If you’ve been on Medicare, you know that prescription drug coverage can be complex. However, starting in 2025, Part D underwent its most significant update in years, and for 2026, those benefits continue with important inflation adjustments.
As we approach the Open Enrollment Period for 2026 (from October 15 to December 7, 2025), it’s the perfect time to understand how the plan structure protects you. The confusing “donut hole” is gone, replaced by a much simpler system with a firm cap on what you’ll spend each year.
This guide provides an accurate, up-to-date overview of what you can expect from your Part D coverage in 2026.
What is Medicare Part D?
Medicare Part D remains the part of Medicare that helps cover the cost of your prescription drugs. Offered by private insurers approved by Medicare, these plans are essential for managing medication expenses. While the purpose of Part D hasn’t changed, the way it works is now more straightforward and financially protective.
The Biggest Change: A $2,100 Cap and No More “Donut Hole”
This is the most important update to understand: The coverage gap, or “donut hole,” is eliminated.
It has been replaced by a simpler system with two key features for 2026:
- A ~$2,100 Annual Out-of-Pocket Cap: For the 2026 plan year, there is a ceiling on what you will spend on covered prescription drugs. Once your out-of-pocket costs reach this annual limit (projected to be around $2,100), you will pay $0 for your covered drugs for the rest of the year. This provides an incredible level of financial security.
- The Medicare Prescription Payment Plan: Many plans will offer the new program that allows you to pay your out-of-pocket costs in monthly installments, rather than facing high costs all at once. This helps make medication expenses more predictable.
This new design removes the old, complicated phases and gives you a clear, understandable limit on your annual drug spending.
Key Enrollment Periods for Your 2026 Coverage
Enrolling at the right time is still crucial.
Initial Enrollment Period (IEP): For those new to Medicare, this is your first and best opportunity to enroll. It’s the seven-month window around your 65th birthday (three months before, your birthday month, and three months after). Enrolling during your IEP ensures you avoid any potential late enrollment penalties.
Open Enrollment Period (October 15 – December 7, 2025): This is the annual window for all beneficiaries to review their coverage. Given the plan improvements, this year is a particularly important time to compare your options and ensure your plan works for you under the new structure.
How to Choose the Right Plan in This New Landscape
While the out-of-pocket cap applies to all plans, there are still important differences between them. When specific 2026 plan details become available, here’s what to focus on:
- Formulary (Drug List): Ensure the medications you need are on the plan’s list of covered drugs.
- Monthly Premiums and Deductibles: These costs will still vary between plans.
- Pharmacy Network: Check that your preferred pharmacy is in the plan’s network to ensure you get the best pricing.
- Participation in the Payment Plan: If spreading out your costs is important to you, look for plans that offer the new Medicare Prescription Payment Plan.

Frequently Asked Questions
With the new out-of-pocket cap, does it still matter which plan I choose? Yes, absolutely. While the cap protects you from catastrophic costs, your monthly premiums, annual deductible, and copayments until you reach the cap will vary significantly between plans. Choosing the right plan is still the best way to save money.
What if I need help affording my premiums and other costs? The Extra Help program is still available to help qualifying individuals with their Part D premiums, deductibles, and copayments.
Can I have both a Medicare Advantage plan and a Part D plan? Typically, no. Most Medicare Advantage (Part C) plans already include prescription drug coverage. If your plan includes this benefit, you cannot enroll in a separate Part D plan.
