About ICD-10
The International Classification of Diseases, 10th Revision, is a system created by the World Health Organization (WHO) to track the prevalence of diseases and other health conditions. In the U.S., the Centers for Medicare and Medicaid Services (CMS) introduced the ICD-10 Clinical Modification (ICD-10-CM) to help healthcare providers classify diseases, symptoms, injuries, and other health-related factors. ICD-10-CM is widely used in the American healthcare system, to improve treatments, minimize medication mistakes, process medical claims, and more.
The International Classification of Diseases, 10th Revision, Procedure Coding System (ICD-10-PCS) is a medical classification coding system for procedural codes. ICD-10-PCS is the official U.S. system used to assign codes to hospital-related procedures.
