Missed Open Enrollment? How Special Enrollment Periods Work

What counts as a qualifying life event, how long you have to enroll, what proof you may need, and what to do if you don't qualify for a Special Enrollment Period.

Key takeaways
  • A qualifying life event usually gives you 60 days to enroll in an ACA plan.
  • Losing coverage, moving, marriage, and having or adopting a child are the most common events.
  • Quitting a plan voluntarily or not paying premiums generally doesn't qualify.
  • No qualifying event? Private plans are often available year-round.

ACA Marketplace plans have an annual open enrollment period that typically starts November 1. Outside that window, you need a Special Enrollment Period (SEP) to enroll in or change an ACA plan. SEPs are triggered by qualifying life events.

Common qualifying life events

  • Losing health coverage: leaving a job, aging off a parent's plan at 26, losing Medicaid or CHIP eligibility, or COBRA ending.
  • Changes in household: marriage, divorce in some cases, having a baby, adopting a child or placing a child for foster care, or a death in the family.
  • Moving: to a new ZIP code or county, provided you had qualifying coverage before the move in most cases.
  • Other events: gaining U.S. citizenship or lawful presence, leaving incarceration, and certain income changes.

How long do you have?

Generally 60 days from the event. For loss of coverage you can often report it up to 60 days in advance so your new plan starts with no gap. Coverage start dates depend on the event and when you select a plan.

Will you need proof?

Often, yes. The Marketplace may ask for documents such as a letter showing coverage ended, a lease or utility bill for a move, or a marriage or birth certificate. Upload them promptly so your enrollment isn't delayed or cancelled.

Advisor tip: Voluntarily dropping coverage, or losing it because you didn't pay premiums, generally does not count as a qualifying event.

What if you don't qualify?

  • Private health plans: many can be applied for any time of year, subject to underwriting.
  • Supplemental coverage: accident, critical illness, dental and vision plans are often available year-round.
  • Plan ahead: put open enrollment on your calendar so you don't get stuck next year.
