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

This code signifies a fracture of the left ulna that occurred due to an underlying neoplastic (cancerous) process, and the fracture is currently failing to heal properly (nonunion). This indicates a chronic and complicated healing process for a fracture caused by a tumor.

This code is appropriate for encounters where a patient is receiving ongoing treatment for a left ulnar fracture that developed secondary to cancer, and the fracture has been diagnosed as a nonunion. Documentation should clearly state the neoplastic origin of the fracture, the specific bone involved (left ulna), and the nonunion status.

• Ensure documentation specifies "pathological fracture" and the underlying neoplastic disease.
• Verify the laterality (left) and the specific bone (ulna) are clearly documented.
• Confirm the "subsequent encounter" and "nonunion" status are explicitly stated or clearly implied in the medical record.
