Congenital bowing of long bones of leg, unspecified

This diagnosis code signifies a birth defect characterized by an abnormal curvature or bending of the long bones in the lower extremities. It indicates that the specific leg bone affected by the bowing is not documented or is not yet determined.

Apply this code when medical records clearly state congenital bowing of the long bones of the leg, but do not specify which bone (e.g., tibia, fibula, femur) is involved. Documentation should confirm the congenital nature of the bowing and its location in the leg.

• Avoid using this code if the specific long bone affected by the bowing is clearly identified; instead, use a more specific code if available.
• Distinguish from acquired bowing deformities, which would be coded differently.
• Look for associated congenital anomalies that may require additional coding.
