Disp fx of left tibial spine, subs for clos fx w nonunion

This code signifies a fracture of the tibial spine (a bony prominence on the top of the tibia within the knee joint) on the left leg, where the bone fragments are no longer in their normal alignment. The fracture has not healed as expected, indicating a nonunion, and the patient is presenting for follow-up care or treatment of this ongoing issue.

Apply this code when documenting a patient's visit for continued management of a previously diagnosed, displaced left tibial spine fracture that has failed to unite. This includes scenarios where the patient is undergoing further evaluation, non-surgical treatment adjustments, or preparing for surgical intervention due to the nonunion.

• Ensure documentation clearly specifies "left" side and "displaced" nature of the fracture.
• Confirm the encounter is for a "subsequent" visit and the fracture is "closed" (skin intact).
• Verify the physician's assessment explicitly states "nonunion" to justify this specific seventh character.
