Accessory toe(s)

This diagnosis code signifies the presence of one or more supernumerary toes, which are extra digits on the foot. These accessory toes can vary in size and structure, ranging from small skin tags to fully formed digits with bone. This condition is a congenital anomaly of the lower limb.

Apply this code when documentation clearly indicates the presence of an extra digit on the foot. This typically includes findings from physical examination, imaging studies (e.g., X-rays confirming bone structure), or surgical reports detailing the excision of such a digit. It is appropriate for both symptomatic and asymptomatic accessory toes.

• Do not confuse with syndactyly (fused digits) or polydactyly of the hand, which have distinct codes.
• Specify laterality (left, right, or bilateral) if documented, using the appropriate seventh character.
• Consider additional codes for any associated congenital anomalies or complications, such as pain or functional impairment.
