title: Nonsynonymous synonyms: correcting and improving SNOMED CT.
abstract: SNOMED CT was created from a merger of SNOMED RT and United Kingdom's National Health Service's Clinical Terms Version 3. The resulting terminology has a plethora of synonymous terms. This paper discusses how a review synonyms in the Procedure section of SNOMED CT revealed some nonsynonmous synonyms, hypothesizes why errors in synonymy may have occurred, and explains the steps taken to resolve nonsynonymous concepts previously assigned to synonyms.
