings on hold with a broker's provider line. Once your billing rhythm is solid, the next thing worth reading is how nemt transportation fits into broader state Medicaid transportation networks, and how to tell the difference between routine NEMT and emergency medical transport so you never accidentally take on a trip outside your authorization or your vehicle's capability.

Frequently asked questions

What is non-emergency medical transportation (NEMT)?

NEMT is transportation to medical appointments for Medicaid (and sometimes Medicare Advantage) beneficiaries who don't need an ambulance but can't get to care on their own, often because of a wheelchair or disability. States must ensure this transportation exists under 42 CFR 431.53, and most states run it through a contracted broker like Modivcare, MTM, Access2Care, or SafeRide.

How to start a NEMT business?

Form a legal business entity, buy or lease a vehicle meeting your state's wheelchair-accessibility standards, get commercial auto insurance, complete state Medicaid provider enrollment through your MMIS, and complete broker credentialing if your state uses one. Order matters: insurance and vehicle documents are required inputs for both enrollment and credentialing applications.

How do you start a medical transportation business with just one van?

One van is enough to start, but plan to handle billing, dispatch, and driving all yourself. Get provider enrollment and broker credentialing done before your first trip, build a simple trip log with mileage and authorization numbers, and budget for a 14- to 45-day cash-flow gap before your first payment cycle clears.

Does Medicaid cover ambulance rides?

Yes. Medicaid covers emergency ambulance transport and, in many states, non-emergency ambulance transport when a physician certifies medical necessity for stretcher-level monitoring. Ambulance billing uses separate HCPCS codes (A0426, A0428, A0429, etc.) and is billed by ambulance providers, not by NEMT wheelchair-van companies.

Does Medicare cover medical transportation?

Original Medicare Part B mainly covers ambulance transport when other transportation would endanger the patient's health; it generally does not cover routine non-emergency rides. Some Medicare Advantage plans offer NEMT as a supplemental benefit, but coverage varies by plan, so confirm directly with the specific plan before assuming it applies.

What HCPCS codes are used for NEMT billing?

Common codes include A0080 and A0090 (non-emergency transport by individual/volunteer), A0100 (taxi), A0110 (bus), A0120 (mini-bus/van), A0130 (wheelchair van), and T2003 or T2005 in some states for trip- or stretcher-based billing. Not every state recognizes every code, so confirm the exact set with your state Medicaid transportation unit.

How do NEMT brokers like Modivcare or MTM actually pay providers?

Most brokers use a portal where you accept trip assignments, complete the ride, and submit a trip confirmation (sometimes with electronic visit verification or a signature). Payment runs on the broker's own cycle, often weekly or biweekly, at rates set in your broker contract, not through a traditional Medicaid claim form.

How long does it take to get paid for a NEMT trip?

A reasonable estimate is 14 to 30 days for broker-paid trips and up to 30 to 45 days for state fee-for-service claims, assuming clean documentation. Exact timing depends on your broker's payment cycle and your state's claims processing rules, so confirm the specific figure in your provider contract or manual.

Why was my NEMT claim denied?

Common reasons include expired or mismatched authorization numbers, mileage disputes, missing signatures or EVV data, billing a higher service level than authorized, and missed filing deadlines. Most brokers and states allow a written appeal within 30 to 60 days; always attach your original trip log to the appeal.

What documentation do I need to bill for an NEMT trip?

Keep the rider's Medicaid ID, pickup/drop-off addresses and times, mileage, the broker's trip authorization or confirmation number, and a signature or EVV check-in/out. Retain records for the period your provider agreement specifies, commonly five to seven years, though you should confirm the exact figure with your state.

Do I need broker credentialing and state Medicaid enrollment, or just one?

In most states you need both. State Medicaid enrollment gives you a provider number and satisfies program requirements; broker credentialing with Modivcare, MTM, Access2Care, or SafeRide is what actually gets you trip assignments. Confirm with your state Medicaid transportation unit whether your state uses a broker at all, since a few still run NEMT directly.

How much does it cost to start a wheelchair van NEMT business?

Costs vary widely, but a used wheelchair-accessible van typically runs $15,000 to $35,000, plus commercial insurance, licensing fees, and driver training costs. This article and its citations don't project revenue or trip volume; budget conservatively and confirm insurance minimums with your state before buying a vehicle.
