Book excerpt: 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.
