Codes that indicate an episode of acute appendicitis
These codes were mapped first in snomed using the opencodelist builder. The search terms used were:
The codes were discussed by 3 practicing doctors. A summary of this discussion is available on the github issue below. The main points were:
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.
This definition has been computed by taking the manually created full codelist and converting it to a list of rules that define the codelist.
