Pathological fracture, right femur, subs for fx w malunion

This code signifies a fracture of the right femur that occurred due to a pre-existing disease process, rather than trauma, and is currently in a healing phase with an unsatisfactory alignment of the bone fragments. The patient is receiving active treatment for the malunion during this encounter.

Apply this code when documentation indicates a patient is being treated for a right femoral pathological fracture that has healed in a misaligned position. This is appropriate for follow-up visits where the malunion is being addressed, such as through physical therapy, cast changes, or surgical planning for corrective osteotomy.

• Ensure documentation clearly specifies "pathological fracture" and "right femur."
• The 7th character "P" indicates a subsequent encounter for a fracture with malunion; do not use for initial treatment or routine healing without malunion.
• Always sequence this code after the underlying disease causing the pathological fracture (e.g., osteoporosis, neoplasm).
