Are Catholics expected to bury amputated body parts in a cemetery?

I remember seeing, some forty years ago, the Catholic family of a cancer patient burying his amputated leg in the local cemetery. I do not know if Christians all over the world still practice such burials. My question is: are there instructions in the Catholic Canon Law or in other texts making it mandatory for the faithful to bury the body parts amputated on account of accident or surgery, in a consecrated cemetery?
