For some reason they are more willing to treat alcohol inpaitent then if its just drugs. I was told that you wont die from opiate detox you will just feel like your going to but you can die from benzo's and booze. They really said this I had the rehab talk to the insurance co they know what to say.
I realize that treatment is expensive and doesnt always work but these companies make it very hard. If you paid your premiums for 30 years and this is the first time you need service they should have to provide it for you.
My insurance co is very slippery they gave the rehab an ok then refused payment I'm still fighting it more then 3 yrs later
Good luck to you and your son
