What is Medicare Part D?

Medicare is made up of parts that each cover a different type of medical need. Medicare Part D is specifically designed to help cover prescription drug costs. You can add a Part D plan to your Medicare coverage if you are eligible for Medicare Part A and Part B. Or, you may choose to enroll in a Medicare Advantage plan that likely includes prescription drug coverage (MAPD).

Coverage for prescription drugs is not included in Medicare Supplement insurance plans sold after 2006.

Medicare is made up of Part A (hospital insurance) and Part B (medical insurance) and does not cover prescription drug costs. Part D plans are offered by private insurance companies. They have an additional monthly premium that you must pay for this optional benefit.

You are not required to have a Medicare prescription drug plan. However, it may be a good idea to enroll in a plan at the same time you choose your Medicare coverage. If you wait, you may have to pay a late penalty for adding Part D later.

With the cost of prescription medications rising faster than the average paycheck,1 it’s important to think about options that can help. Take time to understand the parts of Medicare so that you can decide the best Medicare options for your needs.
