NEMT billing in Mississippi

Short answer

NEMT billing in Mississippi runs through one statewide coordinator. The Division of Medicaid's links page points to Modivcare for non-emergency transportation, Modivcare calls itself Mississippi's NET coordinator for eligible fee-for-service beneficiaries statewide, and MTM Health's page records the program's move to Modivcare on June 8, 2024.

Beneficiaries book at least three business days ahead unless the trip is urgent, and a transportation company is paid under its Modivcare agreement, not on a Division of Medicaid claim. Remitwright gives you a dedicated biller who reconciles Modivcare's trip data against your dispatch record, serving Mississippi transportation providers remotely. Rules for other states are on the NEMT billing by state page.

How Mississippi delivers NEMT

Single statewide NET coordinator. Modivcare states that it serves as Mississippi's coordinator for non-emergency transportation and coordinates rides for eligible fee-for-service Medicaid beneficiaries across the state. Rides are requested at least three business days in advance unless the trip is urgent, and a non-urgent request made with less notice may have to be moved to a different date.2 The Mississippi Division of Medicaid's frequently used links page carries a card for Modivcare under non-emergency transportation next to the MESA portals for providers and members and links to the health plans Magnolia Health Plan, Molina Healthcare and TrueCare. MTM Health, the previous contractor, states on its Mississippi page that as of June 8, 2024 the Mississippi NEMT program is operated by Modivcare, with MTM handling only questions about mileage reimbursement trips that took place on or before June 7, 2024.

Who you bill1

Getting enrolled as a NEMT provider in Mississippi

Medicaid provider enrollment in Mississippi runs through the MESA provider portal1. Mississippi Medicaid's non-emergency transportation runs through Modivcare as the statewide NET coordinator for fee-for-service beneficiaries, so a transportation company contracts with Modivcare rather than billing the Division of Medicaid for trips2.

Modivcare's network credentialing first. Its join page asks for six things per driver: hands-on wheelchair transport training with a PASS certificate, a current first aid and CPR certificate, defensive driving certification, a passed drug screen, a motor vehicle report showing a clean record, and a completed background check. Each vehicle needs current registration, a passed inspection where the state requires one, and proof of insurance meeting the minimum coverage, and the company carries general liability coverage for bodily injury, property damage and personal injury, sexual abuse and molestation coverage, auto liability, and workers' compensation where it has employees. Once contracted, Modivcare runs field visits to confirm vehicles meet contract standards and gives providers training built for Medicaid and Medicare NEMT.4 Enrollment with the Division of Medicaid itself, for any service billed to the state directly, runs through the MESA Portal for Providers that the Division links from its frequently used links page, and the Division's resources page carries the Medical Assistance Participation Agreement, the Provider Disclosure Form, the electronic funds transfer authorization, and six-month due lists for revalidation, license renewal and recredentialing, so a provider enrolled there tracks those dates as well.

What every trip record needs8

  • The beneficiary's name and Mississippi Medicaid identifier, the pickup and drop-off addresses, the trip date and time, and the loaded milesCMS states that at a minimum all states require the beneficiary's name and Medicaid identifier, the pickup and drop-off locations, the date and time of service and the number of miles traveled with the beneficiary in the vehicle, and that drivers document only loaded miles.
  • Modivcare's trip assignment, booked at least three business days before the appointment or flagged urgentModivcare's Mississippi page requires three business days' notice unless the trip is urgent, so the assignment is the proof that the ride was coordinated rather than arranged with the beneficiary directly.
  • The GPS ride events for each legModivcare's transportation provider page says its GPS systems automate the information that goes onto a claim and that real-time ride events reduce cancel-at-door trips and no-shows, so the recorded pickup and drop-off are what the submission rests on.
  • Confirmation that the rider is a fee-for-service beneficiaryModivcare coordinates rides for eligible fee-for-service Medicaid beneficiaries; for a member of one of the health plans the Division links, the plan's own arrangement for rides is the one to confirm before the trip is run.
  • Driver and vehicle identifiers that tie to the credentialing file Modivcare approvedThat file holds each driver's PASS certificate, first aid and CPR, defensive driving certificate, drug screen, motor vehicle report and background check, and each vehicle's registration, inspection and insurance; Section 209 of the Consolidated Appropriations Act, 2021 also requires a valid license for every driver and a clear federal exclusion check for every provider and driver.

Codes and claim format

Trips are paid under your Modivcare agreement through its web-based billing, not from a Division of Medicaid fee schedule. Modivcare's Mississippi provider page points providers to its provider portal, promises faster payment via web-based billing and describes GPS systems that automate the information for claims, so the figure to check before each submission is the rate line in that agreement for the level of service delivered. This page lists no HCPCS codes or rates.3 A claim sent to the Division of Medicaid directly follows the Gainwell EDI companion guides the Division publishes on its resources page, including the 837P professional claim, the 835 remittance advice and the 276/277 claim status transactions. A transportation company meets those only for a service it bills the state itself, not for a coordinated NET trip. For what each transport code and each origin and destination modifier means, in plain language, see the NEMT billing codes page.

Filing windows

Your Modivcare agreement sets the submission terms for coordinated trips. A trip Modivcare arranged is paid under that agreement through its web-based billing, backed by the GPS ride events its systems capture, so the record that gets it paid is the trip in Modivcare's portal submitted inside the agreement's terms rather than a claim against a Division of Medicaid deadline.3 The Division of Medicaid's own claim rules apply only to claims a provider sends to the state through the MESA Portal for Providers; this page states no state deadline, so a biller working a direct lane confirms the current rule in the Division's provider materials before the first submission.

Common rejections in Mississippi, and the fix

  • No-show billed as a completed trip

    The fixCMS says a provider cannot bill Medicaid for a no-show, and claiming loaded mileage for one is billing for services not rendered. Modivcare's ride events record what happened at the curb, so the biller reads each submission against those events and removes any no-show unless your agreement pays one.

  • Trip Modivcare never coordinated

    The fixModivcare coordinates every NET ride for fee-for-service beneficiaries, asks for three business days' notice, and may move a non-urgent request made with less notice to another date. A ride a beneficiary booked with you directly has no payer behind it, so dispatch takes trips only as Modivcare assigns them and the biller keeps the assignment with each leg.

  • Rider is a health plan member rather than fee-for-service

    The fixModivcare's Mississippi page covers fee-for-service beneficiaries, and the Division's links page lists Magnolia Health Plan, Molina Healthcare and TrueCare as separate health plans. Before carrying a plan member, the biller confirms how that plan arranges rides and who pays, so the trip is not submitted to a coordinator that never authorized it.

  • Driver or vehicle file short at a field visit

    The fixModivcare conducts field visits to confirm vehicles are up to contract standards, and its credentialing covers each driver's PASS certificate, first aid and CPR, defensive driving certificate, drug screen, motor vehicle report and background check, and each vehicle's registration, inspection and insurance. The biller keeps those expiry dates in the roster next to the trips so a lapse is renewed before trips are refused.

  • Direct claim sent to the Division in the wrong format

    The fixA claim billed to the Division of Medicaid itself follows the Gainwell 837P companion guide and the other EDI guides on the Division's resources page, and the provider has to be enrolled through the MESA Portal for Providers with its participation agreement and disclosure form on file. The biller checks the enrollment and the transaction format before the first direct claim leaves the office.

FAQ

Questions from Mississippi transportation providers

Who pays for a Mississippi Medicaid beneficiary's ride?

Modivcare, under your agreement with it. Modivcare states that it is Mississippi's coordinator for non-emergency transportation and coordinates rides for eligible fee-for-service Medicaid beneficiaries across the state, and the Division of Medicaid's frequently used links page points to Modivcare for non-emergency transportation. Your trips are paid through Modivcare's web-based billing under that agreement, so no per-trip claim for a coordinated ride goes to the Division.

Didn't MTM run Mississippi's NET program?

It did until June 2024. MTM Health's Mississippi page states that as of June 8, 2024 the Mississippi NEMT program is operated by Modivcare, and that MTM only answers questions about mileage reimbursement trips that took place on or before June 7, 2024. A transportation company that still holds MTM-era paperwork needs a Modivcare agreement to be paid for current trips.

How do we join Modivcare's Mississippi network?

Through Modivcare's credentialing. Its join page lists per driver a PASS wheelchair transport certificate, first aid and CPR, defensive driving certification, a drug screen, a motor vehicle report and a background check; per vehicle current registration, inspection where required and insurance meeting the minimum; and for the company general liability, sexual abuse and molestation, auto liability and workers' compensation coverage. Modivcare's Mississippi provider page adds a dedicated NET provider line, a provider portal, field visits and NEMT training. The full list is in the enrollment section above.

Is there a Mississippi Medicaid fee schedule for NET trips?

Not one a coordinated provider bills from. Your rate for each level of service lives in your Modivcare agreement, and submissions go through Modivcare's web-based billing with GPS data filling the claim. The Division of Medicaid's 837P companion guide and MESA enrollment apply only to services you bill the state directly.

What is the filing deadline for a Mississippi NET trip?

Your Modivcare agreement sets it. Coordinated trips are submitted through Modivcare's portal under the agreement's terms, backed by the ride events its GPS systems capture. The Division of Medicaid's own claim rules reach a transportation company only on claims sent to the state through the MESA Portal for Providers, so a biller works to the coordinator's calendar for every coordinated trip and confirms the Division's current rule before any direct claim.

Do we need to enroll in MESA to carry Modivcare riders?

Modivcare's network is what brings the trips, and the MESA Portal for Providers is the Division of Medicaid's portal for anything you bill the state directly. The Division's resources page lists what that enrollment involves: the Medical Assistance Participation Agreement, the Provider Disclosure Form, an electronic funds transfer authorization, and six-month revalidation, license and recredentialing due lists. A biller keeps both files current so neither lane stalls.

What does a trip record in Mississippi have to contain?

Every Mississippi trip record needs five things. (1) The beneficiary's name and Mississippi Medicaid identifier, the pickup and drop-off addresses, the trip date and time, and the loaded miles. (2) Modivcare's trip assignment, booked at least three business days before the appointment or flagged urgent. (3) The GPS ride events for each leg. (4) Confirmation that the rider is a fee-for-service beneficiary. (5) Driver and vehicle identifiers that tie to the credentialing file Modivcare approved.

What do you need from us to start billing Mississippi NEMT?

A signed BAA. Then your Modivcare agreement with its rate terms by level of service, a Modivcare provider portal user for the biller, your MESA login if you bill the Division for anything directly, each driver's license, motor vehicle report, drug screen, background check and training dates, the vehicle registration, inspection and insurance file, access to your dispatch records, and a count of trips per month. Any trip still unconfirmed with Modivcare from past weeks goes on the first reconciliation list so you know what is recoverable.
