The Australian Refined Diagnosis Related Groups (AR-DRGs) is a classification system, which provides a clinically meaningful way to relate the number and type of patients treated in a hospital to the resources required by the hospital. AR-DRGs group patients with similar diagnoses requiring similar hospital services. 

AR-DRG Version 10.0 was approved by the Pricing Authority in April 2019 and was implemented from 1 July 2020 to price admitted acute episodes of care. AR-DRG Version 10.0 supersedes AR-DRG Version 9.0.

The development process has used clinical input, statistical analysis and extensive consultation with clinicians, jurisdictions and other health sector stakeholders.  A major focus for this version was to review the complexity model, specifically the diagnosis exclusions, and its overall stability. Further detail on what was reviewed for AR-DRG Version 10.0 can be found in the Final Report. 

The Definitions Manual for AR-DRG Version 10.0 is published as a set of three volumes which contain the following products:

  • Volume 1: DRGs A13A–I80Z
  • Volume 2: DRGs J01A–Z66Z
  • Volume 3: Appendices

It is anticipated that AR-DRG Version 11.0 will supersede AR-DRG Version 10.0 and be applicable for separations from 1 July 2023.

The AR-DRG Version 11.0 Definitions Manual will be available to purchase from mid-July 2022 from the Lane Print website
