You literally say it in your own reply. “Sometimes medically necessary”. If you think nearly everything isn’t classified as that by a company who makes more money the more healthcare they don’t cover I don’t know what anyone can say to you to bring you back to the reality of US healthcare. They hire unemployable doctors with histories of malpractice to deny claims in bulk.
I did. It was truly unfortunate. After working in healthcare for a decade I thought i had seen all possible shit takes…I was wrong lol.
