About

The Independent Hospital Pricing Authority (IHPA) was established in 2011 as part of the National Health Reform Agreement. At this time IHPA took over responsibility for the development and licensing of the following classifications:

  • International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM)
  • Australian Classification of Health Interventions (ACHI)
  • Australian Coding Standards (ACS)
  • Australian Refined Diagnosis Related Groups (AR-DRGs)

The Australian Consortium for Classification Development was contracted to manage the development of ICD-10-AM/ACHI/ACS from 2013 to 2019. As of 1 July 2019 ICD-10-AM/ACHI/ACS development has been brought within IHPA.

The IHPA Australian Classification Exchange (ACE) is a portal for registered users which provides access to the following:

  • New edition education
  • Published coding queries
  • Coding query submission (nominated representatives only)
  • Submission of public submissions (ICD-10-AM/ACHI/ACS and AR-DRG)
