Fx tib/fib fol insrt ortho implnt/prosth/bone plt, left leg

This code describes a fracture of the left tibia or fibula that occurs after a patient has undergone surgery to implant an orthopedic device such as a joint prosthesis, bone plate, or other internal fixation device. This fracture is a complication directly related to the presence of the previously implanted hardware.

Use this code when documentation clearly indicates a new fracture of the left lower leg bones (tibia or fibula) in a patient who has a pre-existing orthopedic implant in that same leg. This typically applies to periprosthetic fractures or fractures occurring around or through existing hardware. Supporting documentation includes operative reports of the initial implant surgery and imaging/clinical notes confirming the subsequent fracture.

• Always confirm the laterality (left leg) and the specific bone involved (tibia or fibula).
• Ensure the fracture is explicitly stated as occurring after the insertion of an orthopedic implant, not an acute fracture unrelated to prior hardware.
• Do not confuse with codes for nonunion or malunion of a previous fracture, or acute traumatic fractures without a pre-existing implant.
