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

This code signifies a displaced fracture of the tibial spine in the left knee that has not healed correctly, resulting in malunion. It specifically indicates that the patient is in a subsequent phase of care for this closed fracture, meaning the initial treatment has occurred and the focus is now on managing the malunion.

Apply this code when documenting follow-up care for a patient with a previously treated, closed, displaced fracture of the left tibial spine that has healed in an anatomically incorrect position. This would be appropriate for office visits, imaging studies, or surgical planning related to correcting the malunion.

• Ensure the documentation clearly specifies "left" tibial spine and "displaced" fracture.
• Verify that the encounter is for "subsequent" care and that "malunion" is explicitly noted as the complication.
• Do not use this code for initial treatment of the fracture or for nonunion; a different code would be appropriate for those scenarios.
