Special Open Enrollment

Certain events let you make account changes, like changing a health plan or enrolling a dependent, outside of annual open enrollment. The change in enrollment must be allowable under Internal Revenue Code and correspond to the event that creates the special open enrollment for the subscriber, the subscriber's dependent, or both.

Coverage Dates

  • Health plan coverage will begin the first of the month following the later of the event date or the date the form is received. If that day is the first of the month, the change in enrollment begins on that day.
  • Enrollment of extended dependents or dependents with a disability will be the first day of the month following eligibility certification.
  • If the special open enrollment is due to the birth or adoption of a child, or when the subscriber has assumed a legal obligation for total or partial support in anticipation of adoption of a child, health plan coverage will begin or end the month in which the event occurs.
  • Dependents will be removed from the subscriber's health plan coverage the last day of the month following the later of the event date or the date the form is received. If that day is the first of the month, the change in enrollment will be made the last day of the previous month.
