The goal of the Consultation and review of the AR-DRG and ICD-10-AM/ACHI/ACS Classification Systems report was to review the end-to-end development processes, implementation arrangements and user needs in developing and implementing updates to the following classifications, now and into the future:
Following the completion of the 2016 Inter-Rater Reliability (IRR) study to test the consistency of clinician application of the mental health phase of care, the poor to fair reliability outcome led to the commencement of the refinement project.
The Independent Hospital Pricing Authority (IHPA) has developed the Australian Mental Health Care Classification Pricing Feasibility Report 2020–21 to provide an overview of the process undertaken by IHPA to shadow price admitted mental health services using the Australian Mental Health Care Classification (AMHCC) Version 1.0.
The ICD-10-AM/ACHI/ACS classification system is comprised 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)
ICD-10-AM/ACHI/ACS Eleventh Edition is published as a set of five volumes which contain the following products:
The Independent Hospital Pricing Authority (IHPA) is currently developing a new classification for non-admitted care - the Australian Non-Admitted Care Classification (ANACC) - in response to the recommendations of public consultations in 2013 and 2014 on non-admitted care classification.
This document provides background to the development of the new classification, explains the data elements and collection protocols, reporting requirements, and how the data is grouped.
The Inter-rater reliability study final report was approved by the Pricing Authority in April 2017. The primary aims of the study were to test the inter-rater reliability of the mental health phase of care instrument, gather information about the clinicians' views of the mental health phase of care, identifying ways of increasing the clarity to reduce the ambiguity of the instrument, and to provide recommendations on how the instrument may be refined.
AR-DRG Version 9.0 Final Report
AR-DRG Version 9.0 was approved by the Pricing Authority in November 2016. Development of Version 9.0 was finalised following clinical and statistical analysis and in consultation with clinicians, jurisdictions and other health sector stakeholders. It has been used to price admitted acute episodes of care from 1 July 2018.
The AR-DRG Version 9.0 final report details the changes and rationale for the refinement process.
The purpose of this costing study was to undertake a Teaching, Training and Research (TTR) cost and activity data collection at a representative sample of Australian hospitals and produce costed data to inform the development of a TTR classification.
This document provides information for clinicians to enable them to assess phases accurately when applying the new concept of mental health phase of care.
This document describes the Australian Mental Health Care Classification and the process IHPA has undertaken to develop the new classification.
The Independent Hospital Pricing Authority is committed to providing the Australian health care industry with a nationally consistent method of classifying all types of patients, their treatment and associated costs. Consequently, resources continue to be devoted to the ongoing development of a Diagnosis Related Groups (DRG) classification system based on local clinical practice.
This report presents the results of phase one of the project to develop Australian Refined Diagnosis Related Groups (AR-DRG)1 Version (V) 8.0. This phase focuses on the case complexity component of the classification that has not been reviewed for many years
