Medical coverage

I've gotten an email that some folks are having trouble with their KR medical coverage. Has anyone gotten different, worse coverage in 2005 compared to previous years? I know that some of us who retired after 1996 are more susceptible to coverage changes than others. But if something serious is going on, we'll need to get to the Guild folks in Cleveland to see what can be done about it. I have only had prescription refills and there are no changes in that ($2 co-pay) once the January flurry of errors was straightened out. But I haven't had anything, fortunately, involving doctors except what Medicare covered.
