Longitudinal reduction defect of unspecified femur

This code signifies a congenital anomaly characterized by the partial or complete absence of the femur along its longitudinal axis, without further specification of the affected side. It represents a birth defect where the thigh bone has failed to develop normally in length.

Use this code for cases of congenital femoral deficiency when the specific side (left or right) is not documented. This diagnosis is typically made at birth or during prenatal imaging. Documentation should clearly state a "longitudinal reduction defect of the femur" without laterality.

• Do not use this code if the laterality (left or right femur) is specified; instead, use the more specific codes Q72.41 (right) or Q72.42 (left).
• This code is for congenital conditions only; do not use for acquired femoral defects or injuries.
• Always review the medical record for any additional congenital anomalies that may need to be coded separately.
