Appealing a denied NEMT claim: reconsideration, deadlines, and the trip proof to attach

Rule out the cases that are not appeals

An appeal asks a payer to reverse a final decision. Three situations need something else:

• Rejected claims. A claim that bounced at intake was never decided. Fix it and send it as an original. Texas takes a corrected electronic resubmission of a claim rejected on its 277CA response file within 95 days of the date of service.
• Claims still in process. Texas makes providers wait until a suspended claim shows as paid or denied on the R&S Report before appealing. Colorado says not to rebill or adjust a claim listed as in process.
• Your own billing errors. A wrong member ID, code, unit count, or modifier calls for a corrected or new claim under the payer’s rules, covered in corrected NEMT claims. Colorado requires providers to use every rebilling and adjustment option with its fiscal agent before asking for reconsideration.

For everything else, start with the reason code on the remittance. The five below cover most NEMT denials and point to the right response. Claim adjustment reason codes explains the full X12 set, and NEMT claim denials covers the causes behind them.

Level 1: reconsideration or first-level review

The first level is almost always the organization that processed the claim, reviewing its own decision on paper.

• Texas Medicaid fee-for-service. TMHP hears first-level appeals submitted electronically, through the Automated Inquiry System phone line, or on paper. It must receive the appeal within 120 days of the date on the R&S Report that shows the decision, and a deadline that falls on a weekend or holiday moves to the next business day. Some changes, such as a new quantity billed, cannot be appealed electronically.
• Louisiana managed care trips through MediTrans. The broker’s claims policy (revised February 2025) takes reconsideration requests up to 180 calendar days after the paid date on the remittance or the original denial date, and MediTrans decides within 30 days. Disputes are filed and tracked under the original claim number.
• Indiana fee-for-service trips through Verida. A provider starts by asking for an administrative review in Verida’s provider portal. The process applies whether or not the provider has a Verida contract.
• MTM Health in Virginia. Denied claims are appealed in MTM’s online claims portal, with the information that corrects the denial, and the window is 365 calendar days.
• Colorado fee-for-service. Providers outside the nine broker counties work problems out through the fiscal agent’s rebilling and adjustment process. Formal reconsideration is available only when circumstances beyond the provider’s control kept a claim from meeting filing rules, and billing mistakes or staff errors do not count. Once the 365-day filing period has passed, a reconsideration request has to arrive within 60 days of the last action on the claim.

Level 2: formal appeal

A second no moves the case to the state, the plan, or a formal broker appeal.

In Texas, the HHSC decision closes the matter, and a further appeal needs new evidence, so send everything the first time. A late win still pays: 42 CFR 447.45 lets a state make payment at any time to carry out a hearing decision, a court order, or a corrective action that resolves a dispute. The reprocessed claim then follows the normal cycle in how long Medicaid takes to pay.

Building the appeal packet

Reviewers decide on what you send, so assemble it once and completely. The list Texas sets for second-level appeals works as a model at any level:

1. A written explanation of the error and the outcome you are asking for.
2. The supporting documents, each labeled.
3. Copies of every remittance that shows the claim. Texas tells providers never to send the originals.
4. The incorrect information set beside the corrected information.
5. A copy of the original claim, if you have it, and a corrected, signed claim.
6. Contact center ticket numbers and any payer memos about processing problems.
7. For a timely filing dispute, certified mail receipts with a list of the claims enclosed.

Texas paper appeals follow extra format rules: one copy of the R&S Report page for each claim, only one claim circled per page, and supporting documents on separate pages rather than on the back of the report. Texas recommends certified mail with a return receipt, and a complete copy kept on file.

In the letter itself, identify the claim fully (your NPI and Medicaid provider number, the rider’s Medicaid ID, the trip or authorization number, the date of service, and the payer’s claim number), name the rule or contract term the decision conflicts with, and ask for a concrete result, such as reprocessing the base rate at the wheelchair level.

Match the trip evidence to the reason for the denial:

• Eligibility. The eligibility result you pulled for the trip date. Colorado requires providers outside the broker area to verify eligibility for every trip request and keep the documentation.
• Attendance. The signed trip record with pickup and drop-off times, plus the facility’s confirmation. WellTrans pays only for trips to covered appointments the rider actually attended.
• Miles. Odometer readings or the GPS record for the leg, and any form the payer requires. Colorado needs its verification form, completed by the treating or referring provider, for trips over 25 miles one way.
• Credentials. The driver, attendant, and vehicle records in force on the trip date. Under MTM Health’s standard agreement, no payment is made for a trip performed by an uncredentialed driver or attendant or in an uncredentialed vehicle.
• Authorization. Colorado does not pay for any trip provided without authorization from its broker or the arranging provider.

Broker audit letters run on a clock of their own. When a medical facility reports that a rider missed the appointment tied to a paid trip, WellTrans asks the provider about it in writing. Silence for 30 days counts as confirmation that the trip never happened, the right to protest is waived, and the cost comes out of the next payment. NEMT documentation requirements lists what a complete trip record holds, and the NEMT trip log template covers the fields payers check.

When the rider holds the appeal right

Some decisions concern the ride itself, and the right to appeal sits with the rider. Under federal managed care rules, a plan’s denial or limit on a requested service is an adverse benefit determination, and so is a denial of payment, unless the only problem was that the claim was not clean (42 CFR 438.400).

The rider has 60 calendar days from the notice to appeal to the plan. A provider can file on the rider’s behalf only with the rider’s written consent, and only where state law allows it. The plan has 30 calendar days to resolve a standard appeal and 72 hours for an expedited one, and either period can be extended by up to 14 days. After the plan rules, the rider can request a state fair hearing within the window the state sets, which must fall between 90 and 120 days. A plan may not take punitive action against a provider who supports a rider’s appeal or asks for a fast decision (42 CFR 438.410).

Brokers are often outside these rules. A company that contracts with the state to provide only NEMT, paid by capitation or another method that does not use state plan rates, is a NEMT PAHP under 42 CFR 438.9, and the plan appeal subpart does not apply to it. Its riders keep the right to a state fair hearing. Georgia adds its own steps: a broker must give the rider a written denial notice with appeal rights within 3 business days, the rider has 30 calendar days to appeal, and the broker has 30 days to finish its review before the rider can go on to the state.

The rider is not the backstop

A lost appeal stays with you. 42 CFR 447.15 limits Medicaid participation to providers who accept the program’s payment, plus any cost sharing the plan requires, as the full amount. MTM Health’s standard agreement bars charging a member for any reason, including nonpayment by MTM or its client, apart from a copayment one of them authorizes. WellTrans carves out one case: when a trip is denied because the rider did not attend the covered appointment, the provider may bill the rider to the extent the law allows.

Audits that later claw back paid claims run under separate notice and appeal rules. Medicaid recoupment covers them.

Keeping the appeal file ready

The appeals that win are built from records made on the day of the trip. HealthRide keeps each trip leg’s scheduled and actual times, signatures, recorded no-show waits, and GPS-recorded miles together, and the trip log exports as a PDF or spreadsheet for exactly the dates a payer questions. Credential expiration reminders warn dispatch before a driver with lapsed paperwork is assigned, which removes one common reason a trip goes unpaid.
