What Changed in Medicare Costs for 2025

Yes, Medicare costs went up for 2025. The Part B premium — what you pay monthly for doctor visits and outpatient care — increased to $185 per month for most people, up from $174.70 in 2024. The Part A deductible (the amount you pay before hospital insurance kicks in) rose to $1,676 per stay, up from $1,632. Part D premiums, which cover prescription drugs, also increased, though the exact amount depends on which plan you chose.

These increases happen every year because Medicare adjusts costs based on medical inflation and the program's overall spending. The Social Security Administration announced the 2025 changes in October 2024, and they took effect on January 1, 2025. If you receive Social Security, your benefit may have increased to help offset some of these higher Medicare costs — the annual cost-of-living adjustment (COLA) for 2025 was 2.5 percent.

Key Takeaways

  • Part B premiums rose to $185 monthly in 2025, and the Part A hospital deductible increased to $1,676 per stay.
  • Part D prescription drug premiums vary by plan and insurer, so your specific increase depends on which plan covers your medications.
  • If you are on Social Security, your January payment included a 2.5 percent increase that may offset some Medicare cost increases.
  • You can review your Medicare coverage and switch plans during the annual open enrollment period, which runs from October 15 to December 7 each year.

Part B Premium and Hospital Deductible Increases

The Part B premium covers doctor visits, lab tests, X-rays, and outpatient hospital services. At $185 per month for 2025, this represents an $10.30 increase from 2024. However, if your income is above a certain threshold, you may pay a higher premium — Medicare uses a sliding scale based on your modified adjusted gross income from two years prior. For 2025, if your income was above $103,000 as a single filer in 2023, you will pay more than the standard premium.

The Part A deductible — the amount you pay out of pocket before hospital insurance covers your stay — is now $1,676 per benefit period. A benefit period begins when you enter the hospital and ends 60 days after you leave without being readmitted. If you are readmitted within that window, you do not pay a new deductible. This deductible applies to the first 60 days of a hospital stay; days 61 through 90 have a different daily copay amount.

Part D Drug Plan Premiums and Changes

Part D premiums vary widely depending on which prescription drug plan you chose and which insurance company offers it in your area. Some plans increased by a few dollars; others decreased. The only way to know your plan's 2025 premium is to check your plan documents or log into Medicare.gov and view your current plan details.

In 2025, the Part D coverage gap (the "donut hole") begins after you and your plan have spent $5,850 on covered drugs combined. Once you reach that threshold, you enter a phase where you pay a higher percentage of drug costs until you reach catastrophic coverage. The exact percentages and thresholds change yearly, so if you take expensive medications, it is worth reviewing your plan's formulary — the list of drugs it covers — to see if your medications are still covered at the same cost tier.

How Social Security COLA Affects Your Medicare Costs

The 2025 Social Security cost-of-living adjustment was 2.5 percent. If you receive Social Security and are enrolled in Medicare, your January 2025 benefit payment increased by this percentage. For someone receiving the average Social Security benefit of around $1,907 per month, the 2.5 percent increase added roughly $48 to their monthly check.

However, this increase does not automatically cover the full rise in Medicare costs. The Part B premium increase alone ($10.30) is less than half the COLA increase, but if you also pay for Part D coverage or have higher income-based premiums, your total out-of-pocket costs may have risen more than your Social Security increase. This is why reviewing your coverage each year matters — you may find a plan with lower premiums that still covers your doctors and medications.

Income-Based Premium Increases (IRMAA)

Income-Related Monthly Adjustment Amount (IRMAA) is a surcharge Medicare adds to your Part B and Part D premiums if your income exceeds certain thresholds. For 2025, if you filed taxes as a single person and your modified adjusted gross income was above $103,000, you will pay more than the standard Part B premium. The surcharge increases in steps as your income rises, with the highest earners paying significantly more.

IRMAA is based on your tax return from two years prior — so your 2025 premiums are based on your 2023 income. If your income dropped in 2024 (for example, because you retired or had a major life change), you can request that Medicare recalculate your IRMAA using your current year's income. You must file a form called the Life-Changing Event notice with Social Security to request this adjustment.

When and How to Review Your Coverage

Medicare's annual open enrollment period runs from October 15 to December 7 each year. During this window, you can switch from Original Medicare to a Medicare Advantage plan, move between Medicare Advantage plans, change your Part D drug plan, or switch back to Original Medicare. Any changes you make take effect on January 1 of the following year.

To review your options, visit Medicare.gov and use the "Find Care Providers" and "Compare Plans" tools. You can enter your current medications and see which plans cover them and at what cost. You can also call 1-800-MEDICARE to speak with a representative who can walk you through your options. Some people benefit from working with a State Health Insurance information Program (SHIP), which offers free, unbiased counseling about Medicare choices — you can find your state's SHIP by calling 1-800-MEDICARE or visiting shiptalk.org.

Medigap and Medicare Advantage Premium Changes

If you have a Medigap policy (supplemental insurance that covers costs Original Medicare does not), your premium may have increased for 2025. Medigap premiums are set by private insurance companies, not Medicare, so increases vary by insurer and by state. Some companies raise premiums annually; others use age-based pricing where your premium increases as you get older. You should receive a notice from your Medigap insurer showing your 2025 premium before January 1.

Medicare Advantage plans (Part C) also set their own premiums. Some plans lowered premiums for 2025; others raised them. If you are in a Medicare Advantage plan, check your plan's notice of changes, which insurers must send by September 30 each year. If your plan's premium or coverage changed in a way that no longer works for you, you can switch to a different plan or back to Original Medicare during open enrollment.

Frequently Asked Questions

Will my Social Security check automatically increase to cover the higher Medicare premiums?

Your Social Security benefit increased by 2.5 percent for 2025, but this does not automatically cover all Medicare cost increases. The Part B premium rose by $10.30, which is less than the average COLA increase. However, if you also pay for Part D or have income-based surcharges, your total Medicare costs may have risen more than your Social Security increase.

Can I change my Medicare plan if I do not like the 2025 costs?

Yes, but only during the annual open enrollment period from October 15 to December 7. You can switch to a different Medicare Advantage plan, change your Part D drug plan, or move between Original Medicare and Medicare Advantage. Changes take effect January 1. If you miss this window, you generally cannot change plans until the next year unless you have a may have access to life event.

What if my income went down in 2024 but my IRMAA surcharge is based on 2023 income?

You can request that Medicare recalculate your IRMAA using your 2024 income if you had a major life change such as retirement, job loss, or death of a spouse. File a Life-Changing Event notice with Social Security. You will need to provide proof of the change, such as a tax return or a letter from your employer.

Do all Part D plans increase by the same amount each year?

No. Part D premiums are set by individual insurance companies and vary by plan and location. Some plans increased for 2025; others decreased. The only way to know your specific plan's premium is to check your plan documents or log into Medicare.gov to view your current plan's details.

Is there a limit to how much Medicare costs can increase each year?

No. Medicare premiums and deductibles are adjusted annually based on medical inflation and program spending. There is no cap on how much they can increase year to year. This is why reviewing your coverage annually and comparing plans during open enrollment is important — you may find a plan with lower costs that still meets your needs.
