Medicaid Renewal: How Redetermination Works and How Not to Lose Coverage

A Medicaid renewal is the check your state runs, usually once a year, to confirm you still qualify. Many people are renewed automatically from data the state already has. Others get a renewal form in the mail and lose coverage only because it never came back.

That second group is bigger than most people think. During the 2023 to 2024 unwinding, KFF found that 69% of people who were dropped lost Medicaid for paperwork or procedural reasons, not because their income was too high.

This guide walks through how redetermination works under the federal rules, what the deadlines are, what to do after a move, and how to get coverage back if it already ended. Rules come from 42 CFR 435.916, CMS guidance on Medicaid.gov, and state agency pages checked on October 30, 2026.

Key Takeaways

• Your state must first try to renew you without contacting you (ex parte). If it can’t, it mails a prefilled form and must give you at least 30 days to answer.
• Coverage ended because the form was late? Federal rules let you send it within 90 days of the end date and be reconsidered without a new application.
• You get at least 10 days of notice before coverage stops. Asking for a fair hearing before the end date usually keeps your benefits running until a decision.
• Children under 19 keep Medicaid for 12 months at a time, even if family income rises.
• For renewals scheduled on or after January 1, 2027, most expansion adults (ages 19 to 64) will renew every 6 months instead of every 12.

What is a Medicaid renewal, and is it the same as redetermination?

Yes, mostly. A Medicaid renewal is the scheduled review of your eligibility. Redetermination is the broader term: it covers that renewal plus any review triggered by a change you report, like a new job or a move. States also say recertification or case review. Each one decides whether you still qualify.

North Carolina’s fact sheet lists the names side by side: “eligibility redetermination, renewal, ex-parté review or case review (all mean the same thing).” Other states use “annual review” or “recertification.” If a letter uses any of these words, treat it as a renewal and read it the same day.

The federal rule behind all of it is 42 CFR 435.916. It sets the order of steps every state follows: check its own data first, then send a form only if it has to, then give you time to answer, then consider every other way you might qualify before ending coverage.

That last step matters. Before cutting you off, the state “must consider all bases of eligibility.” A parent whose income rose, for example, might no longer fit the parent group but could still qualify through a disability or a medically needy pathway. See Medicaid income limits by state for the main groups.

How often do you need to renew Medicaid?

Most people renew Medicaid once every 12 months. For groups whose eligibility is based on income (MAGI), such as children, parents and pregnant people, federal rules say once a year and no more often. Seniors and people with disabilities renew at least yearly. From 2027, most expansion adults renew every 6 months.

The timing depends on which group you are in, so it helps to know your category. Your approval letter usually names it. Here is how the schedule breaks down right now and after the 2027 change:

Who you are	How often you renew	Source of the rule
Children under 19	Every 12 months, with coverage locked in for those 12 months	42 CFR 435.926
Parents, caretakers, pregnant people	Every 12 months, no more often	42 CFR 435.916(a)
Expansion adults 19 to 64	Every 12 months now; every 6 months for renewals scheduled on or after Jan. 1, 2027	CMS SMD #26-001
Age 65+, blind or disabled (non-MAGI)	At least every 12 months	42 CFR 435.916(b)

A change can trigger a review between renewals. If you report a raise, a new household member or a move, the state must “promptly redetermine eligibility.” For income-based groups, it can only ask about the change itself, not reopen your whole file.

If that mid-year review has everything it needs, the state may start a fresh 12-month period from that date. So reporting a change early can push your next renewal back rather than add a second one.

The 2027 switch to six-month renewals

Section 71107 of the 2025 budget law (Public Law 119-21, which CMS calls the Working Families Tax Cut legislation) requires states to renew most adult expansion enrollees “once every six months, beginning with renewals scheduled on or after January 1, 2027.”

CMS’s March 6, 2026 letter to states, SMD #26-001, says the steps do not change. States still try an automatic renewal first, still send a prefilled form when they need more, and still give at least 30 days to return it. Only the frequency changes.

The 6-month cycle does not apply to children, parents in the parent group, pregnant people, seniors, people with disabilities, or certain American Indians and Alaska Natives. It also does not apply in states that cover adults only through a partial 1115 waiver. That means one household can have two calendars.

A couple might renew every 6 months while their kids renew every 12. Because states must act promptly on any news of a change, one person’s renewal can also trigger a review for someone else in the home. Keep every letter, since dates may differ by person.

Many of the same adults will also face a new work or community engagement rule starting January 1, 2027, checked at each renewal. That rule, its 80-hour monthly test and its exemptions are covered in our guide to Medicaid work requirements. It works differently from the SNAP work rules.

Will Medicaid renew automatically?

Often, yes. Federal rules require your state to try an ex parte renewal first, using wage records, tax data and other sources it can check. If that data shows you still qualify, you are renewed without filling out anything. During the unwinding, KFF found 61% of people who kept coverage were renewed this way.

The rule is direct. The agency “must make a redetermination of eligibility without requiring information from the individual if able to do so.” It then sends you a notice explaining the decision and what it was based on.

You do not have to sign or return that notice if everything in it is right. You do have to tell the agency if something is wrong. A wrong household size, an old address or income that is out of date can all cause trouble at the next review, so read the notice line by line.

Automatic renewal can be harder if your income changes month to month, if you are self-employed, if you have income the state cannot see in its databases, or if your eligibility depends on assets. In those cases, expect a form.

North Carolina describes the order plainly: your caseworker “will try to complete your recertification using information from electronic resources, without contacting you,” and mails a letter only when more is needed. If you get no letter at all, call to confirm you were renewed rather than assuming it.

What comes in a Medicaid renewal packet, and how long do you have?

If the state cannot renew you automatically, it mails a renewal form filled in with what it knows. You fix anything wrong, add what it asks for, sign it and send it back. For income-based Medicaid, federal rules give you at least 30 days from the date on the form, and you can’t be required to come in for an interview.

The packet usually has three parts: the prefilled form, a list of documents the state wants, and a due date. The due date is the number to circle. Thirty days is the floor, not a target. States can give more, and your letter will say exactly how long you have.

For seniors and people with disabilities, the federal rule says the state “may adopt” the same prefilled form and 30-day process. It is a state choice for those groups, so read your own letter for the deadline instead of assuming 30 days.

What to have ready before the form arrives

The state can only ask for what it needs to renew you. In practice, requests tend to come from this list:

• Recent pay stubs or a letter from your employer
• Self-employment records, such as a profit and loss statement or your latest tax return
• Award letters for Social Security, SSI, unemployment, a pension or child support
• Proof of a new address, such as a lease or a utility bill
• Bank statements, if your eligibility group counts savings or other assets
• Information about any new health insurance, including Medicare

Keep copies of everything you send. Write down the date, the method you used and, if you called, the name of the person and a reference number. That record is what you will lean on if the state later says it never received your form.

Ways to send it back

Federal rules require states to accept your renewal through any of the ways they accept applications: online, by phone, by mail, in person or other common electronic means. Online is usually fastest because you get a confirmation right away.

Two state examples show how this looks. Texas HHSC sends a letter when it is time to renew; you can sign the form electronically on Your Texas Benefits or call 2-1-1 for a paper form. North Carolina lets people with an enhanced ePASS account update their address and return renewal information online.

Not sure which agency runs Medicaid in your state? Medicaid.gov keeps a state-by-state contact list. Your health plan may be able to tell you your renewal month, and many plans post renewal help for members. The form itself still goes back to the state, not to the plan.

Which deadlines protect you during a Medicaid renewal?

Five federal time limits shape every Medicaid renewal: at least 30 days to return the form, at least 10 days of notice before coverage ends, 90 days after it ends to send a late form, up to 90 days from the notice to ask for a hearing, and a hearing decision ordinarily within 90 days.

The windows overlap, which is why it pays to see them on a calendar. Here is a made-up example to show the math. Say your form is dated March 3. You have until at least April 2 to return it. You miss it, and on April 15 the state mails a notice that coverage ends April 30.

You now have three tracks. Ask for a hearing before April 30 and federal rules say coverage generally continues until the hearing decision. Or send the form any time through July 29, 90 days after April 30, and the state must reconsider without a new application. Or apply for Marketplace coverage after April 30.

The hearing window is the one that varies most. The federal rule allows “a reasonable time, not to exceed 90 days” from the date the notice is mailed. North Carolina, for example, gives 60 days and continues Medicaid if you appeal within 10 business days of the notice. Your notice must state your state’s deadline.

Why do people lose Medicaid at renewal?

Most people who lose Medicaid at renewal lose it for procedural reasons: the form went to an old address, it came back late or incomplete, or a requested document never arrived. KFF’s unwinding analysis found 69% of disenrollments were procedural and only 31% were people found ineligible.

KFF counted at least 25.2 million people disenrolled and 56.4 million renewed by September 12, 2024. KFF explains that these losses “can occur when the state has outdated contact information or because the enrollee does not understand or otherwise does not complete renewal packets.”

The unwinding is over, but the causes have not changed. These are the gaps that most often end coverage for someone who still qualifies:

• Mail sent to an old address. The form never reaches you, and the deadline passes.
• A missing signature. The form has to be signed, and an unsigned one can be sent back to you, eating up your time.
• Partial documents. The form comes back, but the pay stubs or bank statements do not.
• Unanswered follow-up letters. A second request for information has its own deadline.
• Assuming the plan handles it. Your health plan can remind you, but only the state renews you.

Loss for real ineligibility looks different. If your income is now above the limit for every group you could fit, the notice should say so and explain your options, including Marketplace coverage. Federal rules require the state to check you for those other programs before closing your case.

What if you moved or your address changed?

Report a new address to your state Medicaid agency right away, online, by phone, by mail or in person. Federal rules require states to accept change reports. From January 1, 2027, states must also pull addresses from Postal Service data and health plans, but your own update is still safest.

The 2025 law adds address checks. By January 1, 2027, each state needs a process to get addresses from “mail returned by the U.S. Postal Service with a forwarding address,” the Postal Service’s National Change of Address database, and managed care plans. Plans must pass along address updates you give them.

That helps, but it does not replace telling the state. A forwarding order can expire, and a plan may not get your new address until after a renewal letter is already in the mail. A one-minute update online beats a lost form.

Moving to another state is different. Medicaid is run by each state for its own residents, so your coverage does not travel with you. You apply in the new state and tell the old one you have moved. For children, leaving the state is one of the few reasons continuous eligibility can end early.

Plan the move so you do not have a gap. Apply in the new state as soon as you have an address there. Under 42 CFR 435.912, a state has up to 45 days to decide most applications and up to 90 days when you apply based on disability.

My Medicaid was cancelled. How do I get it back?

If coverage ended because you did not return the renewal form or documents, send them within 90 days of the end date. For income-based Medicaid, the state must then reconsider you without a new application. After 90 days, or if you were found ineligible, you generally apply again.

The state must “reconsider in a timely manner” anyone cut off for a missing form “if the individual subsequently submits the renewal form within 90 days after the date of termination, or a longer period elected by the State, without requiring a new application.” States may allow longer.

When you send the late form, say clearly that you are asking for reconsideration of a renewal, and include the case number from your notice. Call a few days later to confirm it was logged as a renewal, not as a brand new application.

If you have to reapply

Reapplying starts a new application with the same 45 or 90 day decision clock described above. Ask about retroactive coverage when you apply. Today Medicaid can cover bills from up to three months before the month you apply, if you qualified in those months.

That window is shrinking. For applications submitted on or after January 1, 2027, the 2025 law cuts it to one month for expansion adults and two months for everyone else, according to the Missouri Department of Social Services. If coverage has lapsed, applying before that date protects more of your old bills.

Coverage while you wait

If you are found ineligible or a gap is unavoidable, look at a Marketplace plan.

HealthCare.gov says that if you “lost Medicaid or Children’s Health Insurance Program (CHIP) coverage in the past 90 days, you may qualify for a Special Enrollment Period.” Our ACA open enrollment guide covers how that coverage and its subsidies work.

Federal rules also require the state to screen you for other coverage programs when it finds you ineligible and pass your information along. If you get a Marketplace notice soon after a Medicaid denial, that may be why. You still have to choose a plan yourself.

How do you appeal a Medicaid renewal decision?

Ask for a state fair hearing using the instructions on your notice. Do it before the date coverage ends if you can, because benefits generally continue until the decision. You have up to 90 days from the notice under federal rules, though your state may set a shorter deadline.

The notice is your starting point. Under the federal fair hearing rules, it must be sent at least 10 days before the date of action, and it must explain the decision and your hearing rights. If you think the state got your income, household or address wrong, a hearing is how you make it look again.

Keeping coverage during the appeal has one catch. If you lose the hearing, the state “may institute recovery procedures” to recoup the cost of services you got only because benefits continued. Weigh that before asking for continued benefits if your case is weak.

Once you ask, the state must ordinarily issue a final decision within 90 days of your request. If waiting could seriously harm your health, ask for an expedited hearing. For eligibility claims, federal rules set a decision deadline of no later than 7 working days after an expedited request is received.

Bring the same file you built for the renewal: copies of the form, proof of when you sent it, pay stubs and any letters. If you want help, a local legal aid office may represent you for free. Some cases are also fixed by a caseworker before the hearing date once the missing papers turn up.

Do children have to renew Medicaid every year?

Children still have a renewal every 12 months, but between renewals their coverage is locked in. Since January 1, 2024, every state must give children under 19 in Medicaid and CHIP 12 months of continuous eligibility. A raise or a change in family size does not end a child’s coverage mid-year.

The rule comes from section 5112 of the Consolidated Appropriations Act, 2023, and is written into 42 CFR 435.926. A child’s 12-month period starts when coverage begins or at the most recent renewal.

Coverage can end early only if the child turns 19, the family asks to end it, the child moves out of state, coverage was granted by agency error or fraud, or the child dies. A parent’s own Medicaid can end at renewal while the child’s coverage continues.

Kids moving between Medicaid and CHIP at renewal is normal too. The CHIP program page and our CHIP income limits guide explain where that line falls. Postpartum coverage follows its own rules, covered in Medicaid for pregnant women.

Is renewal different if you are 65 or older or have a disability?

Somewhat. Seniors and people with disabilities usually qualify under non-MAGI rules that can include an asset test. The state must still renew them at least every 12 months and try an automatic renewal first. The 30-day form and 90-day reconsideration steps are optional for these groups, so the letter’s dates control.

The federal rule also lets states treat a disability “as continuing” until a review team decides it no longer meets the state’s definition. In other words, a yearly renewal does not have to retest your disability itself.

Bank balances are what most often trip up this group. If your state counts resources, it may ask for statements at each renewal. A balance that crept above the limit can end coverage, even when income did not change. Our Medicaid spend down guide covers how people with higher incomes or medical bills can still qualify.

People with both Medicare and Medicaid should open every Medicaid letter. Losing Medicaid can also end help with Medicare costs. If that happens, check the separate Medicare Savings Programs, which have their own limits, and read Medicare vs Medicaid for how the two programs fit together.

How can you make your next Medicaid renewal go smoothly?

The best time to prepare is the month after you are renewed, when your documents are fresh. A few small habits cover almost every procedural risk described above:

1. Find your renewal month. It is on your last approval notice, or your state portal or health plan can tell you. Put a reminder 6 weeks before it, and a second one 6 months later if you are an expansion adult from 2027.
2. Set up the state’s online account. It is the fastest way to see letters, update an address and upload documents.
3. Keep one folder. Pay stubs, award letters and bank statements from the last few months, plus copies of whatever you sent last time.
4. Update your address the week you move. Do it with the state, not just the Postal Service.
5. Read every notice the day it arrives. Write the due date on the envelope. If the date is close, call.

If a deadline still slips, remember the order of rescue: ask for a hearing before the end date, send the form within 90 days after it, then reapply. Each option is a little harder than the one before, so the sooner you act the better.
