In the ICD-9 system, a disease may have a cause listed in one chapter, and its manifestations listed in another. For example, Tuberculous meningitis is caused by a bacterial infection, and is therefore listed in Chapter 1, Infectious and parasitic diseases. However, as it results in a disorder of the nervous system, it is also listed in this chapter. An asterisk (*) means that a disease has an underlying cause which can be found elsewhere in the ICD. A code referring to such an underlying cause may be right next to the name, in parentheses, and marked with a dagger symbol of the Times New Roman font (†).
