Acquired stenosis of r ext ear canal sec to inflam and infct

This code signifies a narrowing of the right external auditory canal that developed after birth, specifically caused by inflammatory and infectious processes. This stenosis can impede sound transmission and lead to recurrent otitis externa or hearing loss.

Apply this code when documentation clearly indicates an acquired, non-congenital stricture of the right external ear canal resulting from inflammation (e.g., chronic otitis externa) and/or infection. The physician's notes should specify the laterality and the etiology.

• Ensure documentation specifies "acquired" and not congenital stenosis.
• Look for explicit mention of inflammation and/or infection as the cause.
• Do not confuse with codes for congenital stenosis or stenosis due to trauma or other causes.
