Am I Eligible for Medicare Part D?

Eligibility for Medicare Part D is not open to everyone. You must meet certain criteria to enroll in a Medicare Part D plan. Specifically, you must fall into one of the following categories:

  • You are age 65 or older
  • You have a qualifying disability for which you have been receiving Social Security Disability Insurance (SSDI) for more than 24 months1
  • You have been diagnosed with End-Stage Renal Disease (permanent kidney failure requiring a kidney transplant or dialysis)
  • You are entitled to Medicare Part A and/or enrolled in Medicare Part B

Who Should Enroll in Medicare Part D?

When you are eligible for Medicare, you are eligible for Medicare Part D. You are encouraged to enroll in a Medicare prescription drug plan when you are eligible unless you have other creditable prescription drug coverage. If you don't enroll in Medicare Part D, you will likely pay a Late Enrollment Penalty should you enroll at a later date. You should enroll in a Medicare prescription drug plan if:


  • You use prescription drugs on a regular basis
  • You think you may need prescription drugs in the future
  • You do not have creditable prescription drug coverage (as good as Medicare's)
  • You are worried about increasing prescription drug costs
  • You are having trouble paying for your prescription drugs

Medicare Part D offers assistance paying for the expenses of prescription drugs. By enrolling in a prescription drug plan, your drug costs can be lower. If you are eligible for Medicare, you should seriously consider a prescription drug plan and learn when to enroll today.
