Is it possible to have damage repaired on my iPhone body (case)?

I've dropped my iPhone 6S on the floor and the screen has cracked, I'm having it repaired on Monday but I was wondering how much it would cost to have the body (case) repaired at the same time, as it has some dents and scratches on it?

Thanks for your help.

P.S. I'm talking about the phone itself, not a separate case

You'd need a new case. Ask the people repairing it to quote
