Medicare Costs Are Rising in 2026: What You'll Pay for Parts A, B & D

If you're on Original Medicare and your Social Security check felt a little lighter this year, you're not imagining it. Medicare costs went up again in 2026, and for many beneficiaries — especially those on fixed incomes — the increases are real money. The standard Part B premium is now $185.00 per month, the Part A inpatient hospital deductible has climbed, and the Part D landscape has shifted in ways that affect what you pay at the pharmacy counter. Understanding exactly what changed, and why, can help you make smarter decisions about your coverage for the rest of the year.

Let's start with Part B, because that's where most beneficiaries feel the pinch first. The standard monthly premium for Medicare Part B in 2026 is $185.00, up from $174.70 in 2025. That's a $10.30 per month increase, which translates to $123.60 more per year — per person. For a married couple where both spouses are on Medicare, that's nearly $250 more annually just in premiums. The Part B annual deductible also rose, from $240 in 2025 to $257 in 2026. You must meet this deductible before Medicare starts paying its 80% share of covered outpatient services, including doctor visits, lab work, outpatient surgery, and durable medical equipment.

Part A — the hospital insurance portion of Medicare — also saw cost increases in 2026. The inpatient hospital deductible, which applies per benefit period (not per year), rose to $1,676 in 2026, up from $1,632 in 2025. This deductible covers your first 60 days in the hospital during a single benefit period. If you're hospitalized for more than 60 days, coinsurance kicks in: $419 per day for days 61 through 90, and $838 per day for lifetime reserve days beyond that. Most people don't pay a Part A premium because they or their spouse worked and paid Medicare taxes for at least 40 quarters (10 years). But if you have fewer than 30 quarters of work history, the Part A premium in 2026 is $518 per month — and if you have 30 to 39 quarters, it's $284 per month.

For beneficiaries with higher incomes, the cost increases are even more pronounced. Medicare uses a system called Income-Related Monthly Adjustment Amounts, or IRMAA, to charge higher premiums to individuals and couples whose income exceeds certain thresholds. IRMAA is based on your modified adjusted gross income (MAGI) from two years prior — so your 2026 premiums are based on your 2024 tax return. In 2026, individuals with income above $106,000 (or couples above $212,000) begin paying IRMAA surcharges on top of the standard Part B premium. At the highest income tier — individuals earning more than $500,000 or couples earning more than $750,000 — the total Part B premium reaches $628.90 per month per person. IRMAA also applies to Part D drug coverage, adding anywhere from $13.70 to $85.80 per month on top of your plan's regular premium depending on your income bracket. If your income dropped significantly since 2024 due to retirement, divorce, or the death of a spouse, you can appeal your IRMAA determination using IRS Form SSA-44 — and many beneficiaries successfully have their surcharges reduced or eliminated.

Data Snapshot: According to CMS.gov data, Medicare Part B enrolled approximately 67 million Americans as of 2025, making the annual premium adjustment one of the most broadly felt cost changes in the entire U.S. healthcare system. CMS also reported that in 2026, the Medicare Advantage market offered beneficiaries an average of 40 plan options per county, though premiums, deductibles, and network structures vary widely by region. The average Medicare Advantage plan premium in 2026 was approximately $17 per month — a figure that makes the $185 Part B premium comparison especially relevant for beneficiaries weighing their coverage options.

Part D prescription drug coverage also saw meaningful changes in 2026, building on the reforms introduced by the Inflation Reduction Act. The most significant structural change is the new $2,000 annual out-of-pocket cap on Part D drug costs, which took full effect in 2026. This is a landmark protection for beneficiaries who take expensive brand-name or specialty medications — previously, there was no hard cap, and some people spent $5,000 or more per year on drugs before catastrophic coverage kicked in. The standard Part D deductible in 2026 is $590, though many plans set their deductible lower or waive it entirely for certain drug tiers. The Medicare Prescription Payment Plan, also known as the smoothing option, allows beneficiaries to spread their out-of-pocket drug costs across monthly installments throughout the year rather than paying large lump sums when filling expensive prescriptions.

One of the most important things to understand about these cost increases is why they happen. CMS sets Medicare premiums and deductibles each fall, and the adjustments are driven primarily by projected healthcare spending, changes in Medicare utilization, and the cost of new medical treatments entering the market. High-cost drugs — particularly new Alzheimer's treatments and GLP-1 medications — have put upward pressure on Part B costs because drugs administered in a doctor's office are covered under Part B, not Part D. When Medicare begins covering expensive infusion therapies or injectable medications at scale, the cost gets spread across all Part B enrollees through higher premiums. This is why your premium can rise even if you personally never use those treatments.

If you have a Medigap (Medicare Supplement) policy, these deductible increases may or may not affect your wallet directly, depending on which plan letter you hold. Medigap Plan G, currently the most comprehensive plan available to new Medicare enrollees, covers the Part B excess charges and all costs after the Part B deductible — meaning once you pay your $257 deductible, Plan G picks up the remaining 20% coinsurance for the rest of the year. Medigap Plan N covers the same costs but requires copays of up to $20 for office visits and up to $50 for emergency room visits. Plan F, which covers the Part B deductible entirely, is no longer available to beneficiaries who became eligible for Medicare on or after January 1, 2020 — but if you enrolled in Plan F before that date, you can keep it. Medigap premiums vary significantly by state, age, and insurer, but average monthly premiums for Plan G nationally range from roughly $100 to $200 per month for a 65-year-old, according to industry data.

For beneficiaries with limited income and resources, there are programs specifically designed to offset these rising costs. The Medicare Savings Programs (MSPs) — administered through your state Medicaid office — can pay your Part B premium, and in some cases your Part A premium and cost-sharing, if you qualify based on income and assets. There are four MSP levels: the Qualified Medicare Beneficiary (QMB) program, the Specified Low-Income Medicare Beneficiary (SLMB) program, the Qualifying Individual (QI) program, and the Qualified Disabled and Working Individuals (QDWI) program. QMB is the most comprehensive, covering Part A and Part B premiums, deductibles, and coinsurance. Income limits vary by state, but in 2026 the federal baseline for QMB eligibility is roughly $1,255 per month for individuals and $1,704 for couples. Many states have higher limits. The Extra Help program (also called the Low-Income Subsidy, or LIS) can similarly reduce or eliminate Part D premiums and cost-sharing for qualifying beneficiaries. You can apply for Extra Help through the Social Security Administration at ssa.gov, and for Medicare Savings Programs through your state Medicaid office.

If you're currently enrolled in Original Medicare without a Medigap policy, the 2026 cost increases are a good prompt to reconsider your coverage structure. Without supplemental coverage, you're responsible for the 20% coinsurance on all Part B services with no annual out-of-pocket maximum — meaning a serious illness or extended hospitalization could cost you tens of thousands of dollars. The Annual Enrollment Period (AEP), which runs October 15 through December 7 each year, allows you to switch between Medicare Advantage and Original Medicare, or change your Part D plan. The Medicare Open Enrollment Period (OEP), running January 1 through March 31, allows Medicare Advantage enrollees to switch to a different MA plan or return to Original Medicare once. Outside of these windows, your ability to change coverage depends on qualifying for a Special Enrollment Period (SEP) triggered by events like moving, losing employer coverage, or a plan leaving your area.

One practical step every beneficiary should take right now is to log into your My Medicare account at Medicare.gov and review your current plan's 2026 costs. Your plan's Annual Notice of Change (ANOC) — mailed each September — outlines every cost and coverage change taking effect January 1. If you didn't save that document, Medicare.gov's Plan Finder tool lets you compare your current plan against alternatives in your ZIP code. For Part D specifically, the tool calculates your estimated annual drug costs based on the medications you actually take, which is far more useful than comparing premiums alone. A plan with a $0 premium but high cost-sharing on your specific drugs may cost you far more than a plan with a $35 monthly premium that covers those same drugs at a lower tier.
