B22.7: HIV disease resulting in multiple diseases classified elsewhere

HIV disease resulting in multiple diseases classified elsewhere, coded as B22.7 in the ICD-10, is a condition where an individual with the human immunodeficiency virus (HIV) develops one or more other diseases as a consequence of their weakened immune system. HIV is a virus that slowly attacks the immune system, our body's natural defense against illnesses. As the virus progresses untreated, the immune system becomes less able to fight off infections and diseases. This vulnerability leads to an increased risk of contracting various other diseases, including cancers, brain disorders, cardiovascular disease, and a vast array of infections. Symptoms of these secondary diseases vary greatly depending on the specific condition but can often include fever, fatigue, swelling, pain, cognitive changes, and many other signs. Without treatment, this combination of HIV and additional health problems can become severe and life-threatening.
