What is the International Classification of Diseases (ICD)?
The International Classification of Diseases (ICD) is an internationally recognized coding system used to classify diseases, symptoms, findings, and external causes of diseases. It is used to code and classify medical diagnoses and procedures in order to provide consistent data for epidemiological studies. The current version is the 10th revision, Clinical Modification (ICD-10-CM), which has been in use since October 2015. ICD codes are used to identify diagnoses and procedures for reimbursement and for tracking healthcare outcomes. They are also used to measure compliance with evidence-based clinical practice guidelines and to track quality of care.
