We have had Medicare Advantage plans for three years and are happy with results so far. First two years we had United Health Care Secure Horizon and this year changed to Blue Cross/Blue Shield (called Blue Medicare PPO). We changed because Secure Horizons increased the price for primary care doctor visit as well as Specialist care. Both plans have a lot of hospitals and doctors under their umbrella and both had good prescription drug coverage. We are really happy with BCBS Medicare Advantage plan. One big thing to consider is that if you have any existing conditions that might require more/future serious care(like me), once you're in an Advantage plan, you can't just go back to Medicare and a supplemental plan. Still, it's nice not having to pay any kind of premium other that your Medicare premium. Also, look for the maximum out of pocket cost/year for which you are responsible. For personal reasons, we decided we would never consider an HMO. And we really don't know what will happen in 2014 do we?
