Path fracture in neoplastic disease, left fibula, sequela

This code signifies a long-term complication or late effect resulting from a pathological fracture of the left fibula, which was caused by an underlying neoplastic (cancerous) disease. It indicates that the patient is experiencing ongoing issues directly attributable to the previous fracture and its etiology.

Apply this code when a patient presents for follow-up care, rehabilitation, or management of a chronic condition directly related to a healed or resolving pathological fracture of the left fibula due to cancer. Documentation should clearly state the "sequela" or "late effect" of the fracture, and link it to the neoplastic disease.

• Always sequence this code after the code for the underlying neoplastic disease (e.g., C79.51 for secondary malignant neoplasm of bone).
• Ensure documentation specifies "left fibula" and confirms the fracture was due to neoplastic disease, not trauma.
• Distinguish from active pathological fractures (M84.5- without the 'S' seventh character) which are used for initial or active treatment phases.
