Medicare 2026: 3 Cost Changes Every Beneficiary Needs to Know

Three significant cost changes took effect in Medicare in 2026, and together they represent the most consequential shift in what beneficiaries pay — particularly for prescription drugs — in the program's history. If you haven't reviewed your plan or your budget since last year, now is the time, because some of these changes put money back in your pocket while others quietly take a little more out.

The single biggest change is the new $2,000 annual out-of-pocket cap on Medicare Part D prescription drug costs. Starting January 1, 2026, once you've paid $2,000 in covered drug costs under a Part D plan — whether that's a standalone drug plan or the drug coverage built into a Medicare Advantage plan — your plan covers 100% of your remaining drug costs for the rest of the year. This is a direct result of the Inflation Reduction Act, and it's a dramatic improvement over prior years. In 2024, beneficiaries could face catastrophic drug costs well above $8,000 before hitting true out-of-pocket protection. In 2025, a $2,000 cap was introduced as a transitional step, and 2026 locks that figure in as the permanent standard. For the roughly 3.3 million Medicare beneficiaries who previously hit the catastrophic coverage phase each year, this change can mean thousands of dollars in annual savings.

It's important to understand what counts toward that $2,000 cap and what doesn't. Your deductible payments, copays, and coinsurance for covered drugs all count. What does not count is your monthly Part D premium — that's a separate cost you pay regardless of how much you use your coverage. The $2,000 cap also applies only to drugs on your plan's formulary. If your medication isn't covered by your specific plan, those costs don't count toward the cap, which is one reason it's worth double-checking that your current plan still covers your prescriptions at the start of each year. You can verify formulary coverage at Medicare.gov's Plan Finder tool or by calling 1-800-MEDICARE.

The second major change involves the Medicare Prescription Payment Plan, a new option that became available in 2025 and continues in 2026. This program allows Part D enrollees to spread their out-of-pocket drug costs across monthly payments throughout the calendar year rather than paying a large sum all at once at the pharmacy counter. Think of it as an interest-free installment plan for your drug costs. If you take an expensive specialty medication and typically face a $600 copay in January when you first fill a prescription, the Prescription Payment Plan lets you break that into smaller monthly payments spread across the remaining months of the year. You must opt in — it's not automatic — and you do so through your Part D plan. Contact your plan directly or visit their website to enroll. This option is particularly valuable for people on fixed incomes who struggle with large upfront costs even if their total annual drug spending stays under the $2,000 cap.

The third change is less welcome: Medicare Part B premiums increased in 2026. Part B covers your doctor visits, outpatient services, lab work, and durable medical equipment. The standard monthly Part B premium in 2026 is $185.00, up from $174.70 in 2025. That's an increase of $10.30 per month, or about $123.60 more per year. For most beneficiaries, this premium is automatically deducted from your Social Security check, so you may have noticed your net payment dropped slightly at the start of the year. The Part B annual deductible also increased to $257 in 2026, up from $240 in 2025. You pay this deductible once per year before Medicare begins covering its 80% share of approved services.

Higher-income beneficiaries pay more than the standard Part B premium through a surcharge called IRMAA — the Income-Related Monthly Adjustment Amount. In 2026, IRMAA surcharges apply if your modified adjusted gross income from two years ago (meaning your 2024 tax return) exceeded $106,000 for an individual or $212,000 for a married couple filing jointly. At the highest income tier, the total Part B premium can reach $628.90 per month per person in 2026. If your income has dropped significantly since 2024 — due to retirement, the death of a spouse, or other life changes — you can appeal your IRMAA determination by filing Form SSA-44 with the Social Security Administration. This is a step many beneficiaries don't know they can take, and it can result in meaningful premium reductions.

For people enrolled in Medicare Advantage plans rather than Original Medicare, these changes interact somewhat differently. The $2,000 Part D cap applies to Medicare Advantage plans that include drug coverage (called MA-PD plans), which is the majority of Medicare Advantage enrollees. However, Medicare Advantage plans set their own cost-sharing structures for medical services — copays, coinsurance, and out-of-pocket maximums — and those figures vary widely by plan and by county. The maximum out-of-pocket limit for in-network services under Medicare Advantage plans in 2026 is $9,350, though many plans set lower limits. If you're in a Medicare Advantage plan, your Summary of Benefits document, which your plan mailed to you in the fall, spells out your specific cost-sharing for 2026.

If you're in Original Medicare with a standalone Part D drug plan, the $2,000 cap is straightforward: it applies to your drug plan's covered medications. Your medical costs under Original Medicare — the 20% coinsurance for Part B services, for example — are separate and not subject to any annual cap unless you also carry a Medigap supplemental policy. Medigap plans (also called Medicare Supplement Insurance) cover some or all of that 20% coinsurance, and they continue to be sold under standardized letter plans (Plan G, Plan N, and others) with premiums that vary by insurer, your age, and your location.

If you missed the Annual Enrollment Period (October 15 through December 7, 2025) and want to make changes now, you still have options. The Medicare Advantage Open Enrollment Period runs January 1 through March 31 each year. During this window, people already enrolled in a Medicare Advantage plan can switch to a different Medicare Advantage plan or return to Original Medicare and add a Part D drug plan. You cannot, however, use this window to switch from Original Medicare into Medicare Advantage. For Medigap coverage, switching plans typically requires passing medical underwriting unless you live in one of the states with a birthday rule — California, Idaho, Illinois, Kentucky, Louisiana, Maine, Maryland, Missouri, Nevada, New Jersey, New York, Oklahoma, and Oregon — where you have a 30-day window around your birthday each year to switch Medigap plans without health questions.
