Diabetes Ketoacidosis - SNOMED (DKA - unspecific)

Coding system
Codelist ID


This lists contains codes used to identify people who may have had diabetes ketoacidosis (DKA). This list was conceived to identify DKA in a specific group of patients in a specific time period, therefore we have been permissive in including unspecific codes which may not be suitable for all studies.


Using the OpenCodelists builder we used search terms

  • dka
  • ketoacidosis
  • acidosis

Further discussion about further inclusion and exclusion can be seen in GitHub.
