Medicare Open Enrollment runs from October 15 through December 7, 2025. Significant changes take effect January 1, 2026, impacting what you’ll pay and the benefits you’ll receive. Medicare Part B premiums are jumping by double digits while Medicare Part D brings both increases and valuable new benefits. Whether you’re in Original Medicare or Medicare Advantage, understanding these changes now helps you choose the right coverage for next year. Keep reading to discover how these changes will affect you.
Part B Premiums Rise Sharply
You’ll pay considerably more for Medicare Part B in 2026. The standard monthly premium is projected to increase 11.6% to $206.50, up $21.50 from this year’s $185. This represents the largest dollar increase since 2022 and nearly double the growth rate from 2024 to 2025. Your annual deductible is also climbing 12% to $288, a $31 jump from the current $257.
These increases hit at a challenging time. While Social Security benefits are expected to rise by about 2.7% in 2026 (roughly $54 per month for the average retiree), that gain gets partially offset by higher Part B premiums automatically deducted from your check. The hold-harmless rule protects some beneficiaries from paying the full increase, but most Medicare enrollees will feel the impact. Higher-income beneficiaries face additional surcharges through the Income-Related Monthly Adjustment Amount (IRMAA), which bases your 2026 charges on your 2024 tax return.
The rising costs stem from increased healthcare utilization, medical inflation, and legislative changes affecting how Medicare covers services. Part B covers physician services, outpatient care, durable medical equipment, and certain preventive services. With medical expenses continuing to climb and new treatments entering the market, Medicare’s costs have grown substantially.
Part D Costs and Payment Options
Your out-of-pocket maximum for prescription drugs is increasing to $2,100 in 2026, up from $2,000 this year. Once you reach this threshold, you won’t pay anything more for covered medications for the rest of the year. The standard deductible is also rising to $615 from $590. These increases reflect inflation adjustments built into the Inflation Reduction Act’s restructuring of Medicare Part D benefits.
However, the Medicare Prescription Payment Plan offers a way to manage these costs. This voluntary program, which launched in 2025, now includes automatic renewal for 2026. It lets you spread your drug costs in equal monthly payments throughout the year instead of paying everything upfront at the pharmacy. The program doesn’t reduce your total costs, but it makes budgeting more predictable. It’s particularly helpful if you have expensive medications early in the year when you’re working through your deductible and initial coverage phase.
Drug Prices Drop Through Negotiations
Insulin coverage gets even better in 2026. Your monthly cost for covered insulin products will be the lesser of $35 or 25% of the negotiated price established through Medicare’s Drug Price Negotiation Program. No deductible applies to insulin, and this cap continues indefinitely. Adult vaccines recommended by the Advisory Committee on Immunization Practices remain free with no cost-sharing. This includes shingles, flu, COVID-19, and other recommended vaccines.
For the first time, Medicare’s negotiated drug prices take effect January 1, 2026. The program selected 10 high-cost medications for initial negotiations, and these lower prices are expected to save enrollees $1.5 billion in 2026 alone. These drugs must be included on all Part D and Medicare Advantage plan formularies. A second round of negotiations covering 15 additional drugs will result in lower prices starting in 2027.
Behind the scenes, structural changes are working in your favor. The Manufacturer Discount Program replaced the old Coverage Gap Discount Program, requiring drug manufacturers to provide discounts during both the initial coverage and catastrophic coverage phases. Manufacturers must also pay rebates to the federal government when their drug prices rise faster than inflation. These changes shift more cost burden from you and Medicare to pharmaceutical companies. The result shows in the numbers as average Part D premiums drop to $34.50 per month in 2026, down from $38.31 this year.
Medicare Advantage Shows Stability
If you’re in a Medicare Advantage plan, you’ll see lower average premiums in 2026. Plans with integrated prescription drug coverage will average $11.50 per month, down from $13.32 this year. Many plans continue offering $0 premiums beyond what you already pay for Part B. Your maximum out-of-pocket limit for medical services (not including prescription drugs) is decreasing slightly to $9,250 from $9,350 in 2025.
The Medicare Advantage marketplace remains largely stable, though some insurers are reducing their service areas or exiting certain regions. There are 5,600 Medicare Advantage plans available nationally in 2026, down slightly from 5,633 this year. If your plan is being discontinued, you have guaranteed-issue rights to enroll in most available Medigap plans if you switch to Original Medicare. Benefits like hearing, dental, and vision coverage are expected to remain stable, though supplemental benefits specifically for chronically ill enrollees may see some changes.
Review Your Coverage Options Now
You can make several types of changes during open enrollment. Switch between Original Medicare and Medicare Advantage, change from one Medicare Advantage plan to another, or add, drop, or switch Part D prescription drug coverage. If you’re currently enrolled in Medicare Parts A and B but don’t have additional coverage, you can join a plan for the first time.
Start by reviewing your Annual Notice of Change, which arrives by October 1 from your current plan. This document details every change to your premiums, covered drugs, costs, and provider networks for 2026. Don’t assume your current plan still works best for you. Plans can change dramatically year to year, and what suited you in 2025 might not be ideal for 2026. Your medications might move to different tiers with higher copays, your doctors could leave the network, or your premiums might increase significantly while other plans offer better value.
Consider whether the Medicare Prescription Payment Plan makes sense for your situation. If you take expensive medications, especially early in the year, spreading costs over 12 monthly payments can ease your budget. The program automatically renews in 2026 unless you opt out. Remember that your 2026 IRMAA surcharges are based on your 2024 tax return, so review whether income-related adjustments will affect your premiums.
Medicare Open Enrollment ends December 7, 2025. Any changes you make become effective January 1, 2026. If you’re currently in a Medicare Advantage plan, you’ll have another opportunity to switch plans or return to Original Medicare during the Medicare Advantage Open Enrollment Period from January 1 through March 31, 2026, but this later period offers fewer options than the fall enrollment window.
Conclusion
The 2026 changes to Medicare represent a mix of challenges and opportunities. While Part B premiums are rising sharply, Part D improvements including negotiated drug prices, lower average premiums, and enhanced payment options provide real value for beneficiaries. The key is reviewing your options during open Medicare Open Enrollment rather than automatically renewing your current coverage. Even small differences in plan features can add up to significant savings over the course of a year.
Don’t let the complexity stop you from finding better coverage. Licensed agents provide free assistance comparing plans, explaining benefits, and handling enrollment paperwork. With significant changes coming to both costs and benefits, taking time now to speak with a licensed agent can potentially save you hundreds or even thousands of dollars next year.
