ICD-10 Code H60.509 – Unspecified acute noninfective otitis externa, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.509 – Unspecified acute noninfective otitis externa, unspecified ear
What it is
This code identifies an acute inflammation of the external ear canal that is not caused by infection, with the ear side not specified in the record. Use it when documentation confirms noninfective otitis externa but does not name a more specific cause.
Clinical signs
Typical findings may include ear canal pain, itching, redness, swelling, or tenderness, especially with manipulation of the outer ear. Clinical features vary; refer to documentation.
When to use this code
Use H60.509 when the provider documents acute noninfective otitis externa and does not specify left or right ear. It also fits cases where the cause is noninfectious, such as irritation or dermatitis, but the chart lacks a more exact diagnosis. Check documentation if the condition is chronic or infectious.
Do not use for
Do not use this code for infectious otitis externa or for chronic external ear canal inflammation. If the record specifies a different ear or a more specific noninfective cause, code that instead.
Coding tip
Confirm both acuity and noninfective status in the note before assigning H60.509.
