ICD-10 Code H61.3 – Acquired stenosis of external ear canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.3 – Acquired stenosis of external ear canal
What it is
H61.3 identifies narrowing of the external ear canal that develops after birth. Use it when documentation shows an acquired, not congenital, stenosis affecting one or both ear canals.
Clinical signs
Findings may include a visibly narrowed canal, reduced ability to examine the tympanic membrane, and conductive hearing complaints. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acquired stenosis, stricture, or narrowing of the external auditory canal. It may also fit follow-up visits for a known acquired canal narrowing when the diagnosis remains active. Check documentation if the cause is not stated.
Do not use for
Do not use H61.3 for congenital ear canal narrowing or for simple cerumen impaction. If the record only describes pain, infection, or swelling without stenosis, choose the documented condition instead.
Coding tip
Verify that the record says “acquired” and that the canal narrowing is the diagnosis, not just an exam limitation.
