A term used extensively in managed care and, to many, implies the primary process of “managing” managed care. Approval usually is used to describe treatments or procedures that have been certified by utilization review. Can also refer to the status of certain hospitals or doctors, as members of a plan. Can describe benefits or services which will be covered under a plan. Generally, approval is either granted by the managed care organization (MCO), third party administrator (TPA) or by the primary care physician (PCP), depending on the circumstances.
