Displ commnt fx shaft of unsp femr, 7thN

This code signifies a complex, displaced comminuted fracture of the femoral shaft where the bone is broken into multiple fragments and the ends are not aligned. It specifically indicates an open fracture (bone exposed to the outside) of severe type (IIIA, IIIB, or IIIC) that has failed to heal properly (nonunion) and is being treated in a subsequent encounter.

Apply this code when documenting ongoing treatment for a patient with a previously diagnosed, severely comminuted and displaced open fracture of the femoral shaft that has developed nonunion. This is appropriate for follow-up visits, surgical interventions for nonunion, or other management of the unhealed fracture after the initial acute treatment phase.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify this is a subsequent encounter, not the initial treatment for the acute fracture.
• Confirm the fracture is of the femoral shaft and not another part of the femur.
