Path fx in neopltc dis, l fibula, subs for fx w delay heal

This code signifies a fracture of the left fibula that occurred due to an underlying neoplastic process, and the patient is presenting for follow-up care because the fracture is not healing at the expected rate. This indicates a complication in the healing process of a pathological fracture.

Apply this code when documentation clearly states a pathological fracture of the left fibula, caused by a tumor, is experiencing delayed healing. This code is appropriate for subsequent encounters where the focus is on managing the delayed union of the fracture. Supporting documentation would include imaging reports showing incomplete healing and physician notes detailing the delayed healing status.

• Ensure documentation specifies "delayed healing" for the subsequent encounter.
• Always sequence the underlying neoplasm code first, followed by this fracture code.
• Distinguish from nonunion (M84.4-) or malunion (M84.3-) which represent different healing complications.
