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

This code signifies a narrowing of the left external auditory canal that developed after birth, specifically caused by inflammatory processes and/or infections. This acquired stenosis can lead to hearing impairment, ear pain, and recurrent infections due to impaired drainage.

Apply this code when documentation clearly indicates a non-congenital narrowing of the left external ear canal resulting from inflammation (e.g., otitis externa, cellulitis) or infection. Supporting documentation should specify the laterality and the underlying inflammatory/infectious etiology.

• Ensure documentation specifies "left" ear and an "acquired" (not congenital) etiology.
• Code the underlying inflammation or infection first, if still active and being treated.
• Distinguish from H61.31- (acquired stenosis of right external ear canal) and H61.33- (bilateral).
