Why do we have to do the health insurance company's job for them?
Just so tired of almost every time a doctor submits stuff to insurance, we have to be the ones to make multiple phone calls to both the doctor's office and insurance to iron everything out, figure out what the issue is (it's always a different issue), and basically be the go-between for the office and insurance. What am I paying $500+/month for?! It's like paying for the privilege of having an exhausting part-time job.
And yes, I understand that insurance wants to weasel out of paying anything, but this isn't even shadiness, just straight up incompetence and lack of communication/following procedures. The amount of emotional energy we have to spend untangling this stuff leaves us drained.
If you fail to run the gauntlet, or give up in frustration, the insurance company doesn't have to pay. They could absolutely make this process easier, but the incompetence works in their favor.
I've lived in single payer countries as well as in the US, and the incompetence is the same everywhere. In my experience the big difference is in universal healthcare countries the rules are very strictly defined and there's very little scope for exceptions, so either you qualify or you don't. The other issue is that even if you qualify there's often a multi-month waiting list for treatment.
