The topics covered in this fact sheet include:

  • collecting information on patients in hospital
  • national data collection for admitted patient care
  • what is an additional diagnosis?
  • when is an additional diagnosis assigned?
  • resources to support assigning additional diagnoses
  • designing ACS 0002 Additional diagnoses for Twelfth Edition
  • ACS 0002 pilot exercise used to refine usability
  • structure of ACS 0002 Additional diagnoses
  • navigating additional diagnoses criteria.
