Definitions for "ICD-10"
International Classification of Diseases, 10th edition. It is the current standard method of coding mortality, and is used on this website. CDO-3: International Classification of Diseases for Oncology, 3rd edition. It is the current standard method of coding cancer incidence, and is used on this website.
ICD-10 is much larger than ICD-9. The number of categories available for the classification is significantly enlarged and further detail is available including ambulatory and managed care encounter information, expanded injury codes, the combination diagnosis/symptoms codes to reduce the number of codes needed to fully describe a condition. The new code is six characters long and incorporates common 4th and 5th digit subclassifications. At present ( ca. mid 1999) ICD-10 is widely used in Europe. In the U.S., however, migration to ICD-10 is complicated by the fact that ICD-9-CM is embedded in hospital billing systems. The goal is to have ICD-10-CM in use for morbidity diagnoses in 2001.
