Medicare Advantage Part D prescription drug coverage, often referred to as Part D, is available from private insurers to anyone who is also eligible for Original Medicare and permanently resides in the service area of a Medicare Prescription Drug Plan. Different insurers offer different types of plans, so your premium and out-of-pocket expenses for prescription drugs will vary.
Medicare Part D is prescription drug coverage. You can get Medicare Part D coverage through a stand-alone Medicare prescription drug plan or a Medicare Advantage prescription drug plan. Both are available from Medicare-approved private insurance companies.
Medicare Part D coverage is optional, but if you don’t enroll in Medicare Part D as soon as you’re eligible, you might pay a late-enrollment penalty if you enroll later.
Your monthly plan premium and out-of-pocket expenses for prescription drugs will vary from plan to plan.
