Path fx in oth disease, l fibula, subs for fx w routn heal

This code signifies a fracture of the left fibula that occurred due to an underlying disease process, not from trauma. The patient is currently in a subsequent phase of care, and the fracture is healing as expected without complications.

Apply this code when documentation confirms a left fibular fracture caused by a systemic condition (e.g., osteoporosis, metastatic cancer) and the patient is returning for follow-up during the routine healing period. The medical record should clearly state the pathological nature of the fracture and the encounter type.

• Ensure the underlying disease causing the pathological fracture is also coded and sequenced appropriately.
• Verify laterality (left fibula) and the encounter type ("D" for subsequent encounter, routine healing).
• Do not use for stress fractures or fractures due to direct trauma; those have different code categories.
