- Reviewed by John Krahnert
In order for a health care service to be covered by Medicare Part A or Part B, it must be deemed medically necessary.
“Medically necessary” is defined as health care services or supplies that are necessary to prevent, diagnose, or treat an illness, injury, condition, disease, or their symptoms within accepted standards of medicine.
In other words, medically necessary services consist of health care that is necessary to keep you healthy.
