Patient discharge summaries are typical unstructured text which is not amenable for processing by an automated system. For an efficient electronic healthcare system, free-form medical texts generated at various subsystems need to be mapped into standard codes like ICD-10, SNOMED-CT, etc. The Unified Medical Language System (UMLS) unifies these standard codes into a set of concepts identified by a Concept Unique Identifier (CUI). In this paper, we have used NLP techniques to map clinical narrative texts found in discharge summaries to CUIs. We have developed a Matcher algorithm to match the clinical text strings to that of UMLS and thereby extract the concepts. We achieve 70% similarity between the set of concepts generated using our Matcher algorithm to that of a gold standard tool.
