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.

Questions About R04Overview

Is R04 (Hemorrhage from respiratory passages) a billable code?

No. This is a category header that groups the codes for hemorrhage from respiratory passages, and headers cannot be submitted on claims. Claims for hemorrhage from respiratory passages need a more specific code from this category, such as R04.0, R04.1, and R04.2.

Can R04 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the hemorrhage from respiratory passages is established, that condition takes the principal position instead.
