Procedure concepts with a body structure that has a left/right side
When creating a lateralized procedure concept, two concepts should be created:
- concept for the left side
- concept for the right side
When creating a lateralized procedure concept, if a non-lateralized parent does not exist, then it should be created as well. In other words, do not just create the right and left versions, but also create a concept to represent the laterality-agnostic parent.
For example,
When creating Excision of left mastoid and Excision of right mastoid, also ensure a concept for Excision of mastoid exists.
The acceptable naming pattern for procedures with lateralizable body parts:
- FSN: <Method> of bilateral <anatomical or acquired body structure> (procedure)
- PT: <Method> of bilateral <anatomical or acquired body structure>
- SYN: <Method> of both <anatomical or acquired body structure>
Bilateral procedures should be modeled using two relationship groups, one for each lateralized body structure.
For example,
895470004 | Amputation of bilateral upper limbs (procedure)|
FSN: Amputation of bilateral upper limbs (procedure)
PT: Amputation of bilateral upper limbs
SYN: Amputation of both upper limbs
Figure 1: Stated view of 895470004 |Amputation of bilateral upper limbs (procedure)|
Other synonyms may be added if requested, e.g. Left and right X; Bilateral X, etc.
