Acquired stenosis of r ext ear canal secondary to trauma

This code describes a narrowing or obstruction of the right external auditory canal that developed as a result of an injury. This stenosis can impede sound transmission and may lead to conductive hearing loss or recurrent ear infections.

Use this code for patients presenting with documented narrowing of the right external ear canal directly attributed to a traumatic event, such as a laceration, fracture, or burn to the ear. Documentation should clearly link the stenosis to a specific past or recent trauma.

• Ensure the documentation specifies the right ear and explicitly states the stenosis is acquired and secondary to trauma.
• Distinguish from congenital stenosis (Q16.1) or stenosis due to inflammation/infection (H61.32-).
• Consider an external cause code (V00-Y99) if the specific traumatic event is still relevant and documented.
