Longitudinal reduction defect of right femur

This code describes a congenital malformation characterized by the partial or complete absence of the right femur along its longitudinal axis. This defect results in a shortened or absent right thigh bone, often accompanied by other limb anomalies. It is a birth defect affecting the development of the lower extremity.

Use this code for patients diagnosed with a congenital longitudinal deficiency specifically affecting the right femur. Documentation should clearly state "longitudinal reduction defect of right femur," "femoral hypoplasia," or "femoral agenesis" on the right side. This code is appropriate for initial diagnosis and subsequent encounters related to the management of this congenital anomaly.

• Ensure laterality is explicitly documented as "right" to support this specific code.
• Distinguish from transverse reduction defects, which involve a complete absence of the distal portion of the limb.
• Code any associated congenital anomalies of the lower limb or other body systems separately.
