I am on straight Medicare with a supplement. Last October I had to visit the ER and spend one night in the hospital. I haven't received billing yet for the hospital or ER so I'm assuming that was covered. But I AM receiving bills from a private medical group and a private lab facility which again I assume are over and above the hospital and ER expenses. I have heard talking heads on TV rail about this clearly unfair practice, but am wondering (a) if it is still legal and legit and (b) if so, what options if any beyond just not honoring these bills I might have. Thanks in advance.
