A reference set designed to support the process of mapping data from one code system, classification, or terminology to another code system, classification, or terminology.
Notes
- There are several types of mapping reference set each of these supports different types of mapping.
- Simple Map from SNOMED CT Reference Sets and Simple Map to SNOMED CT Reference Sets support one-to-one maps from or to SNOMED CT.
- Complex and Extended Map from SNOMED CT Reference Sets support maps where additional information is required to determine the correct mapping from SNOMED CT to a statistical classification such as ICD-10.
- Maps which have a requirement to indicate the degree of correlation between a SNOMED CT concept and other codes. (See Map Reference Sets which use "correlation" within their type / name.)
- Code to Expression Reference Sets support maps from other code systems in cases where some or all the source codes may need to be represented by a postcoordinated expression.
