Which of the following statements about Tricare Prime is true?

The statement regarding Tricare Prime being true is based on how the healthcare system is structured under this program. Tricare Prime is a managed care option that emphasizes coordinated health care through an assigned Primary Care Manager (PCM). Members enrolled in Tricare Prime are typically required to receive the majority of their care from this designated PCM, who is responsible for overseeing their health needs, managing referrals to specialists, and directing further care as necessary. This model allows for streamlined and efficient medical services, which helps in maintaining continuity of care for patients.

The other provided options do not accurately reflect the nature of Tricare Prime. For instance, while there are enrollment fees for certain groups, they are not universally high for all members. Additionally, Tricare Prime is available not only to retired members but also to active-duty service members and their families. Furthermore, it is not limited to emergency services; rather, it encompasses a full range of health services beyond just emergencies, including routine check-ups, preventive care, and specialty care with appropriate referrals from the PCM.
