Congen absence of thigh and lower leg w foot present, bi

This code describes a rare congenital malformation characterized by the complete absence of both the thigh and lower leg bones (femur, tibia, and fibula) on both sides of the body, while the foot or feet are still present. This condition results in severely shortened or absent lower limbs, with the feet often attached directly to the pelvis or trunk.

Use this code for patients diagnosed with bilateral congenital phocomelia affecting the entire thigh and lower leg segments, but with preserved foot structures. Documentation should clearly state the bilateral nature of the defect and specify the absence of the proximal and distal long bones of the leg, confirming the presence of the foot.

• Ensure documentation explicitly states "bilateral" involvement; otherwise, a unilateral code may be more appropriate.
• Differentiate from other congenital limb deficiencies where only parts of the thigh or lower leg are absent, or where the foot is also absent.
• Consider sequencing this code as the primary diagnosis when it is the main reason for the encounter, especially for surgical correction or prosthetic fitting.
