The main changes for 2025

Medicare is changing in 2025 in ways that affect what you pay, what drugs cost, and which doctors you can see. The biggest change is the Part D out-of-pocket spending cap: once you and Medicare combined spend $8,000 on covered drugs in 2025, Medicare pays 95% of the cost for the rest of the year. In 2024, that cap was $7,050. This means your costs go down faster once you hit the limit.

Part B premiums are rising. The standard Part B premium for 2025 is $185 per month, up from $174.70 in 2024. If you have higher income, you may pay more through Income-Related Monthly Adjustment Amounts (IRMAA). Part A deductibles are also going up: the hospital deductible for 2025 is $1,676, compared to $1,556 in 2024.

Medicare Advantage plans are changing their networks and benefits. Some plans are adding or dropping doctors and hospitals, and some are changing their drug formularies — the list of drugs they cover. If you are in a Medicare Advantage plan, you should review your plan's 2025 changes during the Annual Enrollment Period, which runs October 15 through December 7 each year.

Key Takeaways

  • The Part D out-of-pocket spending cap rises to $8,000 in 2025, meaning Medicare covers 95% of drug costs once you reach that amount for the year.
  • Part B premiums increase to $185 per month in 2025, and Part A hospital deductibles rise to $1,676.
  • Medicare Advantage plans often change their networks, covered doctors, and drug lists each year, so you should check your plan's 2025 changes during open enrollment.
  • Original Medicare (Part A and Part B) has no network restrictions, but Medigap and Medicare Advantage plans do, and their costs and coverage change annually.
  • The important date to make changes for 2025 is December 7, 2024, and changes take effect January 1, 2025.

Part D drug coverage changes and the spending cap

Part D plans set their own drug formularies each year, which means the drugs covered, the tier (cost level) they are on, and the copay or coinsurance you pay can all shift. A drug that cost you $15 in 2024 might cost $25 in 2025 under the same plan, or it might move to a tier that requires coinsurance instead of a flat copay. Some plans drop drugs entirely.

The $8,000 out-of-pocket cap is a hard ceiling. Once your costs hit that amount — counting what you paid in copays, coinsurance, and deductibles, but not what the plan paid — Medicare covers 95% of the cost for any remaining covered drugs for the rest of the calendar year. This is a real change from prior years and means your costs are more predictable once you reach the cap.

If you take expensive drugs, check whether your current plan still covers them in 2025 and at what cost. You can search your drugs on Medicare.gov using the Plan Finder tool, or call your plan directly. If your costs are rising, you may find a different Part D plan with lower costs for your specific drugs.

Part B premium and deductible increases

Part B covers doctor visits, outpatient care, and some equipment and services. The standard monthly premium for Part B in 2025 is $185, paid by most people who have Part B. If you have higher income, you pay more through IRMAA. IRMAA is based on your tax return from two years ago, so 2025 IRMAA is based on your 2023 income.

The Part B deductible for 2025 is $240 per year. This is the amount you pay out of pocket before Part B starts to pay. After you meet the deductible, you typically pay 20% of the Medicare-approved amount for most services.

If you are on a fixed income and the premium increase is a hardship, you can ask Medicare about a Part B premium reduction. Contact Social Security at 1-800-772-1213 or visit your local Social Security office to explain your situation.

Medicare Advantage plan changes

Medicare Advantage (Part C) plans contract with Medicare to provide Part A and Part B coverage, usually with added benefits like dental or vision. Because these are private plans, they can change their networks, add or drop doctors and hospitals, and change which drugs they cover. Some plans may leave your area entirely, or new plans may enter it.

If your doctor or hospital is no longer in your plan's network in 2025, you have two choices: switch to a plan that includes your doctor, or stay in your current plan and use an out-of-network provider (which usually costs more). If your plan is leaving your area, Medicare will send you a notice and you must choose a new plan during the Annual Enrollment Period.

Review your plan's 2025 changes on Medicare.gov or call your plan directly. Look at the provider directory to confirm your doctors are still in-network, check the formulary for your drugs, and compare out-of-pocket costs. If you find a better fit, you can switch during the Annual Enrollment Period.

Original Medicare and Medigap changes

If you have Original Medicare (Part A and Part B) with a Medigap policy, your Medigap premium may increase in 2025 depending on your policy and insurer. Medigap policies are standardized by the federal government, so the benefits do not change, but the cost does. Some insurers raise premiums annually, and some use age-based pricing that increases as you get older.

Original Medicare itself has no network — you can see any doctor or hospital that accepts Medicare. Your Part B deductible and coinsurance amounts change as described above. If you have a Medigap policy, it covers some or all of these costs depending on which plan (A through N) you have.

If your Medigap premium is rising significantly, you can shop for a new Medigap policy from a different insurer during the Annual Enrollment Period. Rates vary widely by company, so comparing quotes may save you money. You do not need to switch plans if you are happy with your current coverage.

When and how to make changes

The Annual Enrollment Period for Medicare runs from October 15 through December 7 each year. Changes you make during this period take effect on January 1 of the following year. You can change from Original Medicare to Medicare Advantage, from Medicare Advantage to Original Medicare, switch between Medicare Advantage plans, or switch Part D plans.

You can make changes online at Medicare.gov, by phone at 1-800-MEDICARE, or in person at your local Social Security office. You can also work with a licensed insurance agent or counselor. If you miss the important date, you cannot change plans until the next Annual Enrollment Period unless you have a may have access to life event (such as losing employer coverage or moving out of your plan's service area).

If your plan is leaving your area or you lose coverage, Medicare sends you a notice with a special enrollment period that lets you change plans outside the regular enrollment window. Read any notices from Medicare or your plan carefully and act within the important date given.

Questions to ask your doctor or Medicare

Before the Annual Enrollment Period ends on December 7, ask your doctor's office whether they accept your current plan in 2025, or whether they accept any of the plans you are considering. Ask your pharmacy which plans cover your current drugs and at what cost. If you take multiple expensive drugs, the total cost difference between plans can be hundreds of dollars per year.

Call Medicare at 1-800-MEDICARE if you have questions about your coverage, your costs, or how to make changes. You can also visit Medicare.gov to use the Plan Finder tool, which shows you plans available in your area and lets you compare costs for your specific drugs and doctors.

Frequently Asked Questions

Do I have to change my plan for 2025?

No. If you are happy with your current plan and your costs, you can keep it. However, you should review your plan's 2025 changes to make sure your doctors and drugs are still covered and that your costs have not risen significantly. If your plan is leaving your area, you must choose a new plan.

What happens if my drug is no longer covered by my Part D plan?

You can ask your plan for an exception, which may lower your cost or restore coverage. You can also switch to a different Part D plan during the Annual Enrollment Period that does cover your drug. Talk to your doctor about whether a similar drug on your current plan might work for you.

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

If you receive Social Security, Medicare deducts your Part B premium from your check. If the premium increases, your net Social Security payment may go down. However, there is a "hold harmless" rule that protects most people: your Social Security check cannot go down just because of a Medicare premium increase.

Can I switch plans more than once during the enrollment period?

Yes. You can make multiple changes during the Annual Enrollment Period (October 15 through December 7), but only your final choice counts. If you switch plans twice, only the second switch takes effect on January 1. Make your final decision before December 7 to avoid confusion.

What if I cannot afford my Part B premium in 2025?

Contact Social Security at 1-800-772-1213 to ask about premium reductions based on financial hardship. You can also look into whether you may have access to for the Medicare Savings Program, which is run by your state and can help pay your Part B premium and other costs.
