Medicare Deductibles and Costs Explained (2026)

Updated June 4, 20267 min readReviewed against medicare.gov

A Medicare deductible is the amount you pay out of pocket for covered services before Medicare starts paying its share. In 2026, the Part A hospital deductible is $1,736 per benefit period (not per year), and the Part B deductible is $283 per calendar year. After you meet the Part B deductible, you generally pay 20% coinsurance for most services. These deductibles are separate from your monthly premiums, copays, and coinsurance — each is a different kind of cost.

Deductible vs. premium, copay, and coinsurance

These four words are easy to mix up, but they mean different things. Knowing the difference helps you understand exactly when and why you owe money.

A deductible is the amount you pay for covered services before Medicare begins to pay its share. A premium is the fixed amount you pay each month just to keep your coverage, whether or not you use any care. A copay is a flat dollar amount for a specific service (more common in Medicare Advantage and Part D drug plans). Coinsurance is a percentage of the cost you pay after the deductible is met.

Premium — paid monthly to have coverage (Parts A, B, C, and D may each have one).
Deductible — paid first, before Medicare pays, on covered services.
Coinsurance — your share as a percentage after the deductible (often 20% under Part B).
Copay — a flat fee per visit or prescription, set by your plan.

2026 Part A deductible and the benefit-period reset

Part A covers inpatient hospital stays, skilled nursing care, and some other services. In 2026 the Part A deductible is $1,736 — but it works differently from most deductibles because it applies per benefit period, not per calendar year.

A benefit period begins the day you are admitted as an inpatient and ends after you have been out of a hospital or skilled nursing facility for 60 days in a row. If you are admitted again after that 60-day gap, a new benefit period starts and you pay the deductible again. This means you could pay the Part A deductible more than once in a single year if you have separate hospital stays.

2026 Part A deductible: $1,736 per benefit period.
Inpatient hospital coinsurance, days 61-90: $434 per day.
Lifetime reserve days (after day 90): $868 per day.
Skilled nursing facility coinsurance, days 21-100: $217 per day.
Most people pay $0 for the Part A premium if they have 40+ quarters of Medicare-covered work; otherwise it is $311/mo (30-39 quarters) or $565/mo (under 30 quarters).

2026 Part B deductible, premium, and coinsurance

Part B covers doctor visits, outpatient care, lab tests, and durable medical equipment. Unlike Part A, the Part B deductible is annual: in 2026 you pay $283 once per calendar year before Medicare begins paying.

After you meet the $283 deductible, you generally pay 20% of the Medicare-approved amount for most covered services, and Medicare pays the other 80%. The standard Part B monthly premium in 2026 is $202.90, though higher earners pay more (see the IRMAA section below).

2026 standard Part B premium: $202.90 per month.
After the deductible: you pay 20% coinsurance for most services.

Part D drug costs: deductibles and the 2026 out-of-pocket cap

Part D covers prescription drugs and is sold by private insurers, so costs vary from plan to plan. Each Part D plan sets its own deductible up to a federal maximum, and some plans have a $0 deductible. Always check the specific plan's details.

For 2026, there is a $2,100 cap on what you pay out of pocket for covered prescription drugs. Once your out-of-pocket drug spending reaches $2,100 in the year, you pay nothing more for covered drugs for the rest of that year. This catastrophic protection limits how much any one year can cost you for medications.

Each Part D plan sets its own deductible up to the annual federal maximum; some plans have $0.
2026 out-of-pocket cap for covered drugs: $2,100 per year.
The Part D national base beneficiary premium for 2026 is $38.99/mo (used to calculate the late penalty).

Late penalties and IRMAA (income-related surcharges)

Two things can permanently raise your monthly Medicare costs: signing up late and having a higher income.

If you do not enroll in Part B when first eligible and do not have other qualifying coverage, the Part B premium goes up 10% for each full 12-month period you could have had it but did not — and that penalty lasts for as long as you have Part B. The Part D late penalty is 1% of the $38.99 national base premium for each full month you went without drug coverage, rounded to the nearest $0.10, and it is added to your premium for life.

IRMAA is an income-related surcharge added to your Part B and Part D premiums if your income is above set thresholds. For 2026, surcharges begin when your 2024 modified adjusted gross income (MAGI) is above $109,000 for a single filer or $218,000 for a married couple filing jointly.

Part B late penalty: +10% of the premium per full 12 months eligible but not enrolled, for life.
Part D late penalty: 1% of $38.99 × full uncovered months, rounded to the nearest $0.10, for life.
IRMAA thresholds (2026): above $109,000 single / $218,000 joint MAGI.
With IRMAA, the 2026 total Part B premium ranges from $284.10 to $689.90/mo.
With IRMAA, the 2026 Part D surcharge ranges from $14.50 to $91.00/mo, added on top of your plan premium.

Medicare Advantage, Medigap, and lowering your costs

Your deductibles depend on how you get your Medicare. Medicare Advantage (Part C) plans are offered by private insurers and set their own deductibles, copays, and an annual out-of-pocket maximum that can differ from Original Medicare. If you have a Medicare Advantage plan, you still pay your Part B premium.

Medigap (Medicare Supplement) plans help pay Original Medicare's out-of-pocket costs like deductibles and coinsurance. High-deductible versions of Plans F and G (and Plan J, which is no longer sold to new enrollees) require you to pay a set amount before the plan begins to help — for 2026 that deductible is $2,950, effective January 1, 2026.

Programs may help if money is tight. Medicare Savings Programs (MSPs) can help pay premiums and other costs, and Extra Help (Low-Income Subsidy) lowers Part D drug costs, for those who qualify. Income and asset limits apply and change yearly, so check the current limits with Medicare or your State Health Insurance Assistance Program (SHIP) before assuming you do or do not qualify.

Medicare Advantage plans set their own deductibles and out-of-pocket maximums; you still pay the Part B premium.
Medigap can cover Original Medicare deductibles and coinsurance; coverage varies by plan letter.
2026 high-deductible Medigap (Plans F and G; legacy Plan J): $2,950 deductible.
MSPs and Extra Help may reduce premiums and drug costs — verify current eligibility limits with an official source.

Frequently asked questions

Does the Part A deductible apply once a year or each time I'm hospitalized?

Neither exactly. The 2026 Part A deductible of $1,736 applies per benefit period. A benefit period ends after you've been out of a hospital or skilled nursing facility for 60 days in a row, and a new one (with a new deductible) begins if you're admitted again. So you could pay it more than once in a year if you have separate stays with at least a 60-day gap between them.

Is the Part B deductible annual?

Yes. The Part B deductible is $283 for 2026 and you pay it once per calendar year. After you meet it, you generally pay 20% coinsurance for most covered services while Medicare pays the other 80%.

How much does Medicare cost per month in 2026?

Most people pay $0 for Part A (with 40+ work quarters). The standard Part B premium is $202.90/mo, and Part D drug-plan premiums vary by plan. Higher earners pay IRMAA surcharges, which can raise the total Part B premium to as much as $689.90/mo and add $14.50 to $91.00/mo to a Part D premium.

What is the 2026 cap on out-of-pocket drug costs?

For 2026, your out-of-pocket spending on covered Part D drugs is capped at $2,100 for the year. Once you reach that amount, you pay nothing more for covered drugs for the rest of the calendar year.

How can I lower my Medicare deductibles and out-of-pocket costs?

Options include a Medigap plan to cover Original Medicare's deductibles and coinsurance, choosing a Medicare Advantage plan with a lower out-of-pocket maximum, and, if you have limited income, applying for a Medicare Savings Program or Extra Help. Eligibility limits change each year, so confirm them with Medicare or your local SHIP.
