Congenital pes planus, unspecified foot

This code identifies a congenital deformity characterized by the absence or collapse of the medial longitudinal arch of the foot, present from birth. It specifically refers to a flatfoot condition where the affected foot is not specified.

Assign this code when documentation indicates a diagnosis of congenital flatfoot without specifying laterality (e.g., "congenital pes planus"). This diagnosis is typically made in pediatric patients based on clinical examination and may be supported by imaging studies.

• Do not use this code if the documentation specifies laterality (left or right foot); instead, use the more specific codes.
• Distinguish from acquired pes planus (M21.4-), which develops later in life.
• Ensure the documentation clearly states "congenital" to support the use of this Q-code.
