SNOMED CT (Systematized Nomenclature of Medicine - Clinical Terms) is considered to be the most comprehensive, multilingual clinical healthcare terminology in the world. It is designed for use in clinical documentation in the Electronic Health Record (EHR). SNOMED CT is one of the required standards for procedures in the 2014 Certification Criteria for EHR products that may be used to qualify for meaningful use incentives. This map is designed to support a transition from the use of legacy ICD-9-CM procedure codes to SNOMED CT.
The most useful mappings are the one-to-one maps, in which a single SNOMED CT concept can be used to represent the full meaning of an ICD-9-CM code. This allows the automatic translation of ICD-9-CM codes into SNOMED CT codes without loss of meaning. In the creation of the map, we tried to identify as many one-to-one maps as possible. However, due to the differences between the two coding systems, this is not possible for some ICD-9-CM codes. The Map is published in two separate files, one containing the one-to-one (exact) maps, and the other the one-to-many (partial) maps. In the partial maps, the target SNOMED CT concept can be broader or narrower than the meaning of the ICD-9-CM code.
