Nondisp bimalleol fx l low leg, subs for clos fx w malunion

This code signifies a left lower leg fracture involving both the medial and lateral malleoli, which are the bony prominences on either side of the ankle. The fracture fragments are in their anatomical position (nondisplaced), but the bone has healed incorrectly, resulting in a malunion. This code is used for follow-up care after the initial treatment of the fracture.

Apply this code when a patient presents for ongoing management of a previously treated, nondisplaced bimalleolar fracture of the left lower leg that has healed in an unsatisfactory alignment. This includes scenarios such as physical therapy, follow-up imaging, or evaluation for corrective surgery due to the malunion. It is appropriate for any encounter after the initial active treatment phase.

• Ensure documentation clearly states "left lower leg," "bimalleolar," "nondisplaced," and "malunion."
• The "P" seventh character indicates a subsequent encounter for a closed fracture with malunion.
• Do not use this code for initial treatment or for open fractures.
