Path fx in oth disease, r femur, subs for fx w malunion

This code signifies a right femur fracture that occurred due to an underlying disease process, rather than trauma, and is currently being treated for a complication of malunion. Malunion indicates that the fracture has healed, but in an unsatisfactory position or alignment, potentially leading to functional impairment. This specific code is used for follow-up care related to this malunited pathological fracture.

Use this code for patients presenting for ongoing management, evaluation, or treatment of a malunited pathological fracture of the right femur. Documentation should clearly state the pathological nature of the fracture, its location (right femur), the presence of malunion, and that the encounter is subsequent to the initial fracture treatment. This code is appropriate when the patient is still receiving active treatment for the malunion or its complications.

• Ensure documentation specifies "pathological fracture" and the underlying disease causing it (e.g., osteoporosis, neoplasm).
• Verify that the encounter is for subsequent care of the malunion, not initial treatment or routine follow-up of a healed fracture without complications.
• Always code the underlying disease responsible for the pathological fracture first, followed by this code.
