M84.664S
ICD-10-CMThis code signifies a pathological fracture of the left fibula that has occurred due to an underlying disease process, rather than trauma, and is now being addressed as a sequela or late effect. This indicates that the initial active treatment for the fracture has concluded, and the patient is experiencing residual effects or complications.
Use this code when documenting a patient presenting with a long-term complication or residual condition directly attributable to a previously healed or treated pathological fracture of the left fibula. This is appropriate when the underlying disease causing the fracture is no longer active or is being managed separately, and the focus of care is on the lasting impact of the fracture. Documentation should clearly state "sequela," "late effect," or describe a chronic condition resulting from the fracture.
