Every fall, the Centers for Medicare and Medicaid Services releases the official premium and deductible figures that govern what Medicare beneficiaries pay out of pocket in the coming year. For 2026, those numbers are finalized, and they carry real financial consequences for the roughly 67 million Americans enrolled in Medicare. Whether you carry Original Medicare alone, pair it with a Medigap supplement, or belong to a Medicare Advantage plan that uses Original Medicare cost-sharing as its baseline, these figures define your financial exposure from January 1 onward. Understanding each number — and knowing which programs can reduce what you owe — is the most practical thing you can do before the new year begins.
The standard monthly Part B premium for 2026 is $185.00, up from $174.70 in 2025. That is an increase of $10.30 per month, or $123.60 over the full year. For most beneficiaries, this amount is automatically deducted from their Social Security payment, so the increase will appear as a smaller net deposit starting in January 2026. If you are not yet collecting Social Security and pay your premium directly to Medicare, you will see the new amount on your quarterly or monthly billing statement. Part B covers outpatient services, physician visits, preventive screenings, durable medical equipment, and drugs administered in a clinical setting such as chemotherapy infusions — essentially everything Medicare covers outside of an inpatient hospital stay.
Higher-income beneficiaries pay more through a surcharge called the Income-Related Monthly Adjustment Amount, or IRMAA. In 2026, IRMAA applies to individuals with modified adjusted gross income above $106,000 and to married couples filing jointly above $212,000, calculated from your 2024 federal tax return. The surcharges are tiered: an individual earning between $106,000 and $133,000 pays a total Part B premium of $259.00 per month, while someone earning between $133,000 and $167,000 pays $370.00. At the highest income tier — individuals above $500,000 or couples above $750,000 — the total Part B premium reaches $628.90 per month. If you received an IRMAA notice and your income has dropped significantly since 2024 due to retirement, divorce, loss of a spouse, or reduction in work hours, you can file Form SSA-44 with the Social Security Administration to request a reduction based on more recent income. This step is frequently overlooked and can save several hundred dollars per month for those who qualify.
The Part B annual deductible for 2026 is $257, up from $240 in 2025. You pay this amount entirely out of pocket before Medicare begins covering 80 percent of approved outpatient costs. After the deductible is met, you remain responsible for the remaining 20 percent coinsurance with no annual cap under Original Medicare alone. That uncapped 20 percent exposure is particularly significant for beneficiaries receiving cancer treatment, dialysis, or other high-frequency outpatient services where costs accumulate quickly. A single course of chemotherapy can generate tens of thousands of dollars in approved charges, leaving the beneficiary responsible for thousands in coinsurance unless a Medigap policy or Medicare Advantage plan limits that exposure.
On the hospital side, the Part A inpatient deductible for 2026 is $1,676 per benefit period, up from $1,632 in 2025. This is not an annual deductible — it resets with each new benefit period, which begins when you are admitted to a hospital and ends only after you have been out of the hospital or skilled nursing facility for 60 consecutive days. If you are hospitalized in February, recover fully, and are hospitalized again in September, you face the $1,676 deductible a second time. For days 1 through 60 of a single hospital stay, that deductible is your only cost-sharing. From day 61 through day 90, you pay $419 per day in coinsurance. If you exhaust your 90 covered days and draw on your 60 lifetime reserve days, coinsurance rises to $838 per day. Once lifetime reserve days are gone, Medicare pays nothing for inpatient hospital care, and you bear the full daily cost.
Skilled nursing facility coverage under Part A follows a tiered structure that surprises many families. Medicare covers the full cost of a skilled nursing facility stay for days 1 through 20, but only following a qualifying inpatient hospital stay of at least three consecutive days — observation status does not count. From day 21 through day 100, you pay $209.50 per day in coinsurance in 2026. After day 100, Medicare coverage ends entirely, and the full daily rate at a skilled nursing facility — which commonly runs $300 to $500 per day depending on location and level of care — falls to you. Long-term care insurance or Medicaid may cover costs beyond that threshold for those who qualify, but Original Medicare does not. This gap is one of the most consequential and least understood in the entire Medicare program.
For beneficiaries enrolled in a Medigap supplemental policy, many of these cost-sharing amounts are covered automatically depending on which plan letter you hold. Medigap Plan G, the most comprehensive plan available to beneficiaries who became eligible for Medicare on or after January 1, 2020, covers the Part A deductible, Part A coinsurance, Part B coinsurance, skilled nursing facility coinsurance, and foreign travel emergency care — but not the Part B deductible of $257. Medigap Plan N covers similar benefits but requires copays of up to $20 for office visits and up to $50 for emergency room visits that do not result in an inpatient admission. Plan F, which covers the Part B deductible as well, remains available only to beneficiaries who were eligible for Medicare before January 1, 2020. Medigap premiums vary considerably by insurer, age, tobacco use, and geographic location, so comparing quotes annually through your State Health Insurance Assistance Program — known as SHIP — can reveal whether your current plan is still competitively priced or whether switching could reduce your monthly cost.
If you are enrolled in a Medicare Advantage plan rather than Original Medicare, your plan's specific copays and deductibles may differ from the figures above, since Medicare Advantage plans set their own cost-sharing structures within CMS guidelines. However, the Part B premium still applies regardless of which plan you choose — you pay it in addition to any Medicare Advantage plan premium. In 2026, many Medicare Advantage plans continue to offer $0 additional premiums in competitive markets, but those plans come with provider networks, referral requirements, and prior authorization processes that Original Medicare does not impose. Your plan's Annual Notice of Change, mailed each fall before the Annual Enrollment Period, specifies exactly what your plan's deductibles, copays, and out-of-pocket maximum will be for the coming year. Reading it carefully before October 15 gives you time to switch if the terms have changed unfavorably.
The Annual Enrollment Period runs October 15 through December 7 each year. During this window, you can switch from Original Medicare to Medicare Advantage or back, change your Part D prescription drug plan, or move between Medicare Advantage plans. Changes take effect January 1. If you miss this window, the Open Enrollment Period from January 1 through March 31 allows Medicare Advantage enrollees to switch to a different Advantage plan or return to Original Medicare, with changes effective the first day of the following month. Outside of these windows, switching typically requires a qualifying life event or a guaranteed issue right.
Beneficiaries with limited incomes and assets may qualify for Medicare Savings Programs administered through their state Medicaid agency. These programs can pay some or all of your Part B premium and, in the case of the Qualified Medicare Beneficiary program, also cover Part A and Part B deductibles and coinsurance. In 2026, the QMB income limit is approximately $1,255 per month for individuals and $1,704 per month for couples, though some states have expanded eligibility beyond federal minimums. The Specified Low-Income Medicare Beneficiary program covers the Part B premium for individuals with income up to roughly $1,478 per month, and the Qualifying Individual program extends that premium assistance to individuals with income up to approximately $1,660 per month. Applying through your state Medicaid office costs nothing, and if approved, benefits are applied retroactively to the month you submitted your application. Many eligible beneficiaries never apply simply because they are unaware the programs exist.
The Extra Help program — also called the Low Income Subsidy — is a separate federal program that reduces Part D prescription drug costs for beneficiaries with income below roughly 150 percent of the federal poverty level. In 2026, full Extra Help can reduce your Part D premium to zero or near zero and cap your drug copays at $4.90 for generics and $12.15 for brand-name drugs. You can apply through the Social Security Administration at ssa.gov or by calling 1-800-772-1213. If you already receive Medicaid, Supplemental Security Income, or participate in a Medicare Savings Program, you are automatically enrolled in Extra Help and do not need to apply separately. Enrollment in Extra Help also qualifies you for a Special Enrollment Period to change your Part D plan outside the standard enrollment windows.
For beneficiaries trying to understand how all of these changes interact with their specific situation, the Medicare Plan Finder tool at medicare.gov allows you to compare plans, estimate annual drug costs, and review coverage options based on your zip code and the medications you take. Your State Health Insurance Assistance Program provides free, unbiased counseling from trained volunteers who can walk through your options without any financial interest in what you choose. To find your local SHIP counselor, visit shiphelp.org or call 1-800-MEDICARE (1-800-633-4227). These counselors are especially valuable during the Annual Enrollment Period, when the volume of plan changes and marketing materials can make it difficult to evaluate options objectively.
Planning ahead for these cost increases matters most for beneficiaries on fixed incomes. A $10.30 monthly increase in the Part B premium may appear modest in isolation, but combined with a $44 increase in the Part A deductible, higher skilled nursing coinsurance, and potential IRMAA surcharges, the cumulative effect on a household budget can be substantial. Reviewing your Medicare coverage each fall — before a health crisis forces the issue — gives you the best opportunity to align your plan with your actual health needs and financial situation before January 1 arrives.
