Epistaxis

This code represents a nosebleed, which is bleeding from the nasal passages. It can range from a minor, self-limiting event to a significant hemorrhage requiring medical intervention. The bleeding originates from the blood vessels within the nasal mucosa.

Use this code when documentation indicates a patient presents with or is diagnosed with a nosebleed. This applies to both acute episodes and recurrent epistaxis. Supporting documentation includes physician notes detailing the occurrence of bleeding from the nose.

• Do not use this code for epistaxis due to trauma; instead, code the specific injury.
• If the cause of the epistaxis is known (e.g., hypertension, anticoagulant use), code the underlying condition first, followed by this code.
• Ensure documentation specifies if the epistaxis is anterior or posterior if that information is available, although it does not change this specific code.
