Coverage Transitions
Losing Medicaid? How to Transition to ACA Marketplace Coverage Without a Gap
Millions of Americans have lost Medicaid coverage since the pandemic unwinding began. If you're one of them, you likely qualify for affordable ACA marketplace coverage with subsidies — here's exactly how to make the switch without a gap in protection.
The Medicaid Unwinding: Why Millions Lost Coverage
During the COVID-19 pandemic, the federal government enacted a continuous enrollment provision that prevented states from removing anyone from Medicaid rolls. This protection kept millions covered regardless of whether their circumstances changed — a critical lifeline during an unprecedented health crisis.
When the continuous enrollment requirement ended in April 2023, states began the massive process of redetermining eligibility for every Medicaid enrollee. This process — known as the Medicaid unwinding — has resulted in over 25 million people being disenrolled from the program as of early 2025.
Here's the critical detail: a significant portion of those disenrollments were procedural, not because people were actually ineligible. Many lost coverage simply because they didn't receive the renewal paperwork, didn't respond in time, or had an outdated address on file. If this happened to you, you may still be eligible for Medicaid — and you should absolutely appeal (more on that below).
⚠️ Important
If you were disenrolled from Medicaid for procedural reasons (like not returning paperwork), contact your state Medicaid office immediately. You may be able to get reinstated without any gap in coverage. Many states are reopening cases that were improperly closed.
Your Special Enrollment Period: The 60-Day Window
Losing Medicaid coverage qualifies you for a Special Enrollment Period (SEP) on the ACA marketplace. This means you don't have to wait for the annual Open Enrollment Period (typically November through mid-January) — you can sign up for a marketplace plan right away.
Here's how the timeline works:
60 Days Before
If you know your Medicaid is ending on a specific date, you can start shopping for marketplace plans up to 60 days before your coverage terminates. This is the ideal scenario — apply early and have your new plan ready to go.
60 Days After
If you've already lost Medicaid, you have 60 days from your coverage end date to enroll in a marketplace plan. Don't wait until the last minute — the sooner you apply, the sooner your new coverage begins.
Coverage Start Date
When you select a plan during your SEP, coverage typically starts on the first day of the month following your plan selection. For example, if you choose a plan on March 15, your coverage would begin April 1.
💡 Pro Tip
When applying on HealthCare.gov, select "loss of other coverage" as your qualifying life event and specify that you lost Medicaid or CHIP. You'll need your Medicaid termination notice as proof.
Step-by-Step: How to Apply on HealthCare.gov
The enrollment process is more straightforward than most people expect. Here's exactly what to do:
Gather Your Documents
You'll need your Medicaid termination notice, Social Security numbers for everyone in your household, proof of income (recent pay stubs, tax returns, or employer letters), and immigration documents if applicable.
Create or Log Into Your HealthCare.gov Account
Visit HealthCare.gov (or your state's exchange if your state runs its own marketplace). If you already have an account from a previous enrollment, log in with your existing credentials.
Report Your Life Change
Select "loss of health coverage" as your qualifying event and indicate that you lost Medicaid/CHIP. Enter the date your Medicaid coverage ended (or will end). This triggers your 60-day Special Enrollment Period.
Complete Your Application
Enter your household size, income, and other details. The system will calculate your eligibility for premium tax credits (subsidies) and cost-sharing reductions. Be as accurate as possible with your income — this directly determines your monthly costs.
Compare Plans and Enroll
Browse available plans in your area, comparing premiums, deductibles, copays, and provider networks. Pay your first month's premium to activate coverage. Your plan starts the first of the following month.

One of the biggest concerns for people leaving Medicaid is cost. The good news: if your income is between 100% and 400% of the Federal Poverty Level (FPL), you almost certainly qualify for premium tax credits that significantly reduce your monthly premiums.
For 2025, here's what that income range looks like:
| Household Size | 100% FPL | 250% FPL | 400% FPL |
|---|---|---|---|
| 1 person | $15,060 | $37,650 | $60,240 |
| 2 people | $20,440 | $51,100 | $81,760 |
| Family of 4 | $31,200 | $78,000 | $124,800 |
Many former Medicaid enrollees have incomes just above the Medicaid threshold — typically between 138% and 200% FPL. At these income levels, subsidies are extremely generous. A single person earning $20,000 per year, for instance, might pay as little as $20–$50 per month for a Silver plan after subsidies.
In addition to premium tax credits, people with incomes below 250% FPL qualify for cost-sharing reductions (CSRs) when they choose a Silver-tier plan. CSRs lower your deductible, copays, and out-of-pocket maximum — making a Silver plan function more like a Gold or Platinum plan at a fraction of the cost.
Use our ACA Subsidy Calculator to get a personalized estimate of your premium tax credits based on your household size and income. You can also check the income guidelines page to understand exactly where you fall on the FPL scale.
💡 Silver Plan Strategy
If your income is below 250% FPL, always choose a Silver plan. It's the only tier that qualifies for cost-sharing reductions, which can save you thousands in out-of-pocket costs. Read more about the ACA subsidy cliff to understand how income affects your benefits.
Choosing the Right Marketplace Plan After Medicaid
Coming from Medicaid — which typically has zero or very low cost-sharing — marketplace plan costs can feel like sticker shock. Here's how to choose wisely:
Check if Your Doctors Are In-Network
Before choosing a plan, verify that your current doctors, specialists, and preferred hospital are in the plan's provider network. This is especially important if you're in the middle of treatment or managing a chronic condition. Most marketplace plans have a provider search tool on their website.
Review Your Prescription Drug Coverage
Check each plan's formulary (drug list) to make sure your medications are covered and at what tier. Some plans may require prior authorization or step therapy for certain drugs. If you take expensive medications, this can be the single biggest cost factor in your plan choice.
Understand the Metal Tiers
Marketplace plans come in four metal tiers: Bronze (lowest premium, highest out-of-pocket), Silver, Gold, and Platinum (highest premium, lowest out-of-pocket). For most people transitioning from Medicaid, Silver is the best choice because it's the only tier eligible for cost-sharing reductions.
Compare Total Costs, Not Just Premiums
A plan with a $0 premium might have a $9,000 deductible — meaning you'd pay thousands out of pocket before insurance kicks in. Look at the total picture: premiums + deductible + copays + coinsurance. Our plan comparison calculator can help you evaluate total costs.
How to Avoid a Coverage Gap
A gap in health insurance coverage can be financially devastating if you need medical care during that window. Here's how to minimize or eliminate any gap:
✅ Act on Your Termination Notice Immediately
As soon as you receive notice that your Medicaid is ending, start your marketplace application. Don't wait for your coverage to actually lapse — you can apply up to 60 days before your end date.
✅ Pay Your First Premium Promptly
Your marketplace coverage doesn't begin until you pay the first month's premium. After selecting a plan, you'll receive a bill from the insurance company. Pay it immediately — delays here are the most common cause of coverage gaps.
✅ Appeal and Apply Simultaneously
If you believe your Medicaid termination was incorrect, you can appeal the decision with your state Medicaid office while also applying for marketplace coverage. If Medicaid is reinstated, you can cancel the marketplace plan. This dual-track approach ensures you're never uninsured.
✅ Ask About Transitional Coverage
Some states offer transitional Medicaid benefits or extended coverage during the switch. Contact your state's Medicaid office or marketplace call center to ask about bridge coverage options specific to your state.
State-Specific Considerations
The transition from Medicaid to marketplace coverage varies significantly by state. Here are the key differences to be aware of:
Medicaid Expansion vs. Non-Expansion States
In the 40 states (plus DC) that expanded Medicaid, adults are eligible up to 138% FPL. In the 10 states that haven't expanded, eligibility thresholds are much lower — sometimes as low as 17% FPL for parents and zero for childless adults. If you're in a non-expansion state and earn too much for Medicaid but less than 100% FPL, you may fall into the "coverage gap" where you don't qualify for either Medicaid or marketplace subsidies.
State-Based Exchanges
Eighteen states and DC run their own marketplaces instead of using HealthCare.gov. States like California (Covered California), New York (NY State of Health), and Massachusetts (Health Connector) have their own enrollment websites and may offer additional benefits or extended enrollment periods for Medicaid transitions.
Children's Coverage (CHIP)
If your children were on Medicaid or CHIP and lost coverage, they may still be eligible for CHIP even if you aren't eligible for Medicaid. CHIP income limits are typically higher than adult Medicaid limits. Check your state's CHIP program before enrolling children in a marketplace plan — CHIP coverage is usually more comprehensive and less expensive.

What If You're Also Dealing with Job Loss?
If you lost Medicaid because your income increased (for example, from getting a new job), your employer may offer health insurance. Here's what to consider:
- Employer coverage vs. marketplace: If your employer offers affordable coverage (less than about 9.02% of your household income for employee-only coverage), you generally won't qualify for marketplace subsidies.
- Waiting periods: Many employers have a 60-90 day waiting period before benefits begin. You can use a marketplace plan as bridge coverage during this gap.
- COBRA considerations: If you're leaving a previous job, COBRA lets you continue your old employer plan — but it's typically much more expensive than a subsidized marketplace plan.

Common Mistakes to Avoid
❌ Assuming You Can't Afford Marketplace Coverage
Many former Medicaid enrollees assume marketplace plans are unaffordable without checking their subsidy eligibility. With enhanced subsidies still in effect, many people qualify for plans under $50/month. Always check before assuming.
❌ Missing the 60-Day Window
Your Special Enrollment Period is time-limited. If you miss the 60-day window, you'll have to wait until the next Open Enrollment Period (starting in November) to get coverage — potentially leaving you uninsured for months.
❌ Choosing Bronze When Silver Is Better
A $0-premium Bronze plan is tempting, but if your income qualifies you for cost-sharing reductions, a Silver plan will almost always save you more money overall. The lower deductibles and copays on an enhanced Silver plan can save thousands per year.
❌ Not Reporting Income Accurately
Underestimating your income to get a larger subsidy can result in a tax bill when you file your return. Overestimating means you leave subsidy money on the table. Use your best realistic estimate, and update it on the marketplace if your income changes.
