Split Enrollment

The split enrollment option allows your entire family to enroll in TRICARE Prime even if part of your family is living in another TRICARE region. This allows families with college students, children living with former spouses, or families otherwise separated to enroll together in separate regions and pay one enrollment fee, if applicable.

To use the split enrollment option, notify the regional contractor in each region to establish a primary payer (usually the sponsor), if you pay enrollment fees.

Region	Contractor and Phone Number
East Region	Humana Military: 800-444-5445
West Region	TriWest Healthcare Alliance: 888-TRIWEST (874-9378)
