Key points

If you missed Open Enrollment, a qualifying life event can still let you enroll through a Special Enrollment Period (SEP).
In most cases, you must apply within 60 days of the event.
Illness or pregnancy alone generally does not qualify you for a Special Enrollment Period.
You can apply for Medicaid year-round, regardless of Open Enrollment.
Without a qualifying event, you generally need to wait for the next Open Enrollment.

1. What can qualify you for a Special Enrollment Period?

These are common situations listed by the federal marketplace, HealthCare.gov. States with their own marketplaces generally have similar rules:

1. Losing coverage

Losing employer coverage because you leave a job, are laid off, the employer stops offering coverage or for similar reasons.
COBRA running out.
Losing Medicaid or CHIP, the children's health insurance program.
Losing student insurance.
Turning 26 and no longer being eligible for a parent's plan.
Losing coverage through a family member because of divorce, separation or the family member's death.

2. Family changes

Getting married.
Having a baby, adopting a child or starting a foster placement.

3. Moving

Moving to a new ZIP code or county.
Moving to the United States from another country or a US territory.

4. Other situations

Becoming a US citizen.
Leaving incarceration.
Being a member of a federally recognized tribe.
An employer offering individual health coverage reimbursement through an ICHRA or QSEHRA.
Missing enrollment because of a natural disaster or another unexpected event outside your control.

2. How long do you have to apply?

Situation	Application window
Losing employer coverage	From 60 days before to 60 days after coverage ends. Applying early can help avoid a gap.
COBRA running out	Within 60 days after COBRA ends
Losing Medicaid or CHIP	Within 90 days after coverage ends
Marriage	Within 60 days after the wedding
Birth, adoption or foster placement	Within 60 days of the event
Moving	Within 60 days after the move

In states with their own marketplaces, follow that marketplace's application windows.

3. When does coverage start?

In most cases: The first day of the month after you choose a plan.
Birth, adoption or foster placement: Coverage can start on the date of the event, even if you apply later within the 60-day window.
Losing employer coverage: Applying before it ends can let the new coverage start immediately afterward, without a gap.

4. What does not qualify?

Getting sick or being diagnosed with a major illness: Does not qualify.
Pregnancy alone: Does not qualify in most states; the baby's birth does. Pregnant women who meet income requirements can apply for Medicaid at any time.
Voluntarily canceling coverage, or having it canceled for nonpayment: Does not qualify.
Voluntarily ending COBRA before it runs out: Does not qualify.
Divorce or separation without losing coverage: Does not qualify.
Wanting a different plan because premiums are too high: Does not qualify; you need to wait for Open Enrollment.

5. A few things to watch

You may need to provide proof. Examples include a separation letter, coverage termination notice, marriage certificate, birth certificate, or a lease or utility bill for a move. Coverage may be canceled if you do not submit documents on time.
Moving has conditions. Generally, you must have had qualifying health coverage for at least one day during the 60 days before your move. Exceptions include moving back from another country.
You can appeal a denial. If you believe you qualify but are denied, you can file an appeal.
Do not wait until you get sick to enroll. Without a qualifying event, even illness does not let you enroll before Open Enrollment.
