Implementations require mappings to/from SNOMED CT for a wide range of reasons, including:

• To submit statistical reports using classifications, like ICD-10
• To generate codes from procedures vocabularies for billing
• To support data interoperability and data integration
• To enable advanced data analytics over existing data
• To use national medication identifiers in the electronic prescribing process
• To allow the user to select terms from a local interface terminology and record this using SNOMED CT

The tools in this section help implementers to create and manage maps to/from SNOMED CT.
