Acute chemical otitis externa, right ear

This code signifies an acute inflammatory condition of the external ear canal on the right side, specifically caused by exposure to a chemical irritant. This irritation leads to symptoms such as pain, redness, swelling, and discharge in the affected ear.

Assign this code when documentation clearly indicates an acute otitis externa in the right ear resulting from chemical exposure (e.g., harsh ear drops, cleaning solutions, or occupational chemical contact). Supporting documentation should specify the laterality and the chemical etiology.

• Ensure the documentation explicitly states "chemical" as the cause of the otitis externa, not bacterial or fungal.
• Verify laterality; this code is specific to the right ear. Use H60.522 for the left ear and H60.523 for bilateral involvement.
• Distinguish from allergic contact otitis externa (H60.53-) which implies an immune response rather than direct irritation.
