ICD-10 Code H95.813 – Postprocedural stenosis of external ear canal, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.813 – Postprocedural stenosis of external ear canal, bilateral
What it is
This code identifies narrowing of both external ear canals that occurs after a procedure or surgery. Use it when documentation clearly states the stenosis is postoperative and bilateral.
Clinical signs
Clinical features may include reduced ear canal patency, difficulty visualizing the tympanic membrane, or symptoms of blockage. Clinical features vary; refer to documentation.
When to use this code
Use H95.813 when the provider documents bilateral external auditory canal stenosis as a direct result of prior surgery or another procedure. It fits postoperative scarring or narrowing affecting both sides. If the record does not clearly link the stenosis to a procedure, check documentation.
Do not use for
Do not use this code for congenital ear canal narrowing, infection-related swelling, or unilateral stenosis. If the cause is not postoperative, choose the more accurate diagnosis.
Coding tip
Verify both laterality and the postoperative cause in the operative or follow-up note before assigning H95.813.
