Mississippi Medicaid termination letters are landing in mailboxes again in 2026, continuing the post-pandemic redetermination process that began in 2023. Losing Mississippi Medicaid is terrifying, but federal law gives you a 90-day Special Enrollment Period to find replacement coverage through the ACA Marketplace at healthcare.gov. Three facts define your options: First, Mississippi has not expanded Medicaid under the ACA, which means traditional Mississippi Medicaid covers only very low-income children, pregnant women, people with disabilities, and very limited categories of adults. Second, the 90-day Medicaid Unwinding SEP is longer than the standard 60-day SEP you get for most other qualifying life events, giving you more time to compare plans and enroll. Third, Mississippi's non-expansion status creates a coverage gap for adults whose incomes fall below 100% of the Federal Poverty Level (about $15,960 for a single person in 2026). Those individuals do not qualify for ACA subsidies AND do not qualify for Mississippi Medicaid, leaving them in a gap that Congress has not yet closed nationally. If your income is above 100% FPL, ACA Marketplace subsidies are available and can make coverage affordable.
Federal rules for the Medicaid Unwinding SEP were established by CMS in 2023 and extended guidance through 2026. The qualifying life event is documented by the Mississippi Division of Medicaid (DOM) termination notice you receive by mail or through your Mississippi Medicaid online account at mississippi.gov. You must have this letter or documentation of your Medicaid coverage loss date before applying at healthcare.gov, because Marketplace agents and the federal portal will ask you to attest to the qualifying event. Mississippi Medicaid (administered by the Division of Medicaid under the Mississippi State Department of Health) remains the right first stop if your income might still qualify under legacy criteria: pregnant women qualify at higher income thresholds, children qualify for CHIP through Mississippi's program up to 209% FPL, and people with qualifying disabilities may qualify regardless of the Medicaid expansion status. Checking the ACA income limits before you enroll helps you calculate your premium tax credits for 2026 and avoid a surprise tax bill when you file in 2027.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most costly mistakes Mississippi residents make after losing Medicaid coverage:
- Assuming the standard 60-day SEP applies. Losing Medicaid triggers a 90-day Marketplace SEP under CMS Medicaid Unwinding rules, giving you 30 extra days compared to most other qualifying life events.
- Not appealing an administrative termination. Many Mississippi Medicaid terminations in 2026 are driven by address changes, undelivered mail, or paperwork errors. File an appeal within 90 days of the termination notice before accepting the loss as permanent.
- Thinking coverage gap adults have no options. Adults in Mississippi's coverage gap (income below 100% FPL, not qualifying for legacy Medicaid) can access free community health center care through HRSA-funded Federally Qualified Health Centers (FQHCs) statewide, often on a sliding-scale fee. They can also apply for emergency Medicaid for acute conditions.
- Forgetting to enroll children in CHIP separately. Children who lost Mississippi Medicaid coverage can enroll in CHIP year-round up to 209% FPL regardless of whether parents qualify for Marketplace plans. CHIP enrollment does not consume the SEP window.
- Estimating income too high or too low for subsidy calculations. ACA premium tax credits use projected 2026 Modified Adjusted Gross Income (MAGI). Underestimating income triggers a repayment on your 2026 tax return (Form 8962). Overestimating means you pay more in premiums than necessary all year. Use your most accurate estimate of current-year income.
- Missing the 90-day SEP window and waiting for November Open Enrollment. Open Enrollment for 2027 ACA coverage does not start until November 1, 2026. Missing your 90-day Medicaid Unwinding SEP leaves you uninsured for months with no coverage and no safety net for medical bills.
Mississippi's Coverage Gap: Who Falls Through the Cracks
Mississippi is one of 10 states that has not expanded Medicaid under the ACA. Traditional Mississippi Medicaid covers very narrow categories: children under 19 (through CHIP up to 209% FPL), pregnant women (up to 194% FPL), people receiving Supplemental Security Income (SSI), people with qualifying disabilities, and a small number of other categorical groups. Working-age adults without dependent children who do not meet disability criteria are generally ineligible for Mississippi Medicaid regardless of how low their income is.
Federal ACA subsidies for Marketplace plans are only available to people with incomes between 100% and 400% of the Federal Poverty Level (100% cliff) who are not offered affordable employer coverage. Adults below 100% FPL ($15,960 single, $33,000 family of 4 in 2026) cannot qualify for Marketplace premium tax credits and cannot qualify for Mississippi Medicaid expansion. This is the coverage gap. Federally Qualified Health Centers (FQHCs) operate across Mississippi on a sliding-fee scale and serve uninsured patients regardless of immigration status or income. Find an FQHC near you at findahealthcenter.hrsa.gov. Mississippi also has several free clinics and mission health programs through hospital charity care that can cover acute needs while you work toward longer-term coverage.
Documents You Need for the 90-Day Medicaid Unwinding SEP
Mississippi Medicaid termination letter: The official notice from the Division of Medicaid (DOM) stating your coverage end date. This is your proof of qualifying life event. Keep the original and make a copy. If you did not receive a termination letter but your coverage ended, call 1-800-421-2408 and request written confirmation of your coverage end date. Social Security numbers for all household members applying for coverage are required at healthcare.gov enrollment. Your most recent income documentation proves your projected 2026 household income for subsidy calculation: recent pay stubs, a self-employment income estimate, or an unemployment award letter all qualify. For Marketplace enrollment, also have your Mississippi address (ZIP code determines plan availability) and dates of birth for all dependents you are adding to the plan.
- Mississippi Medicaid termination letter from the Division of Medicaid (DOM) showing coverage end date
- Social Security numbers for all household members applying
- Proof of current income: pay stubs, unemployment award letter, or self-employment income estimate for 2026
- Mississippi ZIP code for plan availability lookup
- Birth certificates for dependents under 19 (if enrolling children in CHIP separately)
- Immigration documents (if applicable) for noncitizen household members
Mississippi Medicaid vs. ACA Marketplace: Which Pathway Is Right for You?
Mississippi Medicaid and the ACA Marketplace serve different populations and have different income rules. Mississippi Medicaid is free, has no monthly premium, covers comprehensive benefits, and is available year-round. The problem is eligibility: Mississippi Medicaid for adults is limited to people with qualifying disabilities, SSI recipients, and certain pregnant women. If you were enrolled in Mississippi Medicaid and lost it due to a redetermination (income review), it likely means the state determined your income or household situation changed and you no longer meet the strict categorical criteria.
ACA Marketplace plans through healthcare.gov are available to adults with incomes between 100% and 400% FPL in 2026 (between $15,960 and $63,840 for a household of 1, $33,000 and $132,000 for a household of 4). Premium tax credits can reduce monthly premiums dramatically: a 40-year-old in Mississippi with an income of $25,000 per year (about 157% FPL) typically pays under $100 per month for a Silver plan after credits in 2026. If you lost Medicaid and your income is now in that 100%-to-400% FPL range, the Marketplace is almost certainly your best path. Apply within your 90-day Medicaid Unwinding SEP window at healthcare.gov. Compare cost-sharing reduction (CSR) Silver plans first, as these offer the most comprehensive coverage for people in the 100%-250% FPL income range.
Mississippi Medicaid vs. ACA Marketplace comparison, 2026| Feature | Mississippi Medicaid | ACA Marketplace (with subsidy) |

Mississippi Medicaid Redetermination: Why Terminations Happen and How to Fight Back
Medicaid redetermination is the annual process by which states review whether enrolled individuals still meet eligibility requirements. During the COVID-19 public health emergency (2020-2023), states were prohibited from disenrolling people from Medicaid. Starting in April 2023, states resumed annual reviews. Mississippi has processed a large volume of redeterminations through 2026, with many terminations occurring due to administrative reasons rather than actual ineligibility. Common administrative causes include: Medicaid enrollment address not matching the current address, causing mail to be returned undelivered; the enrollee not responding to a redetermination form they never received; income data from state agency records appearing higher than it actually is; or the state's system unable to verify information through automated data matches.
Mississippi Medicaid enrollees who believe their termination was in error should request a fair hearing within 90 days of the termination notice. Fair hearing requests submitted within 10 days of the termination notice may result in continued coverage during the appeals process ('aid paid pending'). Submit written appeal requests to: Mississippi Division of Medicaid, 550 High Street, Suite 1000, Jackson, MS 39201. Alternatively, call 1-800-421-2408. Free legal assistance is available through Mississippi Center for Legal Services (1-800-498-1804) and Mississippi Volunteer Lawyers Project. The Mississippi NAACP and local legal aid offices have also organized assistance specifically for Medicaid redetermination appeals.
Frequently Asked Questions
How long do I have to enroll in new coverage after losing Mississippi Medicaid?
You have 90 days from your Mississippi Medicaid coverage end date to enroll in an ACA Marketplace plan through healthcare.gov. This 90-day Medicaid Unwinding Special Enrollment Period is longer than the standard 60-day SEP that applies to most other qualifying life events. The 90-day clock starts on your coverage termination date, not the date you received the termination letter. Mississippi Medicaid re-enrollment is available year-round for those who still meet categorical eligibility criteria, with no deadline.
What if my income is below 100% of the Federal Poverty Level in Mississippi?
Mississippi is one of 10 states that has not expanded Medicaid. Adults below 100% FPL ($15,960 for a single person in 2026) who do not meet Mississippi Medicaid's legacy categorical criteria (disability, pregnancy, SSI) face the coverage gap: they do not qualify for Mississippi Medicaid expansion AND cannot qualify for ACA Marketplace premium tax credits, because the ACA subsidy floor starts at 100% FPL. Options in the coverage gap include: Federally Qualified Health Centers (FQHCs) at findahealthcenter.hrsa.gov, which offer care on a sliding-fee scale; hospital charity care programs; and state-funded free clinics. Applying for SSI or disability benefits if you have a qualifying condition may open Medicaid eligibility.
Can I re-enroll in Mississippi Medicaid after losing it?
Mississippi Medicaid enrollment is year-round for those who meet eligibility criteria. If your termination was due to administrative reasons (address change, paperwork error, failure to return a redetermination form), you may be reinstated without penalty. Call the Mississippi Division of Medicaid at 1-800-421-2408 or visit mississippi.gov to start a redetermination. If you believe the termination was in error, file a written appeal within 90 days. Submit appeals to: Mississippi Division of Medicaid, 550 High Street, Suite 1000, Jackson, MS 39201. Free legal help is available from Mississippi Center for Legal Services at 1-800-498-1804.
Do my children automatically lose coverage when I lose Mississippi Medicaid?
Not necessarily. Children may have separate eligibility for Mississippi CHIP at incomes up to 209% FPL, which is approximately $63,480 for a family of 4 in 2026. CHIP enrollment is year-round and is separate from your Medicaid redetermination. If your children lost Medicaid at the same time as you, apply for CHIP immediately at mississippi.gov or call 1-800-421-2408. Children can enroll in CHIP without you needing to use your 90-day Marketplace SEP, and CHIP does not count against your SEP window.
What documents do I need to apply at healthcare.gov after losing Mississippi Medicaid?
You need four things to apply at healthcare.gov using the Medicaid Unwinding Special Enrollment Period: (1) Your Mississippi Medicaid termination letter from the Division of Medicaid showing your coverage end date (your proof of qualifying life event); (2) Social Security numbers for everyone applying; (3) Proof of your projected 2026 household income, such as pay stubs, an unemployment award letter, or a self-employment income estimate; (4) Your Mississippi ZIP code for plan availability lookup. Upload or attest to your termination documentation during the online application process. If you lost your termination letter, call 1-800-421-2408 to request a replacement.
What ACA Marketplace plans are available in Mississippi?
Mississippi uses the federal Marketplace at healthcare.gov. Plan availability varies by ZIP code and county. Mississippi has historically had limited insurer participation in some rural counties, so the number of plans available to you depends on your address. Silver plans with cost-sharing reductions (CSRs) are typically the best value for people between 100% and 250% FPL, as they reduce deductibles and out-of-pocket costs in addition to premium subsidies. For 2026, Mississippi Marketplace plans are offered by Ambetter from Magnolia Health, Cigna, and potentially other carriers depending on your county. Check healthcare.gov during your 90-day SEP window for exact plan options.
What happens if I miss the 90-day Mississippi Medicaid Unwinding SEP?
Missing your 90-day Medicaid Unwinding SEP means you lose the ability to enroll in an ACA Marketplace plan until the next Open Enrollment Period. ACA Open Enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027. During the gap, you would be uninsured unless you experience another qualifying life event (such as a birth, marriage, or move to a new state) that triggers a new 60-day SEP. Emergency Medicaid remains available for acute medical emergencies regardless of SEP status. If you missed the SEP due to circumstances beyond your control, contact a Marketplace navigator or call 1-800-318-2596 to ask about exceptional circumstances appeals.
How does losing Mississippi Medicaid affect my tax filing for 2026?
If you enroll in an ACA Marketplace plan through healthcare.gov after losing Mississippi Medicaid, you will receive a 1095-A tax form in January 2027 showing the premium tax credits applied to your monthly premiums. File Form 8962 with your 2026 federal tax return to reconcile those credits against your actual 2026 Modified Adjusted Gross Income (MAGI). If your actual 2026 income was higher than what you estimated when enrolling, you may owe back some credits. If your income was lower, you receive an additional refund. Medicaid coverage itself (while you had it) does not generate a 1095-A; you may receive a 1095-B from the Mississippi Division of Medicaid confirming the months you were enrolled.
