Nondisp fx of unsp tibial spine, subs for clos fx w nonunion

This code signifies a fracture of the tibial spine (a bony protrusion on the tibia within the knee joint) that has not shifted from its normal anatomical position. The patient is in a later stage of care for this injury, and the fracture has failed to heal properly, despite the skin remaining intact over the fracture site.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced tibial spine fracture is being treated for nonunion, and the fracture is still considered closed. This would typically involve ongoing management, such as repeat imaging, casting changes, or discussions regarding surgical intervention for the nonunion.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for a closed fracture of the tibial spine.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture site is unspecified within the tibial spine, as more specific codes exist if the medial or lateral spine is documented.
