Open Enrollment Period: Understanding Your Annual Opportunity for Health Insurance Coverage

The Open Enrollment Period (OEP) represents a critical time window when individuals and families can enroll in, change, or renew their health insurance coverage. According to the Centers for Medicare & Medicaid Services (CMS)[^1], this annual period ensures Americans have access to comprehensive health coverage while maintaining stability in the insurance market.

What Is the Open Enrollment Period?

Open Enrollment is the annual timeframe when anyone eligible for health insurance can:

• Enroll in a new health insurance plan

According to HealthCare.gov[^2], the federal Open Enrollment Period for 2025 coverage runs from November 1, 2024, through January 15, 2025, though some state-based marketplaces may have different deadlines.
