Or really any other company that jerks you around for profit?

Real question.

Every single time I interact with my healthcare, they drag me through some maze of processes where they're just waiting for some minor clerical error so they can deny a claim. Then like, they'll "screw up" and deny a claim through multiple rounds of review, only to approve it 6 months later after sucking away weeks of my life fighting it.

The maze they set up has me going to places multiple times, and getting turned away because X doctor isn't in Y system because it's two separate systems that are not meant to go together, but they were the cheapest options so my insurance will only cover them.

I actually need a better way to cope with this because I'm putting off healthcare because I dread the fight. And whenever I'm fighting it, I'm just picturing myself trying to fight claims when I'm fighting cancer on chemo or something and I just don't know how I'd manage.

How do you all manage? (if you even have healthcare at all)
