We have used Medicare along with the United Healthcare Plans through AARP for years.
Virtually no paperwork to fill out to use it and .... we walk out of hospital operating rooms, emergency rooms, and doctor's offices owing nothing ... anywhere in the U.S.A. - which is great if you want to travel all over in your RV.
I agree with posters above - it's pretty obvious that we need congress to once again get involved constructively (like they did for Medicare and Supplement Plans) and put the same type of controls in place to create the same kind of national uniformity of coverage for Prescription Drug Plans that we get with Supplement Plans!
