Congenital bowing of femur

This code describes a birth defect characterized by an abnormal curvature or bending of the thigh bone (femur) present at birth. This bowing can affect various parts of the femur and may be associated with other skeletal anomalies.

Assign this code when medical record documentation clearly indicates a diagnosis of congenital bowing of the femur. This diagnosis is typically made through physical examination and imaging studies, such as X-rays, performed shortly after birth or during infancy.

• Differentiate from acquired bowing deformities, which would be coded differently.
• Ensure documentation specifies "congenital" to support the use of this code.
• Review for any associated congenital anomalies of the hip or other bones, as these may require additional codes.
