Defense Enrollment Eligibility Reporting System (DEERS)
DEERS registration is essential for your family to be eligible for TRICARE. The following overview will assist you in registering for DEERS and verifying and updating your DEERS information.
DEERS is a computerized database of military sponsors, families and others worldwide who are entitled under the law to TRICARE benefits. Active-duty and retired service members are automatically registered in DEERS, but you must take action to register your family members and make sure all the information is correct to ensure TRICARE coverage.
You can verify your DEERS information by contacting your regional TRICARE managed care support contractor, your local TRICARE service center or the nearest personnel office (ID card facility). Sponsors or registered family members can make address changes, but only the sponsor can add or delete family members, and documentation is required. To update your DEERS information:
- Visit your personnel office or contact the Defense Manpower Data Center Support Office at 800-538-9552. You can find your nearest personnel office at: http://www.dmdc.osd.mil/rsl/.
- Visit the DEERS website at https://www.dmdc.osd.mil/appj/bwe/indexAction.do.
- Go online to TRICARE to update your information: http://www.tricare.mil/DEERS .
- Each family member's eligibility record must be updated separately when changes occur.
- Any changes that impact you or your family (e.g., marriage, birth, divorce, death) need to be reported to DEERS so that eligibility can start or stop under DoD and Service guidance.
- If you are active duty and re-enlist, separate, retire, or move, make sure your information gets updated in DEERS as soon as possible. If you do not, you and your family might experience a break in eligibility, which means a break in health care coverage.
- As soon as you re-enlist, take your reenlistment paper to your personnel support center or ID card facility so your information can be updated before your previous enlistment expires rather than waiting for the paperwork to go through distribution.
- Once you retire, you need to make sure DEERS reflects your change from active duty to retiree status.
Note: If you or your family were previously TRICARE Prime under your active duty status, you need to re-enroll in TRICARE Prime under your retiree status. Contact the regional managed care support contractor (MCSC) in your retirement location to find out if TRICARE Prime is offered in your retirement area ZIP code.
- It is important to update your and your family's home addresses because TRICARE Program information will be sent to that address.
- Retail network pharmacies check TRICARE eligibility through DEERS. Your prescriptions will be filled only if you are in the system.
- If you have a child that is over age 21 and a full-time student, you need to get his or her student status entered into DEERS so that TRICARE eligibility is not interrupted and access to health care is not lost.
- If you or a family member is Medicare-eligible, entitled to Part A and enrolled in Part B, DEERS must be updated to reflect MEDICARE Part A and B status to retain TRICARE coverage. When you turn 65, the medical section of your military ID card may also need to be updated.
