Path fx in oth disease, l foot, subs for fx w delay heal

This code signifies a pathological fracture of the left foot that occurred due to an underlying disease process, not trauma. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

Apply this code when documentation indicates a left foot fracture caused by a systemic condition (e.g., osteoporosis, metastatic cancer, Paget's disease) and the patient is receiving ongoing treatment for the fracture. This code is appropriate when the physician explicitly notes delayed healing during a follow-up encounter.

• Always sequence the underlying disease causing the pathological fracture first.
• Ensure documentation clearly specifies "delayed healing" for the subsequent encounter.
• Distinguish from nonunion or malunion, which have separate codes.
