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

This code signifies a right ulnar fracture that occurred due to an underlying neoplastic process, and the patient is now presenting for follow-up care where the fracture has healed incorrectly (malunion). This indicates a complication in the healing process of a pathological fracture.

Use this code for patients with a documented right ulnar malunion following a pathological fracture attributed to cancer, who are receiving ongoing treatment for the fracture. Documentation should clearly state "malunion" and specify the right ulna and the neoplastic etiology.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure documentation explicitly states "malunion" and not just "nonunion" or "delayed union."
• Verify the laterality (right) and bone (ulna) are precisely documented to support this specific code.
