Pathological fracture, unsp ankle, init encntr for fracture

This code signifies a fracture of an unspecified ankle that occurred due to an underlying disease process, rather than trauma. The bone was weakened by a condition such as osteoporosis, metastatic cancer, or osteomalacia, leading to the fracture with minimal or no force. This code is specifically for the initial treatment phase of the fracture.

Apply this code when documentation clearly states an ankle fracture is pathological and the specific ankle (right or left) is not identified. This is appropriate for the initial encounter where the patient is receiving active treatment for the fracture. Supporting documentation includes physician notes detailing the pathological nature of the fracture and the treatment plan.

• Ensure the documentation explicitly states "pathological fracture" and that the ankle is unspecified.
• Do not use this code for traumatic fractures; those are coded differently.
• Always sequence this code first, followed by codes for the underlying disease causing the pathological fracture.
