ICD-10 Code H95.812 – Postprocedural stenosis of left external ear canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.812 – Postprocedural stenosis of left external ear canal
What it is
This code identifies narrowing of the left external ear canal that develops after a procedure. It indicates an acquired postoperative complication affecting the ear canal’s patency.
Clinical signs
Patients may have reduced ear canal opening, difficulty with examination, or symptoms related to obstruction. Clinical features vary; refer to documentation.
When to use this code
Use H95.812 when the provider documents postprocedural stenosis specifically affecting the left external ear canal. Code it when the narrowing is described as a complication or sequela of an ear procedure, not as a congenital or inflammatory problem. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for right or bilateral ear canal stenosis, or for nonspecific external ear narrowing without postoperative documentation. Do not use it when the condition is due to infection, trauma, or another nonprocedural cause.
Coding tip
Verify both laterality and the procedural relationship in the operative or follow-up note before assigning H95.812.
