Enrollment Eligibility Reporting System (DEERS) is a
world-wide database of active duty family members,
retirees and their family members, and others who are
eligible for TRICARE benefits. Although active
duty service members and military retirees are
automatically registered in DEERS, active duty family
members (ADFM) and eligible survivors must physically
Because DEERS information is not automatically
updated, you must update your file when you move. When DEERS files
are outdated, problems arise. This is especially true of incorrect
home addresses. Information listed in DEERS is frequently used to
send out information about health benefits. About half of the
addresses for AFDMs are estimated to be incorrect because DEERS was not
updated when the families moved.
Problems also arise when DEERS is not notified
of a change in the family status, such as marriage, divorce, birth or
adoption. Your TRICARE benefits may be denied because DEERS has
not been updated to reflect a new spouse or child. A claim may
also be paid by mistake because DEERS has no record of divorce or death.
With an incorrectly paid claim, the government is required by law to
request reimbursement, regardless of who is at fault.
