My wife have Medicare for c and d happy with it.
They will send you a catalog with various Advantage plans available in your area. If you are near a large metropolitan area, we have found that these are the way to go. You just have to take an hour or so to see what is available in your area.
We have traditional Medicare and United Healthcare Plan F as a supplemental. Have had very good success with this although the Plan F of today is not as good as what we got 20 years ago.
We went to seminar, then signed up for their service. Got the video link too.
Fee was very reasonable, especially since we went on Medicare 3 years apart.
This is the video they sent us when we made further inquiries. It’s outdated, but I’m sure they have updated ones, but the info is still every close to accurate. It’s 40 minutes that will answer most of your questions.
