I want to strongly support Community Admin Lori Foster's suggestion that you look into the free Medicare counseling that's available thru your State Health Insurance Assistance Program (every state has a SHIP). SHIP offers expert unbiased Medicare counseling thru local area agencies on aging or other community-based partners. SHIP counselors are highly-trained volunteers who will help you to understand the pros and cons of each option available to you. They can also alert you to issues related to the times of the year when you can or can't make a switch and how to avoid any penalties (e.g., if you go back to original Medicare, you need to choose a Part D prescription plan within 63 days; also, you have 60 days where you can choose a supplement or Medi-gap plan if you want and can afford one). Hope this helps.
