Postprocedural stenosis of left external ear canal

This code describes a narrowing or obstruction of the left external auditory canal that occurs as a complication following a medical procedure. This stenosis can result from scarring, inflammation, or other tissue changes induced by prior surgical intervention or other invasive treatments involving the ear canal.

Use this code when documentation clearly indicates a postprocedural narrowing of the left external ear canal. This typically applies after procedures such as tympanoplasty, mastoidectomy, or removal of foreign bodies/tumors from the ear canal. Documentation should specify the laterality (left) and the postprocedural etiology.

• Ensure documentation explicitly states "postprocedural" to differentiate from congenital or acquired non-postprocedural stenosis.
• Always confirm laterality (left ear) as there are distinct codes for right and bilateral involvement.
• Consider sequencing this code after a code for the underlying condition or complication that necessitated the initial procedure, if applicable and still active.
