Prescription Drug Plans

Medicare Part D, the prescription drug benefit, is the part of Medicare that covers most outpatient prescription drugs. Part D is offered through private companies either as a stand-alone plan (for those enrolled in Original Medicare) or as a set of benefits included with your Medicare Advantage Plan.Unless you have creditable drug coverage and have a Special Enrollment Period, you should enroll in Part D when you first get Medicare. If you delay enrollment, you may face gaps in coverage and enrollment penalties.Each Part D Plan has a list of covered drugs, called its formulary. If your drug is not on the formulary, you may have to request an exception, pay out of pocket, or file an appeal.A drug category is a group of drugs that treat the same symptoms or have similar effects on the body. All Part D Plans must include at least two drugs from most categories and must cover all drugs available in the following categories:
  • HIV/AIDS treatments
  • Antidepressants
  • Antipsychotic medications
  • Anticonvulsive treatments for seizure disorders
  • Immunosuppressant drugs
  • Anticancer drugs (unless covered by Part B)
  • Part D plans must also cover most vaccines, except for vaccines covered by Part B.
Part D Plans must also cover most vaccines, except for vaccines covered by Part B.
Some drugs are explicitly excluded from Medicare coverage by law, including drugs used to treat weight loss or gain, and over-the-counter drugs.


Things to consider:

  • In 2026, Part D will undergo significant changes due to the Inflation Reduction Act. These changes aim to make prescription drugs more affordable for Medicare enrollees. Key updates include:

    • $2,100 out-of-pocket cap: Beneficiaries will no longer have to spend more than $2,100 per year on prescription drugs.

    • Elimination of the coverage gap ("donut hole"): This will reduce costs during the middle phase of drug spending.

    • Insulin cost cap: Insulin prices will be capped at $35 per month.

    • Expanded vaccine coverage: All recommended vaccines will be free for beneficiaries.

  • If you do not join a Medicare drug plan when first eligible and you don’t have other creditable prescription drug coverage (such as a creditable employer-sponsored plan) you may have to pay a late penalty once you do join.

  • There is a premium for each plan offered. While these premiums may be in some cases quite low, it is important to focus on the TOTAL ANNUAL ESTIMATED COSTS of your medications under each plan. Part D plans not only have a premium, they also can come with deductibles as well as YOUR out-of-pocket costs for the medications you are taking.

  • On top of your Part B premium you may be subject to paying an additional IRMAA fee. The IRMAA fee is directly related to your income (2 years prior).  This can be a confusing step and we take time with our clients to review these costs one on one.

  • Your costs of each drug depend on the carrier and their corresponding plan. Medications under each plan are put into Tiers. The higher the tier, the higher price you will pay for your drugs. Not all drugs for each plan will be in the same Tier which means it is extremely important to pay close attention to how each plan breaks down your list of medications. This is an extremely personal step in determining your drug coverage. We stress the importance of this step with our clients – walking them through these costs so there are no surprises.

  • Plan costs change every year – it is important to review your Part D Prescription Drug plan each year during the Annual Election Period/ Open Enrollment (Oct 15th – December 7th) – we review this with our current clients!
