Start a conversation with me and Diana and email it to us. I don't know how to help you post it here.
I'm also thinking that if the ONLY reason they gave proves to be lack of medical necessity, and NOT that you don't have coverage for revisions, we would have a much easier time of it. Again, we need the written denial. If you can get it from your surgeon, fine, if not, we just have to wait for your copy to arrive. Our hands are tied without this.
I think Diana is away on her RV trip but she does check her emails and respond, it just takes a little longer. So again, a conversation, or email to the two of us, would be helpful.
