Medicare Part B Deductible 2027: Expected Premium, Cost and Changes

The Medicare Trustees also project that the standard Part B monthly premium could rise from $202.90 in 2026 to $209.50 in 2027.

Medicare Part B Deductible 2027: Medicare users may see higher health bills again in 2027. A recent Medicare Trustees Report puts the Part B deductible for 2027 at $292.

That number is $9 more than the 2026 deductible of $283. In percentage terms, it works out to roughly a 3.2% rise.

It is worth noting one key point. The $292 figure is still a forecast. The final Part B deductible for 2027 will be set by the Centers for Medicare & Medicaid Services, likely sometime later in 2026.

For many people who rely on Social Security or other fixed income, even a small jump can matter. The deductible is added to the monthly Part B premium, along with other health-related costs.

Medicare Part B Deductible 2027: What Is the Latest Projection?

The latest projection puts the 2027 Medicare Part B deductible at $292.

Here’s how the numbers compare:

  • 2025: $257
  • 2026: $283
  • 2027 projected: $292

The 2026 figure of $283 is official. CMS announced it as part of the 2026 Medicare cost-sharing amounts. The 2027 figure comes from the 2026 Medicare Trustees Report’s intermediate projections.

The projected $292 amount therefore should be treated as a planning figure rather than a final bill.

How Much Could Medicare Part B Cost in 2027?

The deductible is only one part of the cost.

The Medicare Trustees also project that the standard Part B monthly premium could rise from $202.90 in 2026 to $209.50 in 2027.

Combined with the projected $292 deductible, a beneficiary paying the standard premium could be looking at approximately $2,806 in annual Part B premium payments plus the deductible, before considering coinsurance or other Medicare-related expenses.

The $209.50 premium is also a projection and should not be confused with the final 2027 premium.

Why Is the Medicare Part B Deductible Increasing?

Medicare Part B helps pay for medically necessary services such as physician services, outpatient hospital care, certain home health services, durable medical equipment and other covered medical services.

Each year, Medicare adjusts premiums and cost-sharing amounts based on expected program costs.

The 2026 increase was influenced largely by projected changes in healthcare prices and utilization. More broadly, Medicare spending is being pushed higher by factors including healthcare utilization, medical costs and an aging population.

That doesn’t mean every beneficiary will experience the same total healthcare bill. Actual costs depend on the services a person uses, supplemental coverage, Medicare Advantage enrollment, income and other factors.

What Is the Medicare Part B Deductible?

The Part B deductible is the amount a beneficiary generally has to pay for covered Part B services before Medicare begins paying its share.

For most covered Part B services, after the deductible has been met, beneficiaries generally pay 20% of the Medicare-approved amount, while Medicare pays the remaining 80%.

For example, if the projected $292 deductible becomes the final 2027 amount, a beneficiary would generally have to meet that annual deductible before standard Part B cost-sharing applies to services subject to the deductible.

The exact amount a person pays can vary depending on the service, whether the provider accepts Medicare assignment and whether the beneficiary has additional coverage.

Will Everyone Pay the $292 Medicare Part B Deductible?

Not necessarily. The $292 figure is the projected standard Part B deductible for beneficiaries in Original Medicare. A person’s actual out-of-pocket costs can be different depending on their coverage.

For instance, someone who signs up for Medicare Advantage usually gets Part A and Part B through private plans that Medicare has approved. Those plans can set their own rules for deductibles, copays, coinsurance, and limits on what you pay out of pocket.

On the other hand, people with Medigap may get parts of Medicare’s cost sharing paid, depending on what their plan says.

So the estimated $292 should not be treated as the exact sum that every Medicare user will have to pay themselves.

Medicare Part B Premium Vs. Deductible: What’s The Difference?

These two items get mixed up a lot.

Part B premium is the monthly charge. It keeps Part B coverage in place. For 2027, the standard premium is expected to be $209.50 each month.

Part B deductible is a yearly amount. In most cases, you pay it for Part B services first. After that, Medicare starts sharing the costs in its usual way.

You can pay both in the same year. That includes the monthly premium and the yearly deductible. The premium and the deductible are not the same thing.

Could the $292 Projection Change?

Yes. This is one of the most important points for anyone searching for the 2027 Medicare Part B deductible.

The $292 figure comes from the 2026 Medicare Trustees Report, which provides projections for future Medicare costs. It is not the final CMS rate announcement.

The Trustees’ report itself lists $209.50 as the estimated 2027 monthly Part B premium, while the current 2026 premium is $202.90.

Historical projections can change before the final annual amounts are announced. For example, reporting comparing the 2025 Trustees’ projection with the eventual 2026 figure shows that the earlier projection for the 2026 deductible was higher than the $283 amount ultimately finalized.

That is why beneficiaries should use $292 as an estimate for financial planning, not as a guaranteed 2027 charge.

When Will the Official 2027 Medicare Part B Deductible Be Announced?

CMS usually posts the next year’s Medicare Part A and Part B costs in the fall. That includes premiums, deductibles, and coinsurance.

For 2027, people should look for CMS to publish the update sometime later in 2026.

Until CMS releases the new figures, the clearest Medicare-based estimate in the actuarial reporting is the $292 number.

How Much Has the Part B Deductible Gone Up?

This is why many beneficiaries keep an eye on the changes.

The deductible moved like this:

  • $257 in 2025
  • $283 in 2026
  • $292 projected for 2027

The change from 2025 to 2026 was bigger, at $26. The estimate for 2027 is smaller, at $9. In percentage terms, that is roughly 3.2%. The smaller expected jump may feel easier than what happened in 2026.

Higher-income Beneficiaries And Part B

Not everyone uses the same Part B premium. Some higher-income beneficiaries pay an extra amount called the Income-Related Monthly Adjustment Amount, or IRMAA.

IRMAA is not part of the Part B deductible. It adds to the monthly premium when income is above the stated limits.

For 2026, the standard Part B premium is $202.90. Higher-income beneficiaries pay more on top of that. CMS’s 2026 tables show that total monthly Part B premiums rise a lot for those covered by IRMAA.
