The plan at this point is to just ignore it and hope it goes away, since they can't put it on your credit anymore.
What?
I'm sorry what kind of kaska-esque system is this?!
It's the system that us Americans are tricked into believing is the best and nOt sOciAlIsM. Certainly USA healthcare is "the best" — if you can afford it!
My personal belief is that the kafkaesque nature of so many systems is designed to keep people destitute and despondent — to quote ole TedK: "our system keeps people demoralized because a demoralized person won't fight back."

Having dropped out of a US medical school (almost two decades ago), I can assure you things have only gotten worse (from a bottom 80% POV). My best method of pyhhric victory is to not reproduce, earn just enough to live minimally (i.e. lessen tax burden/revenue), and never pay for health insurance.
YMMV — I quit, a long time ago.
