How to Get Health Insurance After Losing Medicaid in 2026: Your 90-Day Special Enrollment Window Explained

For more than three years, states have been working through the long tail of Medicaid "unwinding" — the post-pandemic redetermination process that pushed millions of people out of Medicaid because their income had risen, their state's eligibility rules changed, or they simply missed a renewal letter. By mid-2026, the formal unwinding period is over, but the underlying machinery has not stopped. Every state still reviews Medicaid eligibility at least once a year, and the Centers for Medicare & Medicaid Services (CMS) is enforcing tighter compliance with renewal requirements through the end of the year. The result: tens of thousands of households still receive a Medicaid termination letter every month — and many do not know that a generous, 2026-specific safety net is waiting for them on the Marketplace.

If you just lost Medicaid or CHIP, you have a 90-day window — longer than the standard 60-day Special Enrollment Period for other loss-of-coverage events — to enroll in a Marketplace plan with subsidies. For most former Medicaid enrollees, the resulting premium is small or even zero. This guide walks through the exact steps, the paperwork that triggers each option, the income math that determines what you'll pay, and the moves that prevent a coverage gap.

Medicaid termination letters look administrative, but every paragraph matters. Two pieces of information determine everything that follows:

• The reason for termination. This will be either substantive ("your income exceeds the eligibility limit") or procedural ("we did not receive your renewal form" / "mail was returned"). The reason controls whether reinstatement is possible.
• The effective date. The day your coverage officially ends — not the day the letter was mailed. Your 90-day Marketplace SEP runs from this date.

If the reason is procedural, you almost always have a parallel deadline (typically 90 days in most states) to submit the missing paperwork and have Medicaid reinstated retroactively, without restarting the application. If the reason is substantive, the Marketplace is your next stop.

The Special Enrollment Period after Medicaid or CHIP loss is 90 days from the date your coverage ends. This is a permanent rule that HHS finalized in 2024 and that remains in effect for 2026, in contrast to the standard 60-day window that applies to most other qualifying life events such as moving, marriage, or losing employer coverage.

Within the 90 days, you can:

• Enroll in any Marketplace plan (Bronze, Silver, Gold, Platinum, or Catastrophic depending on age and exemption).
• Receive Premium Tax Credits and (for Silver plans) Cost-Sharing Reduction benefits based on your projected 2026 MAGI.
• Add dependents who lost coverage with you.
• Choose a coverage start date of the first day of the month after enrollment, or — at most state exchanges — an earlier retroactive date if you have documented good cause.

If you miss the 90 days, your only remaining paths are the regular open enrollment period for the following plan year (November 1 to December 31, 2026 for 2027 coverage), a different qualifying life event, year-round Medicaid re-application if your circumstances change, or a non-ACA option such as a short-term plan or a state Basic Health Program if your state runs one.

The single biggest reason former Medicaid enrollees end up uninsured after a termination is sticker shock — the unsubsidized Silver premium looks unaffordable, and they walk away without realizing that subsidies will cover most of it. For households whose income just crossed the Medicaid threshold, the Premium Tax Credit is at its largest.

Federal Poverty Level (FPL) reference points for 2026:

If you just lost Medicaid because of a modest income increase, your MAGI is almost certainly between 138% and 200% of FPL. At that income, the benchmark Silver plan typically costs between $0 and $80 per month after the Premium Tax Credit — and Cost-Sharing Reductions on the Silver plan turn a $5,000 deductible into a $500–$1,000 deductible automatically. Below 250% FPL, the CSR benefits are still meaningful; above 250% FPL they phase out entirely.

For households moving from Medicaid, the most common mistake is choosing the cheapest sticker-price plan (often Bronze) without realizing how much CSR benefits on a Silver plan are worth. A side-by-side at 175% FPL typically looks like this:

For anyone with a chronic condition, expecting children, or facing planned procedures, the Silver CSR plan is almost always the best value at this income — Bronze looks free until you hit the deductible. For households that rarely use care and want HSA access, the 2026 rule change is meaningful: starting January 1, 2026, all Bronze and Catastrophic Marketplace plans are now HSA-eligible high-deductible plans. That makes the Bronze tier a more flexible savings vehicle than it has been in past years.

The 90-day window protects your enrollment rights, but it does not automatically give you continuous coverage. Whether you have a gap depends on when you enroll relative to when your Medicaid ends.

1. Enroll before your Medicaid termination date. If you submit your Marketplace application and select a plan before your Medicaid ends, you can usually have coverage start the first day of the month after Medicaid stops — no gap.
2. Enroll within the same calendar month. If you complete enrollment by the last day of the month in which Medicaid ends, you may be able to backdate the Marketplace start to the day after Medicaid stopped at some state exchanges.
3. Enroll after the month ends. If you wait into the next month, your Marketplace coverage typically starts the first day of the month after enrollment. That can mean a 30- to 60-day gap. Use a same-day care option (community health center sliding-scale, telehealth) for urgent needs.

If you have an ongoing prescription, ask your pharmacist for a 90-day fill before your Medicaid ends. Most generics under the GoodRx-style cash price are cheaper than a one-time fill at uninsured retail. Save the receipt — if you reinstate Medicaid retroactively, you can submit the receipt for reimbursement in most states.

Scenario 1: The Procedural Termination

Marcus, 34, missed a renewal form because his address had changed. His state ended Medicaid effective April 30, 2026, and mailed the notice to his old apartment. He found out on May 8 when his prescription was denied at the pharmacy. He filed a reconsideration with the state Medicaid office on May 10 and was reinstated retroactively to May 1 within nine days. Because he acted within his state's 90-day reconsideration window, he never lost coverage on paper. He kept the Marketplace SEP in reserve in case the reconsideration had been denied.

Scenario 2: The Income Increase

Aisha, 41, started a full-time job in February 2026 that pushed her annual household income from $19,000 to $36,000 — well above her state's Medicaid threshold of about $26,000 for a household of two. Her Medicaid ended March 31. She enrolled in a Marketplace Silver plan on April 6 with a May 1 start date. At roughly 167% FPL she received a Premium Tax Credit that brought her benchmark Silver premium down to $32 per month, and her CSR (94%) variant gave her a $250 deductible and $2,000 out-of-pocket maximum. The 30-day gap in April was covered by her old prescription stockpile and one no-cost visit at a federally qualified health center.

Scenario 3: The Family with Mixed Eligibility

The Patel family — two parents, two children — had all four on Medicaid until the parents' income rose above the family threshold. The children remained CHIP-eligible at the higher income, but the parents lost coverage. They enrolled the two adults in a Marketplace Silver plan during the 90-day SEP and kept the children on CHIP. Total Marketplace premium for the parents after PTC: about $140 per month. The family used our Plan Cost Calculator to confirm the split was cheaper than enrolling the whole family on the Marketplace.

Have these ready before you start the Marketplace application. Most enrollments stall on missing documents, not eligibility:

• The Medicaid termination notice (PDF, screenshot, or photo of the paper letter).
• Most recent pay stubs or self-employment income records covering the last 30 days.
• Your most recently filed federal tax return (1040), or a written statement of expected 2026 income if your situation has changed materially.
• Social Security numbers for everyone in the household.
• Documentation of any deductions you plan to claim (HSA, traditional IRA, student loan interest) — these reduce MAGI and increase your subsidy.
• The names of doctors and prescriptions you need covered, so you can check plan networks and formularies before choosing.

If you are self-employed or have variable income, project conservatively. Underestimating MAGI is what triggers subsidy clawback at tax time — see our companion guide on avoiding ACA subsidy repayment for the specific moves that protect against a year-end surprise.

If your Medicaid ended more than 90 days ago and you did not enroll in a Marketplace plan, you still have options. None are as cheap as the Marketplace with subsidies would have been, but every one of them beats going uninsured.

1. Re-apply for Medicaid. If your income has dropped again or your household has changed, you can re-apply at any time. Coverage in most states is retroactive up to 90 days before the application.
2. Check for a different qualifying life event. Marriage, having a baby, moving, or losing other coverage all reset the SEP clock with a new 60-day window.
3. Open a short-term limited-duration plan. These are not ACA-compliant and typically exclude pre-existing conditions, but they prevent catastrophic exposure. Buyer beware — read the exclusions carefully.
4. Use a federally qualified health center (FQHC). FQHCs charge on a sliding scale based on income, regardless of insurance status. For most former Medicaid enrollees, FQHC visits cost between $0 and $35.
5. Wait for open enrollment. Open enrollment for 2027 coverage runs November 1 to December 31, 2026. This year the window is shorter than in previous years — do not assume January enrollment will be available.

If you just received a Medicaid termination letter, work this checklist today:

1. Read the letter for the termination reason and effective date.
2. If procedural → file a reconsideration with the state Medicaid office within the deadline (usually 90 days).
3. If substantive or reconsideration unlikely → start a Marketplace application immediately at HealthCare.gov or your state exchange.
4. Project 2026 MAGI honestly. Include all income sources and any deductions you reasonably expect to claim.
5. Compare metal tiers using the actual numbers — not the sticker premium. Silver CSR is almost always the best value below 250% FPL.
6. Pick a start date that minimizes any coverage gap (ideally the first day of the month after Medicaid ends).
7. Save documentation of your Medicaid termination, income, and Marketplace selection. The Marketplace may request verification within 90 days of enrollment.

Most former Medicaid enrollees end up paying less than $80 per month for a Silver CSR plan that, on net, costs them less out of pocket than Medicaid did when factoring in covered services. The single biggest mistake is not enrolling at all — and that mistake usually happens because the person never realized the 90-day SEP existed.
