Congen absence of both lower leg and foot, right lower limb

This code describes a severe congenital malformation characterized by the complete absence of the tibia, fibula, and foot structures in the right lower limb at birth. This condition is a form of phocomelia or amelia, specifically affecting the lower leg and foot.

Use this code when documentation clearly indicates a congenital absence of both the lower leg (tibia and fibula) and the entire foot on the patient's right side. This diagnosis is typically made at birth or prenatally via imaging studies.

• Ensure laterality is explicitly documented as "right" to support this specific code.
• Distinguish from other congenital limb deficiencies where only parts of the lower leg or foot are absent.
• Do not confuse with acquired amputations or other forms of limb reduction defects.
