The Centers for Medicare & Medicaid Services (CMS) released the 2026 Medicare Part A and Part B premiums, deductibles and coinsurance amounts on November 14, 2025. The standard monthly Part B premium is $202.90 in 2026, up $17.90 from $185.00 in 2025, an increase of nearly 10 percent. The annual Part B deductible rose to $283.
Looking ahead, the 2026 Medicare Trustees Report projects the standard Part B premium at $209.50 in 2027. That is a projection, not the official figure. CMS typically announces the official premium and deductible in mid-November, and this page will be updated with the confirmed 2027 amounts when they are released.

Medicare Part B Premium and Deductible: 2025, 2026 and 2027 Projection
The table below compares the confirmed 2025 and 2026 amounts with the Trustees Report estimates for 2027.
| Part B item | 2025 | 2026 | 2027 (projected) |
|---|---|---|---|
| Standard monthly premium | $185.00 | $202.90 | $209.50 |
| Annual deductible | $257 | $283 | $292 |
Medicare Part B covers physicians’ services, outpatient hospital services, certain home health services, durable medical equipment and other medical services not covered by Part A. According to CMS, the 2026 increase was mainly due to projected price changes and assumed utilization increases consistent with historical experience.

2027 Medicare Part B Premium Projection
The Trustees Report estimates a standard Part B premium of $209.50 a month in 2027, an increase of $6.60, or about 3.3 percent, over 2026. The report also estimates the annual deductible at $292. Both numbers are estimates that CMS will replace with official figures this fall.
Projections can move before the official announcement. The 2025 Trustees Report had projected a 2027 premium of $218.60, more than $9 higher than the current estimate. For a deeper look at how the projection is built and how it could change, see the projected Medicare premium increase for 2027.
How Part B Premiums Are Paid
Most Medicare enrollees have the Part B premium deducted from their monthly Social Security benefit. Those who do not yet receive Social Security, or whose benefit is too small to cover it, are billed directly. Details on each method are in how Medicare Part B beneficiaries can pay their monthly premiums.
For many people whose premiums are deducted from Social Security, a hold harmless provision limits the premium increase to the dollar amount of their Social Security cost-of-living adjustment (COLA). It does not protect people who pay an income-related surcharge or who are newly enrolled. The current COLA Watch page tracks the COLA side of that calculation.
2026 Part B Income-Related Monthly Adjustment Amounts
Since 2007, higher-income beneficiaries have paid more for Part B through the Income-Related Monthly Adjustment Amount (IRMAA). CMS says IRMAA affects roughly 8 percent of people with Part B. The amount is based on modified adjusted gross income (MAGI) from a tax return filed two years earlier, as reported to the Social Security Administration (SSA).
The 2026 total monthly Part B premiums for people with full Part B coverage are shown below.
| MAGI, individual return | MAGI, joint return | IRMAA | Total monthly premium |
|---|---|---|---|
| $109,000 or less | $218,000 or less | $0.00 | $202.90 |
| Above $109,000 to $137,000 | Above $218,000 to $274,000 | $81.20 | $284.10 |
| Above $137,000 to $171,000 | Above $274,000 to $342,000 | $202.90 | $405.80 |
| Above $171,000 to $205,000 | Above $342,000 to $410,000 | $324.60 | $527.50 |
| Above $205,000 to under $500,000 | Above $410,000 to under $750,000 | $446.30 | $649.20 |
| $500,000 or more | $750,000 or more | $487.00 | $689.90 |
Married beneficiaries who lived with their spouse at any time during the year but file separate returns pay as follows.
| MAGI, married filing separately | IRMAA | Total monthly premium |
|---|---|---|
| $109,000 or less | $0.00 | $202.90 |
| Above $109,000 to under $391,000 | $446.30 | $649.20 |
| $391,000 or more | $487.00 | $689.90 |
Medicare Part D carries its own income-related surcharge, added to the plan premium. In 2026 it ranges from $14.50 to $91.00 a month depending on income.
Anyone whose income has dropped because of retirement or another qualifying life event can ask SSA to use a more recent tax year. The process is covered in how to appeal Medicare Part B and Part D high monthly premiums, and the request forms are available from SSA.
2026 Medicare Part A Premium, Deductible and Coinsurance
Medicare Part A covers inpatient hospital, skilled nursing facility, hospice, inpatient rehabilitation and some home health care. About 99 percent of beneficiaries pay no Part A premium because they have at least 40 quarters of Medicare-covered employment. Those with 30 to 39 quarters pay a reduced premium of $311 a month in 2026, and those with fewer than 30 quarters pay the full premium of $565 a month.
| Part A cost sharing | 2025 | 2026 |
|---|---|---|
| Inpatient hospital deductible | $1,676 | $1,736 |
| Daily hospital coinsurance, days 61 to 90 | $419 | $434 |
| Daily coinsurance, lifetime reserve days | $838 | $868 |
| Skilled nursing facility daily coinsurance, days 21 to 100 | $209.50 | $217.00 |
Medicare Open Enrollment
The annual Medicare open enrollment period runs October 15 through December 7. It is the time to compare Original Medicare with Medicare Advantage and to choose a Part D prescription drug plan for the coming year. A side-by-side look at the choices is in Medicare Advantage vs. Original Medicare for federal retirees. Federal retirees who keep a Federal Employees Health Benefits (FEHB) plan can review FEHB open season dates and FEHB premium rates at the same time.
