If you were not enrolled in FEHB, or if you were enrolled in Self Only coverage, your survivors are not eligible for FEHB benefits. If enrollment doesn’t continue, your survivors may qualify for Temporary Continuation of Coverage (TCC).
If you died while enrolled in Self and Family coverage, and all the requirements were met, your enrollment will continue for your eligible family members who become survivor annuitants under a qualifying retirement system.
If you died while enrolled in Self Plus One, only your designated eligible family member will be able to continue enrollment as a survivor annuitant, if they meet all requirements. Any eligible family members not designated and/or covered under your Self Plus One enrollment will not be eligible to continue enrollment as survivor annuitants.
If you were an employee at the time of your death and the enrollment continues, your eligible survivors are entitled to the same benefits and Government contribution as active and retired employees enrolled in the same plan. The survivor annuitant's share of the premiums normally is deducted from his/her annuity payments. Your survivors don't need to take any action to continue your enrollment if they meet all the requirements.
You can find more information in the FEHB Handbook.
