Jjames,

I would see if your insurance can really deny you treatment after an "unapproved" or "not certified" surgery. I think they are going beyond what it says in their policy book. If your policy book does not say that then they shouldn't be able to do that.
Even my crappy insurance pays for my post-ADR treatment.

I have seen this before and I think this is illegal.
Health insurance sucks but they do have some obligations especially when you or your company is paying for a service.

I ditto all of the above, too. Fight. I did and got my surgery approved and then I fought some more when BC did not pay for it.
Do not give up and throw up your hands and throw in the towel.
I don't know your exact circumstances but there are resources out there to help you.
