For folks in Massachusetts - what are your experiences with Medicare and all the various parts and supplements in our state? is It possible that the meds are covered including rituxin and which insurance supplement is neended for this. I am starting to read up on the info and it is a bit confusing to me and I know that good coverage is important for us and I also know that I have learned that folks here have very helpful information. Also - can a person continue with the insurance they had when they were working and add Medicare on also. Any help much appreciated. Thanks
