R04.8: Haemorrhage from other sites in respiratory passages

Haemorrhage from other sites in respiratory passages, as the name suggests, refers to bleeding that occurs from various parts within the respiratory system, excluding the lungs and bronchi. This condition may present due to trauma, infections, tumors, or other underlying conditions that affect the integrity of the blood vessels present in these passages. Common symptoms may include coughing up blood, difficulty in breathing, chest pain, hoarseness, and in severe cases, low blood pressure due to significant blood loss. The progress and effect of this condition can vary and largely depend on the severity of the bleed and the underlying cause. The condition primarily affects the respiratory system but in severe cases, it might also have an impact on the circulatory and immune systems. It's important to note that this condition is often a symptom of an underlying disease that may need to be diagnosed and treated to stop the bleeding.
