The Newborn Screening Coding and Terminology Guide promotes the use of electronic health data standards in recording and transmitting newborn screening test results. The site includes standard codes and terminology for newborn tests and the conditions for which they screen, provided in a series of tables that you can view on the Web and/or download for your own use. These tables cover conditions recommended for screening by the Advisory Committee on Heritable Disorders in Newborns and Children (ACHDNC) or by a state within the U.S.
