What services are not covered by TRICARE?

The correct option highlights that certain services such as cosmetic surgery, infertility treatments, and certain alternative therapies are not covered by TRICARE because they are typically considered non-essential or elective in nature. TRICARE is designed primarily to cover medically necessary services and treatments. Cosmetic surgery is generally viewed as a procedure that is not needed for medical reasons unless there are underlying health issues that require surgical intervention. Infertility treatments often fall outside of standard coverage due to the nature of the services being more related to personal choice rather than medical necessity. Similarly, certain alternative therapies may lack sufficient scientific evidence demonstrating their effectiveness and safety, leading to their exclusion from coverage.

In contrast, routine vaccinations and check-ups are part of preventive services supported by TRICARE, ensuring beneficiaries receive necessary immunizations and health screenings. Emergency care usually has specific coverage provisions, even when provided outside the network, to protect individuals in urgent situations. Hospital stays for observation are often covered under TRICARE when deemed medically necessary, as they relate directly to the evaluation of patient health. Thus, option B is correct because it outlines services deemed non-essential and typically not included in TRICARE coverage.
