I missed open enrollment: can I still get health insurance?

Reviewed by Howard Yeh, agency principal, Healthcare.com Insurance ServicesLast reviewed 2026-09-04

Yes, you may still be able to get health insurance outside of open enrollment. If you have experienced a qualifying life event, such as losing your health coverage, moving to a new area, getting married, or having a baby, you generally have 60 days to enroll in a Marketplace health plan through a special enrollment period (SEP). Not every situation qualifies, but many common life changes do.

At a glance

  • A special enrollment period lets you sign up for health insurance outside the regular open enrollment window.
  • You typically have 60 days from your qualifying life event to enroll.
  • Medicaid and the Children's Health Insurance Program (CHIP) accept applications year-round, regardless of enrollment periods.

What counts as a qualifying life event

Qualifying life events are specific changes in your circumstances that open a window to enroll. The most common ones include:

  • Losing health coverage. This includes losing job-based insurance, aging off a parent's plan at 26, losing Medicaid or CHIP eligibility, or having a plan cancel. The key requirement is that the loss of coverage was not voluntary.
  • Moving to a new area. If you move to a ZIP code or county where different health plans are available, you may qualify. This generally applies to permanent moves, not temporary travel, and you generally must have had qualifying coverage for at least one day during the 60 days before your move.
  • Changes in household. Getting married, having a baby, adopting a child, or placing a child for foster care.
  • Changes in income. Gaining or losing eligibility for premium tax credits or Medicaid because your estimated income changed.
  • Other life changes. Becoming a U.S. citizen, leaving incarceration, gaining membership in a federally recognized tribe, or being affected by certain errors in Marketplace enrollment.

This list covers the most common situations, but it is not exhaustive. The Marketplace evaluates each case individually.

What generally does not qualify

Not every change in your life opens a special enrollment period. These situations typically do not trigger an SEP:

  • Voluntarily dropping your coverage. If you chose to cancel your plan or simply let it lapse, that generally does not count as a qualifying event.
  • Missing open enrollment without a qualifying reason. Forgetting to sign up or deciding not to enroll during open enrollment does not create a new enrollment window on its own.
  • Dissatisfaction with your current plan. Wanting a different plan, a lower premium, or a different network is not a qualifying life event.

If you are unsure whether your situation qualifies, it is worth submitting a Marketplace application. The Marketplace will review the circumstances and let you know.

The 60-day enrollment window

For most qualifying life events, you have 60 days to select and enroll in a plan. The clock typically starts on the date of the event itself, such as the date your prior coverage ended, the date you moved, or the date of your marriage.

A few things to keep in mind:

  • Loss of coverage. You may be able to start your application up to 60 days before your coverage ends, or up to 60 days after it ends. Planning ahead can prevent a gap.
  • Birth or adoption. The 60-day window starts on the date of the birth, adoption, or placement.
  • Moving. The window starts on the date of your move to the new coverage area.

If you miss the 60-day window, you would generally need to wait until the next open enrollment period unless another qualifying event occurs.

When your coverage starts

Your coverage effective date depends on when you select your plan and which qualifying event you experienced:

  • For most SEPs: Coverage generally starts the first day of the month after you pick a plan, no matter which day of the month you enroll.
  • For birth, adoption, or placement: Coverage can be backdated to the date of the event, so your newborn or newly adopted child is covered from day one.
  • For loss of coverage: You may be able to align your new coverage start date to avoid or minimize a gap.

These are general guidelines. Your actual effective date may vary based on your state and the specific circumstances of your enrollment.

Documentation you may need

When you apply for a special enrollment period, the Marketplace may ask you to verify your qualifying event. Common documents include:

  • A letter from your previous insurer or employer showing your coverage end date
  • A lease, mortgage document, or utility bill showing your new address
  • A marriage certificate
  • A birth certificate or adoption order
  • Proof of prior coverage (for loss-of-coverage SEPs)

Starting with plan year 2027, HealthCare.gov generally verifies special enrollment period eligibility before coverage starts, so expect to be asked for proof of your qualifying event. Having documents ready can speed up the process and avoid delays in getting covered.

Medicaid and CHIP are available year-round

If your income is below certain levels or you have children who may qualify, Medicaid and the Children's Health Insurance Program (CHIP) accept applications at any time, regardless of open enrollment. There is no special enrollment period required, and there is no 60-day deadline.

Eligibility for Medicaid varies by state. When you submit a Marketplace application, the system checks whether you or your family members may qualify for Medicaid or CHIP automatically.

State-by-state variations

Some states that run their own health insurance marketplaces have additional enrollment opportunities or broader qualifying events. For example, certain states have extended enrollment periods, or they recognize qualifying events that the federal Marketplace does not.

If your state operates its own marketplace (such as Covered California, NY State of Health, or others), check with your state exchange directly. The rules may be slightly different from the federal HealthCare.gov guidelines.

What to do next

Primary action: Check if you qualify for a special enrollment period by answering a few questions about your situation. If you are eligible, you can compare plans and enroll right away.

Alternative: If you are not sure whether your situation qualifies, call or chat with a licensed agent at Healthcare.com who can walk you through your options at no extra cost.

This is a solicitation for insurance. HealthCare.com is a non-government website operated by HealthCare.com Insurance Services, LLC, a licensed health insurance agency. Depending on your selections, we may present health and Medicare-related insurance products, including Affordable Care Act (ACA) plans, short-term medical insurance, indemnity and other supplemental insurance, dental and vision plans, and Medicare plans, as well as information about health savings accounts (HSAs). Qualified ACA plans must meet or exceed the essential health benefit requirements of the Affordable Care Act. Non-ACA plans, including short-term medical and indemnity plans, are not required to cover all essential health benefits, are not comprehensive health coverage, and are not available in all states. Pre-existing condition provisions, benefits, limitations, and exclusions vary by plan type and state. Review all plan details and product brochures before you buy.

Open Enrollment for 2027 ACA coverage on HealthCare.gov runs November 1, 2026 through January 15, 2027. Enroll by December 15, 2026 for coverage starting January 1, 2027. Dates vary in states that run their own marketplace. To enroll in ACA coverage outside Open Enrollment, you must qualify for a Special Enrollment Period.

Eligibility for Affordable Care Act (ACA) premium tax credits and cost-sharing reductions is based on household income, household size, and plan availability in your area. The enhanced premium tax credits that were in effect from 2021 through 2025 expired on December 31, 2025. For plan year 2027, premium tax credits follow the standard rules under Internal Revenue Code §36B, which generally limit eligibility to households with income between 100% and 400% of the federal poverty level. Under these rules, eligible households are expected to contribute between 2.15% and 10.22% of household income toward the cost of a benchmark silver plan (IRS Rev. Proc. 2026-26). Premiums, plan availability, and subsidy amounts vary by income, household size, age, and location. Final eligibility and premium tax credit amounts are determined by the Health Insurance Marketplace. If your actual income differs from your estimate, you may have to repay some or all of any advance premium tax credit when you file your taxes. Federal legislation affecting premium tax credits may change these amounts.
