Complex Map Type Reference Sets
Complex Maps are used for one-to many or many-to-one mappings, where you can specify rules and advice for the map execution as well as the level of generalization or specialization. One-to-many mappings are displayed in the table in separate lines.
SNOMED CT Concept to any other Code System mappings are allowed.
To create a new Complex Map type Reference Set, right-click on a Reference Set type grouper concept in the Reference Set and select the New Complex Map type Reference Set Context Menu option.
Members can be added the same way as to a Simple type Reference Set.

Map priority | Specifies the order in which Complex Map records should be checked within a map group |

Map rule | A machine-readable rule, (evaluating to either |
Map advice | Human-readable advice, that may be used to give an end-user advice on selection of the appropriate target code from the alternatives presented within the group |
Some of the properties can be modified afterward from the Complex Map type Reference Set Editor. In-cell editing is allowed in the specified member fields such as groupNumber, mapPriority, mapAdvice, mapRule, correlation, mapCategory columns when authoring Complex Map Type Reference Sets.
SNOMED CT to ICD-10
Snow Owl is capable to import the SNOMED CT to ICD-10 Cross Map Preview release under development by SNOMED International and the World Health Organization (WHO).
Note that this cross map is still under development by the SNOMED International SNOMED CT to ICD-10 Mapping Workbench project gr
