Postprocedural stenosis of unspecified external ear canal

This code signifies a narrowing or obstruction of the external auditory canal that occurs as a complication following a medical procedure. The specific procedure causing the stenosis is not identified, nor is the laterality of the ear affected.

Apply this code when documentation clearly indicates postprocedural stenosis of the external ear canal, but the operative event leading to the stenosis is unspecified. This is appropriate when the provider notes "post-surgical ear canal stenosis" without further detail on the surgery or the affected ear.

• Ensure documentation specifies "postprocedural" to differentiate from congenital or acquired non-procedural stenosis.
• Avoid using this code if the specific procedure or laterality is known; instead, use a more specific code from the H95.81 subcategory.
• Always sequence this code after the primary reason for the encounter, unless the stenosis is the primary reason for treatment.
