ICD-10 Code H60.533 – Acute contact otitis externa, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.533 – Acute contact otitis externa, bilateral
What it is
This code identifies an acute inflammation of the external ear canal in both ears caused by contact irritation or allergy. Use it when the condition is documented as bilateral and contact-related.
Clinical signs
Typical findings include ear canal redness, swelling, itching, pain, or tenderness. Clinical features vary; refer to documentation for bilateral involvement and the contact trigger.
When to use this code
Use H60.533 when the provider documents acute contact otitis externa affecting both ears, such as dermatitis or irritation from an external exposure. You should also use it when the note clearly states bilateral disease and does not describe another primary ear disorder.
Do not use for
Do not use this code for chronic otitis externa, infectious swimmer’s ear, or unilateral disease. Check documentation if the record does not clearly support a contact cause.
Coding tip
Confirm both the acute contact cause and bilateral laterality in the assessment before assigning H60.533.
