Key takeaways

  • Most SEPs last about 60 days from the event.
  • Loss-of-coverage windows can start up to 60 days early.
  • Act fast and keep documentation of the event.

The general window

After a qualifying life event, you usually have about 60 days to enroll in or change a plan. For some events, like losing coverage, the window can also open up to 60 days before the event, so you can line up new coverage with no gap.

When the clock starts

The clock typically starts on the date of the event (the day coverage ends, the marriage date, the move date, and so on). Miss the window and you generally wait for the next Open Enrollment, unless another qualifying event occurs.

  • Loss of coverage: 60 days before or after
  • Marriage, birth, adoption, move: usually 60 days after
  • Have documentation of the event ready

Do not wait

Because the window is short and requires documentation, the safest move is to confirm eligibility and start right away. A licensed agent verifies whether your event qualifies and helps you enroll before the deadline, at no cost.
