Acquired stenosis of ext ear canal secondary to trauma, bi

This diagnosis code signifies a narrowing of both external ear canals that developed after a traumatic injury. This acquired stenosis can impede sound transmission and may lead to recurrent infections or hearing loss. It is distinct from congenital or inflammatory causes of ear canal narrowing.

Apply this code when documentation clearly states bilateral external auditory canal stenosis resulting from a specific traumatic event, such as a fracture, laceration, or burn to the ear. Supporting documentation should detail the traumatic etiology and the subsequent development of the stenosis affecting both ears.

• Ensure the documentation explicitly links the stenosis to a traumatic event and specifies bilateral involvement.
• Differentiate from H61.32- (stenosis due to inflammation) or H61.33- (stenosis due to other acquired conditions).
• Consider sequencing this code after an acute injury code if the stenosis is a direct sequela and still being treated.
