Q: My wife and I are both CSRS retirees. During our active careers and up to this point in our retirement she has been covered under my family health plan. Now that our youngest son is in the Air Force we want to switch to two single plans. Is that possible? Do we have to do it during open season? A: Yes, you can switch to two self only enrollments, but the only time you can do it is during the annual open season.
