Webbed fingers, bilateral

This code signifies the congenital malformation where the skin or other soft tissues connect two or more fingers, preventing their normal separation, affecting both hands. This condition, also known as syndactyly, can range from a partial webbing to a complete fusion of digits.

Apply this code when documentation clearly indicates congenital syndactyly affecting the fingers of both the left and right hands. This diagnosis is typically made at birth or early childhood and is supported by physical examination findings.

• Ensure documentation specifies "bilateral" involvement; otherwise, a unilateral code may be more appropriate.
• Distinguish between simple (skin only) and complex (involving bone, nail, or other tissues) syndactyly if further specificity is available, though this code does not differentiate.
• Do not confuse with other congenital hand malformations like polydactyly (extra digits) or brachydactyly (short digits).
