Webbed fingers, left hand

This code describes the congenital anomaly of syndactyly affecting the left hand, specifically where two or more fingers are fused together by a web of skin. This condition can range from a partial fusion involving only skin to a complete fusion involving bone, and it impacts the normal separation and function of the digits.

Use this code when documentation explicitly states "webbed fingers" or "syndactyly" of the left hand. This applies to congenital cases identified at birth or during early childhood examinations. Supporting documentation should include physical exam findings detailing the affected digits and laterality.

• Always confirm laterality (left, right, bilateral) from the physician's documentation.
• Distinguish between simple syndactyly (skin only) and complex syndactyly (involving bone, nerves, or blood vessels), though this specific code does not differentiate.
• Do not confuse with acquired adhesions or contractures, which are coded differently.
