*The number of formularies counts the unique formularies that offer this medication. As a note, the same formulary can be used by one or many different Medicare Part D plans. The same formulary can be used by both PDP and MAPD plans.

What Could the Addition of New Generic Drugs Mean to You?

  • You may be able to save money by switching from the brand-name drug to its generic equivalent – with your prescriber’s approval and a new prescription. Please note, you will need to look carefully at coverage costs as we have found that many generics are being offered on the same tier as their brand-name equivalent or the generics do not have a significantly lower retail price.

  • Your brand-name drug may no longer be available if a generic is now available. Based on past experience, you may find that many Medicare Part D plans discontinue coverage for the brand-name drug in the months following the introduction of the generic equivalent - or your plan may immediately drop the brand-name drug now that the generic is being introduced.

    If you have received notice from your Medicare Part D plan that your brand-name medication will be dropped, you should speak with your prescriber to determine if you can take the generic equivalent or if you must continue taking the brand-name drug, you will need to ask your plan for a formulary exception to continue coverage for your brand-name drug.

    You can click for a chart showing the trends in formulary coverage for some of the more popular Medicare drugs and their generic equivalents.
As a note, both our Formulary Browser (you can view all the drugs covered by a single Medicare prescription drug plan) and our Q1Rx Drug Finder (you can view all the Medicare drug plans covering a single drug) have been updated with the May 2024 Medicare Part D formulary data.

  • Medicare evaluates plans based on a 5-Star rating system. Star Ratings are calculated each year and may change from one year to the next.
  • A Medicare Advantage Private Fee-for-Service plan (PFFS) is not a Medicare supplement plan. Providers who do not contract with the plan are not required to see you except in an emergency.
  • Disclaimer for Institutional Special Needs Plan (SNP): This plan is available to anyone with Medicare who meets the Skilled Nursing Facility (SNF) level of care and resides in a nursing home.
  • Disclaimer for Dual Eligible (Medicare/Medicaid) Special Needs Plan (SNP): This plan is available to anyone who has both Medical Assistance from the State and Medicare.

  • Medicare MSA Plans combine a high deductible Medicare Advantage Plan and a trust or custodial savings account (as defined and/or approved by the IRS). The plan deposits money from Medicare into the account. You can use this money to pay for your health care costs, but only Medicare-covered expenses count toward your deductible. The amount deposited is usually less than your deductible amount, so you generally have to pay out-of-pocket before your coverage begins.
  • Medicare MSA Plans do not cover prescription drugs. If you join a Medicare MSA Plan, you can also join any separate (stand-alone) Medicare Part D prescription drug plan
  • There are additional restrictions to join an MSA plan, and enrollment is generally for a full calendar year unless you meet certain exceptions. Those who disenroll during the calendar year will owe a portion of the account deposit back to the plan. Contact the plan provider for additional information.
