ICD-10 Code H60.503 – Unspecified acute noninfective otitis externa, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.503 – Unspecified acute noninfective otitis externa, bilateral
What it is
This code identifies an acute inflammation of both external ear canals that is not caused by infection and is not further specified. Use it when the record documents bilateral otitis externa but does not name the cause.
Clinical signs
Typical findings include ear canal pain, tenderness, redness, and swelling, sometimes with itching or discomfort when the outer ear is moved. Clinical features vary; refer to documentation.
When to use this code
Use H60.503 when the clinician documents acute noninfective otitis externa affecting both ears and does not identify a more specific subtype. It also fits when laterality is clear, but the cause remains unspecified. Check documentation if there is any mention of infection, trauma, eczema, or another defined condition.
Do not use for
Do not use this code for infectious otitis externa, chronic ear canal disease, or unilateral disease. If the chart identifies a specific noninfective cause, code that condition instead.
Coding tip
Confirm both laterality and noninfective status in the note before assigning H60.503.
