ICD-10 Code H61.313 – Acquired stenosis of external ear canal secondary to trauma, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.313 – Acquired stenosis of external ear canal secondary to trauma, bilateral
What it is
This code identifies narrowing of both external ear canals that developed after trauma. It means the ear canal openings are abnormally tight because of injury-related scarring or tissue change.
Clinical signs
Patients may have reduced ear canal patency, difficulty examining the tympanic membrane, or conductive hearing complaints. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral acquired stenosis of the external ear canal and links it to prior trauma. It fits cases where narrowing is a sequela of injury, surgery, or other documented traumatic cause. Confirm that both sides are involved.
Do not use for
Do not use it for congenital ear canal narrowing or for unilateral stenosis. Check documentation if the cause is not clearly traumatic or if the condition is described with a different etiology.
Coding tip
Verify both laterality and the documented traumatic origin before assigning H61.313.
