Pronunciation: pre'aw-thor-i-za'shun


A prerequisite, often intended as a rate-limiting or cost-containment step, in the provision of care and treatment to an insured patient. A practitioner who expects to be paid for a service must use paperwork and telephone contact with a designated entity (often clerks, but sometime medical professionals), often a TPA, to determine whether the proposed treatment or procedure is deemed medically necessary for the health and welfare of the covered party.
