A patient turns 65 and signs up for Medicare. She assumes everything is covered. Then she gets a hospital bill for $1,736. She assumes that it is the only bill. Then she gets another bill for a doctor visit. Then another for a specialist. She has no idea how much she will pay in a given year. She has no idea that there is no annual limit on what she can spend out of pocket.
This confusion happens because Medicare is not one plan. It is multiple parts with different costs. Part A covers hospitals. Part B covers doctors and outpatient care. Part D covers prescriptions. Part C, or Medicare Advantage, bundles everything together with different rules entirely. Each part has its own premiums, deductibles, and coinsurance.
This guide breaks down every Medicare cost for 2026. It covers premiums, deductibles, coinsurance, and the critical difference between Original Medicare and Medicare Advantage out-of-pocket limits.
Original Medicare vs. Medicare Advantage – A Critical Distinction
Before looking at any numbers, providers must understand one key difference between Original Medicare and Medicare Advantage. This difference affects everything about patient costs and billing.
- Original Medicare (Parts A and B) has no out-of-pocket maximum. A patient can pay deductibles and coinsurance all year with no stop. There is no cap. A patient with a serious illness could pay thousands of dollars in 20 percent coinsurance with no limit.
- Medicare Advantage (Part C) does have an out-of-pocket maximum. Private insurance companies administer these plans. Once a patient reaches the MOOP, the plan pays 100 percent of covered costs for the rest of the year. In 2026, the maximum allowed out-of-pocket limit for in-network services is $9,250.
This distinction matters for billing. A Medicare Advantage patient who hits the MOOP should have no additional cost-sharing. An Original Medicare patient has no such protection. Providers must know which type of coverage each patient has.
Medicare Part A Costs – Hospital Insurance
Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Most beneficiaries pay no premium for Part A because they paid Medicare taxes for at least 10 years (40 quarters) while working.
Part A Premiums 2026
| Work Credits | Years Worked | 2026 Monthly Premium |
| 40 or more quarters | 10+ years | $0 |
| 30 to 39 quarters | 7.5 to 10 years | $311 |
| Fewer than 30 quarters | Less than 7.5 years | $565 |
Approximately 99 percent of Medicare beneficiaries pay no Part A premium because they have at least 40 quarters of Medicare-covered employment.
Part A Deductible and Coinsurance 2026
Part A uses a benefit period, not a calendar year. A benefit period starts the day a patient is admitted as an inpatient. It ends when the patient has not received any inpatient hospital or skilled nursing care for 60 consecutive days. A patient can have multiple benefit periods in a single year. Each new benefit period triggers a new deductible.
| Service | What the Patient Pays in 2026 |
| Inpatient hospital deductible (Days 1-60 per benefit period) | $1,736 |
| Days 61-90 of hospitalization | $434 per day |
| Days 91-150 (lifetime reserve days) | $868 per day |
| After day 150 | All costs |
| Skilled nursing facility days 21-100 per benefit period | $217 per day |
Lifetime reserve days are limited to 60 days total. They do not renew each year or with a new benefit period. Once used, they are gone.
Who Buys Part A?
Most beneficiaries do not buy Part A because they qualify for premium-free coverage. The people who pay for Part A are:
- Individuals who did not work long enough to earn 40 quarters of coverage
- Certain individuals with disabilities who have exhausted other entitlements
- People who voluntarily enroll in Part A when they do not qualify for premium-free coverage
Anyone who buys Part A must also enroll in Part B and pay the Part B premium .
Medicare Part B Costs – Medical Insurance
Part B covers physician services, outpatient hospital care, durable medical equipment, laboratory tests, preventive services, and many other medical services not covered by Part A.
Part B Standard Premium 2026
The standard monthly Part B premium for 2026 is $202.90 .
This is an increase of $17.90 from $185.00 in 2025 .
Part B Income-Related Monthly Adjustment Amount (IRMAA)
Beneficiaries with higher incomes pay higher Part B premiums. The income thresholds for 2026 remain unchanged from 2025. Approximately 8 percent of Medicare beneficiaries pay these higher premiums.
| Individual Tax Return Income | Joint Tax Return Income | IRMAA | Total Monthly Premium |
| ≤ $109,000 | ≤ $218,000 | $0 | $202.90 |
| > $109,000 to ≤ $137,000 | > $218,000 to ≤ $274,000 | $81.20 | $284.10 |
| > $137,000 to ≤ $171,000 | > $274,000 to ≤ $342,000 | $202.90 | $405.80 |
| > $171,000 to ≤ $205,000 | > $342,000 to ≤ $410,000 | $324.60 | $527.50 |
| > $205,000 to < $500,000 | > $410,000 to < $750,000 | $446.30 | $649.20 |
| ≥ $500,000 | ≥ $750,000 | $487.00 | $689.90 |
Part B Deductible and Coinsurance 2026
| Cost Type | 2026 Amount |
| Annual deductible | $283 |
| Coinsurance after deductible | 20% of Medicare-approved amount |
The Part B deductible increased by $26 from $257 in 2025.
Once a patient pays the $283 deductible, they pay 20 percent of the Medicare-approved amount for most Part B services. This includes doctor visits, outpatient therapy, durable medical equipment, and many other services.
Part B Late Enrollment Penalty
Beneficiaries who do not sign up for Part B when first eligible (usually at age 65) may pay a penalty. The penalty is 10 percent for each full 12-month period the beneficiary could have had Part B but did not take it. The penalty lasts for as long as the beneficiary has Part B.
Medicare Part C (Medicare Advantage) Costs
Medicare Advantage plans are private insurance plans that contract with Medicare to provide Part A and Part B benefits. Most also include Part D prescription drug coverage .
Part C Premiums 2026
The average monthly premium for a Medicare Advantage plan in 2026 is $14 . However, premiums vary significantly by plan, insurer, and county. Some plans have $0 premiums. Others charge more.
Part C Out-of-Pocket Maximum 2026
This is the most important number for Medicare Advantage. In 2026, the maximum out-of-pocket limit for in-network services is $9,250.
This limit applies only to Part A and Part B covered services. It does not include:
- Part D prescription drug costs
- Supplemental benefits like dental or hearing
- Out-of-network services (plans may have separate, higher limits)
Once a patient reaches the plan’s MOOP, the plan pays 100 percent of covered costs for the rest of the year.
Part C Deductibles and Other Costs
Medicare Advantage plan deductibles vary by plan. There is no standard deductible. Providers must check each patient’s specific plan.
Key Changes for Medicare Advantage in 2026
- The maximum MOOP decreased from $9,350 in 2025 to $9,250 in 2026
- Fewer Medicare Advantage plans are available in 2026 (32 prescription drug plans, down from 34 in 2025)
- Prior authorization decisions must be made within 7 days (down from 14 days)
Medicare Part D Costs – Prescription Drug Coverage
Part D covers prescription drugs. Private insurance companies administer these plans. The Inflation Reduction Act of 2022 made significant changes to Part D costs starting in 2025 and continuing into 2026.
Part D Premiums 2026
| Cost Type | 2026 Amount |
| Average base premium | $38.99 per month |
| Maximum deductible | $615 per year |
Higher-income beneficiaries pay additional income-related adjustment amounts for Part D, similar to Part B.
Part D Out-of-Pocket Cap 2026
The most significant change to Part D is the out-of-pocket cap. In 2026, once a beneficiary spends $2,100 out of pocket on covered prescription drugs, they enter catastrophic coverage. At that point, they pay $0 for covered medications for the rest of the year.
This cap eliminates the previous coverage gap known as the “donut hole”.
Part D Inflation Reduction Act Benefits for 2026
- Insulin cap – Monthly out-of-pocket costs for insulin are capped at $35
- Vaccines – Part D recommended vaccines are available at $0 cost sharing
- Negotiated drug prices – Medicare negotiated lower prices for 10 high-cost medications including Eliquis, Jardiance, and Xarelto
- Medicare Prescription Payment Plan – Allows beneficiaries to make monthly payments toward prescription drug costs instead of paying all at once
Medigap (Medicare Supplement Insurance) Costs
Medigap is a private insurance plan that supplements Original Medicare. They pay some or all of the out-of-pocket costs that Original Medicare does not cover, such as deductibles, coinsurance, and copayments.
How Medigap Works
- Medigap only works with Original Medicare. A patient cannot have both a Medigap plan and a Medicare Advantage plan.
- Medigap plans are lettered A, B, C, D, F, G, K, L, M, and N. Each letter plan has a standardized set of benefits regardless of which insurance company sells it .
- Premiums vary by insurance company, plan type, and location. Companies set their own premiums.
2026 High-Deductible Medigap Limits
For high-deductible Medigap Plans F and G, the annual deductible for 2026 is $2,950. Once the patient pays this amount, the plan pays covered benefits for the rest of the year.
What Original Medicare Does Not Cover?
Providers and patients both need to understand what Original Medicare (Parts A and B) does not cover. These gaps explain why patients buy Medigap or Medicare Advantage.
Original Medicare does not cover:
- Most dental care, dentures
- Routine eye exams, glasses, contact lenses
- Hearing aids and exams for fitting them
- Long-term custodial care (assistance with bathing, dressing, eating)
- Most routine physical exams (the annual wellness visit is covered, but a full physical exam with all standard tests may not be)
- Most prescription drugs (Part D covers these separately)
- Care received outside the United States
Providers should document clearly when a service is not covered by Medicare. Patients need advance notice if they will be responsible for payment.
Help with Medicare Costs for Low-Income Beneficiaries
Beneficiaries with limited income and resources may qualify for help paying Medicare costs.
Medicare Savings Programs
State Medicaid programs offer Medicare Savings Programs that pay Part B premiums and may also pay Part A and Part B deductibles, coinsurance, and copayments.
Extra Help (Low-Income Subsidy) for Part D
The Low-Income Subsidy program, also called Extra Help, helps pay Part D premiums, deductibles, and coinsurance. In 2026, eligibility for Extra Help has expanded, allowing more individuals with limited income and resources to qualify .

Conclusion
Medicare costs for 2026 have increased across almost every category. The Part B standard premium rose nearly 10 percent to $202.90 per month. The Part A deductible increased by $60 to $1,736. The Part B deductible increased by $26 to $283.
But the most important number for patients is the out-of-pocket maximum. Original Medicare has none. A patient with a serious illness could pay unlimited 20 percent coinsurance. Medicare Advantage plans cap out-of-pocket costs at $9,250 for in-network services in 2026. Part D now caps out-of-pocket drug costs at $2,100.
Providers should know which type of coverage each patient has. A Medicare Advantage patient who hits the MOOP should owe nothing for covered services. An Original Medicare patient has no such protection. Document coverage type. Verify benefits. Help patients understand their costs before providing expensive services.
Frequently Asked Questions (FAQs)
What is the difference between Original Medicare and Medicare Advantage out-of-pocket costs?
Original Medicare (Parts A and B) has no out-of-pocket maximum. A patient can pay deductibles and 20 percent coinsurance all year with no stop. Medicare Advantage (Part C) does have an out-of-pocket maximum. In 2026, the maximum allowed out-of-pocket limit for in-network services is $9,250. Once a patient reaches that limit, the plan pays 100 percent of covered costs for the rest of the year.
How much is the Medicare Part B premium for 2026?
The standard monthly Part B premium for 2026 is $202.90. This is an increase of $17.90 from $185.00 in 2025. Higher-income beneficiaries pay more due to the Income-Related Monthly Adjustment Amount (IRMAA), with total monthly premiums ranging from $284.10 to $689.90 depending on income.
Does Original Medicare have a cap on what a patient pays out of pocket each year?
No. This is the biggest gap in Original Medicare. There is no annual out-of-pocket maximum. A patient with a serious illness requiring multiple hospital stays, surgeries, and specialist visits could pay thousands of dollars in deductibles and 20 percent coinsurance with no limit. This is why many patients buy Medigap policies or enroll in Medicare Advantage plans.
What is the Part A deductible for a hospital stay in 2026?
The Part A inpatient hospital deductible for 2026 is $1,736 per benefit period. A benefit period starts when a patient is admitted as an inpatient and ends when they have not received any inpatient hospital or skilled nursing care for 60 consecutive days. A patient can have multiple benefit periods in a single year, each triggering a new $1,736 deductible.
What is the out-of-pocket cap for Medicare Part D prescription drugs in 2026?
The Part D out-of-pocket cap for 2026 is $2,100. Once a beneficiary spends this amount on covered prescription drugs, they enter catastrophic coverage and pay $0 for covered medications for the rest of the year. This cap eliminates the previous coverage gap known as the “donut hole.” Insulin is also capped at $35 per month.
How much does a skilled nursing facility stay cost under Medicare Part A?
For days 1 through 20 of a skilled nursing facility stay, Medicare pays 100 percent and the patient pays $0. For days 21 through 100, the patient pays $217 per day in 2026. After day 100, the patient pays all costs. These coinsurance amounts apply per benefit period.
What is the late enrollment penalty for Medicare Part B?
Beneficiaries who do not sign up for Part B when first eligible (usually at age 65) may pay a penalty. The penalty is 10 percent for each full 12-month period the beneficiary could have had Part B but did not take it. The penalty lasts for as long as the beneficiary has Part B. For example, a beneficiary who delays enrollment for two years pays a 20 percent penalty on top of the standard premium permanently.
