Is it even worth it to file a complaint to my insurance provider? (United Heath, NC)

I finally qualified for insurance through my employer, and for that I am grateful. However, I feel like I am living in a nightmare now that I having United Health Care after years of having BCBS. I really wish there was a way for me to return to BCBS, but I can’t afford an individual plan.

I was diagnosed with Chron’s Colitis 9 years ago, and I have been in remission for maybe 6 or 7 years now, thanks to the infusions that I get every 8 weeks. Just like UHC, BCBS required prior authorization of my medication, but it was fairly painless as the authorizations were always approved for about a year each time.

I am having an opposite, much more painful experience with UHC. Not only will they not allow the only hospital that I’ve gone to since I was born to purchase my medication, but they are forcing me to switch to a biosimilar, after years of living a totally asymptomatic life with no active disease in my body. I’m not too concerned about the biosimilar, but I am extremely concerned that UHC only authorized my medication for less than three months, even though I get infusions every 8 weeks. I went from going having the mental peace and security of having my treatments approved for a year, to now having to constantly worry every two months about having access to my life changing medicine. I feel so helpless and terribly anxious that this is my new normal. I am more dependent on health insurance than most people because I can’t afford my medication or treatment without it, and my hospital will not allow me to continue treatment without some sort of coverage.

Even though this situation seems totally out of my control, I can’t help but feel the urge to complain or advocate for myself further. I know my situation is nothing special and that a lot of people share my struggle in getting access to their medication, but I can’t see how sitting back and taking it is helping. Would it even be worth it to complain to UHC about my situation? I’m thinking about writing a letter. If anyone has another other advice about my situation, I’m really unsure how to make my situation better so I’d love to hear your thoughts.
