Accessory auricle

This code represents a congenital anomaly characterized by the presence of a small, benign nodule or skin tag, typically located anterior to the tragus of the ear. These accessory auricles, also known as preauricular tags or ear tags, are composed of skin and sometimes cartilage, and are generally asymptomatic. They are a developmental defect of the first and second branchial arches.

Use this code when documentation clearly indicates the presence of an accessory auricle or preauricular tag. This code is appropriate for initial diagnosis, evaluation, or surgical excision of such a lesion. Supporting documentation should specify the location and nature of the accessory tissue.

• Do not confuse with other ear malformations like microtia or anotia; this code is specific to accessory tissue.
• If surgical excision is performed, ensure the operative report clearly documents the removal of an accessory auricle.
• Consider sequencing this code as a primary diagnosis if the accessory auricle is the sole reason for the encounter, or as a secondary diagnosis if it's an incidental finding during an encounter for another condition.
