Disp fx of unsp tibial spin, 7thN

This code describes a displaced fracture of an unspecified tibial spine that has failed to heal properly, resulting in a nonunion. It specifically applies to open fractures classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This code is used for follow-up care after the initial treatment of the fracture.

Use this code when documenting subsequent encounters for a patient with a previously diagnosed displaced open fracture (type IIIA, IIIB, or IIIC) of the tibial spine that has not united. This includes situations where the patient is undergoing ongoing treatment, monitoring, or surgical intervention for the nonunion.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is of the "tibial spine" and not another part of the tibia.
