Final answer:
Possessing a TRICARE Prime identification card does not guarantee TRICARE eligibility as eligibility is determined by various factors, including an individual's military status and entitlements.
Step-by-step explanation:
The statement "A TRICARE Prime identification card guarantees TRICARE eligibility." is false. A TRICARE Prime identification card indicates that an individual is enrolled in the TRICARE Prime program, which is a health care plan available to military members, retirees, and their dependents. However, simply possessing the identification card does not guarantee eligibility. Eligibility for TRICARE is determined by several factors, including the individual's status with the Department of Defense and their specific entitlements as a current or former service member or dependent.
It is important to note that eligibility must be formally established and maintained according to the rules and regulations of the TRICARE program. Enrolled members must ensure that their eligibility status remains current to continue receiving TRICARE benefits.
