Special Enrollment Period

If you have a qualifying life event or change like losing your Medicaid coverage, getting married, having or adopting a baby, or starting a new job, you may be able to enroll in a health plan during the Special Enrollment Period. Special Enrollment takes place when the Open Enrollment Period ends each year and continues until it begins again in November.

During Special Enrollment, you can choose a new Individual and Family plan with a qualifying life event.1
