Which type of service is usually not covered by health insurance?

Cosmetic surgery is typically not covered by health insurance unless it is deemed medically necessary. This means that if the surgery is performed solely for aesthetic reasons, it will usually fall outside the covered services of most health insurance plans. Insurers prioritize covering services that are medically necessary for health outcomes, such as surgeries required to repair injuries or to address functional impairments.

In contrast, preventive care and routine vaccinations are often covered fully by health insurance plans as part of initiatives to promote public health and prevent illnesses. Emergency room visits are also generally covered since they involve acute, potentially life-threatening conditions requiring immediate medical attention. The distinction lies primarily in the intent and necessity of the procedure, where cosmetic procedures do not align with the primary goal of health insurance to provide care for essential health needs.
