When an employee chooses to not enroll in coverage because she has other coverage, she may once again become eligible to enroll, if she loses her former insurance coverage, or if contributions towards the other coverage cease. The employee has the option to enroll, but must do so within 31 days of loss of coverage, or within 31 days of the other employer no longer contributing.
Coverage for newly eligible dependents begins on the date they become a dependent (i.e. birth, adoption, marriage) as long as the employee enrolls them within the 31 day limit. This special enrollment right is additional to the qualified status changes listed previously.
