Cellulitis of right external ear

This code signifies an acute bacterial infection of the skin and subcutaneous tissue of the right outer ear. It typically presents with localized redness, swelling, warmth, and tenderness, often without a well-defined border. The infection can arise from minor trauma, insect bites, or spread from adjacent infections.

Apply this code when documentation clearly indicates cellulitis affecting the patient's right external ear. Supporting documentation should include a physician's diagnosis of cellulitis and laterality (right ear). This code is appropriate for both initial and subsequent encounters for this specific condition.

• Ensure documentation specifies "right" external ear; otherwise, an unspecified laterality code may be necessary.
• Distinguish from perichondritis (H60.0-) which involves the cartilage, though cellulitis can sometimes precede or coexist with it.
• Look for associated conditions like otitis externa (H60.3-) if the infection extends into the ear canal.
