Path fx in neopltc disease, r ulna, subs for fx w nonunion

This code signifies a pathological fracture of the right ulna, meaning the bone broke due to an underlying neoplastic (cancerous) process, rather than trauma. The "subsequent encounter" indicates the patient is receiving active treatment for the fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Use this code for patients presenting for follow-up care, surgical intervention, or other active treatment related to a right ulnar fracture caused by cancer, where the fracture has not healed. Documentation should clearly state a pathological fracture, identify the right ulna, confirm nonunion, and indicate a subsequent encounter for fracture care.

• Always sequence the underlying neoplasm code first, followed by this fracture code.
• Distinguish carefully between "subsequent encounter for fracture with nonunion" and "subsequent encounter for fracture with malunion" or "routine healing."
• Ensure documentation specifies the laterality (right ulna) and the pathological nature of the fracture.
