Concept Inter-relationships for Concept Inter-relationships for Procedures Procedures
• SNOMED CT uses relationships between concepts to provide logical, computer readable definitions of medical concepts. These relationships, which can be 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 procedures.

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:
Needle biopsy “Is a” (kind of) “Biopsy”

The “Procedure site” RelationshipThe “Procedure site” Relationship
• The “Procedure site” relationship identifies the part of the body acted on by the procedure. For example:
“Lymph node biopsy” (has) “Procedure site” “Lymph node”

The “Direct morphology” RelationshipThe “Direct morphology” Relationship
• The “Direct morphology” relationship identifies the abnormal physical condition that is being directly addressed by the procedure. There is an implicit link between the “method” relationship and the direct morphology. The method acts on the direct morphology. For example:
“Biopsy of cyst” (has) “Method” “Biopsy”
“Biopsy of cyst” (has) “Direct morphology” “Cyst”
Copyright © 2001 College of American Pathologists
The “Method” RelationshipThe “Method” Relationship
• The “Method” relationship identifies the kind of procedure that is being carried out. For example:
“Excision of cyst” (has) “Method” “Excision”
“Catheterization” (has) “Method” “Implantation”
“Serum sodium measurement” (has) “Method” “Observation”

The “Direct Device” RelationshipThe “Direct Device” Relationship
• The “Direct device” relationship identifies the device which involved in the core operation of the procedure. An example of the direct device relationship are as follows:
“Catheterization of artery” (has) “Direct device” “Catheter”
Copyright © 2001 College of American Pathologists
The “Using” RelationshipThe “Using” Relationship
• The “Using” relationship refers to any instrument, equipment or energy that is used to perform the procedure. Examples of the direct device relationship are as follows:
“Needle aspiration biopsy” “Using” “Fine biopsy needle”
“Laser surgery” (has) “Using” “Laser light”
Copyright © 2001 College of American Pathologists
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”
