What You Need to Know About Tricare Open Enrollment

Tricare open enrollment, commonly referred to as the open season, is the annual period during which beneficiaries can make changes to their health coverage. For the upcoming 2026 cycle, this window will be open from November 9 through December 8. This timeframe is critical for service members and Veterans who wish to switch plans, add or remove dependents, or adjust their coverage options for the following year. Missing these specific dates can result in being locked into the current plan until the next annual period, so it is important to review your options well in advance.
