Medicaid redetermination is the process your state uses to check whether you still qualify for Medicaid coverage. Every state is required to review each enrollee’s eligibility periodically, typically once a year, by verifying your income, household size, and residency. If your state can confirm your eligibility using data it already has access to, you may not need to do anything. If it can’t, you’ll receive a renewal form in the mail that you must complete and return within a set deadline to keep your coverage.
This process became a major source of confusion and coverage loss starting in 2023, when states resumed redeterminations after a three-year pause during the COVID-19 pandemic. Millions of people went through redetermination for the first time in years, and many lost coverage not because they were ineligible, but because they missed paperwork deadlines.
How the Redetermination Process Works
Redetermination happens in stages, and your state is required to follow federal rules at each one.
First, your state attempts what’s called an “ex parte” renewal. This means it checks the information already in your file, along with data from other government sources like tax records, to see if it can confirm your eligibility without contacting you. If everything checks out, your coverage is renewed automatically and you don’t need to lift a finger.
If your state can’t verify eligibility that way, it sends you a prepopulated renewal form. This form contains the information the state already has on file about your income, address, and household. Your job is to review it, correct anything that’s changed, and provide any documentation the state needs. You get a minimum of 30 days to return the form. Before your state can terminate your coverage, it must also check whether you qualify under any other Medicaid category, give you at least 10 days’ advance notice of the decision, and offer you the right to appeal.
Why Redetermination Became a Crisis in 2023
In March 2020, Congress passed the Families First Coronavirus Response Act, which gave states extra federal Medicaid funding on the condition that they kept nearly all enrollees covered. This “continuous enrollment” rule meant that for roughly three years, no one was dropped from Medicaid for changes in income or for failing to return paperwork. Enrollment swelled to historic levels.
That protection ended on March 31, 2023. States then had 12 months to initiate renewal reviews for every person enrolled and up to 14 months to complete them. States could begin the process as early as February 2023, but no one could actually be disenrolled before April 1, 2023. Nearly all states originally planned to finish their first round of these renewals by June 2024, though many received approval to extend their timelines through June 2025.
The scale was unprecedented. States had to review tens of millions of cases in a compressed window, and many enrollees had moved, changed jobs, or simply never received their renewal forms because their addresses were outdated after three years without contact.
Procedural Disenrollment: The Paperwork Problem
The biggest concern with redetermination isn’t people losing coverage because they earn too much. It’s people losing coverage because of missed paperwork. These are called procedural disenrollments, and they happen when someone fails to return a renewal form, doesn’t provide requested documents, or can’t be reached by their state agency.
A significant share of people disenrolled during the post-pandemic unwinding lost coverage for purely procedural reasons, not because they were actually ineligible. Common scenarios include a renewal form sent to an old address, a form that got lost in a pile of mail, or a person who didn’t realize they needed to respond at all because they’d been automatically enrolled for years. Research published in JAMA Health Forum noted that millions were projected to lose coverage “for solely procedural reasons (e.g., after missing a required renewal form following a change in address) despite remaining eligible.”
This is preventable. If you’re on Medicaid, keeping your contact information current with your state’s Medicaid agency is the single most important thing you can do to avoid losing coverage during redetermination.
What You Need to Provide
When your state can’t confirm your eligibility automatically, you’ll need to verify specific details. The exact documents depend on what your state needs to check, but the most common categories are:
- Income: Recent pay stubs, a tax return, or a letter from an employer showing your current wages. If your income has changed, documents showing the new amount or when a job ended.
- Residency: A utility bill, lease agreement, or other document showing your current address in the state.
- Household size: Information about who lives in your home, which affects the income threshold you’re measured against.
- Citizenship or immigration status: If this needs to be verified, you typically get 95 days rather than the standard deadline.
Your renewal notice will list exactly which documents are needed for your situation. Don’t ignore this notice. Even if you believe nothing has changed, failing to respond is treated the same as being ineligible.
Income Limits for Eligibility
Medicaid eligibility thresholds vary by state, the category you qualify under (such as parent, pregnant person, child, or adult in an expansion state), and your household size. In states that expanded Medicaid under the Affordable Care Act, most adults qualify with household incomes up to 138% of the federal poverty level. For 2024, the federal poverty level for a family of four in the contiguous U.S. is $31,200, so 138% of that works out to roughly $43,056.
Children typically qualify at higher income levels than adults, and pregnant individuals often qualify at even higher thresholds. States that did not expand Medicaid have much narrower eligibility, sometimes covering only parents with extremely low incomes and excluding most childless adults entirely. Your state Medicaid office or your renewal notice will tell you which income limit applies to your specific situation.
What Happens If You Lose Coverage
If your redetermination results in a loss of Medicaid, you have options. First, you can appeal the decision. Every state must give you the right to a fair hearing, and if the disenrollment was procedural (you were dropped for not returning a form, not because your income was too high), you may be able to get your coverage reinstated by submitting the missing information.
If you’re no longer eligible for Medicaid because your income has increased, losing coverage qualifies you for a Special Enrollment Period on the Health Insurance Marketplace. This lets you shop for a plan outside of the normal open enrollment window. You’ll need to submit documents showing the coverage you lost and the date it ended. Depending on your income, you may qualify for subsidies that significantly reduce your monthly premiums on a Marketplace plan.
Acting quickly matters. The Special Enrollment Period has a limited window, and gaps in coverage can leave you exposed to unexpected medical costs. If you receive a termination notice, check immediately whether it was procedural or based on an actual eligibility determination, because the next steps are different for each.
How to Stay Prepared for Future Renewals
Redetermination isn’t a one-time event. Even after the post-pandemic unwinding is complete, your state will continue reviewing your eligibility on a regular cycle, usually every 12 months. A few practical steps can keep you from being caught off guard.
Update your address and phone number with your state Medicaid agency any time you move. Check your mail regularly for anything from your state’s health department or Medicaid office. If your state has an online Medicaid portal, create an account and monitor it for renewal notices and deadlines. Respond to every notice, even if you think your information hasn’t changed. Many states now offer online or phone-based renewal options that are faster than mailing a paper form. Open your renewal packet as soon as it arrives and note the deadline, because 30 days goes quickly.
