Cauliflower ear, left ear

This code describes the acquired deformity of the left auricle characterized by thickening and nodularity, often resulting from repeated trauma or inflammation. It represents the chronic, irreversible changes to the ear cartilage and overlying skin, giving it a lumpy or cauliflower-like appearance.

Use this code when documentation explicitly states "cauliflower ear" affecting the left ear. This condition is frequently seen in athletes involved in contact sports, such as wrestling or boxing, due to recurrent hematoma formation and subsequent fibrosis. Supporting documentation should clearly specify the laterality.

• Ensure documentation specifies "left ear" to avoid laterality errors.
• Do not confuse with congenital ear deformities; this code is for an acquired condition.
• Consider sequencing with an external cause code if the trauma leading to the condition is still relevant and being treated.
