Emergency Department ICD-10-AM (Tenth Edition) Principal Diagnosis Short List

In 2013 IHPA initiated a review to assess long term options for classification of emergency care services for activity based funding in Australia.

A major objective of the approach to classifying emergency care services in Australia is to drive efficiency and effectiveness of these services through pricing and funding in conjunction with the collection of underlying data that supports clinical care and other uses such as quality improvement, epidemiological monitoring and health services research.

The review recommended development of a new Emergency Care Classification to replace the Urgency Related Groups (URGs) and Urgency Disposition Groups (UDGs) given the lack of support for the ongoing use of triage and the strong interest in moving to a more diagnosis based classification. There was also strong support for a more nationally consistent approach to principal diagnosis reporting in the Emergency Department to underpin the new Australian Emergency Care Classification.

The national short list replaces current inconsistencies whereby states and territories have developed localised short lists and variously report principal diagnosis using Systematized Nomenclature of Medicine – Clinical Terms (SNOMED CT) and various editions of International Statistical Classification of Diseases and Related Health Problems – Tenth Revision – Australian Modification (ICD-10-AM) or the International Classification of Diseases – Ninth Revision – Clinical Modification (ICD-9-CM).

The short list was developed in 2015 using classification principles endorsed by IHPA’s Emergency Care Advisory Working Group and in consultation with key health sector stakeholders. It was subject to a public consultation in August 2015. Following which, the short list underwent further independent refinement and review by two Health Information Managers. The Emergency Department ICD‑10‑AM Tenth Edition Principal Diagnosis Short List was endorsed by the national data governance committee in November 2018 for inclusion in the 2018‑19 Non‑admitted Patient Emergency Department Care National Minimum Data Set (NAPEDC NMDS).

IHPA has developed a range of supporting material to assist stakeholders in implementing and using the short list. The short list and associated components are provided below and will be updated periodically by IHPA for compatibility with the latest ICD-10-AM edition.

Please note, in addition to the documents published below, IHPA has also developed a mapping file between the short list and full ICD‑10‑AM code set. However, as the short list mapping file contains the full ICD-10-AM code set, it is not available through the IHPA website as it is licensed material. This mapping file can be provided to stakeholders upon request, following proof that the stakeholder holds the required licensing agreements for ICD‑10‑AM. 

Any enquiries related to the short list should be directed to (enquiries.ihpa [at] ihpa.gov.au).
