Longitudinal reduction defect of left radius

This code signifies a congenital anomaly characterized by the partial or complete absence of the radius bone in the left forearm, resulting in a shortened or absent forearm on that side. This malformation can range from mild hypoplasia to complete aplasia of the radius.

Use this code for patients diagnosed with a congenital deficiency of the left radius, often presenting with a club hand or radial club hand deformity. Documentation should clearly specify the affected side and confirm the diagnosis of a longitudinal reduction defect of the radius.

• Ensure the documentation specifies "left" to differentiate from the right or bilateral involvement.
• Do not confuse with transverse reduction defects or other congenital anomalies of the upper limb.
• Consider co-occurring congenital anomalies, such as those associated with VACTERL association, and code them separately.
