Maintaining Your Eligibility for TRICARE

DEERS

It's Your Responsibility

Proper registration in the Defense Enrollment Eligibility Reporting System (DEERS) is the key to receiving timely and effective TRICARE benefits. DEERS is a worldwide, computerized database of uniformed services members (sponors), their family members, and others who are eligible for military benefits, inlcuding TRICARE. All sponsors (active duty, retired, National Guard, or Reserve) are automatically registered in DEERS. However, the sponsor must register eligible family members. After family members and sponsors are registered , they can update personal information such as addresses and phone numbers. Note: If both parents are active duty service members, then either parent (must choose one) may be listed as the child(ren)'s sponsor in DEERS.

When There's a Change

You should update DEERS immediately whenever you experience any of the following life events (this list is not all-inclusive):

  • Change in sponsor's status:
  • Retiring or separting from active duty
  • National Guard or Reserve member activiation or deactivation
  • Change in Service status (e.g., enlisted to officer, branch change)
  • Getting Married or divorced
  • Having a baby or adopting a child. (Note: DEERS registry is a separate step and is required befor you can enroll a child in TRICARE Prime.)
  • Moving to a new location for any reason
  • Becoming entitled to Medicare (either you or a family member)
  • Death of a sponsor or family Member

Updating DEERS

To register family member or update DEERS records, sponsors must complete a DD Form 1172 Application for Uniformed Services Identification Card and DEERS Enrollment and provide documentation, such as marriage, birth, or death certificates; Social Security numbers; active duty separation papers; Medicare cards. Each family member's eligibility record must be updated separately. Note: If the sponsor is not available, family members can update DEERS with a notarized DD Form 1172 or if you have Power of Attorney. You can verify and update DEERS in one of the following ways:

 1

To add or delete family members, visit a local uniformed services personnel office. Search for an office near you by ZIP code, city or state at www.dmdc.osd.mil/rsl. Call the office first to verify location and business hours.

 2

Call the Defense Manpower Data Center Support Office (DSO) at 1-800-538-9552 to update your addresses, e-mail addresses, and phone numbers.

 3

Fax address, e-mail addresses, or phone number changes to the DSO at 1-831-655-8317.

Loss of Eligibility

If you try to obtain care and your DEERS record shows you as ineligible for TRICARE (but you have not truly lost TRICARE eligibility), you'll need to update your DEERS information. For more information about Loss of Eligibility, visit www.tricare.mil/certificate.
