@ucfsig Best thing is to have the doctor fight for it. If they recommend it to the insurance company and show evidence to the insurance company why they believe it's the best option and the benefits for it. My oncologist has had to fight my insurance company over pretty much everything he wanted to do. Insurance didn't want to cover the targeted cancer medication, didn't want to cover the genetic testing, didn't want to cover the proton beam radiation, didn't want to cover my pain pills...etc...etc. At the beginning of my diagnosis and treatment process it was just constant denial letters arriving. I would bring them in to my oncologist and he would be so angry and have to call them up and demand to speak to the doctors at the insurance company. Asking them how they could possibly claim to know what is better for his patient. They would then cave and agree to the prior authorizations to cover it. I have found that having a great doctor who is willing to fight for you is very important. If you find that they are not willing to advocate for you, switch doctors.
