Medicare premiums, deductibles, and copays are increasing in 2025, but the amounts vary by the type of coverage you have

Yes, Medicare costs are going up in 2025. The monthly premium for Part B (doctor visits and outpatient care) is rising, Part A deductibles are higher, and copayment amounts for some services are changing. The exact increase depends on whether you have Original Medicare, a Medicare Advantage plan, or a Medigap supplemental policy — each one adjusts differently.

The Social Security Administration announces these changes each October for the following year. The increases are tied to inflation and the actual cost of providing care, so the dollar amounts shift year to year. If you are on a fixed income, even a modest increase can affect your budget, so it helps to know what is changing and when those changes take effect.

Key Takeaways

  • Part B premiums and Part A hospital deductibles increase each year; the 2025 amounts were announced in October 2024 and take effect January 1.
  • Original Medicare, Medicare Advantage, and Medigap plans all have different cost structures, so the impact on your out-of-pocket spending varies by plan type.
  • If you receive Social Security, your Part B premium is usually deducted automatically, so you will see the new amount in your January payment.
  • Medicare Advantage plans may change their copays, coinsurance, and coverage rules each year, so reviewing your plan during open enrollment (October 15 to December 7) helps you decide whether to stay or switch.

Part B Premium and Part A Deductible Changes for 2025

Part B covers doctor visits, lab work, imaging, and outpatient hospital services. The standard Part B premium for 2025 is $174.70 per month, up from $164.90 in 2024. If you have higher income, you may pay an additional amount called an Income-Related Monthly Adjustment Amount (IRMAA), which is calculated based on your tax return from two years prior.

Part A covers hospital stays, skilled nursing facility care, and some home health services. The Part A deductible for 2025 — the amount you pay out of pocket before Medicare begins to pay — is $1,676 per benefit period, up from $1,632 in 2024. If you are admitted to a hospital again within 60 days of your previous discharge, you pay the deductible again for that new benefit period.

These amounts take effect January 1, 2025. If you receive Social Security, Medicare will deduct your new Part B premium from your January payment automatically. If you do not receive Social Security, you will receive a bill from Medicare.

How Original Medicare Costs Differ From Medicare Advantage

Original Medicare (Part A and Part B) has the same deductibles and copayments for everyone nationwide. Once you meet your Part B deductible ($240 for 2025), you typically pay 20 percent coinsurance for most services. There is no annual out-of-pocket maximum, which means your costs can continue to rise if you need frequent or expensive care.

Medicare Advantage plans (Part C) are offered by private insurance companies and bundle Part A, Part B, and usually Part D (prescription drugs) into one plan. Each plan sets its own copays, coinsurance, and deductibles — they vary widely and change year to year. Advantage plans do have an annual out-of-pocket maximum, which limits your total spending, but you must use in-network providers or pay more.

Because Advantage plans change their cost structure annually, the plan that was cheapest for you in 2024 may not be the cheapest in 2025. This is why reviewing your options during open enrollment is important. You can compare plans using the Medicare Plan Finder tool on Medicare.gov, or call 1-800-MEDICARE to speak with someone who can walk you through the options.

Medigap Supplemental Coverage and 2025 Costs

Medigap policies are sold by private insurance companies and help pay the costs that Original Medicare does not cover — deductibles, coinsurance, and copayments. Medigap premiums are set by the insurance company, not by Medicare, and they vary by company, state, and the plan letter you choose (Plan A, Plan B, Plan G, and so on).

When Medicare costs go up, Medigap premiums often rise as well, though the timing and amount depend on your insurer. Some companies increase premiums in January, others at your policy anniversary date. If you have a Medigap policy, your insurance company will send you a notice of any premium changes before they take effect.

If you are unhappy with a premium increase, you can switch to a different Medigap plan or a different insurance company, though you may face medical underwriting depending on your age and health status. Some states have rules that make switching easier; your state insurance commissioner's office can tell you what applies where you live.

Part D Prescription Drug Coverage Changes

Part D covers prescription medications. Like Medicare Advantage plans, Part D plans are run by private insurers and change their formularies (the list of covered drugs), copayments, and deductibles each year. A drug that cost you $10 in 2024 may cost $15 in 2025, or it may move to a higher tier requiring a larger copay.

If you take regular medications, it is worth checking whether your drugs are still covered at the same cost in your current plan. You can use the Medicare Plan Finder or call your plan directly. If your costs are rising significantly, you may find a different Part D plan that covers your medications more affordably.

Open enrollment runs from October 15 to December 7 each year. Changes take effect January 1. If you miss the important date, you cannot switch plans until the next open enrollment period, unless you may have access to for a Special Enrollment Period due to a life event like moving or losing other coverage.

When Changes Take Effect and How to Prepare

All Medicare changes for 2025 take effect on January 1. If you are on Social Security, your new Part B premium will be deducted from your January payment — you do not need to do anything. If you do not receive Social Security, Medicare will mail you a bill.

If you have a Medicare Advantage or Part D plan, your plan will send you an updated member handbook and a notice of changes before January 1. Read these documents carefully, especially if you take regular medications or see specific doctors. If your plan is no longer a good fit, you have until December 7 to switch to a different plan.

If you have Original Medicare and a Medigap policy, check your Medigap insurer's notice of any premium changes. If the increase is steep, contact your insurer to ask whether you can switch to a lower-cost plan letter, or call your state insurance commissioner's office for guidance on your options.

Frequently Asked Questions

Will my Social Security check go down because of the Medicare premium increase?

No. Social Security adjusts for inflation each year with a cost-of-living adjustment (COLA). Your benefit amount increases, and then Medicare deducts your new Part B premium. The net change to your check depends on whether the COLA is larger or smaller than the premium increase, but your benefit itself does not shrink.

Can I switch Medicare plans after December 7?

Not during the regular open enrollment period. If you miss the important date, you are locked into your plan until the next October 15. However, if you experience a may have access to life event — such as moving, losing other coverage, or getting married — you may be able to switch during a Special Enrollment Period. Call Medicare at 1-800-MEDICARE to ask whether your situation qualifies.

What if I cannot afford the new premiums?

Medicare has programs that may help pay premiums and cost-sharing for people with limited income. These include the Part D Low-Income Subsidy and the Medicare Savings Programs. You can learn more by calling 1-800-MEDICARE or contacting your local Medicaid office, which administers these programs in your state.

Do all Medicare Advantage plans increase their copays by the same amount?

No. Each plan sets its own copays and deductibles independently. One plan may raise copays by $5, while another raises them by $15 or keeps them the same. This is why comparing plans during open enrollment is important — the plan that was cheapest in 2024 may not be the cheapest in 2025.

Where can I find the exact 2025 costs for my specific plan?

Use the Medicare Plan Finder at Medicare.gov, enter your zip code and medications, and it will show you all available plans with their 2025 premiums, deductibles, and copays. You can also call 1-800-MEDICARE to speak with someone who can help you compare plans over the phone.
