WHO's International Classification of Diseases has been fully updated for the third time. Originally published in the early 1990s, this 10th edition (ICD-10) now incorporates all edits and updates up to the end of 2010. In addition, the numbering system has changed and now clearly indicates the year that the updates were incorporated.
The ICD is the international standard diagnostic classification for all general epidemiological purposes, many health management purposes and clinical use. These include analysis of the general health situation of population groups and monitoring the incidence and prevalence of diseases, as well as other health problems with respect to variables such as the characteristics and circumstances of the individuals affected, reimbursement, case-mix, resource allocation, quality, patient safety, and guidelines.
ICD is used for health information purposes in public health, primary, secondary and tertiary care settings. In particular, it is used to classify diseases, accidents, reasons for encounter, and other health problems recorded on many types of health and vital records including death certificates. In addition to facilitating the storage and retrieval of diagnostic information for clinical, epidemiological and quality purposes, the resulting records form the basis for compiling national mortality and morbidity statistics by WHO Member States. ICD serves as a language-independent framework for classification of diseases and has been translated into more than 40 languages.
Changes in this new edition include:
Volume 1 - extensive corrections for Lymphomas and Leukaemias in the neoplasms chapter, clarification and added details for some maternal conditions and various edits.
Volume 2 - clarification of definitions and rules around maternal cases, causes of pneumonia and extensive editing of the unchanged rules for coding neoplasms in causes of death.
Volume 3 - updated to reflect the new terms and changes in Volume 1.
