To bill Medicaid for NEMT, enroll with your state Medicaid agency and get an NPI, then confirm eligibility and authorization before each ride. Afterward, bill the base rate and loaded miles with HCPCS codes on an 837P or CMS-1500 claim. Federal rules cap filing at 12 months, though New York allows 90 days and Arizona 6 months. Where a broker runs the rides, you usually bill the broker instead.

  • Find out who pays each trip first: the state, a broker, or a health plan. Each one has its own claim rules and deadlines.
  • Get the trip authorized before you drive, and put the authorization number in box 23 of the CMS-1500 or its electronic field.
  • Bill the base rate in trips and the mileage in loaded miles, on one claim per rider per day where your state requires it.
  • Deadlines are short: 90 days in New York, 95 in Texas, and 6 months in Arizona, under a federal ceiling of 12 months.
  • Keep a full record of every leg. Federal auditors found missing trip, driver, and vehicle records in New York NEMT claims.

Medicaid pays for a NEMT ride when four things line up: an enrolled provider, an eligible rider, an authorized trip, and a correct claim filed on time. The steps are the same in every state. The forms, codes, and deadlines depend on who pays you.

Who you bill: the state, a broker, or a health plan

Federal rule 42 CFR 440.170(a) lets a state pay transportation providers directly or run NEMT through a broker. Many states also have Medicaid health plans cover rides for their members. That choice decides where your claim goes.

Who pays you How trips reach you Where the claim goes Example
The state (fee-for-service) The rider or a facility books with you, and the state authorizes the trip where required The state’s claims system Arizona AHCCCS fee-for-service. Texas demand response providers bill TMHP (handbook, September 2026).
A broker The broker assigns each trip with a trip ID The broker Verida, Indiana fee-for-service (module published August 19, 2025)
A Medicaid health plan The plan or the broker it hires assigns trips The plan or its broker Blue Cross and Blue Shield of Texas moves its Medicaid rides from Modivcare to MTM Health on October 1, 2026
A mix The broker authorizes the trip The state New York: attest the trip with the broker, then bill eMedNY

One company often bills more than one route. Indiana shows how they combine. Most of its fee-for-service NEMT runs through the broker Verida, and providers must be enrolled with Indiana Medicaid and contracted with Verida. Stretcher, BLS, and ALS trips are booked directly with ambulance providers and billed to the state’s claims contractor, Gainwell. When a rider has a brokered and a nonbrokered trip on the same day, Indiana wants two claims, one to each payer (module version 6.1, published August 19, 2025).

Check your state’s model before anything else. Our state guides and broker directory show who runs NEMT where.

What you need before your first claim

  1. Medicaid enrollment. Your state must screen every enrolled provider (42 CFR 455.410) and revalidate each enrollment at least every 5 years (42 CFR 455.414). If you only drive for a Medicaid health plan, the state still has to screen and enroll you, though you do not have to serve fee-for-service riders. The plan may contract with you for up to 120 days while that is pending (42 CFR 438.602(b)). See how to become a Medicaid transportation provider.
  2. An NPI on every claim. Federal rule 42 CFR 431.107(b)(5) requires providers who can get an NPI to give it to the state and include it on every Medicaid claim. A company uses a Type 2 (organization) NPI from NPPES. See how to get an NPI number for NEMT.
  3. The right taxonomy code. You choose it on your NPI application, and some states check it on claims.
  4. Claim submission access. Each state has its own sign-up. New York requires an Electronic/Paper Transmitter Identification Number (ETIN) and a Certification Statement, renewed every year, before it accepts claims on paper or electronically. Arizona takes claims in its online provider portal, as 837P files, or on paper. Texas takes them through TexMedConnect, other software connected to its EDI Gateway, or on paper.
  5. Provider and driver checks. Section 1902(a)(87) of the Social Security Act, added by the Consolidated Appropriations Act, 2021, requires each state to make sure NEMT providers and drivers are not excluded from federal health programs and drivers hold valid licenses. Providers also need a process for state drug law violations and for disclosing each driver’s driving history to Medicaid. Check every owner and hire against the OIG exclusion list.

The national taxonomy list (version 26.1, effective July 1, 2026) has these transportation codes:

Taxonomy code Name in the code set
343900000X Non-emergency Medical Transport (VAN)
343800000X Secured Medical Transport (VAN)
344600000X Taxi
347C00000X Private Vehicle
342000000X Transportation Network Company
347B00000X Bus
347E00000X Transportation Broker
3416L0300X Ambulance, Land Transport

States may expect a specific one. Texas’s Medical Transportation Program handbook (September 2026) recommends 343800000X for demand response providers. See NEMT taxonomy codes.

How to bill Medicaid for NEMT, step by step

1. Check eligibility for the date of the ride

Before it pays, the state must confirm that the rider was in its eligibility file and that you were authorized to provide the service on that date (42 CFR 447.45(f)). Check eligibility in your state’s system before each trip, not once a month.

This matters more in 2027. Under the CMS rule issued June 1, 2026, states must generally start a new 80-hour monthly work requirement for many adults in the Medicaid expansion group no later than January 1, 2027. States check it at application and renewal and may check more often, so a rider can lose coverage between trips. See Medicaid work requirements and NEMT.

2. Get the trip authorized before you drive

Programs authorize trips in different ways, and the number usually goes on the claim.

  • New York. The broker sends you the trip. After the ride, you attest that it happened, and the state issues an 11-digit prior authorization number for the claim. Attest within 30 days of the date of service. The claim also needs the ordering practitioner’s NPI, or it rejects.
  • Texas. The Medical Transportation Program prior authorizes every fee-for-service trip. TMHP’s July 2021 notice says each one-way leg gets its own authorization number and its own claim.
  • Arizona fee-for-service. No prior authorization is needed when one member’s total mileage on one date is under 100 miles. Longer days need approval from the AHCCCS Prior Authorization Department.
  • Medi-Cal fee-for-service. Non-emergency trips, including wheelchair van and litter van rides, need a Treatment Authorization Request (TAR) with a legible prescription. The modifiers on the TAR and the claim must match. The only exception is a transfer from an acute care hospital to a long-term care facility.
  • Brokers. In Indiana, Verida gets any prior authorization its brokered trips need, so you do not request it yourself. Verida gives you a Trip Leg ID when it schedules the ride.

See prior authorization for NEMT.

3. Run the trip and record every leg

Your trip record is the proof behind the claim. New York’s required list, from its Medicaid Transportation Policy Manual (effective August 25, 2023), makes a good checklist for any state:

  • The rider’s name and Medicaid ID number
  • The date of the ride
  • The pickup place and time
  • The drop-off place and time
  • The vehicle’s license plate number
  • The driver’s license number
  • The driver’s full printed name and signature
  • The driver’s attestation that the trip happened, or a note that the rider did not show

New York accepts an electronic signature and a driver’s tap to confirm the trip. The system must record pickup and drop-off coordinates with a date and time stamp that cannot be changed. Arizona requires its own Daily Trip Report with every NEMT claim and denies claims that arrive without it. Use the free NEMT trip log template, and see NEMT trip documentation requirements.

4. Code the trip

Most NEMT claims have a base line and a mileage line, and some have a wait time line.

  • Base rate. One code for the level of service, such as A0130 for a wheelchair van, billed in trips.
  • Mileage. Loaded miles, with a code such as S0209 for wheelchair van miles, billed in miles. CMS says empty miles generally cannot be paid, though a state may cover them in limited cases. South Dakota pays some on community transportation trips of 21 miles or more outside city limits, and Arizona bars them.
  • Wait time. T2007, in half-hour units, only where your program pays it.
  • Extra riders and attendants. Each state bills them its own way. South Dakota adds TK for a second rider, Indiana bills T2004 or adds TT, and T2001 bills an attendant where it is paid.
  • Modifiers. Up to four per line, such as TN for rural trips in Arizona, or an origin and destination pair where your state requires one.

Arizona wants every trip for one member on one date on a single claim: base rate on line 1, loaded miles on line 2, and wait time on line 3. A base-only claim and a separate mileage-only claim are denied as split billing. The same code can mean different things in different states, so read NEMT billing codes next to your own fee schedule.

5. Fill out the claim

The CMS-1500 is the standard paper claim, and the 837P is its electronic version, the HIPAA standard under 45 CFR 162.1102. These are the boxes that matter most on a NEMT claim, from the NUCC instructions (version 13.0, July 2025) and state manuals:

Box What it holds NEMT notes
1a Insured’s ID number The rider’s Medicaid ID, as shown on the card
19 Additional claim information Arizona (since November 1, 2022) and South Dakota want the pickup and drop-off addresses here. Medi-Cal wants full pickup and drop-off addresses, with city and ZIP code, when you bill mileage, and the time and destination of each trip on round trips and repeat trips the same day.
21 Diagnosis codes Texas requires Z753 on Medical Transportation Program claims
22 Resubmission code 7 replaces a prior claim and 8 voids one. Leave it blank on first claims.
23 Prior authorization number No hyphens or spaces
24A Date of service The date of the ride
24B Place of service Texas recommends 09 on paper claims and uses 99, “other place of service,” in TexMedConnect. Medi-Cal uses 21 when a hospital inpatient rides out and back.
24D Procedure code and modifiers The HCPCS code plus up to four two-character modifiers
24F Charges South Dakota requires your usual and customary charge. Its fee schedule is the most it pays.
24G Units Trips on the base line, loaded miles on the mileage line
24J Rendering provider NPI Only when it differs from box 33a
25 Federal tax ID Your EIN, or SSN for a sole owner
32 Service facility location Medi-Cal wants the hospital’s address and NPI when a hospital inpatient rides to an appointment and back
33, 33a, 33b Billing provider, NPI, other ID 33b can hold your taxonomy code after the ZZ qualifier

New York does not use the CMS-1500. Paper claims go on its eMedNY-000201 form (Form A), with the prior authorization number in field 19, place of service 99 in field 20, and the ordering provider’s NPI in field 23. See the box-by-box CMS-1500 guide for NEMT and how to submit NEMT claims electronically.

An Arizona example. A wheelchair rider in Phoenix goes from home to dialysis and back on one date, 12 loaded miles each way. These amounts use AHCCCS fee-for-service rates effective October 1, 2026, and the distances are example numbers.

Line Box 24D Box 24G Rate Amount
1 A0130 2 trips $11.15 $22.30
2 S0209 24 miles $1.54 $36.96
Total $59.26

The trip starts in the Phoenix metro area, so no TN modifier. The day’s mileage is under 100, so no prior authorization. The Daily Trip Report goes with the claim, and on a paper claim the addresses go in box 19.

6. Submit before the deadline

File daily or weekly, and keep every acceptance and rejection report. They prove you filed on time. Texas lets providers use TMHP rejection reports or Return to Provider letters as proof of meeting its 365-day limit. The next section lists the deadlines.

7. Read the remittance and fix what failed

Each payment comes with a remittance advice, on paper, as a PDF, or as an 835 file. Texas sends a weekly Remittance and Status report. Every denied or reduced line carries a standard adjustment reason code:

Code What it means (X12) The usual NEMT fix
16 Claim lacks information or has billing errors Add the missing item, such as the authorization number or addresses
18 Exact duplicate claim or service For a second trip the same day, add the modifier your state wants, such as XE in Indiana
27 Expenses incurred after coverage terminated Check eligibility on the date of the ride
29 The time limit for filing has expired Appeal only with proof you filed on time
4 Procedure code inconsistent with the modifier Match the modifiers to the code and the authorization
197 Authorization absent Get the authorization and resubmit if your state allows
109 Not covered by this payer Send it to the right payer, such as the rider’s health plan or broker

Send a correction with frequency code 7 in box 22 and the payer’s original claim number. See how to read remittance advice, corrected NEMT claims, and NEMT claim denials.

Medicaid claim deadlines for NEMT

Federal rule 42 CFR 447.45(d)(1) requires every state to make providers submit claims within 12 months of the date of service. States can set shorter limits, and many do. See Medicaid timely filing limits.

Payer First claim due Fixes and appeals Source date
Federal ceiling 12 months from the date of service 42 CFR 447.45
New York Medicaid 90 days from the date of service. Attest the trip within 30 days. With retroactive eligibility, attest up to 120 days after eligibility is set Billing guidelines, August 5, 2026
Texas Medical Transportation Program 95 days from the date of service, 365 days for out-of-state providers New providers: 95 days from getting their provider identifier and 365 days from the ride Handbook, September 2026
Arizona AHCCCS fee-for-service 6 months after the date of service Clean claim or corrections within 12 months Chapter 4, revised November 3, 2025
Medi-Cal fee-for-service 6 months after the month of service Months 7 to 9 pay 75 percent and months 10 to 12 pay 50 percent. After that, denied. Appeal within 90 days of the remittance. Provider manual pages updated February and May 2025
South Dakota Medicaid 6 months after the month of service Reconsideration within the filing period or 3 months after a denial Manual, updated August 2026

How long Medicaid takes to pay

The federal payment standard is written for practitioners: 90 percent of their clean claims paid within 30 days of receipt and 99 percent within 90 days. All other claims must be paid within 12 months of receipt (42 CFR 447.45(d)). A clean claim is one the state can process without asking you or anyone else for more information.

Health plan contracts must hold plans to the same 30-day and 90-day standard, unless the plan and its providers agree to a different schedule written into the contract (42 CFR 447.46). Texas pays Medical Transportation Program claims weekly. Broker contracts set their own schedules. See how long Medicaid takes to pay.

Billing a broker instead of the state

In a broker program, the broker holds the Medicaid contract and pays you from its own rate sheet. You submit claims in its portal, tied to its trip ID.

Indiana’s fee-for-service broker, Verida, shows how it works (module published August 19, 2025):

  • Joining. You sign Verida’s provider agreement and rate agreement, and finish its credentialing within 60 days.
  • Rates. Verida’s rate schedule is based on the state’s Professional Fee Schedule, and Verida may negotiate higher or special rates with each provider.
  • Payment. Clean claims sent to Verida by Wednesday are paid within 14 days, by check or direct deposit, with a remittance advice for each payment cycle.
  • Disputes. Start with an administrative review in Verida’s provider portal, then file a written appeal if that does not settle it.

Your state enrollment still matters in many broker states. Indiana requires providers in the Verida network to be enrolled Indiana Medicaid providers too. For trip IDs, portals, payment cycles, and appeals at each major broker, see how to bill NEMT brokers.

Billing a Medicaid health plan

When a rider is in a Medicaid managed care organization, the plan decides who carries and pays for the ride. In Texas, health plans approve managed care NEMT, and the state’s Medical Transportation Program handbook does not apply to their members.

Many plans hand rides to a broker. Blue Cross and Blue Shield of Texas moves its Medicaid members from Modivcare to MTM Health on October 1, 2026. Its August 26, 2026 notice says recurring and already scheduled trips after that date go to MTM Health. A change like that moves your claims too. Ask each plan three questions: which broker handles its rides, where claims go, and what its filing deadline is.

The federal rules still apply. The state must screen and enroll you as a plan network provider (42 CFR 438.602(b)), and the plan’s contract sets its payment schedule under 42 CFR 447.46.

Rules every Medicaid NEMT claim must follow

  • Medicaid’s payment is payment in full. Under 42 CFR 447.15, you accept what Medicaid pays plus any cost sharing the state plan allows. CMS’s transportation guide (September 28, 2023) says NEMT cost sharing is allowed only when the state covers NEMT as an optional medical service, and it must be nominal.
  • No claims for no-shows where the state forbids them. Texas says providers cannot bill Texas Medicaid or Medicaid clients for missed appointments. See billing for NEMT no-shows.
  • Loaded miles, as a rule. CMS’s transportation guide says miles with no rider on board generally cannot be paid, though states may build them into rates or cover them in limited cases with CMS approval. Arizona bars any claim for unloaded mileage, including a trip to pick up a member’s prescription. See loaded miles.
  • Payment goes to you. 42 CFR 447.10 bars Medicaid payments to or through a factoring company. A billing agent may receive payment in your name only if its fee is tied to the cost of billing and not to what it collects. See NEMT factoring.
  • Medicare does not pay NEMT van codes. The CMS HCPCS file (October 2026) marks A0130, T2003, S0209, and the other non-emergency transportation codes as not payable by Medicare.
  • Other coverage comes first. When the state has already found that another insurer is probably liable, it generally must reject the claim and return it to you so that insurer’s share is settled first (42 CFR 433.139). See third party liability.
  • Keep the records. Every provider agreement requires you to keep records of the services you give and to hand them over on request (42 CFR 431.107). New York requires each leg’s trip record for 6 years from the date of payment.

What auditors find in NEMT claims

The HHS Office of Inspector General audits state NEMT programs, and its findings show what a weak record costs. In a September 2022 audit of New York City NEMT payments for 2018 and 2019 (report A-02-21-01001), only 17 of 100 sampled payments met federal and state rules. Another 41 did not, and for 42 the auditors could not tell. Among the problems:

Finding in the New York audit Sampled payments Result
No valid practitioner’s order behind the authorization 22 Unallowable
Trip not adequately documented (date, pickup, drop-off, driver, or vehicle missing, or no record at all) 13 Unallowable
Driver qualification rules not met 7 Unallowable
No proof the vehicle met inspection and licensing rules 21 Could not be confirmed
No proof the driver was licensed for the vehicle 10 Could not be confirmed

OIG estimated that New York improperly claimed at least $84,329,893 in federal Medicaid money for payments that did not meet the rules. On May 28, 2026, OIG announced a new series of audits of NEMT payments in selected states. Its notice names the basics it will test against: prior authorization backed by a practitioner’s order, providers lawfully allowed to transport, and records that support each service.

Build your files so any claim can be proven years later:

  1. Keep one record per leg with every field your state lists, and match it to the claim line.
  2. File the authorization with the trip record, including the practitioner’s order where your state requires one.
  3. Keep dated copies of vehicle inspections, registrations, and permits that cover every date you billed.
  4. Keep each driver’s license, driving record, and exclusion checks current and on file.
  5. Audit yourself. Pick 10 paid claims a month and check each against its trip record, authorization, driver file, and vehicle file.

Frequently asked questions

Do I bill Medicaid directly or go through a broker?

It depends on your state and the rider's plan. Arizona and South Dakota pay fee-for-service NEMT providers directly. In broker programs, such as Indiana fee-for-service with Verida, you submit claims for brokered trips to the broker. New York mixes the two: you confirm the trip with the broker, then bill the state. Riders in a Medicaid health plan get rides through the plan or the broker it hires.

What claim form do I use to bill Medicaid for NEMT?

Most programs take the paper CMS-1500 or its electronic version, the 837P. Arizona, South Dakota, and Medi-Cal all use them, and Arizona also requires its Daily Trip Report with every NEMT claim. New York is different: paper claims go on its own eMedNY-000201 form, called Form A, and electronic claims use the 837P.

How long do I have to submit a Medicaid NEMT claim?

Federal rule 42 CFR 447.45 caps the limit at 12 months from the date of service, and states can set shorter ones. As of September 2026, New York allows 90 days, Texas allows 95 days for in-state providers, and Arizona allows 6 months. Medi-Cal and South Dakota allow 6 months after the month of service. Submit weekly so no deadline gets close.

Can I bill Medicaid when the rider does not show up?

Usually not, because Medicaid pays for rides given, not rides scheduled. Texas says providers cannot bill Texas Medicaid or Medicaid clients for missed appointments. Medi-Cal is an exception: its manual lets ground providers bill a dry run, when they respond to a call but do not carry the rider, with modifiers DS and QN. Record the no-show with the time and your attempts to reach the rider, as your program requires, and cancel early when you know a rider will not ride.

Can I charge the rider if Medicaid denies the claim?

Generally no. Federal rule 42 CFR 447.15 limits Medicaid to providers who accept its payment as payment in full, plus any cost sharing the state plan allows. CMS says cost sharing is allowed for NEMT only in some cases and must be nominal. Fix the claim or appeal the denial instead of billing the rider.

What if the rider's Medicaid is approved after the ride?

States must pay for covered rides in a retroactive eligibility period, CMS says in its September 2023 transportation guide. If the rider paid you, you may need to refund that money first and then bill Medicaid. New York lets you attest the trip up to 120 days after eligibility is set, and Arizona counts its 6-month limit from the date eligibility is posted.

Can a billing service or factoring company get paid for me?

A billing service can, within limits. Under 42 CFR 447.10, Medicaid may pay a billing agent in your name only if its fee is tied to the cost of billing, not a percentage of what it bills or collects, and does not depend on collection. Medicaid may never pay a factoring company that buys your receivables, directly or by power of attorney.
