What's changing with Medicare costs in 2025

Medicare premiums, deductibles, and out-of-pocket limits are increasing in 2025, but the amounts vary depending on which part of Medicare you use and when you enrolled. The Part B premium — the monthly charge for doctor visits and outpatient care — is rising to $185 per month for most people, up from $174.70 in 2024. The Part A deductible for hospital stays is going up to $1,676 per benefit period, compared to $1,600 in 2024.

These changes happen every year because Medicare adjusts for inflation and changes in healthcare costs. The increases are set by federal formula, not by your individual situation. If you receive Social Security, your Medicare Part B premium may be deducted directly from your check, so you'll see the difference there starting in January 2025.

Key Takeaways

  • Part B premiums are rising to $185 per month in 2025, an increase of about $10 from 2024.
  • Part A hospital deductibles are increasing to $1,676 per benefit period, up $76 from the previous year.
  • Part D prescription drug coverage premiums and cost-sharing amounts also increase yearly, though the exact amounts depend on your specific plan.
  • If you have a Medigap or Medicare Advantage plan, your premiums may increase separately from the standard Medicare increases.
  • You can review and change your coverage during the Annual Enrollment Period, which runs October 15 through December 7 each year.

Part B premium and deductible increases

The Part B premium increase to $185 per month affects most people on Original Medicare. However, if you're a higher-income earner, you may pay more through an Income-Related Monthly Adjustment Amount (IRMAA). This surcharge applies if your modified adjusted gross income from two years prior exceeds certain thresholds — for 2025, that means income reported on your 2023 tax return.

The Part B deductible — the amount you pay out of pocket before Medicare starts covering your doctor visits — remains at $240 for 2025, unchanged from 2024. However, the Part A deductible for hospital care is rising to $1,676. This is the amount you pay for the first 60 days of a hospital stay in each benefit period.

Part D prescription drug changes

Part D plans, which cover prescription medications, adjust their premiums and cost-sharing amounts annually. The specific increases depend on which plan you're enrolled in, since each insurance company sets its own rates. Some plans may increase by just a few dollars per month, while others could go up more significantly.

More importantly, the Part D coverage gap — the "donut hole" where you pay more out of pocket for drugs — has different cost-sharing amounts in 2025. Once you and your plan have spent $5,850 on covered drugs, you enter the gap. The exact amounts you'll pay in the gap depend on your plan, but this threshold changes yearly.

You should review your current Part D plan during the Annual Enrollment Period to see if a different plan might offer better rates for the medications you take. Switching plans costs nothing and can sometimes save you hundreds of dollars per year.

Medicare Advantage plan premium changes

If you have a Medicare Advantage plan (Part C), your premium is separate from the Part B premium increase. Advantage plans are offered by private insurance companies and include coverage for hospital, doctor, and usually prescription drugs all in one plan. Each company sets its own premium, so increases vary widely — some plans may stay the same or even decrease, while others go up.

Many Medicare Advantage plans charge $0 in monthly premium but make up the cost through higher deductibles, copays, or out-of-pocket limits. In 2025, the maximum out-of-pocket limit for Advantage plans is $8,850 for in-network care. This is the most you'll pay in a year for covered services before the plan pays 100 percent.

Medigap (supplemental insurance) premium increases

If you have a Medigap policy — supplemental insurance that covers costs Original Medicare doesn't pay — your premium increase depends on your specific policy and insurance company. Medigap premiums are not set by Medicare; each insurance company decides its own rates. Some companies increase premiums annually by 3 to 5 percent, while others may increase more or less.

Medigap policies are standardized by the federal government, meaning Plan G from one company covers the same benefits as Plan G from another company. However, premiums can differ significantly between companies. If your current Medigap premium is rising sharply, you may be able to switch to a different company's plan with the same letter designation and potentially pay less.

How to prepare for the 2025 increases

Review your current coverage now, before the Annual Enrollment Period begins on October 15. Look at your Part D plan to see if your medications are still covered at the same cost-sharing level. Check whether your Medicare Advantage plan's network still includes your doctors and preferred hospitals. If you have Medigap, compare quotes from other companies offering the same plan letter.

If you're on a tight budget, contact your plan directly to ask about programs that help with premiums and cost-sharing. Many insurance companies offer low-income subsidy programs for Part D, and some Advantage plans have programs for people with limited income. Your local Area Agency on Aging can also connect you with counselors who review your coverage for free.

Keep your Medicare Summary Notice (the annual statement you receive from Medicare) and any notices from your insurance company. These documents show what you paid in 2024 and help you understand what to expect in 2025.

When the increases take effect

Most Medicare premium and deductible changes take effect on January 1, 2025. If you receive Social Security, your Part B premium will be deducted from your January payment. If you pay your Part B premium directly to Medicare, you'll receive a new bill with the higher amount.

If you make changes during the Annual Enrollment Period (October 15 through December 7, 2024), those changes also take effect January 1, 2025. Any plan you switch to will have its own 2025 premiums and cost-sharing amounts, so compare the total cost — premium plus expected out-of-pocket costs for your medications and doctor visits — not just the monthly premium.

Frequently Asked Questions

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

No. If Medicare is deducted from your Social Security, the deduction increases, but your total Social Security payment does not decrease. You'll receive less in your pocket because more goes to Medicare, but your benefit amount itself stays the same.

Can I change my Medicare plan if I don't like the 2025 increases?

Yes. The Annual Enrollment Period runs October 15 through December 7 each year, and any changes take effect January 1. You can switch from Original Medicare to Medicare Advantage, change Advantage plans, switch Medigap policies, or change Part D plans. You can make these changes once per year during this window.

What if I can't afford the higher premiums?

Contact your insurance company or local Area Agency on Aging to ask about low-income programs. Medicare also has a Part D low-income subsidy program that helps with premiums and cost-sharing if your income is below certain limits. You can also call 1-800-MEDICARE to discuss your options.

Do all Medicare Advantage plans increase by the same amount?

No. Each insurance company sets its own premium for its Medicare Advantage plans. Some plans may increase significantly, others slightly, and some may even decrease or stay the same. This is why comparing plans during enrollment is important — the lowest-cost plan this year may not be the lowest next year.

If I don't change my plan, will I automatically stay in the same coverage?

Yes. If you do nothing during the Annual Enrollment Period, your current plan continues into 2025 with the new premium and cost-sharing amounts. However, it's still worth reviewing your plan each year to make sure it still meets your needs and budget.
