D82: Immunodeficiency associated with other major defects
D82.9: Immunodeficiency associated with major defect, unspecified
The immune system protects the body from pathogens and foreign substances. The immune system can also destroy cells in the body that have pathologically changed. The body's immune system is made up of different types of immune cells. Some immune cells can destroy pathogens or foreign bodies themselves. Other immune cells produce certain antibodies.
If your immune system is impaired, you may be unable to properly combat various pathogens. Such pathogens may be bacteria, viruses or fungi. The pathogens can then cause repeated infections, such as respiratory illnesses. With this condition, there are usually other symptoms. For example, various bodily functions may be impaired.
