How to Enroll

Medicare Part D is a collection of prescription drug coverage plans. Finding the plan that best matches your needs is simple, as is enrolling.

Whether you currently are enrolled in Medicare Part D, or you would like to find out more, you can speak with a Medicare counselor by calling 1-800-MEDICARE (1-800-633-4227).

Counselors can provide you with information about the Part D prescription drug benefit and answer your questions.

To prepare for a discussion with a counselor, you should have the following information ready:

  • A list of the prescription drugs you take, including the dosage and frequency
  • Your Medicare ID card
  • The name and phone number of your preferred pharmacy


You are also able enroll online through the Plan Finder.

Four Steps for Joining the Best Medicare Prescription Plan for You.

1. Determine Your Eligibility

Anyone eligible for Medicare Part A (whether actually enrolled or not) or anyone who is currently enrolled in Medicare Part B may join Medicare Part D to get help paying for prescription drugs.

Enrollment is voluntary -- except for people who also receive benefits from Medicaid. If you qualify for Medicaid, the government automatically enrolls you in a Medicare Part D plan through which you will receive your prescription drug coverage.

To learn more visit the Medicare Today Eligibility Summary section.

If you are currently enrolled in another prescription drug coverage plan (through an employer or privately, etc.), you may still qualify for Medicare Part D.

Visit the My Medicare Matters Web site to learn more about your eligibility to learn more about how your current plan affects your eligibility.

To determine if you are eligible for Medicare coverage, you can visit the Medicare Eligibility Tool. If you have questions about your eligibility for Medicare Part A or Part B, or if you want to apply for Medicare, please call Social Security at 1-800-772-1213 or visit or call your local Social Security office. TTY users should call 1-800-325-0778.

You can also get information about buying Part A as well as Part B if you don't qualify for premium-free Part A.

2. Make Sure That Your Medicines are Covered by the Plan You Choose

Medicare Part D has many different drug plans and each may have a different "formulary," or list of drugs that are covered. It is important you ensure that the drugs you take are in the formulary of the plan you select.

As you are choosing plans, be aware that some plans may require prior authorization. Plans that require prior authorization require verification from your doctor that there is a medical reason why you must use a particular drug. These plans require that verification before they will cover certain prescriptions.

It is also important to check the different costs you will be expected to pay for the drugs covered, as the amount you pay for your drugs may be different from plan to plan. To lower costs many plans place drugs into different "tiers" that cost different amounts. Each plan may structure its tiers in different ways.
