Congenital vertical talus deformity, right foot

This code represents a congenital foot deformity where the talus bone is vertically oriented, leading to a rigid flatfoot appearance. The condition is present at birth and affects the right foot, characterized by a prominent talar head on the plantar aspect and a dorsiflexed forefoot. This structural anomaly prevents normal ankle and foot motion.

Use this code for patients diagnosed with a congenital vertical talus deformity specifically affecting the right foot. Documentation should clearly state the congenital nature of the deformity and its unilateral presentation on the right side. This code is appropriate for initial encounters, follow-up care, and surgical interventions related to this specific condition.

• Ensure documentation specifies "congenital" and "right foot" to support this code.
• Distinguish from acquired flatfoot deformities or other congenital foot anomalies like clubfoot (talipes equinovarus).
• Consider laterality; a separate code exists for the left foot (Q66.82) and bilateral involvement (Q66.89).
