B20-B24 Disease caused by human immunodeficiency virus [HIV]
Note. The four-digit subheadings B20-B23 are offered for optional use in cases where it is impossible or impractical to use multi-reason coding in order to identify specific states.

B90-B94 Consequences of infectious and parasitic diseases
Note: these headings should be used to refer to the states listed under A00-B89 as the cause of the consequences. The term "consequences" includes the states specified as such, as well as the residual phenomena of diseases classified in the above-mentioned headings, if it is obvious that the causative disease is currently absent. The use of this category should be guided by the recommendations and rules for coding morbidity and mortality, cited in v.2.
B95-B97 Bacterial, viral and other infectious agents
Note: these headings should not be used for primary encoding. They are intended to be used as additional codes when it is advisable to identify pathogens classified elsewhere.
B99 Other infectious diseases
B99 Other and unspecified infectious diseases
