Disp fx of l tibial spin, 7thN

This code describes a nonunion of a displaced fracture of the left tibial spine, which is a break in the bony prominence on the top of the tibia within the knee joint. The fracture was initially an open fracture, classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The current encounter is for ongoing management of the nonunion.

Use this code for follow-up encounters when a patient with a previously diagnosed displaced open fracture (Type IIIA, IIIB, or IIIC) of the left tibial spine is experiencing a nonunion. This implies that the fracture has failed to heal after an expected period. This code would be appropriate for visits related to assessing the nonunion, planning further treatment, or managing complications.

• Ensure documentation clearly states "nonunion" and specifies the left tibial spine.
• Verify the original fracture was an open fracture classified as Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter would use a different code.
