Disp fx of unsp tibial spin, 7thM

This code signifies a fracture of the tibial spine (a bony prominence on the tibia within the knee joint) that is no longer in its anatomical alignment. This specific instance involves an open fracture, meaning the skin was broken at the time of injury, classified as Type I or II, and the bone has failed to heal properly after initial treatment.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed displaced open tibial spine fracture (Type I or II) that has developed nonunion. This would include situations where surgical intervention for nonunion is being planned or performed, or during ongoing conservative management for the unhealed fracture.

• Ensure documentation clearly specifies "displaced" and "open fracture type I or II" for the initial injury.
• Confirm that "nonunion" is explicitly documented as the reason for the subsequent encounter.
• Do not use for initial fracture treatment or for closed fractures.
