B22: Human immunodeficiency virus [HIV] disease resulting in other specified diseases
B22.1: HIV disease resulting in lymphoid interstitial pneumonitis
HIV disease resulting in lymphoid interstitial pneumonitis is a medical condition where the human immunodeficiency virus (HIV) has led to changes in the lungs known as lymphoid interstitial pneumonitis. HIV is a virus that attacks the body's immune system, making it harder to fight off infections and diseases. Lymphoid interstitial pneumonitis, on the other hand, is a rare lung disease usually associated with conditions that affect the immune system. It is characterized by inflammation and swelling of the small air sacs or the tissue around them in the lungs. Common signs of this condition may include cough, shortness of breath, and fatigue. Over time, the combination of these two conditions can lead to serious, and potentially life-threatening complications, particularly if the immune system becomes significantly weakened and the lung condition worsens.
