ICD-10 Code H61.323 – Acquired stenosis of external ear canal secondary to inflammation and infection, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.323 – Acquired stenosis of external ear canal secondary to inflammation and infection, bilateral
What it is
This code identifies a narrowed external ear canal in both ears that developed after inflammation or infection. It reflects an acquired structural change, not a congenital condition.
Clinical signs
Common findings include reduced ear canal patency, difficulty examining the tympanic membrane, and symptoms such as hearing reduction or ear fullness. Clinical features vary; refer to documentation.
When to use this code
Use H61.323 when the record clearly states bilateral external ear canal stenosis caused by prior inflammation or infection. You should also use it when the provider documents post-inflammatory or post-infectious narrowing of both canals. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for congenital ear canal narrowing or for unilateral disease. Also avoid it when the chart only mentions otitis, swelling, or obstruction without documented stenosis.
Coding tip
Confirm both laterality and the acquired inflammatory or infectious cause before assigning H61.323.
