WA Clinical Coding Authority

Clinical coding is the translation of written clinical documentation about patient care into code format. For example, acute appendicitis is represented by the code 'K35.8'.

A standardised classification system, The International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM), is applied in all Australian acute health facilities.

It is based on the World Health Organisation ICD-10 system, updated with the Australian Classification of Health Interventions (ACHI), Australian Coding Standards (ACS) and ICD-O-3 (International Classification of Diseases for Oncology, 3rd edition).

What does a Clinical Coder do?

A clinical coder is responsible for abstracting relevant information from the medical record and deciding which diagnoses and procedures meet criteria for coding as per Australian and WA Coding Standards. The coder then assigns codes for these diagnoses and procedures based on ICD-10-AM conventions and standards.

Clinical coding is a specialised skill requiring excellent knowledge of medical terminology and disease processes, attention to detail, and analytical skills.

What is coded information used for?

The assigned codes and other patient data are processed by grouper software to determine a Diagnosis Related Group (DRG) for the episode of care, which is used for funding and reimbursement. This process allows hospital episodes to be grouped into meaningful categories, helping us to better match patient needs to health care resources. Other common uses of coded data:
  • Clinical research and audits
  • Resource allocation
  • Health services planning
  • Statistics
  • Epidemiological studies
  • Clinical benchmarking
  • Education
Western Australian Clinical Coding Advisory Group

The Western Australian (WA) Coding Committee was officially retired in 2012, replaced by the WA Clinical Coding Advisory Group. The group consists of a cross-section of the WA coding community, including clinical coders and coding managers with substantial experience and from a variety of hospitals. The primary function of the group is to review and endorse decisions for resolution of ICD-10-AM coding queries. The decisions and meeting dates are published below.

Along with the current decisions made by the WA Clinical Coding Advisory Group, previous coding query decisions made by the WA Coding Committee are enforceable until the decision is officially retired.
