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.
