Pathological fracture, left shoulder, subs for fx w malunion

This code signifies a fracture of the left shoulder that occurred due to an underlying disease process, rather than trauma, and is currently being treated for a complication where the bone has healed in an abnormal position. This indicates ongoing management of a previously sustained pathological fracture with a documented malunion.

Apply this code when a patient presents for follow-up care, rehabilitation, or further intervention related to a pathological fracture of the left shoulder that has healed incorrectly. Documentation should clearly state "pathological fracture," specify the left shoulder, and explicitly mention "malunion" in the context of a subsequent encounter.

• Ensure documentation specifies "pathological fracture" to differentiate from traumatic fractures.
• Verify the encounter is for ongoing care of the malunion, not the initial treatment or routine healing.
• Always sequence this code after the underlying disease causing the pathological fracture, if applicable and still active.
