I stopped cataloging the invoices after it hit $1.6M. Granted that's what the providers would bill my insurance, and we all know those are funny numbers, and while I'm sure that a concentrated effort to negotiate cheaper cash prices might have been productive, there's still the fact that I would have had to have $600k or so readily available. HYSA yields were pretty low for most of this time period, and if I had kept that kind of money in a stock portfolio, taxes would have killed me.

And it's beside the point. 99% of Americans can't afford to build a $600k nest egg just to cover medical expenses. THAT'S WHAT INSURANCE IS FOR!
