Procedure code (ACHI 10th edn) NNNNN-NN

Source and reference attributes

ACHI was developed by the National Centre for Classification in Health (NCCH) at the University of Sydney. During the development, the NCCH was advised by members of the NCCH Coding Standards Advisory Committee (CSAC) and the Clinical Classification and Coding Groups (CCCG), consisting of expert clinical coders and clinicians nominated by the Clinical Casemix Committee of Australia.

In 2010, the National Casemix and Classification Centre (NCCC) at the University of Wollongong assumed responsibility for ACHI development and maintenance. NCCC developed the 2012 version of ACHI, released for implementation in 2013.

In 2013, the NCCH at the University of Sydney once again assumed responsibility for ACHI development and maintenance, as part of a consortium under the name of the Australian Centre for Classification Development (ACCD). The ACCD comprises the NCCH, the University of Western Sydney and KPMG.

From 1 July 2014, all ICD-10-AM/ACHI/ACS and AR-DRG related products are available for purchase from the Independent Hospital Pricing Authority (IHPA). For further information, contact the IHPA via the following email address:
