Displ spiral fx shaft of unsp tibia, 7thN

This code describes a fracture involving the shaft of the tibia, where the bone fragments are no longer in their normal alignment and the fracture pattern is spiral. It specifically indicates an open fracture (meaning the skin and soft tissues are also compromised) classified as Type IIIA, IIIB, or IIIC, and that the bone has failed to heal after a typical period (nonunion). This code is used for follow-up care after the initial treatment of the fracture.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed open spiral fracture of the tibial shaft that has developed nonunion. This includes follow-up visits for ongoing management, surgical intervention for the nonunion, or evaluation of complications related to the nonunion. It should be used when the specific type of open fracture (IIIA, IIIB, or IIIC) is documented.

• 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 shaft and described as spiral and displaced.
