M96: Postprocedural musculoskeletal disorders, not elsewhere classified

M96.6: Fracture of bone following insertion of orthopaedic implant, joint prosthesis, or bone plate

You had an operation on a bone or a joint. An operation like this can involve plates or artificial joints being attached to the bone, for example. This can exert strong pressure on the bones. It can result in bones being broken. This can particularly occur if the bones are already diseased or damaged.
