ICD-10 Code H61.302 – Acquired stenosis of left external ear canal, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.302 – Acquired stenosis of left external ear canal, unspecified
What it is
This code identifies an acquired narrowing of the left external ear canal. Use it when the record documents stenosis of the left ear canal without a more specific cause or detail.
Clinical signs
Findings may include reduced ear canal diameter, blocked cerumen drainage, hearing complaints, or difficulty visualizing the tympanic membrane. Clinical features vary; refer to documentation.
When to use this code
Use H61.302 when the provider documents acquired stenosis affecting only the left external ear canal. It is appropriate when the note does not identify a more specific subtype, cause, or associated condition. Confirm laterality and that the narrowing is acquired, not congenital.
Do not use for
Do not use this code for congenital ear canal narrowing or for right-sided or bilateral stenosis. If the chart describes another ear disorder as the primary diagnosis, check documentation.
Coding tip
Verify laterality carefully; “left” must be clearly documented to support H61.302.
