When can beneficiaries make changes to their TRICARE enrollment?

Beneficiaries can make changes to their TRICARE enrollment during the annual Open Enrollment period or under certain qualifying circumstances, making this the correct answer. The Open Enrollment period typically occurs once a year, allowing individuals to reassess their options and make changes to their coverage as needed. Additionally, qualifying circumstances such as a change in marital status, the birth or adoption of a child, or other significant life events may also allow for changes outside of this annual period.

This ensures that beneficiaries have the flexibility to adjust their healthcare options in response to life changes, which is essential for maintaining adequate and appropriate coverage. By allowing modifications during these specified times, TRICARE provides a structured approach to enrollment modifications, which helps in managing the program effectively.
