ICD-10 Code H60.311 – Diffuse Otitis Externa, Right Ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.311 – Diffuse otitis externa, right ear
What it is
This code identifies diffuse inflammation and infection of the external ear canal on the right side. It is used when the condition affects the canal broadly, not just one focal spot.
Clinical signs
Typical findings include ear canal redness, swelling, pain, and tenderness, often worsened by moving the outer ear. Clinical features vary; refer to documentation.
When to use this code
Use H60.311 when the provider documents diffuse otitis externa in the right ear. Apply it when the record clearly states right-sided involvement and does not describe a different ear condition. Check documentation if laterality or extent is unclear.
Do not use for
Do not use this code for otitis externa of the left ear, bilateral disease, or a localized canal lesion. Do not assign it when the note only says “ear pain” without otitis externa documentation.
Coding tip
Always confirm both the diffuse nature and right-ear laterality in the provider’s note before coding.
