What Is Medicare Part D?
Medicare Part D helps cover the cost of prescription drugs for seniors and eligible individuals. Offered through private insurance companies, these plans work alongside Medicare Parts A and B. Each plan includes a list of covered medications, known as a formulary, with costs divided into tiers.
Access to affordable prescriptions is a big deal for seniors. Many rely on regular medications to manage chronic conditions and maintain their health. According to a 2024 AARP survey, one in five adults aged 50 and older reported spending $1,000 or more on prescription drugs in the past year.
For those on fixed incomes, this expense can be overwhelming. Medicare Part D helps lighten that load, making essential medications more affordable and accessible. As a key part of making prescription drugs attainable for those who need them most, it provides peace of mind and better health outcomes.

Notable Changes to Medicare Part D in 2025
Medicare Part D is introducing significant updates in 2025 to make prescription drug costs more predictable and manageable. According to the Medicare Rights Center, here are the key changes:
$2,000 Out-of-Pocket Spending Cap
Starting in 2025, beneficiaries will stop paying out-of-pocket costs for covered medications after reaching a $2,000 annual cap.
This means that once a beneficiary’s out-of-pocket costs — including deductibles, copayments, and coinsurance — reach $2,000, they will not incur additional costs for covered medications for the remainder of the year. In some cases, a beneficiary can meet their out of pocket cap prior to spending $2,000.
This change will provide substantial financial relief for those requiring high-cost or multiple medications.
Simplified Benefit Structure
The traditional four-phase structure of Medicare Part D is changing to improve clarity and to reduce complexity:
- Annual Deductible Phase: Beneficiaries pay 100% of their prescription costs until meeting the annual deductible, which is set at $590 for 2025.
- Initial Coverage Phase: After meeting the deductible, beneficiaries enter the initial coverage phase, where they pay 25% coinsurance for covered drugs. This phase continues until their total out-of-pocket spending reaches the $2,000 cap.
- Catastrophic Coverage Phase: Once the $2,000 out-of-pocket cap is reached, beneficiaries will have no cost-sharing responsibilities for covered Part D drugs for the rest of the year.
Notably, the coverage gap, commonly known as the “donut hole,” is being eliminated. This change simplifies the benefit structure, providing consistent cost-sharing until the out-of-pocket cap is met. These phases are the guidelines that all Medicare Part D plans have to follow. In some cases, plans might offer more coverage than what is minimally required, such as waiving the deductible, or lowering coinsurance in the Initial Coverage Phase.
Premiums and Plan Availability
The number of available Standalone Part D plans will drop, with beneficiaries now choosing from an average of 14 options in 2025 instead of 21 in 2024 in the state of Nevada.
Manufacturer Discounts
Under a new program, drug manufacturers must provide discounts — 10% during the initial coverage phase and 20% during the catastrophic phase. This helps lower the out of pocket cost that Medicare through reinsurance would have to fund for your brand name medications.
Cost-Sharing Adjustments
The standard deductible for Medicare Part D plans in 2025 is $590, an increase from previous years. However, some plans may offer lower or no deductibles, so beneficiaries should compare options carefully.
Moreover, as KFF points out, many Part D enrollees will face coinsurance rather than copayments for preferred brands and non-preferred drugs, leading to less predictable out-of-pocket costs.
Specifically, 28% of Medicare Advantage Prescription Drug plan enrollees will be in plans that charge coinsurance for preferred brands in 2025, up from 2% in 2024. For non-preferred drugs, 57% will face coinsurance, up from 11% in 2024.
How These Changes May Impact Beneficiaries
The changes to Medicare Part D in 2025 aim to make prescription drug costs more predictable, but their effects will vary depending on individual circumstances.
For current enrollees, the $2,000 out-of-pocket spending cap is a game-changer. Beneficiaries who previously faced high medication costs can now better manage their healthcare expenses. Eliminating the coverage gap also simplifies calculating costs, reducing confusion and making the program more user-friendly.
However, shifting toward coinsurance for preferred and non-preferred drugs could mean less predictable costs for some medications, and could cause greater out of pocket spending for those whose medication costs were not reaching the high out of pocket cost thresholds in 2024.
To prepare, seniors should:
- Review their plans during the annual enrollment period to see how changes will affect them.
- Explore the new Medicare Prescription Payment Plan (MPPP), which allows you to spread out-of-pocket costs over the year in manageable monthly payments.
- Check formularies to confirm that their current prescriptions are still covered and compare costs for alternative options.
Switching plans in 2025 could bring significant advantages, especially if new options offer better premiums, coverage, or pharmacy networks. Careful comparison can help beneficiaries maximize savings and access the medications they need without surprises.

Medicare Advantage and Part D: What You Need to Know for 2025
Medicare Advantage plans, also known as Part C, are all-in-one alternatives to Original Medicare. These plans often include prescription drug coverage, integrating Part D benefits into a single package. In 2025, the integration between Medicare Advantage and Part D remains essential for those seeking comprehensive coverage.
One notable change in Medicare advantage plans was a significant reduction in extra benefits, like dental and vision coverage, OTC, and hearing coverage. The changes imposed by the Inflation Reduction Act caused many plans to have to reduce out of pocket spending. Seniors should remain cautious of sales tactics plans use by focusing on extra benefits, and focus on selecting a plan that fits their healthcare needs by prioritizing provider network, prescription coverage, and out of pocket cost for medical care.
How to Choose a Medicare Part D Plan
With changes to cost structures and plan availability, beneficiaries should focus on the following:
- Drug Coverage: Check the formulary to confirm your medications are covered. Plans that categorize your prescriptions as “preferred” may save you money.
- Premiums and Deductibles: While the average premium is increasing to $45, actual costs vary. Look for plans with deductibles and premiums that match your needs.
- Pharmacy Networks: Make sure your preferred pharmacy is in-network to avoid higher costs.
Tips for finding the plan:
Consult with a trusted insurance professional if you’re unsure which plan meets your needs.
Use the Medicare Plan Finder tool to compare options side-by-side.
Review the plan’s star rating to assess quality and customer satisfaction.
