ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification)


The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a revision to the ICD-9-CM system used by physicians and other health care providers to classify and code all diagnoses, symptoms and procedures recorded in conjunction with hospital care in the United States.

Like ICD-9-CM, the ICD-10-CM is based upon the International Classification of Diseases, which is published by the World Health Organization (WHO) and which uses unique alphanumeric codes to identify known diseases and other health problems. According to WHO, the ICD assists in the storage and retrieval of diagnostic information and in the compilation of national mortality and morbidity statistics.

The ICD-10-CM revision includes more than 68,000 diagnostic codes, compared to 13,000 in ICD-9-CM. In addition, ICD-10-CM includes twice as many categories and introduces alphanumeric category classifications for the first time.

Preparation for ICD-10 varies widely among health care providers.

American Medical Association opposes implementing ICD-10.
