ICD-10-AM 4th Ed is composed of 5 volumes:

1. Tabular List of Diseases. The tabular list of diseases contains the disease classification itself at the three, four and five character levels. Two appendices are specified: Morphology of neoplasms; and Special tabulation lists for mortality and morbidity.
2. Alphabetic Index of Diseases. The index to diseases consists of three sections: Section I is the index of diseases, syndromes, pathological conditions, injuries, signs, symptoms, problems and other reasons for contact with health services. Section II is the index of external causes of injury. The terms included here are not medical diagnoses but descriptions of the circumstances in which the violence occurred. Section III is the index of drugs and other chemical substances giving rise to poisoning or other adverse effects (also referred to as the Table of drugs and chemicals).
3. Tabular List of Procedures (ACHI). The tabular list of procedures contains the procedure classification itself. Two appendices are specified: Mapping table; and ACHI codes listed in numerical order.
4. Alphabetic Index of Procedures (ACHI). The index of procedures contains many procedure terms which do not appear in Volume 3.
5. Australian Coding Standards. The Australian Coding Standards contain the national standards developed by the NCCH which provide guidance in the application of ICD-10-AM codes.
