Path fx in neopltc disease, l fibula, subs for fx w malunion

This code signifies a fracture of the left fibula that occurred due to an underlying neoplastic (cancerous) process, which has subsequently healed improperly (malunion). It indicates that the patient is receiving ongoing care for this specific complication of their cancer.

Apply this code when a patient presents for follow-up care, rehabilitation, or management of a left fibula fracture that is a direct consequence of cancer, and the fracture has healed in an unsatisfactory alignment. Documentation should clearly state the neoplastic etiology of the fracture, the specific bone involved, and the presence of malunion during a subsequent encounter.

• Always sequence the underlying neoplasm code first, followed by this code.
• Distinguish between nonunion (failure to heal) and malunion (improper healing) based on provider documentation.
• Ensure the encounter type (initial, subsequent, sequela) is accurately reflected in the 7th character.
