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

If you're on Medicare in 2026, your costs went up again — and understanding exactly where those increases hit is the difference between a budget surprise and a plan you can manage. The Centers for Medicare & Medicaid Services (CMS) finalized the 2026 Medicare cost figures, and while the increases are not dramatic, they compound on top of several years of rising premiums and deductibles. Here's a plain-language breakdown of every number that affects your wallet, and what it means for people weighing Original Medicare against Medicare Advantage.

The standard Medicare Part B premium for 2026 is $185.00 per month. That's up $10.30 from the $174.70 monthly premium in 2025. Part B covers outpatient care — your doctor visits, lab work, preventive screenings, durable medical equipment, and most outpatient procedures. Nearly everyone on Medicare pays this premium, and for most beneficiaries it's automatically deducted from their Social Security check. If your income is above certain thresholds, you pay more through what's called IRMAA — the Income-Related Monthly Adjustment Amount. In 2026, IRMAA surcharges kick in for individuals with modified adjusted gross income above $106,000 and for married couples filing jointly above $212,000. At the highest income tier, the Part B premium can reach $628.90 per month. If you had a significant income drop in 2024 or 2025 due to retirement, divorce, or a spouse's death, you can appeal your IRMAA determination using IRS Form SSA-44 — many beneficiaries don't realize this option exists and overpay for months.

The Part B annual deductible in 2026 is $257, up from $240 in 2025. You pay this amount out of pocket before Medicare begins covering 80 percent of approved outpatient costs. That 20 percent coinsurance with no cap is one of the most important features of Original Medicare to understand — because there is no out-of-pocket maximum under traditional Medicare Parts A and B. A serious illness or extended outpatient treatment can result in thousands of dollars in coinsurance with no ceiling. This is why Medigap (Medicare Supplement) plans exist, and it's also a core reason many beneficiaries find Medicare Advantage appealing.

On the hospital side, the Medicare Part A deductible for inpatient care rose to $1,676 per benefit period in 2026, up from $1,632 in 2025. This is not an annual deductible — it resets every benefit period, which begins when you're admitted to a hospital and ends after you've been out of the hospital or skilled nursing facility for 60 consecutive days. If you're hospitalized twice in a year with more than 60 days between stays, you could owe this deductible twice. Days 1 through 60 of a hospital stay are covered after that deductible. From day 61 through day 90, you pay $419 per day in coinsurance in 2026. Beyond 90 days, you draw on your 60 lifetime reserve days at $838 per day. Skilled nursing facility care has its own cost structure: days 1 through 20 are fully covered after a qualifying hospital stay, but days 21 through 100 carry a $209.50 per day coinsurance charge in 2026.

Now here's where Medicare Advantage changes the calculation significantly. Medicare Advantage plans — also called Part C — are sold by private insurers approved by CMS and must cover everything Original Medicare covers, but they typically bundle in additional benefits and restructure how you pay for care. In 2026, CMS set the maximum out-of-pocket limit for Medicare Advantage plans at $9,350 for in-network services. Some plans set their caps lower — many competitive plans in urban markets cap out-of-pocket costs between $4,000 and $6,500 annually. Once you hit that cap, the plan pays 100 percent of covered in-network costs for the rest of the year. This ceiling is something Original Medicare simply does not offer, and for beneficiaries managing chronic conditions or anticipating surgery, it can represent meaningful financial protection.

Most Medicare Advantage plans in 2026 continue to charge $0 in monthly premiums beyond the Part B premium you're already paying — though $0-premium plans have become somewhat less common as insurers recalibrate benefits following CMS payment adjustments. When comparing plans, don't let a $0 premium be the only factor. Look at the plan's annual deductible (some MA plans have $0 deductibles, others charge up to $600 or more), the copays for primary care and specialist visits, the drug formulary if the plan includes Part D, and whether your specific doctors and preferred hospitals are in-network. A plan with a $0 premium but a $50 specialist copay and a narrow network may cost you more than a plan with a $40 monthly premium and $10 specialist visits — especially if you see specialists regularly.

Prescription drug costs under Medicare Part D — whether as a standalone plan or embedded in a Medicare Advantage plan — saw a significant structural change take full effect in 2026 following the Inflation Reduction Act. The catastrophic coverage phase now means your annual out-of-pocket cap for Part D drugs is $2,000 in 2026. Once you've spent $2,000 on covered drugs, you pay nothing for the rest of the year. This is a major improvement from prior years when there was effectively no cap on drug costs for high-utilization patients. The Part D deductible maximum in 2026 is $590, though many plans charge less or waive it for certain drug tiers.

For beneficiaries considering a switch, the Annual Enrollment Period runs October 15 through December 7 each year, with coverage changes taking effect January 1. If you're already in a Medicare Advantage plan and want to switch to a different MA plan or return to Original Medicare, the Open Enrollment Period from January 1 through March 31 gives you one additional opportunity. Changes made during OEP take effect the first day of the following month. Outside these windows, you generally need a Special Enrollment Period triggered by a qualifying event — moving out of your plan's service area, losing employer coverage, or qualifying for Extra Help with drug costs, among others.

If you're on Original Medicare and considering adding a Medigap policy to cover that uncapped 20 percent coinsurance, timing matters enormously. Your guaranteed-issue window — when insurers cannot deny you coverage or charge more based on health conditions — is the six-month period that begins the month you turn 65 and are enrolled in Part B. Outside that window, insurers in most states can use medical underwriting, meaning a pre-existing condition could result in a higher premium or outright denial. Thirteen states have additional protections: California, Idaho, Illinois, Kentucky, Louisiana, Maine, Maryland, Missouri, Nevada, New Jersey, New York, Oklahoma, and Oregon all have birthday rules or continuous open enrollment provisions that give you a window each year to switch Medigap plans without medical underwriting. If you live in one of these states, check with your state insurance commissioner's office for the specific rules, as the window length and eligible plan types vary by state.

The bottom line for 2026 is this: Original Medicare costs more than it did last year, and it still offers no out-of-pocket maximum. Medicare Advantage provides that ceiling but requires you to navigate networks, prior authorizations, and annual plan changes. Neither path is universally better — the right choice depends on your health needs, your doctors, your prescriptions, and your financial situation.
