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)

The late enrollment penalty is an amount added to your monthly Medicare drug plan (Part D) premium for as long as you have Medicare prescription drug coverage.  You may owe a late enrollment penalty if you didn’t join a Medicare drug plan when you were first eligible for Medicare Part A and/or Part B, and:
  • You didn’t have other prescription drug coverage that met Medicare’s minimum standards; OR
  • You had a break in coverage of at least 63 days

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.
