Fused toes, unspecified foot

This code describes the congenital condition where two or more toes are abnormally joined together, either by soft tissue (syndactyly) or bone (synostosis), without specifying which foot is affected. It represents a structural anomaly of the foot present at birth.

Use this code when documentation indicates fused toes are present but does not specify laterality (left or right foot). This code is appropriate for initial evaluations or follow-up appointments where the laterality of the fused toes has not yet been determined or recorded.

• Avoid using this code if the medical record clearly specifies which foot (left or right) is affected; instead, use the more specific codes for fused toes of the right (Q70.21) or left (Q70.22) foot.
• Ensure the documentation confirms a congenital fusion of toes, not an acquired condition or trauma.
• This code is for syndactyly or synostosis of toes; do not confuse with fused fingers (Q70.0-Q70.1).
