What is the Origin of Medical Necessity Definition?

The concept of medical necessity has been a cornerstone of health insurance contracts since the mid-20th century, formalizing the distinction between essential care and elective or cosmetic procedures. It was codified into federal law through government programs like Medicare and further refined by the American Medical Association (AMA) and state regulations. The definition's precise language often varies between insurance plans, creating administrative complexity.

What is the Mechanism of Medical Necessity Definition?

The mechanism operates through a utilization review process, where the insurer's clinical staff assesses the treating physician's documentation, including diagnostic codes and supporting laboratory evidence, against the payer's proprietary or evidence-based clinical guidelines. The review is a systematic check to ensure the treatment is not experimental, is the least costly equally effective alternative, and directly addresses a confirmed pathology, thus justifying the financial expenditure.

Meaning

Medical Necessity Definition is the contractual and legal standard utilized by health insurance payers to determine if a requested medical service, treatment, or supply is eligible for coverage and reimbursement. This definition typically stipulates that the care must be required for the purpose of preventing, diagnosing, or treating an illness or injury and must be consistent with generally accepted standards of medical practice. The interpretation of this term is a frequent point of contention in coverage disputes.
