An ICD-10 code is a standardized alphanumeric code for a disease, diagnosis, symptom, or procedure, used globally for mortality and morbidity data. It is a classification system published by the World Health Organization (WHO) and is used by healthcare providers for patient records and for insurance claim processing. The United States also uses a clinical modification, ICD-10-CM, and an inpatient procedure system, ICD-10-PCS.
