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

This code signifies a pathological fracture of the left foot that has occurred due to an underlying neoplastic (cancerous) process. The fracture has failed to heal properly, resulting in a nonunion, and the patient is receiving follow-up care for this complication.

Apply this code when documentation clearly indicates a left foot fracture caused by a tumor, and the patient is presenting for ongoing treatment of a confirmed nonunion of that fracture. This code is appropriate for subsequent encounters after the initial treatment of the fracture. Documentation should specify the neoplastic disease and the nonunion status.

• Always sequence the underlying neoplastic disease code first, followed by this code.
• Ensure documentation explicitly states "nonunion" for the fracture; otherwise, a different subsequent encounter code for routine healing may be more appropriate.
• Verify the laterality (left foot) and the type of encounter (subsequent for nonunion) are clearly documented to support this specific code.
