Medicare Part D Prescription Drug Plans

Part D  is one of the four parts of Medicare. It covers prescription drugs, which Original Medicare doesn’t cover. Part D can help you save on prescription costs.

Medicare Part D Coverage


Original Medicare (Part A and Part B) does not include prescription drug coverage (Medicare Part D). That’s why a Part D plan is a good idea if you have prescriptions to fill regularly or just want help covering medication costs.


You can get a prescription drug plan from Amerigroup once you’ve enrolled in Original Medicare. Here are some benefits you’ll find with our stand-alone prescription drug plans:


 A network of more than 66,000 pharmacies – almost every pharmacy in America.


 24,000 preferred pharmacies we work with to help you save on many prescription drugs.


 Competitive monthly premiums.


 Copayments as low as $0 to $5.

Medicare Part D Eligibility


You’re eligible for a prescription drug plan after you’ve enrolled in Original Medicare. The first enrollment period for Part D is the Initial Enrollment Period (IEP). That’s a seven-month window that includes:


 Three months before you turn 65


 The month you turn 65


 Three months after you turn 65


During this time, you can apply for Part D coverage along with Medicare Part A and Part B. Even if you are not taking prescription medications, it’s best to enroll in Part D as soon as you’re eligible to avoid penalties. You can still add Part D coverage after your Initial Enrollment Period. You can also make changes to your plan, including adding coverage, during the Annual Enrollment Period from October 15 to December 7 each year.

Medicare Part D Costs

Shop Plans

Plan Premium

Medicare Part D costs differ by plan and location. Most plans require a monthly premium, which you pay in addition to any premiums you may owe for Medicare Part A or Part B.


If you are enrolled in a Medicare Advantage plan (Part C) that includes prescription drug coverage, your plan premium may include the cost for your Medicare Part D coverage.

Other Costs

In addition to your monthly plan premium, other Medicare Part D costs may include a yearly deductible and copayments.

Medicare Part D Penalty


If you don’t enroll in Medicare Part D when you are first eligible, and you go without creditable prescription drug coverage for 63 days in a row or more, you could face a late-enrollment penalty if you decide to sign up for Part D later. This penalty is an extra cost that is added to your monthly Medicare Part D premium, and you may have to pay this higher premium permanently.


Because of this penalty, many people choose to sign up for Medicare Part D when they are first eligible, even if they are not currently taking prescription medications.

Prescription Drug Coverage Options


It’s important to keep in mind that a stand-alone Part D plan is not your only option for prescription drug coverage. Most of Amerigroup’s Medicare Advantage (Part C) plans are all-in-one plans that cover prescription drugs, along with other benefits like dental and vision insurance.


If you have a Medicare Advantage plan that includes prescription drug coverage, you don’t need a stand-alone Part D prescription drug plan.

Set Up Your Member Account
