Congenital pes cavus, left foot

This code identifies a congenital deformity of the left foot characterized by an abnormally high arch, also known as pes cavus. This structural anomaly is present at birth and results in an excessive plantar flexion of the forefoot relative to the hindfoot.

Apply this code when documentation clearly indicates a diagnosis of congenital pes cavus affecting the left foot. This diagnosis is typically made by a physician based on physical examination findings and may be supported by imaging studies.

• Ensure the documentation specifies "congenital" to differentiate from acquired pes cavus.
• Verify the laterality is explicitly stated as "left foot" to avoid incorrect coding.
• Distinguish from other foot deformities like talipes equinovarus (clubfoot) or pes planus (flatfoot).
