Other noninfective acute otitis externa, unspecified ear

This code signifies an acute inflammation of the external ear canal that is not caused by an infection. It typically involves irritation, swelling, and discomfort of the outer ear, without a specified laterality. This condition is often triggered by chemical irritants, allergic reactions, or excessive moisture, rather than bacterial or fungal pathogens.

Apply this code when documentation clearly indicates acute otitis externa due to non-infectious causes, and the specific ear affected is not documented. This is appropriate for cases like contact dermatitis of the ear canal, allergic reactions to ear products, or irritation from foreign bodies (after removal), where an infectious etiology has been ruled out or is not suspected.

• Only use this code when the documentation explicitly states "noninfective" and the laterality is "unspecified."
• Avoid using this code if an infectious agent (bacterial, fungal) is identified or suspected; instead, refer to codes within H60.3-H60.4.
• If the specific ear (right, left, bilateral) is documented, use the more specific codes H60.591, H60.592, or H60.593.
