Yes, Medicare costs are rising in 2025, but the increases vary by the type of coverage you have

Medicare premiums, deductibles, and out-of-pocket limits all increase most years, and 2025 is no exception. The amount you pay depends on which parts of Medicare you use — Part A (hospital), Part B (doctor visits), Part D (prescription drugs), or a Medicare Advantage plan. Some costs go up more than others, and the timing of when you see the change matters.

The Social Security Administration announced the 2025 changes in October 2024, so the numbers are set. If you receive Social Security, your Medicare Part B premium is deducted automatically, so you'll see the new amount reflected in your January payment. If you pay Medicare directly, you'll receive a notice in the mail showing your new premium.

Key Takeaways

  • Part B premiums increased for most people in 2025, though the exact amount depends on your income level.
  • Part A hospital deductibles and Part D prescription drug costs also rose, with the Part A deductible jumping to a higher amount than in 2024.
  • Medicare Advantage plans vary widely in their 2025 costs, so you should review your plan's new premium, deductible, and copay structure during Open Enrollment.
  • If your income changed in 2023, you may pay a higher premium surcharge called IRMAA, which affects higher-income beneficiaries.
  • You can make changes to your coverage during the annual Open Enrollment period, which runs from October 15 to December 7 each year.

Part B Premium and Deductible Changes for 2025

Part B covers doctor visits, outpatient care, and medical equipment. The standard Part B premium increased in 2025, though the exact amount depends on your income. Most people pay the standard premium, but if your modified adjusted gross income from two years prior was above a certain threshold, you pay a higher amount called an Income-Related Monthly Adjustment Amount (IRMAA). These income thresholds and surcharge amounts change each year.

The Part B deductible — the amount you pay out of pocket before Medicare starts to help — also increased for 2025. After you meet this deductible, you typically pay 20 percent of the cost for most Part B services, and Medicare covers the rest.

If you're enrolled in Original Medicare (Part A and Part B), these are the main premiums you'll see. If you have a Medigap supplemental policy, your Medigap premium may also increase, depending on your plan and insurance company.

Part A Hospital Costs Going Up

Part A covers hospital stays, skilled nursing facility care, and some home health services. You don't pay a monthly premium for Part A if you or your spouse paid Medicare taxes for at least 10 years while working. However, you do pay a deductible when you're admitted to the hospital, and this deductible increased for 2025.

The Part A deductible applies once per benefit period, not once per year. A benefit period begins when you enter the hospital and ends 60 days after you leave without being readmitted. If you're readmitted within that 60-day window, you don't pay a second deductible. Understanding this timing matters if you're planning surgery or expect a hospital stay.

If you don't have the required work history and have to pay a Part A premium, that premium also increased for 2025. The amount varies depending on how many years of work history you have.

Part D Prescription Drug Premium and Coverage Changes

Part D is optional coverage for prescription drugs. If you don't enroll when you first become may be able to access and later decide you want it, you may pay a permanent penalty for each month you went without coverage. Part D premiums, deductibles, and copays all changed for 2025, and the changes vary by plan.

Part D also includes a coverage gap, sometimes called the "donut hole," where you pay more out of pocket for drugs after you and your plan have spent a certain amount. The income level at which this gap begins and ends changes each year. Additionally, the catastrophic coverage threshold — the point at which Medicare covers most of your drug costs — also shifted for 2025.

Because Part D plans are offered by private insurance companies, each plan sets its own premium and copay amounts. Two plans may cover the same drug but charge different copays. If your current plan's costs increased significantly or your medications changed, you may want to compare other plans during Open Enrollment.

Medicare Advantage Plan Cost Changes

Medicare Advantage (Part C) plans are an alternative to Original Medicare. They're offered by private insurance companies and must cover everything Original Medicare covers, but they often include prescription drug coverage and extra benefits like dental or vision. Many plans charge no monthly premium beyond the Part B premium you already pay to Medicare, though some do charge an additional premium.

For 2025, Medicare Advantage plans can change their premiums, deductibles, copays, and out-of-pocket maximums. Some plans may have lowered their costs to attract new members, while others increased them. The out-of-pocket maximum — the most you'll pay in a year for covered services — also varies by plan and may have changed for 2025.

Because each plan is different, you should review your current plan's 2025 costs and compare them to other plans available in your area. Even if you like your plan, a competitor's plan might offer lower costs or better coverage for your specific needs. You can make changes during Open Enrollment without penalty.

Income-Related Monthly Adjustment Amount (IRMAA) Explained

If your income is above a certain level, you pay a surcharge on top of your regular Part B and Part D premiums. This surcharge is called the Income-Related Monthly Adjustment Amount, or IRMAA. The income thresholds and surcharge amounts for 2025 are based on your modified adjusted gross income from 2023 (your tax return from two years ago).

IRMAA brackets change each year, and more people may fall into a higher bracket as their income grows or as the thresholds adjust. If your income dropped significantly in 2024 — because you retired, had a major life event, or experienced a loss — you can request that Social Security recalculate your IRMAA using your current income instead of your 2023 income. This is called a life-changing event appeal.

IRMAA affects not just Part B but also Part D premiums and, in some cases, Part A premiums. The higher your income, the more you pay. Understanding whether IRMAA applies to you helps you budget for your total Medicare costs.

When to Review and Change Your Coverage

Medicare Open Enrollment runs from October 15 to December 7 each year. During this window, you can switch from Original Medicare to a Medicare Advantage plan, switch between Medicare Advantage plans, drop a Medicare Advantage plan and go back to Original Medicare, or make changes to your Part D prescription drug plan. Changes take effect on January 1 of the following year.

You should review your coverage before Open Enrollment ends because the costs and benefits available to you may have changed. If you stay in the same plan without reviewing it, you're accepting whatever cost increases or coverage changes that plan made for the new year. Many people find that a different plan offers better value once they compare options.

If you miss Open Enrollment, you generally can't make changes until the next year's Open Enrollment period, unless you have a may have access to life event such as losing employer coverage, moving to a new state, or experiencing a major change in income.

Frequently Asked Questions

How much did Medicare Part B premiums go up for 2025?

The standard Part B premium increased for 2025, but the exact amount depends on your income level. Most beneficiaries pay the standard premium, while those with higher incomes pay an additional surcharge called IRMAA. You can find your specific premium amount in the notice Medicare mailed to you or by calling 1-800-MEDICARE.

Will my Social Security check be smaller because of higher Medicare premiums?

If your Social Security benefit increases in 2025, your Medicare Part B premium increase may be partially or fully offset by the benefit increase. However, if your benefit doesn't increase or increases by less than your premium increase, your net Social Security payment could be smaller. The "hold harmless" rule protects most beneficiaries from paying more in premiums than their benefit increase, but it doesn't explore to everyone.

Can I switch Medicare plans if I don't like the 2025 cost increases?

Yes, you can switch plans during Open Enrollment from October 15 to December 7. You can move between Medicare Advantage plans, switch to Original Medicare, or change your Part D plan. Changes take effect January 1. If you miss Open Enrollment, you'll need to wait until next year unless you have a may have access to life event.

What if I can't afford the higher Medicare costs?

Several programs may help lower your costs. The Medicare Savings Program helps pay Part B premiums and deductibles for people with limited income. The Low-Income Subsidy program helps pay Part D prescription drug costs. Medicaid may also help in some states. Contact your local Medicaid office or call 1-800-MEDICARE to learn what programs you may be able to use.

Do all Medicare Advantage plans cost the same amount in 2025?

No. Each plan sets its own premium, deductible, and copay amounts. Some plans may have zero premium, while others charge $50 or more per month. Costs vary widely even among plans offered by the same insurance company. Comparing plans during Open Enrollment helps you find the lowest-cost option for your situation.
