We've been on UHC Advantage since we retired and are happy with it. We use all the wellness benefits they offer, as well as the vision and dental.
Yes, UHC Advantage plans differ by state and even by county, although not a lot.

We were on it in Indiana but switched to The Villages UHC Advantage when we moved here last year. We like The Villages Health system and had no problem getting a PCP. Appointments are easy to get since they limit how many patients a doctor can have, and only take MA plans. So we never sit in the waiting room more than 15 minutes before we get called back. Take a tour of their facility. They have them all throughout The Villages.

MA plans are a good option, over 50% of new enrollees choose them. But it's not a one size fits all as some like to make you think. For some, regular Medicare is the best way to go.

Not all MA plans are the same, some are better than others. Do your research, check the ratings and as others have said, talk to SHINE.
SHINE told us Medicare Advantage was a very good option for us.

No, not every single hospital or doctor takes UHC MA. But we did our research, and many excellent hospitals do take it, including UF Shands and Advent Health in Orlando.
