Carriers and providers don't make this easy, either.

I had a recent doctor's visit, with very good healthcare coverage, that was an in-network facility but an out-of-network provider. Coverage would have kicked in if I had a referral from my PCP, but my PCP recently retired and I was advocating for my own health for a small dermatological issue. They said it was cosmetic, my old PCP said it was not. I got a stack of 10 bills over many months all stating different things -- everything from $0 EOB to over $2k in uncovered expenses. No one would take ownership of sorting out what I was on the hook for. No one I talked to was empowered to actually solve it. It wasn't an affordability problem over $2k (but would be for my elderly grandparents on fixed income). Even asking "If I give you $2k does that resolve the debt?" was answered with "we won't know until we apply the payment" type non-answers.

Burn the whole stack down -or- earn enough you can operate on cash for the tier of care you want. Nothing inbetween seems to be working.
