Z20: Contact with and exposure to communicable diseases
Z20.7: Contact with and exposure to pediculosis, acariasis and other infestations
Having contact with specific pathogens does not necessarily mean that you will get sick. Whether you get sick and which symptoms you develop depends on several factors. Among these for instance are how long you had contact with the pathogens or how many pathogens you were exposed to. Another factor is how well your own immune system works.
If very small organisms such as lice or mites colonize the body, the skin will often become inflamed. Your skin will often be itchy and you will usually scratch it. It is also possible sometimes for internal organs such as the lungs or intestines to be damaged.
