ICD-10 Code H61.393 – Other acquired stenosis of external ear canal, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.393 – Other acquired stenosis of external ear canal, bilateral
What it is
H61.393 identifies acquired narrowing of both external ear canals. Use it when the stenosis is not congenital and affects each ear canal, making the passage smaller than normal.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe narrowed ear canals on examination, with possible hearing difficulty, trapped debris, or recurrent blockage.
When to use this code
Use this code when the provider documents bilateral acquired stenosis of the external ear canal. It is appropriate when the narrowing is described as other acquired stenosis and not linked to a congenital condition. Confirm laterality and acquired status in the note.
Do not use for
Do not use it for congenital ear canal narrowing or for unilateral stenosis. If the chart only mentions earwax, infection, or another cause without documented stenosis, check documentation.
Coding tip
Verify both laterality and that the stenosis is acquired before assigning H61.393.
