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

This code signifies a fracture of the tibial spine in the left knee that is not displaced, meaning the bone fragments are still in their anatomical position. The patient is in a subsequent phase of treatment, and the fracture has healed improperly, resulting in a malunion. This indicates a complication where the bone has united in a deformed or misaligned position.

This code is appropriate when a patient presents for follow-up care of a previously diagnosed nondisplaced left tibial spine fracture that has healed with a noticeable deformity or angulation. It would be used for encounters where the malunion is being assessed, monitored, or treated, such as for physical therapy, imaging to evaluate the malunion, or discussion of surgical correction.

• Ensure documentation clearly states "malunion" and specifies the left tibial spine.
• Verify the fracture was initially nondisplaced.
• This code is for subsequent encounters, not the initial treatment of the fracture.
