Fused fingers, left hand

This code describes syndactyly, a congenital anomaly where two or more fingers on the left hand are abnormally joined or fused together. This fusion can involve skin, soft tissue, or bone, resulting in a webbed or conjoined appearance of the digits.

Assign this code for patients diagnosed with congenital fusion of fingers specifically affecting the left hand. Documentation should clearly specify the laterality and the nature of the digital fusion. This code is appropriate for initial diagnosis and subsequent encounters related to the condition, including surgical correction.

• Ensure documentation specifies "left hand" to support this laterality-specific code.
• Distinguish from polydactyly (extra digits) or other congenital malformations of the hand.
• Consider additional codes for any associated anomalies or complications, such as bone involvement or functional impairment.
