Split foot, unspecified lower limb

This code describes a congenital anomaly characterized by a deep cleft extending longitudinally through the central rays of the foot, resulting in a V-shaped or U-shaped defect. It involves the absence or hypoplasia of central metatarsals and phalanges, often leading to a two-part foot. This specific code indicates that the affected lower limb (left or right) is not specified.

Use this code when documentation clearly states a diagnosis of "split foot" or "cleft foot" without specifying laterality. This diagnosis is typically made at birth or early childhood based on physical examination and imaging studies. Supporting documentation should include physician notes detailing the malformation.

• Do not use this code if the laterality (left or right foot) is documented; instead, use the more specific codes Q72.71 (split foot, right lower limb) or Q72.72 (split foot, left lower limb).
• Ensure the documentation confirms the congenital nature of the condition, as acquired deformities would be coded differently.
• Consider any associated congenital anomalies that may also need to be coded, as split foot can occur as part of a syndrome.
