The Inflation Reduction Act and Your Medicare Prescriptions: What’s Changing in 2026

If you take Eliquis to prevent blood clots, you already know how expensive it can be. Until recently, a 30-day supply could cost Medicare beneficiaries over $500 out of pocket. But starting in 2026, the price drops to $231 — a 56% savings — thanks to the Inflation Reduction Act’s first-ever Medicare drug price negotiations.

This is a turning point for millions of seniors. For the first time in Medicare’s 60-year history, the federal government has the power to negotiate prescription drug prices directly with pharmaceutical manufacturers. Combined with a new $2,100 annual out-of-pocket cap on Part D spending, the Inflation Reduction Act represents the most significant change to Medicare prescription drug coverage since Part D was created in 2003.

Let’s break down exactly what’s changing, which drugs are affected, and how you can maximize your savings in 2026.

Medicare’s First-Ever Negotiated Drug Prices: The Basics

The Inflation Reduction Act, signed into law in August 2022, gave the Centers for Medicare & Medicaid Services (CMS) the authority to negotiate prices for certain high-cost prescription drugs. CMS selected the first 10 drugs for negotiation in 2023, and after months of discussions with pharmaceutical manufacturers, the new negotiated prices took effect on January 1, 2026.

These 10 drugs account for approximately $56.2 billion in annual Medicare Part D spending — roughly 20% of all Part D drug costs. They’re among the most commonly prescribed medications for seniors, treating conditions like diabetes, heart disease, blood clots, and autoimmune disorders.

The negotiated prices represent savings of 38% to 79% compared to what Medicare was previously paying. For individual beneficiaries, this means lower copays, lower coinsurance, and reaching the out-of-pocket cap much more slowly — or not at all.

The 10 Negotiated Medicare Drugs for 2026

Here are the 10 drugs with CMS-negotiated prices now in effect:

Combined, these negotiated prices are projected to save Medicare beneficiaries approximately $1.5 billion in out-of-pocket costs in the first year alone, while saving the Medicare program billions more overall.

Understanding Medicare’s $2,100 Out-of-Pocket Cap in 2026

Beyond negotiated drug prices, the Inflation Reduction Act introduced something Medicare Part D has never had before: a hard cap on out-of-pocket prescription drug spending. Starting in 2026, once you’ve spent $2,100 out of pocket on covered Part D drugs in a calendar year, you pay $0 for the rest of the year.

Here’s how this works in practice with Eliquis as an example:

1. You pay the $615 deductible at the start of the year (this counts toward your $2,100 cap)
2. You enter the initial coverage phase and pay 25% coinsurance on your prescriptions
3. At the negotiated price of $231/month for Eliquis, your 25% coinsurance is about $57.75 per month
4. After roughly 6–7 fills (depending on your other medications), you hit the $2,100 out-of-pocket cap
5. For the rest of the year, all your covered Part D drugs cost $0

Before the Inflation Reduction Act, there was no hard cap — beneficiaries in the catastrophic phase still owed 5% of drug costs, which could amount to thousands of dollars annually for expensive specialty medications. Now, once you reach $2,100, you’re done paying for the year.

Special Protections for Insulin Users

The Inflation Reduction Act includes specific protections for Medicare beneficiaries who use insulin, building on the $35 cap that took effect in 2023.

For NovoLog and Fiasp insulin products, the new negotiated price is $119 per month (down from $495). At 25% coinsurance, your cost would be approximately $29.75 per month — which is actually lower than the $35 cap. In this case, you’d pay the lower $29.75 amount.

Note: Insulin costs and coverage can vary by plan and pharmacy. Always verify your specific costs with your Part D plan or pharmacist before filling your prescription.

What’s Happening with Medicare Part D Premiums in 2026

One of the welcome side effects of the Inflation Reduction Act is lower Part D premiums. The national average premium for standalone Part D plans dropped from $38.31 in 2025 to $34.50 in 2026. For Medicare Advantage plans with prescription drug coverage (MA-PDs), the average Part D premium component is just $11.50 per month.

These decreases are partly due to the law’s restructuring of Part D finances, which shifts more costs to manufacturers and the government while reducing costs for beneficiaries and plans. The market is also stabilizing as insurers adjust to the new benefit structure, with some plans becoming more competitive on pricing to attract enrollees.

That said, premiums vary significantly by plan and region. A plan with the lowest premium isn’t necessarily the best value if it doesn’t cover your specific medications or preferred pharmacies. It’s important to compare Part D plans based on your total estimated annual cost, not just the monthly premium.

How to Maximize Your Prescription Savings in 2026

1. Verify Your Pharmacy Is Applying Negotiated Prices

The new negotiated prices should be applied automatically at the pharmacy counter — you don’t need to sign up for anything or request a special discount. However, it’s always smart to double-check. When you pick up a prescription for one of the 10 negotiated drugs, verify that the price reflects the new lower rate. If something looks off, ask your pharmacist to reprocess the claim.

2. Check Your Plan’s Formulary and Tiering

Even with negotiated prices, your actual cost depends on where your drug falls on your plan’s formulary tier. Plans can place drugs on different tiers (preferred, non-preferred, specialty), which affects your copay or coinsurance percentage. Review your plan’s formulary to make sure your medications are covered and placed on the most favorable tier possible.

3. Consider the Medicare Prescription Payment Plan

New in 2026, the Medicare Prescription Payment Plan lets you spread your out-of-pocket drug costs evenly across the year in monthly installments, rather than paying large amounts upfront at the pharmacy. This is especially helpful if you take expensive medications early in the year and would otherwise hit your deductible and coinsurance all at once.

4. Don’t Skip Recommended Vaccines

The Inflation Reduction Act also eliminated cost-sharing for all Part D–covered vaccines. This means vaccines for shingles, RSV, Tdap, and others that were previously covered under Part D (and could cost $200+) are now available at $0 out of pocket. If you’ve been putting off vaccinations because of cost, now is the time to get caught up.

5. Compare Plans During Open Enrollment

The best way to ensure you’re getting the lowest possible drug costs is to review your plan every year during the Annual Enrollment Period (October 15 – December 7). Plans change their formularies, pharmacies, premiums, and cost-sharing every year. What was the best plan for you last year may not be the best plan this year.

What’s Coming Next: Expansion Beyond 2026

The Inflation Reduction Act’s drug negotiation program is just getting started. CMS will continue adding drugs to the negotiation list in the coming years:

It’s worth noting that several pharmaceutical companies have filed lawsuits challenging the constitutionality of the negotiation program. As of early 2026, federal courts have largely upheld the law, but legal challenges continue. Regardless of the outcome, the 2026 negotiated prices are locked in and will not change this year.

Common Questions About the Inflation Reduction Act and Your Prescriptions

The Bottom Line: Real Savings, Right Now

The Inflation Reduction Act is delivering real, measurable savings to Medicare beneficiaries in 2026. Whether you take one of the 10 negotiated drugs or not, the $2,100 out-of-pocket cap protects every Part D enrollee from catastrophic prescription costs. And with more drugs being added to the negotiation list each year, these savings will only grow.

If you haven’t reviewed your Medicare Part D coverage recently, now is an excellent time to make sure you’re on the right plan. Drug prices, formularies, and plan structures change every year, and a plan that was perfect last year may not be the best fit today.
