Average Cost of Medicare Part B in 2026
Medicare Part B Monthly Premium for 2026
The standard monthly Medicare Part B premium for 2026 is $202.90, marking a $17.90 increase from the previous year. This amount applies to most beneficiaries whose modified adjusted gross income (MAGI) is below or equal to $109,000 for individuals, or $218,000 for couples, as reported on their 2024 tax returns. Medicare Part B is a core component of Original Medicare, covering medically necessary outpatient services, doctor visits, and preventive care. For a foundational overview of Medicare as a whole, review What to Know About Medicare: Key Facts & Coverage.
Beneficiaries with higher incomes may see a monthly premium up to $689.90 due to income-related adjustments (see IRMAA section). For most, however, $202.90 remains the standard charge unless additional surcharges, penalties, or special circumstances arise.
Premium Deduction: The majority of Medicare recipients have their Part B premium automatically deducted from their monthly Social Security benefit, simplifying payment processes and ensuring consistent coverage.
Annual Deductible and Coinsurance Explained
In 2026, the Part B annual deductible rises to $283, up $26 from the previous year. This deductible is a once-per-year payment required before Medicare begins paying its share for covered services. After the deductible is met, Medicare pays 80% of approved service costs. Beneficiaries are responsible for the remaining 20%-known as coinsurance-for qualifying outpatient care, physician visits, durable medical equipment, and preventive screenings.
| Cost Component | 2026 Amount | Notes |
|---|---|---|
| Standard Monthly Premium | $202.90 | MAGI ≤ $109,000 (individual)/$218,000 (couple) |
| Annual Deductible | $283 | Owed once per year before 80% coverage starts |
| Coinsurance | 20% | For Part B-covered services after deductible |
For those seeking fuller coverage for out-of-pocket costs, Oregon Medicare Supplemental Plans Guide 2026 details Medigap policies that can cover deductibles and coinsurance, reducing or eliminating after-deductible expenses.
IRMAA: Higher Premiums for High-Income Earners
Some beneficiaries pay more than the standard Medicare Part B 2026 premium due to the Income-Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your monthly premium if your MAGI-as reported on your 2024 federal tax return-exceeds certain thresholds. The Social Security Administration (SSA) determines who is subject to IRMAA and notifies you by mail about your exact amount each year.
2026 IRMAA Brackets and Premiums
Here’s a general breakdown of 2026 IRMAA brackets for individuals and married couples filing jointly:
- ≤ $109,000 (individual) / $218,000 (joint): $202.90 (standard premium)
- $109,000-$137,000 (individual): Increased premium – starting ~$284.10
- $137,000-$163,000: Higher adjustment applies
- $163,000-$500,000: Further increases, up to $689.90
- ≥ $500,000 (individual) / $750,000 (couple): Maximum IRMAA premium of $689.90
Note: Married individuals filing separately are subject to different, often lower, thresholds for IRMAA application. For the most current full IRMAA tables and a complete fee schedule, visit the Medicare.gov Part B costs page or your Social Security statement.
The Medicare IRMAA 2026 adjustment ensures that higher-income enrollees contribute a larger share to the cost of Part B coverage. IRMAA is recalculated annually, so your income from two years prior always determines the charge for the present year.
How Your Premiums Are Paid
For most Medicare beneficiaries, the monthly Part B premium is automatically deducted from Social Security benefits-no additional action is required. This deduction applies to standard premiums as well as any IRMAA surcharges. If you are not receiving Social Security, Medicare will bill you directly, or your premium may be paid via the Railroad Retirement Board (RRB) if you collect related benefits.
If you wish to change your payment method or have questions about premium collection, consult your SSA or RRB account online. Additionally, the Social Security Administration announces an annual cost-of-living adjustment (COLA); for 2026, an estimated 2.8% increase (~$56/month) in Social Security benefits will help offset higher premiums for many recipients.
Understanding how premium deductions work is important when evaluating supplemental coverage or considering enrollments in alternative plans.

Year-over-Year Changes in Part B Costs
The Medicare premium changes from year to year reflect adjustments in healthcare costs, policy decisions, and program projections. The standard monthly premium increased from $185.00 in 2025 to $202.90 in 2026, while the annual deductible rose from $257 to $283. These updates stem from predicted shifts in utilization and spending patterns, such as new technologies or reduced costs in Medicare paying for certain outpatient services (notably, skin substitute payments have been moderated for 2026).
- Premium: Up $17.90 from 2025
- Annual Deductible: Increased by $26
These increases are set according to the Social Security Act, following a process that involves recommendations by Medicare trustees and experts. The ongoing alignment between Social Security benefit adjustments and Medicare Part B costs helps maintain affordability for the majority of beneficiaries.

FAQs: Medicare Part B Premiums and Payments
Who pays the standard Medicare Part B 2026 premium?
Most Medicare beneficiaries pay the standard $202.90 monthly for Part B unless their income is high enough to trigger IRMAA. IRMAA is applied only to those with incomes exceeding $109,000 (individual) or $218,000 (couple) as determined by IRS data from two years earlier.
Does the Part B deductible reset?
Yes. The 2026 Part B deductible resets each January 1, requiring you to pay the full amount before Medicare’s 80% coinsurance benefit takes effect.
What if I have low income?
Eligible beneficiaries with limited income and resources may qualify for state programs-such as the Qualified Medicare Beneficiary (QMB) program-which can help pay the Part B premium, deductible, and coinsurance. Application is typically through your state Medicaid office. Find more details at What to Know About Medicare.
Does the Social Security COLA cover premium increases?
For most enrollees, the annual Social Security COLA helps offset Medicare premium increases. The 2026 COLA is projected at 2.8%, which translates into an average $56/month boost that counterbalances the $17.90 increase in the Part B premium.
Are there different premiums for immunosuppressive drug coverage?
Yes. Those enrolled in the new Part B-only benefit for immunosuppressive drugs (for kidney transplant recipients who otherwise lack full Medicare) pay a standard premium of $121.60 for 2026, plus IRMAA if applicable.
What happens if I enroll late?
Delaying enrollment in Part B without creditable coverage can result in a late enrollment penalty-a permanent increase in your monthly premium. The penalty accrues for every 12-month period you delay; apply on time to avoid this extra cost. For in-depth information on initial and special enrollment periods or Medigap protections, see Medicare Supplement Free Look Period Guide.
Where can I check my personalized premium or IRMAA charges?
Your exact premium-including any IRMAA adjustment-is detailed in your annual Social Security benefit statement. You can also contact the Social Security Administration or Medicare directly for questions about your individual situation.
Do these 2026 costs apply to Medicare Advantage (Part C) or Part D?
The figures above are for Original Medicare Part B only. Medicare Advantage (Part C) and prescription drug (Part D) plans may have different premiums and cost-sharing; visit What Does Medicare Part C Pay For? Coverage Explained or How Do I Get Medicare Part C? Eligibility and Enrollment for details about costs and coverage options under those plans.
