Great, our health insurance through my wife's employer just switched from Blue Cross/Blue Shield over to United Healthcare on January 1.......
I was on Medcaid and somehow got defaulted to UHC for whatever reason(I thought I picked Maryland Physicians Care) and I couldn't change out. This was before mom getting Medicare Advantage.
Nevertheless, I got a laceration, and well, I took a couple lessons from attempting to get care. One, many docs don't take it because they're a bitch to docs too.
First doc, they ordered some bloods, but that was about it. Referred me to a specialist, but the specialist doc doesn't take it.
Second Doc, well, again, they ordered some bloods, but again, their referred docs don't take it. Eventually, I just wore out and stopped trying. Also, they denied my doc's claim at first and he was able to successfully appeal. While not responsible for payment, these events gave me a "sense" that something was rather deficient about UHC.
They're publicly traded, so every attempted denial is treated as an opportunity to keep the money to themselves.
I mean, they denied capecitibine(approved and covered under Medicare Part B) for my mom on the day or just a few days before the infusion was to start. So the Medstar Pharmacy basically paid UHC rather than bother appealing the decision. $$$ made, basically. I wrote out an appeal and UHC approved it, but ultimately, the Pharmacy was the one that had to go through with the demand of returned payment, and I think the Pharmacy did not.
Also, the UHC directory is a load of bull. Most of the docs listed may take an upper tier plan but not the "Community Plan". Since your insurance is employer-based and not Medicaid/Medicare, things may be a bit less obstructive, but this issues may still present themselves because of the stock market incentives.
