Cellulitis of external ear, unspecified ear

This code signifies an acute, spreading bacterial infection of the dermis and subcutaneous tissue of the external ear. It presents with erythema, warmth, swelling, and tenderness without a clearly defined border. The infection is localized to the outer ear structures.

Apply this code when documentation confirms cellulitis affecting the auricle or external auditory canal, and the specific ear (left or right) is not specified. It is appropriate for initial encounters and subsequent care when the ear laterality remains undetermined. Supporting documentation includes physician notes detailing the signs and symptoms of cellulitis of the external ear.

• Do not use this code if the laterality (left or right ear) is documented; instead, choose the more specific H60.11 or H60.12.
• Distinguish from perichondritis (H60.0-) which involves the cartilage, though cellulitis can sometimes precede or accompany it.
• Ensure documentation clearly indicates "unspecified ear" if laterality is truly unknown, rather than assuming.
