ICD-10 Code H61.301 – Acquired stenosis of right external ear canal, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.301 – Acquired stenosis of right external ear canal, unspecified
What it is
This code identifies an acquired narrowing of the right external ear canal. Use it when documentation shows stenosis or stricture of the right ear canal without a more specific cause.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a narrowed canal on exam, reduced visibility of the tympanic membrane, or conductive hearing complaints if noted by the clinician.
When to use this code
Use H61.301 when the record clearly states acquired stenosis of the right external ear canal and no laterality-specific alternative code is documented. It may also apply when the provider documents “right ear canal stenosis” or similar wording. Check documentation if the cause is congenital or if the site is not clearly the right ear.
Do not use for
Do not use this code for congenital ear canal narrowing, bilateral disease, or unspecified ear canal stenosis when laterality is not documented. Check documentation if the finding is due to another ear disorder.
Coding tip
Confirm laterality and that the stenosis is acquired, because those details determine whether H61.301 is the correct code.
