I had UHC for one year and they denied my long standing MS med that I had been on for 9 years because "we don't know if you need to be on it" despite my doctors insisting I do. Because of that I was off my meds for a year and a half and ended up changing medication. The company who made the original med I was on, Novartis, also just ignored all my phone calls so that's why I wasn't allowed to get back on my med even with it being denied. Usually the company has a program that helps but with them not responding I was fucked.
And UHC refused to do anything to help.
Fuck UHC.
