Pathological fracture, right foot, subs for fx w nonunion

This code signifies a fracture in the right foot that occurred due to an underlying disease process, rather than trauma, and has failed to heal properly. The "subsequent encounter" indicates the patient is receiving active treatment for this unhealed pathological fracture.

Use this code for follow-up visits where a patient is being treated for a right foot fracture that was caused by a condition like osteoporosis or a tumor, and the fracture has not united. Documentation should clearly state "pathological fracture," "right foot," and indicate nonunion or delayed healing requiring ongoing treatment.

• Always sequence the underlying disease causing the pathological fracture (e.g., osteoporosis, neoplasm) before this code.
• Ensure documentation specifies "nonunion" or "delayed union" for subsequent encounters; otherwise, a different subsequent encounter code may be more appropriate.
• Distinguish from traumatic fractures; this code is specifically for fractures due to disease.
