What Medicare Will Cost You in 2026: Every Number You Need

If you're on Medicare in 2026, you're navigating a cost structure that looks meaningfully different from even two years ago. Premiums are up, deductibles have shifted, and one of the biggest changes in Medicare's drug coverage history — the $2,000 annual out-of-pocket cap on Part D prescription costs — is now fully in effect. Understanding exactly what you owe, when you owe it, and how to plan around it can save you hundreds or even thousands of dollars over the course of the year.

Let's start with Part B, which covers your doctor visits, outpatient care, and most preventive services. The standard monthly Part B premium in 2026 is $185.00, up from $174.70 in 2025. That increase of roughly $10 per month may sound modest, but it adds up to about $120 more per year — and for couples, that's $240 annually coming out of Social Security checks or bank accounts. The Part B annual deductible in 2026 is $257, up from $240 in 2025. After you meet that deductible, Medicare typically covers 80% of approved outpatient costs, leaving you responsible for the remaining 20% with no cap unless you have a Medigap supplemental policy.

That 20% coinsurance with no ceiling is one of the most important — and most misunderstood — features of Original Medicare. If you have a $50,000 outpatient surgery or a prolonged course of chemotherapy billed under Part B, your 20% share could reach $10,000 or more. This is precisely why Medigap plans (also called Medicare Supplement Insurance) exist. Plans like Medigap Plan G, which is the most comprehensive option available to beneficiaries who became eligible for Medicare after January 1, 2020, cover that 20% coinsurance, the Part B deductible in some plan types, and most other cost-sharing gaps in Original Medicare. Monthly premiums for Plan G vary widely by age, location, and insurer — ranging from roughly $100 to over $300 per month — but for beneficiaries with significant healthcare needs, the math often favors the coverage.

On the hospital side, Part A covers inpatient stays, skilled nursing facility care, hospice, and some home health services. Most people don't pay a monthly premium for Part A if they or their spouse worked and paid Medicare taxes for at least 10 years (40 quarters). But Part A does come with a deductible: in 2026, the Part A inpatient hospital deductible is $1,676 per benefit period. Here's the critical detail that trips up many beneficiaries — this is not an annual deductible. A benefit period begins the day you're admitted to a hospital and ends when you've been out of the hospital or skilled nursing facility for 60 consecutive days. If you're hospitalized twice in the same calendar year with more than 60 days between stays, you owe the $1,676 deductible twice. For days 61 through 90 of a hospital stay, you also pay a daily coinsurance of $419 in 2026. Beyond 90 days, you can draw on your 60 lifetime reserve days, at a coinsurance of $838 per day.

Skilled nursing facility coverage under Part A follows its own cost schedule. The first 20 days in a qualifying SNF stay are fully covered by Medicare. Days 21 through 100 require a daily coinsurance of $209.50 in 2026. After day 100, Medicare pays nothing — all costs fall to you or your supplemental coverage. This is a scenario that catches many families off guard during recovery from a hip replacement or stroke, when extended rehabilitation is needed. Planning ahead by understanding these thresholds — and knowing whether your Medigap plan covers SNF coinsurance — can prevent financial shock during an already stressful time.

Now for the Part D news that represents a genuine milestone in Medicare history. Starting in 2026, the Inflation Reduction Act's $2,000 annual out-of-pocket cap on Part D prescription drug costs is fully in place. This means that once you've spent $2,000 out of pocket on covered drugs in a calendar year, your Part D plan pays 100% of covered drug costs for the rest of the year — no exceptions, no catastrophic phase cost-sharing. For beneficiaries who take expensive brand-name medications for conditions like rheumatoid arthritis, cancer, or multiple sclerosis, this change can be transformative. Previously, some beneficiaries were spending $5,000, $7,000, or more annually on medications before reaching catastrophic coverage. The $2,000 cap eliminates that exposure entirely. Additionally, the Medicare Prescription Payment Plan — also called the smoothing option — allows you to spread your out-of-pocket drug costs across monthly installments throughout the year rather than paying large lump sums at the pharmacy counter.

For higher-income beneficiaries, the Income-Related Monthly Adjustment Amount, known as IRMAA, adds a surcharge on top of both Part B and Part D premiums. IRMAA is based on your modified adjusted gross income from two years prior — so your 2026 surcharges are calculated from your 2024 tax return. In 2026, single filers with income above $106,000 and married couples filing jointly with income above $212,000 pay more than the standard Part B premium. The surcharges are tiered: at the highest income bracket (individuals earning more than $500,000, or couples above $750,000), the total Part B premium reaches $628.90 per month per person. If you've had a significant income reduction since 2024 — due to retirement, the death of a spouse, or other life events — you can file Form SSA-44 with the Social Security Administration to request a reduction in your IRMAA surcharge based on more recent income.

One area where beneficiaries often leave money on the table involves Extra Help, the federal program that subsidizes Part D costs for people with limited income and resources. In 2026, individuals with annual income below roughly $22,590 and resources below $17,220 (with higher thresholds for married couples) may qualify for Extra Help, which can reduce or eliminate Part D premiums, deductibles, and copayments. Enrollment in Extra Help is handled through the Social Security Administration at ssa.gov, and eligibility is also automatically extended to people enrolled in Medicaid or who receive Supplemental Security Income. If your income is near these thresholds, it's worth applying — the program is underutilized, and many eligible beneficiaries don't realize they qualify.

Finally, if you're comparing Original Medicare to Medicare Advantage for 2026, the cost picture is more nuanced than it appears. Many Medicare Advantage plans advertise $0 premiums, but those plans still require you to pay your Part B premium, and they come with their own cost-sharing structures — copayments, coinsurance, and network restrictions — that can add up quickly if you use significant healthcare services. Original Medicare with a Medigap plan offers more predictable costs and broader provider access, but typically costs more in monthly premiums. The right choice depends on your health status, how often you see specialists, whether your doctors are in a given Advantage plan's network, and your financial tolerance for unpredictable out-of-pocket costs. Medicare's Plan Finder tool at medicare.gov allows you to compare plans side by side using your actual medications and preferred providers — it's the most reliable starting point for making this decision with real numbers rather than marketing materials.
