I literally just had my first one. I’m not sure about every doctor but my doctor wouldn’t even submit to insurance until now. He said they would deny until we have evidence that I had tried other methods and they had failed. You also have to have like 10+ migraines a month. I don’t really have migraines, I get tension headaches many days and then maybe 1-2 migraines a month but he submitted them as migraines.Let me know how it goes for you. How many rounds in are you?
