ICD-10 Code H61.899 – Other specified disorders of external ear, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.899 – Other specified disorders of external ear, unspecified ear
What it is
This code identifies a documented disorder of the external ear that does not fit a more specific ICD-10-CM category. The record does not specify the affected ear, so you should code it as unspecified ear.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible external ear abnormalities, discomfort, swelling, or irritation, but the exact diagnosis should be stated in the chart.
When to use this code
Use H61.899 when the provider documents an external ear disorder and no more specific code applies. It is appropriate when the note identifies the condition but does not name the right or left ear. Check documentation if the record is vague or laterality is available.
Do not use for
Do not use this code when a more specific external ear diagnosis is documented, or when the condition involves the middle or inner ear. If the ear side is known, choose the laterality-specific code instead.
Coding tip
Look for laterality and a more precise diagnosis first; default to H61.899 only when the external ear disorder is otherwise unspecified.
