ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. 

The code set allows more than 14,400 different codes and permits the tracking of many new diagnoses. The codes can be expanded to over 16,000 codes by using optional sub-classifications. 

The WHO provides detailed information about ICD online, and makes available a set of materials online, such as an ICD-10 online browser, ICD-10 Training, ICD-10 online training, ICD-10 online training support, and study guide materials for download. 

The International version of ICD should not be confused with national modifications of ICD that frequently include much more detail, and sometimes have separate sections for procedures. The US ICD-10 Clinical Modification (ICD-10-CM), for instance, has some 93,000 codes. The US also has the ICD-10 Procedure Coding System (ICD-10-PCS), a coding system that contains 76,000 procedure codes that is not used by other countries. 

Work on ICD-10 began in 1983 and was completed in 1992. 

The following is a list of ICD-10 codes. Some 27 countries use ICD-10 for reimbursement and resource allocation in their health system. A few of them have made modifications to ICD to better accommodate this use of ICD-10. The article below makes reference to some of these modifications. The unchanged international version of ICD-10 is used in about 110 countries for performing cause of death reporting and statistics. QUESTIONS:
