How to bill Medicaid for NEMT and get paid as a transportation provider

How do transportation providers bill Medicaid for NEMT?

You bill Medicaid for NEMT by sending each completed trip to the entity that authorized it: a transportation broker, a managed care plan, or the state’s own fee-for-service claims system. Which one applies depends on the state and on the member’s coverage, and a provider in one state can face all three in the same week.

The benefit itself is federal. Every state Medicaid plan must specify that the agency will ensure necessary transportation for beneficiaries to and from providers, and describe the methods it will use². Transportation is covered as medical assistance, including related travel expenses such as meals, lodging and an attendant where the agency finds them necessary, and a state may set up a brokerage program to deliver it¹. The CMS provider booklet describes three delivery systems: a transportation broker, transportation as a managed care benefit, and contracted vendors paid directly by the state³.

One rule sits above all three. The transportation provider must have a contract with the appropriate entity before any trip is furnished; without it, Medicaid payment is not available even when every other requirement is met³. The contract, the enrollment and the broker credentialing come first, and the billing follows.

What is the difference between broker billing and fee-for-service billing?

Under a broker, the trip is assigned to you, the broker’s rate sheet sets the price, and you submit through the broker’s platform; under fee-for-service, you bill the state’s claims system with transport codes, modifiers and the state’s authorization number, and the state fee schedule sets the price.

How brokers are set up

The federal rule shapes how a broker behaves toward you. A state may contract with a broker selected by competitive bid on experience, performance, references, resources, qualifications and costs; the broker must have oversight procedures for beneficiary access and complaints, must ensure transportation is timely and that transport personnel are licensed, qualified, competent and courteous, and is subject to regular state audit¹. The same rule bars a transportation provider from offering any payment, kickback, rebate, cash, gift or in-kind service to a broker to influence referrals or subcontracting¹.

Two national brokers describe their networks in public. MTM Health says it operates in all 50 states and the District of Columbia, serves 24 million members and arranges 35 million trips a year, with trips scheduled and tracked through its MTM Link app and portal¹². Modivcare says it works with more than 6,500 subcontracted transportation providers and 26,000 vehicles for about 35 million paid trips a year, and offers providers its WellRyde dispatch platform at no or reduced cost, with GPS systems that automate information for claims¹¹. Modivcare also verifies vehicles against contract standards through field visits¹¹. Each broker’s own page on this site sets out its portal, documentation and common rejections.

How fee-for-service claims look

New York is a clear example of the fee-for-service path. Transportation providers submit electronic claims on the HIPAA 837P or paper claims on the state’s own Form A, and need an electronic transmitter identification number and a certification statement, renewed annually, before they can submit at all⁴. Each non-emergency claim carries the 11-digit prior authorization number from the transportation roster, and where trips fall under different prior approvals each approval needs its own claim⁴. A claim without the ordering provider’s NPI is rejected⁴.

Managed care in the middle

A managed care plan may arrange its own transportation or hand it to a vendor, and the member’s plan decides which path you follow. Iowa, for example, has MTM as its broker for fee-for-service members while members in managed care plans contact their plan for rides⁷. The practical consequence: eligibility on the day of the trip tells you who pays, and a trip billed to the wrong entity is a rejection, not a payment.

What must every trip record show?

At a minimum, every state requires the member’s name and Medicaid identifier, the pickup and drop-off locations, the date and time the service was furnished, and the number of miles traveled with the member in the vehicle³. Some states and brokers also require the member’s signature on the transport record at the end of the trip³. Everything you bill has to trace back to that record, and the booklet’s own line is the right one to remember: if a service is not documented, there is no point in submitting a claim for it³.

Loaded mileage is the unit that gets providers into trouble. A typical state definition is the time the member is actually in the vehicle; if the driver arrives and the member does not show, the trip generally cannot be billed, and claiming loaded miles for a no-show is billing for a service not rendered³. Trips to non-medical destinations are not covered and must not be billed³. The CMS booklet says that in most states providers cannot receive extra payment for wait time, which may already be counted in the rate, so check the state or broker rule before putting it on a claim³.

Some states want the vehicle and the driver on the claim itself. New York’s ambulette and taxi or livery claims carry the license plate number of the vehicle and the driver’s license number of the driver, alongside the ordering provider’s NPI⁴. Brokers capture the same facts through their apps: GPS points at pickup and drop-off, timestamps, and a signature or attestation on the device.

Management has a job here too. Even where the member’s signature is required, the booklet puts responsibility on the owner or a designee to verify that documented services were furnished, by making random calls to members and to the appointment locations³. Keep a note of the calls; they are the evidence that your records are real.

Which codes and modifiers go on an NEMT claim?

Where you bill a state or a plan on a claim rather than through a broker’s trip record, the lines are HCPCS Level II transport codes with a two-letter origin and destination modifier on each, and the full list with plain-language explanations is on the NEMT billing codes page. This guide does not repeat them. The pattern is one line for the trip, a second line for mileage where the program pays it with the miles as units, and the modifier on both.

The state fee schedule is the authority on which codes it accepts and at what rate. New York publishes its transportation fee schedule and billing guidelines on its transportation manual page¹⁵. On a New York claim, non-emergency transportation uses place of service 99; where a trip was run more than once on the same date, the number of round trips goes in the times-performed field; mileage goes in the miles field; and the charge for a round trip is the one-way fee multiplied by two⁴.

A broker that pays from the trip record does not need a coded claim. It pays against the rate sheet, and the level of service on the assignment (ambulatory, wheelchair, stretcher) is what the code would have said. Confirm the level at dispatch, not after the short payment.

How do you submit the claim?

There are three submission paths, and a provider can need more than one: the broker’s platform for assigned trips, an 837P to the state or plan for fee-for-service trips, and paper only where nothing else is accepted.

Broker platforms are the broker’s own. Modivcare offers WellRyde, with online claims submission¹¹; MTM’s service providers log in to MTM Link to access their trips¹³. Each platform has its own rejection codes and its own window for submitting a completed trip, and that window is in your contract, not on a public page.

Fee-for-service claims go to the state’s Medicaid management information system. In New York that is eMedNY, by 837P or on the state’s Form A, with the authorization number on each claim and a separate claim per approval⁴. The CMS booklet notes that providers normally bill state transportation services on the CMS-1500, and the form’s instructions warn that a claim containing false, incomplete or misleading information can be a criminal act³.

Timely filing is set by each program. New York requires claims within 90 days of the date of service unless acceptable circumstances for the delay are documented⁴. Other states and every broker set their own limits; the timely filing limits table lists the ones verified so far. Submitting completed trips daily keeps them well inside the window.

How does trip reconciliation work?

Reconciliation is matching every completed trip to a submission, and every submission to a remittance line, every week, so that a trip can only end in one of four states: paid as billed, paid short, rejected, or never submitted. The fourth is the expensive one, because nobody sends a denial for a trip they never received.

Start from dispatch, not from the claims system. The list of trips marked complete is the control total. Against it, mark each trip with its submission date and reference, then with the remittance line that paid or rejected it. A fee-for-service remittance shows each claim’s status as paid, denied or pended, the edits that caused a denial or pend, and financial items such as recoupments and negative balances⁴. Broker payment reports show the same by trip, against the broker’s calculated mileage and rate.

Corrections have their own mechanics. In New York an adjustment corrects a paid claim and a void cancels it, each referencing the original 16-digit transaction control number⁴. Where a member has other coverage, Medicaid is the payer of last resort and the other carrier is billed first⁴. Where Medicare covers an emergency transport, the claim crosses over rather than being billed to Medicaid separately⁴.

Why do NEMT claims get rejected or short-paid?

The NEMT rejections and short payments below trace back to the trip record rather than the code: the trip was not assigned, the record is missing an element, the level of service does not match, the miles disagree, or the same trip was sent twice. The fixes are operational, which is why the biller has to be in the dispatch data and not only in the portal.

• No assignment or no authorization. The trip was run without a broker assignment, or the claim is missing the state’s authorization number. A fee-for-service denial for this reads as CO-197. Raise unassigned trips with the broker before the trip where you can; where you cannot, document in full and expect a dispute.
• Missing information on the record or the claim. No signature where one is required, no driver or vehicle where the state wants it, or no ordering provider NPI, which New York rejects outright⁴. On a coded claim this surfaces as CO-16. Fix the capture at the point of the trip.
• Level of service mismatch. A wheelchair trip assigned as ambulatory, or the reverse. Confirm at dispatch and correct with the broker before the vehicle moves.
• Mileage disputes. The broker’s calculated miles differ from the odometer. Dispute trip by trip with GPS points and the route; accept the broker’s figure only when the record cannot support yours.
• Duplicates and overlaps. Two submissions for one trip, or one driver in two places at once. Reconciliation catches these before they leave; a duplicate that reaches the payer is a recoupment later.
• Late submission. The trip missed the broker’s or state’s window. Submitting daily keeps trips inside the window; appeals for late filing need documented cause⁴.
• No-shows and non-medical trips. Billed by mistake from a dispatch record that was never corrected. Both are unbillable³, and the booklet calls claiming loaded miles for a no-show a common form of NEMT fraud³.
• Excluded driver. No federal health care program payment may be made for trips an excluded driver or contractor furnished, and those claims can be recouped as overpayments; the CMS booklet tells providers to screen staff and contractors before hiring and repeat the check monthly³.

How do the rules differ by state?

Every state meets the federal transportation assurance in its own way, so the first question in any new state is who holds the contract: one statewide broker, regional brokers, the managed care plans, or the state itself. The CMS booklet makes the point directly: every state’s program is different, waiver programs add their own rules, and the provider is responsible for knowing the rules of each state and each program it serves³.

The lesson from the table is not the detail of any one state. It is that the submission path, the authorization and the filing window all change at the state line, and a provider operating in two states runs two billing processes.

How do you get set up to bill in the first place?

Before the first trip you need a Medicaid enrollment with the state, a credential with each broker or plan you will carry members for, and a monthly exclusion check in place. The federal rule requires the state Medicaid agency to screen every enrolled provider and to revalidate every provider at least every 5 years¹⁴, so enrollment is a recurring task rather than a one-time form.

New York shows what the broker side can look like. A provider applies to Medical Answering Services, whose provider relations team reviews the application for a letter of support; the provider then applies to the state with that letter, waits for an enrollment determination that can take 90 days or longer, and finally contracts with MAS on its network requirements⁵. Modivcare verifies vehicles through field visits and gives providers access to NEMT training programs for Medicaid and Medicare members¹¹. MTM says it contracts commercial transportation providers where it has a need in an area¹³.

Remitwright supports this paperwork remotely: the enrollment forms, the broker application, the tracker of what is pending with whom, and the exclusion screening routine. Field visits, vehicle inspections and driver training are between you and the broker.
