Path fx in neopltc dis, r humerus, subs for fx w nonunion

This code signifies a fracture of the right humerus that occurred due to an underlying neoplastic (cancerous) process, which has subsequently failed to heal properly (nonunion). It indicates that the patient is receiving ongoing treatment for this unhealed pathological fracture.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a right humeral fracture caused by cancer, and the fracture has not united. Documentation should clearly state "pathological fracture," "neoplastic disease," "right humerus," "nonunion," and indicate a "subsequent encounter" for this condition.

• Always sequence the underlying neoplasm code first, followed by this code.
• Distinguish carefully between nonunion (failure to heal) and malunion (healed in a poor position).
• Ensure documentation specifies the laterality (right) and the bone involved (humerus).
