ICD-10 Code H62.8 – Other disorders of external ear in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H62.8 – Other disorders of external ear in diseases classified elsewhere
What it is
This code identifies external ear disorders caused by another underlying disease. Use it when the ear finding is secondary to a documented condition rather than a primary ear disease.
Clinical signs
Clinical features vary; refer to documentation. You may see external ear pain, swelling, irritation, or visible changes linked to the underlying disease process.
When to use this code
Use H62.8 when the record clearly states an external ear disorder is due to another classified disease. It fits secondary ear involvement, such as when the provider links the ear problem to a systemic or adjacent condition. Check documentation for the causative diagnosis and any additional code requirements.
Do not use for
Do not use this code for primary ear conditions with no stated underlying cause. If the documentation does not link the disorder to another disease, check documentation for a more specific external ear code.
Coding tip
Always code the underlying disease first when it is documented as the cause.
