If the person with dementia has Medicare, then he or she can enroll in Medicare's Part D prescription drug plan. Be sure to review Medicare Part D plans carefully regarding Alzheimer's drug coverage.

Part D basics

Medicare works with insurers and other private companies to offer different prescription drug plans that vary in cost and drug formularies. During the Medicare Part D annual open enrollment period, Medicare beneficiaries can enroll in a drug plan. Beneficiaries already enrolled in a Part D drug plan can change to a different plan during this period. Every year, Medicare’s open enrollment period is October 15 - December 7.


Key things to consider when choosing a drug plan:

  • Will the drug plan pay for all or most of the drugs you take now?
  • Are your Alzheimer's drugs on the formulary? 
  • Does the plan cover the doses of the drugs that you take?
  • Do the plan's rules limit coverage of your Alzheimer's drugs and/or your more costly drugs by requiring "prior approval? 
  • Do the plan's rules require you to try a less expensive, similar drug ("step therapy") before the plan will pay for your drug(s)?
  • Are there limits on the number of pills that a prescription may cover ("quantity limits") over a specific period of time?
  • What will the plan cost you? Be sure to compare all of the costs for each plan, including the deductible, copayments and co-insurance, not just the amount of the monthly premiums.
  • Is my local pharmacy in the plan's pharmacy network? If you prefer to use mail order for your drugs, does the plan offer it as an option?

Extra help paying for prescription drugs

People with Medicare who have limited income and resources may qualify for extra help paying for prescription drugs. The Social Security Administration (SSA) and CMS are working together to provide this extra assistance.
  • People with both Medicare and Medicaid (called "dual eligibles") will automatically qualify for extra help.
  • Other individuals may apply for extra help from the SSA. Apply online at www.socialsecurity.gov, or call 800.772.1213 for a paper application or to make an appointment.
