6.5. Mapping Context - Acquired Versus Congenital

A source concept which identifies origination as a congenital or acquired condition will be mapped to a target of congenital or acquired classification should one exist (mapCategoryId="Properly classified", mapRule=NULL).

If a source concept is general (i.e. does not specify congenital or acquired) and only specific targets exist, the ICD-10 authoritative source index will be searched for guidance of a default Map member, either "congenital" or "acquired". When a default is provided, this context will be employed to create one appropriate Map member and mapCategoryId will be  447637006 | Map source concept is properly classified| Properly Classified, mapRule=NULL, mapAdvice = "MAPPED FOLLOWING WHO GUIDANCE".
