ICD-10 Code H60.502 – Unspecified acute noninfective otitis externa, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.502 – Unspecified acute noninfective otitis externa, left ear
What it is
Use this code for an acute, noninfective inflammation of the external ear canal in the left ear when the cause is not specified. It identifies the location and laterality, but not a defined etiology.
Clinical signs
Typical findings include ear pain, tenderness of the outer ear canal, itching, redness, and swelling. Clinical features vary; refer to documentation if the record does not clearly describe a noninfective process.
When to use this code
Assign this code when the provider documents acute otitis externa of the left ear and states it is noninfective or gives no infectious cause. Use it when the note supports left-sided disease but does not identify a more specific noninfective subtype. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use this code for infectious otitis externa, chronic disease, or right/unspecified ear cases. If the chart identifies a more specific cause or site, code that instead.
Coding tip
Always verify both acuity and laterality in the provider note before assigning H60.502.
