Professional Standards Review Organization (PSRO), an organization formed under the U.S. Social Security Act Amendments of 1972 to review the services provided under Medicare, Medicaid, and Maternal Child Health programs. Review is conducted by physicians to ascertain the need for the program and to ensure that it is carried out in accord with certain criteria, norms, and standards and, in institutional situations, in a proper setting. The PSRO requires that regional organizations be formed to conduct these reviews throughout the nation.
