Understanding Open Enrollment & Special Enrollment Periods

What Is Open Enrollment?

Open Enrollment is the annual window when anyone can sign up for ACA health insurance through the Health Insurance Marketplace — regardless of health status, pre-existing conditions, or current coverage. For the 2026 plan year, federal Open Enrollment runs from November 1, 2025 through January 15, 2026. Some states with their own exchanges offer extended deadlines.

What If I Miss Open Enrollment?

If you miss Open Enrollment, you can still get coverage through a Special Enrollment Period (SEP) if you've experienced a qualifying life event within the past 60 days. Common qualifying events include losing employer coverage, getting married, having a baby, or moving to a new area.

What Counts as a Qualifying Life Event?

The most common qualifying life events that trigger a 60-day Special Enrollment Period include:

  • Loss of health coverage — Job loss, aging off parent's plan, COBRA expiration, losing Medicaid/CHIP
  • Changes in household — Marriage, birth/adoption, divorce
  • Changes in residence — Moving to a new ZIP code or county
  • Changes in eligibility — Gaining citizenship, release from incarceration, income changes affecting Medicaid eligibility
