Congenital absence of both lower leg and foot, bilateral

This code signifies a birth defect characterized by the complete absence of both the lower leg (tibia and fibula) and the foot on both sides of the body. This severe congenital anomaly results in significant functional impairment and requires extensive prosthetic and rehabilitative interventions.

Assign this code when medical documentation clearly states the congenital bilateral absence of the lower leg and foot. This diagnosis is typically made at birth or during prenatal imaging. Supporting documentation includes genetic reports, physical examination findings, and imaging studies confirming the bilateral agenesis.

• Ensure documentation explicitly states "bilateral" involvement; otherwise, a unilateral code may be more appropriate.
• Distinguish this from other congenital malformations of the lower limb, such as phocomelia or other reduction defects, where some portion of the limb may be present.
• Look for associated congenital anomalies, as these often occur together, and code them separately if documented.
