R00-R09: Symptoms and signs involving the circulatory and respiratory systems

R05: Cough

Cough, categorized under the ICD-10 code R05, is a common symptom that occurs when your body tries to clear your airways of mucus, irritants, or foreign substances. It usually results from conditions affecting the respiratory system including the common cold, influenza, pneumonia, and chronic ailments like asthma, chronic bronchitis, or lung cancer. A cough can be dry or productive, meaning it’s accompanied by phlegm or mucus. Coughing can also be acute, often developing suddenly and for a short time, or chronic, persisting for a long period, usually over eight weeks. Other symptoms may include a runny or stuffed nose, a decrease in appetite, fatigue, and chest pain. Progression of the condition causing the cough will vary depending on its nature. For example, a cough from a respiratory infection will often improve within two weeks, while a chronic cough could indicate a more serious condition requiring medical investigation.
