has anyone won an appeal for lumbar ADR when considered "investigational"?

[LA gal]

Hello. I'm a newbie to this forum. To make a long story short, I have a dessicated L5 - S1 disk. My surgeon recommends ADR which I prefer over fusion; however, my insurance company BCBS of Louisiana has a policy against ADR stating that it is investigational. I decided to appeal. After a few weeks of research, I am a bit overwhelmed and could use some help. Has anyone ever won an appeal for lumbar artificial disk replacement when insurance labels it as "investigational"? If you have, would you be willing to share your appeal or pointers with me? I feel lost in the process of reading loads of articles; letters; opinions; studies; policies; court cases, and on and on. I would appreciate any assistance someone can offer. Thank you.
