Which statement best describes the TRICARE Select program?

The TRICARE Select program is a preferred provider option that provides beneficiaries with a broader choice regarding their healthcare providers. The correct statement describes that TRICARE Select requires enrollment, which means individuals must sign up to participate in the program. Additionally, one of its key advantages is that it offers lower costs for in-network care. This makes it a more cost-effective choice for those who opt for services provided by network providers, compared to using out-of-network services that typically come with higher costs.

In contrast, the other options fail to accurately characterize the program. For instance, it is not limited solely to retired military personnel, as it is available to a wider range of eligible beneficiaries. Moreover, while it does require enrollment, its costs are not equivalent to TRICARE Prime; TRICARE Select typically has different cost structures and benefits. Lastly, it is not the only option available to active duty service members, who primarily use TRICARE Prime for their healthcare coverage. Thus, the elements of enrollment and cost structure in network care make the selected statement the most accurate reflection of the TRICARE Select program.
