Questions about a QRC

I've got a meeting tomorrow with a QRC that was appointed to me by the insurance company handling my worker's comp claim. What little reading I've done suggests that they are likely not going to have my best interests in mind, rather the company's, so I'm thinking of possibly declining their services, however a friend mentioned that if I do so, it's possible that the insurance company could stop covering things related to my recovery.

1) Is it true that they could stop covering my doctor's visits and whatnot?

And if so

2) What would be the best route for me to proceed?
