Can You Get Health Insurance After Open Enrollment Ends?

1. Your five mid-year enrollment paths

Once Open Enrollment closes, the ACA Marketplace becomes restricted — but coverage is still very much available if you understand the routes. Here’s the complete map:

The first option — SEP via qualifying event — is the one most people overlook. Roughly 40% of mid-year applicants qualify for an SEP they didn’t realize they were eligible for. The next sections walk through each path in detail.

2. Special Enrollment Period qualifying events

A Special Enrollment Period gives you a 60-day window to enroll in ACA Marketplace coverage after a qualifying life event. Each event has a specific definition and documentation requirement.

Loss of qualifying coverage

• Job loss (laid off, fired, quit) — loss of employer-sponsored coverage
• Loss of COBRA when your maximum coverage period ends (typically 18 months)
• Aging off a parent’s plan at age 26
• Spouse loses job and you were a dependent on their plan
• Reduction in work hours below your employer’s benefits threshold
• Loss of Medicaid or CHIP (e.g., redetermination found you ineligible)
• Death of a policyholder you were covered under
• Divorce or legal separation that ends your coverage as a dependent

Changes in household composition

• Marriage — one spouse must have had qualifying coverage in the prior 60 days
• Birth or adoption of a child — coverage retroactive to date of birth/placement
• Divorce if it results in loss of coverage
• Death of a household member

Changes in residence

• Permanent move to a new ZIP code where different plans are available
• Move to/from a shelter or transitional housing
• Seasonal workers moving for the season
• Students moving to or from school
• Release from incarceration

Other qualifying changes

• Becoming a U.S. citizen or gaining lawful immigration status
• Membership in a federally recognized tribe (year-round enrollment, monthly opportunities)
• Income change that makes you newly eligible for or ineligible for subsidies (in some cases)
• Marketplace error or misconduct that prevented prior enrollment
• Exceptional circumstances (natural disaster, serious medical condition, etc.)

3. How to apply during an SEP

Once you have a qualifying event, the process is:

1. Confirm your event date. The 60-day clock starts on the date of the qualifying event (or the date of coverage loss, for loss-of-coverage events).
2. Go to Healthcare.gov (or your state Marketplace) and start a new application. Select “I had a life change recently” when prompted.
3. Choose your event type from the dropdown. The application will adjust the questions based on your event.
4. Submit documentation proving the event — termination letter, marriage certificate, birth certificate, lease, etc. The Marketplace verifies most events before activating coverage.
5. Compare plans and enroll. Once verified (usually within 7–14 days), you can browse plans and select coverage.
6. Coverage start date depends on event type: most SEPs follow the “1st of the next month” rule, but birth/adoption SEPs are retroactive to the event date, and loss-of-coverage SEPs can be retroactive to avoid a gap.

4. Medicaid: year-round enrollment

Medicaid has no enrollment window. If your income drops below your state’s threshold — or you experience a life change that newly qualifies you — you can apply any day of the year. Coverage typically starts the 1st of the month you apply (some states allow retroactive coverage up to 3 months back).

2026 Medicaid eligibility (expansion states)

In the 41 states (plus DC) that expanded Medicaid under the ACA, the threshold is 138% of the Federal Poverty Level:

• Single: $20,782/year ($1,732/month)
• Family of 2: $28,207/year
• Family of 3: $35,632/year
• Family of 4: $43,056/year

Non-expansion states (10 as of 2026)

TX, FL, GA, TN, MS, AL, SC, KS, WY, WI did not expand. In these states, Medicaid is restricted to specific populations (parents of minor kids, pregnant women, people with disabilities, seniors). Adults without dependents and incomes below ~$15,000 fall into the “coverage gap” — too low for ACA subsidies, too high for state Medicaid. There’s no easy fix for the gap; your best options are short-term medical or waiting for next OEP.

5. Short-term medical as bridge coverage

Short-term medical (STM) plans are non-ACA insurance products designed to fill gaps between major coverage. They’re available year-round with no enrollment window, often with same-day or next-day coverage start.

When STM is useful after missed OEP

• You’re young, healthy, and need catastrophic coverage
• You expect to qualify for an SEP soon (waiting for a marriage, a move, etc.)
• You missed OEP and the next one isn’t until November
• You need coverage to start before the 1st of next month

STM limitations to understand

• Pre-existing conditions excluded — STM is medically underwritten. Anything you’ve been diagnosed with or treated for in the past 5 years is typically not covered.
• No essential health benefits requirement — maternity care, mental health, prescription drugs may be limited.
• Plan duration varies by state — some states cap STM at 3-6 months; others allow up to 36 months with renewals.
• Not minimum essential coverage in California, Massachusetts, New Jersey, Rhode Island, DC, or Vermont (state-level mandates apply).
• Lifetime caps and per-illness maximums can leave you exposed on a major claim.

Cost typically $80–$300/month depending on age, health, and state. More on short-term medical →

6. Year-round PPO plans

Beyond ACA Marketplace, some carriers (Cigna, UnitedHealthcare, Golden Rule, First Health Network) offer PPO health insurance plans available year-round with broader provider networks than typical Marketplace plans. These are non-ACA, medically underwritten plans — meaning your application can be declined or surcharged based on health history — but they don’t have an enrollment window.

PPO year-round plans are useful for:

• Healthy individuals who need a national PPO network for travel/multiple-state work
• People who need access to specific specialists outside ACA networks
• High earners who can’t qualify for ACA subsidies and want more network flexibility
• Self-employed people whose income fluctuates and want predictable coverage

These plans are not for everyone — they cost more than subsidized ACA in most cases, and they don’t cover pre-existing conditions on the same terms as ACA plans. But for the right profile (healthy, network-focused, mid-to-high income), they’re a legitimate year-round option.

7. What you CAN’T do after Open Enrollment

Some myths to clear up about post-OEP enrollment:

You can’t enroll in ACA Marketplace without an SEP or Medicaid eligibility

Even if you’re willing to pay full price (no subsidies), the standard ACA application is closed outside OEP and SEP windows. There’s no “open application for full-price ACA” option. This isn’t a financial barrier — it’s a regulatory one.

You can’t use STM as a permanent replacement

STM is structured for short-term coverage by design. Continuous STM enrollment year after year leaves you exposed: pre-existing conditions accumulate, lifetime caps apply, and any major diagnosis will likely be excluded from subsequent renewals.

You can’t backdate enrollment beyond the rules

Even with an SEP, coverage start dates follow specific rules. Most SEPs activate coverage on the 1st of the month after enrollment, not retroactively. Exceptions: birth/adoption (retroactive to event), loss-of-coverage SEPs (can sometimes be retroactive to prevent a gap). You can’t just say “make my coverage start March 1st” if you’re enrolling in May.

“No penalty” doesn’t mean “no enrollment rules”

The federal individual mandate penalty was reduced to $0 in 2019, but enrollment rules still exist. Several states (CA, MA, NJ, RI, DC, VT) have their own mandates with penalties. And the federal rules around when you can enroll didn’t change — only the tax penalty for being uninsured.

8. Strategic timing for the rest of the year

If you missed OEP and have no SEP today

Three plays:

1. Check Medicaid eligibility right now. A surprising number of people qualify and don’t realize it. No window, no waiting.
2. STM as bridge coverage. Buy 6–12 months of catastrophic protection while you wait for next OEP or watch for an SEP.
3. Mark your calendar for November 1, 2026. Next OEP opens for 2027 coverage. Enroll by Dec 15 for January 1 coverage; by Jan 15 for February 1 coverage.

If you’re approaching an SEP-triggering event

Examples: planning a wedding, due to give birth, moving, expecting to lose employer coverage. You can typically enroll up to 60 days BEFORE the event. This is the right move — submit your application early so coverage activates the moment the event happens.

If you’ve had a life event in the past 60 days and didn’t act

Apply immediately. The 60-day SEP window is strict — once it closes, you’re back to the no-window state until next OEP.
