How to Reduce Medicare Part D Costs in 2026

Your Part D Drug Costs Can Drop Significantly in 2026

If you're looking for ways to reduce Medicare Part D costs in 2026, several concrete strategies can make a real difference at the pharmacy counter. The most important protection already in place is the $2,000 annual out-of-pocket cap on covered drug costs, once you reach that limit, you pay nothing for covered prescriptions for the rest of the year. And starting January 1, 2026, Medicare-negotiated prices on ten widely used drugs take effect for the first time under the Inflation Reduction Act, automatically lowering costs for millions of people without any extra steps required.

Beyond those automatic changes, you can take direct action: applying for Extra Help, switching to a lower-cost plan, requesting generics, and using mail-order can together save hundreds to thousands of dollars a year. To understand where Part D fits into your total Medicare spending, see our guide on how much does medicare cost across all program parts. Then use the steps below to target your prescription drug costs specifically.

Apply for Extra Help First

The medicare extra help program, formally called the Low Income Subsidy (LIS), is the single most powerful tool available to cut Part D costs. Depending on your income and assets, it can eliminate your Part D deductible entirely, cap your monthly plan premium, and bring drug copays down to just a few dollars per prescription.

For 2026, you may qualify if your income is at or below roughly 150 percent of the federal poverty level. The Social Security Administration (SSA) sets and publishes the exact income and asset limits each year, so always check SSA.gov for the most current 2026 figures. The application is free and takes about 15 minutes online at SSA.gov or by phone at 1-800-772-1213.

If you already receive Medicaid, Supplemental Security Income (SSI), or qualify for a medicare savings programs, you are automatically enrolled in Extra Help, no separate application is needed. Medicare Savings Programs (MSPs) are state-run programs that help cover Medicare premiums and cost-sharing; qualifying for any MSP triggers automatic Extra Help enrollment for Part D.

• Full Extra Help, covers your plan premium up to the regional benchmark, eliminates the deductible, and limits copays to a few dollars per drug
• Partial Extra Help, reduces your premium, lowers your deductible, and cuts copays, though not to zero

If your income dropped recently because of retirement, a spouse's death, or reduced work hours, apply even if you're unsure you qualify. SSA reviews your current income, not last year's, and people who were previously denied should reapply annually as income limits rise with inflation.

Compare Plans Every Fall During Open Enrollment

Medicare Part D plans change every year. Premiums, deductibles, covered drug lists (called formularies), and pharmacy networks can all shift on January 1. A plan that saved you money last year may cost significantly more in 2026, especially if your medications moved to a higher-cost tier or were dropped from the formulary altogether.

The Annual Enrollment Period (AEP) runs October 15 through December 7 each year. During this window you can switch standalone Part D plans or move between Original Medicare with a separate drug plan and a Medicare Advantage plan that includes drug coverage. New coverage starts January 1.

The free Medicare Plan Finder at Medicare.gov lets you enter your specific drugs, dosages, and preferred pharmacy to see your estimated total annual cost, premiums plus deductible plus all drug copays, for every plan available in your zip code. Always compare total annual cost, not just the monthly premium; a $0-premium plan can easily cost more overall if its copays are high.

When reviewing plans, pay attention to:

• Total estimated annual cost across premiums, deductible, and drug cost-sharing
• Whether your specific medications are on the formulary and which tier they occupy
• Prior authorization or step therapy requirements for any of your drugs
• In-network pharmacies and whether mail-order is available at a lower cost-share

To understand how the $2,000 cap interacts with different plan types, our guide on medicare out of pocket costs explains how cost-sharing accumulates across Original Medicare and Medicare Advantage drug benefits.

Use Generics, Tier Exceptions, and Negotiated Drug Prices

Part D plans organize covered drugs into pricing tiers. Generic drugs typically land on Tier 1 or Tier 2, with the lowest copays, often $0 to $15. Brand-name drugs sit on Tier 3 or higher, where you might pay 25 to 50 percent of the drug's cost. Moving even one medication down a tier can save hundreds of dollars a year on that drug alone.

Ask your doctor at your next appointment whether a generic exists for each medication you take. If not, ask whether a therapeutically similar drug in the same class is on a lower tier of your specific plan's formulary. Bring a printout of your plan's current drug list, available through the Medicare Plan Finder, to make the conversation concrete.

How to Request a Tier Exception

If no lower-tier alternative works for your medical condition, you can formally request a tier exception from your Part D plan. Your doctor submits a letter of medical necessity, and the plan must respond within 72 hours, or 24 hours for urgent requests. If approved, you pay the Tier 1 or Tier 2 cost-sharing rate for as long as the exception remains in effect. Your plan can provide its exception request form or process.

New Medicare-Negotiated Drug Prices Starting January 2026

Starting January 1, 2026, ten high-cost, widely used drugs carry Medicare-negotiated prices set by the Centers for Medicare & Medicaid Services (CMS) under the Inflation Reduction Act. These lower prices apply automatically at the pharmacy for anyone with Part D coverage, no forms or phone calls required on your part.

The ten drugs include Eliquis (apixaban), Jardiance (empagliflozin), Xarelto (rivaroxaban), Januvia (sitagliptin), Farxiga (dapagliflozin), Entresto (sacubitril/valsartan), Enbrel (etanercept), Imbruvica (ibrutinib), Stelara (ustekinumab), and Fiasp/NovoLog insulin. If you take any of these medications, ask your pharmacist in early January 2026 to confirm you're receiving the negotiated price at the register.

Additional Strategies That Add Up Over the Year

Mail-Order Pharmacies

If you take the same medications every month for ongoing conditions, blood pressure, cholesterol, diabetes, thyroid, or similar, mail-order is a simple, low-effort way to save. Many Part D plans charge two copays for a 90-day mail-order supply rather than charging three separate fill copays. For someone taking four maintenance drugs at $15 per copay, that's $60 saved per quarter, or $240 per year, simply by switching delivery method. Before making the switch, confirm your plan's exact mail-order cost-sharing, since some plans designate a preferred mail-order pharmacy with lower rates than standard options.

Medication Therapy Management Programs

Federal rules require Part D plans to offer free Medication Therapy Management (MTM) programs to members who have multiple chronic conditions, take several medications, and are likely to have high drug costs. An MTM session connects you with a pharmacist who reviews all your medications, looking for interactions, duplications, or drugs that cost more than equally effective alternatives. You receive a written summary and action plan you can take to your doctor.

Call your Part D plan and ask whether you qualify for an MTM review. It's a no-cost service that can identify both safety issues and savings opportunities at the same time.

State Pharmaceutical Assistance Programs

Many states offer their own drug assistance programs for seniors that stack on top of Medicare. Benefits vary: some programs pay Part D premiums; others cover specific drugs not on your formulary. A free State Health Insurance Assistance Program (SHIP) counselor in your area can tell you what your state offers. If you also have Medicaid, you may qualify for a Dual Eligible Special Needs Plan that coordinates both Medicare and Medicaid drug benefits, typically reducing copays to very low or zero amounts.
