Other congenital varus deformities of feet, left foot

This code signifies a congenital inward angulation or deviation of the left foot, excluding clubfoot (talipes equinovarus). It encompasses various non-clubfoot varus deformities present at birth, such as metatarsus adductus or other structural abnormalities causing the foot to turn inward.

Apply this code when documentation specifies a congenital varus deformity affecting the left foot, and the condition is not explicitly diagnosed as talipes equinovarus. Supporting documentation should clearly indicate the laterality and the specific type of varus deformity, if known, or simply "other congenital varus deformity."

• Differentiate carefully between this code and Q66.02 (congenital talipes equinovarus, left foot).
• Ensure laterality (left foot) is explicitly documented; otherwise, an unspecified laterality code may be more appropriate.
• Review documentation for any associated congenital anomalies that may require additional coding.
