Australian Refined Diagnosis Related Groups (AR-DRG) Version 10.0

The AR-DRG Version 10.0 (V10.0) was approved by the Pricing Authority in April 2019. It is anticipated that it will be used to price episodes of admitted acute care from 1 July 2020.

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.
