ICD-10 Code H60.523 – Acute chemical otitis externa, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.523 – Acute chemical otitis externa, bilateral
What it is
Use this code for a sudden inflammatory condition of both external ear canals caused by chemical exposure. It indicates irritation or injury from a chemical agent, not infection alone.
Clinical signs
Typical findings include ear canal redness, swelling, pain, itching, or drainage after exposure to a chemical irritant. Clinical features vary; refer to documentation.
When to use this code
Use H60.523 when the record clearly documents acute chemical otitis externa affecting both ears. The note should link the condition to a chemical cause, such as a cleansing product, solvent, or other irritant. If laterality or cause is unclear, check documentation.
Do not use for
Do not use this code for infectious otitis externa, chronic ear canal disease, or nonspecific ear pain without chemical exposure. Do not assume bilateral involvement unless the documentation states both ears.
Coding tip
Verify both the chemical cause and bilateral laterality in the chart before assigning H60.523.
