Medicare Part A Costs Jump Nearly 10% in 2026: What You'll Pay

Medicare's Part A costs are climbing again in 2026, and the increase is steep enough that beneficiaries relying solely on Original Medicare need to pay close attention. The inpatient hospital deductible — the amount you pay before Medicare covers a single day of a hospital stay — has risen to $1,676 for 2026. That is up from $1,632 in 2025, a $44 jump that continues a pattern of year-over-year increases that have added hundreds of dollars to the deductible over the past decade. For context, the Part A deductible was $1,408 in 2021. In five years, it has grown by $268, or roughly 19%. That is not a rounding error — it is a meaningful shift in what seniors owe when they end up in the hospital.

Understanding how the Part A deductible actually works is essential, because it operates differently from most insurance deductibles you may have had during your working years. Unlike a calendar-year deductible that resets every January 1, Medicare's Part A deductible is tied to something called a benefit period. A benefit period begins the day you are admitted to a hospital as an inpatient and ends after you have been out of the hospital — or a skilled nursing facility — for 60 consecutive days. If you are readmitted after that 60-day gap, a brand new benefit period begins, and you owe the full $1,676 deductible again. There is no cap on how many benefit periods you can have in a single year. A beneficiary who has two separate hospitalizations with more than 60 days between them could owe $3,352 in Part A deductibles alone in 2026.

Beyond the deductible, the coinsurance structure for longer hospital stays also deserves attention. For days 1 through 60 of a hospital stay within a benefit period, Medicare covers everything after the deductible. But starting on day 61, you owe $419 per day in coinsurance in 2026 — up from $408 in 2025. For days 91 through 150, you are drawing on your lifetime reserve days, and the daily coinsurance jumps to $838 in 2026. Once those 60 lifetime reserve days are exhausted, Medicare pays nothing, and you are responsible for the full cost of the stay. These numbers matter most for beneficiaries managing serious conditions like cancer, heart failure, or stroke recovery, where extended hospitalizations are more likely.

Skilled nursing facility costs are also affected by the same benefit period structure. After a qualifying hospital stay of at least three days, Medicare covers skilled nursing facility care fully for days 1 through 20. Starting on day 21, you owe $209.50 per day in coinsurance in 2026 — a figure that adds up quickly for someone recovering from a hip replacement or a stroke. A 45-day skilled nursing stay, which is not unusual after major surgery, would cost a beneficiary roughly $5,237.50 in coinsurance under 2026 rates, after the first 20 days are covered. That is a significant financial exposure for someone on a fixed income.

The question most beneficiaries should be asking is: what coverage do I have that protects me from these costs? If you have a Medigap (Medicare Supplement) policy, your exposure may be dramatically reduced or eliminated depending on the plan type. Medigap Plan G, one of the most popular options available to beneficiaries who became eligible for Medicare after January 1, 2020, covers the Part A deductible, the Part A coinsurance, and skilled nursing facility coinsurance in full. In 2026, a Plan G policyholder who is hospitalized pays nothing beyond their monthly premium, regardless of how long the stay lasts. Medigap Plan N covers the Part A deductible and coinsurance but requires small copays for some doctor visits. Plan A, the most basic Medigap option, covers coinsurance but not the deductible itself — meaning you would still owe the $1,676 upfront.

If you are enrolled in a Medicare Advantage plan rather than Original Medicare, the Part A deductible structure does not apply in the same way. Medicare Advantage plans set their own cost-sharing rules, which are approved annually by CMS. Many Advantage plans charge a flat daily copay for hospital stays — commonly $0 to $350 per day for the first several days — rather than a single large deductible. However, Advantage plans also have their own annual out-of-pocket maximums, which in 2026 can be as high as $9,350 for in-network services. Whether an Advantage plan or Original Medicare with a Medigap supplement offers better financial protection depends heavily on your health status, the providers in your area, and how frequently you use hospital services.

For beneficiaries currently enrolled in Original Medicare without any supplement, the 2026 cost increases are a strong signal to evaluate your options. The Annual Enrollment Period runs from October 15 through December 7 each year, and it allows you to switch from Original Medicare to a Medicare Advantage plan, or to switch between Advantage plans. However, moving from Medicare Advantage back to Original Medicare and then purchasing a Medigap policy is more complicated — in most states, insurers can use medical underwriting to deny you coverage or charge higher premiums based on your health history if you are outside your initial enrollment window. The exceptions are the 13 states with birthday rule protections — 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 medical underwriting.

If you are newly enrolling in Medicare, your Initial Enrollment Period — the seven-month window surrounding your 65th birthday — is when you have guaranteed issue rights to purchase any Medigap plan sold in your state, regardless of health history. Missing this window and enrolling later without a qualifying Special Enrollment Period can make it significantly harder and more expensive to obtain supplement coverage. CMS encourages beneficiaries to use the Medicare Plan Finder tool at Medicare.gov to compare Medigap premiums in their ZIP code, which can vary by hundreds of dollars per month for the same plan type depending on the insurer and your location.

The broader trend driving these cost increases is worth understanding. Medicare Part A costs are recalculated annually by CMS based on projected hospital costs, utilization rates, and the overall financial status of the Medicare Hospital Insurance Trust Fund. As hospital prices and labor costs have risen sharply since 2021, those increases have flowed through to beneficiary cost-sharing. The Part A deductible has no statutory cap — it is set by formula, not by Congress — which means it will continue to rise as long as underlying hospital costs do. Advocacy organizations including AARP have called for restructuring Medicare's cost-sharing to include an annual out-of-pocket cap for Original Medicare, similar to what Advantage plans are required to offer, but no such change has been enacted as of 2026.

For practical next steps: pull out your current Medicare card or plan documents and identify exactly what coverage you have. If you are in Original Medicare with no supplement, call 1-800-MEDICARE or visit Medicare.gov to use the Plan Finder and compare Medigap options in your area. If you have a Medigap policy, verify which plan letter you hold and confirm it covers the Part A deductible — not all plans do. If you are in a Medicare Advantage plan, review your Summary of Benefits document for your 2026 hospital inpatient cost-sharing terms, which your plan is required to mail you each fall. Understanding exactly what you owe before a hospitalization — not during one — is the most effective way to protect yourself from a bill that has just gotten meaningfully larger.
