The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) is a revision of the ICD-9-CM system. Physicians and other providers use the system to classify and code all diagnoses, symptoms, and procedures recorded in conjunction with hospital care in the US.
ICD-10-CM, like ICD-9-CM, is based on the International Classification of Diseases, which is published by the World Health Organization (WHO). The International Classification of Diseases uses alphanumeric codes to identify known diseases and other health issues. According to WHO, the ICD helps with the storage and retrieval of diagnostic information and in the compilation of national mortality and morbidity statistics. The ICD-10-CM revision has more than 68,000 diagnostic codes, compared to the 13,000 found in ICD-9-CM. The revision also includes twice as many categories, and it introduces alphanumeric category classifications for the first time.
The United States was set to begin using ICD-10 on Oct. 1, 2013. In early 2012, the U.S. Department of Health and Human Services announced its intention to delay the compliance deadline to an unspecified date.
On August 24, Health and Human Services Secretary Kathleen Sebelius announced a rule finalizing a one-year delay in the complaince date for ICD-10 codes. The new deadline for ICD-10 is October 14, 2012.
