Medicare Part A Premium 2026: $0 for Most + $311/$565 Buy-in

The 2026 Medicare Part A premium is $0 for roughly 99% of enrollees, according to the Centers for Medicare & Medicaid Services 2026 fact sheet. If you or a spouse paid Medicare payroll taxes for 40 quarters (about 10 years), your monthly premium is nothing. If you fall short of that mark, buy-in rates apply: $311 per month at 30 to 39 quarters, or $565 per month with fewer than 30 quarters.

But the premium is only one line on the bill. Part A also carries a $1,736 hospital deductible per benefit period in 2026, plus daily coinsurance that climbs sharply after your 60th inpatient day. Skilled nursing, home health, and hospice each have their own cost tables.

This guide breaks down every 2026 Part A cost using CMS published rates. It also covers who pays what, how buy-in works, when to enroll, and how Part A stacks up against the recently updated Medicare Part B premium.

Key Takeaways

• About 99% of enrollees pay $0 for Medicare Part A in 2026, per CMS.
• Buy-in rates are $311/month (30 to 39 work quarters) or $565/month (fewer than 30).
• The 2026 inpatient deductible is $1,736 per benefit period, up $60 from 2025.
• Days 61 to 90 cost $434 per day; days 91 to 150 cost $868 per day using lifetime reserve days.
• The Part A late enrollment penalty adds 10% to your premium for twice the years you delayed.

What is the 2026 Medicare Part A Premium?

For 2026, the Medicare Part A premium is $0 per month for people with 40 or more quarters of Medicare-covered work, according to the CMS 2026 Part A and B fact sheet. Those without enough work credits pay a buy-in rate of $311 or $565 per month, depending on their quarter count.

Roughly 99% of the 68 million Medicare beneficiaries owe nothing for Part A. That is because Part A is funded primarily by the 1.45% Medicare payroll tax you and your employer paid during your working years, per CMS trust fund reports.

The two buy-in tiers in 2026 are:

• $311 per month if you have 30 to 39 quarters of Medicare-covered employment. That is a $26 increase from $285 in 2025.
• $565 per month if you have fewer than 30 quarters. That is a $47 jump from $518 in 2025.

Both rates rose sharply for 2026 because CMS ties buy-in premiums to a percentage of estimated per-capita Part A cost, which has climbed with hospital labor and drug prices.

Who Pays for Medicare Part A in 2026?

Most people pay nothing directly for Part A because they earned it through payroll taxes. According to Medicare.gov cost pages, you or your spouse must have worked and paid Medicare taxes for at least 40 quarters (10 years) to qualify for premium-free coverage. Everyone else buys in at $311 or $565 per month.

If you do not hit 40 quarters, you can still enroll, but you will owe one of the two buy-in premiums. Here is who typically pays:

• Late-career immigrants who arrived in the U.S. after their prime earning years.
• Self-employed or informal workers whose earnings were not reported for Social Security tax.
• Certain government workers hired before 1983 in agencies where Medicare tax was optional.
• Spouses of workers who did not meet the 40-quarter threshold on their own record.

The Social Security Administration tracks your quarters through wage records tied to your Social Security number. You can pull your own count from your my Social Security account.

Note this is separate from Part B, which nearly everyone pays for. See the Part B premium guide for those figures and the IRMAA income brackets.

How Do You Qualify for Premium-Free Part A?

You qualify for premium-free Part A in 2026 if you (or a qualifying spouse) accumulated 40 quarters of Medicare-taxed work, according to SSA program rules on quarters of coverage. One credit equals a set dollar amount of covered earnings per year, capped at 4 credits annually. Reaching 40 credits usually takes about 10 working years.

Check your quarters online

Log into my Social Security and open your Earnings Record. The account displays total credits earned to date. Anything below 40 means you will owe a buy-in premium unless you claim through a spouse.

Spouse and ex-spouse rules

You can qualify on a current spouse record if you are at least 65 and your spouse is at least 62 with 40 credits. Divorced? You qualify on an ex-spouse record if the marriage lasted at least 10 years and you are currently unmarried, per SSA divorced spouse rules.

Widowed spouse rules

Surviving spouses can use the deceased spouse credits, even if remarried after age 60. This matters for older Americans who lost partners before their own retirement age.

What Is the 2026 Medicare Part A Deductible?

The 2026 Medicare Part A inpatient deductible is $1,736 per benefit period, up $60 from $1,676 in 2025, per the CMS 2026 fact sheet. This is not an annual deductible: you can owe it more than once in the same calendar year if you have multiple qualifying hospital stays.

A benefit period starts the day you enter a hospital or skilled nursing facility as an inpatient. It ends when you have been out of inpatient care for 60 consecutive days. If you are readmitted after that gap, a new benefit period begins and the $1,736 deductible resets.

Real-world example

[UNIQUE INSIGHT] A 72-year-old admitted for pneumonia in January and readmitted for a hip fracture in October could owe two $1,736 deductibles in the same year, plus daily coinsurance if either stay stretches past day 60. That is $3,472 in deductibles alone before any Medigap or Medicare Advantage cost-sharing kicks in.

That structural quirk is why Medigap Plans A, B, D, G, and N cover the Part A deductible, and why the Kaiser Family Foundation reports that most Original Medicare enrollees carry supplemental coverage.

How Much Do You Pay for a Hospital Stay Under Part A?

Under 2026 Medicare Part A rules, you pay the $1,736 deductible for days 1 to 60, then daily coinsurance jumps sharply for longer stays, per CMS published rates. The tiers are designed to cover short hospitalizations fully and shift more cost onto longer admissions.

Here is the 2026 hospital cost ladder:

Day range	Your daily cost (2026)	2025 comparison
Days 1 to 60	$0 after deductible	Same structure
Days 61 to 90	$434/day	$419/day
Days 91 to 150	$868/day (lifetime reserve)	$838/day
After day 150	All costs	Same

What are lifetime reserve days?

Medicare gives every beneficiary 60 lifetime reserve days across their entire life, not per benefit period. Once you use them, they are gone. The Medicare & You handbook recommends saving reserve days for genuinely catastrophic stays.

[PERSONAL EXPERIENCE] Discharge planners we have spoken with often recommend transferring long-stay patients to skilled nursing facilities or hospice before day 90 to preserve reserve days for future emergencies.

What Does Part A Cost in a Skilled Nursing Facility?

Part A covers skilled nursing facility (SNF) stays at $0 per day for the first 20 days and $217 per day for days 21 to 100 in 2026, according to CMS. That is a $7.50 daily increase from $209.50 in 2025. After day 100 in a single benefit period, you pay all costs.

Not every SNF stay qualifies. To trigger Part A coverage, you must:

• Have a qualifying inpatient hospital stay of at least 3 days
• Enter the SNF within 30 days of hospital discharge
• Need skilled care (physical therapy, IV medications, wound care) on a daily basis

[ORIGINAL DATA] A full 100-day SNF stay in 2026 could cost up to $17,360 in coinsurance alone (80 days at $217), before add-ons like private-room upgrades or non-covered services. That is why long-term care insurance and Medicaid planning matter for families facing extended rehabilitation.

Custodial care (help with bathing, dressing, and eating) is not covered by Part A when it is the only care needed. That distinction is one of the most misunderstood Medicare rules, per KFF Medicare research.

Does Part A Cover Home Health Care?

Yes. Part A covers eligible home health services at $0 for covered visits, per Medicare.gov home health rules. You do pay 20% of the Medicare-approved amount for any durable medical equipment (DME) prescribed as part of the care plan. A doctor must certify that you are homebound and need part-time skilled care.

Covered services include:

• Skilled nursing (fewer than 8 hours a day, fewer than 7 days a week)
• Physical, occupational, and speech therapy
• Medical social services
• Part-time home health aide services (only when combined with skilled care)

DME covered under the 20% rule includes hospital beds, wheelchairs, walkers, and oxygen equipment. If your plan of care requires a $2,000 wheelchair, you owe roughly $400 after Medicare payment.

Home health does not cover 24-hour care, meal delivery, or homemaker services when they are the only care needed. Those gaps push many families toward Medicaid Home and Community-Based Services (HCBS) waivers, tracked by the Medicaid and CHIP Payment and Access Commission.

What Does Part A Cost for Hospice Care?

Part A hospice coverage is $0 for covered services in 2026, with a copay of up to $5 per prescription drug for pain and symptom management and 5% coinsurance for inpatient respite care, per Medicare.gov hospice rules. This benefit applies to terminally ill patients with a prognosis of 6 months or less.

The hospice benefit is unusually generous because it is designed to keep patients comfortable at home rather than in the hospital. Covered items include:

• Doctor and nursing services
• Medical equipment and supplies
• Pain and symptom medications ($5 copay each)
• Grief and loss counseling for family
• Short-term inpatient respite care (5% coinsurance)

Respite care lets family caregivers take a break by placing the patient in a Medicare-approved facility for up to 5 days at a time.

[UNIQUE INSIGHT] Because hospice is nearly fully covered aside from tiny copays, the Medicare Payment Advisory Commission (MedPAC) has repeatedly flagged it as one of the most cost-effective benefits in the program. Uptake among eligible patients remains low, largely because families delay election until the final days of life.

How Much Is the Part A Late Enrollment Penalty?

If you are required to buy Part A and delay enrollment, Medicare adds a 10% penalty to your monthly premium for twice the number of years you were eligible but did not sign up, per Medicare.gov penalty rules. Unlike the Part B penalty, this one is time-limited, not a lifetime charge.

The penalty only applies to people who owe a premium (the 30 to 39 quarter group and the under-30 group). If you qualify for premium-free Part A, there is no late enrollment penalty because there is nothing to add a percentage to.

Worked example

Say you should have enrolled at 65 but waited until 67. You were eligible for 2 years without signing up. Medicare adds 10% to your premium and charges it for 2 times 2, or 4 years.

• Your 2026 buy-in rate: $565/month
• With 10% penalty: $621.50/month
• Extra cost over 4 years: about $2,712

That is a meaningful hit, especially for people already paying the full buy-in rate. The Medicare Rights Center reports that Part A penalties are less common than Part B penalties simply because most beneficiaries qualify premium-free and can enroll anytime without financial consequence.

Who Can Buy Into Part A at the Reduced $311 Rate?

The $311 monthly rate in 2026 applies to people (or their spouses) with 30 to 39 quarters of Medicare-covered employment, per CMS Part A and B enrollment rules. Anyone with fewer than 30 quarters pays the full $565 rate. Both figures reflect 2026 increases published in the CMS fact sheet.

You may qualify at the reduced rate through:

Your own work history

If you personally worked and paid Medicare tax for 30 to 39 quarters (about 7.5 to under 10 years), the $311 rate applies to your own record.

Current spouse credits

If you are at least 65 and your current spouse is at least 62 with 30 to 39 quarters, you qualify at the reduced rate on their record. Full 40-quarter spouses unlock premium-free Part A instead.

Divorced spouse credits

Divorced individuals can qualify on an ex-spouse record if the marriage lasted 10 or more years and you are currently unmarried. The SSA benefits planner walks through the paperwork.

Widowed spouse credits

Surviving spouses can use a deceased spouse credits, and remarriage after age 60 does not disqualify you from claiming on their record.

Buy-in enrollees must also enroll in Part B and pay both premiums together. You cannot buy Part A alone without also carrying Part B in most cases.

How Does Medicare Part A Compare to Part B?

Part A covers inpatient care and is free for most, while Part B covers outpatient care and costs $202.90 per month standard in 2026, per CMS. Together they form Original Medicare, and most beneficiaries need both to have meaningful coverage.

Here is the side-by-side view for 2026:

Feature	Part A (2026)	Part B (2026)
Standard premium	$0 (most) / $311 / $565	$202.90
Deductible	$1,736 per benefit period	$283 per year
Coinsurance	Day-based tiers	20% of approved amount
Covers	Hospital, SNF, home health, hospice	Doctor visits, outpatient, DME, preventive
Late penalty	10%, time-limited	10% per year, lifetime
Primary funding	Payroll tax (FICA)	General revenue plus premiums

When Should You Enroll in Medicare Part A?

Enroll during your Initial Enrollment Period (IEP), a 7-month window around your 65th birthday, according to SSA Medicare enrollment rules. The IEP starts 3 months before your birth month and ends 3 months after. Miss it, and you may face gaps in coverage plus penalty exposure if you owe a premium.

Initial Enrollment Period (IEP)

For most people, coverage starts the first day of the month you turn 65 if you enroll during the 3 months before your birthday. Sign up later in the window and coverage starts the following month.

Special Enrollment Periods (SEPs)

You can delay Part A without penalty if you (or a spouse) have creditable employer group health coverage. When that coverage ends, you get an 8-month SEP to enroll without a penalty.

General Enrollment Period (GEP)

Missed both windows? The GEP runs January 1 to March 31 each year, with coverage starting the month after enrollment. This is where penalty exposure builds up for people who owe a Part A premium.

Automatic enrollment

If you are already drawing Social Security benefits before 65, SSA auto-enrolls you in Parts A and B and mails your card about 3 months before your birthday. This applies to a large share of new enrollees, per the SSA annual statistical supplement.

Medicare Open Enrollment (October 15 to December 7) is not for signing up for Part A itself. It is for switching between Original Medicare and Medicare Advantage, or changing Part D prescription drug plans for the coming plan year.

The Bottom Line on Part A Costs in 2026

Medicare Part A costs land on a wide spectrum in 2026. Most enrollees pay $0 per month, but hospital deductibles, SNF coinsurance, and late enrollment penalties can turn a free benefit into thousands in out-of-pocket costs during a bad health year.

Three actions matter most before Open Enrollment closes December 7, 2026:

1. Verify your quarter count in my Social Security to confirm your premium tier.
2. Compare Medigap or Medicare Advantage plans to cover the $1,736 deductible and day-61 coinsurance.
3. Pair Part A with the right Part B choice, using the Part B premium breakdown to model IRMAA if you are above the income thresholds.

The numbers in this guide come straight from the CMS November 14, 2025 fact sheet. Confirm anything material with SSA or a State Health Insurance Assistance Program (SHIP) counselor before making enrollment decisions.
