ICD-10 Code H62.8X2 – Other disorders of left external ear in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H62.8X2 – Other disorders of left external ear in diseases classified elsewhere
What it is
This code identifies a disorder of the left external ear that is caused by another underlying disease. Use it when the ear finding is documented as secondary to a separate condition, not as a primary ear disease.
Clinical signs
Clinical features vary; refer to documentation. You may see external ear inflammation, irritation, swelling, pain, or other abnormal findings limited to the left ear, with an associated underlying diagnosis recorded elsewhere.
When to use this code
Use H62.8X2 when the provider documents a left external ear disorder as due to another disease, such as a systemic or adjacent condition. The record should clearly link the ear problem to that underlying cause. If the cause is not stated, check documentation before coding.
Do not use for
Do not use this code for primary disorders of the external ear without an underlying disease. Do not use it when the documentation does not specify the left side or does not support a secondary cause.
Coding tip
Always code the underlying condition first when it is documented as the cause of the left external ear disorder.
