Medicare Costs in 2026: Premiums, Deductibles and Coinsurance

Medicare covers a lot, but it is not free. Depending on the coverage you have, you can owe a monthly premium, a deductible before coverage starts, and a share of each bill afterward. The amounts are set by law and formula, and they change every January.

This guide walks through what Original Medicare costs in 2026, using the figures the Centers for Medicare & Medicaid Services (CMS) released on November 14, 2025, and the cost tables on Medicare.gov, plus the costs that vary by plan.

Four words that explain every bill

A premium is what you pay each month for coverage, whether or not you use it. A deductible is what you pay before Medicare starts to pay. Coinsurance is your percentage share of a covered service, and a copayment is a fixed dollar amount.

Original Medicare (Part A and Part B) has no yearly cap on what you pay out of pocket. Medicare.gov's 2026 cost page says there is no yearly limit unless you have supplemental coverage, such as a Medicare Supplement Insurance (Medigap) policy, or join a Medicare Advantage Plan.

Part A (hospital insurance) in 2026

Most people pay no Part A premium. Medicare.gov's 2026 cost page explains that the premium is $0 for most people because they or a spouse paid Medicare taxes long enough while working, generally at least 10 years. CMS's 2026 fact sheet puts it this way: approximately 99% of Medicare beneficiaries do not have a Part A premium.

If you do not qualify for premium-free Part A, you may be able to buy it. For 2026, Medicare.gov lists a monthly Part A premium of either $311 or $565, depending on how long you or your spouse worked and paid Medicare taxes. Per CMS's 2026 fact sheet, the $311 rate is for people with at least 30 quarters of coverage (or a spouse who has them); $565 is for certain people with fewer.

The Part A deductible works differently from most deductibles. For 2026, Medicare.gov lists a deductible of $1,736 for each inpatient hospital benefit period, not each year. A benefit period starts the day you are admitted as an inpatient in a hospital or skilled nursing facility and ends when you have gone 60 days in a row without inpatient hospital care or skilled care in a facility. There is no limit to the number of benefit periods, so you can pay the deductible more than once in a year.

For an inpatient hospital stay in a single benefit period, Medicare.gov's 2026 cost page lists:

• Days 1 to 60: $0 per day after the 2026 deductible of $1,736, per Medicare.gov.
• Days 61 to 90: $434 per day in 2026, per Medicare.gov.
• Days 91 to 150: $868 per day in 2026, per Medicare.gov, while you use your 60 lifetime reserve days.
• After day 150: you pay all costs.

For a skilled nursing facility stay, the same 2026 page lists $0 per day for days 1 to 20, $217 per day for days 21 to 100, and all costs after day 100. Covered home health and hospice services are $0, though Medicare.gov's 2026 page lists a hospice copayment of up to $5 for each prescription for pain relief and symptom control at home.

Part B (medical insurance) in 2026

For 2026, Medicare.gov lists the standard Part B premium as $202.90 a month, and CMS's 2026 fact sheet notes that this is an increase of $17.90 from $185.00 in 2025. You pay it every month even if you use no Part B services. People with higher incomes pay more; our guide to IRMAA explains how that works.

For 2026, Medicare.gov lists a Part B deductible of $283, paid once a year.

After the deductible, you usually pay 20% of the Medicare-approved amount for each covered service or item, as long as your doctor or other provider accepts assignment (agrees to take the Medicare-approved amount as full payment). Details from Medicare.gov's 2026 cost page:

• Covered clinical laboratory services and covered home health services are $0 in 2026.
• Durable medical equipment such as walkers and wheelchairs is 20% of the Medicare-approved amount in 2026.
• In a hospital outpatient setting, you also pay the hospital a copayment for most services, which Medicare.gov says in most cases won't be more than the Part A hospital stay deductible. That means the same service can cost more in a hospital outpatient department than in a doctor's office.

Costs that vary by plan

Some costs have no national number because Medicare-approved private plans set them.

Medicare Advantage Plans (Part C): Medicare.gov's 2026 page says premiums, deductibles, copayments and coinsurance vary by plan and can change each year. You must keep paying your Part B premium to stay in the plan. Each plan also has a yearly out-of-pocket limit; once you reach it, the plan pays 100% of covered health services for the rest of the calendar year.

Part D drug coverage: premiums, deductibles and copayments vary by plan and pharmacy. For 2026, Medicare.gov lists a Part D out-of-pocket limit of $2,100, which includes your deductible, your out-of-pocket spending and certain payments made on your behalf, such as through Extra Help. Higher-income enrollees also pay an income-related amount on top of the plan premium.

Medigap: Medicare.gov's 2026 page says premiums vary based on the policy you buy, where you live and other factors. You must have Part B and keep paying its premium to keep a Medigap policy.

A hypothetical year, step by step

For example, imagine a person with Original Medicare only, who pays the standard Part B premium and has premium-free Part A. Every figure below is from Medicare.gov's 2026 cost page:

1. Part B premiums: 12 months at Medicare.gov's 2026 standard premium of $202.90 comes to $2,434.80 for 2026.
2. A few doctor visits: the first $283 of covered Part B services goes to Medicare.gov's 2026 Part B deductible, then the person pays about 20% of each Medicare-approved amount.
3. A five-day hospital stay in March: one Part A deductible, $1,736 in 2026 per Medicare.gov, covers the inpatient days, and the person also pays 20% of the Medicare-approved amount for most doctor services during the stay.
4. A second admission in October, after more than 60 days in a row without inpatient or skilled nursing care: that starts a new benefit period, so another $1,736 deductible applies in 2026, per Medicare.gov.

Nothing in Original Medicare caps that total, so compare the full yearly cost of any coverage, not just the premium.

When the numbers change, and where to get help

CMS sets new Part A and Part B amounts each year, and it released the 2026 figures on November 14, 2025. Plan premiums and benefits can also change each year. Before budgeting for next year, check Medicare.gov's costs page and your plans' notices.

If the costs are hard to manage, there is help. Medicare Savings Programs, run by states, can pay Part B premiums and sometimes deductibles and coinsurance. Extra Help lowers Part D costs for people with limited income and resources. Your SHIP can help you check whether you qualify, at no cost. Be wary of anyone who calls offering to lower your Medicare costs in exchange for your Medicare number; Medicare.gov says Medicare will never call you to sell you anything.
