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

TRICARE Prime is structured to function within a managed care model, which prioritizes coordinated healthcare services. One of the key features of TRICARE Prime is that it requires beneficiaries to enroll and select a Primary Care Manager (PCM). The PCM serves as the main point of contact for all healthcare needs, coordinating referrals and services, which contrasts with unrestricted access to any provider.

Offering no out-of-pocket costs for most covered services is another characteristic of TRICARE Prime, making healthcare affordable for its beneficiaries. Additionally, the program strongly emphasizes preventive care and disease management, aiming to promote overall health and prevent the development of more severe health issues.

In contrast, the option that states beneficiaries have unlimited access to any provider does not align with how TRICARE Prime operates. This feature misrepresents the necessity for referrals and the established network of providers within TRICARE Prime, which is instrumental in maintaining the program's cost-effectiveness and care coordination. Thus, the statement regarding unlimited access is not an accurate representation of TRICARE Prime's functions and structure.
