Open Enrollment Period

Insurance Glossary

The annual window during which a person can enroll in a health plan or switch plans without needing a special reason. The Marketplace period runs in the fall for coverage starting January 1, with dates varying in states that operate their own exchange, and employer plans set their own window each year. Outside it, enrolling generally requires a qualifying life event that opens a special enrollment period.
