Unsp fx l low leg, subs for opn fx type 3A/B/C w malunion

This code describes a previously sustained, unspecified fracture of the left lower leg that was an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, and is now presenting with malunion. Malunion indicates that the fracture has healed, but in an unsatisfactory or deformed position. This code is used for follow-up care related to this specific complication.

This code is appropriate for encounters where a patient is being treated for a left lower leg fracture that has healed incorrectly, and the original injury was a severe open fracture. This would include clinic visits for assessment of the malunion, planning for corrective surgery, or post-operative care following intervention for the malunion. It signifies that the malunion is a current problem being addressed.

• Ensure documentation clearly specifies "malunion" as the current complication of the healed fracture.
• Verify the original fracture was an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture or malunion.
