J96: Respiratory failure, not elsewhere classified

J96.1: Chronic respiratory failure

Chronic respiratory failure, classified by ICD-10 code J96.1, is a long-term medical condition where the respiratory system is unable to function effectively. This failure results in insufficient oxygen levels, known as hypoxemia, raised levels of carbon dioxide, or hypercapnia, or sometimes both in the blood. The condition can be triggered by diseases that affect the lung's structure, such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, or pulmonary fibrosis. Symptoms mainly include shortness of breath, rapid breathing, confusion, lethargy or even unconsciousness in severe cases. It's a progressive condition that varies in severity, but it generally produces increased fatigue and reduced exercise tolerance over time, hence profoundly affecting the quality of life. The condition can further compromise other systems in the body, particularly cardiovascular and neurological ones, if not carefully managed.
