Changing Mutable Description Attributes

• Changing the active attribute to 0 (i.e. inactive).  For more information, please refer to Inactivating a Description in an Extension.
• Changing the term of the description. Please note that only limited changes may be made to the term field field, as defined by editorial rules.
  • The International SNOMED CT Editorial Guide states when making a minor change to an FSN, a new description must be created and the old description must be inactivated. 
  • Permitted changes include modifications that do not alter the meaning, for example a spelling correction. For a list of permitted changes, please refer to the appropriate section of the Editorial Guide:
    • FSNs - refer to Changes in the Fully Specified Name
    • Other description types - refer to  capitalization
  • When in doubt, an extension producer should inactivate the description and add a new description with the required term.
