The ICD-10 CM is produced by the Centers for Medicare and Medicaid Services (CMS) (see encyclopedic entry: Centers for Medicare and Medicaid Services (CMS)) and the National Center for Health Statistics (NCHS) to code and report medical diagnoses and procedures in the U.S. It is based on the ICD-10, the disease classification system produced by The World Health Organization. In the U.S., the ICD-10-CM replaced the ICD-9 in 2015.  There are more than 70,000 codes in the ICD-10-CM, a significant increase from the ICD-9, which used only 14,000.
