procedure/targetSiteCode may be used to encode the specific anatomic focus, and is not necessarily identical to documentationOf/serviceEvent/code/translation used for anatomic region in the CDA header. This may be derived from Body Part Examined (0018,0015), as mapped to SNOMED codes in Annex L “Correspondence of Anatomic Region Codes and Body Part Examined Defined Terms” in PS3.16, or from Anatomic Region Sequence (0008,2218).

COND: The qualifier element for laterality SHALL be present if the targetSiteCode represents a paired body part and laterality is not pre-coordinated in the targetSiteCode.
