Pathological fracture, left femur, subs for fx w routn heal

This code signifies a fracture of the left femur that occurred due to an underlying disease process, rather than trauma. It indicates that the patient is in the healing phase of this pathological fracture, and the healing is progressing routinely without complications.

Apply this code for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed pathological fracture of the left femur. Documentation should confirm the fracture's pathological origin, specify the left femur, and indicate that healing is proceeding as expected. This code is appropriate for visits such as cast changes, follow-up X-rays showing callus formation, or physical therapy during the routine healing period.

• Ensure documentation clearly states the fracture is "pathological" and specifies the left femur.
• The "D" seventh character indicates a subsequent encounter for routine healing; do not use for initial treatment or delayed/nonunion healing.
• Always code the underlying pathological condition (e.g., osteoporosis, neoplasm) first, followed by this fracture code.
