The U.S. Department of Health and Human Services has announced that the compliance date of International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) has been delayed for a year. ICD-10-CM is a revised system to classify and code all diagnoses, symptoms and procedures recorded in conjunction with hospital care in the US. It contains 68,000 diagnostic codes, a significant increase to the 13,000 found in the current ICD-9-CM. The United States was set to begin using ICD-10 on October 1, 2013, prior to the announcement. The new deadline is October 1, 2014.
