Enrolling or switching your health plan is easier than you’d expect
Newly eligible employees generally have 60 days to enroll in a health plan.
- If you don’t make an election, you are considered to have declined coverage.
Your next enrollment opportunity will be Open Season unless you have a qualifying life event (QLE), such as marriage or the birth of a child.
- A QLE may make you eligible to enroll or change your FEHB coverage outside of Federal Benefits Open Season.
During the annual Federal Benefits Open Season, anyone eligible to participate in the FEHB Program may enroll, change health plans or options or cancel their FEHB enrollment.
- If you’re enrolling during Open Season, you have from November 11 to December 9, 2024, to enroll or change your enrollment.
You can consult with your agency’s human resources office or check the FEHB Program Handbook for more information about qualifying life events and details about Federal Benefits Open Season.
