Path fx in oth disease, r tibia, subs for fx w malunion

This code signifies a fracture of the right tibia that occurred due to an underlying disease process, not from trauma. The fracture is currently in a state of malunion, meaning it has healed in an unsatisfactory position, and the patient is receiving ongoing care for this complication.

Apply this code for follow-up encounters where a patient is being treated for a malunited pathological fracture of the right tibia. Documentation should clearly state the fracture's pathological origin, its location, the presence of malunion, and that the encounter is for subsequent care.

• Ensure documentation specifies the underlying disease causing the pathological fracture.
• Distinguish between malunion (healed incorrectly) and nonunion (failure to heal); different codes apply.
• Always sequence the underlying disease code first, followed by this fracture code.
