Classification development


NCCH works with a wide variety of national and international experts to develop content for classification.

Bridge/coding maps

The 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

Classification implementation

The NCCH has assisted a range of overseas countries in adopting the Australian Classification System package including New Zealand and Ireland. Most recently, the NCCH has been supporting Singapore in its migration to ICD-10-AM/ACHI/ACS Sixth Edition and AR-DRG v6.0. We have been involved in 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.

Project management

The 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.

AR-DRG Classification System Development and Refinement Services

Starting 1 July 2013, the University, through the NCCH, with consortium partners the University of Western Sydney and KPMG, will develop the casemix and statistical classification systems in an ongoing capacity, based on clinical and expert advice that builds on the previous investments in the system.

Singapore migration to ICD-10-AM/ACHI/ACS sixth edition and AR-DRG v6.0

The Singapore health system adopted the Sixth Edition of the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) the Australian Classification of Health Interventions (ACHI), the Australian Coding Standards (ACS) and the Australian Refined Diagnosis Related Groups (AR-DRGs) v 6.0, on 1 January 2012. The NCCH through the University of Sydney (UOS) was engaged by the Singapore Ministry of Health in June 2011 to project manage, provide education and mentoring services and expert advice on the coding practices of Singapore health services pre to post migration to the new systems. This project also included the conduct of an educational post-migration coding audit during the latter part of 2012.

Maintenance, Development and Implementation of ICD-10-AM/ACHI/ACS first to seventh editions within Australia

From 1988, NCCH developed and implemented across Australia seven editions of ICD-10-AM/ACHI/ACS. NCCH worked closely with all States and Territories and the professional community, in the development, education, mentoring and implementation.


Coding workshops

In March 2012, the NCCH in conjunction with the Northern Sydney Local Health District prepared and delivered a one day coding continuing education workshop. The workshop included a presentation delivered by Professor Ric Marshall on Activity Based Funding (ABF). The workshop then continued with discussion surrounding the coding of various discharge summaries and clinical record scenarios using ICD-10-AM/ACHI/ACS Seventh Edition.
