ICD-10 Code H60.521 – Acute chemical otitis externa, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.521 – Acute chemical otitis externa, right ear
What it is
H60.521 identifies an acute inflammation of the right external ear canal caused by chemical irritation or exposure. Use it when the condition is specifically documented as chemical and limited to the right ear.
Clinical signs
Typical findings include ear canal redness, swelling, pain, itching, or tenderness after exposure to an irritant. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states acute chemical otitis externa affecting the right ear. It is appropriate when the provider links the ear canal inflammation to a chemical exposure, such as a cleaning agent or other irritant. Laterality must be documented as right.
Do not use for
Do not use it for nonspecific otitis externa, fungal infection, or ear pain without documented chemical cause. If the side is not right, or the cause is unclear, check documentation.
Coding tip
Verify both the chemical cause and right-ear laterality before assigning H60.521.
