Pathological fracture in neoplastic disease, unsp foot, init

This code signifies a fracture of an unspecified bone in the foot that has occurred due to an underlying neoplastic (cancerous) process, rather than trauma. The bone has been weakened by the presence of a tumor, leading to a fracture with minimal or no force. This code specifically indicates the initial treatment encounter for this fracture.

Apply this code when documentation clearly states a pathological fracture of the foot, without specifying a laterality (left or right) or a specific bone, and attributes it to a neoplastic disease. This is appropriate for the first visit where the fracture is diagnosed and treatment begins. Supporting documentation includes imaging reports confirming a fracture and pathology reports or clinical notes indicating a primary or metastatic tumor as the cause.

• Always sequence the underlying neoplastic disease code first, followed by this code.
• Ensure documentation specifies "pathological fracture" and links it to a neoplastic process; otherwise, a traumatic fracture code may be more appropriate.
• If the specific foot (left or right) or bone is known, a more specific M84.57- subcategory code should be used.
