2009 ICD-9-CM Diagnosis Code 136.9 : Unspecified infectious and parasitic diseases

broad class of diseases whose causative agents may be passed between individuals in many different ways.
Invasion and multiplication of germs in the body. Infections can occur in any part of the body, and can be localized or systemic (spread throughout the body). The germs may be bacteria, viruses, yeast, or fungi. They can cause a fever and other problems, depending on the site of the infection. When the body's natural defense system is strong, it can often fight the germs and prevent infection. Cancer treatment can weaken the natural defense system.
A disorder resulting from the presence and activity of a microbial, viral, or parasitic agent. It can be transmitted by direct or indirect contact. -- 2003 (NCI)
A disorder resulting from the presence and activity of a microbial, viral, or parasitic agent. It can be transmitted by direct or indirect contact. -- 2003
infections or infestations with parasitic organisms; they are often contracted through contact with an intermediate vector, but may occur as the result of direct exposure.
