Other acquired stenosis of right external ear canal

This code signifies a narrowing or obstruction of the right external auditory canal that developed after birth, not due to a congenital anomaly. This acquired stenosis can impede sound transmission and lead to hearing difficulties or recurrent ear infections.

Apply this code when documentation specifies an acquired narrowing of the right external ear canal, such as from trauma, inflammation, or previous surgical intervention. It is appropriate when the laterality is clearly documented as the right ear and the etiology is not congenital.

• Ensure documentation specifies "acquired" and "right ear" to support this code.
• Distinguish from congenital stenosis (Q16.1) or stenosis due to otitis externa (H60.5-).
• Consider an additional code for the underlying cause of the acquired stenosis, if known and documented.
