Q. Should I enroll in Part D?
The Short Answer
Part D plans are plans from insurance companies which cover prescription drug expenses. If you purchase a Medicare supplement insurance plan, you will need to purchase a Part D plan separately. However, if you enroll in a Medicare Advantage plan, Part D coverage may already be included.
It is important to always either have creditable coverage or a Part D plan once you turn 65. If you are covered under an employer or spouse's/partner's employer plan, you will be notified if what you have is creditable coverage. If you will not have creditable coverage upon turning 65, you should enroll in a Part D plan. Skipping Part D enrollment means you will need to pay a monthly penalty if you ever do decide to enroll in Part D, as long as you have Part D.
