ICD-10 Code H61.392 – Other acquired stenosis of left external ear canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.392 – Other acquired stenosis of left external ear canal
What it is
This code identifies an acquired narrowing of the left external ear canal. It means the canal became constricted after birth, not from a congenital defect.
Clinical signs
Patients may have reduced ear canal patency, blocked wax drainage, or conductive hearing complaints. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents acquired stenosis of the left external ear canal. It is appropriate when the narrowing is unilateral and affects the left side. If the note only says “ear canal narrowing” without laterality or acquired status, check documentation.
Do not use for
Do not use this code for congenital ear canal anomalies or for right-sided or bilateral stenosis. Also avoid it when the chart describes cerumen impaction or another temporary obstruction instead of true stenosis.
Coding tip
Confirm both laterality and acquired status in the provider’s note before assigning H61.392.
