Special Enrollment Periods: Which Life Events Qualify and How Long You Have
If you miss Open Enrollment, you are not always out of options. A Special Enrollment Period (SEP) is a limited window that lets you enroll in or change a Marketplace plan after certain life events. This guide covers the events that commonly qualify and how timing works.
What Is a Special Enrollment Period?
An SEP is triggered by a qualifying life event rather than by the calendar. Each event has its own rules, and the Marketplace may ask you to confirm the event with documents. Because eligibility rules have changed in recent years, always check the current list on HealthCare.gov or your state Marketplace.
Life Events That Commonly Qualify
Losing other health coverage. Losing job-based coverage, aging off a parent's plan at 26, or losing Medicaid or CHIP eligibility can open an SEP. Voluntarily canceling coverage or missing a premium payment usually does not.
Changes in household. Getting married, getting divorced and losing coverage, having a baby, or adopting a child may qualify.
Moving. A move to a new ZIP code or county that changes which plans are available to you can qualify, particularly if you had qualifying coverage before the move.
Other situations. Certain changes in citizenship or immigration status, release from incarceration, and some exceptional circumstances can also qualify.
How Long Do You Have to Enroll?
For many events, the window is typically 60 days. For loss of coverage, you may be able to apply up to 60 days before the loss and up to 60 days after. When coverage starts depends on the event and when you choose a plan, which is why acting early matters. If you wait until the end of the window, coverage may start later than you expect.
Documents You May Need
The Marketplace may ask you to upload proof of the event. Examples include a letter from your former insurer showing the date coverage ended, a marriage certificate, a birth record, or a lease or utility bill showing your new address. Having these ready can prevent delays.
What If Your Situation Is Not on the List?
Some situations fall in a gray area. If you are unsure, check your state Marketplace rules or ask a licensed agent whether your situation might qualify. Eligibility is decided by the Marketplace, not by an agent.
Enrolling During Open Enrollment Instead
If your event happens close to Open Enrollment, you may have more than one way to enroll. Our guide to Open Enrollment dates and deadlines explains how the yearly window works.

Frequently Asked Questions
How long do I have to enroll after a qualifying life event?
For many events the window is typically 60 days, but it depends on the event. Check the rules for your situation.
Does losing coverage because I stopped paying premiums qualify?
Usually not. Loss of coverage for failing to pay premiums generally does not open a Special Enrollment Period.
Do I need documents to prove my life event?
Often yes. The Marketplace may ask for proof, so gather documents such as termination letters or marriage or birth records.
Who decides whether I qualify?
The Marketplace decides eligibility. An agent can explain the rules but cannot approve or deny an SEP.
