ICD-10 Code H62.8X3 – Other disorders of external ear in diseases classified elsewhere, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H62.8X3 – Other disorders of external ear in diseases classified elsewhere, bilateral
What it is
This code identifies bilateral external ear disorders that are caused by another underlying disease. Use it when the ear problem is documented as a manifestation of a separate condition, not as a primary ear diagnosis.
Clinical signs
Clinical features vary; refer to documentation. You may see external ear inflammation, irritation, swelling, pain, or other ear changes affecting both sides when a causative condition is recorded.
When to use this code
Use H62.8X3 when the provider links bilateral external ear disorder findings to another disease and specifies both ears. This is appropriate when the record clearly states the external ear condition is “in diseases classified elsewhere.” Check documentation for the underlying cause.
Do not use for
Do not use this code for a primary external ear disorder without an underlying disease, or when only one ear is involved. If bilateral involvement or the causal condition is not documented, check documentation.
Coding tip
Always code the underlying disease first when required, and use this code only when the record explicitly supports a bilateral manifestation.
