Congenital pes planus, right foot

This code signifies a congenital flatfoot deformity affecting the right foot. In this condition, the arch of the foot is absent or significantly reduced from birth, leading to the entire sole of the foot making contact with the ground when standing. It is a structural abnormality present at birth rather than an acquired condition.

Use this code when documentation explicitly states a diagnosis of congenital pes planus specifically affecting the patient's right foot. Supporting documentation would include physician notes detailing the congenital nature of the flatfoot and specifying the right side. This code is appropriate for initial evaluations, follow-up appointments, and surgical interventions related to this specific condition.

• Ensure the documentation clearly specifies "congenital" and "right foot" to differentiate from acquired flatfoot or bilateral/left-sided involvement.
• Do not use this code for flexible or acquired pes planus; those conditions have different ICD-10-CM codes.
• If both feet are affected, a separate code for the left foot (Q66.52) or a bilateral code (Q66.53) would be more appropriate, depending on the specific documentation.
