Health insurance cannot really be insurance because human health is un-insurable: human beings are not machines or buildings whose function or condition can be ascertained objectively. Yet, an objective assessment of damages and costs is essential for any contractual arrangement to function in a sustainable manner.
Consider, for example, that medical care is based on the legal principle of “medical necessity.” Medical necessity is invoked when, presumably, there is an impairment in the patient’s health that could be remedied by a medical intervention. But medical necessity is a perniciously elastic concept that cannot possibly satisfy the precise contractual requirements of insurance.
