C.4.3 Content Item Mapping

Each Content Item immediately subsidiary to a section CONTAINER shall be mapped to the corresponding entry level template, and shall be included subsidiary to the associated CDA section or subsection. This is in addition to its rendering in the section/text narrative block.

Coded concepts that are encoded in the SR using with the Coding Scheme Designator "SRT" shall be mapped to the equivalent SNOMED CT code. Mappings for value sets invoked in both SR and CDA are provided in PS3.16.

C.4.3.1 Coded Observations

SR CODE Content Items shall be mapped to Coded Observation entries.

The CODE observations in TID 2002 do not specifically include finding site, laterality, and topographical modifiers, but these modifiers are not forbidden in the template, and may be present in a SR SOP Instance being transformed to CDA.
