What is Medicaid redetermination, and why do riders lose rides suddenly?
Medicaid redetermination is the state's regular review of whether a member still qualifies. Most members are renewed every 12 months, and expansion adults move to every six months for renewals scheduled on or after January 1, 2027. A member who misses the renewal paperwork can lose coverage for procedural reasons, and a broker that checks coverage for each ride date will then deny trips.

How a renewal works
Redetermination is the check that keeps a member on Medicaid. The regular version is called a renewal, and 42 CFR 435.916 sets the steps:
- The state tries first with data it already has. If income and other records confirm the member still qualifies, coverage renews and the member simply gets a notice.
- If it cannot, it sends a prefilled renewal form. The member has at least 30 days to return it with any proof the state asks for.
- Before ending coverage, the state must look at every basis of eligibility, and it must send notice at least 10 days before the termination date.
- A 90-day window follows. For members under MAGI income rules, a form that arrives within 90 days after coverage ends is reconsidered without a new application. States may offer the same window to other groups.
States also act between renewals when they learn of a change, such as new income, that could affect coverage.
Why coverage ends for paperwork
A procedural termination is one where coverage ends because the form or requested documents did not come back, not because the state found the member ineligible. Missing the deadline is enough. Riders in this position may still qualify, and the 90-day window lets them send the form late without starting a new application.
Six-month renewals from 2027
Section 71107 of Public Law 119-21, signed July 4, 2025, changes the schedule for one group. CMS explained the details to states in SMD 26-001 on March 6, 2026.
| Group | Renewal schedule |
|---|---|
| Adults in the expansion group, renewals scheduled on or after January 1, 2027 | Every 6 months |
| New expansion adults whose coverage starts on or after January 1, 2027 | A 6-month eligibility period from the start |
| Certain American Indians and Alaska Natives in the expansion group | Every 12 months |
| Other groups that use MAGI income rules | Every 12 months, and children under 19 keep 12 months of continuous eligibility |
| Groups that do not use MAGI rules | At least every 12 months |
The renewal steps themselves do not change. Twice as many renewals for expansion adults means twice as many chances to miss a form. Many of the same adults also face the community engagement requirement from January 1, 2027, checked at each renewal. The guide on Medicaid work requirements and NEMT covers that side. The same law also shortens retroactive coverage for expansion adults to one month, for applications made on or after January 1, 2027.
What a transportation company sees
Because the state’s notice goes to the member and not to transportation companies, a company learns about a lapse through its trips. Missouri’s NEMT manual, for example, requires its broker to confirm each rider is covered on the date of transport, and lists an ineligible participant as a reason to deny a ride.
- Recurring rides stop. Trips on a standing order for dialysis or therapy are denied once coverage lapses, even when the only problem was a missed form.
- Tell the rider or facility the same day. Quick contact with the state gives the rider the best chance to use the 90-day window.
- Rides to the review itself can count. Missouri’s broker must transport members to a Family Support Division appointment for a medical review that decides continued eligibility, without applying its usual travel standards.
Holding a regular rider’s schedule
When a regular rider’s coverage lapses, you can pause their recurring series in HealthRide instead of deleting it, then resume it once rides are approved again. The weekly pattern stays as it was. See recurring trips.
Frequently asked questions
- How often do Medicaid members go through renewal?
- Members whose income is counted under MAGI rules renew once every 12 months, and no more often. Members in groups that do not use those rules renew at least every 12 months. For renewals scheduled on or after January 1, 2027, adults in the expansion group renew every six months, except certain American Indians and Alaska Natives. Children under 19 have 12 months of continuous eligibility.
- Can a rider who lost coverage get it back without reapplying?
- Often, yes. For members whose eligibility uses MAGI income rules, a state that ends coverage because the renewal form or requested information never came back must reconsider the case without a new application if the member returns the form within 90 days after the termination date. States may allow a longer window, and may use the same process for members in other groups.
- Does anyone warn the rider before coverage ends?
- Yes. The state must send notice at least 10 days before it ends coverage, with fair hearing rights. The notice goes to the member. Transportation companies are not copied on it.
- Does the 2027 change affect children, seniors, or people with disabilities?
- Not directly. The six-month schedule applies to the expansion adult group. Other groups that use MAGI rules stay on 12-month renewals, and groups that do not use MAGI, such as many members who qualify through age or disability, keep renewals at least every 12 months. The 2027 community engagement requirement is also checked at renewal for many expansion adults.
