ICD-10 Code H61.391 – Other acquired stenosis of right external ear canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.391 – Other acquired stenosis of right external ear canal
What it is
This code identifies an acquired narrowing of the right external ear canal. It applies when the stenosis is not congenital and documentation specifies the right side.
Clinical signs
Patients may report reduced hearing, ear fullness, or recurrent blockage of the canal. Clinical features vary; refer to documentation for exam findings such as visible narrowing or obstruction.
When to use this code
Use this code when the record clearly states acquired stenosis of the right external ear canal. It is appropriate for documented narrowing from prior inflammation, trauma, surgery, or other acquired causes when the right ear is specified. Check documentation if the cause is unclear.
Do not use for
Do not use it for congenital ear canal narrowing or for left-sided or bilateral disease. Do not assign it when the note describes simple cerumen impaction or another condition without documented stenosis.
Coding tip
Confirm the laterality and that the narrowing is acquired before assigning H61.391.
