Medicare Prescription Drug Plans (PDPs) are also known as Medicare Part D. Medicare Part D is a government program that offers prescription drug insurance to everyone who is entitled to Medicare Part A and/or enrolled in Medicare Part B.

When you are ready to decide on a plan, take the time to understand how the plans work. That way, you can make an informed decision and choose the plan that's right for you.

Different PDPs Cover Different Drugs

The federal government has specific guidelines for the types of medications we must cover as well as a minimum standard of benefits we must follow.

Each plan has a formulary (a list of covered drugs) that meets these requirements as required by law. Keep in mind, not all plans are the same. They may vary in cost or specific drugs covered.

If you enroll in a Medicare Part D plan, please review the plan's formulary to ensure it will meet your prescription drug coverage needs.

If You Have a Current Medicare Advantage Plan

If your Medicare Advantage Plan includes prescription drug coverage and you join a Medicare PDP, you will be disenrolled from your Medicare Advantage Plan and returned to Original Medicare with your Medicare PDP.

Late Enrollment Penalty (LEP)

If you decide not to join a Medicare PDP when you are first eligible, and you don't have other creditable prescription drug coverage (at least as good as Medicare's), for 63 days or more, or you do not get Extra Help, you will likely pay a late enrollment penalty. The Late Enrollment Penalty (LEP) amount will be added to your premium and sent to Medicare.

When It Comes to Coverage, You Have Options:

  • You can get Medicare prescription drug coverage through a Medicare PDP (Part D).
  • You can sign up for a Medicare Advantage plan (HMO or PPO) or other Medicare health plan that offers Medicare prescription drug coverage.
