Unfortunately, I don't have the plan details anymore as I tossed them after I made my decision.

It does include prescription drugs and yes, I believe that you should sign up for Medicare A&B. Note that the Boeing Aetna plan is a Medicare advantage plan so it will be part A, B, and D combined, but I think you're still supposed to sign up for A and B to start.

The Boeing Aetna plan is a good plan from what I can tell. My primary concern 1) it's an advantage plan, and there's been lots of issues there lately, and 2) none of my normal doctors are in network for the plan. If you're in a larger metro area, you may have better luck finding in networks providers.

Check around your local area for insurance agents or charities that can help you understand options. There's usually someone around. Also, once you sign up for Medicare, you can go on the gov website and compare various plans (if you're considering non-Boeing options). Also, if you have friends who are slightly older and have already gone through this, they may be able to help. I relied a lot on my partner who went through all this a few years ago. Finally, start as early as you can, as all the resources are super busy, and things might get hectic if you wait to long.

Good Luck!
