Open Enrollment Period

Open Enrollment Period typically will run from November 1 to December 15 of the current year to enroll in a Marketplace health insurance plan for most states. 

Outside Open Enrollment, you may still be able to enroll in Marketplace coverage if you have certain life events, like getting married, having a baby, or losing other health coverage, or based on your estimated household income.

  • Job-based plans may have different Open Enrollment Periods. Check with your employer.
  • You can apply and enroll in Medicaid or the Children’s Health Insurance Program (CHIP) any time of year.

Important dates

  • November 1: Open Enrollment starts for health coverage for the next plan year — first day you can enroll in, renew, or change health plans through the Marketplace. Coverage can start as soon as January 1.
  • December 15: Last day to enroll in or change plans for coverage to start January 1.
