While WHO manages and publishes the base version of the<unk> , several member states have modified it to better suit their needs. In the base classification, the code set allows for more than 14,000 different codes and permits the tracking of many new diagnoses compared to the preceding<unk> -9. Through the use of optional sub-classifications,<unk>  allows for specificity regarding the cause, manifestation, location, severity, and type of injury or disease. The adapted versions may differ in a number of ways, and some national editions have expanded the code set even further; with some going so far as to add procedure codes.<unk> -CM, for example, has over 70,000 codes. The WHO provides detailed information regarding the<unk>  via its website – including an<unk>  online browser and<unk>  training materials.
