ICD-10 Code H60.529 – Acute chemical otitis externa, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.529 – Acute chemical otitis externa, unspecified ear
What it is
This code identifies an acute inflammation of the external ear canal caused by chemical irritation or exposure, with no ear laterality specified. Use it when documentation clearly supports a chemical cause rather than infection or trauma.
Clinical signs
Typical findings include ear canal redness, swelling, pain, itching, or a burning sensation after chemical exposure. Clinical features vary; refer to documentation.
When to use this code
Use H60.529 when the record states acute chemical otitis externa and the affected ear is not documented as right or left. It also fits when the clinician links the canal inflammation to a chemical irritant, such as cleaning agents or other corrosive exposure. Check documentation if the cause is unclear.
Do not use for
Do not use this code for infectious otitis externa, chronic ear canal disease, or simple ear pain without documented chemical irritation. If the note does not confirm a chemical cause, check documentation.
Coding tip
Confirm both the acute chemical cause and the unspecified ear laterality before assigning H60.529.
