About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Nose Injuries and Disorders

Your nose is important to your health. It filters the air you breathe, removing dust, germs, and irritants. It warms and moistens the air to keep your lungs and tubes that lead to them from drying out. Your nose also contains the nerve cells that help your sense of smell. When there is a problem with your nose, your whole body can suffer. For example, the stuffy nose of the common cold can make it hard for you to breathe, sleep, or get comfortable.
