Special Enrollment Periods

Special Enrollment Periods allow eligible people to enroll in or change Marketplace coverage outside the annual Open Enrollment window after certain life events or circumstances.

By the Health Insurance Match Editorial Team · Last reviewed July 14, 2026

Common Qualifying Events

Examples can include losing qualifying coverage, marriage, birth or adoption, certain moves, and other changes. The details differ by event, and voluntarily dropping coverage or losing it for nonpayment may not create the same rights.

Timing and Documentation

Enrollment windows can begin before or after an event and often require prompt action. The Marketplace may request proof of the event, prior coverage, residence, or eligibility. Keep notices and submit documents by the stated deadline.

Coverage Effective Dates

Start dates depend on the event, application date, plan selection, and current rules. A birth or adoption may follow different timing from a move or loss of coverage. Confirm the effective date before ending existing coverage.

Key Points to Compare

Item Why it matters
Loss of coverage Employer, individual, Medicaid/CHIP, or family coverage under qualifying rules
Household change Marriage, birth, adoption, placement, or certain loss tied to divorce/death
Move Qualifying permanent move with applicable prior-coverage rules
Other circumstance Marketplace determination based on current policy
