I didn't initially since I wasn't on any prescriptions. But when they added a penalty for not having a Part D Rx plan, I went back and added one of those. I simply chose the cheapest one available in SD since I wasn't on any Rx and was only paying for that policy it to avoid the penalty.
I would be happy to share, but I didn't need or use an agent. I signed up for Medicare and my Supplement using www.medicare.gov website. It gives you everything you need, a link to sign up online for medicare itself, which is the same for all regardless of your home state. Then for supplements you enter your new domicile zip code and it will list the supplement options available.
Sorry, folks...new to using this network and not sure I'm doing it all correctly!
Jim...JRP... would you be willing to share your agent's name and number in SD? I know that when we sell our house and establish our new domicile, I will need to get the insurance there.
