At my age with medicare "advantage" plans I have found they are denying procedures & going for lower cost treatment. The good health care is no longer accepting their coverage. This is not my experience but that of many others around me.
Yes, I am one of the older ones & going to an MD doesn't work for me because of the horrible reactions I have to drugs including antibiotics. So I just avoid them all together. Problem is that insurance does not cover natural treatments when I really do get sick with something.
I have found unethical behavior in many other areas I am dealing with & it is wearing on my patience & making everything take longer to be resolved
