What Is a Medicaid Grievance? The Federal Rules and How Ride Complaints Are Handled

A rider calls her health plan to say your van left her at the clinic for an hour. That call is a Medicaid grievance. Federal rules decide how fast the plan must answer it, and the broker that arranged the ride may ask you for records.

What counts as a Medicaid grievance

Federal managed care rules define a grievance as an expression of dissatisfaction about any matter other than an adverse benefit determination (42 CFR 438.400). The rule names the quality of care or services, rudeness by a provider or employee, and failure to respect the member’s rights. It counts whether or not the member asks for anything to be fixed.

An adverse benefit determination is a decision against the member, such as denying, reducing, or stopping a service, or denying payment. A member who disagrees with one files an appeal instead. The same list includes a failure to provide services on time, as the state defines it, so in some states a ride that never came may count as a decision the member can appeal.

	Grievance	Appeal	State fair hearing
What it is	A complaint about service	A request for the plan to review a decision against the member	A hearing run by the state Medicaid agency
Ride example	The van was 40 minutes late, or the driver was rude	The plan denied a wheelchair van ride, or cut standing dialysis rides	The plan upheld its denial and the member wants the state to decide
When to file	Any time	Within 60 calendar days of the notice	In managed care, within the state’s window of 90 to 120 days from the plan’s appeal decision. In fee-for-service, within the state’s limit, at most 90 days from the notice.
Deadline to decide	Set by the state, at most 90 calendar days	At most 30 calendar days, or 72 hours when expedited	Ordinarily within 90 days
Rule	42 CFR 438.402 and 438.408	42 CFR 438.402 and 438.408	42 CFR 438.408(f), 431.221, and 431.244

The plan can extend a grievance or appeal deadline by up to 14 days if the member asks, or if it shows the state it needs more information and the delay is in the member’s interest. If the plan extends it on its own, it must give written notice of the reason within 2 calendar days.

Who handles a grievance about a ride

The rules depend on who pays for the ride. Check eligibility for the trip date to see whether the rider is in a health plan.

Who covers the ride	Grievance rules	Where the member complains
A Medicaid health plan, often through a broker it hires	The full grievance system in 42 CFR 438 subpart F. The plan stays fully responsible for work it hands to a broker (42 CFR 438.230).	The plan, or the state if the state allows it
A NEMT PAHP: a broker the state pays to provide only rides, not at state plan rates	Subpart F does not apply (42 CFR 438.402(a)). Members keep the right to a state fair hearing (42 CFR 438.9). Complaint rules come from the state and its contract with the broker.	The broker or the state, as the contract says
A state broker under the federal brokerage rule	The broker must have oversight procedures to monitor complaints and make sure drivers are courteous (42 CFR 440.170)	The broker, and sometimes a state line, such as the toll-free complaint line Georgia’s Medicaid agency keeps
Fee-for-service home and community waiver members	Since July 9, 2026, the state must run a grievance process for complaints about person-centered planning and settings (42 CFR 441.301(c)(7))	The state or its contractor

Whatever the model, the state stays responsible. CMS’s Medicaid Transportation Coverage Guide (SMD 23-006, September 28, 2023) says states must make sure members know how to file complaints and grievances and how to ask for a fair hearing, and that the state, the broker, and the ride company should all watch complaints. For how each state sets up its rides, see Medicaid managed care organization and NEMT broker.

The federal rules a health plan follows

These come from 42 CFR 438 subpart F. NEMT PAHPs are exempt, and integrated Medicare and Medicaid plans follow a combined process in 42 CFR 422.629 through 422.634 instead.

1. Filing. A member may file a grievance at any time, by phone or in writing, with the plan or the state, as the state decides.
2. Help. The plan must help members file, with interpreters and toll-free lines that have TTY and interpreter capability.
3. Acknowledgment. The plan must acknowledge every grievance.
4. Who decides. The person deciding cannot have been involved in an earlier review, or be that person’s subordinate. Clinical issues need someone with clinical expertise.
5. Resolution and notice. Within the state’s deadline, at most 90 calendar days, by a method the state sets.
6. Records. Each record lists the reason, the date received, each review date, the resolution and its date, and the member’s name (42 CFR 438.416). Plans keep them at least 10 years and must require subcontractors to keep theirs (42 CFR 438.3(u)).
7. Providers are told. Plans must explain the grievance system to every provider and subcontractor when they sign a contract (42 CFR 438.414).

How a ride grievance moves: Georgia’s example

Georgia’s NEMT policy manual (version date July 1, 2026) spells out each step its broker takes in section 920.

1. Anyone can report it. Members, their representatives, providers, the state, or any person or group that contacts the broker.
2. The broker calls back within 24 hours and notes the contact in the file.
3. The broker sends the state its findings within 5 business days, with the cause, the outcome, the fix, and any changes it made.
4. The broker writes to the person who complained with its findings and the action taken.
5. The broker may pull a provider or driver at once for an investigation or retraining, if the state requires it.
6. The broker reports every complaint monthly, naming the member, the dates of service, and the assigned transportation provider.
7. The state may override the broker’s resolution.

The state also keeps its own toll-free line for complaints from members and health care providers. The broker’s project manager or a designee must be available to answer the state about those complaints within 30 minutes (section 921.5).

Georgia treats an incident, such as an injury, accident, theft, or abuse, separately from a complaint. The broker reports incidents to the state immediately upon discovery.

What the provider must send

Your deadline is shorter than the plan’s, because the broker needs time to report. CareOregon’s transportation manual (version 1.3, February 2024) sets 3 business days for a general grievance and may require 1 business day for a serious one. It asks for objective documentation: what was seen, heard, or measured.

Send	Why it matters
The trip record, with scheduled and actual pickup and drop-off times	Shows whether the ride was on time
GPS data for the trip	Backs up the times and route
Dash camera video, if you have it	CareOregon lists footage among the records it may request
A narrative signed and dated by the driver	CareOregon lists a signed driver narrative as adequate documentation
A police report or an insurer’s payment record, for a crash	CareOregon lists either as documentation of a crash
What you changed	Georgia’s broker must report the fix and any changes to the state

CareOregon’s brokerages treat every grievance as potentially valid and preventable until the documentation proves otherwise. Send records, not only a statement. Providers there must tell a dissatisfied rider of the right to file a grievance, explain how, report it to the brokerage, and never retaliate.

Log every grievance the day it arrives with the free NEMT complaint log. If a broker asks for a corrective action plan, that is a written plan naming the cause and the fix. The full response process, with scoring rules by broker, is in how to handle NEMT broker complaints.

Grievances you file, and your own disputes

You can help a rider file. Where state law allows it and the rider gives written consent, a provider may file a grievance, request an appeal, or ask for a state fair hearing on a health plan member’s behalf (42 CFR 438.402(c)).

Your own disagreements with a broker, such as a denied claim or a complaint finding, are not member grievances. They go through the provider process in your agreement. MTM Health’s Virginia handbook (approved August 10, 2026), for example, has providers call their field monitor, use mtm-inc.net/contact, or write to MTM Health, Attention: Quality Management.
