ICD-10 Code H61.311 – Acquired stenosis of right external ear canal secondary to trauma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.311 – Acquired stenosis of right external ear canal secondary to trauma
What it is
This code identifies narrowing of the right external ear canal that developed after trauma. It describes an acquired, not congenital, condition affecting the outer ear passage.
Clinical signs
Patients may have a visibly narrowed right ear canal, reduced airflow or drainage, and possible conductive hearing loss. Clinical features vary; refer to documentation.
When to use this code
Use H61.311 when the record documents acquired stenosis of the right external ear canal and links it to prior trauma. Code it when the provider specifies the right side and the post-traumatic cause. If the note does not clearly state trauma or laterality, check documentation.
Do not use for
Do not use this code for congenital canal narrowing or stenosis from infection, surgery, or other nontraumatic causes unless the documentation supports it. Do not assign it when the side is not right.
Coding tip
Verify both laterality and the traumatic cause in the provider note before coding H61.311.
