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

This code signifies a birth defect characterized by the complete congenital absence of both the lower leg (tibia and fibula) and the foot in an unspecified lower extremity. This malformation results in a significant limb deficiency affecting the entire distal portion of the leg.

Apply this code when documentation clearly indicates a congenital agenesis or aplasia of both the lower leg and the foot. This is typically diagnosed at birth or prenatally via imaging, and confirmed by physical examination. Use this code when the specific side (left or right) of the affected limb is not documented.

• Ensure documentation specifies "congenital absence" of both the lower leg and foot, not just one or the other.
• Do not use this code if the laterality (left or right) of the affected limb is known; instead, use the more specific codes (Q72.21 or Q72.22).
• Consider additional codes for any associated congenital anomalies or syndromes, if documented.
