The American College of Medical Quality defines ________ as 'accepted healthcare services and supplies provided by healthcare entities, appropriate to the evaluation and treatment of a disease, condition, illness or injury and consistent with applicable standard of care.'

• A. Medical necessity
• B. Utilization management
• C. Managed care
• D. Preventative care

Answer: (A)

Medical necessity defines whether healthcare services and supplies are eligible for coverage because they are necessary to diagnose or treat a condition and align with the standard of care. This concept focuses on services that are appropriate to evaluate or treat a disease, condition, illness, or injury and that are consistent with accepted professional standards. In practice, payers use medical necessity to determine which interventions will be reimbursed, ensuring that care is appropriate and not excessive or experimental.

Other terms describe related ideas but not the definition itself. Utilization management is the process of reviewing care to determine appropriateness and necessity, often as a step in deciding whether to authorize services. Managed care refers to a broader system that coordinates financing and delivery of care to control costs. Preventative care covers services aimed at preventing disease or detecting it early, rather than treating an existing condition.
