Medicare Part B Costs in 2026: Premiums, Deductible, and What You Need to Know

Every January, Medicare Part B costs change — and 2026 brought one of the bigger jumps in recent years. If you’re on Medicare or about to enroll, here’s exactly what changed, what it means for your budget, and why skipping Part B is rarely a good idea.

What Are the 2026 Medicare Part B Premium and Deductible?

Starting January 1, 2026, the standard monthly Part B premium is $202.90 — up $17.90, or about 9.7%, from $185.00 in 2025. The annual Part B deductible is $283 in 2026, up $26 from $257 in 2025. These figures come directly from the CMS 2026 Medicare Parts A & B Premiums and Deductibles Fact Sheet and are confirmed on the official Medicare.gov 2026 Costs Fact Sheet.

This is a larger-than-usual increase, driven mainly by rising healthcare utilization and medical inflation.

Will I Pay More If I Have a Higher Income?

Possibly. If your income is above certain thresholds, you’ll pay an Income-Related Monthly Adjustment Amount (IRMAA) — an insurance term for a surcharge based on your tax return from two years prior. For 2026, if your 2024 income was at or below $109,000 (single) or $218,000 (married filing jointly), you pay the standard $202.90. Above that, premiums step up through several tiers, topping out at $689.90/month for the highest earners, according to the Social Security Administration.

If your income recently dropped because you retired or experienced another life-changing event, you can ask Social Security to reconsider your IRMAA bracket — you don’t have to accept the higher rate automatically.

What Does Medicare Part B Actually Cover?

Part B is the portion of Medicare that covers medically necessary outpatient care — the services you receive when you’re not admitted to a hospital. That includes:

• Doctor visits (primary care and specialists)
• Lab tests and blood work
• X-rays, MRIs, and other diagnostic imaging
• Outpatient surgeries and procedures
• Preventive services like mammograms, colonoscopies, and annual wellness visits
• Vaccines (flu, COVID-19, shingles)
• Durable medical equipment like walkers, wheelchairs, and oxygen
• Outpatient mental health care

Why Can’t I Just Skip Part B to Save Money?

Some seniors consider skipping Part B to avoid the monthly premium, but this usually backfires for three reasons:

1. You’ll pay 100% out-of-pocket for the outpatient services listed above, since Part B is what covers them.
2. You may face a lifelong late enrollment penalty — an extra 10% of the standard premium for every full 12-month period you were eligible but didn’t enroll, added to your bill permanently, according to Medicare.gov.
3. Part B is required to join a Medicare Advantage plan. You cannot enroll in Part C unless you have both Part A and Part B active.

The one common exception: if you’re still actively working and covered by a qualifying employer group health plan (20+ employees), you may be able to delay Part B penalty-free and enroll later using a Special Enrollment Period.

How Do I Pay My Part B Premium?

Most people have their Part B premium deducted automatically from their monthly Social Security or Railroad Retirement Board benefit check, so you may not notice a separate bill. If you’re not yet collecting Social Security, or if you have Medicare but haven’t started benefits, you’ll receive a quarterly premium bill (Medicare Premium Bill, or Form CMS-500) directly from Medicare, which you can pay online, by mail, or by phone.

What You Should Do Now

• Check your Social Security benefit statement to see exactly what you’re paying for Part B in 2026.
• If your income dropped recently, ask Social Security whether you qualify for a lower IRMAA bracket.
• If you’re nearing 65 or still working, talk with a licensed advisor about whether to enroll in Part B now or delay it based on your employer coverage.
• If cost is a concern, ask about Medicare Savings Programs, which can help pay your Part B premium if you qualify based on income.

Frequently Asked Questions

Why did my Part B premium go up so much this year?

CMS raises the standard premium annually based on projected program costs. The 2026 increase of $17.90 was larger than most recent years due to rising healthcare utilization and medical inflation.

Do I have to pay the Part B deductible every year?

Yes. The $283 deductible in 2026 resets annually — once you’ve paid that amount out-of-pocket for Part B-covered services, Medicare begins paying its share (usually 80%) for the rest of the year.

Can I lower my Part B costs?

You can’t change the standard premium, but if your income is limited, you may qualify for help through Medicaid or a Medicare Savings Program. A licensed advisor can help you check.

Does Part B cover prescription drugs?

Not usually. Part B covers drugs administered in a clinical setting, like chemotherapy infusions or certain vaccines, but everyday prescriptions you pick up at a pharmacy are covered under a separate Part D prescription drug plan or through a Medicare Advantage plan that includes drug coverage.
