ICD-10 is the 10th revision of the International Classification of Diseases. ICD-10 facilitates a statistical classification of disease published by the World Health Organization and is one of several means for reporting procedures performed in acute care facilities.
ICD-10 code sets are used internationally to report patient health conditions. They're also used for mortality reporting in the United States. The U.S. Department of Health and Human Services (HHS) mandated the use of ICD-10 codes in the U.S. on all HIPAA transactions by Oct. 1, 2015, for both reporting and payment of claims.
