If the source concept asserts a gender restriction, a target will be selected including the restriction. If no targets with restriction apply, a more general target will be chosen. The mapCategoryId will indicate that the source is properly classified ( ) in ICD-10, the mapRule will default to TRUE and mapAdvice will be NULL.  The first IF A rule applied should be female; the latter should be male.  This will prevent any sequencing discrepancies from resulting.

If the source concept does not assert gender, yet only gender restricted target codes are found within ICD-10, the map will be considered CONTEXT DEPENDENT. The Map Terminologist will create three Map members for this source concept, including rules for mapping to female and male record context as appropriate to the ICD-10 structures, and a default record indicating that the concept is not classifiable in the absence of gender information.
