What does Medicare Part D cover?
Part D (prescription drugs coverage). Medicare Part D is an outpatient prescription drug coverage. To get drug coverage you must join a Medicare-approved plan, such as a Medicare Advantage plan with drug coverage or a standalone Medicare Prescription Drug plan.
Do I need to enroll in Part D?
If you do not enroll in a Part D plan when you are first eligible and do not have other creditable prescription drug coverage (coverage that is at least as good as Medicare’s standard coverage), you may have to pay a late enrollment penalty if you enroll in a Part D plan later on.
