As of 2026, the cost of Medicare Part B 2026 has increased, directly affecting millions of Americans enrolled in Original Medicare. The standard monthly premium for Medicare Part B is $202.90, and the annual deductible is $283, reflecting officially confirmed rates now in effect nationwide. These updated figures apply to most beneficiaries and represent a noticeable rise compared to 2025.
This guide explains the exact costs, income adjustments, penalties, and what beneficiaries should expect this year.
What Medicare Part B Covers
Medicare Part B helps pay for medically necessary services and preventive care outside hospital stays. Coverage includes:
- Doctor and specialist visits
- Outpatient hospital services
- Preventive screenings and vaccines
- Durable medical equipment such as wheelchairs and walkers
- Some home health services
Part B operates through a combination of premiums, deductibles, and coinsurance.
Standard Monthly Premium in 2026
The standard Medicare Part B premium for 2026 is:
- $202.90 per month
This represents an increase of $17.90 from the 2025 premium of $185. Most beneficiaries pay the standard amount. For those receiving Social Security, the premium is typically deducted directly from monthly benefit payments.
The increase reflects higher projected outpatient care spending and utilization trends across the Medicare population.
2026 Annual Deductible
Before Medicare begins paying its share, beneficiaries must meet the annual deductible.
- 2026 Part B Deductible: $283
This amount increased by $26 from the prior year. Once you meet the deductible, Medicare generally covers 80% of approved services. You are responsible for the remaining 20% unless you have supplemental coverage.
Income-Related Monthly Adjustment Amount (IRMAA)
Not every enrollee pays the standard premium. Higher-income beneficiaries pay additional amounts known as IRMAA.
In 2026:
- Income thresholds begin at $109,000 for individuals
- Thresholds begin at $218,000 for married couples filing jointly
Depending on income, monthly Part B premiums can rise substantially. IRMAA surcharges range from approximately $81.20 to $487.00 per month in addition to the base premium.
That means total monthly costs for some high-income beneficiaries can exceed $600 per month.
The Social Security Administration determines income brackets using tax returns from two years earlier.
Coinsurance Costs After the Deductible
After you pay the $283 deductible, Medicare Part B typically covers 80% of approved outpatient services.
You pay:
- 20% coinsurance for most services
- Any charges above the Medicare-approved amount if a provider does not accept assignment
These ongoing costs are part of the overall cost structure beneficiaries must consider when budgeting.
Late Enrollment Penalty
Delaying enrollment without qualifying coverage can permanently increase your premium.
The penalty equals:
- 10% of the standard premium for each full 12-month period you were eligible but did not enroll
This higher premium remains in effect for as long as you have Part B coverage.
Medicare Advantage and Part B Premiums
Even if you enroll in a Medicare Advantage plan, you must still pay your Part B premium.
Some Advantage plans offer Part B premium reductions. In 2026, a significant portion of plans provide partial or full rebates that reduce what you pay out of pocket. However, these vary by location and plan availability.
Special Immunosuppressive Drug Coverage Premium
Certain kidney transplant recipients may choose limited Part B coverage for immunosuppressive drugs after losing full Medicare eligibility.
For 2026:
- The monthly premium for this limited coverage option is $121.60
This program helps ensure transplant recipients maintain access to necessary medications.
