Which of the following is NOT a variation of TRICARE Prime?

The option that stands out as not being a variation of TRICARE Prime is TRICARE Extra. TRICARE Prime is a managed care option that provides comprehensive healthcare services, and its variations include TRICARE Prime Remote, which is tailored for active duty service members and eligible family members living away from their primary duty station; and TRICARE Reserve Select, which is a premium-based plan for eligible Selected Reserve members and their families.

TRICARE Extra, on the other hand, is a point-of-service option that falls under the TRICARE Standard umbrella and provides a different kind of access to care compared to the managed care model of TRICARE Prime. It allows beneficiaries to receive care from a network of providers without needing a referral, but it is not categorized as a variation of TRICARE Prime.

Understanding the distinctions between these options is important as they are designed to meet the varying healthcare needs and circumstances of military families.
