Coverage decisions can ultimately be traced back to three words in the original health policy contract: medically necessary and investigational. Investigational as a coverage exclusion applies to the minority of cases, in which there is inadequate data to validate the effectiveness of the intervention. In contrast, the majority of coverage decisions are based on medical necessity.
Over the years the concept of medical necessity has evolved to encompass a multitude of medical management strategies. This discussion highlights the variable uses of the concept of medical necessity in terms of: (1) Determining the most appropriate intensity of service and place of service; (2) determining whether the proposed therapy is medically appropriate for the patient's condition; (3) distinguishing between medically necessary services and those that are performance enhancing or discretionary in nature; (4) making a distinction between medically necessary, cosmetic, and reconstructive services; and (5) defining medical necessity in accordance with generally accepted principles of good medical practice.
