Classification development


NCCH works with a wide variety of national and international experts to develop content for health classifications including ICD-10-AM/ACHI/ACS and AR-DRGs.

Maintenance, Development and Implementation of ICD-10-AM/ACHI/ACS within Australia

From 1998, NCCH developed and implemented across Australia the first seven editions of ICD-10-AM/ACHI/ACS and currently, the Ninth Edition. NCCH works closely with all States and Territories and the professional community, in the development, education, mentoring and implementation of each edition.

AR-DRG Classification System Development and Refinement Services

NCCH, with ACCD consortium partners, the University of Western Sydney and KPMG, develop the casemix and statistical classification systems in a continuing capacity, based on clinical and expert advice that builds on the previous investments in the system. The new AR-DRG version 8.0 incorporates ICD-10-AM/ACHI/ACS Ninth Edition and features a complete revision of the case complexity methodology within the DRG classification.

Classification education and implementation

NCCH designs and delivers web-based ICD-10-AM/ACHI/ACS education to facilitate implementation. The Ninth Edition education program is available at this link.

NCCH has assisted a range of overseas countries in adopting the Australian Classification System package including New Zealand and Ireland. NCCH also supported Singapore in its migration to ICD-10-AM/ACHI/ACS Sixth Edition and AR-DRG v6.0. Our involvement included all phases of this project from pre-implementation coder and clinician education workshops, mentoring during the transition phase which commenced on 1 January 2012, post-implementation continuing coder education workshops and a post implementation audit to determine future coder continuing education needs.

NCCH can provide bespoke health classification education and training for industry needs. We develop and deliver specific programs to meet these needs.

Bridge/coding maps

NCCH has had extensive experience in the process of finding an ‘equivalent’ code between two classifications, or editions of the same classification, which enables data users to interpret old and new data across different classifications. Mapping is particularly important for time series data analysis and for grouping data using AR-DRG software as each version is developed on a specific set of disease and intervention codes.

One of the most significant Australian mapping projects was undertaken by the NCCH prior to the introduction of ICD-10-AM within Australia in 1998/1999. As it was known then, the National Coding Centre gathered health information management expertise from within the organisation and established a wide network of external clinical groups to advise and inform development of the classification. These groups comprised clinicians, HIM professionals, and clinical coders. Other mapping projects that have required NCCH involvement include:

  • Maps between ICD-10-AM editions
  • Maps between ICD-9-BPA and ICD-10-AM (First to Fifth Editions)
  • Development of draft ICHI content based on ICD-9-CM Volume 3 and ICPM.
  • Maps between ICD-9 /ICD-9-CM to ICD-10-AM Sixth Edition for specific Singapore code lists
  • Analysis for input of ICD-11 on AR-DRG

Project management

NCCH employs highly specialised and skilled staff. Professional health information managers (HIMs), HIM and coder educators and administrative staff who are all essential for managing projects related to classification development, education and implementation.


Conferences and Coding workshops

In March 2012, the NCCH in conjunction with the Northern Sydney NCCH, with HIMAA co-host the forthcoming 2015 national health information conference with the theme: Diversity, Innovate and Transform. The conference will feature streams covering

  • Health Information Management
  • Clinical Coding Workshops
  • Health Classification, Costing and Funding

The conference provides opportunities for participants to access a broad range of clinical knowledge and applied skills from leading national and international presenters.

NCCH staff continue to attend and present at specific health classification forums in Australia and internationally.
