Understanding Medicare Drug Price Changes for 2026

Navigating Medicare can feel complex, especially when you hear about upcoming changes to prescription drug costs. If you’re wondering what to expect in 2026 and how it will affect your budget, you’ve come to the right place. This guide will explain the key changes and show you exactly how to check your specific medication costs.

The Big Change: Medicare Is Negotiating Drug Prices

For the first time, Medicare is able to negotiate prices directly with drug manufacturers for certain high-cost prescription drugs. This significant change is a result of the Inflation Reduction Act of 2022, a law designed to lower healthcare costs for millions of Americans.

The process is gradual, but the first negotiated prices are set to take effect on January 1, 2026. This means that if you take one of the selected drugs, you could see a noticeable drop in what you pay at the pharmacy.

Which Drugs Will Be Cheaper in 2026?

The Centers for Medicare & Medicaid Services (CMS) announced the first 10 drugs covered under Medicare Part D selected for price negotiation. These medications are widely used to treat common conditions like blood clots, diabetes, heart failure, and autoimmune diseases.

The first 10 drugs with negotiated prices taking effect in 2026 are:

• Eliquis: Used to prevent blood clots.
• Jardiance: Used to treat diabetes and heart failure.
• Xarelto: Used to prevent and treat blood clots.
• Januvia: Used to treat diabetes.
• Farxiga: Used to treat diabetes, heart failure, and chronic kidney disease.
• Entresto: Used to treat heart failure.
• Enbrel: Used to treat rheumatoid arthritis and other autoimmune conditions.
• Imbruvica: Used to treat blood cancers.
• Stelara: Used to treat psoriasis, Crohn’s disease, and ulcerative colitis.
• Fiasp; Fiasp FlexTouch; Fiasp PenFill; Novolog; Novolog FlexPen; Novolog PenFill: A group of insulin products used to treat diabetes.

It is important to remember that this is just the first list. More drugs will be selected for negotiation in the coming years, expanding the potential for savings across a wider range of treatments.

How Plan Pricing and Coverage Rules Will Be Affected

While the news of lower prices for these 10 drugs is positive, it’s crucial to understand how this impacts your specific Medicare plan. Insurance companies that offer Medicare Part D (standalone prescription drug plans) and Medicare Advantage plans (Part C) will adjust their plans in response to these new government-negotiated prices.

Here’s what that means for you:

• Changes to Formularies: A plan’s formulary is its list of covered drugs. Plans will update their formularies to reflect the new, lower prices for the negotiated drugs. This could mean a lower copay or coinsurance for you if you take one of these medications.
• Shifts in Drug Tiers: Plans often group drugs into different “tiers,” with drugs in lower tiers costing less out of pocket. A negotiated drug might be moved to a more favorable tier, reducing your cost. However, a plan might also shift other drugs to different tiers to manage its overall costs.
• Potential Premium Adjustments: While the goal is to lower costs, insurance companies may adjust their monthly premiums based on these broad market changes. It is essential to look at the total cost of a plan, not just the price of one drug.

Because every plan is different, you cannot assume your costs will automatically go down. You must actively review your plan’s details each year to ensure it still meets your needs.

A Step-by-Step Guide to Reviewing Your Prescription Costs

The most important promise of the ad was to show you how to check your costs. Here is a clear, actionable guide to help you prepare for 2026 and beyond. The best time to do your deep-dive research is during the Medicare Open Enrollment Period, which runs from October 15 to December 7 each year.

Step 1: Use the Official Medicare Plan Finder Tool

The single best resource for comparing plans is the official Medicare Plan Finder tool at Medicare.gov. It provides unbiased, personalized results based on your specific medications and pharmacy preferences.

• Gather Your Information: Before you start, make a complete list of all your prescription drugs, including the exact name, dosage, and how often you take it.
• Visit Medicare.gov: On the homepage, you can start a plan search by entering your zip code.
• Enter Your Drugs: The tool will prompt you to add your prescription drugs. Be as accurate as possible. You can create a MyMedicare account to save your drug list, which makes it much easier to compare plans each year.
• Compare Your Options: The tool will show you a list of available Part D and Medicare Advantage plans in your area. It will estimate your total annual costs for each plan, including premiums, deductibles, and drug copays. Pay close attention to this total cost estimate.
• Look Ahead: While you won’t see 2026 plan details until the fall of 2025, you can use the tool now to understand your current costs and get comfortable with the comparison process.

Step 2: Carefully Read Your Annual Notice of Change (ANOC)

If you are already enrolled in a Medicare Part D or Medicare Advantage plan, you will receive a document called the “Annual Notice of Change” or ANOC every September. This is one of the most important documents you will receive all year.

The ANOC outlines all the changes your current plan will make for the upcoming year. Look specifically for:

• Changes to the monthly premium.
• Changes to the annual deductible.
• Changes to the drug formulary. Check if any of your medications have been removed or if their tier has changed.
• Changes to your copays or coinsurance.

Step 3: Get Help from Unbiased Experts

You do not have to figure this out alone. There are free, reliable resources available to help you.

Your local State Health Insurance Assistance Program (SHIP) offers free, one-on-one counseling for Medicare beneficiaries. SHIP counselors are highly trained and are not affiliated with any insurance company, so their advice is completely impartial. They can walk you through the Plan Finder tool and help you understand your options.

Frequently Asked Questions

Will all of my prescription drugs be cheaper in 2026? No, not necessarily. The negotiated prices only apply to the specific list of 10 drugs starting in 2026. While this may create broader pricing pressure, your other medication costs will depend entirely on your specific plan’s formulary and tier structure for that year.

When can I switch plans to get these lower prices? The main opportunity to switch plans is during the annual Medicare Open Enrollment Period, which runs from October 15 to December 7. Any changes you make during this period will take effect on January 1 of the following year. To get a plan with the 2026 negotiated prices, you will need to select it during the Open Enrollment period in late 2025.

What if a medication I need is no longer covered by my plan? If your plan drops a drug you need from its formulary, you have a few options. First, talk to your doctor. There may be a similar, covered alternative you can switch to. If not, you can file for a “formulary exception” with your plan, where your doctor attests that the specific drug is medically necessary for you. This is why reviewing your ANOC each year is so critical.
