Choosing your plan
Plan type you bought or want to buy Should you buy a Part D plan?
A Medicare Advantage plan that includes Part D coverage. No. In fact, the government says you can't have both. You'll be disenrolled from your Medicare Advantage plan and left with Original Medicare and the Part D plan you bought.
A Medicare Advantage plan that doesn't include Part D coverage. No. You can't add Part D. These plans are for people who have drug coverage that's as good as Part D through another source, like a Veterans Affairs program.
A Medigap plan, also called supplement insurance. Yes. Medigap plans sold today don't include coverage for Part D prescription drugs.
