Are you unsure of your Medicare Part D eligibility, or confused about what it covers and how much it can save you on prescription medicine? If so, you are not alone. Because Medicare’s structure is so different from private insurance, it can be challenging to navigate your options. 


Our team at Meadowcrest Family Physicians is here to help. With our extensive experience in helping patients navigate their healthcare options and 25+ years of providing care to Medicare recipients, we have the know-how to guide you through this process. In this blog, we will walk you through eligibility requirements, open enrollment periods, and rest-of-year enrollment options for those who qualify. Let’s dive in!

Who is Eligible for Medicare Part D Coverage?

Medicare Part D, also known as the Prescription Drug Plan, ensures access to affordable prescription medications for those who need it most. A vital part of the Medicare healthcare landscape, it helps cover the cost of prescription medications and offers significant relief to those who require regular or specialized medication. These plans are offered by private insurance companies but are regulated by the Medicare program. Consider the following criteria to help determine your eligibility for Medicare Part D: 

  • Individuals aged 65 or older who are entitled to or already enrolled in Medicare are eligible for Part D drug insurance
  • You must be already enrolled in Medicare Part A and/or Part B to receive Part D benefits
  • Eligibility extends to individuals who have received Social Security disability payments for at least two years.

How to Get Medicare Part D Prescription Drug Coverage

Once you have confirmed your Medicare Part D eligibility, the next step is to join a Medicare drug plan. This might be through a traditional Part D stand alone prescription drug plan, or it could be part of a Medicare Advantage Plan (Part C) that includes drug coverage. Because Medicare Advantage plans typically include comprehensive, all-in-one coverage, we recommend Medicare Advantage plans to get the best, most affordable benefits.

While enrollment is voluntary, you should know that there could be a late enrollment penalty if you don’t join a Medicare drug plan when you’re first eligible, unless you have other creditable prescription drug coverage. This penalty kicks in if you go at least 63 days without sufficient prescription drug coverage after your initial Medicare enrollment period ends. 

So, after the initial enrollment period, what other times can you join or switch to a Medicare Part D plan? Open enrollment for Medicare Part D occurs annually from October 15 to December 7. This is the period during which all people with traditional Medicare can make changes to their existing plans or switch to a Medicare Advantage Plan. 

If you already have a Medicare Advantage plan, then your Open Enrollment Period runs from January 1 to March 31 each year. During this time, you can switch to another Medicare Advantage plan, or drop your Medicare Advantage plan and return to Original Medicare. If you switch to Original Medicare during this period, you’ll have until March 31 to also join a Medicare Prescription Drug Plan.

Rest of Year Enrollment for Medicare Part D

It’s important to note that in most cases, changes to your Medicare Part D prescription drug coverage outside of the Open Enrollment periods listed above can only be made under certain special circumstances, such as if you move out of the plan’s service area, lose other creditable prescription drug coverage, or qualify for a Special Needs Plan (SNP). 

If you are eligible for a SNP, then you can make changes to your Medicare benefits, including your prescription drug coverage, at any time of the year. 

SNPs are specifically designed to provide targeted care for certain groups of people that fall into three distinct categories:

  • Chronic Condition Special Needs Plans (C-SNPs): C-SNPs are designed for beneficiaries with severe or disabling chronic conditions. These conditions may include diabetes, heart failure, chronic lung disorders, or others. The goal of these plans is to provide coordinated healthcare services to individuals who require specialized expertise, provider networks, and drug formularies tailored to their specific conditions.

  • Dual Eligible Special Needs Plans (D-SNPs): D-SNPs cater to individuals who qualify for both Medicare and Medicaid and aim to coordinate the array of benefits these individuals receive from both programs into one plan. This can make managing healthcare services easier for beneficiaries, potentially reducing their overall healthcare costs.

  • Institutional Special Needs Plans (I-SNPs): I-SNPs provide coverage for individuals who live in institutions, such as nursing homes, or those who require nursing care at home. The care provided offers a comprehensive, targeted healthcare program, which includes routine check-ups, preventive care, and coordination of services between healthcare providers.

Remember, after determining your Medicare Part D eligibility, you will also need to carefully consider your current and anticipated prescription drug needs in order to choose the best plan. Always review any plan’s formulary, or list of covered drugs, to ensure your medications are covered, and be sure to check out your FAQ about Medicare Part D here.
