International Classification of Diseases

9th Revision (ICD-9)


International Classification of Diseases (ICD-9) is designed for the classification of morbidity and mortality information for statistical purposes, and for the indexing of hospital records by disease and operations, for data storage and retrieval. To code accurately, it is necessary to have a working knowledge of medical terminology and to understand the characteristics, terminology, and conventions of the ICD-9-CM. Transforming verbal descriptions of diseases, injuries, conditions, and procedures into numerical designations (coding) is a complex activity and should not be undertaken without proper training.   Originally, coding was accomplished to provide access to medical records by diagnoses and operations through retrieval for medical research, education, and administration.
