ICD-10 Code H61.319 – Acquired stenosis of external ear canal secondary to trauma, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.319 – Acquired stenosis of external ear canal secondary to trauma, unspecified ear
What it is
H61.319 identifies narrowing of the external ear canal that developed after trauma. Use it when the stenosis is acquired, trauma-related, and the affected ear is not specified in the record.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include a narrowed ear canal on exam and related conductive hearing complaints, but the chart should support the post-traumatic cause.
When to use this code
Use this code when the provider documents acquired external ear canal stenosis due to prior injury and does not identify the right or left ear. It also fits follow-up visits where the condition remains active and is being evaluated or monitored. Check documentation if trauma history or laterality is unclear.
Do not use for
Do not use it for congenital canal narrowing or stenosis from infection, surgery, or other non-traumatic causes. If the ear side is documented, choose the laterality-specific code instead.
Coding tip
Confirm both the traumatic cause and the unspecified ear before assigning H61.319.
