Okay, as someone ON Medicare...
First, are you still covered on your spouse's insurance?
IF NOT, get an advantage plan, either a PPO or an HMO (NOT a PFFS one). Reason being, with JUST Medicare, you only get A & B...and are still responsible for the 20% that Medicare will not pay. AND you have to have Plan D as well, the prescription part.
IF you are, then Medicare will be secondary to your spouse's insurance as long as your spouse is working. And after that insurance covers all your medical, Medicare picks up the 80% of what is left.
Confused yet?
Example, say you are a dependent on another insurance that is primary to Medicare and as long as your spouse is gainfully employed and can carry you on his insurance, then Medicare remains secondary..
His/yours would be insurance A and insurance A pays 85% of your medical services:
You end up having surgery....cost is 20K (a made up number). Insurance A pays 85% or 17,000. That leaves a balance of 3,000. Medicare then pays 80% of the 3K. That means they would pay 2400. THAT leaves a balance of 600 that you would have to pay.
The rules are different if both your spouse and you are retired. but given the 1985 on your user name, I am assuming you aren't of retirement age yet.
If you are single, then YES, YES, YES, get a Medicare Advantage plan.
