Pathological fracture, unsp site, subs for fx w malunion

This code signifies a pathological fracture, meaning a fracture that occurred due to a disease process weakening the bone, rather than trauma. Specifically, it indicates that the patient is in a subsequent phase of care for this fracture, and the bone has healed in an abnormal alignment (malunion).

Use this code for follow-up encounters when a patient's pathological fracture, at an unspecified anatomical site, has healed with malunion. Documentation should clearly state the pathological nature of the fracture, the presence of malunion, and that the encounter is for ongoing management or evaluation of this complication.

• Ensure documentation specifies "pathological fracture" and "malunion" for accurate code assignment.
• Do not use this code for initial encounters or for fractures healing normally.
• Always sequence this code after the underlying disease causing the pathological fracture, if applicable and still active.
