A18.31 is a billable ICD code used to specify a diagnosis of tuberculous peritonitis. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code A18 is used to code Tuberculosis

Tuberculosis (MTB, TB) is an infectious disease caused by the bacteria Mycobacterium tuberculosis. Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections do not have symptoms, known as latent tuberculosis. About 10% of latent infections eventually progresses to active disease which, if left untreated, kills about half of those infected. The classic symptoms of active TB are a chronic cough with blood-tinged sputum, fever, night sweats, and weight loss. This weight loss was what gave rise to the old term "consumption" for the disease. Infection of other organs can cause a wide range of symptoms.
