R04.9: Haemorrhage from respiratory passages, unspecified

Haemorrhage from respiratory passages, unspecified (ICD-10 code R04.9), refers to bleeding that originates within the respiratory system. This condition can take place anywhere along the respiratory tract, which includes the nose, throat, voice box (larynx), windpipe (trachea), and lungs. The exact cause can be varied, ranging from minor irritations such as nosebleeds or chronic cough, to more serious conditions like lung disease or cancer. Symptoms often include coughing up blood (hemoptysis), difficulty breathing, or potentially, blood appearing in the nostrils, depending on the location of the bleeding. While this condition can be alarming, it is not always indicative of a severe condition. However, it could suggest an underlying severe respiratory issue and a thorough medical evaluation is generally recommended to determine the cause and appropriate management.
