Unfortunately my experience with UHC has been the same / worse. For my strips (which are chosen since the meter communicates with my pump but are the lowest tier in the UHC list), my co-pay is $80 for 90-day supply. (And $31-something for 90-days' supply of lancets. That's even more ridiculous, given how inexpensive those are.) Even with the medical necessity letter (which just allows me to purchase the brand I want), we just swallow and pay. Thankfully we can afford it.
If I were you, I would think whether you could do more strategically timed but slightly less frequent testing as a cost-saving measure. I do about 7-8 checks per 24 hours (when all is well of course) and have found that to be sufficient for great control.
At the same time, I would also try to find out from UHC what is their preferred way of ordering the strips. In my case, it turned out that if I bought them at the local pharmacy, the co-pay would be even higher. But by placing 90-day orders via their mail-order pharmacy, I am only charged the amounts listed above.
But it is a pain to deal with these for-profit insurance companies and you are right -- they don't give a XXX for us as patients. We are customers from whom they want to get the highest profit. Pure and simple.
