Acute perichondritis of left external ear

This code signifies an acute inflammatory condition affecting the perichondrium, the connective tissue covering the cartilage of the outer ear, specifically on the left side. It typically presents with pain, redness, and swelling of the left auricle.

Apply this code when documentation clearly indicates an acute inflammation of the perichondrium of the left external ear. This often arises from trauma, infection, or piercing complications. Ensure the medical record specifies the acute nature and laterality.

• Differentiate from chondritis (inflammation of the cartilage itself) or cellulitis (skin infection) of the ear, which have distinct codes.
• Confirm the laterality (left ear) is explicitly documented; codes exist for right and unspecified ears.
• Look for associated infectious agents if documented, as an additional code for the infection may be warranted.
