Fused toes, left foot

This code describes a congenital anomaly where two or more toes on the left foot are abnormally joined together, either by soft tissue (syndactyly) or bone (synostosis). This fusion can range from partial to complete and may affect one or more digits.

Assign this code when documentation specifies fused toes exclusively on the left foot. This is typically identified during a physical examination, often in infancy or early childhood, and may be confirmed with imaging studies like X-rays.

• Differentiate between soft tissue fusion (syndactyly) and bony fusion (synostosis) if specified, though this code covers both.
• Ensure the laterality is clearly documented as "left foot" to avoid miscoding.
• Do not use this code for fused fingers or for fused toes affecting both feet or the right foot only.
