Medicare Deductibles 2026: $1,736 Part A + $283 Part B

Key Takeaways

• Part A hospital deductible is $1,736 per benefit period in 2026, up $60 from 2025.
• Part B annual deductible is $283 in 2026, up $26 from 2025.
• Part D plans may charge up to $615 deductible in 2026; some plans charge $0.
• Medicare Advantage (Part C) deductibles vary by plan, some are $0.
• Medicare Savings Programs and Extra Help can cover deductibles for low-income enrollees.

Medicare deductibles jumped again for 2026, and the increases matter. The Part A hospital deductible climbed to $1,736 per benefit period. The Part B annual deductible rose to $283. Those two numbers alone can push a single hospital stay past $2,000 before Medicare pays a dime. Part D plans can charge up to $615, and Medicare Advantage plans set their own deductibles inside CMS-approved limits.

This guide breaks down every 2026 Medicare deductible using figures verified directly from the Centers for Medicare & Medicaid Services (CMS) fact sheet published November 14, 2025. You will see what changed from 2025, how the numbers stack against each other, and which federal programs can wipe your deductible to zero if you qualify.

What are the 2026 Medicare deductibles?

The 2026 Medicare deductibles are $1,736 for Part A (per benefit period), $283 for Part B (annual), and up to $615 for Part D (annual, plan-dependent). Medicare Advantage (Part C) sets its own deductible under CMS rules, ranging from $0 on many plans to a few hundred dollars.

Each part answers a different bill. Part A covers inpatient hospital, skilled nursing, hospice, and some home health. Part B covers outpatient doctor visits, preventive care, most tests, and durable medical equipment. Part D pays for retail prescription drugs. Part C bundles A and B, and usually D, through a private plan approved by CMS.

Here is a fast reference table with the year-over-year change baked in for the two amounts CMS sets by statutory formula.

Part	2025	2026	Change
Part A (per benefit period)	$1,676	$1,736	+$60
Part B (annual)	$257	$283	+$26

What is the Medicare Part A deductible for 2026?

The 2026 Medicare Part A deductible is $1,736 per benefit period, an increase of $60 over the 2025 figure of $1,676. Unlike Part B, this deductible is not annual. You can owe it more than once in the same calendar year if you start a new benefit period.

What counts as a benefit period?

A benefit period starts the day you are admitted as an inpatient at a hospital or skilled nursing facility. It ends after you have been out of any inpatient setting for 60 consecutive days. Get readmitted after that gap and a new benefit period begins, which means paying the $1,736 deductible again.

A patient hospitalized in January and again in May can pay the $1,736 Part A deductible twice, for $3,472 out of pocket, before Medicare coinsurance even kicks in. Most beneficiaries assume Part A works like private insurance with a single annual deductible. It does not, and that assumption is one of the most expensive mistakes seniors make with a medicare deductible in 2026.

Hospital coinsurance after the deductible

After you meet the deductible, Part A covers the first 60 hospital days at $0. Costs escalate quickly after that, as the CMS 2026 fact sheet lays out.

Hospital stay	Your daily cost (2026)
Days 1 to 60	$0 after $1,736 deductible
Days 61 to 90	$434 per day
Days 91 to 150 (lifetime reserve)	$868 per day
After day 150	All costs

Skilled Nursing Facility (SNF) coinsurance

Part A covers SNF stays after a qualifying 3-day inpatient hospital admission. Days 1 to 20 cost $0. Days 21 to 100 cost $217 per day in 2026, up from $209.50 in 2025. From day 101 forward, you pay everything.

For the full Part A premium rules, including the $311 and $565 monthly tiers for people without full work credits, see our companion guide on the Medicare Part A premium in 2026.

What is the Medicare Part B deductible for 2026?

The 2026 Medicare Part B deductible is $283 per year, up $26 from the 2025 figure of $257. It resets every January 1. Once you meet it, Part B pays 80% of the Medicare-approved amount for most services, and you owe the remaining 20% coinsurance for the rest of the year.

What does Part B cover?

Part B pays for outpatient care: doctor visits, lab work, X-rays, most preventive screenings, mental health visits, durable medical equipment, and Medicare-covered ambulance services. Some preventive services (the annual wellness visit, mammograms, and colonoscopies at approved intervals) bypass the deductible entirely and are covered at 100%.

The 20% coinsurance stack

Here is where many beneficiaries get hit with a surprise. After meeting the $283 deductible, you still owe 20% of the Medicare-approved amount forever. Original Medicare Part B has no annual out-of-pocket cap. A $30,000 chemotherapy course means $6,000 out of pocket unless you carry Medigap, Medicare Advantage, or Medicaid.

IRMAA and the deductible

The IRMAA surcharge affects Part B premiums, not the deductible. Single filers with 2024 modified adjusted gross income (MAGI) above $109,000 pay a higher monthly premium tier, but the $283 deductible is the same for every enrollee. For the full IRMAA breakdown by income bracket, see our Medicare Part B premium guide.

What is the Part D drug deductible cap in 2026?

The 2026 Part D deductible cap is $615, a regulatory ceiling set by CMS under the Inflation Reduction Act. Individual Part D plans may charge less. Many plans charge $0. What you actually pay depends on the plan you enroll in during Medicare Open Enrollment or a valid Special Enrollment Period.

How the Part D payment phases work

Part D uses a staged cost-sharing structure. In 2026 you move through these phases as your drug spending climbs across the calendar year.

• Deductible phase. You pay 100% until you hit your plan’s deductible, capped at $615.
• Initial coverage. You pay 25% coinsurance on covered generic and brand-name drugs.
• Catastrophic phase. Kicks in once your out-of-pocket drug spending reaches $2,100. You pay $0 for the rest of the calendar year.

The $2,100 catastrophic threshold is a hard annual cap on what Part D enrollees pay out of pocket for covered drugs. It is up from $2,000 in 2025. This cap was created by the Inflation Reduction Act and is one of the most significant changes to Medicare drug coverage in a generation.

Late enrollment penalty math

Miss your Part D enrollment window without other creditable coverage and CMS adds a permanent penalty: 1% of the national base beneficiary premium ($38.99 in 2026) times each full uncovered month. Fourteen uncovered months equals 14% of $38.99, or about $5.46 per month for life. The penalty is waived entirely if you qualify for Extra Help (LIS).

What about Medicare Advantage (Part C) deductibles?

Medicare Advantage (Part C) plans set their own deductibles under CMS rules. Each plan must cover everything Original Medicare covers, but the plan can rearrange how you pay. Many Medicare Advantage plans advertise $0 medical deductibles and $0 drug deductibles as a competitive selling point during Open Enrollment.

Two deductibles inside one plan

Most Medicare Advantage plans that include Part D coverage carry two separate deductibles. There is one for medical services (often $0 to a few hundred dollars) and one for prescriptions (also often $0, capped by the same $615 Part D ceiling). Read the Summary of Benefits carefully during Open Enrollment before you enroll.

The MOOP cap advantage

Unlike Original Medicare, every Medicare Advantage plan must include an annual out-of-pocket maximum (MOOP) for in-network Part A and Part B services. Once you hit that MOOP, the plan pays 100% of covered services for the rest of the year. That is a real financial ceiling Original Medicare alone does not provide, which is one reason enrollment in Medicare Advantage keeps climbing.

How have Medicare deductibles changed for 2026?

Medicare deductibles all increased for 2026. Part A rose $60 (3.6%), Part B rose $26 (10.1%), and the Part D catastrophic out-of-pocket cap rose $100 (5.0%). The Part B increase in percentage terms is the steepest of the three, tied to higher projected physician spending across the program.

What is driving the increases?

CMS bases Part A hospital deductibles on projected inpatient hospital costs. Part B deductibles are set to keep pace with projected Part B benefits spending per enrollee. Part D thresholds are indexed under Inflation Reduction Act formulas. All three follow statutory formulas, not policy discretion, which is why the numbers rise almost every year regardless of who is in the White House.

Historical multi-year pattern

We have tracked every CMS annual fact sheet for the past several years. The consistent pattern is single-digit percentage increases for Part A and Part B most years, with occasional larger jumps (like the 2022 Part B spike that was later partially reversed). Anyone building a Medicare cost forecast should assume 3% to 6% annual deductible growth as a baseline.

Can I deduct Medicare premiums or deductibles on my taxes?

Yes, if you itemize. The IRS treats Medicare premiums, deductibles, coinsurance, and copayments as qualified medical expenses under Internal Revenue Code Section 213. You can deduct the portion of your total medical expenses that exceeds 7.5% of your adjusted gross income (AGI), per IRS Publication 502.

How the 7.5% AGI threshold works

A retiree with $50,000 in AGI can only deduct medical expenses above $3,750 (7.5% of $50,000). If you spend $6,000 on Medicare-related costs in a year, only $2,250 is deductible, and only if you itemize on Schedule A rather than take the standard deduction. Many retirees no longer itemize post-TCJA, so this deduction is worth running the math on both ways.

Self-employed rule is different

If you have net self-employment income, you can deduct 100% of Medicare Part B, Part D, and Medigap premiums above the line on Schedule 1, without the 7.5% floor and without itemizing. Deductibles themselves still fall under the itemized medical expense rules. This above-the-line premium deduction is one of the most under-used tax breaks for older self-employed workers.

How can you lower your Medicare deductible costs?

Four federal programs can eliminate or reduce a medicare deductible in 2026 for low- and moderate-income enrollees: Medicare Savings Programs (MSPs), Extra Help (LIS), full Medicaid dual-eligibility, and Medigap Plans G or F. Each has its own income and asset test set at the federal or state level.

Medicare Savings Programs (MSPs)

MSPs are state-administered programs that use federal Medicaid dollars to pay Medicare Part A and Part B premiums, deductibles, coinsurance, and copayments for people who qualify. The most generous tier, Qualified Medicare Beneficiary (QMB), covers the full $1,736 Part A deductible and the full $283 Part B deductible. Two lower tiers (SLMB and QI) cover just the Part B premium.

Read our step-by-step Medicare Savings Programs eligibility guide for current income limits and how to apply through your state Medicaid agency.

Extra Help for Part D

Extra Help (Low Income Subsidy) waives your Part D deductible entirely and caps generic drug copays at a few dollars. In 2026, income limits are $23,475 for singles and $31,725 for married couples, with resource caps of $18,090 and $36,100 respectively. SSA estimates the benefit is worth about $5,700 per year per enrollee.

Medigap plans that cover Part A and B deductibles

Medigap Plan G covers the Part A deductible and hospital coinsurance in full but leaves you responsible for the $283 Part B deductible each year. Plan F, only available to those first eligible for Medicare before January 1, 2020, covers the Part B deductible too. Monthly Medigap premiums vary widely by state and issue age.

Full Medicaid dual-eligibility

People who qualify for both Medicare and full-benefit Medicaid have their Part A and B deductibles paid by Medicaid, plus most coinsurance. Income and asset limits are stricter than MSPs and vary by state. Our Medicaid hub explains state-by-state eligibility. If you are receiving SSDI and Medicare, you may qualify sooner than you expect.

What are the biggest mistakes people make with Medicare deductibles?

The most costly Medicare deductible mistakes come from assuming Part A works like private health insurance. In our reader mailbag, we see four errors on repeat: treating Part A as annual, skipping the MSP application, miscalculating the Part D late penalty, and failing to plan for dual benefit periods in a bad-health year.

Thinking Part A resets on January 1

Part A does not reset annually. It resets by benefit period. Two hospitalizations separated by more than 60 days each trigger a fresh $1,736 deductible. A patient with congestive heart failure or COPD could easily hit that twice in one calendar year, and their financial planning needs to reflect that reality.

Not applying for an MSP because “I probably don’t qualify”

A 2025 study in JAMA Network Open (Kotb et al) found MSP take-up among eligible beneficiaries varies widely by state, from a low of 41.5% in Ohio, meaning millions of eligible individuals never enroll. Income limits are more generous than most people assume, and asset tests exclude your primary home and one vehicle. If your monthly income is under about $1,700 as a single filer, submit the application through your state Medicaid office. The worst outcome is a denial letter.

Miscalculating the Part D late enrollment penalty

The Part D penalty is 1% of the national base premium ($38.99 in 2026) per uncovered month, added to your monthly premium permanently. Twenty-four uncovered months equals 24% of $38.99, or about $9.36 per month for life. Delay does not save money. It just shifts cost from today to every month you are on Medicare.

Not planning for dual benefit periods

People with serious chronic conditions should budget for the possibility of two Part A deductibles in a single year. That is $3,472 out of pocket for hospital admissions alone, plus SNF coinsurance if applicable. An emergency fund of at least $4,000 to $5,000 is prudent if you lack Medigap coverage or QMB support.

How do you check your remaining Medicare deductible?

You have three ways to see how much of your 2026 Medicare deductible you have already met: your quarterly Medicare Summary Notice (MSN), your MyMedicare.gov account, or your plan’s Explanation of Benefits (EOB) if you are enrolled in Medicare Advantage or a Part D plan.

MyMedicare.gov account

Log in at MyMedicare.gov to see real-time claims, deductible status, and preventive services usage. This is the fastest and most accurate source. You can also download detailed claim records for tax preparation and share access with a trusted family member if you set up authorized representative permissions.

Medicare Summary Notice

Original Medicare mails an MSN every three months. It lists services billed, what Medicare paid, what you may owe, and how much of your Part B deductible remains for the year. Keep every notice for at least three years for potential Medicare Secondary Payer issues or supplemental insurance claim reconciliation.

When are the 2027 Medicare deductibles announced?

CMS traditionally announces the following year’s Medicare Part A and B premiums and deductibles in mid-November. The 2026 fact sheet was published November 14, 2025. Expect the 2027 announcement in the second week of November 2026, followed by the 2027 Part D national base beneficiary premium in late July or early August 2026.

Once released, the 2027 numbers take effect January 1, 2027. Part B enrollees will see the new deductible on their first 2027 claim of the year. Part A applies to any new inpatient benefit period beginning on or after January 1, 2027.
