Postprocedural stenosis of external ear canal, bilateral

This code signifies a narrowing of both external ear canals that develops as a complication following a medical or surgical procedure. This stenosis can impede sound transmission and may lead to conductive hearing loss or recurrent infections.

Use this code when documentation clearly indicates bilateral external ear canal narrowing occurring after an intervention such as otologic surgery, radiation therapy to the head/neck, or prolonged packing of the ear canal. The physician's notes should specify the postprocedural nature and the bilateral involvement.

• Ensure documentation explicitly states "bilateral" involvement; otherwise, use a unilateral code.
• Distinguish from congenital or acquired stenosis not related to a procedure.
• Sequence this code after the primary procedure code if the stenosis is a direct complication of that procedure.
