NEMT eligibility verification: checking a rider's Medicaid coverage for each ride date, and what to keep

Coverage is checked for the ride date

A rider who had Medicaid when you booked the trip may not have it on the day you drive. Federal rules make every state Medicaid program check, before it pays any claim, that the beneficiary was on its eligibility file when the service was given (42 CFR 447.45(f)). So the date that matters is the date of service, and an intake check from last month does not cover today’s ride.

Medi-Cal spells this out. It advises providers to verify eligibility on the date of service, and for most programs requires a check on that date even when the member was already verified earlier in the month. It also answers only for the current month and the 12 months before it, so in California next month’s coverage cannot be checked ahead of time.

A lapse in coverage is a denial you can catch before the van leaves, unlike a coding error that surfaces weeks later. NEMT claim denials covers the other causes.

A checking routine for a NEMT office

The rules above suggest a simple rhythm. It is an example to adapt, not a state requirement:

1. At intake. Confirm active coverage and find out who pays for this member’s rides (the state directly, a managed care plan, or a transportation broker).
2. Before each month’s first ride. Recheck every rider with a standing order or other recurring trips, since a check from last month does not reach this one.
3. On the day, where the program requires it. Medi-Cal is one such program.
4. After any sign of change. A returned letter, a new card, a rider who says a renewal packet arrived, or a call from a case manager.

What a response tells you

An eligibility response answers more than “covered or not.” Read every part of it before the trip:

• Coverage dates and program. Texas lets providers search a member’s eligibility by month and year and shows current and past coverage, including CHIP and the CSHCN Services Program.
• Who pays for rides. In New York, the eligibility response shows the member’s covered services and the transportation broker to call for prior authorization. New York’s Medicaid Transportation Policy Manual (effective August 25, 2023) adds that Medicaid denies a transportation claim when the member’s managed care plan covers rides, and that ride is billed to the plan. Indiana’s portal shows “Fee for Service + NEMT” in the Managed Care Assignment Details panel for members whose rides Verida arranges. Texas lists the member’s Medicaid health plans with contact details, and in most cases a Texas member’s managed care enrollment does not reach back to earlier dates.
• Restrictions. Texas responses flag lock-in, emergency-only, and women’s health limits. In New York, when the state’s restriction program assigns a member to one primary provider, only that provider can order the member’s rides, and transportation providers use the primary provider’s ID when they check eligibility and bill. A Texas member limited to emergency Medicaid is covered only for services tied to the emergency itself, so routine rides are not covered.
• Other coverage. Texas returns Medicare Part A, B, and C dates and other insurance with its effective dates. Medicaid pays after those payers, which third-party liability explains, and dual-eligible riders carry both Medicare and Medicaid.

Where to run the check

Each of the three states below offers a web portal and a phone line, and each also takes electronic eligibility requests from billing software.

Texas

Providers can verify through TexMedConnect, TMHP’s EDI service, the Medicaid Client Portal for Providers, or the Automated Inquiry System at 800-925-9126 or 512-335-5986. A search needs the Medicaid number, or one of three combinations: Social Security number plus last name, Social Security number plus birth date, or first name, last name, and birth date. The electronic options run around the clock, and an EDI transmission can carry up to 5,000 requests. TexMedConnect also lets an office keep eligibility lists of up to 250 members per group and 100 groups per NPI, which suits a standing-order roster. Texas also accepts its Medicaid Eligibility Verification form (H1027) as proof of coverage, including for children in foster care whose Medicaid ID has not been assigned yet.

New York

The state recommends its MEVS telephone line for offices with fewer than 50 checks a month. ePACES is free with a valid eMedNY ETIN and answers each check in real time. Software can send the 270 singly or in batches of up to 5,000. The eMedNY Call Center (800-343-9000) answers questions about eligibility checks. The New York NEMT guide covers how the state’s transportation manager authorizes trips.

California

Eligibility can be checked on the Medi-Cal website, through approved vendor software, or by telephone. When the person is eligible, the answer carries an Eligibility Verification Confirmation (EVC) number showing the inquiry was received and answered. No EVC is issued for someone who is not eligible. Medi-Cal asks providers to print the internet response and keep it in the member’s file.

The 270 and 271 behind the portals

The transaction itself is defined in 45 CFR 162.1201: a provider’s question to a health plan about a member’s eligibility, coverage, or benefits, and the plan’s answer. The required standard for medical providers is the X12 270/271, version 005010X279. Since January 1, 2013, it has also followed CAQH CORE operating rules (45 CFR 162.1203). One of them, the last name normalization rule, makes the plan remove a fixed list of suffixes and titles (JR, SR, II, III, MD, and others) and special characters from both the name you send and the name on file before comparing them. When the match succeeds but your spelling differs from the plan’s, the 271 sends back the last name as the plan stores it. Copy that spelling, because claims must match too. In Texas, the rider’s name, sex, birth date, and Medicaid number (nine digits) on the claim must exactly match TMHP’s eligibility record, and a mismatch tops TMHP’s list of reasons electronic claims are rejected.

Riders whose coverage is pending or changing

Coverage is not fixed between checks. Four changes affect rides most.

Approvals that reach back. When a state approves an application, coverage can start before the approval date. New York wants transportation providers to keep looking in its eligibility system until approval posts, and from that posting date they have 120 days to submit the trip attestation. Medi-Cal gives providers 60 days from receiving retroactive eligibility information to bill, with proof of eligibility due within one year of the month of service, and marks those months “Eligibility Reported Retroactively.” Texas does not stretch its 365-day federal deadline for late approvals. It tells providers to bill a not-yet-eligible member under the ID 999999999 or 000000000, keep the denial or rejection report, and resubmit once coverage posts. Public Law 119-21 trims that look-back starting with January 2027 applications. Expansion adults will reach back one month before the month they apply, and every other group two. Retroactive Medicaid and presumptive eligibility cover billing those rides.

Coverage that ends. Before a state cuts off or reduces a member’s coverage, the member is owed a written notice that goes out 10 or more days ahead (42 CFR 431.211). The exceptions in 42 CFR 431.213 include the member’s death, admission to an institution where the plan covers no further services, a signed request to stop, and acceptance into another state’s Medicaid. In those cases the notice can go out on the day coverage ends.

Renewals that come faster. Section 71107 of Public Law 119-21 makes states renew expansion adults every six months, starting with renewals scheduled on or after January 1, 2027. That doubles the renewals a rider in that group goes through each year, and each one is a chance to lose coverage over paperwork. Medicaid redetermination covers how renewals work.

Work requirements. Section 71119 of the same law ties coverage for many expansion adults to community engagement: 80 or more hours in a month of paid work, community service, or a work program, or school at least half-time. States must begin by January 1, 2027, though HHS can grant extra time, up to December 31, 2028, to a state making good-faith progress. A rider in this group can lose coverage over a missed report, so the monthly recheck matters even more for them.

What to keep with each trip

The eligibility response is part of the trip’s paper trail. Keep the printed or saved response, with its date, time, and confirmation number where the state issues one, alongside the trip it supports. In New York, transportation providers must keep contemporaneous records proving their right to payment for six years from the service date (18 NYCRR 504.3). The eligibility response for the ride date is part of that record. For a pending applicant, keep the denial or rejection reports too, since they become the proof that you billed on time.

Standing orders need the monthly check most

A standing order repeats until someone stops it, so a coverage lapse can turn into weeks of unpaid trips. New York, for example, can grant one prior approval that covers an extended run of rides for a rider with regular treatment like dialysis at one location. Its manual still says “prior authorization does not guarantee payment,” so a lapse in coverage can still mean a denied trip. Keep every standing-order rider on a first-of-the-month check list. When a check comes back inactive, call the rider, the case manager, or the broker that day to sort out coverage before the next ride, and note the date of each check on the trip.
