I turn 65 next month and have been receiving tons of mail for Medicare. I can get totally confusing if you were to actually read it, which I don't.
We have an insurance broker and I make a phone call to him and he gets me signed up and will search the private insurers for the best plan for me.
Everybody is different and requires different plans and it depends where you live Lots of variables.
Brokers get paid on what they sell to you. To trust only one to do what is best for you could be a big mistake.
Yes, it's confusing, but refusing to educate yourself is the wrong way to go. Find someone to help who doesn't have a financial or any other interest in what you choose. There are Medicare advocates who can help. Just don't work with one who calls themselves that when they are really an insurance agent.
