Which service is NOT covered by Medicare?

Assisted living costs are not covered by Medicare because Medicare is primarily designed to provide health insurance for individuals aged 65 and older and for certain younger people with disabilities. It specifically covers medically necessary services, but it typically does not cover room and board in assisted living facilities. Such facilities provide a home-like environment and assistance with daily activities but do not qualify as a medical service.

In contrast, services like short-term rehabilitation following hospitalization, long-term care in skilled nursing facilities under certain conditions, and home health aide services may be covered by Medicare as long as specific eligibility criteria are met, such as being medically necessary and provided under a plan of care developed by a physician. This distinction illustrates Medicare's focus on acute and post-acute care rather than custodial care, which is commonly provided in assisted living settings.
