Displ Maisonneuve's fx r leg, subs for clos fx w malunion

This code signifies a specific type of fracture in the right lower leg, known as a Maisonneuve's fracture, which involves a spiral fracture of the proximal fibula with associated ankle injury. The fracture fragments are no longer in their correct anatomical alignment (displaced), and the bone has healed incorrectly (malunion). This particular code is used when the patient is receiving follow-up care for this previously treated but now malunited closed fracture.

Apply this code for patients presenting for evaluation or treatment of complications arising from a malunited Maisonneuve's fracture of the right leg. This includes scenarios such as pain, deformity, or functional limitations due to the improper healing, during a subsequent visit after the initial treatment. It is appropriate when the fracture was initially closed and has now healed in a misaligned position.

• Ensure documentation clearly states "malunion" and "displaced" for the Maisonneuve's fracture.
• Verify the encounter is for follow-up care of the fracture, not initial treatment or active healing.
• Confirm the laterality is specifically "right leg" and the fracture was "closed."
