managed care
any system of health care delivery that regulates the use of member benefits to contain expenses. The term originally referred to prepaid health plans (e.g., HMOs) but is now applied to many different kinds of reimbursement and utilization review mechanisms. It is also used to denote the organization of health care services and facilities into groups to increase cost-effectiveness. Managed care organizations (MCOs) include HMOs, PPOs (preferred provider organizations), point-of-service plans (POSs), exclusive provider organizations (EPOs), physician–hospital organizations (PHOs), integrated delivery systems (IDSs), and independent practice associations (IPAs).
