An autopsy can run you big money. Private autopsy is very expensive. If not ordered or required by law the family will have to pay, in advance cash or money order.

A partial( meaning they have a good idea what caused it and aren't examining all organs and tissues starts at about 5500$ here. Not including transport either way.

Full is about 8000. If specialist are required then you will also have to pay them for their time in advance. It's about 1500$ if they do that. Then you have to pay for a funeral.

Trust me I have helped set up about 8 of these. Most families say they want one and then when they hear the price are like "nah we good". I deal with death a lot in my job. Very rare they actually need a autopsy unless murder, or are young with no medical history Toxicology is done pretty commonly
