Change in sponsor's status:
1. Retiring or separating from active duty
2. National Guard or Reserve member activation or de-activation
3. Change in service status (e.g. enlisted to officer, branch change)
4. Getting married or divorced
5. Having a baby or adopting a child (NOTE:  DEERS registry is a separate step and is required before you can enroll a child in TRICARE Prime)
6. Moving to a new location for any reason
7. Becoming entitled to Medicare (either you or a family member)
8. Death of sponsor or family member

TRICARE is the health care program serving Uniformed Service members, retirees and their families worldwide. There are three regions; North, West, and South. 9th District falls under all three depending on your location.

Marines and Family Members: If you are currently enrolled in TRICARE Prime “DO NOT DIS-ENROLL.” Please check the ruling on “portability” with your local TRICARE Service Center at your current installation.  Once you get to your new duty station, you will need to enroll into your new health care region, which will also automatically transfer service from your old region.

NOTE: All active duty personnel MUST enroll into TRICARE Prime Remote that are in remote locations (Single or Married Marines). Eligible family members residing with Active Duty member may also enroll in Prime Remote or select the Standard or Extra option.
