Description
Codes that indicate an episode of acute appendicitis
Methodology
These codes were mapped first in snomed using the opencodelist builder. The search terms used were:
- appendicitis
- appendix
- appendicectomy
The codes were discussed by 3 practicing doctors. A summary of this discussion is available on the github issue below. The main points were:
- codes indicating chronic or recurrent appendicitis were removed
- codes indicating a specific cause of appendicitis such as in relation to Crohns disease or amoebic were removed
- codes indicating length of appendix as a specimen after surgery were kept.
These codes were mapped to CTV3 and rechecked. Some extinct codes were found during this mapping and removed.
The final codelist was signed off by the 3 clinicians indicated below.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.
We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
Codes not in the full codelist are in faint grey.
