What is a special enrollment period and do I qualify?

Life events that let you enroll outside open enrollment, the 60 day deadline, and the proof you will need.

Updated August 17, 2026 · 2 min read


Outside open enrollment, you need a qualifying life event to buy a Marketplace plan. That opens a special enrollment period, usually 60 days long.

Events that qualify

Loss of coverage:

Household changes:

Moves:

Other:

What does not qualify

This is why going without coverage is a real risk rather than a theoretical one. A diagnosis does not open a door. If you are uninsured and outside open enrollment without a qualifying event, you may be waiting until November.

The deadline

Sixty days from the event, in most cases. For a loss of coverage you can also apply up to 60 days before it happens, which is the better move when you have notice, because it avoids a gap.

Moving requires that you had coverage for at least one of the 60 days before the move, with limited exceptions.

Proof

The Marketplace will usually ask for documentation. Have it ready.

Upload it promptly. Missing the document deadline can cancel the enrollment you just completed. See the document checklist.

When coverage starts

Usually the first of the month after you enroll. For birth or adoption, coverage can be backdated to the date of the event.

If you are between coverage right now, apply today rather than at the end of the window, since the start date depends on when you enroll rather than when the event happened.

See coverage after losing a job.

Common follow-up questions

How long is a special enrollment period?

Usually 60 days from the qualifying event. For a planned loss of coverage you can apply up to 60 days beforehand.

Does getting sick qualify?

No. A diagnosis is not a qualifying event, which is the main argument for not going without coverage.

Do I have to prove the event?

Usually yes. Have documentation ready and upload it quickly, because missing the deadline can cancel your enrollment.
