Concept Inter-relationships for Concept Inter-relationships for Disorders Disorders
• SNOMED CT uses relationships between concepts to provide logical, computer readable definitions of medical concepts. These relationships, which can be either hierarchical or non-hierarchical, enable health data to be re-used for decision support, outcomes analysis and clinical research. Follow this link to see the relationship types applicable to finding and disorders.

The “Is a” RelationshipThe “Is a” Relationship
• The “Is a” relationship is used to create a hierarchical relationships between concepts, relating specific concepts to a more general category. For example:
“Ischemic heart disease” “Is a” (kind of) “Myocardial disease”

The “Finding site” RelationshipThe “Finding site” Relationship
• The “Finding site” relationship identifies the part of the body affected by the specific disorder or finding. For example:
“Myocardial Infarction” (has) “Finding site” “Myocardium”

The “Causative agent” RelationshipThe “Causative agent” Relationship
• The “Causative agent” relationship identifies the direct cause of the disorder or finding. The causative agent is the bacterium, virus, toxin or environmental agent that causes the disorder. For example:
“Rheumatic heart disease”
(has) “Causative agent”
“Streptococcus”

The “Associated morphology” The “Associated morphology” RelationshipRelationship
• The “Associated morphology” relationship identifies the abnormal physical condition that is characteristic of a given disorder or finding. For example:
“Acute MI” (has) “Associated morphology” “Acute infarct”

The “Laterality” RelationshipThe “Laterality” Relationship
• The laterality relationship specifies the side of the body that applies to an anatomy concept. Procedures, findings and disorders can have laterality by qualifying their site (procedure-site or finding-site). For example:
“Left kidney” (has) “Laterality” “Left”
“Cyst of left kidney” (has) “Finding site” “Left Kidney”
“Biopsy of left kidney” (has) “Procedure site” “Left Kidney”
