MEDICAL NECESSITY
Back to GlossaryDefinition
Health care services or supplies needed to diagnose or treat an illness, injury, condition, disease, or its symptoms and that meet accepted standards of medicine.
Summary
Medical necessity is a key healthcare concept that determines whether a treatment, service, or medical supply is actually required for a patient's health condition. It's not just about what a doctor recommends, but specifically about services that are essential for diagnosing, treating, or managing a medical condition according to established medical standards. Insurance companies use this concept to decide what they will cover, making it crucial for both healthcare providers and patients to understand.
Usage Context
Understanding medical necessity is critical when studying healthcare policy, insurance coverage, healthcare economics, medical ethics, and healthcare administration. It's particularly important when analyzing coverage decisions, healthcare costs, and the relationship between clinical care and insurance systems.
