Displ commnt fx shaft of r tibia, 7thM

This code describes a complex fracture of the right tibia's main shaft, where the bone has broken into multiple fragments and is out of alignment. It specifically indicates that the initial injury was an open fracture (Type I or II), and the bone has failed to heal properly, resulting in a nonunion.

This code is appropriate for follow-up encounters for patients with a previously diagnosed displaced comminuted open fracture (Type I or II) of the right tibial shaft who are now experiencing nonunion. This would typically be used when the patient is receiving ongoing treatment for the nonunion, such as surgical intervention, bone grafting, or prolonged immobilization.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the initial open fracture type (I or II) was documented, as this is crucial for code selection.
• Do not use this code for initial encounters or for malunion, which is a different complication of fracture healing.
