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

This code signifies a fracture of the left shoulder that occurred due to an underlying neoplastic (cancerous) process, and which is now being treated for a malunion. A malunion indicates that the fracture has healed, but in an unsatisfactory or deformed position. This code is used for subsequent encounters after the initial treatment of the fracture.

Apply this code when a patient with a known malignancy presents for follow-up care of a left shoulder fracture that has healed incorrectly. Documentation should clearly state "pathological fracture," specify the left shoulder, confirm a malunion, and indicate that this is not the initial treatment encounter. This code is appropriate for ongoing management, rehabilitation, or planning for corrective procedures related to the malunion.

• Always sequence the underlying neoplasm code first, followed by this code, as the fracture is secondary to the cancer.
• Distinguish carefully between nonunion (failure to heal) and malunion (healed incorrectly); different codes apply.
• Ensure the documentation specifies "left shoulder" and not just "shoulder" to support laterality.
