One immediate impact of the DOMA decision is that all "legally married" – that is, persons married in a state that recognizes such unions, regardless of whether they are living in such a state or in one that doesn’t recognize them — same-sex spouses will now be eligible family members under FEHBfamily enrollment.Also, any children of a couple in a same-sex marriage will be treated just as those of opposite-sex marriages and will be eligible family members according to the same eligibility guidelines. This includes coverage for children of same-sex spouses as stepchildren.Enrollees will have until August 26 to change their enrollment for the current plan year, using the standard FEHB enrollment form; enrollments will be effective at the start of the following pay period. After that, they won’t be able to make such changes until the open season in the fall for the 2014 plan year. Similar policies apply in the FEDVIP vision-dental insurance program.
