The<unk> <unk>  is a systematic, computer-processable collection of medical terms, in human and veterinary<unk> , to provide codes, terms, synonyms and definitions which cover anatomy, diseases, findings, procedures, microorganisms, substances, etc. It allows a consistent way to index, store, retrieve, and aggregate medical data across specialties and sites of care. Although now international,<unk>  was started in the U.S. by the College of American Pathologists (CAP) in 1973 and revised into the 1990s. In 2002 CAP's<unk>  Reference Terminology<unk>  RT) was merged with, and expanded by, the National Health Service's Clinical Terms Version 3 (previously known as the Read codes) to produce<unk>  CT. Versions of<unk>  released prior to 2001 were based on a multiaxial, hierarchical classification system. As in any such system, a disease may be located in a body organ (anatomy), which results in a code in a topography axis and may lead to morphological alterations represented by a morphology code. In 2002 the first release of<unk>  CT adopted a completely different structure. A sub-type hierarchy, supported by defining relationships based on description logic, replaced the axes described in this article. Versions of<unk>  prior to<unk>  CT are planned to be formally deprecated from 2017. Therefore, readers interested in current information about<unk>  are directed to the article on<unk>  CT.
