Understanding Medicare Part D in 2025:
Medicare Part D is a vital part of managing healthcare costs, offering prescription drug coverage to millions of Americans. With significant changes coming in 2025, understanding how Part D works is more important than ever. This guide breaks everything down for first-time learners, providing clear and actionable information to help you make the best decisions.
Guide to Understanding Medicare Part D
What Is Medicare Part D? and How Medicare Part D Works
Functionality
- Medicare has a standard Part D model for all insurance carriers to follow.
- Medicare provides a list of drugs that plans must cover, requiring coverage of at least two drugs in every therapeutic class.
- While CMS (the Centers for Medicare & Medicaid Services) sets these guidelines, each insurance carrier can design their coverage options differently. This means plans can vary significantly in:
- Premiums
- Copays and Coinsurance
- Deductibles
- The specific drugs they cover
Considerations
- When choosing a Part D plan, consider more than just the premium. Evaluate the deductible, cost-sharing structure (copays and coinsurance), and the drugs covered by the plan.
- With the new $2,000 out-of-pocket cap in 2025, it’s crucial to know what counts toward this limit:
- Premiums do not count toward the $2,000 cap.
- Deductibles, copays, and coinsurance for covered drugs do count.
- Often, plans with higher deductibles may offer better value for many consumers because they have lower premiums and favorable cost-sharing structures.
Two Ways to Get Medicare Part D Coverage
1. Stand-Alone Prescription Drug Plans (PDPs)
- Add prescription drug coverage to Original Medicare (Part A and Part B).
- PDPs are a great choice if you want to keep Original Medicare but need help covering prescription costs.
- Plans vary in premiums, deductibles, and the drugs they cover, so careful comparison is key.
2. Medicare Advantage Plans with Prescription Drug Coverage (MA-PDs)
- Combine your Medicare Part A, Part B, and usually Part D into one plan.
- Often include additional benefits like dental, vision, and hearing coverage.
- MA-PDs typically offer better drug coverage compared to stand-alone PDPs.
- These plans may have lower overall costs but require you to use a network of doctors and pharmacies.
Key Insight: If you want comprehensive healthcare and drug coverage, Medicare Advantage plans with Part D may be a better fit than stand-alone Part D plans.
Understanding the Phases of Medicare Part D in 2025
1. Deductible Phase
- The maximum deductible for 2025 is $590.
- Plans typically only apply the deductible to prescriptions in tiers 3, 4, and 5, which usually include brand-name and specialty drugs.
- You pay 100% of the cost for these prescriptions until you meet the deductible.
2. Initial Coverage Phase
- After meeting the deductible, you pay a copayment or coinsurance for each prescription, and your plan covers the rest.
- This phase continues until your total drug costs (what you and your plan have paid) reach a certain limit.
3. Catastrophic Coverage Phase
- Starting in 2025, there is a $2,000 out-of-pocket spending cap.
- Once you’ve spent $2,000 on covered drugs (excluding premiums), you pay nothing for the rest of the year.
Action Steps to Take
- Review Your Current Coverage: Check your plan’s premium, deductible, copays, and drug coverage to ensure it still meets your needs.
- Compare Available Plans: Use the Medicare Plan Finder tool to see how stand-alone Part D plans and Medicare Advantage plans with drug coverage compare.
- Understand Enrollment Rules: Once you enroll in a stand-alone Part D plan, you can only change plans during the Annual Enrollment Period (Oct. 15 – Dec. 7) or if you qualify for a Special Enrollment Period (e.g., moving or losing other coverage).
- Seek Expert Help: If you’re unsure about your options, contact a licensed Medicare advisor for guidance.

This phase is called catastrophic coverage phase and in this phase prescription cost comes down to around 5% of the retail cost. This phase lasts until the end of the calendar year.
Fortunately most people on Medicare never leave phase two, for those that do it can be quite expensive.
If you want to stay out of the coverage gap it is always a good idea to speak with your doctors about taking generic options when possible. Many drug manufacturers also offer prescription assistance for many of their expensive drugs and there are a few states that have off state pharmaceutical assistance programs that can help with costs.
When enrolling in Medicare Part D, the prescription drug coverage component of Medicare, there are several key points to consider to ensure you choose the most suitable plan for your healthcare needs and budget. Here’s what you need to know:
1. Eligibility and Enrollment Periods: You are eligible to enroll in a Medicare Part D plan if you are already enrolled in Medicare Part A and/or Part B. You can enroll in a Part D plan during the Initial Enrollment Period (IEP) when you first become eligible for Medicare. Additionally, there’s the Annual Enrollment Period (AEP), which typically runs from October 15 to December 7 each year, during which you can review and change your Part D plan.
2. **Types of Part D Plans:** Part D plans are offered by private insurance companies approved by Medicare. There are standalone Part D plans that work alongside Original Medicare (Parts A and B), and there are also Medicare Advantage plans that include Part D prescription drug coverage (MA-PD plans).
3. **Formulary and Drug Coverage:** Each Part D plan has a formulary, which is a list of covered prescription drugs. Formularies can vary significantly between plans, so it’s essential to check whether your specific medications are included and at what cost. Make sure your essential medications are covered and that there are no significant restrictions.
4. **Pharmacy Network:** Part D plans may have preferred pharmacy networks where you can get your medications at lower costs. Verify that your preferred pharmacy is in the plan’s network to ensure you can access your medications conveniently.
5. **Premiums, Deductibles, and Copayments:** Part D plans come with premiums, deductibles, and copayments or coinsurance. Compare the costs of different plans to understand your out-of-pocket expenses for premiums and medications.
6. **Coverage Gap (Donut Hole):** Part D plans have a coverage gap, also known as the “donut hole.” This means that after reaching a certain spending limit on medications, you’ll be responsible for a higher portion of the drug costs until you reach the catastrophic coverage threshold. Take this into account when evaluating the overall cost of a plan.
7. **Late Enrollment Penalty:** If you don’t enroll in a Part D plan when you are first eligible and don’t have other creditable prescription drug coverage (e.g., from an employer or union), you may face a late enrollment penalty if you decide to enroll later. The penalty is added to your premium and can last as long as you have Part D coverage.
8. **Medication Changes:** Formularies can change annually, so it’s a good idea to review your plan’s Annual Notice of Change (ANOC) each fall to see if there are any changes that may affect your coverage or costs for the upcoming year.
9. **Plan Ratings and Reviews:** Medicare provides star ratings for Part D plans based on their quality and performance. Consider looking into these ratings and read reviews of different plans to get an idea of how well they serve their beneficiaries.
10. **Medicare.gov Resources:** The official Medicare website (medicare.gov) is an excellent resource for comparing Part D plans in your area, understanding costs, and finding helpful information on prescription drug coverage.

Medicare Part D Page Q & A
No original Medicare Part A & B do not cover daily prescriptions that you get at the pharmacy. Original Medicare will cover your medications taken while in the hospital, some vaccinations and infusions but not your daily medications.
Currently in NY state there are 19 plans offered ranging between $10.90- $116.80
Part D plans follow a formulary model from CMS (Center of Medicare & Medicaid Services) No plan will cover all drugs but each plan has to cover the minimum of two drugs in each therapeutic category. So you should be able to find a drug plan that covers the prescription you need. If you no one covers the necessary drugs you can file an appeal to have it covered by your plan.
Many Part D plans will have a deductible in 2023 they can be as high as $505.00, but ot all plans have a deductible and many popular prescriptions can be purchased without having to meet a plan deductible.
If this happens you can do a few things, ask your doctor for a substitute that is covered. You can request a formulary exception. If they deny your exception you can file an appeal. Lastly you can change your plan if you have an enrollment period to do so.
The Medicare Part D penalty occurs when someone who could have enrolled in Medicare Part D coverage but chooses not to enroll in a plan later. Those who enroll late will be assessed a life time penalty of 1% of the cost of the national average for a Part D drug plan for each month they were not enrolled.
Drug tiers are simply the way that a Part D plan decides to classify their prescriptions. It is fairly typical for plans to have up to 5 tiers. Most plans Tier 1= preferred generic drugs tier 2 = non preferred generic drugs tier 3 = preferred brand names tier 4 non preferred brand name drugs and tier 5 = specialty drugs.
NO most likely most Part D plans do not cover vitamins. The only one I see covered regularly if Vitamin D.
