Topic: ConceptMap mapping to multiple CodeSystems

Shamil Nizamov (Dec 09 2020 at 17:38):

Am I correct that to specify which code system the target concept uses in case the target value set comprises of multiple code systems (in the ConceptMap resource), I can use ConceptMap.element.target.dependsOn.codeSystem?

It would be nice to have an example that shows mapping from the source value set to a target value set where the latter uses concepts from multiple code systems (e.g., codes and NullFlavour values).

you would use multiple groups. dependsOn is something else altogether.

if you have a logical mapping, I can make it into a conceptMap for you

@Grahame Grieve I'm looking at using ConceptMap for mapping from ICD-10-CM to CCS, where one ICD-10-CM diagnosis may have multiple CCS groups (primary, secondary, etc). Using the group structure, do I repeat the full group? Or the group.target?

Here you can see a row, where the first column is an ICD-10 code and then there is a 'Default CCSR CATEGORY IP' column and an optional ''CCSR CATEGORY 2' column.
