What are examples of non-covered services by Medicare?

Medicare generally does not cover services that are deemed not medically necessary or that are primarily for cosmetic purposes. Cosmetic surgeries, most dental care, and routine foot care fit this criteria. Cosmetic surgeries are specifically designed for aesthetic improvement rather than to treat a medical condition. Most dental care, such as routine cleanings or fillings, is often not covered because Medicare only offers limited coverage for dental emergencies or surgeries related to the jaw. Routine foot care typically involves services like nail trimming or callus removal, which are considered non-essential unless the patient has a specific medical condition, such as diabetes, that necessitates these procedures.

In contrast, services like inpatient hospital stays, emergency room visits, and preventive services are generally covered by Medicare as they are fundamental to medical treatment and health maintenance. This distinction underscores why the correct answer points to services that fall outside the scope of medically necessary care, marking them as non-covered by Medicare.
