Displ commnt fx shaft of l tibia, 7thN

This code signifies a complex, displaced comminuted fracture involving the shaft of the left tibia. It specifically indicates that the fracture was initially an open fracture (Type IIIA, IIIB, or IIIC) and is now being managed during a subsequent encounter due to a nonunion, meaning the bone is failing to heal properly.

Apply this code for patients presenting for follow-up care, surgical intervention, or ongoing management of a left tibial shaft fracture that was initially open and has progressed to a nonunion. This is appropriate when the patient is beyond the initial healing phase and the fracture has not united.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (left tibia) and the specific bone segment (shaft) are accurately documented.
• Do not use for malunion; a separate code exists for that complication.
