Conversion Of Neoplasms By Topography And Morphology From The International Classification Of Diseases For Oncology Second Edition Icd O 2 To The International Statistical Classification Of Diseases And Related Health Problems 10th Revision Icd 10

International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), which is adapted from ICD-9, is used for coding morbidity in all hospitals, now in the 4th edition. It must be used for coding diagnoses which submit claims for third party payment. There are very slight differences between the two books in the Neoplasm Chapter, but the differences are shown in this book and are compiled in the last section of this book. The Topography Section of ICD-O-2 is based on the malignant neoplasms section, categories C00-C80 of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10), so there is a close relationship between that and ICD-10. The Morphology Section of ICD-O-2 is a revised and expanded version of the Morphology Section of the ICD-O-1. This conversion has been prepared to help those who wish to compare or convert diagnoses coded according to ICD-O-2 with diagnoses coded according to the ICD-9-(CM). For example, a cancer registry may code its diagnoses by ICD-O-2, whereas the record room in the same hospital referring cases to the cancer registry may have used the ICD-9-(CM) to code its case material.

This edition of ICD-O, the standard tool for coding diagnoses of neoplasms in tumour and cancer registrars and in pathology laboratories, has been developed by a working party convened by the International Agency for Research on Cancer / WHO. ICD-O is a dual classification with coding systems for both topography and morphology. The book has five main sections. The first provides general instructions for using the coding systems and gives rules for their implementation in tumour registries and pathology laboratories. Section two includes the numerical list of topography codes, which remain unchanged from the previous edition. The numerical list of morphology codes is presented in the next section, which introduces several new terms and includes considerable revisions of the non-Hodgkin lymphoma and leukaemia sections, based on the WHO Classification of Hematopoietic and Lympoid Diseases. The five-digit morphology codes allow identification of a tumour or cell type by histology, behaviour, and grade. Revisions in the morphology section were made in consultation with a large number of experts and were finalised after field-testing in cancer registries around the world. The alphabetical index gives codes for both topography and morphology and includes selected tumour-like lesions and conditions. A guide to differences in morphology codes between the second and third editions is provided in the final section, which includes lists of all new code numbers, new terms and synonyms added to existing code definitions, terms that changed morphology code, terms for conditions now considered malignant, deleted terms, and terms that changed behaviour code.
