Congenital complete absence of left upper limb

This code signifies the complete congenital absence of the entire left upper extremity, meaning the limb failed to develop at all during gestation. This is a severe form of limb reduction defect affecting the left side.

Apply this code when documentation clearly states the congenital and complete absence of the left upper limb. This is typically identified at birth or prenatally and confirmed by physical examination and imaging studies.

• Ensure documentation specifies "complete absence" and not a partial deficiency or amputation.
• Verify the laterality is explicitly stated as "left."
• Do not confuse with acquired amputations or other types of congenital limb malformations.
