Another exhume question: Does the entire casket go to the Medical Examiner then the body goes back to the morgue for makeup, clothing, etc., all over again?

I figure it’s got to be messy if the Medical Examiner removes the body from the coffin, does what he has to do, then puts it back. I suspect that makes all the “silk” inside the coffin messy. Does it get replaced? Do they put the clothes back on the body? Does it get new clothes? Is there another service with family?
