When creating the descriptions for a concept (e.g. a disorder concept) that name an entity such as a body structure, substance or organism, the conventions that are applied for naming the entity in the source hierarchy should be used.
For example,
- 445198003 |Meningitis caused by Haemophilus influenzae type b (disorder)|
...
Concept
...
Concept t 11218009 |Infection caused by Pseudomonas aeruginosa (disorder)|
This concept references the organism hierarchy in the causative agent of 52499004 |Pseudomonas aeruginosa (organism)| and uses that description in the FSN.
- 143491000146106 |Felis catus protein (substance)|
448169003 |Felis catus (organism)| has a preferred term of “Domestic cat”. As a result a related concept in the Substance hierarchy, 143491000146106 |Felis catus protein (substance)| has a preferred term of “Domestic cat protein”.
Concept t 337311000119101 |Blepharochalasis of left upper eyelid (disorder)|
This concept references the body structure hierarchy in the finding site of |Structure of left upper eyelid (body structure)| and uses "left upper eyelid" in the FSN.
Concept t 12081931000119106 126885006 |Burn of left eye region Neoplasm of urinary bladder (disorder)|
This concept references the body structure hierarchy in the finding site of
...
89837001 |Urinary bladder structure (body structure)| and uses "
...
urinary bladder" in the FSN and PT.

The term bladder must be include urinary to distinguish from gallbladder in order to aid in translation. Urinary bladder must be used in both the fully specified name and preferred term. |
The descriptions should be context neutral for these foundation hierarchies. Where context is explicit for a disease or procedure, the preferred term from foundation hierarchies can be used instead. For example, procedure CT of abdomen indicates that the context of CT imaging is cross-sectional. The procedure site should be modeled with the cross-sectional abdomen. However, it is not necessary to change 'Computed tomography of abdomen (procedure)' to 'Computed tomography of cross-sectional abdomen (procedure)'. It is the same reason for the preferred term 'CT of abdomen'.
