ICD-10 Code H60.399 – Other infective otitis externa, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.399 – Other infective otitis externa, unspecified ear
What it is
This code identifies an infective inflammation of the external ear canal when the ear is not specified. Use it for an infection of the outer ear, not the middle or inner ear.
Clinical signs
Typical findings include ear canal pain, tenderness, redness, swelling, and possible discharge. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents infective otitis externa but does not identify the right or left ear. It also fits cases where the provider describes an external ear infection and laterality is not stated. If the note names a different otitis externa type, code that more specific diagnosis instead.
Do not use for
Do not use this code for noninfective ear canal inflammation or for otitis media. If the documentation specifies a right or left ear, choose the laterality-specific code instead.
Coding tip
Check the note for laterality and infection type before assigning H60.399.
